Re: SQJAVA?

["Joe Sam Shirah" <jshirah@xxxxxxxxxxxxx>]

    Hi Stu,

    "The trace level component can be used to trace the actions that
are performed by the OS/400 module responsible for the Java stored
procedures support...

The trace is enabled by adding the environment variable
QIBM_COMPONENT_TRACE_LEVEL with a value of 'SQJAVA,3'
to the job where the Java stored procedure is executed. The trace
is disabled by removing this environment variable.

Once the trace is taken, it can be dumped with the CL command
DMPUSRTRC either to STDOUT or to a file in QTEMP."

    I just happened to be able to quote that off the top of my head.    ;-P

    More seriously, take a look at

Stored Procedures, Triggers and User Defined Functions on DB2 Universal
Database for iSeries    SG24-6503-01

    See "7.11.2 Tracing" for the info quoted and more about trace/debug.
In addition, I would think you could output exception data to a file for
checking.  However, the example given is for a problem matching
argument types, so the trace may be the only way to get that info.
