Create Custom Application Loader

Question

I don't know whether this is the right forum to post the question or not.
My question is :
Can I write a custom class loader in Weblogic App server ? My basic requirement is to write a custom application loader with will first load some jar files from some remote machine and then will be loading the application. This jar files should not be made visible by any other application deployed in the the server. The class loader should also be a component of the application itself.
Say for example : The application name is "App1".
Ideal scenario
1) WLS boots up
2) It tracks all the applications
3) Reads some conf (or xml file) to trace the class loader name from App1
4) Adds the class loader to the Loader Repo, if any
5) When WLS feels it should load the applications i.e application loading step comes, it should detect that there is a custom loader associated to the application App1 and transfers control to it.The loader will load accordingly.
I really have no idea how this can be achieved. But if app servers provides extension to there class loader repo then each application can have their custom loaders if needed.
Any suggestion would be highly appreciated.

Hello Pradeep, <p>
I am trying to configure the "Single session Trace" (OSS Note 1090753) but I am not able to see the second Tabs 'Single Session trace"
when I select the logging link in the Administration console of my application.
    - I modified as described the  attribut  "ForceSingleTraceFile" in the visual Admin. 
    - I modified the appinfo and logFileDownload attributs to TRUE in the XCM
    - I rebooted the cluster
Extract of OSS note 1090753
4. Choose the 'Logging' link.
a page with two tabs 'Log Configuration' and 'Session Tracing' is displayed.
The Session Tracing doesn't appear for me !!
do you not why I am not able to see the Single session trace ?
Currenty, the only way is to retrieve trace in the file defaultTrace10.log.  (see my previous log capture)
Thanks for your help
