Hi Toshi,
Exactly! I should use in wsdd file:
deserializer="org.apache.axis.encoding.ser.JAFDataHandlerDeserializerFactory
"
serializer="org.apache.axis.encoding.ser.JAFDataHandlerSerializerFactory"
instead of:
deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
After that, the example mentioned by me works.
BUT!!! I cannot display the WSDL for this service from now on
AXIS error
Sorry, something seems to have gone wrong... here are the details:
Fault - ; nested exception is:
WSDLException: faultCode=OTHER_ERROR: Can't find prefix for
'http://activation.javax'. Namespace prefixes must be set on the
Definition object using the addNamespace(...) method.:
AxisFault
faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException
faultSubcode:
faultString: WSDLException: faultCode=OTHER_ERROR: Can't find prefix
for 'http://activation.javax'. Namespace prefixes must be set on
the Definition object using the addNamespace(...) method.:
faultActor:
faultNode:
faultDetail:
I also updated to AXIS 1.1 final and I tried to remove typeMapping from my
wsdd. The example still works, but I still cannot get WSDL (the same error).
Jacek.
Hi Jacek,
Yes, you have a mistake about serializer's configuration.
If you're using AXIS 1.1 final, please try again with no
typeMapping on your wsdd. (i.e. You should re-deploy your
service, after you drop the typeMapping node on your wsdd.)
In case of any exceptions or using AXIS 1.1 earlier, please
try to add the right typeMapping for DataHandler by referring
to the following sample;
.........*.........*.........*.........*.........*.........*.........*
<deployment xmlns="http://xml.apache.org/axis/wsdd/";
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java";
xmlns:ns1="urn:EchoAttachmentsService" >
<service name="urn:EchoAttachmentsService" provider="java:RPC" >
<parameter name="className"
value="samples.attachments.EchoAttachmentsService"/>
<parameter name="allowedMethods" value="echo echoDir"/>
<operation name="echo" returnQName="returnqname"
returnType="ns1:DataHandler" >
<parameter name="dh" type="ns1:DataHandler"/>
</operation>
<typeMapping
deserializer="org.apache.axis.encoding.ser.JAFDataHandlerDeserializerFactory
"
languageSpecificType="java:javax.activation.DataHandler"
qname="ns1:DataHandler"
serializer="org.apache.axis.encoding.ser.JAFDataHandlerSerializerFactory"

Subject: Re: help required for attachment using ejb as webservice
Hi Toshi,
Thank you for the explanation. It was very helpful to my understanding
of the problem.
My problem still is not solved. Your sugestion seems to be true. I guess,
I have a problem with serializer's configuration.
Could you give me some hints, please? What is needed to running correctly
such simple example?
Maybe my "server-config.wsdd" is wrong? I show you my very simple example.
Anyway, When I used to write the similar method
public DataHandler getAttachment();
in normal Java class (NOT EJB) every thing went smoothly. I mean the example
was working.
//----Simple EJB------------------------------------------------------------
package swa;
import javax.activation.*;
import javax.ejb.*;
import org.apache.axis.*;
public class DataProviderBean implements SessionBean {
SessionContext sessionContext;
public void ejbCreate() throws CreateException {
/[EMAIL PROTECTED] Complete this method*/
}
public void ejbRemove() {
/[EMAIL PROTECTED] Complete this method*/
}
public void ejbActivate() {
/[EMAIL PROTECTED] Complete this method*/
}
public void ejbPassivate() {
/[EMAIL PROTECTED] Complete this method*/
}
public void setSessionContext(SessionContext sessionContext) {
this.sessionContext = sessionContext;
}
public DataHandler getAttachment() {
String doc="Hello world.";
//The following two commented lines would force any attachments sent back.
// to be in DIME format.
Message rspmsg =
AxisEngine.getCurrentMessageContext().getResponseMessage();
rspmsg.getAttachmentsImpl().setSendType(org.apache.axis.attachments.
Attachments.SEND_TYPE_DIME);
DataHandler dh = new DataHandler(doc, "text/plain");
return dh;
}
}
//----------------------------------------------------------------------

Call call = (Call) service.createCall();
call.setTargetEndpointAddress( new
URL(http://localhost:7001/webservices/services/DataProvider?wsdl));
call.setOperationName(new QName("DataProvider","getAttachment") );
//This is the target services method to invoke.
QName qnameAttachment = new QName("DataProvider", "DataHandler");
call.registerTypeMapping(Class.forName("javax.activation.DataHandler"),
//Add serializer for attachment.
qnameAttachment,
JAFDataHandlerSerializerFactory.class,

call.setReturnType( qnameAttachment);
call.setProperty(call.ATTACHMENT_ENCAPSULATION_FORMAT,
call.ATTACHMENT_ENCAPSULATION_FORMAT_DIME);
Object ret = call.invoke( new Object[] {
}
); //Add the attachment.
if (null == ret) {
System.out.println("Received null ");
throw new AxisFault("", "Received null", null, null);
}

System.out.println("Received problem response from server: "+ret);

}

//The wrong type of object that what was expected.
System.out.println("Received problem response from server:" +
ret.getClass().getName());
throw new AxisFault("", "Received problem response from server:"
+ ret.getClass().getName(), null, null);
}
DataHandler rdh = (DataHandler) ret;
System.out.println(rdh.getContentType());
System.out.println((String)rdh.getContent());
}
public static void main(String args[]) {
try {
Options opts = new Options(args);
SwAClient echoattachment = new SwAClient();
echoattachment.getAttachment();
}
catch ( Exception e ) {
if ( e instanceof AxisFault ) {
((AxisFault) e).dump();
}
System.err.println(e);
e.printStackTrace();
}
System.exit(18);

Thanks in advance

p.s. When I was working with webservices without attachments I didn't any
problems with my WebLogic's configuration.
