I forgot to include the Groovy script itself that does all the heavy-lifting in my previous mail - see Groovy.SshHelperClass below. Also, there's a much better way of calling this groovy "sshHelper" class out of a single groovy invocation in a 2.0 document. Groovy directly outputs wikitext, the renderer takes care of the rest.
==== Use Groovy Script run server processes and display result ==== See [[SshHelperClass?viewer=code]], [[ http://blog.asyd.net/2008/12/xwiki-cest-decidemment-magique/]] {{groovy}} println "==== Call parseGroovyFromPage('Groovy.SshHelperClass') ====" def sshHelper = xwiki.parseGroovyFromPage("Groovy.SshHelperClass") sshHelper.openSession("127.0.0.1", "22", "tomcat-ssh-slave", "/usr/share/tomcat6/.ssh/id_dsa", "") println "==== Output from 'uname -a' ====" println "##" + sshHelper.runCommand("uname -a") + "##" println "==== Output from 'free' ====" println "##" + sshHelper.runCommand("free") + "##" println "==== Output from 'ps -l U tomcat-ssh-slave U tomcat U apache' ====" println "##" + sshHelper.runCommand("ps -l h U tomcat-ssh-slave U tomcat U apache") + "##" println "==== Output from 'df -H' ====" println "##" + sshHelper.runCommand("df -H") + "##" println "==== Output from 'top -b -n 1' ====" println "##" + sshHelper.runCommand("top -b -n 1") + "##" println "==== Close the connection and exit tomcat-ssh-slave shell ====" sshHelper.close() {{/groovy}} However, the Groovy.SshHelperClass script must be saved as a 1.0 document in order to call it at the top level via: "xwiki.parseGroovyFromPage("Groovy.SshHelperClass")". Is there a 2.0 syntax that works with parseGroovyFromPage()?
