Generate JAXB Classes - cannot find XJCFacade [message #662010]

I'm attempting to generate JAXB classes from an XSD. When I right-click the schema and select the Generate->JAXB Classes, I get the following error on the console.

java.lang.NoClassDefFoundError: com/sun/tools/xjc/XJCFacade
Caused by: java.lang.ClassNotFoundException: com.sun.tools.xjc.XJCFacade
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
at java.security.AccessController.doPrivileged(Native Method)

at java.lang.ClassLoader.loadClass(ClassLoader.java:307)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301 )
at java.lang.ClassLoader.loadClass(ClassLoader.java:248)

I've been digging through Eclipse docs for better part of a day now, and cannot find anything that suggests that I need to do anything special to Generate JAXB Classes.

Config:
Version: Helios Service Release 2 Java EE version.
Build id: 20110218-0911

EclipseLink SDK 2.2.0 (not sure if I need this or not)

JDK 1.6.0_24

Can someone point me to docs that explain where XJCFacade is and how to install it into eclipse?

Thanks
Michael

BTW, I do see com.sun.tools.internal.xjc.XJCFacade.class in JDK 1.6 tools.jar.

Is there a better newsgroup to post this issue?

Hi Michael,

The JAXB tooling is provided through the Dali project. Here is a link to their forum:

I had the same problem.

I changed my jdk to 1.7 and the problem went away.

Hello

You have to use the JDK as runtime for your project in eclipse

It work well with JDK 1.6 but not with JRE6

regards

I recently migrated from one machine to another and updated from Kepler Release to Kepler SR1. I am unsure which of these steps made my Java Library change from JDK to JRE during this process... anyway, the hint in this thread is very helpful. As it took me quite some time to google it with a German error message (and it also seems it slightly changed because I only got one single line), I'll just add my (localized) error-message here, as I didn't find the reason for JAXB-generation failing which previously worked, until I got here. So may an early google hit help others, too. Smile

Fehler: Hauptklasse com.sun.tools.internal.xjc.XJCFacade konnte nicht gefunden oder geladen werden

Freely translated:

Error: Main class com.sun.tools.internal.xjc.XJCFacade could not be found or loaded.

Changing the Java library from JRE to the JDK in the project settings worked fine. (after adding the JDK to the workspace in the Eclipse settings)

Your Project is pointing to JRE , not to JDK .
Update JRE Home directory with JDK Home directory.

Because JDK 1.6 or 1.7 onwards xjc.jar will be bundled along with JDK.

I updated my project with the jdk1.8.0_91, but still get the same error message. xjc.jar is not contained in my jdk.
Was it removed with 1.8? What do I need to install then?

Like Amogh said, you just need to use a JDK instead of a JRE.

It is funny to see previous reply about JRE when the guy is saying he is using JDK...

"- I am using a JDK 1.8
- You are using JRE. You must use a JDK for your project."

Yeah right... Thanks for that...
