I am working on a migration assignment,
The code has jsp pages making use of tld's.
One of the jsp pages throws error when <html:form> tag is used. I am not able to find the exact cause of error as the errors are handled by another jsp error.jsp, which gives the error description as "Unknown Error".
Please guide as what could be the cause of such an error.
If you use webas 6.40 sp14+ or 7.0, go look in the nwa logs http://<host>:50000/nwa/ it will ahve more infos.
If you use an older version, you should try to enable stacktrace for your application (if it's b2b/b2c you can edit that parameter when deploying with the deploy tool, it's called something like show.stactrace or enable.stacktrace, set it to true so you will see the full error instead of the error.jsp).
If that does not help, provide more infos on what platfrom you are using.
