Calling SQL 2000 Server SP Using JDBC

Hi this is my first post

I really needs some help

I have been stressing with issue for last few days.

I have a stored Procedure ramApplicationAddTest, I can run it through SQL Query Analyser without any problem.

I can call this using JDBC and it works, here is how I make call I make to SP

var con1 = DBDriver.getConnection ("alias:ProclaimConnect");
var stmt = con1.prepareCall( "{call ramApplicationAddTest(?,?,?,?,?)}");
stmt.setString(1,'BuildApp');
stmt.setString(2,'BASwimPool');
stmt.setString(3,'Test Test....');
stmt.setString(4,'');
stmt.setFloat(5,0);
stmt.execute();
stmt.close();
con1.close();

I also have another SQL 2000 Stored Procedure called
RamApplicationAddTest1, I can run this SP also through SQL Query Analyser without any problem.

But when I try to run this using JDBC it, gives me following Exception.

SQLState[ERR-Unexpected]ErrorCode[0]Message[java.lang.NullPointerException
at com.hs.form.jdbc.JDBCErrorhandler.isMssqlConnectio nErrorInTx(JDBCErrorHanlder.

An exception 'DatabaseQueryException' has occurred at DatabaseQueryClientWinInetImpl.cpp (291).

var con2 = DBDriver.getConnection ("alias:ProclaimConnect");
var stmt = con2.prepareCall( "{call ramApplicationAddTest1(?,?,?)}");
stmt.setString(1,’BuildApp’);
stmt.setString(2,’BASwimPool’);
stmt.setString(3,’Test’);
stmt.execute();
stmt.close();
con2.close();

I hope somebody can give me some hints to fix this.
