OS: RedHat 7.1
JVM: Sun 1.3
Start JBoss with run.sh and Hsql hangs on start claiming 'no suitable driver' after a ctrl-c, but if you start JBoss with run_with_tomcat.sh everything works fine. It sounds as if this might be a classpath issue with the run.sh script.
I can recreate this bug on my CalderaLinux machine with an IBM jvm.
can't reproduce this. unpacked JBoss-2.4.3_Tomcat-3.2.3.zip and it works fine with both run.sh and run_with_tomcat.sh. Have you modified your configuration files in any way?
