tomcat native library?

hello all,

on T2000, i installed tomcat from Coolstack ( CSKtomcatApache Tomcat 5.5.20)

When it start, it print:

"INFO: The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/jdk/instances/jdk1.5.0/jre/lib/sparc/server:/usr/jdk/instances/jdk1.5.0/jr e/lib/sparc:/usr/jdk/instances/jdk1.5.0/jre/../lib/sparc:/usr/lib

"

What's about this library?

When searching on internet, somebody told about "libtcnative.so", but this file doesn't seem to exist in package CSKtomcat .

Anybody can help?

Thanks in advance,

gerard
