WebService (4)-axis Advanced features transfer files

Files are mainly used in a DataHandler class, which is a dedicated transmitter that can serialize files. And then we get an input stream from the transporter, and the data from the input stream is the file we sent from the client.

Eg: transfer a file from the client to the server
(1) WebService server-side method,
Public String Transfer (DataHandler handler,string fileName) {
File File = new file (fileName);
int flag = 0;
if (Handler==null | |) fileName = NULL | | "". Equals (FileName)) {
return "Failure";
}
InputStream input = null;
FileOutputStream fos = null;
try {
input = Handler.getinputstream ();
FOS = new FileOutputStream (file);
byte[] buffer = new byte[1024];
while (input.read (buffer)!=-1) {
Fos.write (buffer);
}
catch (Exception ex) {
Ex.printstacktrace ();
} finally{
if (input!=null) {
try {
Input.close ();
catch (IOException e) {
TODO auto-generated Catch block
E.printstacktrace ();
}
}
if (Fos!=null) {
try {
Fos.close ();
catch (IOException e) {
TODO auto-generated Catch block
E.printstacktrace ();
}
}
}
Return "File Trasfer Success" +file.getabsolutepath ();
}

Note: You can specify metadata about special operations on the service by using the <operation> tag. This maps the Java parameter names of the methods to the specific XML names.
Specifies a specific pattern for the parameter and maps a specific XML name to a specific action. For example
<operation name= "Method" >
</operation>
