I am trying to deep-copy a complex data type.  To that end I
implemented clone() for all the types involved and I am having problems
with generics.  It's much harder to explain than to show, thus let me
show a silly example which demonstrates it:

I need to alter a servlet in J2EE I need to know if eveything is setup
correctly. Can anyone follow me through this.
Please help.

I have been using jserv with Apache 1.3 quite successfully.

"java.lang.NullPointerException" server error!!! The servlet, incidentally,
is one that is supposed to render a image. I have no idea of what ...

OK, I've got an object that needs to load a native DLL. So, I put the
System.loadLibrary(...) call in the constructor for that object. This
object is called from three different JSPs that instantiate the object.
When I run the JSP for the first time, I get the following error

and I couldn't compile those because they had SkipPageException,
which was not in my compile-time classpath.
