Subject Re: Apache Tomcat unable to send the request. tomcat throwing 502 Gate Way error
Date Tue, 16 Aug 2011 07:08:50 GMT
Hi Andre

Sorry for this, I had pasted the entire xml file.. I am hereby providing the
server.xml with removing the commented parts.

<?xml version='1.0' encoding='utf-8'?>


<Server port="8005" shutdown="SHUTDOWN">


  <Listener className="org.apache.catalina.core.AprLifecycleListener"
SSLEngine="on" />

  <Listener className="org.apache.catalina.core.JasperListener" />

  <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener"
/>
  <Listener
className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />

  <GlobalNamingResources>

    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />
  </GlobalNamingResources>


  <Service name="Catalina">



    <Executor name="tomcatThreadPool" namePrefix="catalina-exec-"
        maxThreads="150" minSpareThreads="4"/>

    <Connector executor="tomcatThreadPool"
               port="8082" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />


    <Engine name="Catalina" defaultHost="localhost" jvmRoute="msf1">


      <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
             resourceName="UserDatabase" digest="sha"/>


      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">



      </Host>
    </Engine>
  </Service>
</Server>
