Hey, I’m new to Web Services, and having trouble when add another method to a web services.

I create a Web Services project first and then create a new Web Services,
It generated 2 class, named: checkCertificationImpl.java and IcheckCertification.java then I deploy it to Tomcat Server, it works well

Later I add another method to the Web Services, both in the interface and the implement class, and redeploy, hic, and it send me an error

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

Here is the source code of the WS, it’s very simple, just for testing,



import java.sql.ResultSet;
import java.util.ArrayList;


//Generated by MyEclipse

public interface IcheckCertification {
    public ArrayList testArrayList();
    public ResultSet ViewCertDetails(String certNo);
    
    
}

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.util.ArrayList;
import java.util.Date;



//Generated by MyEclipse

public class checkCertificationImpl implements IcheckCertification {
    
    public ArrayList testArrayList()
    {
        ArrayList a = new ArrayList();
//        a.add("hello");
//        Date today = new Date("20-10-1995");
//        a.add(today);
        return a;
    }
    
    public ResultSet ViewCertDetails(String certNo) {

        
        ResultSet rs=null;        
        return rs;
        
    }
    
}

And here is 2 .xml file
services.xml


<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xfire.codehaus.org/config/1.0">

    <service>
        <name>checkCertification</name>
        <serviceClass>IcheckCertification</serviceClass>
        <implementationClass>
            checkCertificationImpl
        </implementationClass>
        <style>wrapped</style>
        <use>literal</use>
        <scope>application</scope>
    </service></beans>

web.xml

Please help

Hi
You can’t return “untyped” collections. If you are using java5 then use e.g. ArrayList<String> syntax , if not, then use aegis mapping file to specify collection type.
You can’t also return different types of object inside collection like String and Date in your case.

Thanks,
I use String[] instead and it worked.

Greetings:

I am using XFire, EJB and Hibernate.

I am accessing this ejb from a web service project…

In the ejb project…
I have an EJB bean class named RegistrarEr.java.
Also, I’ve an Hibernate dataobject named RegistrationEr.java too..

This data object has another data object like the following in it..

public abstract class AbstractRegistrationEr implements java.io.Serializable {

private ChallengeQuestion challengeQuestion;

}

I am creating a binding file for this dataobject , using
RegistrationEr.aegis.xml as follows

When I start the server after deploying it, Iam getting the following
error..
Any Idea..??

ERROR [XFireServlet] Error initializing XFireServlet.

org.springframework.beans.factory.BeanCreationException: Error creating bean
with name ‘org.codehaus.xfire.spring.ServiceBean#1′ defined in class path
resource [META-INF/xfire/services.xml]: Initialization of bean failed;
nested exception is org.codehaus.xfire.XFireRuntimeException: Error
evaluating xpath /mappings/mapping[@uri=’
http://interfaces.session.selfserv.vrs.com’%5D. Nested exception is

org/jdom/Text: org/jdom/Text

org.jdom.JDOMException: java.lang.NoClassDefFoundError: org/jdom/Text:
org/jdom/Text

If I remove the RegistrationEr.aegis.xml file, the server starts up without
any error..But, throws the following error, when I try to access the WSDL…

org.codehaus.xfire.XFireRuntimeException: Couldn’t create type for property
challengeQuestion on class

Nested exception is org.jdom.JDOMException: java.lang.NoClassDefFoundError:

Any Idea..??

Thanks,
-Ganesh.

you need to add jdom.jar to your classpath

Thanks for your reply..
I’ve already added the jdom.jar to the class path of the Web services project..
I guess, the real problem is something else..
I tried adding the jdom.jar to the EJB project too..
Still its not working…

Make sure you have jdom in correct version 🙂

Thanks..
I’m using jdom-1.0.jar, which comes with myEclipse….I guess, its the right one…
Any other idea..??

Maybe its classloader problem. EJB module uses separate CL, so maybe try to put xfire libraries in same place visible by everyone ( server share library folder or something like )

I had same problem — and it’s the ArrayList return type of your method: http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-16539.html
