Connecting to a different host..........

843811

Hi guys, well I have this problem, I have an JApplet that's a RMI client in the machine A and my RMI server is in the B machine, so I get security exceptions like these:

Client exception: checkconnect.networkhost1

sun.applet.AppletSecurityException: checkconnect.networkhost1
at sun.applet.AppletSecurity.checkConnect(AppletSecurity.java:576)
at sun.applet.AppletSecurity.checkConnect(AppletSecurity.java:618)
at sun.applet.AppletSecurity.checkConnect(AppletSecurity.java:518)
at sun.rmi.transport.proxy.AsyncConnector.<init>(RMIMasterSocketFactory.java:321)
at sun.rmi.transport.proxy.RMIMasterSocketFactory.createSocket(RMIMasterSocketFactory.java:128)
at sun.rmi.transport.tcp.TCPChannel.openSocket(TCPChannel.java:279)
at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:150)
at sun.rmi.transport.tcp.TCPChannel.newConnection(TCPChannel.java:123)
at sun.rmi.server.UnicastRef.newCall(UnicastRef.java:67)

I tried using policy files to grant socket permissions but it didn't work. I update the java.security file for the JRE adding the path where the policy lies and nothing, I'm still getting this awful exception.

This is the policy file:
---------------------------------------
keystore "file:d:/proys/mysecurity/userstore";

grant codeBase "file:d:/resin2.0.1/doc" {
permission java.net.SocketPermission "*:1024-65535", "accept, connect, listen, resolve";
};
---------------------------------------

What can I do? Do you know some way to workaround this?

Any help will be appreciated.

Notes: I'm using JDK1.3 and the Java Plugin 1.1.3, Netscape 4.61

Hi Qaorisq,


If you are using the Java plugin, you should not get this type of security error. Whether you can able to get Java plugin console. whether this error message is generated out of ordinary browser console or java plugin console.

Also please check this URL for configuring swings with browser.

I hope this will help you.

Thanks

Hi,
I had the same situation as you. I have a stand-alone RMI client application. After the client got the reference to the remote server object, it called the method of the remote server object. Then this security exception was generated:
*** Security Exception: checkConnect:To xxx.xxxxxxxx.com ***
java.rmi.RMISecurityException: security.checkConnect: To xxx.xxxxxxxx.com
at java.lang.Throwable.<init>(Compiled Code)
at java.lang.Exception.<init>(Compiled Code)
at java.lang.RuntimeException.<init>(Compiled Code)
at java.lang.SecurityException.<init>(Compiled Code)

at sun.rmi.transport.tcp.TCPChannel.newConnection(Compiled Code)

Did you find the reason? here is my email adress:

Your applet must be signed before it can access resources not on the host which it was launched from.
