First I am not a java developer,but I need some help determining an issue I am having. I am running a java application built by a vendor of mine, which works on about half of my machines and bombs out on the other half. My systems are mostly xp machines and I have tried multiple version of java. Most of my machines are running the latest version now (6-31), and we use IE 7. 

ERROR: null
    java.lang.reflect.InvocationTargetException
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)

  • can you provide more details? when does the exception occur is it during compile or after running? what type of application is it? – Asaf Feb 15 '12 at 20:08

    An `InvocationTargetException` is a wrapper which means some *other* exception happened. That other exception is the one that will have useful information, not the one you posted. You should check your log to see if you have another inner exception underneath the one you posted. – Kirk Woll Feb 15 '12 at 20:08
  • I researched about this exception i am able to run my application on some of the machines but not on all...i have this exception...and i think i read it somewhere does it have to do with the OS installed or other softwares like IE which can create problem for this – zain Feb 15 '12 at 20:10
  • Well, that's quite little information. Is there more in the stack trace? The error seems to indicate something is null (or only the exception message is null) but it's hard to tell what could cause this without having more context (for example the full stacktrace etc). Btw, is this a client/server application? If so, are the machines you're talking about the servers or the clients (IE 7 would indicate a client)? – Thomas Feb 15 '12 at 20:13
