How can I active a osgi component only on publish instance or specified author instance in CQ? Is there configuration?

thx

Hi

We are in the setup phase of our new CQ5.4 environment. The replication system basically works both ways, blog comments entered on publish appear back in the author instance as expected.

But the stored data of form input fails to replicate back to the author system. I think the problem is caused on the publish, because no entries appear in the log of agent "Reverse Replication (outbox)". Is there any additional configuration required for form data to replicate?

Hello,

I see these errors like this when vlt committing:

"[WARN ] Newly created node not found by uuid /content/Scripps-from-Demo2/jcr:content: javax.jcr.ItemNotFoundException: f6aa34bf-f403-4e30-bb32-7bb9d8e80c71"

The content in question was exported from a different CQ data store, in order to be imported into a different data store (where all the nodes in my import set would be new to my target data source -- i.e. no conflicts)

Any idea what might be causing this? or how I can get a good vlt import after this error?

Perhaps I am not using this as intended, so i'll describe step-by-step what i'm doing in more detail:

1. in one instance of CQ, where I've done some development work locally, I've done a "vlt co" using filter.xml to check out some nodes i created and edited (or perhaps i used "vlt export")

2. i close that test instance of CQ, and copy those dirs (jcr_root & META-INF) to a different location

3. i startup a DIFFERENT instance of CQ (which has other work i want to merge with what i've exported in #1)

4. i double-check to make sure the copied filter.xml is good, cd to my copied jcr_root and do a "vlt co --force --filter ../META-INF/vault/filter.xml http://localhost:4502/crx/-/jcr:root ."

5. i do a "vlt add *" to what you have under jcr_root

6. in directories like content/ and app/ i update .context.xml to add any new directories i've added e.g. "<Scripps-from-Demo2/>" (i still get error if i skip this step)

7. i do a "vlt commit".

     many "adding....." statements pass by

     then, after "Transmitting filte data", i get a number of "[WARN ] Newly created node not found by uuid" (the error I mentiona at the start of this msg)

     i also get one or two errors like this: "[ERROR] Error during processing of /content/Scripps-from-Demo2/en/products/triangle/jcr:content/par/1_1219674803642/file: javax.jcr.nodetype.ConstraintViolationException: no matching child node definition found for {http://www.jcp.org/jcr/1.0}content"

     before finally: "[ERROR] commit: com.day.jcr.vault.vlt.VltException: Error while committing caused by: javax.jcr.PathNotFoundException: jcr:data"

8. Looking in the directory "Scripps-from-Demo2" (in reponse to the error 1st described), this is what my .content.xml looks like this:

Should having specific "uuid"s trouble me when trying to import these nodes? what about jcr:isCheckedOut="{Boolean}true"?

Am I not using vlt as intended? I realize i could have used Package Manger to package my nodes up per directory as *.crx or *.zip files; but, I did it this way, because we need to be able to store our files & changes to our corporate svn or hg repository. Conversely, other developers must be able to take this code an check it out to their own machines. While this has worked for some of my trivial sample tests, exporting this project has been causing these errors. Any ideas?

Best,

Ken

These instructions: http://dev.day.com/docs/en/cq/current/core/administering/ldap_authentication.html#Switchin g On LDAP Authentication does not seem to be updated for 5.5, because the file crx-quickstart\server\etc\ldap_login.conf does not exist(even the server directory does not exist).

Hi,

i have a requirement, in the multifield one of the field also a multifield. how can i implement this.? any help or direction to solve the problem will be helpful.

Thanks in advance.

The components page section on parsys[1] explains that you can set the sidekick's Allowed Components for a parsys by clicking Design Mode (ruler icon) in sidekick, then clicking Edit on the parsys and putting a checkmark on the components you want.  We are defining templates for our authoring users and I don't want them to have to go through that effort for every page.  I want to define something at the Template level which specifies the Allowed Components so that the user can use WCM New Page and the parsys on the page will already be set up right.  How do I do this?

