Subject Re: how to write json/xml output using struts 2 and rest + convention plugin
Date Thu, 04 Oct 2012 23:41:16 GMT
I'm not familiar with this application but simply look at the
documentation for the struts2-json-plugin, you can specify a json
result and you can specify include and exclude parameters (so you just
return the part(s) of your Action you want). In this way you could
define a new map, put a key of "results" with a value of "New order
created successfully" and return it quite easily. If the struts2
document is insufficient there are plenty of examples also on
StackOverflow, so take a look there too (Including many annotation
based examples).
