Cannot find the JRE for some reason

I have the following error - and I am getting a 404 problem. I think they are related. Is this a class path error?

Apache Tomcat Native library which allows optim开发者_开发问答al performance in production environments was not found on the java.library.path: C:\Program Files\Java\jre6\bin;....

They're not related, the message is just a warning...

It's not saying JRE was not found. It just mentions where did it look for Apache Native, which is an optional speed-up you don't need I guess.

This warning is about the Tomcat native libraries which are optional. As the warning states, the native libraries can boost performance. This warning is probably unrelated to your HTTP 404 error. Please provide more detail about your 404 error. What is the url? What <servlet-mapping>s and <filter-mapping>s do you have defined in web.xml?
