Re: global resources
Just for your edification, FYI the other ones you are currently using are for TOMCAT's classes, not yours.

Re: global resources
It might help if you described what you're doing in a little more detail. What are these classes you want commonly accessible? Are they in jars? Packed correctly, etc.?

Re: global resources
I want both... I have some classes that are unpacked, that I'd put in the common/classes dir... and some jars... along with them is the oracle driver (classes12.jar)... when I execute the JSP I get the exception thrown when the driver can't be found... if I take this file (classes12.jar) and place it in mywebapp/WEB-INF/lib it works fine... it feels to me that this package is the only one tomcat isn't beeing able to share across webapps... all other classes and libs works fine... .:| Christian J.

Re: global resources
Hello Christian, By chance, are the libraries that you put in TOMCAT_HOME/lib refer to libraries that you put in your webapp's WEB-INF/lib? If so, this just isn't going to work. The WEB-INF/lib libraries can see libraries in TOMCAT_HOME/lib, but not the other way around. For instance, the developers at Log4j say that you should have log4j.jar in each separate webapp's WEB-INF/lib directory. However, this imposes itself upon any libraries that are using Log4j. They will need to also be inside WEB-INF/lib as well where, if Log4j was designed a non-static way where it could exist in TOMCAT_HOME/lib and serve all webapps with Loggers without running into each other, then you could have the libraries that reference log4j safely in TOMCAT_HOME/lib. If you didn't understand that, if all else fails, just put everything in WEB-INF/lib except for XML and DOM libraries, which are forbidden in the child classloader, and stuff like DBCP which both Tomcat and your webapp need access to (TOMCAT_HOME/common/lib).

Re: global resources

Re: global resources (better explained)
pay attention to the order of classloaders -- i would jar your classes and put them with the oracle classes, to ensure they're loaded in the same space. I have said this till I'm blue in the face, but so many problems mysteriously go away when you use jars instead of just throwing class files in xxx/classes. cheers fillup On 5/29/02 12:20 PM, Christian J.