Our template has sling:resourceType=/apps/hello/components/ourpage, and ourpage has a JSP which specifies:

    <cq:include path="par" resourceType="hello/components/ourparsys"/>

We just copied ourparsys from the foundation parsys.  Inside it has a design_dialog, which I double-clicked in CRXDE Lite and I see the Design View ("Edit Component," "ParSys (Design)").  I put a checkmark on one of the Allowed Components, clicked Save, but the checkmark was not saved.  When I closed this view and double-clicked the design_dialog again, the checkmark was gone, and when I went to WCM Websites and made a New Page from our template the sidekick still did not show our desired component.

So please advise, is there any way to set Allowed Components so it will take effect on all New Page webpages made from a given template?

Hi guys,

I am getting following error when installing the package that contains DAM content.

Hi there,

I was browsing the forums and saw this thread about building a multfield within a multifield:

http://forums.adobe.com/message/4453594#4453594

It suggested several other alternatives instead of the nested multifield approach, but I just wanted to confirm whether or not CQ5 supports nested multifields or doesn't. I have a top navigation that has topics and then sub-topics that are displayed when the user rolls over an individual topic. Therefore, what I am trying to create is a custom xtype that has a pathfield dialog and a multifield of pathfield dialogs (because each topic could be associated with a variable number of sub-topics). I then need a multifield of this xtype because there could be multiple topics associated with a given section of the top navigation.

I'm happy to provide more detail if this description is confusing. Thanks!

I am using the redirect option in page properties to redirect pages but the page just displays

"This page redirects to <Page Name>" in publisher mode.

Why is it not working?

I am not talking about this:

http://helpx.adobe.com/cq/kb/HowToUseReverseReplication.html

and not this:

http://mkalugin-cq.blogspot.com/2012/02/reverse-replication-woes-solved.html

They work for polls and comments, but they don't seem to be working for forms. As far as I understand, the default servlet for forms creates a "sling:Folder" as a data container, under which all form values are set into properties. However, polls and comments are created as an entity(or node) under a container. A working example for comment is under "/content/usergenerated/content/geometrixx/en/blog/2009/02/shapecon_2009_inveg". All essential properties such as "cq:distribute", "cq:lastModified" are set correctly under this node. I tried to copy the idea of this example, but it never works for me.

Here's how I did.

1. I need to make a node as a "cq:Page", since reverse replication only works for this primary type. Let's name it "Page-1"

2. Create a "jcr:content" node under this node, make it as "cq:PageContent". I also set resourceType and template in "jcr:content". I need to make "Page-1" as a content page.

3. Create a data container under "cq:Page" node, make it "nt:unstructured". Let's name it "form_container". All form values are set into properties in this node. set "cq:lastModified", "cq:lastModifiedBy" and "cq:distribute" under this node.

4. Create a "jcr:content" node under "form_container", make it "nt:structured", set "cq:lastModified", "cq:lastModifiedBy" and "cq:distribute" under this node.

Obviously CQ doesn't know what I did and refuses to reverse replicate. Any help will greatly appreciate.

A finished upload will look like this:

/content

    /usergenerated

        /newsevent [cq:Page]

            /1351359963325_1 [cq:Page]

                |

                + form_content [cq:PageContent, cq:distribute==>true, and all form values stored as properties]

                |

                -- jrc:content [cq:distribute==> true, cq:lastModified==>Date Instance, cq:lastModifiedBy==>admin]

Hi all,

  I'm using CQ5 to develop some things. and now i am not so clearly how to post a 'FORM' and accept with a SERVLET.

