Re: Startup problem on Weblogic 8.1SP4

If I split up the spring jar and place just the spring-web*.jar files on WEB-INF/lib, weblogic is giving me wicked error messages such as a complete shutdown of the application without any meaningful error message in the log:

<May 10, 2005 1:51:25 PM CEST> <Error> <Deployer> <BEA-149201> <Failed to complete the deployment task with ID 55 for the application test.
java.lang.NullPointerException
at weblogic.servlet.internal.WebAppServletContext.destroy(WebAppServletContext.java:5999)
at weblogic.servlet.internal.ServletContextManager.destroyContext(ServletContextManager.java:196)

at weblogic.servlet.internal.WebAppModule.destroyContexts(WebAppModule.java:761)
at weblogic.servlet.internal.WebAppModule.rollback(WebAppModule.java:739)
...

I've now completely abandoned the spring jsf integration classes (variable resolver and utils) and hacked together my own utilities in combination with jsf-spring. Works like a charm.

No, I haven't. I'm no running on jsf-spring instead.
Perhaps I'll try this later.

Did you try putting spring-web.jar and spring-webmvc.jar in the war and
the other spring-*.jar files in the EAR? I am just curious if that works
because it sounds like a problem that I will run into at some point. My
first JSF application was not in an EAR otherwise I would have had the
same problem.

The whole issue goes away if I comment out my

<application>
<locale-config />

<view-
handler>org.apache.myfaces.application.jsp.JspTilesViewHandlerImpl</
view-handler>

<variable-
resolver>org.springframework.web.jsf.DelegatingVariableResolver</
variable-resolver>
</application>

in faces-context.xml!

Hence, I guess that having the spring jar files inside the EAR
classloader and the myfaces jar files inside the WAR classloader of
weblogic make the whole classloading break apart.
As I can't really put myfaces libraries into the EAR classloader
(myfaces expects them in WEB-INF lib, extracting some resources at
runtime), I'll try to either split up my spring jar or use the
spring-jsf library instead.

Hi!

I've got a little problem with an application based on both
myfaces-1.0.9 and spring running on Weblogic 8.1SP4.
My JSF UI is packed into a WAR, which is then in turn wrapped into
the
applications EAR. The build is done via Maven; so is the generation
of
all JAR/WAR/EAR manifest files.

Followed the "getting started" instructions on the myfaces website,
I
included all necessary jars in my WEB-INF/lib (including
jsp-2.0.jar).
When deploying the application, weblogic starts choking:

On the other hand, when inverting weblogic classloader hierarchy via
weblogic.xml

<weblogic-web-app>
<description>Here goes my description</description>
<weblogic-version>8.1</weblogic-version>
<container-descriptor>

<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
</weblogic-web-app>

everything goes fine (at least for myfaces). Unfortunately, messing
with weblogic classloader hierarchy opens a whole other can of
worms,
so I'ld like to know if there's any standard way to deal with this
kinda problem. Any idea :)?
