After upgrading Apache Tomcat and JDK, I saw this exceptions. Work's well on Tomcat 6.0.18_8084, JDK 1.7_017 and Netbeans 7.3. It seems there is some library. Edit code I don't have permissions. Please help.

  • Without seeing the source code or any more information it's impossible to say what the exact cause of this error is. You just have to debug your code. See [What is a Null Pointer Exception, and how do I fix it?](http://stackoverflow.com/questions/218384/what-is-a-null-pointer-exception-and-how-do-i-fix-it) – Jesper Nov 07 '14 at 07:45
  • This is problem not solved by adding library? This is code, where arised exception: public FileInputStream(File file) throws FileNotFoundException { String name = (file != null ? file.getPath() : null); SecurityManager security = System.getSecurityManager(); if (security != null) { security.checkRead(name); } if (name == null) { throw new NullPointerException(); } if (file.isInvalid()) { throw new FileNotFoundException("Invalid file path"); – Serg Bash Nov 07 '14 at 08:21
