I need help with the following scenario.
Currently my application runs with WAS 3.5 and We have a file based caching implementation. The data ( files ) gets updated with a cronjob, this process runs out of WAS 3.5 env.
WAS 3.5 process reads the data from these cached files and displays the info.

Some where I read that in WAS 5.0 we need to deploy the application as a WAR ( Contains all images, jsp, jar, files, etc ) file. If I have to move this application to WAS 5.0 Can I still have the above file based caching available to the WAS 5.0 process ?
Please comment on this
Thanks,
VN

If I understand what you're asking for the answer is no, it won't work. However, WebSphere 5.0 has its own very sophisticated caching mechanism built in. You will need to rewrite your application to use it, probably replacing updating files on the hard drive with refreshing dynamic content in a JSP that is then cached.
Read in the WAS 5.0 InfoCenter about "Dynamic Caching" or do a search on that subject in the WebSphere Developer's Domain. I would STRONGLY suggest that you get hold of someone (a consultant or other experienced developer) who knows how WebSphere 5.0 and J2EE 1.3 works and redesign your application to work within the new limitations and capabilities.
