Hello,

I have made a simple test program for DataGateway that makes a simple
query to Fulcrum database. The funny thing is that it works on some
computers, on others it doesn't.

The error message:

 Exception in thread "main" java.lang.VerifyError: <class:
borland/jdbc/Broker/Resul....method: _$5 signature: <>V> Expecting to
find
unitialized object on stack
   at borland.jdbc.Broker.ResultSet.getMetaData<ResultSet.java:1366>
   at testi.main<compiled code>


The problem is in handling the result set:

while (rs.next()) {
	System.out.println(rs.getString(1));
}


If I take that part of the code away, everything works fine.

Any idea what's going on?

Hello again,

I found the solution myself. With newer version of DataGateway.zip file
(March 11 1998) the program works.

Timo

I am having the same problem when I deploy from JBuilder C/S ver 2 (ver
1 is OK).  Where can I get a copy of the newer DataGateway.zip file?
