Hi Ajay
based on your feedback I tried a test - by creating an EAR which contains
1>test1.jar - an EJB [ the manifest file having the test22.jar]
2> test22.jar another EJB
3> test2.jar - a common jar[ the manifest file having the test2.jar]why does this point to itself ?
4> testservlet.war - a servlet file in a war
Weblogic deploys them all - I can invoke the EJBs too. But when I try toinvoke
the servlet from the browser - it says the test.TestServlet class notfound! -
this is because the testservlet.jar file which contains this class should be
in WEB-INF/lib of the .war file.
but I see the servlet war deployed from the console! - is this a bug? I amattaching
the EAR file - its pretty self contained and you can try it out in urweblogic
env [6.1 sp3 win2k].
thanks

Hi
So what you say can be summed up as
1> all EJB jars in the same EAR gets loaded by the same classloader.
2>So if in the jar manifest file I write the CLASSPATH to the B thenthe
classlaoder
for the EJBs will also load B.
3> Since the WAR classloader is child to the EJB classloader - theWAR can
also
see the same B.
Yes you are correct.
Now do I have to have the manifest entry[CLASSPATH] for every EJB jartha
I make?
If the same classloader is used for all the jars in the same EAR Ishould
not
need to do that - right?
Is this feature changing in 7.x?
thanks

Hi
You can refer to B.jar from the War and the EJB jar through the
Manifest
files
In EJB jar and WebApp jar manifest files you can have
Class-Path: B.jar
In 6.1sp2 the EJB classloader is same as the Application ClassLoader.
All
EJB's within the EAR are loaded by the same Classloader. WebAppClassLoader
is the child Classloader of the Application Classloader.
Hope this helps

Hi Guys I have a very basic question regarding EJB deployment in
Weblogic
6.1 sp2.
Is it possble to create an EAR file such that -
1>it contains a WAR file [of servlets/jsps/client classes] - A
2>a jar file containing our core server classes[not EJBs] - B
3>a jar file containing EJBs - C
here A and C are definitely getting loaded by different class
loaders
- I
want
the classloader for B to be parent of the classloaders for A and
C
- so
that both
A and C can see B. - is this possible by some EAR/Weblogic specificway.
OR the best solution is to place the B in the main classpath and
deploy
the C
and A in an EAR?
thanks Anamitra
