Tomcat?
Is the driver lib on the classpath of the Tomcat server?

Been a while since I've worked with Tomcat. But its probably something like %CATALINA_HOME%/common/lib
Don't quote me though.

Have a look at this thread: http://www.coderanch.com/t/509405/Tomcat/Loaded-jar-files-tomcat

As I recall, you only need one of the driver libs which you have noted on the server classpath. The key is to identify which one you need.

Sorry can't be of more help.

i've used the "old" way, adding it to the tomcat lib folder everything works fine. Yet if you haven't find a solution , the "clean" solution is to add the path to external jar into the catalina.properties , shared.loader value
 
I agree. Here's the link: http://aspose.com/file-tools
