hi all,
I am so disappointed to tell you it didn't work according to what Robert said
yet. The issue:
the standard war package without specific weblogic config file extracted into
autodeploy dictionary of weblogic9.2 did work well! But the war package didn't
work. The exception as follow(by the way I am using the axis2.1.3.):
Caused by: java.lang.NullPointerException
at org.apache.axis2.extensions.spring.receivers.SpringServletContextObje
ctSupplier.getServiceObject(SpringServletContextObjectSupplier.java:58)
the corresponding code is :
Parameter servletConfigParam =
axisService.getAxisConfiguration().getParameter(HTTPConstants.HTTP_SERVLETCONFIG);
I am sure that axisService.getAxisConfiguration() was NULL!
I think http://ws.apache.org/axis2/1_3/app_server.html is stale. As the link
inside the web is still about weblogic8.1. The most thing is that It didn't
work when I did it according to the instruction.
config is below:
the axis2.war\META-INF\weblogic-application.xml file :
<?xml version="1.0"?>
<weblogic-application xmlns="http://www.bea.com/ns/weblogic/90";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<prefer-application-packages>
<package-name>com.ctc.wstx.*</package-name>
<package-name>javax.xml.*</package-name>
<package-name>org.apache.*</package-name>
</prefer-application-packages>
</weblogic-application>
the axis2.war\WEB-INF\weblogic.xml :
<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/90";>
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
</weblogic-web-app>
whether the app is deployed by war package or not, the exception is :
java.lang.ClassCastException: com.ctc.wstx.stax.WstxInputFactory
at javax.xml.stream.XMLInputFactory.newInstance(XMLInputFactory.java:136
)
at weblogic.servlet.internal.WebAppHelper.addListenerElements(WebAppHelp
er.java:244)
at weblogic.servlet.internal.WebAppHelper$IOHelperImpl.parseXML(WebAppHe
lper.java:224)
at weblogic.descriptor.DescriptorCache.parseXML(DescriptorCache.java:324
)
at weblogic.servlet.internal.WebAppHelper.registerTagLibListeners(WebApp
Helper.java:174)
Do you have any advice? Thank you very much.
Regards
javafoot
