war on servlets 4

[deneb shah]

hi
sorry to post this question buti havent still found ananswer to it. i am new to websphere
1- made a directory c:\websphere\appserver\deneb
2- had a servelt FirstServlet.java
3- compiled it in dos prompt to FirstServlet.class
4- with the assembly tool made a war in it
5- then made the ear with the same tool
6- installed the application ear file with the help of the administrative tool
7- saved the config
8- restarted the appserver
9- started the ibmwebserver
10- tried to access but failed
i thinkin the error i get a message ClassnotFound . this means the servlet could not be found.
i can send the ear file that i made. couls someone help me out
thnx alot

Post the error and the web.xml file that is in your war file -- the rest is binary (and not that much use). If you want to post the source code of your servlet, that might help too.

[deneb shah]

hey folks !!!
i am happy that i got a soln on my own
i have a jsp Hello.jsp and a servelet FirstServlet.class
web.xml
the url pattern for the servlet is -- /demopage
application.xml
the context for the application is -- demo
now to access
jsp --> http://127.0.0.1/demo/Hello.jsp
servlet --> http://127.0.0.1:9080/demo/demopage --- ???
i didnt understand why one would require port 9080 to be used for servlet.. could anyone give me a reason ???
also one more thing...
when installing the application from the AAT there are 3 textboxes
1-- path for the ear file
2-- name
3-- context root
i didnt understand the reaon for the 3rd textbox
could someone please answer these questions ???

[Kyle Brown]

Port 9080 is the one used by the appliation server. Port 80 is the one used by the web server to pass requests on to the appliation server. You should NEVER have to use port 9080. I strongly suspect that your problem is that you have not regenerated the plugin configuration file.
See the earlier posting (http://www.javaranch.com/ubb/Forum46/HTML/000503.html) where I told another reader that they need to run the GenPluginCfg batch file. This file (when given the appropriate information at the command line) will update the plugin so that you can use Port 80.

hey thnx buddy
u r a genius !!! but honestly i didnt understand why do u need the plugin after the deployment.
one more thing
the ear is an application server file. when one types http://hosts/appname its the webserver that redirects it to the corresponding thing. how an where is this mapping done
for eg when we have app server then we write a virtual host such that the webserver understands and picks up the appropriate file and then forwards it to the servelt/jsp engine. how does it work in here

[Kyle Brown]

The plugin configuration file (plugin-cfg.xml) contains the mappings for the context roots for the application that WebSphere uses. Take a look at the contents of this file and you'll understand how it works. Also, be sure to read the documentation on this subject (search for "plugin").
