Problems deploying WAR file from Netbeans to Tomcat

I'm trying to configure build.xml files for build forge, but it seems like I am having trouble with the libraries required for the java servlet pages. I am actually trying to use OWASP's AntiSamy library but I keep getting a Policy Exception followed by a file not found

org.owasp.validator.html.PolicyException: java.io.FileNotFoundException: C开发者_Go百科:\Program%20Files \Apache%20Software%20Foundation\apache-tomcat-6.0.29\webapps\XSSDemo\WEB-INF\classes\...\antisamy.xml (The system cannot find the path specified)

The antisamy.xml file is definitely in this location, however.

So I tried using Netbeans to clean and build a WAR file that I would have expected to work, since the web app works fine when I run it through Netbeans. However, I get the same problem. Is there possible some reference that Netbeans is creating when I run the app through the ide that is not occurring in the WAR deployment? Could the URL Encoding in the antisamy.xml location be causing problems?

Thanks for the help.

Edit: I compressed the long class path into the three dots here. The actual response has the actual class path. I am not getting any kind of security errors.

The problem I had was not actually with the deployment--it was the file reference itself in my java servlet. The encoding in the path '%20' in the Program Files folder caused a FileNotFoundException. The reason this did not occur in netbeans is because the deployed files are in a c:\users... folder and there are no spaces to be encoded. The also explained why the application ran well on other computers with their tomcat folders directly on the root directory. This is the actual solution to my problem. Thanks for all your help.
