Increasing the blocking timeout means that you are sure that the connections are held for longer time in your application code .
That means that you have some genuine long ruinning SQL's which can't be optimized  anymore and the server peak load is consuming all the connections .
The first things you should try is to increase the pool size and if this can't be don't then you can go and increase the blocking time .

Yes it is there , don't feel lazy to run http://localhost:8080/jmx-console when Jboss3.2.2 is running .
If you get lazy in starting the Jboss3.2.2 then look for the jmx-console folder in the $JBOSS_HOME/server/default/deploy/jmx-console.war :)

Finally think of doing SQL tunining , I guess you need it .
