Why Tomcat raise "Info: The Apache Portable Runtime which allows optimal performance in production environments was not found on the java.library.path: c:\jdk1.5.0_04\bin;C:\WINNT"
Why I can't visit Tomcat? My JDK is 1.5.0_04-b05.

How to configure my Tomcat5.5.12? Please help me!

Thanks in advance!!!

 hi King,

         U better have the environment path variable set first before u start the Tomcat5 server.This can be set by right clicking on MyComputer->properties->Advanced(tab)->Environment Variables-> type JAVA_HOME on the first field and the jdk installation directory on the value field.This may help u i hope.

bye.
