Re: StringTokenizer in GWT

Keep in mind that performance in the JVM is not the same as performance in GWT once compiled to JS.

In GWT, if you don't need regexp and only have one separator char, you'd probably better use indexOf and substring I guess.
If you need regexps, or have several separators, then using com.google.gwt.regexp (in the same way as indexOf) would work and should be fast.
…or you could use Guava's Splitter.

StringTokenizer is not depracatd though. There is also a good reason for this, as it is quite faster than the split method.

Check a comparison

I don't know for this error.

but from javadoc API you can read this:
StringTokenizer is a legacy class that is retained for compatibility
reasons although its use is discouraged in new code. It is recommended
that anyone seeking this functionality use the split  method of String
or the java.util.regex package instead.

So, try other method.
I'm sucessfully using split method.
