Dear All, Earliar I got my application running on java 4 and jboss3.2.3,and it was running fine. Few days back,I had changed my java version to 5 and jboss to 4.0.2,and from then i am facing problem with executeBatch() method.My jboss4.0.2 console is giving following error, (I am executing executeBatch on PreparedStatement) java.lang.NoSuchMethodException: org.jboss.resource.adapter.jdbc.WrappedPreparedStatement.executeBatch() Also,even after reverting back to earliar versions of both,i am facing the same issue on jboss3.2.3. Please do the needful. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4133540#...
