[Axis2] Exception occurred while trying to invoke service method
Hello,
first of all, I apologize for my bad English...
I have a problem but I don't know how I can resolve it.
This is code:
--
PrintOnVideo.java
--
package stampa.wservice;
import stampa.data.Ordinabile;
public class PrintOnVideo{
public String print(Ordinabile o){
System.out.println("E' stato ricevuto un oggetti di classe
"+o.getClass().getName());
return (o.getClass().getName());
}
}
--
Ordinabile.java
--
package stampa.data;
public interface Ordinabile
{
public boolean maggioreDi(Ordinabile o);
}
---
PrintClient.java
---
package stampa.client;
import javax.xml.namespace.QName;
import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;
import stampa.data.Carte;
public class PrintClient {
public static void main(String[] args1) throws AxisFault {
RPCServiceClient serviceClient = new RPCServiceClient();
Options options = serviceClient.getOptions();
EndpointReference targetEPR = new EndpointReference("
http://localhost:8080/axis2/services/PrintOnVideo";);
options.setTo(targetEPR);
// Setting the weather
QName opPrint = new QName("http://wservice.stampa/xsd";, "print");
//setto l'oggetto
Carte obj = new Carte("Re","Nero","Fiori");
Object[] opPrintArgs = new Object[] { obj };
Class[] returnTypes = new Class[] { String.class };
Object[] risposta = serviceClient.invokeBlocking(opPrint,
opPrintArgs,returnTypes);
String cclasse = (String) risposta[0];
if (cclasse == null) {
System.out.println("Weather didn't initialize!");
return;
}
// Displaying the result
System.out.println("La risposta e' stata "+cclasse);
}
}
-
Carte.java
-
package stampa.data;
public class Carte implements Ordinabile{
private String valore, colore, seme;
public Carte(){
valore=new String("Asso");
colore=new String("Rosso");
seme=new String("Cuori");
}
public Carte(String val, String col, String sm){
this.valore=val;
this.colore=col;
this.seme=sm;
}
public boolean maggioreDi(Ordinabile o){
if (o instanceof Carte){
Carte p=(Carte)o;
boolean ok= seme.equals(p.getSeme());
if ( ok ){
int x= Integer.parseInt(valore);
int ox= Integer.parseInt(p.getValore());
return ( x>ox );
}else{return false;}
}else{return false;}
}
String getValore(){return valore;}
String getColore(){return colore;}
String getSeme(){return seme;}
}
When I run my client, I have this exception:

Re: [Axis2] Exception occurred while trying to invoke service method
Ah ... no, the spaces are not in my code, only in my mail there is a
space...
I modified my service with other method trying to understand what is the
problem, but some work and some not
package stampa.wservice;
import stampa.data.Ordinabile;
public class PrintOnVideo{
Ordinabile m;
public String print(Ordinabile o){
m=o;
//String r=new String(m.getClass().getName());
String r=new String("Questa [ la mia stramaledetta classe ...");
return (r);
}
public void setO(Ordinabile o){
m=o;}
public Ordinabile getO(){
return m;
}
public String stampami(){
return("Speriamo Speriamo Speriamo...");}
}
setO don't have exceptions, getO returns me a null object, stampami works
and print gives me this exception ...

Check the line where EndpointReference is constructed in your code.
You'll see that there is an extra space between " and http:. You can
also see it in some of the previous posts in this thread.

setParam0(OMElement param) or xs:any
Hello! (Sorry for my bad English...)
My problem is that my service is like this:
public Object[] compute(Object[] data){
//...
}
and MyServiceStub.Compute has setParam0(org.apache.axiom.om.OMElement[]
param) and get_return returns an OMElement[]...
I don't know how to create an OMElement within Object[] ...and viceversa.
Please, can you help me ?
Thank you very much!!!

Re: setParam0(OMElement param) or xs:any
Thank you for your answer, but I don't understand can you please do an
example?Do you mean that I have to change parameters ?
Thank you very very much!!!

2007/2/27, Deepal Jayasinghe <[EMAIL PROTECTED]>:
Hi ;
When you have a method which take Object then there is no way to find
out the type of that object. That is why it generates WSDL with xsd:any.
To solve that U need to write the method to take the method with correct
Object type (String [] or what ever).
Thanks

Re: setParam0(OMElement param) or xs:any
I need to pass a variable number of different objs...
I also tried to pass a Vector of Integer (for an example) but axis2
doesn't know how resolve it and it gives me a xs:any ...
I tried also to pass one my class, called Vettore (with an array of
Object or a Vector) but when I generate the stub, it contains an its
Vettore, different from mine...
I can't explain better...
Thank you for your attention!

Hi ;
I am talking about smt like below;
public Address[] compute(Man [] data){
//...
}
Do not use just Object ,use the actual type you want to use.
Thanks

Re: setParam0(OMElement param) or xs:any
Thank you for your answer! I suppose that BeanUtil's method goes only
with javabean obj, but I'll try to apply to my project ! (sorry for my
English)
Thank you, thank you very much

2007/2/28, Nilesh Ghorpade <[EMAIL PROTECTED]>:
Hi,
There is a utility tool in the AXIS 2 API's namely the BeanUtil I believe.
This class has some static methods which would enable you to convert from an
Object to an OMElement and vice versa.
Hope that helps.
Regards
Nilesh

Re: setParam0(OMElement param) or xs:any
I tried to use BeanUtil's method, but I had an error:
Exception in thread "main" java.lang.IllegalArgumentException: null rcl
at org.codehaus.jam.internal.reflect.ReflectClassBuilder.(
ReflectClassBuilder.java:47)
at org.codehaus.jam.provider.JamServiceFactoryImpl.createBuilder(
JamServiceFactoryImpl.java:173)

at org.apache.axis2.databinding.utils.BeanUtil.getPullParser(
BeanUtil.java:225)
at org.apache.ws.axis2.Client.main(Client.java:61)
The code is this:
...
OMElement[] param1=new OMElement[6];
Integer [] ve=new Integer[6];
ve[0]=(new Integer(12));
ve[1]=(new Integer(23));
ve[2]=(new Integer(34));
ve[3]=(new Integer(45));
ve[4]=(new Integer(56));
ve[5]=(new Integer(67));
for(int i=0;i<6;i++){
XMLStreamReader reader = BeanUtil.getPullParser(ve[i]);
StreamWrapper parser = new StreamWrapper(reader);
StAXOMBuilder stAXMOMBuilder =
OMXMLBuilderFactory.createStAXOMBuilder (OMAbstractFactory.getOMFactory
(),parser);
param1[i] = stAXMOMBuilder.getDocumentElement();
}
req2.setParam1(param1);
...
I suppose that the error is that, if I do
Integer a = new Integer(55);
ClassLoader cl = a.getClass().getClassLoader();
cl is null, and I don't know why!
Can you help me, please?
