This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I run the same jar in another Linux Red Hat 32-bit server and it’s OK. The program is connecting to a database in another server. I tried to execute the jar in several JVM (Sun and jRockit) and several versions in both environments, and I keep getting the exception in the Linux Red Hat 64-bitserver. It’s running OK with both JVM in local and in Linux Red Hat 32-bit server.
1) My PC is a Win XP (x86) and I run the program with Eclipse.
2) Linux Server with Exception: redhat-4 (x64)
3) Linux Server OK: Red Hat Enterprise Linux AS release 4 (Nahant Update 5) (x86)
As you didn't post the actual code, it is really hard to say, but my bet is: you're using a simple Statement with literal values, instead of PreparedStatement and bind variables. The national language settings is different on Linux and the numeric format of literal is not valid there. Your code is therefore subject to SQL injection attacks and implicit conversion bugs.
Again, this is only a guess since you didn't provide the code, but this is the most probable cause. If this doesn't help, use the stack trace to locate statement being executed and show us that code.
