How to migrate .war archived webservice to WebLogic 10.0.3

Question

Hi everyone.
I have been requested to deploy a War file as Webservice on Weblogic Server 10.0.3 (installed on Redhat EL 5.0, I used Sun jdk 1.0.6 distributed along with installer bin file). This file
was run well on TOMCAT 5.0.28 server.When hacking into this WAR file I know it use Xfire(1.2.2) as a base to construct Webservice, hibernate(3.0) to mapping with database (it use only a
services.xml putting on META_INF to describe service as far as I know). Firstly, I use Adminstration Console, go to deployment link and deploy as this tool say, the result in Adminstration
Console tell me I had deployed succedfully but when I digged into exploded directory of WAR file, I can not see any .class file under WEB_INF directory and my client actually can not access provided services. I thought there is problem when use Application Console to deploy so I switch to use other tool like wlst or ant task but result is the same. Finally, I had to upload WAR file, use jar to extract WAR file to a directory and use Adminstration Console to deploy the whole directory as a Web Application. All class file are under WEB_INF directory. But when I use a client to access services I got exception as below on WebBrowser
Could not invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: Fault: java.lang.NullPointerException
and no more detail (or I do not known where to get log file). Because I am just a system maintainer and do not know much a bout J2EE Webservice specification, I just read some materials
and know that WebLogic support Web Services 2.1 (JAX-WS) and XML-Based RPC 1.1 (JAX-RPC). So I desire to know some thing below:
1) What kind of Webservice in WAR file do I have (Web Services 2.1 (JAX-WS) and XML-Based RPC 1.1 (JAX-RPC) or something WebLogic do not support?
2) How to migrate my WAR file to Weblogic by a very common way?
3) How to get log to make more detail about exception above on WebLogic (does log4j archive this work?) ?
Thank you so much

Answer 1

Hi all,
May be I found the problem. The compatibility between Weblogic and hibernate 3.0 relating to antlr-2.7.5H3.jar library. Although I include all application's jar file in CLASSPATH when start server
but Weblogic seem not to see my antlr-2.7.5H3.jar and use its default antlr library instead. So I set my antlr-2.7.5H3.jar directly into PRE_CLASSPATH variable on $DOMAIN_HOME/lib/setDomainEnv.sh
file like below:
PRE_CLASSPATH="$DOMAIN_HOME/lib/antlr-2.7.5H3.jar"
export PRE_CLASSPATH
By now my application use the desired lib and Webservice work fine.
But I wonder if this is a good solution, is there any other good practice to set CLASSPATH for this situation? setting PRE_CLASSPATH is correct point and having no affection to the whole domain
in the case there are more application reside in the domain?
Thank all.
