I didn't see right away that you were trying to invoke the 64bit version JAVA 1.4. I found this APAR on IBMLINK: PK24855
ERROR DESCRIPTION: java -version when running J9VM displays the following message: JVMJ9VM023I This may indicate that JAVA_HOME is incorrect, or that class libraries are not installed. JVMJ9VM015W Initialization error for library jclscar_23(14): JVMJ9VM009E J9VMDll Main failed Could not create the Java virtual machine. LOCAL FIX: Increase your REGION size. That is, when logon to the tso/e logon screen on the size parameter: e.g. SIZE=2000000 I tried it on y asnd-box LPAR and I got this error: Could not create JAVA virtual machine. (And I have a 512M reagion size) Take a look at their LOCAL fix... It looks like a 2 gig region size to me !!! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
