Jini problem : Error when creating a transaction

[SH4F33]

Hello everybody. Im currently learning java and jini. Im using jini version 2.1.
Ive been working on simple examples from books and I can read/write to the space. Im using only one computer,meaning that the jini services and the client are on the same computer.
I tried creating a transaction but I get the following error:

java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:4160 connect,resolve)

I thought that there was a problem with the policy file, but it seems OK. I even opened the port 4160 in my firewall but without any luck.

If I remove the code for creating the transaction, the program works fine;i.e, I can read/write to the space.

Is there something that I should add or remove?

Thanks in advance.

Can you post your policy ?

Thank you very much for your attention.

Here's wats in ther policy file:

grant {
    permission java.security.AllPermission;
};

The filename is jsk-all.policy. I just copied the one that jini is using and put it in my class folder ;p

JBuilder is launching my class with the following arguments:

D:\Borland\JBuilder2006\jdk1.5\bin\javaw -classpath "D:\bb\classes;

Have you tried editing the default policy under JAVA_HOME, or providing a full path, eg :

-Djava.security.policy=D:\full\path\to\jsk-all.policy bb.test

Since Im new to java, I dont know wat default policy is. I just copied the jsk-all.policy to the folder where all my classes are.

Ive also tried the following:

My classes are in c:\Java Projects\bb\classes\bb
And the policy file as well is in that same directory

Ive tried running the program with these VM arguments:

-Djava.security.policy=c:\Java Projects\bb\classes\bb\jsk-all.policy bb.test

-Djava.security.policy=c:\Java_Projects\bb\classes\bb\jsk-all.policy bb.test (I thought that the space in the directory name was the error)

-Djava.security.policy=jsk-all.policy bb.test

But again no luck.

Hi,

I have Steven Halter's Java Spaces Example by Example but it's for Jini 1.1 and having trouble getting example 1, finding a java space to work. Wondered which book(s) you might recommend that are useful for jini 2.1. Thanks.

Well, even if its for v1.1, u can still get the basics like read,readifexists and so on.

But I guess for the the space lookup service and the transaction manager lookup service, the code will b slightly different.

I can provide u the code for the lookups and a little exampe.
