title: Why JNLP (Java Web Start) does not download jar file?
body: <p>Why Java Web Start does not download Jar files which specified in resources? </p>
  
  <p>I'm using jdk 1.5 to build my application. There is good reasons to use jdk 1.5 so that I can not upgrade it.</p>
  
  <p>Jdk demo and samples used a servlet to specify location of JNLP and security checking. If I use this servlet, jnlp does not work and its jar files does not download while if write address of jnlp directly in codebase attribute by prefixing file:/localhost/ it works! </p>
