Question

Java applet errors in IE only or without VPN

WC Gurus:

We have a strange problem occurring with the Windchill Java applets when using Internet Explorer (in our case IE7). If we access Windchill on our LAN, the Java applets only work in IE when we use Java 1.5. If we use 1.6 we get a Java access error in the console. But if we connect using the VPN, we can use IE and ANY Java version, 1.5 or 1.6.
In addition, we can use Firefox or Chrome on the LAN or on the VPN with ANY Java version. See the table below.
Has anyone else had a problem like this?

What are the failure symptoms, e.g. what shows up in the Java console?

Is this with or without RMI tunneling?

Also which MOR level are you at?

[Note 1.6u18 is out now and 1.6u13 is a bit old.]

We are on WC9.1 F000.



The attached file shows the Java console from trying to access Workflow Administrator. Other applets result in basically the same error, depending on the operation at hand:



wt.util.WTRuntimeException: The operation: "getObject" failed.

Nested exception is: wt.util.WTRemoteException: Unable to invoke remote method

Nested exception is: wt.util.WTRemoteException: Unable to locate method server

Nested exception is: wt.util.WTRemoteException: Unable to locate method server

Nested exception is: wt.util.WTRemoteException: Unable to get server

Nested exception is: java.security.AccessControlException: access denied (java.net.SocketPermission 10.1.1.55:5002 connect,resolve); nested exception is:





(BTW I tried 1.6u18 but did no further testing on it when 1.6u6, 1.6u7, 1.6u12, and 1.6u13 failed and 1.5u6 worked.)

From the error it would seem like in MSIE when connecting via the LAN,
the RMI address for Windchill is being resolved as 10.1.1.55 -- and that
this does not match where the applet believes it came from, thus causing
the communication to be rejected.

Why this address is being resolved this way in MSIE and apparently not
in Firefox is unclear.

[Note that there are plenty of good reasons, i.e. fixes, to move up to
the latest R9.1 MOR, currently M040, rather than sticking with F000,
though I don't have any firm reason to believe that this will help your
particular issue.]
