hi, In my application, i am using saaj.jar,saaj-impl.jar for webservice call.if i deploy my application in open source jboss it is working fine,but if deploy in RedHat Jboss4.3.0 server,instead of loading my jar it is taking the jboss-saaj.jar from jboss server.so did the below changes. Step 1:-moved the Jboss-saaj.jar from jboss default\lib to lib\endorsed Step 2:Jboss run.bat file i added the below 3 lines for loading my jar while run the application. set JAVA_OPTS=%JAVA_OPTS% -Djavax.xml.soap.SOAPConnectionFactory=com.sun.xml.internal.messaging.saaj.client.p2p.HttpSOAPConnectionFactory set JAVA_OPTS=%JAVA_OPTS% -Djavax.xml.soap.MessageFactory=com.sun.xml.internal.messaging.saaj.soap.ver1_1.SOAPMessageFactory1_1Impl set JAVA_OPTS=%JAVA_OPTS% -Djavax.xml.soap.SOAPFactory=com.sun.xml.messaging.saaj.soap.ver1_1.SOAPFactory1_1Impl java version :-jdk1.6.0_01, Now while deploying my application Exception is throwing. 19:37:28,109 ERROR [STDERR]
