Hi,
I try to get javamail working. Using tomcat they claim that the activation.jar and mail.jar must be under tomcat/common/lib and not in webapps…/WEB-INF/lib.
How can I set the classpath for eclipse AND deployment correctly. When moving the jar-files from the eclipse project Web App Libraries Folder into the tomcat/common/lib directory, the editor claims that the classes can’t be resolved (of course) and deploying the project leads to a unresolved compilation problem. Any hints where to adjust this in eclipse with myeclipse tomcat deployment?regards

Dani,
Please try to add libraries to Project Build Path (right click on your project; choose Properties, Java Build Path, tab Libraries, Add External JARs).

That was also what I expected to be the right place to add the library, but if I do so, the eclipse editor is fine (finds all the classes), but when I run the the application under tomcat it claims the following:

Java 1.4 changed the rules as to how packages beginning in java.* and javax.* get loaded. Specifically, they only get loaded from endorsed directories.
Please try to copy your libraries to TOMCAT_HOME/common/endorsed or check the variable JAVA_ENDORSED_DIRS in the Tomcat startup script. Some Tomcat’s versions use only this directory as endorsed.Snjeza
Dani,
Tomcat 5.5 uses common/endorsed as ‘endorsed’ directory.
What version do you use?
Can you check if you copy libraries to common/lib or common/endorsed (these directories already exist in the Tomcat distribution; common/endorsed is empty).Snjeza
Found it, when I add the jar files as external jar, for some reasons they are deployed in the WEB-inf/lib directory. If I remove the files after deployment, the code works fine. How can I tell eclipse not to deploy these two files in WEB-INF/lib
How can I tell eclipse not to deploy these two files in WEB-INF/lib
Deployment customization options are detailed in the Advanced section our
Working with Web Projects quickstart. You can configure the deployment at the workspace or project level so you should be able to cut it down to what you need.Snjeza,
I don’t want the external jar to be exported to the WEB-INF/lib. Can’t see a button for this. Maybe I could add the lib to a dependent project to solve the problem
regards
Dani
Dani,
The easiest way to do that is putting the external libs out of WebRoot directory and adding them to Project Build Path.
Regards
The jar files are not in the Eclipse Project Webroot directory (workspace/myproject/WebContent/WEB-INF/lib). The two jar files are added as external jar files to the project build path.
The problem is that the deploy mechanism copies the files into the tomcat WEB-INF/lib directory automatically from the external-jar reference in the project build path 🙁
Dani,
take a look at the preferences dialog:
MyEclipse/J2EE Project/WebProject on the tab Deployment in the group of checkboxes
called Library Deployment Policies and uncheck all of them.If you do this, you’ll have to copy the nescessary jars to the app server yourself,
but at your problem should go away.best regards

Manfred,
Thanks for the follow up! You’re exactly right all this is configurable as you mentioned. More detail is provided here:
https://www.genuitec.com/forums/topic/closed-tomcat-5-5-deployment-from-myeclipse/#post-262313Manfred, thanks for you help. I finally fixed the problem. I changed the configuration as you told me. Configured that way, I don’t have to manually deploy the jar files.
The jar files required for deployment are in workspace/projectname/WebContent/WEB-INF/lib directory. The javamail jars (activation.jar and mail.jar) are copied to /opt/tomcat/common/lib and added to the buildpath with properties->java build-path->libraries. If I deploy the project, only the files from workspace/projectname/WebContent/WEB-INF/lib are deployed.
