Hi All,
I am using RSA 7.0.0.9 with WAS 6.1 for Java Web Development Project. I am facing a regular issue with WAS. Whenever i make code changes to the .java files in RSA and publish it in WAS (auto-build), the application does not come up i.e. i see a 'Page cannot be displayed'. In the console i can see the below shown error log:
The workaround i found is that, i need to stop and restart the WAS Server everytime i make the code changes, then it works fine ie application launches. Since i am working on a large development project, i don't have bandwidth to keep on restarting the WAS everytime i write new codes into .java. It's highly time-consuming.
Can you anyone of you please tell me:
1. If this is already a known issue and a fix pack is readily available. If yes, then i request for some details.
2. Or Is there any other workarounds that can be applied onetime.
Requesting your help in resolving this error!
Error Log found in Console:
