Just put "phpsrvlt.jar" in the $CATALINA_HOME/lib directory, and it will be made available automatically. Alternatively, you can put it in the /WEB-INF/lib directory of your web application itself. > One thing I found out is that CLASSPATH is beeing overwritten by > catalina.bat, which caused the phpsrvlt.jar not be found.
