Here's a fix for JServInputStream. I've given it limited testing and it
appears to correct the problem.
The idea is pass the content-length in on the constructor or
JServInputStream and then track the data as it is consumed. When it's all
gone, start returning 0's. The unknown content-length of -1 also needs to be
supported since most requests are in that mode.
// Set up the servlet's I/O streams
servlet_in = new JServInputStream(getContentLength(), in);
/**
* ServletInputStream implementation as inner class
*/
protected class JServInputStream extends ServletInputStream {
protected InputStream in;
protected int length;
public JServInputStream(int length, InputStream in) {
this.length = length;
this.in = in;
}
public int read() throws IOException
if ((length-- > 0) || (length == -1))
return in.read();
return -1;
}
public int read(byte b[]) throws IOException {
if (length == -1)
return in.read(b, 0, b.length);
int len = b.length;
if (len > length)
len = length;
length -= len;
if (len > 0)
return in.read(b, 0, len);
return 0;
}
public int read(byte b[], int off, int len) throws IOException {
if (length == -1)
return in.read(b, off, len);
if (len > length)
len = length;
length -= len;
if (len > 0)
return in.read(b,off,len);
return 0;
}
public long skip(long n) throws IOException {
if (length == -1)
return in.skip(n);
if (n > length)
n = length;
length -= n;
if (n > 0)
return in.skip(n);
return 0;
}
public void close() throws IOException {
// Ignore closing of the input stream since it also
// close the output stream.
// conn.in.close();
}
/**
We must implement this method because java.io.InputStream
javadocs says that this will return 0. Since we use a long
internally, it must be cast to an int. ugly. -JSS
*/
public int available() throws IOException {
if (length == -1)
return in.available();
return length;
}
}
