Subject RE: Setting the classpath for my application
Date Mon, 24 Jul 2006 19:06:41 GMT
I wanted to confirm that jar files in the WEB-INF/lib  directory were
included in the classpath for my application. In reading through the online
documentation for Tomcat I found the following:

"WebappX - A class loader is created for each web application that is
deployed in a single Tomcat 5 instance. All unpacked classes and resources
in the /WEB-INF/classes directory of your web application archive, plus
classes and resources in JAR files under the /WEB-INF/lib directory of your
web application archive, are made visible to the containing web application,
but to no others."

I am doing exactly this. My jar file (foo.jar) is in the
webapps/abc/WEB-INF/lib directory for my 'abc' application. However, in the
Catalina log file, when Tomcat starts, I get a "ClassNotFound -
com.abc.framework.ControlServlet" error. Why can my servlet not be found if
it resides in the jar under the WEB-INF/lib directory???

Any help would be appreciated.

Thanks,

Darren

Is the fact that I'm receiving a ClassNotFound error from Tomcat's
ClassLoader for a class that I've created indicative of a bad classpath?
Are jar files stored in WEB-INF/lib automatically included in Tomcat's
classpath for my application?

If so, how do I set the classpath for my application in Tomcat?

Thanks,

Darren

Subject: ClassNotFound - Is WEB-INF/lib in my app's classpath?

Ok, I've deployed my application in Tomcat 5.5 on Solaris using the war
deploy feature in the manager.

The application (lets call it 'foo') shows up in the manager as '/foo', so I
know that it deploys. When I look in catalina.log, I see a ClassNotFound
exception, alerting me that the ClassLoader wasn't able to find my
ControllerServlet class. Here is the error from Catalina.log:

2006-07-24 09:38:46,987 DEBUG
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/foo] -

----------> Parent Classloader:
org.apache.catalina.loader.StandardClassLoader@1c92535
 com.abc.framework.controller.ControlServlet
java.lang.ClassNotFoundException:
com.abc.framework.controller.ControlServlet

My ControlServlet class is located in this jar file
webapps/foo/WEB-INF/lib/abc.jar in the package
com.abc.framework.controller;.

Are the jar files in WEB-INF/lib included in my application's classpath by
default? Do I need to make a classpath change somewhere? Is the fact that
WEB-INF/lib not show up in the repositories listing above meaningful?

Why can't Tomcat's classloader find my ControlServlet class?

Thanks,

Darren
