Hi ,
I'm migrating Jetty6.1.19 to Jetty9.1.1. I'm using the
jetty-all-9.1.1.jar.
I'm facing NullPointerException in *WebAppProvider.start()* method. Below
is the code snippet where I'm facing exception. Since there is no
setContext() method, I have not set context explicitly.
Here the value of warpath is '*webapps*'. In my application the WAR file
exists in the path '
*pab/max/assume/msc/DEV/check/7.1.2_EV/webapps/axis2/WEB-INF/services/App.war*
'. I have attached the log. While scanning it throws NullPointer.
* this*.jettyWebServer =new Server();
WebAppProvider webAppDeployer=*new* WebAppProvider();
//webAppDeployer.setContexts(this.jettyWebServer); ->commented
setcontext
webAppDeployer.setMonitoredDirName(warpath); -->warpth is 'webapps'
webAppDeployer.setExtractWars(*true*);
webAppDeployer.setParentLoaderPriority(*true*);
*webAppDeployer.start();* -->NullPointerException while scanning.
*this*.jettyWebServer.setStopAtShutdown(*true*);
*this*.jettyWebServer.start();
* this*.jettyWebServer.join();
Could someone please help me what is wrong in this?. Do I need to
setContext manually.Please see the log attached.
Thanks,
Arun
