he body of the request is lost when you send POST

[johnbat26]

Hello!
I have a critical issue, most likely associated with JBossWeb-2.0.1.GA (Tomcat 5.5.X).
------------------------------
My environment:
OS: RHEL 5 x86 or x86-64;
JVM: sun-jdk-1.6.0.16 or jrockit-R27.5.0-jdk1.6.0_03;
AS: JBoss AS 4.2.2.GA (with Tomcat 5.5.X (JBossWeb-2.0.1.GA ) inside)

------------------------------
I implemented web-service using apache xml-rpc 3.1.2.
Then I call it from the http client. (apache httpclient 4.0).
This my request:
Code:

POST /cas-services-verimatrix-pull/pull HTTP/1.1
Host: 10.20.2.150:8080
Accept: */*
Content-Type: text/xml
Content-Length: 391

<?xml version="1.0" encoding="UTF-8"?>
<methodCall>
<methodName>EISTMPull.getEntitlement</methodName>
<params>
<param><value><string>00020215B9FE</string></value></param>
<param><value><base64>

</base64></value></param>
<param><value><array><data>
<value><string>DTV</string></value>
<value><string>PPV</string></value>
</data></array></value></param>
</params>
</methodCall>

This request is almost always handled properly.But sometimes the body of the HTTP request is lost and the server sends a reply, as if the request body is empty:
Code:

HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
X-Powered-By: Servlet 2.4; JBoss-4.2.2.GA (build: SVNTag=JBoss_4_2_2_GA

Content-Type: text/xml
Content-Length: 312
Date: Fri, 07 Aug 2009 15:16:19 GMT

<?xml version="1.0"?>
<methodResponse>
<fault>
<value>
<struct>
<member>
<name>faultString</name>
<value>java.lang.NoSuchMethodException: ru.cti.oss.cas.verimatrix.pull.Pull.getEntitlement()</value>
</member>
<member>
<name>faultCode</name>
<value><int>0</int></value>
</member></struct></value>
</fault>
</methodResponse>

First used xml-rpc version 2, then I updated it to 3.1.2. Accordingly, the
error must be at the level of tomcat.

I fulfilled a lot of tests. This error does not depend on the load application
server. Fortuitous . But because of this, our clients can not work normally.
Therefore, I think this problem critical.

Please, help with what could be wrong?

Post the client code which sends this request.

[jfclere]

"AS: JBoss AS 4.2.2.GA (with Tomcat 5.5.X (JBossWeb-2.0.1.GA ) inside)"

No JBossWeb-2.0.1.GA is based on Tomcat 6.0.x.

jaikiran See https://issues.apache.org/bugzilla/attachment.cgi?id=24267 I think that the client code is there.

How can I check the versione tomcat into my Jboss

No JBossWeb-2.0.1.GA is based on Tomcat 6.0.x.

Yeah, that's one of the things that we told JohnBat over #jboss IRC where he asked pinged for inputs. But the X-Powered-By header output seems to be adding to the confusion :) :

How I may upgrade jBossWEb up to 2.1.4 in Jboss 4.2.2 ?

[johnbat26]

I embed several count of code in Http11Processor and StandardEngineValve.
In Http11Processor,process() I added next after invoke
inputBuffer.parseRequestLine(); :

if (request.unparsedURI().equals("/lost-post/generic"))
 {
log.error("----------------------------------------------------------");
 StringBuffer stringBuffer = new StringBuffer();
 for (int i = 0; i < inputBuffer.buf.length; i++) {
 stringBuffer.append((char) inputBuffer.buf);
 }

 log.error(stringBuffer);
 log.error("LENGTH: "+ inputBuffer.buf.length);

 log.error("++++++++++++++++++++++++++++++++++++++++++++++");
 }

and in StandardEngineValve.invoke() I added next code:

if (request.getWrapper().getName().equals("LostPostGenericServlet"))
 {

log.error("-----------------------------------------------------------------------------");
 StringBuffer stringBuffer = new StringBuffer();
 InputStream input = request.getInputStream();
 int i=request.getContentLength();
 int c;
 while (((c = input. read()) != -1) && (--i > 0)) {
 stringBuffer.append((char) c);
 }
 input.close();

 log.error(stringBuffer);
 PrintWriter out = response.getWriter();
 if (stringBuffer.length() > 0) {
 StringBuffer xmlBuffer = new StringBuffer();
 xmlBuffer.append("<?xml version='1.0' encoding='UTF-8'?>");
 xmlBuffer.append("<methodCall>");
 xmlBuffer.append("OK");
 xmlBuffer.append("</methodCall>");
 out.print(xmlBuffer);
 System.out.println("OK");
 } else {
 StringBuffer xmlBuffer2 = new StringBuffer();
 xmlBuffer2.append("<?xml version='1.0' encoding='UTF-8'?>");
 xmlBuffer2.append("<methodCall>");
 xmlBuffer2.append("FAILED");
 xmlBuffer2.append("</methodCall>");
 out.print(xmlBuffer2);
 System.out.println("FAILED");
 }
 out.close();
 log.error("++++++++++++++++++++++++++++++++++++++++++++++");
 return;
 }

-----------------------
So added code in Http11Processor print entire buffer, whereas code in
StandardEngineValve print content of body from CoyoteInputStream.
When I increase loading at tomcat (with help of Grinder) happen this error,
and code in Http11Processor print normal request with body, whereas code in
StandardEngineValve print empty string:

Therefore error happen inside tomcat ! During parsing body
of request. Often this happen during increase loading at other applications
deployed in tomcat.

I conclude several tomcat classes, which uses in JBossWeb, because don't know,
which version of tomcat used in JBossWeb 2.0.3.GA

Many thanks in advance for any some help.

I changed connector to Http11NioConnector:

<Connector port="8080" address="${jboss.bind.address}"
 protocol="org.apache.coyote.http11.Http11NioProtocol"
 redirectPort="8443"/>

this problem persist :(
