Help in using ArrayDeque

[haroldEugenio]

Hi,

I'm new in GWT designer and Java and I'm trying to create a GUI for my previous Solitaire project. The thing is, whenever I used ArrayDeque in y project, it shows this error even though I imported the java.util in my project:

[ERROR] [com.haroldGWT.solitaire.GWTSolHarold] - Line 7: No source code is available for type java.util.ArrayDeque<E>; did you forget to inherit a required module?

So I added this to my xml file to eliminate the error:

<inherits name="com.java.util.*"/>

The error for ArrayDeque disappeared but when I try to run my project, it shows a new error:

[ERROR] [com.haroldGWT.solitaire.GWTSolHarold] - Unable to find 'com/java/util/*.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?

Could anyone help me out please?

I really need the java.util since, without it, I can't even use StringTokenizer.

I would recommend posting general GWT questions to our (Google's) GWT Forum.

We would like to keep this forum focused on GWT Designer itself. Thank you.

P.S. it sounds like you need to read the GWT JRE Emulation Reference docs.
