Umlaute probleme by Axis Call invoke(Object array)

[sindy lee]

Hi,everyone,

i have this problem since 3 days, i'll be crasy!

so at firstz i create the "initoperationDesc()":

        oper = new OperationDesc();
        oper.setName("GetElementsXML");
        param = new ParameterDesc(new QName("http://www.abb.com/printing/SPINEInterfaceWebServices", "IssueDate"), ParameterDesc.IN, new QName("http://www.w3.org/2001/XMLSchema", "dateTime"), Calendar.class, false, false);
        oper.addParameter(param);        
        //oper.setReturnType(new QName("http://www.w3.org/2001/XMLSchema", "string"));
        oper.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);
        oper.setReturnClass(java.lang.String.class);
        oper.setReturnQName(new QName("http://www.abb.com/printing/SPINEInterfaceWebServices", "GetElementsXMLResult"));
        oper.setStyle(org.apache.axis.constants.Style.WRAPPED);
        oper.setUse(org.apache.axis.constants.Use.LITERAL);
        //oper.setUse(org.apache.axis.constants.Use.ENCODED);

        _operations[9] = oper;

than create call:

   protected Call createCall() throws java.rmi.RemoteException {
        try {
            Call _call = super._createCall();
            if (super.maintainSessionSet) {
                _call.setMaintainSession(super.maintainSession);
            }
            if (super.cachedUsername != null) {
                _call.setUsername(super.cachedUsername);
            }
            if (super.cachedPassword != null) {
                _call.setPassword(super.cachedPassword);
            }
            if (super.cachedEndpoint != null) {
                _call.setTargetEndpointAddress(super.cachedEndpoint);
            }
            if (super.cachedTimeout != null) {
                _call.setTimeout(super.cachedTimeout);
            }
            if (super.cachedPortName != null) {
                _call.setPortName(super.cachedPortName);
            }
            Enumeration keys = super.cachedProperties.keys();
            while (keys.hasMoreElements()) {
                java.lang.String key = (java.lang.String) keys.nextElement();
                _call.setProperty(key, super.cachedProperties.get(key));
            }
            // All the type mapping information is registered
            // when the first call is made.
            // The type mapping information is actually registered in
            // the TypeMappingRegistry of the service, which
            // is the reason why registration is only needed for the first call.
            synchronized (this) {
                if (firstCall()) {
                    // must set encoding style before registering serializers
                    _call.setEncodingStyle(null);

                    
                    for (int i = 0; i < cachedSerFactories.size(); ++i) {
                        Class cls = (Class) cachedSerClasses.get(i);
                        QName qName =
                                (QName) cachedSerQNames.get(i);
                        java.lang.Object x = cachedSerFactories.get(i);
                        if (x instanceof Class) {
                            Class sf = (Class)
                                 cachedSerFactories.get(i);
                            Class df = (Class)
                                 cachedDeserFactories.get(i);
                            _call.registerTypeMapping(cls, qName, sf, df, false);
                        }
                        else if (x instanceof javax.xml.rpc.encoding.SerializerFactory) {
                            org.apache.axis.encoding.SerializerFactory sf = (org.apache.axis.encoding.SerializerFactory)
                                 cachedSerFactories.get(i);
                            org.apache.axis.encoding.DeserializerFactory df = (org.apache.axis.encoding.DeserializerFactory)
                                 cachedDeserFactories.get(i);
                            _call.registerTypeMapping(cls, qName, sf, df, false);
                        }
                    }
                }
            }
            return _call;
        }
        catch (java.lang.Throwable _t) {
            throw new org.apache.axis.AxisFault("Failure trying to get the Call object", _t);
        }
    }

So at the end i want to get my string from call.invoke():

 public String getElementsXML(String issueDate) throws RemoteException {
    	if (super.cachedEndpoint == null) {
    		throw new NoEndPointException();
    	}
    	Call _call = createCall();
    	_call.setOperation(_operations[9]);
    	_call.setUseSOAPAction(true);
    	_call.setSOAPActionURI("http://www.abb.com/printing/SPINEInterfaceWebServices/GetElementsXML");
    	_call.setEncodingStyle(null);
    	_call.setProperty(Call.SEND_TYPE_ATTR, Boolean.FALSE);
    	_call.setProperty(AxisEngine.PROP_DOMULTIREFS, Boolean.FALSE);
    	_call.setSOAPVersion(SOAPConstants.SOAP11_CONSTANTS);
    	_call.setOperationName(new QName("http://www.abb.com/printing/SPINEInterfaceWebServices", "GetElementsXML"));
    	_call.setProperty(Call.CHARACTER_SET_ENCODING, "ISO-8859-1");   //this setting just deosn't work
                _call.setProperty(Call.CHARACTER_SET_ENCODING, "UTF-8"); ///this setting just deosn't work neither.
        _call.setSOAPVersion(org.apache.axis.soap.SOAPConstants.SOAP11_CONSTANTS);

        System.out.println("Call encode: " + _call.getProperty(Call.CHARACTER_SET_ENCODING));
        
        
        
    	setRequestHeaders(_call);
    	setAttachments(_call);
    	try {  
    		
    			Object _resp = _call.invoke(new Object[] {issueDate});   
    			
    	                 //here if i print out the string "_resp" to a file. the xml-declaration is just "<?xml version="1.0">" , the 
                            //charset=utf-8 is missing.
                           //and all charachters like ü,ä,ö will be displayed with ?????
    			
    			if (_resp instanceof RemoteException) {
    				throw (RemoteException)_resp;
    			}
    			else {
    				extractAttachments(_call);
    				try {
    					return (String) _resp;
    				} catch (Exception _exception) {
    					return (String) org.apache.axis.utils.JavaUtils.convert(_resp, String.class);
    				}
    			}	

    	} catch (AxisFault axisFaultException) {
    		throw axisFaultException;
    	}
    }

So please help, what did i false?

UTF-8 is the default encoding for XML, so it could be ommitted.

Are you sure the characters are encoded incorrectly or is it possible it is "only" an output problem. Some consoles may not be able to present the characters correctly.

[sindy lee]

Thanks for the Reply,

"printing out" is just the way, what i test the encoded string correct or not, because at the end i want to show this characters in a dialog, and now all data are correct, only these umlaute displayed crasy.

otherwise how can i know, wheater it encoded realy correct or not?

[Hauke Ingmar Schmidt]

You could either in inspect the bytes you receive to see what you get exactly or you save them to a file in a completely controlled way i.e. set the encoding on every conversion from/to String and on every file operation/reader/writer. Then you could just check with an encoding-aware editor.

"Only" the umlauts are crazy is not very helpful. If all other data is latin alphabet without any special characters then most likely a problem will never occur because they have the same code point (ASCII position) in virtually every encoding. The problem still lurks for the time you get some unexpected characters.
