JSPM GUI does not work properly on UNIX. Other terms
Java Support Package Manager; JSPM; remote GUI; UNIX; X-Windows Reason and Prerequisites
When JSPM is started it automatically starts its GUI on the local machine, i.e. the machine JSPM is running on. If the SAP system is on UNIX and a Windows PC is used as a client, which is quite common, this requires some kind of X server software to run on the Windows PC in order to display JSPM GUI. Solution
The only software of this kind in use at SAP, and therefore the only one which has been tested extensively in this scenario, is Hummingbird Exceed. Other X servers (like XMing) can not be guaranteed to work flawlessly. In this case the whole eventing mechanism of Java Swing is not transported properly back and forth between XMing and the Java VM, leading to an apparently unresponsive GUI.
While some customers are able to run JSPM GUI in X-Windows on UNIX systems, this setup has not been validated by SAP and is not guaranteed to work.
