An Unexpected Error Occurred Caused By Exception Unsupportedclassversionerror

serialVersionUID is a magic variable name. Because the compiler cannot analyse methods called through reflection, the reflection runtime wraps any errors thrown in the called routines in a predictable exception called the InvocationTargetException which you can catch.

Unable to open file xxx.exe Fatal error (0): Unable to open file xxx.exe In JET (Just Enough Time) when compiling, you forgot to terminate execution of your app before redoing the If you have been playing games with class loaders, the problem can be that you are using the wrong classloader to load some particular class. use javac.exe *.java to compile and java.exe com.mydomain.mypackage.MyClass to run. You only find out when you actually go to use that missing class. http://stackoverflow.com/questions/10830597/exception-in-play-framework

illegal nonvirtual Illegal use of nonvirtual function call An inner class is not permitted to call private methods of the enclosing outer class. Make sure you compile using the server's JRE and then try again. Don’t leap to conclusions about which one caused the trouble. You must copy mail.jar to the ext directory or mention the mail.jar in the manifest Class-Path: entry.

You can bump it up to either 1024 or 2048 with: // increase limit of Diffie-Hellman key size to 1024 or 2048 System.setProperty( "jdk.tls.ephemeralDHKeySize", "2048" ); This is the problem with Any references to non-serializable classes must be marked transient. You don’t have all the certificates you need in your cacerts. You could have no classes on it for a more advanced JVM than you are using.

Make sure you spelled all the jar names correctly and they actually exist on the download site in the directory you expected. The problem is caused by some sort of clash with code from one version interacting with code from another.

If you are getting the Exception on a System.loadLibrary( mylib ) try using System.load(C:\\libs\\mylib.dll) instead of the System.loadLibrary(mylib). Class myClass not found in new.

If every program gives NoClassDefFoundErrors, try uninstalling all Java tools and JDK s, clean out the registry and then reinstall.

It's important to understand that this is different than ClassNotFoundException which comes while trying to load a class at run-time only and the name was provided during runtime, not at compile-time. You might be tempted to count on ClassCastExceptions to filter out nulls for you. The womb won’t be smart enough to do that on its own and you will get all manner of NoClassDefFoundErrors. You must cast it to the class of the Object or one of its superclasses.

i am getting while trying to run emca (oracle). This exception happens when you cast a generic reference to an Object to an invalid class. While you are at it, give each of those classes Oracle’s JDK Platform Guide to NotSerializableException : available:on the web at Oracle.comin the current JDK 1.8.0_102 on your local Windows J: http://crearesiteweb.net/an-unexpected/an-unexpected-error.html Then the other apps may stop working.

Reinstall the JDK with associated JRE, making sure you select a drive explicitly for each of the three pieces, the JDK, the database and the JRE. StreamCorruptedException StreamCorruptedException The object stream is scrambled. we put all source files in C:\Program Files\Java\jdk1.6.0\bin folder that is all java files. Delete any DLL in VCP\BIN that also exists is VCP\JAVA\BIN.

The definitions and references to a class differ in whether they include some field. The Applet will then work on one website only, or locally only. Make sure you used semicolons or colons as appropriate. An the app works fine locally but fails when you deploy it on a server because you failed to upload all the class files needed to the server (usually in jar

You overrodeJPanel.getParent or perhaps some other crucial piece of Oracle’s code without reproducing its functionality typically by calling super.xxx(). It is similar to a ClassNotFoundException. class file contains wrong class class file contains wrong class. November 8, 2011 at 2:55 AM Anonymous said...

In JDK 1.4.2+, the compiler should detect the problem rather than runtime. At least for debugging, move your loadLibrary call out of static init so you can catch the Exception and see the stack trace more easily and debug trace more easily. If you have source for the libraries, recompile everything to discover the precise error. security violation No error while developing.
