Thanks for your replies..
i use jboss4.0.2 , jdk1.5 and mysql 5.0 . For my application i have lib folder so that i got the jars of alfresco 1.2 (alfresco-core,
alfresco-jcr,alfresco-remote-api,alfresco-repository,alfresco-web-client). which is working properly .
I copied 2.1 jar files from WEB-INF\lib from alfresco (alfresco-community-war-2.1.0.zip) but i cannot see the alfresco-jcr jar file.
If i copy this 2.1 jar files and replace those 1.2 jar files it does not work . Is there any problem whether structure has been changed. Pls guide me .
Thanks
