Question

Reload WRS files without restarting Method Server?

Use Case: Updating a custom WRS domain.


Description:

Hello All,

 

I need to do quite a lot of trial-and-error on my custom WRS domain, mainly manipulating .js files. Restarting MS every time to pick up my changes is annoying.

 

Since those scripts are interpreted by Nashorn anyway, I thought... maybe there's some magic trick (e.g. calling some MBean method) to reload them without restarting MS every time?

 

Thanks!

    At the end of the day I didn't find a good solution, so I fired up my Java debugger and moved the code from JS files into Java classes instead. This way I can do trial and error on my OData endpoints without restarting the server thanks to JVM code hot swapping. The latter has its own limitations, but it takes away 90% of the pain associated with restarting the MS.
