Iterate over a Resource Bundle

[Mike Trinh]

Hello,

So i just made a Resource Bundle and i was wondering if it was possible to iterate over a RBD to get all te possible keys. I am able to retrieve the data by using

<fmt:message key="event" bundle="${type}" />

With a forEach i want to iterate over the bundle and get the different keys.

Greets,

Mike Trinh

Hi,

So not really a Hippo question but I'll give it a go.

With fmt setbundle you can put the bundle in a var and then you can call getKeys() (or maybe keySet()) and iterate over that set. Haven't ever tried this but it should work.

mvg,

Jasper

Hey Jasper,

Sorry for my late reply. Is it possible to do this is the jsp file?

Yes indeed.

<fmt:setBundle basename="some.bundle.name" var="someBundle"/>

<c:forEach items="${someBundle.keySet}" var="keys">
   ...
</c:forEach>

Something like that. Use keySet as it gives a Collection (Set) and getKeys gives an Enum which I don't think forEach can handle (but I'm not sure about that).

mvg,

Jasper

Hey Jasper,

I added the code to my jsp but im getting a stacktrace. I have tried both the keySet and getKeys

hmm...I think maybe you can't iterate over the Set then...you might have to convert this to a List. I wouldn't do that on the Jsp. You should either write your own tag or do this in the backing component class.

Come to think of it, iterating over a set is a bit strange as it doesn't have an order. If you care about order.

mvg,

According to [1], you cannot iterate with ResourceBundle#getKeys() like
other normal Java objects any more since JSP2.1.
You may still use the scriptlet code instead of JSTL tags.
