Java Development Tools

The error message doesn't tell anything about the problem.

Don't you see anything else in the log?

Instead of deploying the app directly to the integrated server, can you deploy it to an ear file?

Have you tried to start the application?

Timo

How would an Android app be tested on WebLogic Server? Doesn't an Android app have to packaged into an .apk and tested on an emulator or Android device?

Hi again! I appreciate your help but could you elaborate on how I'd go about deploying the app to an ear file? As for if I tried to start the app, the tutorial advises not to do that because the app may not function properly.

From the log:

This seems to be issue of a.Service class being compiled on JDK 1.7 but you are trying to run it on JDK 1.6

Which version of JDK you are using in jdeveloper?

Which version of JDK is used by your weblogic?

Is a.Service coming from a library or its your own class in project?

Thanks

Sanjeev

Yes, I'm using JDK 1.7 for JDeveloper and JDK 1.6 for weblogic. In the beginning I was running into so many hurdles that I was willing to download anything I thought was necessary to get the emulator running.

a.Service comes from the SampleWS.zip file.

You can't deploy a 1.7 compiled file on 1.6. I believe you should change JDK of weblogic to move to 1.7 or start developing with 1.6 JDK in jdeveloper.

To change jdev's jdk version you can follow Mark's Blog: Change JDK used by JDeveloper

To change weblogic jdk version you can follow My work: Changing Weblogic Configuration to use newer version of JDK

Thanks

Hi, do you still have any more suggestions?

Caused By: java.lang.UnsupportedClassVersionError: a/Service : Unsupported major.minor version 51.0

"I gave it a try by using jdk160_24 for JDeveloper"

It is not the JDeveloper version which needs to be changed, but the JDeveloper Java Compiler version.

The Java version to use should be supported based on Oracle JDeveloper 11g Release 2 (11.1.2) Certification

JDeveloper 11.2.4 has some Java version related issues, use a different JDeveloper version preferrably, but if not please refer

Notes:

-JDK 7 supported added in 11.1.2.4.0.

• There is a known, serious issue with this version of JDeveloper running with Oracle JDK 1.7 Update 25. For more information, see the issue for JDK 1.7 Update 25 (16710919) in the release notes,
• JDeveloper bundles Integrated WLS 10.3.5, which does not support JDK 7. To use JDK 7 for JDeveloper and Integrated WLS, you can install WLS 10.3.6 separately and create an "Integrated Server" connection to it from JDeveloper.

-32 bit JDK required for profiling features.

-For JDK 6, update 39 or later is recommended; for JDK 7, update 10 or later is recommended

-On Mac OS 10.5 Java for Mac OS X 10.5 Update 8 or later is recommended, on Mac OS 10.6 Java for Mac OS X 10.6 Update 3 or later is recommended

Thank you for your help but there are still some tasks I can't do.

Is the Java version issue fixed?

The Java 6 update recommended is 39 while jdk160_24 is used.

"For JDK 6, update 39 or later is recommended"

What I tried to do was upgrade the WebLogic Server to 10.3.6 but I couldn't create an integrated server connection.

1. Shutdown JDeveloper

2. Delete the system directory C:\Documents and Settings\username\Application Data\JDeveloper\system11.1.1.x.x.xx.xx

The directory path could be slightly different.

3. Restart JDeveloper.
