Regional settings influences jdbc stored procedure calls?

Question

Hi,
We have a strange problem: we use a jdbc test client
that does a simple stored procedure call with one
input parameter (integer) and one output parameter
(integer). Like:
"? = callprocedure(?)" . The database resides on a different server.
The problem is: this only works when we use "netherlands" regional setting on the windows 2000 machine that
java client program runs on. If we switch to
"english (united states)" the call gives other results
in the output parameter / returns an error code.
Does this have something to do with the Locale of the
virtual machine? Or do I have to do something with
NLS_LANG to eliminate the behaviour that is dependent on
the windows regional settings? Please help!
Thanks,
Michel Schudel
We use the Oracle JDBC thin driver, latest version.

Ok, here it is. Basically, I first call a stored procedure called SETPARAM which receives two Strings:
a parameter name and a a parameter value. After that, I
call a procedure called RUNSQLKIT without any input parameters. The output parameter is an integer that indicates the number of "cells" in the output message. After that, I start to retrieve the cells but that is not important here. What happens is: with Dutch regional settings, the number of cells is normal (387) but with
US settings, the number of cells is -1 (indicates an error.) Why? I use no dates or floating point values as
input/output!
Jvm version is 1.3.1_08, oracle driver is 8.1.7
(Oracle 8i) thin jdbc driver. Oracle runs on AIX.
conn = m_dataSource.getConnection();
// Setup the input params
stmtInput = conn.prepareCall("BEGIN Pck_Sqlmast.setparam(?,?); END;");
for (final Iterator iter = m_kitParameterNames.iterator(); iter.hasNext();) {
final String sName = (String) iter.next();
final String sValue = input.getParameter(sName);
if (sValue != null) {
stmtInput.setString(1, sName);
stmtInput.setString(2, sValue);
stmtInput.executeUpdate();
// Call the kit
stmtRun = conn.prepareCall("BEGIN ? := Pck_Sqlmast.runsqlkit(?); END;");
stmtRun.registerOutParameter(1, Types.INTEGER);
stmtRun.setString(2, m_kitName);
stmtRun.executeUpdate();
final int iCells = stmtRun.getInt(1);
Hi Michel,
Perhaps you would care to post some more information
including:
1. Entire error message and stack trace you are
getting.
2. The part of your java code where the error
occurs.
3. Java version you are using.
4. Oracle database version you are using.
5. Platform on which Oracle database is running.
Good Luck,
Avi.
