How to log remote access

[ejain]

How does one log remote access to session beans (timestamp, bean, method, user, host)?

Currently I have to look up the user from context.getCallerPrincipal().getName() each time I write a log statement (log4j), no idea how to determine the remote host. But surely there is a more elegant (and efficient) way to accomplish this basic task?

The log interceptor already does some
basic call logging when enabled.

http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/jboss/jboss/src/main/org/jboss/ejb/plugins/LogInterceptor.java?rev=HEAD&content-type=text/vnd.viewcvs-markup

You could always write your own interceptor to perform
the logging required.

Second question,
java.rmi.server.RemoteServer.getClientHost()
this assume all requests use JRMP.

hi, I have the same problem.

I have added java.rmi.server.RemoteServer.getClientHost()
call to LogInterceptor, and all seems to work fine, but only if I call EJB session bean method (I use logging for this purpose) from stand alone client. When I access the same bean from .jsp page I get error ServerNotActiveException.

So in what way should I get ClientHost in that case.

Thanks for any help.

The only way to do this across different protocols
is to write a client interceptor (JBoss3 only).

The client interceptor can retrieve the client host
name (probably during static initialisation)
and then add it to every invocation object sent.

invocation.setValue("ClientHost", hostName);

The server's log interceptor can then retrieve it.
String client = (String) mi.getValue("ClientHost");

Again, this will only work when the client is a java
client. A c++ corba client cannot run the client
interceptor.
Also, this will show the server hostname when accessed
through JSP.

Thank a lot, seens it could work from one side, from another its not as simple I thought it could be.
I'll try to write that client interceptor, and hopes it will not tak much time and will work.

Maybe somebody has another idea?

Anyway thanks again,
