Thanks Jan,
Do you have any idea what the differences are to allow the same code to run under Sun AS7?
I realise that the below simple code change will benefit us in more ways than one - and if I were to revisit this page I would be tempted to completely rewrite it rather than tweak it. Unfortunately our migration testing team have very much based the work involved on no code changes and due to the limited implementation window any deviation from this is going to push us well into next year rather than the end of September....
Many Thanks
Mat

Yes, the correct way to specify any JSP config params in sun-web.xml is via
the <jsp-config> element, as in:
<jsp-config>
<property name="aaa" value="bbb" />
<property name="xxx" value="yyy" />
...
</jsp-config>
Something like:
<jsp-descriptor>
<jsp-param>
<param-name>noTryBlocks</param-name>
<param-value>true</param-value>
</jsp-param>
</jsp-descriptor>
violates the DTD governing sun-web.xml.

I'm not familiar with the "noTryBlocks" parameter, and I don't think it
was ever supported
by Sun. I've done some research, and it looks like this options is
specific to WebLogic.
As mentioned earlier, there would also be no need for such an option in
GlassFish,
since the JSP compiler in GlassFish already implements several
strategies to avoid
the issue at hand, namely:
- Removal of nested try blocks (but there is still a try block for the
main method)
- Custom tag invocations are implemented as separate methods (unless the
body
of the custom tag invocation contains scriptlets)
Therefore, if you run into the "code too large for try statement" on
GlassFish,
the "noTryBlocks" parameter would not help, even if it existed, since
GlassFish
automatically avoids nested try/catch blocks, which is what
"noTryBlocks" is all
about.
The only way around would be to refactor your JSP into smaller chunks
included via <jsp:include>.
