Hi All,

I need to implement Ajax functionality in my component.

The requirement is,

1. On clicking on a button Java servlet needs to be invoked.

2. In the servelt, need to access CRX nodes and store a particular value.

3. Back in the component, i need to retrieve this value(this can be doneby accessing the node value).

4. Page should not be refreshed.

How can i implement this? any sample code will be helpful to understand the ajax with sevlet implementation.

if there are any other possiblities, kindly let me know.

It is very urgent and needs to implement is as soon as possible.

i am in very needy situation.

Any help will be really helpful.

Thanks a ton in advance.

Regards,

Raja R

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 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.

Ulrich

Hi,

I have published a java bundle by right clicking and select 'Build Bundle' on the 'bnd' file, the bundle gets deployed properly on the 'Author' instance, but the 'publish' instance deploy failed.

The code currently works in 'Author'.

How do I replicate the bundle from Author to Publish? Does 'Build Bundle' only deploy the bundle to 'Author'? If yes, step by step how do I replicate the bundle to Publish?

Thanks.

Hey everyone,

     Just wondering how most of you do development for CQ5. I did have the developer training and we used CRXDE. Recently however we have consultants that do not recommend it. They recommend Eclipse. It is my understanding that CRXDE is Eclipse but cq-ified. Is CRXDE still distributed with CQ?

     We are just about to begin a huge project and I am trying to decide if I want to use Eclipse or CRXDE. My impression was that there were spcific features with CRXDE that relate to CQ that Eclipse would not have. And the consultants argue that CRXDE is obsolete? I'd rather use CRXDE since it is what CQ came with and all the documentation I have from training is in CRXDE.

     Can anyone help?

Hi,

I have a requirement to integrate our CQ5.5 based application with a third party. As part of this, I have to use some jar files. After lot of digging, I realised that the way to use external jar files is to create an OSGI bundle wrapping these jar files.

So, I tried to do the same, but when I see the service details in system/console, I see errors. Can someone please suggest what could have gone wrong?

I have to use 3 jar files. So, I placed them in lib folder as shown in the screenshot below.

Ibuilt the bundle using .bnd file. It generated a jar file in install folder and I am able to to see its details in system/console/bundles. When I try to view details of the OSGI bundle that is installed, I see errors as follows:

We have our public website that runs on CQ5.5. We want to do Akamai integration for the published content.

1. How is Akamai integration done in CQ5.5?

2. We want to akamai both the content and dam assets. Is the akamai integration different with content versus assets?

3. With content, the content on site is frequently updated and activated. That would invalidate the dispatcher cache everytime the change happen. How does Akamai rebuild its cache everytime the dispatcher cache is invalidated?

Hi All,

          Hope you all are doing great. Have a qn regarding the packge export via package manager. I am trying to export all the users and their permissions from one env to the other. I can get the users and groups but not their permissions. Can any one suggest me a way of how to do this? I was not able to get the include/exclude filters right..

Regards

Hi.  We're running CQ5 5.5 SP1 and I'm trying to setup an author instance on a machine at a disaster recovery site. I want the DR author instance to be clustered with our existing non-clustered author node on our staging server.  If I get this to work, I'll redo it with the production author server, which will leave us with a hot backup server in the case that the primary data center goes dark.

I cloned the "master" author instance on our staging server using the CQ backup facility.

I restored that backup onto the DR server and proceeded to follow the directions found in the "Manual Slave Cloning" section of http://dev.day.com/docs/en/crx/current/administering/cluster.html

I then restarted the newly cloned slave isntance and saw that that it had automatically been added to the repository/cluster.properties file found on the staging master server.  This implied that the two servers were now linked.  You can also see this in the new slave's error.log file:

30.11.2012 08:06:56.801 *INFO* [FelixStartLevel] com.day.crx.core.cluster.ClusterController Trying to connect to a master, as the file clustered.txt exists.

30.11.2012 08:06:56.987 *INFO* [FelixStartLevel] com.day.crx.core.cluster.ClusterController Node author-dr started as: slave, connected to address: /XXX.XXX.XXX.237:8088

The problem is, the cloned slave author instance will not come up properly.  I see the following error in the logs/error.log file:

30.11.2012 07:54:24.876 *ERROR* [FelixStartLevel] com.day.crx.core.data.ClusterDataStore Unable to download data with identifier: Unable to store record.

