Crystal Report - problem with passing parameters from J2EE app

Question

i'm trying to pass a few parameters from my java application to a crystal report using the code below:
ParameterField pfield1 = new ParameterField();
ParameterField pfield2 = new ParameterField();
Values vals1 = new Values();
Values vals2 = new Values();
ParameterFieldDiscreteValue pfieldDV1 = new ParameterFieldDiscreteValue();
ParameterFieldDiscreteValue pfieldDV2 = new ParameterFieldDiscreteValue();
pfieldDV1.setValue("1056");//dform.getSelectedPeriod());
pfieldDV1.setDescription("termId");
vals1.add(pfieldDV1);
pfield1.setReportName("");
pfield1.setName("@p_termId");
pfield1.setCurrentValues(vals1);
fields.add(pfield1);
// check here for null condition otherwise will throw nullpointerexception
pfieldDV2.setValue("elect");
pfieldDV2.setDescription("allocType");
vals2.add(pfieldDV2);
pfield2.setReportName("");
pfield2.setName("@p_allocType");
pfield2.setCurrentValues(vals2);
fields.add(pfield2);
this report calls a stored procedure (sql server). the report displays the data but the same is not the case when i call ity from my java application. with a single parameter it works fine (even though i get a "Some parameters are missing values" ERROR on the console. But when i pass, say 2 parameters, it give me the above error first and then "JDBC Error: Parameter 2 not set or registered for output"
Can anyone bail me out of this one?
thanks,

I don't know about naming conventions, but could the @ signs in the variable names cause a problem?
How have you set up the mapping in Crystal?
Is this parameter 2 an "out" parameter returning a value?
What version of Java are you using?
Version of Crystal?
What JDBC driver?
