Re: [xfire-user] How to download large file from service side to client?
Hi,
Try add this function to MTOM exmaple that is shipped with XFire
public DataHandler echoData(DataHandler handler)
{
try
{
System.out.println(handler.getContent().toString());
}
catch (IOException e)
{
e.printStackTrace();
}
return handler;
}
Add it to interface too.
Client side code :
File file = new File(c:\\temp\\pic1.png);
DataSource fileSource = new FileDataSource(file);
DataHandler dataHandlerResult2 = service.echoData(new
DataHandler(fileSource));
fileSource = dataHandlerResult2.getDataSource();
try
{
InputStream in = fileSource.getInputStream();
File outputFile = new File(c:\\temp\\outputpic1.png);
OutputStream out = new BufferedOutputStream(new
FileOutputStream(outputFile));
byte[] buffer = new byte[2048];
int len;
while ((len = in.read(buffer)) 0) {
out.write(buffer, 0, len);
}
in.close();
out.flush();
out.close();
System.out.println(file saved.);
}
catch ( IOException e1 )
{
// TODO Auto-generated catch block
e1.printStackTrace();
}
You should run original MTOM example first to be sure you have all
libraries in place.
I am not able to run XFire MTOM under Oracle OC4J 10.1.2 and 10.1.3,
but Weblogic 8.1 SP6 works fine.

Hi,
Can someone post an example how to obtain file from serivce?
I mean something like this:
.
Client client = Client.getInstance(service);
...
DataHandler dh = service.getFile(file_name_on_server);
For a while I have been trying to solve the problem and had no luck so far.
Funny thing is that I can replicate XFire MTOM examples where client sends
an instance of DataHandler or DataSource to service and receives content as
a String. I assume, if these examples run in my environment than I have
properly configured my service and client. So, why
service.getStringFrom(new DataHandler(new
FileDataSource(file_name_on_clien))) works, and
DataHandler dh = service.getFile(file_name_on_server) doesn't?
You may look at the detailed description of the problem here:
http://www.nabble.com/MTOM.-Can-my-webservice-return-DataHandler--tf3607587.html
Or, may be you can explain the reason for NullPointerException I am getting?

You can also try to use slightly different approach, your server
method can return only a url to file exposed by http server and then
you can download file with regular ( no webservice ) code.

Hi, it looks correct. Does the file exists? org.codehaus.xfire.attachments.AttachmentUtil.getAttachment(AttachmentUtil.java:33) It couses NullPointerException here. Try create File object from path then check if file exists and create FileDataSource and DataHandler. Regards, Zdenek On 4/24/07, seego [EMAIL PROTECTED] wrote: Zdeněk, I have tried this. No luck.

Re: [xfire-user] How to download large file from service side to client?
Hi Tomek, Hi Seego, I have tested it. It works fine. java 1.5 build 11 Tomcat 5.5 last stable XFire 1.2.5 (I copied content of xfire lib directory into Tomcat55\shared\lib\ and restarted Tomcat) Maven 2.0.6 EasyEclipse 1.2.1 I downloaded your zip file, then I created file in temp directory with some data. mvn eclipse:eclipse ( I run client from eclipse) mvn install war:war than I copied created war file into Tomcat webapp directory wsdl document http://localhost:8080/xfire-mtom/services/MTOMService?wsdl I run client application from eclipse. Everything was ok. Í have got content with this code: System.out.print(result + dh2.getContent().toString()); Which Tomcat version do you use? Which java do you use? I have tested my code with java 1.4.2 build 6 and java 5 several builds. There must be problem in your your enviroment, libs ...

It seems that service responds correcly, but the client gets confused for some reason I am 100% shure that it is not a problem of missing classes or file. I just need someone to confirm that it doesn't work, so I can move forward with my project. Thanks. Zdeněk Vráblík-3 wrote: Hi, it looks correct.
