unstable jasperExcption with custom taglibs?

[elh.maayan]

hi..

we are using jboss 3.2.5 with our own web development framework, which
uses custom taglibs,

the pages are being developed using xml format, and then framework
creates jsp with custom taglibs.

problem is during run-time (after we create new pages) SOMETIMES i
get the jasper excption:

An error occurred at line: 5 in the jsp file: /underwrite/view/jsp/
handleapplica
tion/handle_application/handleApplication.jsp
Generated servlet error:
C:\java_app\jboss\3.2.5\server\pmp\work\jboss.web\localhost\pmp\org
\apache\jsp\u
nderwrite\view\jsp\handleapplication\handle_005fapplication
\handleApplication_js
p.java:123:

if (_jspx_meth_pmp_textField_0(_jspx_th_pmp_panel_0,
_jspx_page_context)
)
^
1 error

now i've checked the page being generated and it's ok, and we think it
might be something to do withhow jboss loads the jar , maybe the jar's
base classes needed for the custom tags isn't loaded yet,
i don't know jboss, but i was wondering if there is any way i can
locate this error?
