Unexpected poller error
Hi ,
I get the following error in catalina.log when i connect the tomcat server over http. However https works fine.
24-Jan-2013 13:06:48.505 SEVERE [http-apr-11831-Poller-0] org.apache.tomcat.util.net.AprEndpoint$Poller.run Unexpected poller error

Problem exists with both tomcat-7.0.35 and tomcat-7.0.33 version. I am using the "TC-Native-1.1.24". I do get the log message of library getting properly loaded as
24-Jan-2013 13:05:58.788 INFO [main] org.apache.catalina.core.AprLifecycleListener.init Loaded APR based Apache Tomcat Native library 1.1.24 using APR version 1.4.6.

Any ideas
Thanks,

Glad to help... I'm sorry that the Java code in the tcnative
distribution was confusing. There is a discussion on the development
list right now about removing that Java code to prevent such confusion.

Hi Christopher,
It worked!! Thanks a ton!!
We were trying to use(compile) the java code in the tcnative distribution and hence the issue.
Everything worked to a T , i.e the http calls that were failing earlier, when we ignored the java code provided with the native distribution.
Thanks once again..you saved me (my team as well ) lot of pain..
Thanks,
Vishal

That's not a valid comparison, unfortunately. For some reason, Java code
remains tucked-away in the tcnative project but it is no longer used (or
shouldn't be). Tomcat includes in its standard distribution everything
you need to use tcnative.
Did you manually compile the Java portion of tcnative? If so, please
remove whatever JAR file you produced from that procedure and re-run
your tests.

No, you should simply ignore all the Java code in the tcnative
distribution.

Hi Chris,
Thanks for prompt reply. I am no java developer so gave me good lead.
I compared the Poll.java in tomcat source ( 7.0.35 src ) with tomcat-native-1.1.24-src
diff apache-tomcat-7.0.35-src/java/org/apache/tomcat/jni/Poll.java tomcat-native-1.1.24-src/jni/java/org/apache/tomcat/jni/Poll.java

Looks like that in latest version of native library , the "addWithTimeout" function is missing.
The "C" counterpart indeed is present in the native library.
Does it make sense to copy the Poll.java from the tomcat src to native library and build the native library??
Thanks,
Vishal

That

native/src/poll.c has it, too:
TCN_IMPLEMENT_CALL(jint, Poll, addWithTimeout)(TCN_STDARGS, jlong pollset,
jlong socket, jint
reqevents,
jlong socket_timeout)
Since you aren't getting a linkage error of some kind, this seems to
be a Java-related problem (and not a native problem). If the method
was missing from the native library, you'd get UnsatisfiedLinkError.
Are you sure you have a clean Tomcat install?
