Subject [jira] [Closed] (EDGENT-249) DevelopmentProvider on PI gets NPE
Date Thu, 02 Mar 2017 22:06:45 GMT

     [ https://issues.apache.org/jira/browse/EDGENT-249?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Dale LaBossiere closed EDGENT-249.
    Resolution: Cannot Reproduce

I'm not seeing an exception with current Edgent code (~v1.1.0) and a trivial sample app.

A browser on OSX pointed at the console's port on the Pi works great; everything renders fine.

However when I started a browser on the Pi, several things didn't render. 

I'm closing this "NPE" defect. I've created EDGENT-392 to track the rendering-on-Pi issue.

> A user contacted me about a NPE they were getting when starting an app that uses the
DevelopmentProvider on a Raspberry PI.  The code runs fine on a non-PI system.  They said
it was a vintage 24Aug copy of the code.
> The NPE was occurring in ServerUtil.getTopDirFilePath() on the line:
>         return jarFile.getParentFile().getParentFile().getParentFile();
> Don't know what ServerUtil.getPath() is returning on the PI but it didn't satisfy the
expectations above.  They were going to try to get me additional output (the path returned
by getPath()) but I haven't heard back yet.
> The edgent java8 release image was installed on the PI as demonstrated by the successful
workaround I was able to give them to get them going:
> Workaround: add a JVM system property when you launch your app:   
>    -Dedgent.test.top.dir.file.path=<root-of-the-edgent-java8-dir> 
> e.g.,
>   -Dedgent.test.top.dir.file.path=/edgent/java8
