problem invoking axis service from PDA with CDC configuration

[Michele Amoretti]

Hi all,

I have a client running on a PDA with JVM 1.3, and CDC configuration. The
client should invoke a Web Service deployed in Tomcat on a server.

The problem is that when the client invokes the service, it always receive a
null response, and (strange thing) the server does not seem to receive any
request (it should log something on stdout but it doesn't). No exception is
raised!

If I run the client code on my laptop, the invocation is correct and the
server logs correctly.

Any idea? Maybe some .jar is lacking on the PDA?

Re: using MTOM in a AXIOM-based WS

[Michele Amoretti]

Yes I read the guide but I need a more complete example.


In my MTOM implementation I did not used a base64 encoded string.. I simply
did:

public OMElement getPriceFile(OMElement element) throws XMLStreamException {
   element.build();
   element.detach();

   OMElement fileNameElement = element.getFirstElement();
   String fileName = "C:\\Programmi\\" + fileNameElement.getText();

   System.out.println("fileName = " + fileName);

   OMFactory fac = OMAbstractFactory.getOMFactory();
   OMNamespace omNs =
   fac.createOMNamespace("http://quickstart.samples/xsd";, "ns");
   OMElement fileElement = fac.createOMElement("file", omNs);

   FileDataSource dataSource =
   new FileDataSource(fileName);

   DataHandler dataHandler = new DataHandler(dataSource);

   // create an OMText node with the above DataHandler and set
optimized to true
   OMText textData = fac.createOMText(dataHandler, true);

   fileElement.addChild(textData);

   OMElement response = fac.createOMElement("getPriceFileResponse",
omNs);
   OMElement priceFile = fac.createOMElement("priceFile", omNs);
   priceFile.addChild(textData);
   response.addChild(priceFile);

   return response;
   }

And it does work wheter I transfer a txt, a pdf, a jpg..

The WSDL currently defines:

   
   
   
   
   
   
   

Is this bad?

Thanks

Re: using MTOM in a AXIOM-based WS

[Michele Amoretti]

Argh I am sorry, I made a mistake and I was transferring another file (of
24KB size) and saving it with the wrong name (and extension).

Now I can say that mymtomwithaxiomexample works properly and could
be inserted in the samples folder of axis2 distribution!

I only have one doubt about the WSDL:

For the
operation which has a parameter which is a binary file, which type
should I declare for the parameter? string?

In my enhanced StockQuoteservice.wsdl (which has a getPriceFile method
which receives a file name as input and returns a priceFile as
outpput), I wrote:


  http://www.w3.org/2001/XMLSchema";
attributeFormDefault="qualified" elementFormDefault="qualified"
targetNamespace="http://quickstart.samples/xsd";>
  
  
  
  
  
  
  
  
  
  
  
  
  
  


Is this correct?

Thanks
Michele

No, I tried this but the problem persists: only 24KB of the file are
transferred from the service to the client. :(

I don't know if there is a way to say the same thing from the server, or
if it is even necessary. The reason had something to do with whether the
length was being passed. Sorry I am vague but this didn't happen directly to
me so I don't know the exact particulars.

Should I make some adjustments in axis2.xml, or in Tomcat configuration?

Subject: using MTOM in a AXIOM-based WS

Hello,

I am trying to create a new version of the "quickstartaxiom" sample, with the 
StockQuoteService providing a getPriceFile operation which returns a file using MTOM.

In the MTOM tutorial unfortunately there are only parts of code (I cannot find 
a complete example in axis2-1.1.1 - the mtom sample is not based on AXIOM) thus 
I had to write the other parts, but since I have some problems in invoking the 
service I think I have made a mistake somewhere.


My new ***AXIOMClient*** should set

options.set(Constants.Configuration.ENABLE_MTOM, Constants.VALUE_TRUE);

as explained in the tutorial, but the Options class has no "set"
method and I cannot find the right one..

Btw, I added to the client the following method:

   public static OMElement getPriceFilePayload(String priceFileName) {
OMFactory fac = OMAbstractFactory.getOMFactory();
OMNamespace omNs = fac.createOMNamespace(

"http://quickstart.samples/xsd";, "tns");

OMElement method = fac.createOMElement("getPriceFile", omNs);
OMElement value = fac.createOMElement("priceFileName", omNs);
value.addChild(fac.createOMText(value, priceFileName));
method.addChild(value);
return method;
}

and in the main() method of the client I added the following part, for 
getFilePrice invocation:

OMElement getPriceFilePayload = getPriceFilePayload("prova.txt"); 
...
result = sender.sendReceive(getPriceFilePayload);
OMElement ele = result.getFirstElement();
OMText binaryNode = (OMText) ele.getFirstOMChild();
DataHandler actualDH = (DataHandler) binaryNode.getDataHandler();
File file = new File("prova.txt");
FileOutputStream fileOutputStream = new FileOutputStream(file);
actualDH.writeTo(fileOutputStream);
fileOutputStream.flush();
fileOutputStream.close();



In the ***StockQuoteService*** the getPriceFile method is implemented as 
follows:


 public OMElement getPriceFile(OMElement element) throws XMLStreamException {
element.build();
element.detach();

OMElement fileNameElement = element.getFirstElement();
String fileName = fileNameElement.getText();

System.out.println("fileName = " + fileName);

OMFactory fac = OMAbstractFactory.getOMFactory();
OMNamespace omNs =
fac.createOMNamespace("http://quickstart.samples/xsd";, "ns");
OMElement fileElement = fac.createOMElement("file", omNs);

FileDataSource dataSource =
new FileDataSource(fileName);

DataHandler dataHandler = new DataHandler(dataSource);

// create an OMText node with the above DataHandler and set optimized 
to true
OMText textData = fac.createOMText(dataHandler, true);

fileElement.addChild(textData);

OMElement method = fac.createOMElement("getPriceFileResponse", omNs);
OMElement value = fac.createOMElement("priceFile", omNs);
value.addChild(textData);
method.addChild(value);

return method;
}


Is this ok? Where should I store the "prova.txt" file in the server?
In the same folder in which I put the *.aar file?

I attach to this mail the wsdl of the service, and the configuration file.


I am using Tomcat as servlet engine, and the logs are clean at the server side.

At the client side the error message is:

[java] org.apache.axiom.om.OMException: Referenced Attachment not found in 
the MIME Message.

You can find a rather complicated deprecated MTOM Sample based on
Axiom in here[1].


Ok I will study this.


> options.set(Constants.Configuration.ENABLE_MTOM, Constants.VALUE_TRUE);
As Valerie mentioned this should be setProperty...


Ok



But AFAIKS you are trying to return an attachment from a server.. For
that you need to enable MTOM in the server side by adding the
following parameter to your axis2.xml or to the service.xml..
true



Yes I did it!


> Is this ok? Where should I store the "prova.txt" file in the server?
You can try giving an absolute path...


Ok



Please use the TCPMON[2] to capture your messages and check whether
the attachment is attached as a MIME part.

Thanks,
Thilina



I have question about the WSDL for the MTOM-based service... For the
operation which has a parameter which is a binary file, which type
should I declare for the parameter? string?

In my enhanced StockQuoteservice.wsdl (which has a getPriceFile method
which receives a file name as input and returns a priceFile as
outpput), I wrote:


http://www.w3.org/2001/XMLSchema";
attributeFormDefault="qualified" elementFormDefault="qualified"
targetNamespace="http://quickstart.samples/xsd";>
















Is this correct?

Thank you very much
