jar Archive and Servlets

[Nick Lebian]

Hi!
Is it possible to run my Servlet, whose classes are in a jar archive (including the class with the doPost method)? If yes, how have I to configure the web.xml file (I'm using tomcat)?
Thanks,
Nick

Why don't you:
(1) Create a WAR file for your project (in whatever way your IDE provides for that purpose) and
(2) Deploy that WAR file to Tomcat in whatever way is appropriate for that servlet engine?

Hi Nick,
Regardless of how you deploy your web app (war file or not), if the jar file containing the servlet is placed within the WEB-INF/lib folder of your web app, it will be in the classpath of the app.
In your web.xml you would create servlet and servlet mapping declarations as approriate. Or is it the format of these declarations that has you stumped? If that's the case, here's a simple example lifted from one of my web.xml files:

<servlet>
<servlet-name>LoggingManager</servlet-name>
<servlet-class>com.some.packages.logging.LoggingManager</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>LoggingManager</servlet-name>
<url-pattern>/logging/*</url-pattern>
</servlet-mapping>

This is just one way to deal with a servlet. Your needs may vary. Point is, the entries in the web.xml are orthogonal to whether your servlet is in a jar or not, as long as it is in the classpath.
hth,

P.S. One of the bartenders is soon going to ask you to change your name, as "Nick Someone" does not conform to Ranch policies. Why not do them a favor and beat them to the punch?

Thanks for your response. But I think i still don't understand it. I have a jar File named "mypackage.jar". I deploy it in the web-inf/lib folder. What have I to change now in the web.xml file, if the class which shall be mapped to a URI is in this jar-File?

Whats wrong with my nick? ;-)

No changes. It will "just work"

And yah, the official "change your name" request. Please.

[Nick Lebian]

It doesn't work. There only comes this error message:
java.lang.IllegalArgumentException: Not an HTTP URL:java.io.IOException: HTTP response code: 500

[Bear Bibeault]

Sounds like your URL is malformed.
Further responses will be available when your name is changed to conform to Ranch standards. Not to be a bully, but you have now been officially asked.
