Working with IBM Websphere 8.5.5 on Linux, in my case CentOS,  I ran into an issue where the Websphere Customization Toolbox did not start.
Trying to use the console command to start it ( /opt/IBM/WebSphere/Toolbox/WCT/wct.sh ) did not provide any further information about the problem.

So lets have a look into the recent logs

#tail /var/logs/messages

Which showed some warnings... :  [ warning] [Gtk] Unable to locate theme engine in module_path: "clearlooks"

One suggestion to address this issue is to install gtk2-engines in a 32bit version, so lets try that....

# yum install gtk2-engines.i686

The next attempt to start the Toolkit brought more details, this time with a reference to a log file


Looking into this log file ( /root/.ibm/WebSphere/workspaces/WCT85/.metadata/.log  ) revealed a missing library.

java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons:
        /root/.ibm/WebSphere/configurations/WCT85/org.eclipse.osgi/bundles/45/1/.cp/libswt-pi-gtk-3659.so (libXtst.so.6: cannot open shared object file: No such file or directory)

Solution
Bottom line, the solution was to install those two packages

• # yum install gtk2-engines.i686
• # yum install libXtst.i686

Finally the Customization Toolbox started up and is working fine..
