Need suggestion on exposing the Jar file.

[ram kumar]

Dear Ranchers,

I need some suggestions,

Scenario
I have a jar file with 5 API's with input parameters and return types.

API 1 takes int as input parameter and return array of bytes.

All other API's return int as return type.

Problem Case :
Now, my problem is, this jar with all 5 api's should be exposed as single unit accessible by different systems.

It should be able to resolve all http based calls.

Either from a dot net system or from a j2ee server.

What can i use for that.

#1.servlet (If i use servlets how do they return byte arrays and integers. servlets say public void doPost())

#2.RMI

#3.TCP/IP

Need your valid suggestions on this








Thanks.

Looks like a candidate for Web Services. Expose your API through Web Services, you could try Axis Java to deploy your APIs as Web Services and use a relevant Web Services client from the client platform you want to use.

Or with modern application servers it shouldn't difficult to deploy your APIs as a Web Service.

Hope this helps.

Thanks first !

We discussed to deploy the jar as EJB(Stateless session Beans) and deploy that as web services.

Every API becomes an EJB method that exposesitself with return values and input parameters.

so that all http request from .net and j2ee systems are served.

Any other Suggestions - Welcome !

Also,

I hope the AXIS java tool is a deployer tool that deploys j2ee components as Web-Services.

Why dont we implement it using servlets ? Is it not possible ?

I hope it is not possible, since servlets cannot return any that API methods return.

They are basically public void doPost().

please clarify !
