Struts2 plugin should not use System.exit() #113

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
If guice fails to create an object (possibly due to missing dependencies in
the classpath during runtime), it will call System.exit(1). I feel this is
a really bad thing for a library to do, as you risk taking down common test
environments if you do an error on deployment.

Example:
You have a test tomcat server that hosts 2 webapps, one of them is beeing
tested by 10 other developers, and the other is a webapp using Guice. You
create the war and deploy it. But the war is missing a jar in the lib
folder that you have in your development environment. When the app starts,
System.exit(1) gets called by Guice, and the entire Tomcat server is shut down.

This refers to the Struts 2 plugin. In the mean time, the plugin consists of one
class, so it's easy enough to patch your own version to do what you want. This 
plugin
(and probably Struts itself) needs some work.

Just saw this and wanted to comment. I prefer it to exit since Guice is acting 
as the
object provider for Struts. In all the cases I've seen, some configuration is 
missing
and therefore the application will not work unless that configuration is fixed.
Therefore, it seems correct that the application should be terminated since 
Guice
can't create an object that the application requires.

That's crazy. It should throw an exception, not shut down the JVM.

Agree, this really bottleneck is this plugin.

I suppose we could rethrow the CreationException every time Struts tries to 
create an
action, etc.

Just to chip in.  I definitely don't think this should be bringing down the
container.  Just an exception and the trace to stderr would suffice.  And then 
yes -
fair enough; an exception every time an instance is requested.

It is an extremely bad idea to shutdown the whole JVM due to one rogue app.

Hi we are using Guice with the struts 2 portlet plugin and having one portlet 
bring down a whole portal is really annoying. Defeats the whole purpose of 
enterprise portals. Please fix this.

FYI, the new version, Struts2Factory has a better behavior:
http://code.google.com/p/google-guice/source/browse/trunk/extensions/struts2/src
/com/google/inject/struts2/Struts2Factory.java

You can probably close this issue as being fixed in the next release.
