Java Database Connectivity (JDBC)

Trying to use the Swingbench tool (latest release) for load testing. Tool will not launch get the below error:

The database is at release 10.2.0.3; we have installed 11.1.0.6 in order to use the java for 1.5 release as this appears to be a requirement of the product. Here is how we have the environment setup:



export ORACLE_BASE=/local1/app/oracle
export ORACLE_HOME=/local1/app/oracle/product/11.1/db_1
export CLASS_HOME=/local1/app/oracle/product/11.1/db_1
export ORACLE_SID=ecomfb
export JAVAHOME=/local1/app/oracle/product/11.1/db_1/jdk
export JREHOME=/local1/app/oracle/product/11.1/db_1/jdk/jre
export SWINGHOME=/local1/app/oracle/swingbench/swingbench
export ANTHOME=$SWINGHOME/lib
export CLASSPATH=$JREHOME/lib/rt.jar:$JAVAHOME/lib/dt.jar:$JAVAHOME/lib/tools.jar:$CLASS_HOME/jdbc/lib/ojdbc5.jar:$SWINGHOME/lib
/swingbench.jar:$ANTHOME/ant.jar


Not sure where we are going wrong with this process and appreciate any help.