  I've seen this 'http://forums.adobe.com/message/4932739#4932739' already, and try it. But once i add a new <input /> like :<input name="age" value="age" />.

and i submit this form, then tell me error: javax.jcr.nodetype.ConstraintViolationException: no matching property definition found for {}age

  see the code

   jsp:

     <!-- String action = /content/myproject/en/thanks   -->

    <form id="submitForm" method="post" action="<%= action %>.POST.html" onsubmit="return validate();">

        <input type="hidden" name=":redirect" value="<%=resourceResolver.map(action)%>" />

        <input type="hidden" name=":formpath" value="<%=currentNode.getPath()%>" />

        <input type="hidden" name=":formtype" value="<%=component.getResourceType()%>" />

        <input type="hidden" name="_charset_" value="utf-8" />

        <input name="age" value="26" />  <!-- if i comment this line, it can submit success, otherwise show me Status: 500. -->

        <input type="submit" value="Submit"/>

    </form>

  servlet:

    @Component(immediate = true, metatype = false, label = "QuestionnaireServlet")

   @Service

   @Properties(value = {

                              SlingHttpServletResponse response) throws ServletException,

can anybody told me in details ?

I was having a problem with XPATH libraries not loading correctly in CQ.

I built an OSGI servlet to access an external database using MyBatis 3.2.2.

If I access the servlet directly from its component path,

@SlingServlet(paths="/bin/TestServlet", methods = "GET",extensions = {"html", "do"} )

i.e., "/bin/TestServlet" then it runs fine without any errors.

However if I export functions from the servlet and run then from a component (.JSP),

com.test.Myservice myService = sling.getService(com.test.Myservice.class);

myService.Foo();

It will trigger an path exception:

Caused by: java.lang.RuntimeException: XPathFactory#newInstance() failed to create an XPathFactory for the default object model: http://java.sun.com/jaxp/xpath/dom with the XPathFactoryConfigurationException: javax.xml.xpath.XPathFactoryConfigurationException: No XPathFactory implementation found for the object model: http://java.sun.com/jaxp/xpath/dom

I have found a solution to this problem by editing the sling.properties config and adding:

sling.system.packages.simple=com.sun.org.apache.xpath.internal.jaxp

Which fixes the problem.

My question is why does this problem not happen when directly accessing the servlet via:

/bin/TestServlet

I don't really understand what is going on here. Is there a difference between running by JSP or directly?

Hello,

Marketing team wants to make use of image renditions feature of DAM, but they want the ability to choose from various rendered images and then drag & drop on to a CQ page from content finder. But I found out that renditions are not available in content finder. I am aware of one solution, which is to customize the image component to have a selection of existing renditions of an asset, so that marketing will have the ability to choose from the existing renditions. But I am wondering what is the use of renditions feature, if they can't be accessible directly by users to drag and drop them on to the page or to access them from creative suite of products.

I will appreicate if some one can help me with this.

CQ5 as Windows Service with LDAP Authentication

1 Introduction

• LDAP:  Lightweight Directory Access Protocol
• Used for accessing centralized directory services.
• LDAP is often used to achieve Single Sign On which allows a user to access multiple applications after logging in once.

2 Steps

1.    Install LDAP server,

1)    Double click the file（Download from apache website first）

ApacheDirectoryStudio-win32-x86_<architecture>-<version>

2)    After start the system, Create a new server (CQ5LDAP)

New-New Server

3)    Add group and users and save them

Name: Adobe

Suffix: ou=groups, dc=adobe, dc=com)

Name: Adobe2

Suffix: ou=users, dc=adobe, dc=com)

4)    Start the server

5)    Create a new connection (CQ5LDAP)

Connection name: CQ5LDAP

Hostname: localhost

Port: 10389

6)    Fill in the Authentication information

Bind DNor user: uid=admin, ou=system

Bind password: secret

7)    Right click the connection name, Import users with LDIF Import

2.    Configure repository.xml

• Remove or comment the LoginModule element in the repository configuration (repository.xml). The configuration file can be found in the folder crx-quickstart/repository.
• Ensure that the file ldap_login.conf is in a folder such as crx-quickstart/conf/ of your CRX installation folder.
• Add the following bolded code to repository.xml so that users can login

