title: message java.lang.IllegalStateException: No output folder
body: <p>I am new to Tomcat on Windows. I am trying to deploy my Java project which I have made in RHEL 5 using Tomcat. Now I want to run that project on window. So I copied and pasted my project folder inside the Tomcat web apps Directory</p>
  
  <pre><code>i.e C:\Program Files\apache-tomcat-6.0.37\webapps
  </code></pre>
  
  <p>but I am unable to run the project as I am facing below error while opening my first login page. Do I need to make any further changes in code or web.xml file as I am now deploying it on Windows?</p>
