PostMethod with large XML passed in setRequestEntity is truncated

Question

Hi,
I use PostMethod to transfer large XML to a servlet.
CharArrayWriter chWriter = new CharArrayWriter();
post.marshal(chWriter);
//The chWriter length is 120KB
HttpClient httpClient = new HttpClient();
PostMethod postMethod = new PostMethod(urlStr);
postMethod.setRequestEntity(new StringRequestEntity(chWriter.toString(), null, null));
postMethod.setRequestHeader("Content-type", "text/xml");
int responseCode = httpClient.executeMethod(postMethod);
String responseBody = postMethod.getResponseBodyAsString();
postMethod.releaseConnection();
When I open the request in doPost method in sevlet:
Reader inpReader = request.getReader();
char[] chars = MiscUtils.ReaderToChars(inpReader);
inpReader = new CharArrayReader(chars);
//The data is truncated (in chars[]) ???
static public char[] ReaderToChars(Reader r) throws IOException, InterruptedException {
//IlientConf.logger.debug("Start reading from stream");
BufferedReader br = new BufferedReader(r);
StringBuffer fileData = new StringBuffer("");
char[] buf = new char[1024];
int numRead=0;
while((numRead=br.read(buf)) != -1){
String readData = String.valueOf(buf, 0, numRead);
fileData.append(readData);
buf = new char[1024];
return fileData.toString().toCharArray();
Any idies what can be the problem??

Hi,
I use the same code and have 2 tomcats running with the same servlet on each of them.
One running on Apache/2.0.52 (CentOS) Server and the second running on Apache/2.0.52 (windows XP) Server.
I managed to post large XML from (CentOS) Server to (windows XP) Server successfully and failed to post large XML
from (windows XP) Server to (CentOS) Server.
I saw somthing called mod_isapi that might be disabling posting large XML files.
Can anyone help me on going over that limitation?
Thanks,
Lior.
