Hi
I wrote a session bean that was deployed as web service and was sending the
content of file on invocation
of a method. To do that you don't have to use a DataHandler object. To my
understanding DataHandler
is just a wrapper object which can contain another object and some more
information for that object.
I am adding the code of my session bean I wrote to transmit the file. It is
quite simple and maybe it will
solve your problem:-
public byte[] echo(String fileName)
{
System.err.println("In echo");
byte[] retValue = new byte[0];
if(fileName==null)
{
System.err.println("FileName is null");
}
else
{
System.err.println("Recieved \""+fileName+"\".");
File file = new File(fileName);
int length = (int)(file.length());
FileInputStream fileiStream = null;
if(file.exists())
{
try
{
fileiStream = new FileInputStream(file);
retValue = new byte[length];
fileiStream.read(retValue);
}
catch(IOException ex)
{ ex.printStackTrace(); }
finally
{
try
{
fileiStream.close();
}
catch(IOException ex)
{ ex.printStackTrace();}
}
}
}
return retValue;
}
I have a public method called echo that just reads the file and transmits as
a byte[] to the client. With this as byte[]
is a XML data type you should be able to write a C# client with the WSDL of
above method.
