Microsoft XP SP1

[neilkonitzer]

I am tasked with troubleshooting a Java application that worked perfectly fine until the client systems were upgraded to Microsoft XP Service Pack 1. it appears that the database connections are no longer working. Has anyone heard of anything in this upgrade that would cause Java applications to stop working along with a solution?

Thanks in advance!

Check the simple stuff first before diving into the code.
- Is the database up, accepting connections etc.
- Can the PC ping,nslookup etc the db server
- Can you open a SQLPLUS console (or similar) to the database by hand.
- Write a small test program to make a connection, and perform a simple select statement.
- Check permissions on tables
- Check error logs
- Can another PC withough XP-SP1 execute the code successfuly.
- Are the code versions the same, the JDBC drivers correct
- Are there no conflicting jar files in the CLASSPATH (don;t forget jre\lib\ext)


If all of these are fine, then, and only then start debugging the code !
