Subject AW: HANDLER THREAD PROBLEM when accessing servlet
Date Mon, 07 May 2001 10:22:03 GMT
Hay,

yes it's necessary to compile mod_jk.so, but it's really easy. get the
Tomcat ressources and do exactly what is said in:
http://jakarta.apache.org/tomcat/jakarta-tomcat/src/doc/mod_jk-howto.html#s6
2

The build depends on OS and Apache Version so normally the distributed
binary is matching exactly one environment exapmle. (Probably not yours ;)

If you start the startup.sh (default configuration) TomCat runs standalone
and with the interface for Apache connections. (Port 8080 is standalone
Version, Port 8007 is for mod_jk connections) Therefore you can try both. If
Apache works well with your Tomcat you can remove the:

        <Connector className="org.apache.tomcat.service.PoolTcpConnector">
            <Parameter name="handler" 
 
value="org.apache.tomcat.service.http.HttpConnectionHandler"/>
            <Parameter name="port" 
                value="8080"/>
        </Connector>

Entry form $TOMCATHOME/conf/server.xml to run Tomcat not standalone anymore.

Regards.

Betreff: HANDLER THREAD PROBLEM when accessing servlet


is it really necessary to recompile the mod_jk.so just so that Tomcat will
run fine with Apache?
I have Apache web server and jakarta-tomcat-3.2.1 running on  red hat linux
6.
I am running tomcat using the startup.sh script (I guess this means it's
stand-alone).

I get an error while accessing a servlet in my defined context path but the
example was working well. 
Error is: 
HANDLER THREAD PROBLEM: java.io.IOException: Stream broken
java.io.IOException: Stream broken at
org.apache.tomcat.service.connector.AJP12RequestAdapter.readNextRequest(Ajp1
2ConnectionHandler.java:386) at

org.apache.tomcat.util.ThreadPool$ControlRunnable.run(ThreadPool.java:411)
at java.lang.Thread.run(Thread.java:484) 


Any ideas? TIA.
