I basically followed the same set of instructions for Tomcat 5.5.28 on Fedora
11 for compilation. I use the stock Sun JRE / JDK (1.6.0_18 32 bit), and the
stock Apache Tomcat 5.5.28 downloaded from tomcat.apache.org.
Compilation went normally, and I put the libraries (with symbolic links) into
~/Apache/apache-tomcat-5.5.28/bin. I then tried the following four methods to
load the native libraries.
1. -Djava.library.path set in CATALINA_OPTS in catalina.sh
CATALINA_OPTS="-Djava.library.path=/home/mdeggers/Apache/apache-tomcat-5.5.28/bin"
2. -Djava.library.path set in JAVA_OPTS in catalina.sh
JAVA_OPTS="-Djava.library.path=/home/mdeggers/Apache/apache-tomcat-5.5.28/bin"
3. export LD_LIBRARY_PATH=/home/mdeggers/Apache/apache-tomcat-5.5.28/bin
4. Placing the library in /usr/local/Sun/jre1.6.0_18/lib/i386/ (reported to be
on the java.library.path)
In all four cases, the tcnative library failed to load. In the first two cases,
the INFO message indicated that the library was not found in
/home/mdeggers/Apache/apache-tomcat-5.5.28/bin. In the last two cases, the INFO
message listed all directories in java.library.path
The same steps were used to build and deploy the tcnative libraries on Tomcat
6.0.24. Configurations 1 and 3 from above were tried.
Both worked for Tomcat 6.0.24 as indicated by the INFO message:
INFO: Loaded APR based Apache Tomcat Native library 1.1.19.
Jan 21, 2010 5:48:15 PM org.apache.catalina.core..AprLifecycleListener init
INFO: APR capabilities: IPv6 [true], sendfile [true], accept filters [false],
random [true].
There seems to be an issue with Tomcat 5.5.28 and the tcnative libraries.
I had a similar experience with Tomcat 5.5.28 under Windows/XP Professional
(same version of JRE/JDK - obviously for Windows) and the binary download of
the native libraries.
Tomcat 5.5.28 failed to load the libraries when an environment variable was set
in catalina.bat.
Tomcat 6.0.24 worked with the native libraries (at least they loaded), but on
shutdown I received the following SEVERE error.
Jan 21, 2010 2:16:09 PM org.apache.tomcat.util.net.AprEndpoint$Acceptor run
SEVERE: Socket accept failed
org.apache.tomcat.jni.Error: A blocking operation was interrupted by a call to
WSACancelBlockingCall.
at org.apache.tomcat.jni.Socket.accept(Native Method)
at
org..apache.tomcat.util.net.AprEndpoint$Acceptor.run(AprEndpoint.java:
1156)
at java.lang.Thread.run(Thread.java:619)
I guess it's time to set up debug logging on Tomcat and see if I can figure out
what's going on.
Any thoughts before I wade into megabytes of logs would be appreciated.
