Multiple EAR files

[Former Member]

Dear spammers,

1:

What if...

You have 2 EAR files and you are fooling around a bit with some Local and/or remote beans. (already read that local beans are not accessable from within another EAR file)

So the question is, is there a way to let multiple EAR files communicate with each other?

2:

What if you have a news module, agenda module and a profile module. Now you want to let them communicate with each other, which of the following can be used at best:

Beans, WebDynPro or J2EE WEB-APPS?

Thnx in advance,

Hi Kodde,

From your question, It looks to me that you are talking about communication between applications at behaviour layer.

You have an option of going to any kind of applications but need to create them as DC (Development Components). This methodology allows to reuse and also can call the behaviour among DCs. For example you can have a common custom Portal Service DC which can have methods for key operations. This DC can be made as Used DC to various DCs (Like J2EE DC, Webdynpro DC, Portal Application DC, etc).

In this way you can have a control at one point and can be instrumental to communicate the business behaviour.

If your question is of Front End Communication, Then it would be at iView level communication. This can be done by EPCM (Client Eventing), WDEventing (WebDynpro Eventing) or also can come up with your own communication mechanism.

So, It doesnt matter what you are using. But all that matter is how you are using the applications.

Hope this is useful., May be i havent addressed exactly what you are looking for. If this is the case., let us know exactly what you are looking for.

Thanks,

Thanks for your helpful answer.

DC projects sound a little complicated, so we're trying to share only the data between the applications, and not the source code.
