    ERROR: class file has wrong version 50.0, should be 49.0

    853473
      Dear All,

      I am having a J2EE application running on Java 5.
      Now I have a requirement to use the different appliaction libraries (jar files).

      After using the different appliaction library in my application, I am getting this error:
      *********************
      cannot access com.test.service.IConnection
      ERROR: bad class file: D:<complete path for file>/service/IConnection.class)
      [javac] ERROR: class file has wrong version 50.0, should be 49.0
      [javac] ERROR: Please remove or make sure it appears in the correct subdirectory of the classpath.
      [javac] ERROR: import com.test.service.IConnection;
      *********************

      I understand that there is mis-match in the Java versions used in my application and the other application where Jars are created.

      Please suggest me how can I proceed (I cannot change my Java version as it is a requirement for one of my server.).

      Regards,
      Patana
