Hello,

i am trying to call one servlet from another servlet. The two servlet belong to different applications but deployed on the same tomcat.

Can someone tell me what is the best way to do that?


Thanks a lot

ServletContext.getContext(String uripath) can get a reference to another servlet context, and from there you can access resources in that context such as Servlets. There are a few things to keep in mind:

1) Depending on the container, you will need to look at the documentation to see if you need configuration settings to allow this. By default it is not allowed.
2) Communication with the other Servlet may be via another Thread, so the the data may not arrive as you expect.
3) cross context communication is typically poorly implemented in containers, and is poorly defined in the spec.
