java.lang.LinkageError: loader constraint violation: while consume web service which is hosted in CQ

Avatar

Level 2

Hi,

We deployed CQ 5.6.1 as a web app in Jboss 5.1.0-GA.

My requirement is to expose soap based web service within CQ, i am using Apache CXF to do this job and successfully achieved this  job in jboss 7.1.1-final.

Now i moved my code to jboss 5.1.0-GA, here my web service successfully got exposed, but when i try to consume this web service i am getting following error stack.

I did n't modify single line of code,every thing is same.Only the difference is jboss 7.1.1-final.I don't know what went wrong, do i need to configure any thing in Jboss 5.1.0-GA ?

Please suggest me

Hi Sai,

Please refer the following post, it talks about exposing the boot classpath in OSGI. Add the following property in sling.properties to resolver class linkage error for the javax.activation errors.

http://spring.io/blog/2009/01/19/exposing-the-boot-classpath-in-osgi/

org.osgi.framework.system.packages.extra=javax.activation;version\="1.1.1

Restart CQ instance after adding this property

Let me know if face any errors after adding this property.

Thanks

Subhan

Hello Sainath,

May be below will help, Did you try to call same webservice outside CQ and see if that help ? That way you would know if it is JBoss integration error or error through CQ.

Hi Yogesh,

Thanks for reply.I followed the link shared by you, unfortunately it did n't work for me. i deployed same code in standalone CQ and consumed from out side of CQ,then also i am getting same issue. but same thing is working fine in Jboss 7.1.1-final, i think Jboss 7.1.1-final has some special configuration or special class loading mechanism to override this kind of issues.

Hi Subhan,

We were able to fix the linkage error by setting this property. But we have a HTML email functionality in our bundle and now it is not working. Do we have any alternate solution for this?

Thanks,

Anusha
