Passing Substitution Parameters to run_Batch_Job Web Service

Question

I've been struggling with setting global variables and substitution parameters for my batch job submitted through the Web Service. I have a simple job with a script that refers to one global variable and one substitution parameter.
Job_param_typeSubstitutionParametersParameter[] parms =
          new Job_param_typeSubstitutionParametersParameter[1];     
parms[0] = new Job_param_typeSubstitutionParametersParameter();
parms[0].setName("$XXX");
parms[0].set_value("Test");
jobParameters.setSubstitutionParameters(parms);
request.setJobParameters(jobParameters);
RunBatchJobRequestGlobalVariablesVariable[] globals =
               new RunBatchJobRequestGlobalVariablesVariable[1];
globals[0] = new RunBatchJobRequestGlobalVariablesVariable();
globals[0].setName("$$YYY");
globals[0].set_value("Test2");
request.setGlobalVariables(globals);
When I pass this request to run_Batch_Job, that call times out after about 5 minutes with a socket read timeout. If I don't set the globals or substitution parameters, the call completes, and the job runs fine.
The script in the job looks like the following:
print('Global: ' || $XXX);
print('SubParm: ' || [$$YYY]);
What might I be doing wrong?

Answer 1

The only log that has relevant data is errorlog.txt (and it clearly identifies the problem--missing quotes as I indicated in my earlier post).
(12.1) 02-25-09 12:47:15 (E) (5624:4360) PAR-010102: Syntax error at line <3>: <print('SubParm: '+$$XXX);>: near <$> found <'$'> expecting <'(', &ERROR, __AL_LOOKUPEX_TRAN,
                                                     __AL_SEARCH_REPLACE_TRAN, __RFC_FUNCTION, __AL_SCRIPT_FUNCTION, __AL_STORED_PROCEDURE, __AL_EXTRACT_FROM_XML,
                                                     __AL_TRAN_FUNCTION, +, AL_UNSPECIFIED_PARAM, CONVERT, a float, identifier, an integer, a null, a quoted identifier, a string, a
                                                     decimal, -, SUBVARIABLE, VARIABLE, -, +>.
                                                     1 error(s), 0 warning(s).
                                                     . Please check and fix the syntax and retry the operation.
So, the real question now is why does the Web Service take 5 minutes then timeout?
I'd really like to be able to handle the error gracefully (without delay). Why is there no server response?
