Hi,

I have an GWT application working perfectly currently. Say it as "APP1".The context path of APP1 is /APP1. Now I am introducing a new link into that application. Clicking on the new link will call home page of another GWT application, say "APP2". The context path of APP2 was different form APP1. The context path of APP2 is /APP2.

Can any one help me how to access the web application that was resided in different context path and how to forward the some data to second web application? I'm thinking it can be just a html href link with request data appended in the url...any clue?

Thanks,
 
Sheriff

That would be my guess, too. Web sites routinely include links to other web sites, after all. What happened when you tried it?

You could try with <cross-context> in your web.xml to inform the web container this web application is ready to send request to other resources(web applications). For examples with explanations: (I've not tried out this way)

I would make app1 send an HTTP request to app2 using a library like Jakart HTTP client.
If you use a GET meaning appending data to url you will be limited in the amount of data you can send,
you dont have this limitation with a POST that's why it's my preferred option.
I hope that will help
