Re: *SPAM* Re: How to change the CLASSPATH in tomcat 5.028 for a concrete webservice
Hi David I'm using tomcat 5.028 in Ubuntu 6.10 . I've written a java applicattion wich uses a wrapper to communicate with an applicattion written in C, wich is the core of my applicattion. Both the wrapper and the core are third party applicattions, and because of that i don't have the source code, I just have the API. The third party sent me an example application wich uses the core. And, as I could see in the script wich lauches the application, this folder should be added to the classpath in order to be able to be located by the wrapper applicattion. The documentation of the wrapper just says that this folder has to exist with an specific name. My problem is that my applicattion works fine launched from shell (it founds the folder and uses the core perfectly) but it doesn't work as a webservice. It is not able to find the resource folder (let's call it cfg). As I can see in the catalina log, the application tries to load the resources (via ClassLoader I guess) and then launches an exception saying that is not able to find it. The client gets a HTTPErrorCode0. I think I've tried everything to make it find the folder, but I wasn't successful. do you have any idea? thank you very much David Smith escribió: I wold STRONLY recommend you DO NOT touch the CLASSPATH env variable. It's just a horrible idea. What is it about your webservice that requires the alteration of CLASSPATH? Can you describe that a bit more? The standard classloader structure works very well in virtually all other cases. --David Tomás Tormo wrote: Hi again I've tried to set the classpath in catalina.sh in order to have my own classpath set when tomcat starts up ( I show it in catalina.sh as well and it looks good).

Re: *SPAM* Re: How to change the CLASSPATH in tomcat 5.028 for a concrete webservice
Can you post a) the working classpath from the command line and b) the stack trace you get when it's launched as a webservice? One other thought that comes to mind is you might want to check all your environment variables as a user and as a webservice -- see if the installation created something that's not in the profile tomcat is running under. I still think setting CLASSPATH should be an absolutely last resort. --David Tomás Tormo wrote: Hi David I'm using tomcat 5.028 in Ubuntu 6.10 .

If you *really* need to do this, then put the third-party jar in shared/lib and edit conf/catalina.properties to add your external directory to the classpath. thank you very much David Smith escribió: I wold STRONLY recommend you DO NOT touch the CLASSPATH env variable.
