I'm running Windows 7 and Juno. JDK 1.7, GVT 2.4, App Engine 1.7
I did a stockwtro tutorial and everything worked great then I put it in an app engine. Everything still worked great!
However, I did the RPC portion of the tutorial. When I ran away locally, I got a Java met. Verify that I have fixed the thread due to the following (in the default VM arguments in the fixed -XX: -VSSplitVerifier). It then worked locally and I posted in app engine.
In the app engine, I get a java.lang.UpsupportedClassVersionError. I get two threads which are similar problems, and I'm using a fresh installation of windows 7 and the only JDK I downloaded was 1.7. Look through Eclipse, I see JR7, JDK 1.7 and App Engine 1.7.
I have read somewhere that the app engine does not work with 1.7. However, the app engine SDK version 1.7 is on the download page (I think it may be super recent), but in reality I do not know whether these things are related. I went ahead and downloaded Java 6 and api engine SDK 1.6.6, JR installed on JR 6, set compiler compliance level to 1.6, he also changed my project to a good measure, and the default app Engine changed SDK to 1.6 6.
Now I'm getting the error, "Java compiler level does not match the version of the Java Project Initiative installed." I triggered this problem and everyone asks to right click on the project and change the aspect, but I can not find that option. I do not even know that I am going right about this. If possible, I want to use the most recent versions of everything I do not even understand that the app engine has worked with RPC for the first time but broke it from RPC.
Any help would be greatly appreciated !!! GAE currently does not support Java 1.7, only 1.5 and 1.6 are supported.
The relevant paragraph is low:
App Engine runs Java application using Java 6 virtual machine (JVM). App Engine supports SDK Java 5 and beyond, and Java 6 can be compiled using Java compiler classes with any version of JVM JAVA compiler.
The version of GAE SDK you downloaded does not belong in any way with the Java version (1.7).
