Modules Causing "SEVERE" Exception on Startup

[enguyen]

Hello, all. I'm piloting OpenMRS at a hospital in Goma, Congo, but I'm having a lot of problems getting it up and running. Any help would be much appreciated.

My current issue is that any modules I install seem to kill my installation of OpenMRS. For example, if I copy either formentry-2.5.omod or clinicalsummary-2.0.omod into my .../modules directory and restart Tomcat, then I get the following in the logs:

Code: Select all

  SEVERE: Exception sending context initialized event to listener instance of class org.openmrs.web.Listener
  java.lang.NullPointerException
   at org.openmrs.module.ModuleFileParser.parse(ModuleFileParser.java:192)
   at org.openmrs.module.ModuleFactory.getModuleFromFile(ModuleFactory.java:245)
   at org.openmrs.module.ModuleFactory.loadModule(ModuleFactory.java:71)
   at org.openmrs.module.ModuleFactory.loadModule(ModuleFactory.java:57)
   at org.openmrs.module.ModuleFactory.loadAndStartModules(ModuleFactory.java:118)
   ...


The same error comes up for both modules. At that point, visiting any URL within the app returns a 404. Any advice? I'm running OpenMRS v1.1.0 with the openmrs-demo-sql-1.1.0 loaded. The app comes up just fine without any modules added.

I'll have plenty of questions once the app is up and running, as well. But first things first...

Thanks for all your help, and for everyone who has contributed to this software.

Best,
Eric Nguyen

The modules seem to be corrupted somehow. Have you tried redownload the modules? Perhaps building from source would do the trick.

How did you get your war file? The main download section, a nightly build, or a compilation from alpha source?

The main download comes with formentry module 2.4 I think. Look in Tomcat 5.5/webapps/openmrs/WEB-INF/coreModules. Try deleting that and restarting tomcat.

Bingo! Corrupted module files. I'd downloaded these from the site (e.g. https://dev.openmrs.org/modules/view.js ... =formentry), and for some reason, the download had been signaled as completed even though it was not. I downloaded the same file a few times, and each time the file size was a bit different. The largest file of them all seems to be working

Note that with Firefox (which is what I'm using) the downloads window doesn't know how large the file is supposed to be, while it's downloading. It just pulls down the file without being able to display any sort of status bar.

Thanks, Ben, for pointing me in the right direction.

Glad to hear things are moving forward again!

Thanks for the heads up. I corrected the module repository download screen. Try downloading another module and see if it will successfully complete on the first try.

Works! The file size is displayed correctly and everything. Thanks, Ben.
