My understanding is that it is.
Dynamic downloading of classes is a choice, but when bind/rebind rmi.server.codebase is to be set.
I verified this - took this property off and exceptions were thrown. There are reasons why it should be like that, but still I have a feeling that if not specified when bind/rebind, the classpath should be considered as codebase.

-V

Megha,
Note the exception - anything and everything is not related to classpath.

Patwa..,
I don't understand what tname embed within Jdk is and you can see that I am not using CORBA. It is simple java:
rmiRegistry = Runtime.getRuntime().exec("rmiregistry "+rmiPort);Naming.rebind(url,object);

anybody?

Extending is very common - like below:
//An example of using an anonymous inner class. public class MyClass extends Applet { ... someObject.addMouseListener(new MouseAdapter() { public void mouseClicked(MouseEvent e) { ...//Event listener implementation goes here... } }); ... } }
How about implementing?

My thanks to somebody who can shoot this; I am stuck.

Note that the rmi registry has started successfully; still Naming.rebind() fails to connect. Is it because the rmiregistry 1099 starts at hostname and localhost doesn't resolve to it?

Say, a web application is added to a few already existing ones, in an engine of Tomcat supposed to run on a host. This web application makes a RMI call and needs to run with a RMISecurityManager.

If <catalina.home>/bin/startup -security is run with ./catalina.bat edited to specify -Djava.security.manager=java.rmi.RMISecurityManager all the other web applications too will run with that - perhaps not good! The question is, how to enable a Security Manager per web application? Things may be similiar but lets' talk about Tomcat 5.

Thanks. -V

Thank You for the reply.

What I am asking is this - Can it be closed between transactions by the setTransactionIsolation()? Will it always throw an exception, is it a bad practice or is it okay to do that?

I understand that the isolation level of a connection can not be changed when a transaction is in progress, but can it be changed between two transactions?

Let me ask this Q with an example:
I run my Class A from d:\product\scripts. In A I want to do a Runtime.getRuntime().exec("a.bat"); a.bat is in d:\product. So is there a way I can specify the dir. location of the Process that I get by doing a Runtime.getRuntime() - in this case as d:\product - meaning run a.bat @ d:\product.
Interestingly, I expected that there'll be an overloaded exec(), which let's me specify the dir. location.

hi all,
Consider, for e.g, the class org.apache.xerces.dom.DeferredTextImpl is present in both xmlx.jar and a01_topllink3.6.3.toplinkall.jar; if I were to use classpath I would mention the xmlx.jar before the a01_topllink3.6.3.toplinkall.jar and have the class picked from that; but if it's a web application deployed as a WAR in Weblogic6.1, and both these jars are at WEB-INF/lib inside the WAR, how to specify the order ?
I tried specifying the order in META-INF/Manifest.mf and warring it too, along with the rest of the application.
It's impending for me to find a solution to it, so plz treat it on a priority basis.

hi,
If I redirect to a URL, I achieve a GET. How to achieve a POST ?

Can anybody tell me, why is this happening ?

Regards,
vishal.

Return an appropriate ActionForward object that identifies the JSP page to be used to generate this response, based on the newly updated beans. Typically, you will acquire a reference to such an object by calling findForward() on either the ActionMapping object you received (if you are using a logical name local to this mapping), or on the controller servlet itself (if you are using a logical name global to the application).

- struts-documentation\userGuide\building_controller.html
Please explain what's being meant by using a logical name local to this mapping vs if you are using a logical name global to the application.
