Hi All,

I have a brand new installation of MQWF 3.4 and webclient on Solaris 8.
WAS 4.0,DB2 7.2, MQ 5.2.

I logged on webclient and while running the sample processes, evrything is fine, am able to execute activities , but the instance monitor is not working.
It's giving out the following error.


Error: java.lang.NoClassDefFoundError

This is what I found on IBM site

For Solaris, if you are installing WAS 4.0x using XTerm, stop. You must do it native.

The DISPLAY must point to an X11 server, preferably (for performance reasons) the local host. The command is:

export DISPLAY=<my machine>:0.0

As an alternative, you can also run the virtual X server, for example:

/usr/X11R6/bin/Xvfb -aduti 2 :0 -screen 0 1600x1200x24

and then set DISPLAY=0:0 for the Web Client.

Set the DISPLAY variable either in the WebSphere Application Server startup script, in the profile of the user who starts the WebSphere Application Server, or in the shell where WebSphere Application Server gets started.

You should set DISPLAY variable in your WAS.

If you are using WAS4.0, you can set it using admin consol or wscp

See this link for more information.

Vennela,

Can you please elaborate on how to set the DISPLAY variable in WAS.
We have MQWF 3.4, Solaris 8.

I have tried one of the options listed in the links,

And the problem is we dont an X11 server running in the network.
Is it a necessity to have the X11 server or is there a workaround for this?

And also the DISPLAY variable , shud be set to point to the WAS server.Is that right ?

Thanks
Devin

I haven't used WAS4.0 in an year so I don't remember the wscp command. But using admin console
Nodes -> Hostname of the computer -> click on Application Servers
On the right hand side you will see General tab where there is an Environment section.
If you click on that you will get a name value pair of columns where you can set the environment variables.
In the name column enter DISPLAY
In the value column enter <hostname where WAS is running>:0.0

I am not sure about this part

you have to have an X11 Server on the box that runs the Web Client Web
Application. This is a requirement of the Java Development Kit if Java2D is
used for graphics creation.
