    Hi
    I just downloaded and installed myeclipse ide 5.5 M1 (all in one build), i am still using java 1.4.2 for development so i changed my java version to 1.4.2_13 in Window – Preferences – Java – Installed JREs from the default C:\Program Files\MyEclipse 5.5 M1

    Then i created a sample java project, now this java project uses j2sdk1.42 , and wrote a simple test class to print Hello World!!
    When i try to run this class i get java.lang.UnsupportedClassVersionError: com/ashishk/test/TestClass (Unsupported major.minor version 49.0) error, it seems that this program is compiled with j2sdk1.4.2 but trying to run with java 5.0 or vise versa.
    When i use the change the jre to myeclipse jre it is able to run java program without error

    Here is the error message i get when i run the program using java -verbose

    When i try to run this class i get java.lang.UnsupportedClassVersionError: com/ashishk/test/TestClass (Unsupported major.minor version 49.0) error, it seems that this program is compiled with j2sdk1.4.2 but trying to run with java 5.0 or vise versa.

    Actually, it can only be vice versa. The class is compiled with jdk 1.5 but you’re trying to run it with 1.4.2. That’s why the major.minor is unsupported. If it were compiled with jdk 1.4 but run on 1.5 it would work since 1.5 is backward compatible.

    I’d ensure that the default compiler settings as well as your project’s compiler settings are set to 1.4.2. Additionally, when you create the launch configuration to run your application, be sure to specify that it should be run with 1.4.2 as well.
