How do I get kXML to work?

Question

I'm trying to implement an existing XML parser: kXML.

I ran into the following error:

java.lang.NoClassDefFoundError: org/xmlpull/v1/XmlPullParserException
 at com.sun.midp.midlet.MIDletState.createMIDlet(+29)
 at com.sun.midp.midlet.Scheduler.schedule(+52)
 at com.sun.midp.main.Main.runLocalClass(+28)
 at com.sun.midp.main.Main.main(+80)
Execution completed.

At this site you can find the error that I ran in to. The solution however doesn't work. I used the following script:

C:\WTK2.5.2_01\bin\preverify -classpath .;C:\java_libraries\wirelesstoolkit\midpapi20.jar org.kxml2.io.KXmlParser
C:\WTK2.5.2_01\bin\preverify -classpath .;C:\java_libraries\wirelesstoolkit\midpapi20.jar org.kxml2.io.KXmlSerializer
C:\WTK2.5.2_01\bin\preverify -classpath .;C:\java_libraries\wirelesstoolkit\midpapi20.jar org.xmlpull.v1.XmlPullParser
C:\WTK2.5.2_01\bin\preverify -classpath .;C:\java_libraries\wirelesstoolkit\midpapi20.jar org.xmlpull.v1.XmlPullParserException
C:\WTK2.5.2_01\bin\preverify -classpath .;C:\java_libraries\wirelesstoolkit\midpapi20.jar org.xmlpull.v1.XmlPullParserFactory
C:\WTK2.5.2_01\bin\preverify -classpath .;C:\java_libraries\wirelesstoolkit\midpapi20.jar org.xmlpull.v1.XmlSerializer

cd output

C:\Program Files\Java\jdk1.6.0_14\bin\jar -cvf ..\kxml2.jar org

I get the following errors (mutliple of these):

C:\Users\****\Desktop\kxmlfolder>C:\WTK2.5.2_01\bin\preverify -classpath .;C:\
java_libraries\wirelesstoolkit\midpapi20.jar org.kxml2.io.KXmlParser
Error preverifying class org.xmlpull.v1.XmlPullParser
    java/lang/NoClassDefFoundError: java/lang/Object

C:\Users\****\Desktop\kxmlfolder>C:\WTK2.5.2_01\bin\preverify -classpath .;C:\
java_libraries\wirelesstoolkit\midpapi20.jar org.kxml2.io.KXmlSerializer
Error preverifying class org.xmlpull.v1.XmlSerializer
    java/lang/NoClassDefFoundError: java/lang/Object

What can be the cause?

Answer 1

You problem is that you managed to configure your development environment to compile your MIDlet against the kXML libraries but your didn't include them into your MIDlet jar file so the J2ME emulator doesn't know how to find the classes your MIDlet imports at runtime.

Answer 2

Maybe you should include the kXml library. if you use eclipse MTJ, just right click on the project name, select properties, select Java Build Path in the list, in the right click select libraries, add external jar button, browse and select the kXml.jar file. You will see the new library now included. Try run the project again.
