    We have few applications(WAR files) that remotely connect to middle
    layer on some other server. The middle layer is a set of EJBs. Now we
    are supposed to have common services which access these middle layer
    EJBs remotely and return appropriate objects. These common services
    will be used by different web applications in the front-end and reside
    on the same clustered server on which the web applications are there.

    Web applications--->common services(?)--->middle layer(EJBs)
    --->Backend

    Now the question is What should these common services be

    1. EJBs - good solution but performance drawback because middle layer
    is already EJBs and web has to go thru 2 layers of EJBs
    2. Normal java classes but then they have to be included in every web
    applications and then changing these will result in all applications
    being changed and rebuilt.
    3. Web services - Is it a good option here, because web application
    and common services are on the same server.

    Any other possible solution? Please give your suggestions and
    comments.

    Thanks
