Can't move JSSE app from one iSeries to another

I'm trying to move a working online payment application from one
iSeries at V5R2 to another iSeries at V5R2.  I get

The documentation for the pure Java JSSE provider is not easy to
locate (the obvious documentation points to changing to the native
provider.)  DeveloperWorks throws me 500 errors so I can't check
there.  Ignite/400 doesn't seem to have any info on JSSE; the archives
here have Shannon trying to get it going but I think he was using JDK
1.3 (when JSSE was an extension and not part of the base Java
implementation.)  Google didn't net me anything useful either.
My task is complicated by the fact that the Java programmer who did
the original install of this had lots of problems on the first box,
and as a result there are copies of the JSSE extension, expanded jar
files, copies of jar files and so on scattered throughout the machine.
The programmer is gone and what ever notes were made are gone as well.
This makes it difficult to find a canonical 'working' configuration on
the 'working' machine.
If there is a good reference for implementing JSSE on iSeries with JDK
1.4 I would deeply appreciate knowing about it.
