If the .war file is being deployed to Jetty, then this wouldn't be considered "standalone" usage (which means running without a servlet container).

Instead, this appears to be just an issue where the Init servlet has not been installed in web.xml, or if that's impossible for some reason in this scenario, com.isomorphic.servlet.Init.go() has not been manually called.

Ah. Thanks for the clarification. Wasn't sure which category it fit in.

In any case, I do have the StartupServlet in my web.xml:

Code:

	<servlet>
		<servlet-name>Init</servlet-name>
		<servlet-class>my.app.StartupServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>

Given the stack trace, it seems to be called.

StartupServlet:

Code:

public class StartupServlet extends Init {
	@Override
	public void init() throws ServletException {
		try {
			MyDSGenerator datasourceGenerator = new MyDSGenerator(datasetFileName);
			DataSource.addDynamicDSGenerator(datasourceGenerator);
			super.init();
		} catch (Exception e) {
			throw new ServletException("Faied to initiliaze: could net generate datasources from dataset '" + datasetFileName + "'", e);
		}
		
	}
}

I am not manually calling com.isomorphic.servlet.Init.go(), I expect super.init() would do so? Could this be a problem with the DynamicDSGenerator?

**Isomorphic** · 17 Jul 2013, 12:52

super.init() would indeed do so.. too late. Call super.init() first.

Same exception with:

StartupServlet

Code:

public class StartupServlet extends Init {
	@Override
	public void init() throws ServletException {
		super.init();
		try {
			MyDSGenerator datasourceGenerator = new MyDSGenerator(datasetFileName);
			DataSource.addDynamicDSGenerator(datasourceGenerator);
		} catch (Exception e) {
			throw new ServletException("Faied to initiliaze: could net generate datasources from dataset '" + datasetFileName + "'", e);
		}
		
	}
}

Please double-check that result, it doesn't make much sense. If you're sure that's what's happening, please post the log from server startup until the exception occurs.

Updated StartupServlet to

Code:

public class StartupServlet extends Init {
	@Override
	public void init() throws ServletException {
		logger.error("Init called");
		super.init();
		try {
			MyDSGenerator datasourceGenerator = new MyDSGenerator(datasetFileName);
			DataSource.addDynamicDSGenerator(datasourceGenerator);
		} catch (Exception e) {
			throw new ServletException("Faied to initiliaze: could net generate datasources from dataset '" + datasetFileName + "'", e);
		}
		
	}
}

**Isomorphic** · 17 Jul 2013, 15:57

Look closely at the stack trace. The Isomorphic Init servlet calls super.init(config) from init(ServletConfig) as is required by the Servlets spec before doing anything. Your init() override (note: zero argument version) is then called by the javax.servlet.GenericServlet.init() - so your code still runs before SmartClient initialization has taken place.

To correct your code, override init(ServletConfig) not init().

Also, don't call Logger before super.init(config) or you'll introduce the same issue of calling framework code before initialization has taken place.

Finally, 8.2 is obsolete - please update to 8.3 or 9.0.
