Referrring Shared Libs

Question

Hello, I want to compile my webloigc project classes using Ant script. My project depends on struts shared lib i.e wlp-struts-1.3-web-lib (Struts 1.3 facet on the new Project wizard). I want to refer the jar files from these libs and some other following shred libs inside the javac classpath of Ant script.But I am unable to find the location of the jars for these libs inside WL_instalation? Any help. Thanks.
wlp-struts-1.3-web-lib
jersey-web-lib
content-management-app-lib
wlp-services-web-lib
content-management-web-lib
wlp-services-app-lib
vcr-app-lib
p13n-rest-web-lib
sample weblogic.xml...
<wls:library-ref>
<wls:library-name>wlp-struts-1.3-web-lib</wls:library-name>
<wls:specification-version>10.3.2</wls:specification-version>
<wls:exact-match>true</wls:exact-match>
</wls:library-ref>

Hi,
Regarding your query:
"Is it possible in this scenario update a shared library and tell the application to take the new version without stopping the application or interrupting the application’s availability to clients?"
You can always deploy a new version of shared library without undeploying the older one. The manifest file of the shared library will have the elements like extension name, specification version and implementation version , which is read by the weblogic server during runtime when your application tries making the reference/call.
The calls will be routed to the shared library which has the highest specification/implementation version or to the recent library.
Important Note: Ensure to maintain unique Spec/Implementation version number for multiple shared libraries.
Hope this answers your questions !
Thanks,
