javax.servlet.jsp.JspTagException: ClassNotFoundException Error
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hay TomCatters,
I have some really wired behaviour on my Tomcat 3.2.1 Installation.
We have some classes laying around in the deployment classes folder:
$TOMCAT_HOME/webapps/APPNAME/WEB-INF/classes/
1.) The classes are physically there.
2.) The classpath is build properly and included on startup. (see
$1)
and I get the ClassNotFoundException :(((
the Class is loaded dynamically with:
Beans.instantiate(classLoader, "com.eproduction.ResourceProvider");
So My question (for hours now)....
...where to put the class so that the classLoader can allocate it? I
have no (more) clue?
ok. There is a workaround. I can put those classes under:
$TOMCAT_HOME/classes
then the whole thing works. But this is exactly not what I wanted. I
want to pack the application and keep those helper classes in the
application's classes folder under WEB-INF.
Any suggestions?
thx.
