Swingbench error when starting swingbench. (more like java problem)

Question

Platform: Solari 10, Oracle 10gR2.
I downloaded the swingbench for load testing from http://www.dominicgiles.com/swingbench.php for version 2.2 and 2.3. and unzip it in Solari 10 at $HOME (/export/home/oracle/swingbench). As result, it create a folder ./swingbench with all objects in it. I edited the file swingbench.env:
export JAVAHOME=/usr/java
export SWINGHOME=$HOME/swingbench
And leave the others as default. I followed the README.txt run the script swingbench.env to setup the env variables and get into $HOME/swingbench/bin to run ./swingbench to expect a GUI window. But I got this error:
fx1db01|inbound|/export/home/oracle/swingbench/bin $ ./swingbench
Exception in thread "main" java.lang.UnsupportedClassVersionError: com/dom/benchmarking/swingbench/SwingBench (Unsupported major.minor version 49.0)

What I can do to fix the problem?
Thanks for help!

Answer 1

You are trying to run a program compiled with target class version of 1.5 on a JRE version less than 1.5. Use JRE 1.5 or higher.
