Hello,
I have a android webservice client application. I am trying to use the java standard WS library support. I have stripped the application down to the minimum, as shown below, to try and isolate the issue. Below is the applicaiton,
package fau.edu.cse;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class ClassMap extends Activity {
TextView displayObject;
@Override
public void onCreate(Bundle savedInstanceState) {
// Build Screen Display String
String screenString = "Program Started\n\n";
// Set up the display
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
displayObject = (TextView)findViewById(R.id.TextView01);
screenString = screenString + "Inflate Disaplay\n\n";
try {
// Set up Soap Service
TempConvertSoap service = new TempConvert().getTempConvertSoap();
// Successful Soap Object Build
screenString = screenString + "SOAP Object Correctly Build\n\n";
// Display Response
displayObject.setText(screenString);
}
catch(Throwable e){
e.printStackTrace();
displayObject.setText(screenString +"Try Error...\n" + e.toString());
}
}
}
The classes tempConvert and tempConvertSoap are in the package fau.edu.cse. I have included the java SE javax libraries in the java build pasth. When the android application tries to create the "service" object I get a "java.lang.noclassdeffounderror" exception. The two classes tempConvertSoap and TempConvet() are generated by wsimport. I am also using several libraries from javax.jws.. and javax.xml.ws.. Of course the application compiles without error and loads correctly. I know the application is running becouse my "try/catch" routine is successfully catching the error and printing it out. Here is what is in the logcat says (notice that it cannot find TempConvert),

...bla...bla...bla
It would be great if someone just had an answer, however I am looking at debug strategies. I have taken this same application and created a standard java client application and it works fine -- of course with all of the android stuff taken out. What would be a good debug strategy? What methods and techniques would you recommend I try and isolate the problem? I am thinking that there is some sort of Dalvik VM incompatibility that is causing the TempConvert class not to load. TempConvert is an interface class that references a lot of very tricky webservice attributes. Any help with debug strategies would be gladly appreciated.
Thanks for the help,
Steve
