    Red face problems with jasperreports-3.0.0 and jdk 1.3.1_11


    in which jdk version should be run jasperreport 1.3.???

    I have a project that uses jasperreports-3.0.0 to show a file in .pdf format. The aplication server is SAP_J2EEngine6.20 and the jdk version is 1.3.1_11

    when i run the class that use jassperreport it shows the next message:

    java.lang.UnsupportedClassVersionError: net/sf/jasperreports/engine/JRDataSource (Unsupported major.minor version 48.0)
    at java.lang.ClassLoader.defineClass0(Native Method)
    at java.lang.ClassLoader.defineClass( :488)
    at .java:243)
    at$100(URLClassLoader. java:51)
    at$ 190)
    at Method)

    So when I runs it in jdk version is 1.6. it runs ok, but I need to work with jdk version 1.3.1_11, because in SAP_J2EEngine6.20, Versions different to the 1.3.1 are not supported, regardless of the OS and JVM Vendor.

    please can somebody help me.

    You'd probably have to use an older version of jasperreports then.
    P.S Even 1.4 is now considered old and has reached its eol.
