RE: Axis attachment file created in the Temp directory

[Subhendu Kumar mohanty]

Hi 

I am sending part of my wsdl which describes the datahandler

   <complexType name="Image">
    <sequence>
     <element name="dataHandler" nillable="true" type="apachesoap:DataHandler"/>
     <element name="data" type="xsd:base64Binary"/>
     <element name="format" type="xsd:int"/>
    </sequence>
   </complexType>

When I use WSDL2Java tool it creates a java object with three properties. Here is the 
definition of properties 

    private javax.activation.DataHandler dataHandler;
    private byte[] data;
    private int format;

So one of the operation in service returns a message which includes the above message 
(Image object). So when it reaches in client side I get it as a java object.

I have verified with TCPMON that in this case the image comes as attachment.



Thanks,
Subhendu

AFAIK, WSDL has no way to specify attachment handling. The language does
not provide constructions for that. If your client sends or recieves
attachments, you should handle it yourself.
Or am I missing something? May we see your WSDL? Can you send some code
sample?

hi,

I am using the generated client stub classes from the WSDL of the service.
My client program is a java based program. So when I call the method on
client stub , Axis does all the internal processing . The service returns a
datahandler for image and my client program calls the method on stub which
returns a Java object. So in my client I do not do the following thing
mentioned by you.

But when I debug the Axis code I found that when a datahandler comes it
does some processing with ManagedmemoryDataSource.
Is there a way I can tell Axis not to Dump files.

Let me know if this is confusing.

Thanks,
Subhendu

I noted that my Axis client does not dump the attachments to a file unless
I use some data handler function that forces it. For example, if I use
dh.getName() Axis will dump the contents to a temp file and return its
name. If you just use dh.writeTo() to specify where to put the data, Axis
will not created the temp file (if it breates the file, I cannot percieve
it). If you ask for the file, Axis will grant ownership to you, and it is
your responsability to get rid of it (or move it, rename it, whatever).
When I just do
      DataHandler dh = part.getDataHandler();
      dh.writeTo(new java.io.FileOutputStream(myDestinationFileName));
no temp is created.
Cheers.