    <SecurityManagerclass="com.day.crx.core.CRXSecurityManager">

        <WorkspaceAccessManager  class="org.apache.jackrabbit.core.

               security.simple.SimpleWorkspaceAccessManager"/>

        <UserManagerclass="com.day.crx.core.CRXUserManagerImpl">

            <paramname="usersPath"value="/home/users"/>

            <paramname="groupsPath"value="/home/groups"/>

            <paramname="defaultDepth"value="1"/>

        </UserManager>

    </SecurityManager>

3.    Change start.bat and Quickstart.bat

From the command line, start Quickstart with the option:

-Djava.security.auth.login.config=crx-quickstart/conf/ldap_login.conf

    For example:

    32-bit VM:

     java -Djava.security.auth.login.config=crx-quickstart/conf/ldap_login.conf -Xmx384M -jar crx-quickstart-<version>.jar

    64-bit VM:

     java -Djava.security.auth.login.config=crx-quickstart/conf/ldap_login.conf -XX:MaxPermSize=128m -Xmx512M -jar crx-quickstart-<version>.jar

4.    Starting CQ5 as Windows Service

We install CQ5 as a windows service with instsrv.bat located in C:\author\crx-quickstart\opt\helpers.Hence, if we want to use CQ5 service with LDAP. We need to change instsrv.bat and then run instsrv.bat to install CQ5 as a Windows Service.

Replace line 40: set jvm_options=-XX:MaxPermSize=256M

With: set jvm_options=-Djava.security.auth.login.config=C:/author2013/crx-quickstart/conf/ldap_logi n.conf";"-XX:MaxPermSize=256M

5.    Start the CQ5 service with CMD or Service of Task Manager

        c:>sc start CQ5 (or any service name you installed, say cq5author)

6.    Now you can login by LDAP users

I just started with CQ5/CRX/JCR, so I beg your pardon if asking silly questions.

I'm running a CQ5 Standalone Server (CQ_5_5_Quickstart.jar) on my Windows 7 and am fine with accessing it with my browser and the URL "http://localhost:4502".

Now I try to access it via a Java-client using the JcrUtils.getRepository-method, as described in http://dev.day.com/docs/en/crx/current/developing/accessing_the_crx.html.

But this fails with message:

javax.jcr.RepositoryException: Unable to access a repository with the following settings:

    org.apache.jackrabbit.repository.uri: http://localhost:4502/crx/server

The following RepositoryFactory classes were consulted:

    org.apache.jackrabbit.commons.JndiRepositoryFactory: declined

Perhaps the repository you are trying to access is not available at the moment.

at org.apache.jackrabbit.commons.JcrUtils.getRepository(JcrUtils.java:199)

at org.apache.jackrabbit.commons.JcrUtils.getRepository(JcrUtils.java:239)

at AccessJCR.connectJcrUtils2(AccessJCR.java:32)

at AccessJCR.main(AccessJCR.java:16)

I'm not sure about the used URL; I just took it from cited webpage. There is said: "The default server's endpoint URL is http://host:port/crx/server. Make sure you adapt the client-side connection URL in case of customized server installation.".

I didn't customize anything so this should be ok. I will attach the complete Code, hopefully you can give some hints.

Regards,

Ulrich

Hi,

I am new to Adobe technologies & products. I need to explore Adobe CQ5 in detail as a developer.

I am following below link for getting started:

The link is forwarding me to Adobe Licensing Web Site and which asking for user name and password.

My concern is that:

- Where and How can I download CQ5?

- Is CQ5 is available as developer edition?

- Is CQ5 is available free for developers or for non commerical use?

Please guide me.

Thanks,

Tejas

We need CQ5 Developers and Admin training for a few of our team members in Ahmedabad and/or Bangalore.

Can you suggest who would be the best person to contact.
