SECTION: 650-JBoss TITLE: JBoss Deployment Errors QUESTION: I am getting errors when I deploy the Jetty sar in JBoss. What can I do? First, check that you have removed any old Jetty or Tomcat sars from the JBoss deployment directory. <p> Second, read this JBoss forum entry regarding incorrect web.xml files in the JBoss distro: <a href="http://www.jboss.org/index.html?module=bb&op=viewtopic&t=63494">http://www.jboss.org/index.html?module=bb&op=viewtopic&t=63494</a> <p> Third, try the most recent JettyJBoss sar. <p> Fourth, try recompiling the JettyJBoss sar against your version of JBoss: <ol> <li> Download a jetty-x.x.x-all.zip and unzip it. <li> Edit the <code>$JETTY_HOME/extra/j2ee/jboss.properties</code> file and change the JBoss version and location to match your installation. <li> Do an <code>ant all</code> build in the <code>$JETTY_HOME/extra/j2ee</code> directory. <li> Copy the sar produced from the build to your JBoss deploy directory (ensuring you have removed any old sars first). </ol>
