hello all, I was happily developing my code in eclipse3.1 and also executed it many times. But suddenly i got this error: Exception in thread "main" java.lang.UnsupportedClassVersionError: Indexer1 (Unsupported major.minor version 49.0) at java.lang.ClassLoader.defineClass0(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:539) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:123)...............

Eclipse is running with JDK 1.4, but you're trying to load a class file compiled with default settings under JDK 1.5. That's not going to work. Either run Eclipse with JDK 1.5, or don't use any classes or libraries compiled with 1.5 unless you use the --source 1.4 switch.
