example of using a server side bean or classe from inside a servlet...
Any examples or help is appreciated.

Hi.
I'm also fairly new to Java, but I think I may be able to help. I have used
server side beans in servlets before by importing them into my class and
instantiating them, then using their methods. Just like you would use java.util.*
in your code include for example com.serverbean.bean.* and use it's methods,
properties and events. The bean needs to be installed in a directory that
is in you CLASSPATH too. That is what I have done and it seems to work ok
for me. I hope this is what you were wanting out of a response.

Just to be sure I understand this, in your example, I would have a folde=
r=20
structure of:
<classpath>\com\serverbean\bean
and under this would be .class files (beans)
Or would it be:
<classpath>\com\serverbean
and bean.class is in the folder named above?

Re: How to use a class/bean from a servlet?
Yeah, in my example your bean would exist under the directory structure <classpath>\com\serverbean\bean\.
For example <classpath>\com\serverbean\bean\yourbean.class. The * just means
import everything in that package directory. If you write your own bean
then you can use whatever directory structure that you want for the file.
Otherwise you would use the bean developer's package information.
You can also check out this link: http://java.sun.com/products/jdk/1.2...ngclasses.html
and it will tell you more than you could possibly want to know about classes.
