    Maybe you give a little more details. What app you are programming? What JDK are you using? ....

    Hello Neelan,

    the messages you posted contain several references to Java 1.1 - which is much too old to run anything from NetWeaver 7.0.

    I assume you've somehow "uncovered" the old Java RE from Windows (which happens to be a 1.1 JRE, before Microsoft and Sun started their dispute about Microsoft-specific Java extensions).

    Please check the value of the JAVA_HOME environment variable, and check the list of installed Java RE's / SDK's in the NetWeaver Development Studio.

    Best regards, Christian

    I agree with Christian.

    The reason you get the error is that Xbootclasspath is a non-standard option and probably was not part of the first java versions.

    You tried to start your app with a JVM version 1.1.8_010.

    Iu2019m very surprised that you have java version 1.1, which was released in February 1997.

    The minimum required version is 1.4.2.

    • Hello Ventsi,

      I somehow remember that MicroSoft shipped an 1.1 Java RE with some Windows versions, and I guess that JRE is still lingering around in the world.

      Best regards, Christian
