Subject RE: Servlet error I can't seem to resolve
Date Wed, 27 Dec 2000 17:07:12 GMT
Hi, Simon.

 Why would you say that it's a bad idea to put .jar files in the
classpath?  In the case of commonly-used jars, like mail.jar for example, why
would it be better to replicate this in each application's WEB-INF/lib
directory?

Thanks,
-Jeff

Subject: RE: Servlet error I can't seem to resolve

The stack-trace seems pretty clear to me - the
"sendIt" method of the IridiumSendMail class is
storing a null pointer into a hashtable.

What you may find is that the IridiumSendMail
class is expecting to load a resource file from
somewhere, but not finding it because you
forgot to install it, or didn't install it in the
right place.

Just a note on the location of the "mail.jar"
and "activation.jar" files - I think that the
correct place for these is where you
first had them, in the WEB-INF/lib
directory within your web application.
Placing jars in the classpath is
generally a bad idea with tomcat
(though quite a lot of tomcat users
don't seem to understand this; presumably
they are the same ones that would be
using global variables under c++ :-)

regards,

Simon