30.11.2012 07:56:08.669 *ERROR* [FelixStartLevel] com.day.crx.core.data.ClusterDataStore Unable to download data with identifier: Unable to store record.

They seem to continue as long as the instance is not shut down.  While this is happening, attempting to connect to the CQ admin at http://dr-hostname:4502/ results in a simple "Not Found" error in the browser, which is what you see when you attempt to connect to the admin when the instance is first starting up.

This implies that perhaps the instance is never starting due to this problem.

Can anybody suggest what the issue might be?  I had no success with creating a new quickstart instance and using the GUI to join the existing author in a cluster.  The "Loading..." message showed for a long time before disappearing with nothing appearing to have worked and no error message.

Hi ,

I am creating a custom tag library and want to use it in one of the components I have created. I have made a bundle inside src/com.mycompany.test.TestBundle/com.mycompany.test.TestBundle.bnd and created my java tag class inside com.mycompany.test.TestBundle/src/main/java/com/mycompany/test/DateTagClass.java and the tld in com.mycompany.test.TestBundle/src/main/resources/META_INF/dateTaglib.tld. Here is the code for both the java tag class and the tld

----------------

tag class

package com.mycompany.test;

import java.io.IOException;

import java.text.DateFormat;

import java.text.SimpleDateFormat;

import java.util.Date;

import javax.servlet.jsp.JspException;

import javax.servlet.jsp.JspWriter;

import javax.servlet.jsp.tagext.SimpleTagSupport;

/**

public class DateTagClass extends SimpleTagSupport {

    public void doTag() throws JspException, IOException {

    JspWriter out = getJspContext().getOut();

    out.println(getTodayDate());

    }

   private String getTodayDate() {

        DateFormat df = new SimpleDateFormat("dd MMMM yyyy");

        String formattedDate = df.format(new Date());

        return formattedDate;

    }

}

--------------------------------------------------

I am trying to use it inside a component jsp that I have created as :

<%@taglib prefix="date" uri="src/main/resources/META_INF/dateTaglib.tld"%>

But with the above taglib include in place, all I see is a blank page. I am trying this on author and have not pushed it to publisher yet. I believe it is not able to recognize the tld. Could you please help me on this.

Thanks

Greetings everyone;

  I'm trying to create a website with some components that I get from a imported site... So far, so good, but when I try to drop a "column" component in my website from the components little window (even when I select the 2 columns or the 3 columns), the is no one column layout and the "columns" doesn't exist

  In Geometrixx samples, the columns got layouts like "2 columns, 50 x 50 x" and others, but none is listed on my Column Layout dialog (editing the component). I try to find the source-code of the component, but without success. Can someone tell me how to get real "columns" structures on my site?

  Some images:

I am getting a 404 for my pages when trying to download the userinfo.json and dict.en.json from /libs/cq folder.  What causes those two files to be included?

Hi Everybody,

I'm new to CQ and really enjoying it.  I have a question if someone can please help?

Can anyone help me understand how sling resolves a page component that has a resourceSuperType of  foundation/components/page ?  I created a page structure similar to the geometrixx pages, and have the following page component.

components/page/contentpage

body.jsp

content.jsp

footer.jsp

header.jsp

Therefore I discovered that I can override the body.jsp as this is the page selected by sling (I originally had contentpage.jsp).  Also using this structure I understand that if I have another template and page component I just extend the above "contentpage" component and override "content.jsp" keeping my web site structure (Nice!).

But what I don't understand is how how sling resolves to the body.jsp as the preferred script in the first place? Can anyone help me understand?

Thanks

We recently had our website security tested and one of the issues was that it was vulnerable for XSS attacks. I did some reading on the web about this and came across the package XSSFilter as part of the CQ installation. Can anyone give some more information on how I should use this package?

Also, is standard XSS filtering not automatically applied in CQ? I read the following paragraph about it on Day's website and I find it a bit dubious:

"CQ applies the principle of filtering all user-supplied content upon output. Preventing XSS is given the highest priority during both development and testing."

If this isn't applied by default can we expect this to come out in a later release of CQ?

Many thanks!

I can't wait for Adobe CQ6! CQ5 is historical!

Also share me the links to download the tool, learning material etc if any one has?

Thank you
