Tomcat 7 manager fails when deploying a WAR file when using the AJP connector

When the Tomcat 7 manager tries to deploy a war file, it fails with the following error:

Feb 28, 2013 8:20:35 AM org.apache.coyote.ajp.AjpMessage processHeader
SEVERE: Invalid message received with signature 8192

ANSWER:
By default, the maximum packet size that can be process by the AJP connector is 8192 bytes.  Do the following to change the default:

1. Edit the Tomcat server.xml file located in the conf directory of your Tomcat installation.
2. Find the Connector entry (show below).

   Code Block
   <Connector port="8009" protocol="AJP/1.3" tomcatAuthentication="false" redirectPort="8443" address="127.0.0.1" maxPostSize="536870912" />

3. Add maxHttpHeaderSize="65536" and packetSize="65536" so that the Connector is as follows:

   Code Block
   <Connector port="8009" protocol="AJP/1.3" tomcatAuthentication="false" redirectPort="8443" address="127.0.0.1" maxPostSize="536870912" maxHttpHeaderSize="65536" packetSize="65536" />

4. When you are satisfied with your changes, save your changes and restart your Tomcat server.

  ANSWER:
• By default, the maximum file size that can be uploaded by the Tomcat 7 manager is 52428800 bytes.  Do the following to change the default:
  1. Edit the web.xml of the Tomcat manager application.  You can find the web.xml file for the Tomcat manager application in the *webapps/manager/WEB-INF directory of your Tomcat installation.
  2. Find the <multipart-config> tag (show below) and increase the max-file-size and max-request-size (both initially set at 52428800) to something larger than the war file size you want to deploy.When you are satisfied with your changes, save your changes and restart your Tomcat server.

     Code Block
     <multipart-config> <max-file-size>52428800</max-file-size> <max-request-size>52428800</max-request-size> <file-size-threshold>0</file-size-threshold> </multipart-config>

  3. When you are satisfied with your changes, save your changes and restart your Tomcat server.
