Thanks Paul,
I am confident the library list is correct. I displayed the library list
for the XMLSERVICE job and used that to replace my interactive library
list and then ran a test from the command line and it worked correctly.
How would I determine a resource problem ?
Thanks for your reply

from your log the cause of the dump is
Object domain or storage protection error for offset X'000000002B25B800'
in object XTOOLKIT PHPUSER 065558.
looks like a library list/resource problem in the webservice call to
XMLSERVICE ... not a problem in the serviceprogram ,or in JDBCR4...

IBMi Version V7R3 and current on PTF's
JDBCR4 version - not sure but I have downloaded again from Scott's web
site.
I have a service program that connects to a MS SQL server and retrieves a
list of records, converts the results into json using yajl and returns the
string.
If I run this from the command line it works perfectly.
If I call externally using XMLSERVICE it fails.
I have run the process in debug and in JDBCR4 the procedure start_jvm()
used to start the JVM , it simply calls the java method java.lang.String
with wwStr = s('Temp String'); which should start a JVM if there is not
already one running.
I have pasted the joblog below.
I have tried submitting the same process to batch using the same job
description (library list) and running under the same user profile and it
completes normally.
I have looked at the dump files created but none of the content is
meaningful to me or for that matter indicates a reason for the failure.
Any suggestions most welcomed - I have been going in circles with this for
quite a while!!
