<h2>How to access the latest source code?</h2>
<p>
The latest packaged releases are available at http://www.extreme.indiana.edu/soap/
and the latest source (if you want to be on the cutting edge) can now
be obtained now from anonymous CVS at:
<pre>
cvs -d :pserver:anonymous@cvs.extreme.indiana.edu:/l/extreme/cvspub login
CVS password: cvsanon
cvs -d :pserver:anonymous@cvs.extreme.indiana.edu:/l/extreme/cvspub co xsoap-java/PullParser
</pre>
<h2>Why XPP blocks when reading from input stream such as socket?</h2>
<p><strong>NOTE:</strong>pleasue use XPP version 2.1.8 or higher
- in previous version there is ogg-by-one buffering bug.
<p>XPP is a streaming parser however it depends on Reader to provide data in timely manner.
The current JDK implementattion of InputStreamReader will try to read 8KB into internal buffer
<strong>unless</strong> InputStream.available() function returns 0
(this behavior can not be overriden).
<p>Therefore it is necessary to use a wrapper around InputStream to make sure that
InputStreamReader will return as soon as data is available, for example:
<pre>
public class NoBufferingInputStream
extends FilterInputStream {
public NoBufferingInputStream(InputStream in) {
super(in);
}
public int available() { return 0; };
}
</pre>
<p>then one would use following construct to create Reader:
<pre>
InputStream socketInput = ...;
xpp.setInput(new InputStreamReader(
new NoBufferingInputStream(socketInput)));
</pre>
