Web services stub generation + android

Question

I want to generate a android(java) based STUB for accessing all the web services. I have tried generating the stub using following tools:

1) Sun Java (TM) Wireless Toolkit 2.5.2_01 for CLDC,

2) ksoap2-generating-stub-0.1-SNAPSHOT-J2me-Android.

But i was unable to generate a proper stub that can be used. Please suggest any library or tool that you have used for the purpose.

thanks!!

Anyone here!!

Update:

Problem with sun java lib: There are some java libs that are not supported by Android. For eg: "javax.microedition.xml.rpc.Operation" etc.

Problem with ksoap2: getting a null pointer exception with following log in command prompt:

command that i run using windows command prompt:

java -cp ksoap2-generating-stub-0.1-SNAPSHOT-jar-with-
dependencies.jar;"%JAVA_HOME%\lib\tools.jar"
ksoap2.generator.Wsdl2Android -w "http://localhost:8080/Ws2Ksoap/
services/HelloWorld?wsdl" -g .\generated

As soon as i am running this code,i am getting following exception:

Exception in thread "main" java.lang.NullPointerException
        at ksoap2.generator.WsCompiler.compile(WsCompiler.java:86)
        at ksoap2.generator.WsCompiler.run(WsCompiler.java:78)
        at ksoap2.generator.Wsdl2J2me.run(Wsdl2J2me.java:116)
        at ksoap2.generator.Wsdl2Android.main(Wsdl2Android.java:41) 

Another Update: The created web services must not use any instance of java.rmi.* package.

Answer 1

have you included the ksoap2 jar file to your project ...? I had done and example of webservice using ksoap2 and got it successfully. I had used and online web service of www.w3schools.com, the details of the web service are as follows....

soap_action = "http://tempuri.org/CelsiusToFahrenheit"; method_name = "CelsiusToFahrenheit"; namespace = "http://tempuri.org/"; url = "http://www.w3schools.com/webservices/tempconvert.asmx";

hope this will help you.Good Luck

Answer 2

This exception occurred because you run java from JRE, but it searches for a compiler and can't find it. Use java.exe from JDK, like this:

"c:\Program Files\Java\jdk1.6.0_20\bin\java.exe" -cp ksoap2-generating-stub-0.1-SNAPSHOT-jar-with-dependencies.jar;"%JAVA_HOME%\lib\tools.jar" ksoap2.generator.Wsdl2Android -w "http://address/Service.svc?wsdl" -g .\generated

Answer 3

There is http://easywsdl.com generator. It uses ksoap2 library and supports complex types (with inheritance), data in attributes, header values and WCF extensions like Guid data type and data contract with IsReference attribute.
