I'm new to the list, and to Web Services (in a grad class for it), so let me
first say howdy!
I'm getting error when trying to run some client code. I'm using two types
of clients, one using the low level API's and one that uses the stub code
generated with WSDL2Java. My current environment is:
Java 1.4.1 SDK
J2EE 1.3.1 SDK
Axis 1.0
Tomcat 4.0.4
Ant 1.5
My web service interface is as follows:
import data.Ad ;
public interface AdWS
{
public boolean placeAd( Ad ad ) ;
public Ad[] searchAds( Ad ad ) ;
}
My deploy.wsdd looks like:
<deployment
xmlns="http://xml.apache.org/axis/wsdd/";
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java";>
<service name="AdWebService" provider="java:RPC">
<parameter name="className" value="AdWSImpl"/>
<parameter name="allowedMethods" value="placeAd"/>
<beanMapping
qname="AdNS:Ad"
xmlns:AdNS="urn:AdWS"
languageSpecificType="java:Ad"/>
</service>
</deployment>
My build.xml has the following for generating my stubs:
<target name="ad.stubs">
<java classname="org.apache.axis.wsdl.WSDL2Java" fork="yes">
<arg value="-o"/>
<arg value="."/>
<arg value="./conf/AdWebService.wsdl"/>
<classpath>
<path refid="axis.libraries"/>
</classpath>
</java>
</target>
The service deploys fine without errors. My client code utilizing the API's
looks like:
import org.apache.axis.AxisFault;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;
import org.apache.axis.utils.Options;
import javax.xml.namespace.QName;
import javax.xml.rpc.ParameterMode;
import data.Ad ;
public class LowClient
{
public static void main(String [] args) throws Exception
{
String[][] keys = { {"Seller","Jason Adam"},
{"State","CO"},
{"Breed","Appaloosa"},
{"Name","Pearl"},
{"Price","N/A"},
{"Ad","Test AD"}
};
Options options = new Options(args);
Service service = new Service();
Call call = (Call) service.createCall();
Ad ad = new Ad();
ad.setCategory( "Horse" );
ad.setKeywords( keys );
QName qn = new QName( "urn:AdWS", "Ad" );
call.registerTypeMapping(Ad.class, qn,
new
org.apache.axis.encoding.ser.BeanSerializerFactory(Ad.class, qn),
new
org.apache.axis.encoding.ser.BeanDeserializerFactory(Ad.class, qn));
try {
call.setTargetEndpointAddress( new
java.net.URL(options.getURL()) );
call.setOperationName( new QName("AdWebService", "placeAd")
);
call.addParameter( "arg1", qn, ParameterMode.IN );
call.setReturnClass( Boolean.class );
call.setReturnType( qn , Boolean.class );
boolean ret = ( (Boolean)call.invoke( new Object [] { ad })
).booleanValue();
System.out.println("Result : " + ret);
} catch (AxisFault fault) {
System.out.println( "Error : " + fault.toString());
}
}
}
If I use this client, I get the following error:
lowclient.run:
[java] Error : org.xml.sax.SAXException: Deserializing parameter
'arg1':
could not find deserializer for type {urn:AdWS}Ad
My client using the stub stuff is:
public class Client
{
public static void main(String [] args) throws Exception
{
System.out.println( "Test" );
System.out.println( "In Client" );
String[][] keys = { {"Seller","Jason Adam"},
{"State","CO"},
{"Breed","Appaloosa"},
{"Name","Pearl"},
{"Price","N/A"},
{"Ad","Test AD"}
};
System.out.println( "Creating locator" );
localhost.AdWSImplServiceLocator locator =
new localhost.AdWSImplServiceLocator();
System.out.println( "Locator received: " + locator );
localhost.AdWSImpl aws =locator.getAdWebService();
System.out.println( "AWS received: " + aws );
data.Ad ad = new data.Ad();
ad.setCategory("Horse");
ad.setKeywords( keys );
System.out.println( "Ad created and set" );
boolean result = aws.placeAd( ad );
System.out.println( "Ad placed" );
if( result )
{
System.out.println( "Success!" );
}
else
{
System.out.println( "Failure" );
}
}
}
And I get the following error using that client:
client.run:

[java] AWS received: localhost.AdWebServiceSoapBindingStub@b48197

The errors look like the same issue is occuring, though I'm not sure why one
generates a different format for the data type that can't be deserialized.
Any ideas where the problem is occuring? Any help is appreciated, and I
apologize for all the extra code and stuff, wanted to make sure I presented
everything that may be of value. Let me know if you need some other info.
Thanks!
Jason
