    Hi,
    I'm going back to doing some JAVA now but have moved to a new version
    of Xcode since my last mxj forays. I'm using Xcode 2.2 on 10.4.4.
    When I open the HelloWorld project and hit build, I get the following
    error:
    command .Developer/Private/jam failed with exit code 1
    cd "/Applications/MaxMSP 4.5/java-doc/ide/Xcode/HelloWorld"
    setenv ASCII_OUTPUT_ANNOTATION YES
    setenv ENABLE_APPLE_JAM_EXTENSIONS YES
    setenv ENABLE_APPLE_JAM_OUTPUT_ANNOTATION YES
    setenv GROUP wesleysmith
    setenv NATIVE_ARCH ppc
    setenv USER wesleysmith

    Anyone else get this? Solutions?
    thanks,

      hi,
      the HelloWorld project example project that comes with the max-
      package is still using the old Xcode project path structure.
      so, using:
      cp build/Development/classes/*.class "/Library/Application Support/
      Cycling '74/java/classes"
      instead of:
      cp build/classes/*.class "/Library/Application Support/Cycling '74/
      java/classes"
      as a "Run Script" to automatically move your compiled class to the
      cycling folder solved the problem for me.
      you might want to try it and see if it solves you problem.
      bye,
      volker.

      Thanks,
      That worked, but now I can't load it in the mxj object. I get these error:
      • error: java.lang.UnsupportedClassVersionError: HelloWorld (Unsupported major.minor version 49.0)
      • error: at java.lang.ClassLoader.defineClass0(Native Method)
      • error: at java.lang.ClassLoader.defineClass(ClassLoader.java:539)
      • error: at com.cycling74.max.MXJClassLoaderImpl.doLoadClass(MXJClassLoa derImpl.java:119)
      • error: at com.cycling74.max.MXJClassLoader.loadClazz(MXJClassLoader.ja va:88)
      • error: Could not load class 'HelloWorld'
      I just changed to JAVA 1.5. Would this be causing problems?
      thanks,
      wese

      So, To answer my own question. Yes, that was the problem. I just
      rememered an old thread about changing the JVM preferences in a text
      file somewhere. Will look into that.
      thanks,
