How about reading the documentation? http://code.google.com/intl/fr/webtoolkit/doc/1.6/DevGuideCodingBasics.html#DevGuideClientSide
The very first paragraph has the answer to your problem and instructs you to read the following part: http://code.google.com/intl/fr/webtoolkit/doc/1.6/DevGuideCodingBasics.html#DevGuideJavaCompatibility And ultimately this should precisely answer your question: http://code.google.com/webtoolkit/doc/1.6/RefJreEmulation.html =>There is no java.util.regex support in client-side code. You should use instead: http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html#matches(java.lang.String) If there's anything there that's not clear enough, feel free to ask for clarifications.
