Accessing Large Files from a WebService

Question

Hi!
I have developed a Repository Manager in Java for SAP NW04.
I have also created a WebServices CLIENT in the WebService Perspective by providing a WSDL file.
Then I built an EAR file and deployed it with SDM.
The Repository Manager then uses the web service client to access FILES exposed by the WebService.
It works but ...
When I tried to access a files of 14 MB:s and larger from the web service, the J2EE Engine goes down,
and restarts.
What should I do?
There is a setting in Visual Admin called "HTTP Tunneling" with the following setting:
MaxInputbufferSize = 10 485 760
Should I alter this setting, or is there a way to chunk up these files in some way?
Any ideas?
Is this the proper forum for my question?

see sample below:
package sample;
import java.util.jar.*;
import java.util.*;
import java.util.zip.*;
import java.io.*;
public class TestJar {
     public static void main(String args[]) throws Exception {
          JarFile jarFile = new JarFile(args[0]);
          for (Enumeration e=jarFile.entries(); e.hasMoreElements(); ) {
               ZipEntry entry = (ZipEntry)e.nextElement();
               if (entry.getName().equals("Test.java")) {
                    BufferedInputStream buf = new BufferedInputStream(jarFile.getInputStream(entry));
                    BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream("gone.java"));
                    int ch = 0;
                    while ((ch = buf.read()) != -1) {
                         out.write(ch);
                    out.flush();
                    out.close();
                    buf.close();
}
