nested webapps in tomcat?

Currently, we have the following webapp:

webapp1/
--META-INF/
--WEB-INF/
----web.xml
----lib/

This webapp is very simple, has no front end, a very basic web.xml, and executes lots of code within the jar files in WEB-INF/lib.

We have developed a separate webapp that does have a front end, uses struts, tons of tag libraries, etc and looks like:

webapp2/
--images/
--jsp
--script
--style
--META-INF/
--WEB-INF/
----web.xml
----struts-config.xml
----a ton of tld's
----lib/

The issue we ran into is that webapp1 now needs to initialize, launch and interact with webapp2. However, because webapp2 has a very different configuration and should be somewhat modular, we don't want to just combine the two.

question: is it possible, in tomcat 5.5, to make the following directory structure work:

webapp1/
--META-INF/
--WEB-INF/
----web.xml
----lib/
----webapp2/
------images/
------jsp
------script
------style
------META-INF/
------WEB-INF/
--------web.xml
--------struts-config.xml
--------a ton of tld's
--------lib/

that is, webapp2 is contained within the WEB-INF folder of webapp1 but each webapp still has its own web.xml, WEB-INF/, META-INF, etc.
 
No, that is not possible. Each web app must be self-contained.

What level of interaction do you need between webapp1 and webapp2?
 
I believe there's a way in tomcat to allow apps to interact with one another, although for a life of me I can't remember how. You may need to look up tomcat documentation.

That being said, I would recommend against that, since it goes against everything in J2EE spec. Did you consider having APP 1 expose the needed functionality through web services?

Click to expand...

that's a shame... there's no way to do it, not even using struts?

we have a relatively large amount of interaction between the webapps... webapp1 starts and stops many parts of webapp2 and they need to share a number of objects between them.

i've read online of ways to share data between webapps, but so far, none of them look like "clean" and "safe" approaches, so I think we'd rather avoid them. in the absolute worst case, we'll collapse the two webapps together, but if any1 has other suggestions, please share them!
