DESCRIPTION:
With all the attention being paid to Ruby and it's hip cousin Rails, many in the Java camp may be feeling like their party invitation is lost in the mail. Fear not loyal Java lovers, the dynamic language meme is alive and well in your space! Between numerous JSRs and various languages, the JVM is becoming quite the dynamic disco. After an overview of what it means to be dynamic, this talk will look at JRuby, Groovy, and Rhino.

SPEAKER:
Nathaniel T. Schutta is a senior software engineer in the Twin Cities area of Minnesota with extensive experience developing Java Enterprise Edition–based Web applications. He graduated from St. John's University (MN) with a degree in Computer Science and has a master's of science degree in software engineering from the University of Minnesota. For the last several years, he has focused on user interface design. A long-time member of the Association for Computing Machinery's Computer-Human Interaction Special Interest Group, Nathaniel believes that if the user can't figure out your application, then you've done something wrong.

Along with his user interface work, Nathaniel is the co-creator of the open-source Taconite framework, has contributed to two corporate Java frameworks, has developed training material, and has led several study groups. During the brief moments of warm weather found in his home state of Minnesota, he spends as much time on the golf course as his wife will tolerate. He's currently exploring Ruby, Rails, and (after recently making the switch) Mac OS X. Nathaniel is the coauthor of the bestselling book, Foundations of Ajax.

Nathaniel is a No Fluff Just Stuff speaker.

Hi everyone,
I need some help. We are experiencing JAXB Exception while Marshalling. Here are the steps we did:
 ;

1.  Downloaded JWSDP2.0 pack, which contains Jaxb2.0&nbsp; and am added the jars (jaxb1-impl.jar,jaxb-api.jar,jaxb-impl.jar,jaxb-xjc.jar) into class path.

2. &nbsp;Ran Jaxb Schemangen.bat against java file (Settings.java bean) ;for generating XSD file. ;

3.  After XSD generated, then I ran xjc.bat (Jaxb compiler) against this XSD file.

4.  Then it has generated two files:&nbsp; ObjectFactory.java and Settings.java in generated folder.

5.  Configured Jaxb2Marshaller in applicationContext.&nbsp; File attached with this mail.

6.  Then I ran into two exceptions one after the other

 &nbsp; &nbsp;  i.  java.lang.NoClassDefFoundError: javax.activation.DataSource&nbsp;  - I have added Activation.jar into class path to resolve this problem.

 &nbsp; &nbsp; ii. java.lang.NoClassDefFoundError: javax.xml.stream.XMLStreamException - I have added jsr173_1.0_api.jar into class path to resolve this problem.

 

7.  Now I am getting the following exception when it calls marshall method.

 &nbsp; &nbsp;  org.springframework.oxm.jaxb.JaxbSystemException : Settings nor any of its super class is known to this context; nested exception is

 &nbsp; &nbsp;  javax.xml.bind.JAXBException: Settings nor any of its super class is known to this context

 

We would be very happy if you can provide any clues/suggestions for resolving this error.

 

Thanks,

Mohan
