Steve --
We've had problems with Resin & the IBM JVM -- we're on Resin 3.0.19 and
IBM J2RE 1.5.0 IBM J9 2.3 Linux amd64.
Ours have generally been problems with classloading like below. Often a
redeploy of the web app fixes it, sometimes not.
We are actually about to move off of the IBM JVM to Sun's because of
this (sounds like you don't have that option).

We have run into a little problem trying to deploy one of our web
applications with Resin and IBM JDK 1.4.2. We have the need to use the
IBM JDK due to one of our 3^rd party jar files so we need to make this
work. When we start our application, JSPs compile successfully, but on
startup, we receive several errors related to parsing XML. Here is an
example. We did not receive these errors when we ran with Sun JDK
1.4.2, and did nothing special with regard to XML parsers, it just
worked.

So to attempt to work around this problem, we tried to disable the
cauco parser, in favor of using the xerces parser. We placed the
following in our resin.conf
<system-property javax.xml.parsers.DocumentBuilderFactory=
"org.apache.xerces.jaxp.DocumentBuilderFactoryImpl"/>
<system-property javax.xml.parsers.SAXParserFactory=
"org.apache.xerces.jaxp.SAXParserFactoryImpl"/>
<system-property javax.xml.transform.TransformerFactory=
"org.apache.xalan.processor.TransformerFactoryImpl"/>
I then am unable to compile JSPs with some vague messages regarding
the c standard tag libraries.
[09:50:51.324] Loading .tld files from global classpath
[09:51:15.848] /WEB-INF/pages/admin/ata/app/reg_form_preview.jsp:1:
org.xml.sax.SAXParseException: The prefix "resin-c" for element
"resin-c:out" is not bound.
Has anyone out there encountered problems like these with Resin and
the IBM 1.4.2 JDK and solved this problem? Thanks in advance for any
help.
