How to stop cq bundles programmatically?

Hi,

    CQ has its own bundles like com.day.crx.crxde-support . I would like stop this bundle programmatically. Please suggest. Your comments are welcome.

 

Thanks,

Arya

Hi Arya,

Curl is already build in you can invoke it by accessing particular url.e.g. http://balawcm.wordpress.com/2013/02/13/curl-it-out-adobe-cq5-curl-commands-and-usage/

Here are two examples of simple usage:

1) We stop the bundle that is currently being activated

 @Activate
   protected void activate(ComponentContext componentContext) throws BundleException {
      componentContext.getBundleContext().getBundle().stop();
   }

2) We stop some other bundle

@Activate
   protected void activate(ComponentContext componentContext) throws BundleException {
      Bundle[] bundles = componentContext.getBundleContext().getBundles();
      //find your bundle and assign it to int found;
      bundles[found].stop();
   }

Hi PuzanovsP,

    Thank you. It's working fine. Suppose if we want to get the bundles in jsp, how can I get them? I'm executing the following -

<% @ page import = "org.osgi.framework.Bundle" %>

<%

      Bundle[] bundles = componentContext.getBundleContext().getBundles();
      for(int i=0;i<bundles.length;i++) {
            %><%=bundles[i]%><%
      }

%>

But I'm getting the following error -

Caused by: org.apache.sling.scripting.jsp.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: 14 in the jsp file: /apps/mysite/components/content/bundle/bundle.jsp
The method getBundleContext() is undefined for the type ComponentContext
11:
12: <%
13:
14:       Bundle[] bundles = componentContext.getBundleContext().getBundles();
15:       for(int i=0;i<bundles.length;i++) {
16:             %><%=bundles[i]%><%
17:       }

    at org.apache.sling.scripting.core.impl.DefaultSlingScript.call(DefaultSlingScript.java:361)

Is componentContext also implicit object? Is there any other way to get them from jsp? Your comments are welcome.

 

Thanks,

Arya.

Hey Dinu,

 

You can stop by invoking a jmx with curl: curl -u admin:admin -F action=stop http://localhost:4502/system/console/bundles/$bundle symbolic name.

You can also stop from Java using the following example: http://stackoverflow.com/questions/7150874/how-to-stop-a-specific-apache-felix-bundle-using-java

 

Thanks,

Peter

 


Hi Peter,

            Do I need to integrate curl and AEM for the first solution? If then how can I do that? Please suggest. Could you please share a sample snippet code for the 2nd solution?

 

Thanks,

Arya
