Tomcat Native library not found

[Phoebe Song]

Dear all,

I started Tomcat and got this error message:

"INFO: The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: C:\Program Files\Java\jdk1.5.0_06\bin;C:\Tomcat\bin"

So what's wrong? I'm using jdk1.5.0_06, tomcat 5.5.1.9

You can safely ignore this message if you want. Basically it is telling you that an optional shared library (dll on Windows) is not found. The APR is the Apache Portable Runtime. This is a native (non-java) library that can improve the performance of Tomcat in certain situations.

On both Windows and Unix/Linux you will need a C compiler to build this library.

In ${tomcat.source}\bin you have 2 folders i64 and x64 (if you have a 64 bit system). Just copy the correct tcnative-1.dll to ${tomcat.source}\bin.
