Jclient and ias

Question

I made a local jclient application with bc4j (no ejb) which works fine, now I want to deploy the bc4j (ejb) things to ias. this works too
but now every time i try to compile the jclient project, jdeveloper makes some jar files of the bc4j components (this takes some minutes). Is this necessary?
By the making of the ias deployment , jdev also make a application module client file ( i have some client methods). If i try to use this client file in my jclient file it gives an exception. How do i implement this client methods in my jclient project.
the behavior of the jclient appl. is totally different in local mode and ias mode. I am getting errors like record modified by other user. Is there a whitepaper on this topic.
Do i need an ias for jclient apps or can I run it on a several machine without the need of an ias/oc4j like the way you run it inside jdeveloper.
thanks,
edwin

necessary?When you build a client project for an application in 3 tier mode by default a dependency is setup betwen the client project and the common profile of the middle tier project. The common profile is used to generated the jar containing the files required by the client. Every time you compile the client project this jar is regenerated. As an alternative you can manage this dependency yourself:
In the client project settings dialog uncheck the common profile dependency. Instead add a new library to the client project which points to the jar produced by the common profile.

jclient file it gives an exception. How do i
implement this client methods in my jclient project.The client file is a proxy that implements the interface containing the exported appmodule methods. The class in internally instantiated by the framework. You should be able to call yor methods by casting the apmodule reference to the custom appmodule interface. See the OnlineOrders\BatchClient sample.

What kind of exceptions? Can you elaborate.

a several machine without the need of an ias/oc4j

You don't need to deploy the ejb (actually the .ear file containing the ejb) to an ias instance. You can either use the embedded oc4j instance or the external standalone instance. Make sure to use the right config in the JClient application. I don't have the help system handy but I believe these topics are covered in the doc.
