Howdy,
Don't use HttpUtils#parsePostData, don't use HttpUtils at all. Use
request.getParameterMap for the closest equivalent.

Hi All,
Firstly let me explain my setup:
WebServer (apache httpd using jk2 plugin)
Application server tomcat (jakarta-tomcat-4 (See http://cat-4.ora-code.com).1.24)
server.xml entry for AJP:
<Connector className="org.apache.coyote.tomcat4.CoyoteConnector

Source code of org.apache.coyote.tomcat4.CoyoteConnector

"
acceptCount="50" bufferSize="2048" connectionTimeout="10000" debug="0"
enableLookups="false" maxProcessors="75" minProcessors="20"
address="3.130.232.169" port="13763"

proxyPort="0" redirectPort="8443" scheme="ajp13" secure="false"
tcpNoDelay="true" useURIValidationHack="false">
<Factory className="org.apache.catalina.net.DefaultServerSocketFactory"/>
</Connector>
And we are using this application for simple services using HTTP-POST.
Few of the times I get ContentLength in Header > the real size Content in
the Stream. As we are using
"javax.servlet.http.HttpUtils

Source code of javax.servlet.http.HttpUtils

(...)"
to parse out the POST data we get "java.lang.IllegalArgumentException

Source code of java.lang.IllegalArgumentException

: Short
Read"
