title: "PWC6345: There is an error in invoking javac." error when using Jetty WTP plugin to deploy a JSP page on Jetty
body: <p>I'm trying to deploy a JSP-page on Jetty, using the <a href="http://wiki.eclipse.org/Jetty_WTP_Plugin" rel="noreferrer">Jetty WTP plugin</a> for Eclipse. But I get the error below. It looks like Jetty can't find <code>javac</code>. Is there any settings I have to do for the Jetty WTP plugin in Eclipse or how do I fix this?</p>
  
  <p>The JSP page works fine if I export my project as a <code>.war</code>-file to <code>jetty\webapps</code> and then start Jetty manually using <code>java -jar start.jar</code>. But it doesn't work if I deploy using the Jetty WTP plugin for Eclipse as described.</p>
  
  <p>I have my <code>JAVA_HOME</code> set to <code>C:\Program Files (x86)\Java\jdk1.7.0_01</code> and I use Jetty 8.0.4 on Windows 7.</p>
  
  <p>Servlets is working fine with the current setup. Any suggestions on how to solve this for JSP pages?</p>
