| h2. Deploying a WAR to the installed web feature |
| |
| The following steps will describe how to install a simple WAR file (with JSPs or Servlets) to the just installed web feature. |
| # To deploy a WAR (JSP or Servlet) to Jetty, update its MANIFEST.MF to include the required OSGi headers as described here - \\ |
| [http://team.ops4j.org/wiki/display/ops4j/Pax+Web+Extender+-+War+-+OSGi-fy] |
| # Copy the updated WAR (archive or extracted files) to the _deploy_ directory. |
| |
| If you want to deploy a sample web application into Karaf, you could use the following command: |
| {code} |
| karaf@root> osgi:install -s webbundle:http://tomcat.apache.org/tomcat-5.5-doc/appdev/sample/sample.war?Bundle-SymbolicName=tomcat-sample&Webapp-Context=/sample |
| {code} |
| |
| Then open your web browser and point to {{http://localhost:8181/sample/index.html}}. |
