I think you're missing that class in '/WEB-INF/classes/threeparam.class'

no the threeparam.class is there but still error .

this is from catalina log file:

[code] Jul 14, 2009 4:26:44 PM org.apache.catalina.core.AprLifecycleListener init
INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: E:\Program Files\Java\jdk1.6.0_14\bin;.;E:\WINDOWS\Sun\Java\bin;E:\WINDOWS\system32;E:\WINDOWS;E:\WINDOWS\system32;E:\WINDOWS;E:\WINDOWS\System32\Wbem;E:\Program Files\ATI Technologies\ATI.ACE\;E:\Program Files\Java\jdk1.6.0_14\bin;E:\Program Files\QuickTime\QTSystem\;C:\apache-tomcat-6.0.20\lib;"E:\Program Files\Java\jdk1.6.0_14\bin"; [/code]

i think that APR(apache portable runtime) is doing something here .

I don't know the exact cause, but there is some problem with "threeparam" class

No, its Tomcat routine to check PATH environment variable, it would not cause any problem.

ALL classes used in servlets should be in a package with the directory structure under classes reflecting that package structure.

I have resolved the problem :
org.apache.catalina.core.AprLifecycleListener init INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path:

The answer lies in the installation of the dll :tcnative-1.dll. This can be downloaded from the tcnative-1.dll. Simply install in the directory CATALINA_HOME/bin. This results in:
18/08/2009 9:36:52 PM org.apache.catalina.core.AprLifecycleListener init
INFO: Loaded APR based Apache Tomcat Native library 1.1.16.
18/08/2009 9:36:52 PM org.apache.catalina.core.AprLifecycleListener init
INFO: APR capabilities: IPv6 [true], sendfile [true], accept filters [false], ra
ndom [true].

I hope this helps regards. Martin

Do the next thing next. That’s a pretty good rule. Read the tiny ad, that’s a pretty good rule, too.
