Hmm, I downloaded the 10.2 version and signed it. I replaced the one I was using with the new one. Now it works again.
The scary thing is that it just up and quit working. I didn't replace the jar or alter it in any way. I sure hope that doesn't happen again.

Can't connect to DBase - Can you send the stack trace for the NullPointerException? I'd be curious to see if it's happening inside Derby or if it's happening in your code because ds.getConnection() returned null - If you're running Derby 10.2, you can go to the lib directory and say 'java -jar derbyrun.jar sysinfo'. If you're running 10.1 then you can go do 'java -cp derbytools.jar org.apache.derby.tools.sysinfo' David Marl Atkins wrote: > Yea, it's tough for me to pin down. > The actual error I'm getting is nullPointerException. > I get it when I try to create the connection object: > > ------------------- > public java.sql.Connection openDBase() throws Exception > { > ds = new EmbeddedDataSource(); > ds.setDatabaseName("CTMCDBase"); > try > { > oCn = ds.getConnection(); > return oCn; > } > catch (Exception exp) > { > throw new Exception("Error in CliDBaseConn.openDBase: " + > exp.getMessage()); > } > finally > { > oCn = null; > } > } > > ----------------------- > > I don't know how to run sysinfo. > If you can tell me where to get the signed derby.jar that you're using > that might help. > I had to sign this one myself so I'm not 100% confident with it. > Again, this app has been working fine and now out of the blue, it > throws that nullPointerException. > > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > On Behalf Of David Van Couvering > Sent: Tuesday, November 28, 2006 1:04 PM > To: Derby Discussion > Subject: Re: Help!
