The application is packaged as executable jar, but it can't find the webapp directory that is included with the fat jar. so I must include the web app in the same directory as the fat jar.
I suspect the issue has to do with this code:
public void init(String host, int port) throws Exception {
logger.info("Starting Server bound to '" + host + ":" + port + "'");
String memory = Configurations.get("refine.memory");
if (memory != null) {
logger.info("refine.memory size: " + memory + " JVM Max heap: " + Runtime.getRuntime().maxMemory());
}
int maxThreads = Configurations.getInteger("refine.queue.size", 30);
int maxQueue = Configurations.getInteger("refine.queue.max_size", 300);
long keepAliveTime = Configurations.getInteger("refine.queue.idle_time", 60);
LinkedBlockingQueue<Runnable> queue = new LinkedBlockingQueue<Runnable>(maxQueue);
threadPool = new ThreadPoolExecutor(maxThreads, maxQueue, keepAliveTime, TimeUnit.SECONDS, queue);
this.setThreadPool(new ThreadPoolExecutorAdapter(threadPool));
Connector connector = new SocketConnector();
connector.setPort(port);
connector.setHost(host);
connector.setMaxIdleTime(Configurations.getInteger("refine.connection.max_idle_time",60000));
connector.setStatsOn(false);
this.addConnector(connector);
File webapp = new File("webapp");
final String contextPath = Configurations.get("refine.context_path","/");
final int maxFormContentSize = Configurations.getInteger("refine.max_form_content_size", 1048576);
logger.info("Initializing context: '" + contextPath + "' from '" + webapp.getAbsolutePath() + "'");
WebAppContext context = new WebAppContext();
URL webRootLocation = this.getClass().getResource("/webapp");
if (webRootLocation == null)
{
throw new IllegalStateException("Unable to determine webroot URL location");
}
URI webRootUri = URI.create(webRootLocation.toURI().toASCIIString());
System.err.printf("Web Root location: %s%n",webRootLocation);
System.err.printf("Web Root URI: %s%n",webRootUri);
context.setContextPath(webRootLocation.toString());
context.setBaseResource(Resource.newResource(webRootLocation));
context.setMaxFormContentSize(maxFormContentSize);
this.setHandler(context);
this.setHandler(context);
this.setStopAtShutdown(true);
this.setSendServerVersion(true);
// Enable context autoreloading
if (Configurations.getBoolean("refine.autoreload",false)) {
scanForUpdates(webapp, context);
}
// start the server
try {
this.start();
} catch (BindException e) {
logger.error("Failed to start server - is there another copy running already on this port/address?");
throw e;
}
configure(context);
}
I found what seems to be a possible solution is this SO, am I on the right path ? how would I fix this ?
Edit
I modified the code following advice given here and web searches, but now I get the following errors:
