Re: Seeking help for a HotSwapAgent's Wicket plugin

[Thomas Heigl]

Hi Francesco,

I faced the same situation last week.

I wrote a Wicket plugin that clears the Localizer cache. It does not clear
the resource bundle cache because I use Spring's ReloadableResourceBundle,
but that should be very easy to add.

Configuration is a little more difficult than with JRebel. I had to add
src/main/resources as extraClasspath for some reason, to get it to reload
HTML and property files.

Here is a gist with my Wicket plugin and my working
hotswap-agent.properties:

Best,

Thomas

Seeking help for a HotSwapAgent's Wicket plugin

[Francesco Chicchiriccò]

Hi all,
at Syncope we recently switched from JRebel to HotSwapAgent, mostly because the 
MyJRebel program has ended.
All works quite well for Java classes, but we do have issues with HTML and 
properties files (for Resource Bundles) used by Wicket.

Please consider that we do package our Wicket application as JAR with 
web-fragment [1], and HTML and properties files are kept under 
src/main/resources [2].

I have started building a Wicket plugin for HotSwapAgent following the 
instructions at [3] and the samples at [4]: the MyFaces plugin [5] looks 
promising, at least because it says that it's clearing out the Resource Bundle 
cache.

So my question is: assuming that HotSwapAgent correctly replaces the HTML and 
properties file in the classloader, how can I trigger Wicket to reload?

TIA
Regards.
