Hi Mathew,

I was experiencing exactly the same problem, and sort of got it to work by
actually recompiling a few classes. The problem had to do with the driver
not finding jdbc2.0. Unless it was there, one of the objects it was using
was left null, hence the NullPointer exception. Still not sure why it was
happening, I had jdk1.3 installed which comes with jdbc2.0.
Like I said, by hacking a few classes, I was able to get it to work for
select queries, but when it came to update statements, it was throwing 0x79
packet or something like that, I'm sure people here have heard of it.

Try using Curt Hagenlocher's release instead, it seemed to have worked for
me without problems so far:

         try {
          Class.forName("com.internetcds.jdbc.tds.Driver");
          java.sql.Connection con =
java.sql.DriverManager.getConnection(url, username, password);
         }catch (Exception e){
            throw(new UnavailableException(this, "Database connection
failure"));
         }

replace url with:
 jdbc:freetds:sqlserver://host:port/database

user/password are for access to sql server, via sql server authentication.

Subject: [freetds] Nullpointer exception


Hello,

I think I've brought this up before, but I am curious if anyone may have any
ideas or suggestions.

I have downloaded the latest freetds_jdbc.jar from freetds.org, pointed
classpath to it etc etc...
When I try to use it, to create a connection, it throws
java.lang.NullPointerException
java.sql.Exception

I have jdk 1.3 installed, running on win2k.

If anyone knows what it is that I'm missing here, please let me know.
Thanks.
