Fatal PL/SQL error when calling imported java code

Question

Hi,
I'm developing reports using Report builder 9.0.2 under Win2k and I have the following problem:
I select data into fieds A and B.
I created 2 formulas fA and fB that call a PLSQL function from my report in order to convert A and B based on other data.
I also have a formula fC which is actually fA-fB
I have 3 summary columns on fA, fB and fC. I don't display any of those columns on the report but I created other formulas columns fA_Fmt, fB_Fmt,... to format the values using an imported java class.
This java class is static.
so fA_Fmt looks like this:
function fA_Fmt return Char is
begin
return MyJavaClassPackageName.formatValue( :fA, report_global_variable );
end;
When I run my report under report builder, I get a REP-1401 report error like "fA_Fmt formula: fatal PL/SQL error occured
ORA-39565: Message not found, product RDBMS, facility: ORA"
This happens randomly on any of the formulas.
Sometimes I even get a java.lang.StaskOverFlowError and I have to close and restart report builder.
I've tried to debug and I even caught the exception.
The parameters passed to the java method are fine.
The exception number is 105101 and after a couple of exceptions like this, visual C++ runtime library tells me there's a runtime error in rwbuilder.exe and the application crashes.
I don't know if it's Java, if it's Report builder or even Win2k.
Anyway, I'm stuck with that and I don't know what to do to fix it.
Any idea or work around?
Thanks
Manu

Hi Manu
I suspect the line given below:
return MyJavaClassPackageName.formatValue( :fA, report_global_variable );
Do not pass report values directly. Instead, assign it to a temporary variable and try again. See if this works:
temp1 <Variable_Type>;
temp2 <Variable_Type>;
temp1 := :fA;
temp2 := report_global_variable;
return MyJavaClassPackageName.formatValue( temp1, temp2 );
Note: You may also hit Fatal PL/SQL errors if the arguments happen to be invalid.
