Installing programs built with Java

Question

I have a client who installed programs [applications] we built in Java. One person has no problem installing and running the programs. Another can install and run two of the three programs. The third program does not open a dialog box for them to register the program with us. The third person can open one program [the second installs with the first but will not open]; and the third program does not install at all. They all use Windows 2000 5.00.2195 with Service Pack 3. For the program that will not install the task manager indicates that 100% cpu processing time is involved. For the other programs that will not run, they get the javaw.exe error message. A fourth person with Service Pack 4 cannot install any of the programs and gets the wjview.exe generated error and the computer shuts down. This represents money to us if we can solve this problem. I would appreciate any help or suggestions.
Thanks

Answer 1

* You ship your own JRE for your app
* You get errors from wjview.exe
Based on these 2 evidences, your app is not launched
with your shipped JRE correctly. Perhaps it is
launching the default java and not the full path to
your JRE location? That is at least one of your
problem you need to fix there.
I suggest two probabilities
1) As lichudang says above, launching is not correct. wjview.exe is a component of MS Java, not Sun Java.
2) Possibly these client machines have acquired spyware/adware/viruses. Using wjview to launch these buggers is somewhat common.
Take a look at this thread http://forum.java.sun.com/wireless/thread.jsp?forum=8&thread=351762&start=30&range=15&tstart=0&trange=15 which talks about (2) above.
This Google search turns up quite a few references, try refining it with additional terms
