infiniumpro — Thu, 14 Oct 2010 09:39:34 +0000

I have a customer that is receiving a Java dump several times per day on their Test system but does not occur on the Production system. I know nothing about Java of the JDM. I can submit any part or all of the dump, but not sure what you would need. I am including the TITLE, GPINFO and ENVINO portions.

Any assistance on helping with this would be greatly appreciated. :

JVM problem: Not able to run the Java Program but it’s getting compiled

NEWJAVA — Sat, 11 Sep 2010 11:37:02 +0000

i have a problem of running java programs…
When i try to run the java programs i get like this
Exception in thread “main” java.lang.UnsupportedClassVersionError: H (Unsupported major.minor version 50.0)
        at java.lang.ClassLoader.defineClass0(Native Method)
        at java.lang.ClassLoader.defineClass(Unknown Source)
        at java.security.SecureClassLoader.defineClass(Unknown Source)
        at java.net.URLClassLoader.defineClass(Unknown Source)
        at java.net.URLClassLoader.access$100(Unknown Source)
        at java.net.URLClassLoader$1.run(Unknown Source)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(Unknown Source)
        at java.lang.ClassLoader.loadClass(Unknown Source)

        at java.lang.ClassLoader.loadClass(Unknown Source)
        at java.lang.ClassLoader.loadClassInternal(Unknown Source)
I try to find out the solution for this but i didnt succeed
UnsupportedClassversionError means that older version of jvm is accessing the higher version of java .i.e., the native method of old JVM is not comaptable with the newer version.
In command prompt i had find the version is

java version “1.4.2_03″
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_03-b02)
Java HotSpot(TM) Client VM (build 1.4.2_03-b02, mixed mode)
but i have installed JDK 1.6 version

I try to find whether the JVM is there or not in my computer by typing the command
JVIEW
but it is not there by saying not recognised.
I updated the Java version with the latest one from java website but still the same above problem persists to me
please find out the solutuion to me and reply to my mail
