rmi

I'm using RMI to allow access to my Java application via MATLAB, which runs in another JVM. MATLAB has a nice interface to print the methods of a Java object. But it fails with RMI, because the object it gets is a proxy. So I would like to add my own method to extract/print the capability of a remote interface (RMI obviously can't directly access methods not available in exported remote interfaces). How could I do this with reflection, either on the client end of the RMI connection, or on the server end? I don't have much experience using reflection. Use case below. edit: what I'm getting most

I'd like to be able to restrict the ports used by my application to some small-as-possible known set. The application uses Java RMI to communicate with a remote server. The registry is exported on port 1099, which is standard. However, it appears that the port used to export the various remote objects is not always consistent, though it does stay the same across multiple connections over a short period of time. My uneducated guess is there is some sort of caching of the server sockets going on behind the scenes which causes this. I'd like to be able to ensure that the connection always occurs

How to programmatically grant AllPermissions to an RMI application without using policy file? UPDATE: After some researching, I have written this custom Policy Class and installed it via Policy.setPolicy(new MyPolicy()) . Now I get the following error: invalid permission: (java.io.FilePermission \C:\eclipse\plugins\org.eclipse.osgi_3.7.0.v20110613.jar read class MyPolicy extends Policy { @Override public PermissionCollection getPermissions(CodeSource codesource) { return (new AllPermission()).newPermissionCollection(); } } Based on @EJP 's advice, I have debugged using -Djava.security.debug

I have two web application, webAppMaster and webAppSlave , deployed in same tomcat server. Now in webAppMaster application, there is a java class, RequestHandler whose processRequest method takes a customObject1 as parameter and returns customObject2 . Now, from RequestCreator class of webAppSlave application, I want to invoke processRequest method of RequestHandler class of webAppMaster application. How this should be done ? Thanks in advance. walkeros You need to talk between applications as if you were talking between two distant applications. It does not matter that they are on the same

But we start up our Java process: - Dcom . sun . management . jmxremote - Dcom . sun . management . jmxremote . port = 6002 - Dcom . sun . management . jmxremote . authenticate = false - Dcom . sun . management . jmxremote . ssl = false I can telnet to the port, and "something is there" (that is, if I don't start the process, nothing answers, but if I do, it does), but I can not get JConsole to work filling in the IP and port. Seems like it

When you use RMI in Java the remote stack trace of an exception will be prepended when you receive it, somewhat like this: ERROR Client received error when doing stuff: myapp.FooBarException: bla at server.myMethod() at rmi.callHandler() // and now, on the next line comes the client at rmi.sendCall(); at client.doServerMethod() at Thread.run() How is that kind of stacktrace "forgery" done? What do I want it for (apart from just being iterested)? Well, it would help me if I could do this: outer() { thread = new Thread(... inner(); // inner() throws // RuntimeException // at inner(); // at
