Description Zuzana Krejčová 2015-10-09 08:38:41 UTC 
Description of problem:
Form modeler doesn't load on Weblogic due to a CompilationException:

javax.servlet.ServletException: weblogic.servlet.jsp.CompilationException: Failed to compile JSP /formModeler/fieldHandlers/CreateDynamicObject/input.jsp
input.jsp:30:2: The code of method _jspService(HttpServletRequest, HttpServletResponse) is exceeding the 65535 bytes limit
<i18n:bundle id="bundle" baseName="org.jbpm.formModeler.core.processing.fieldHandlers.messages" locale="<%=LocaleManager.currentLocale()%>"/>

See e.g. http://futuretask.blogspot.cz/2005/01/java-tip-5-avoid-64kb-method-limit-on.html

This doesn't happen with other tested containers (different jsp compilers).

Can you attach your repo to see your model & forms?

Repo can be found here:
https://code.engineering.redhat.com/gerrit/p/bpms-assets.git
Project is 'formmodeler'.

I tried a bit more manually. The issue depends on the 'size' of the form. This means that on the one hand, we don't hit it all the time on WLS, on the other hand though, with a bit of luck, we can hit it on other containers as well.

If you try with e.g. DefaultValueTest.form, it will take some time, but in the end, the form will load.
If you try FormWithAllFieldTypes.form, it will not load and you will get the exception mentioned above.
(Switch to 'Add fields by...' tabs)

Splitted the components that were causing the issue into smaller ones.
