I have a properties my web application needs, but it is not available at package time. So I put it in TOMCAT_HOME/lib and the application finds it with no problem. When I run Tomcat with security manager enabled, the file is never found. I have granted permission to read it, but it is still not found. I am not getting any security error messages, only that the file is missing.

When Tomcat is run with security manager enabled, is the classpath different? Is it more restricted?

    How are you trying to load this properties file? A code sample would help. – Christopher Schultz Jul 24 '13 at 22:11
  • I am using the apache-configuration file "PropertiesConfiguration.java". It takes a single parameter which is the name of the properties file to read from. It finds this file on the classpath. PropertiesConfiguration config = new PropertiesConfiguration("myfile.properties"); – user1315531 Jul 25 '13 at 19:44

I found the problem. My code was using:

Thread.currentThread().getContextClassLoader().getResourceAsStream(inputFile);

I needed to grant RuntimePermission to get the class loader.

permission java.lang.RuntimePermission "getClassloader";
