GWT converts java source code to javascript that will be run on a web browser. In doing such GWT has to live by the restrictions set by the web browser.
GWT client code doesn't support java.io because javascript doesn't have that functionality.. Some 3rd party stuff can be made to work but there are conditions. basically you can use any third party parts that you want on the server but you need to stick to what is emulated by GWT for the client. Have a look at this. http://code.google.com/docreader/#p=google-web-toolkit- doc-1-5&s=google-web-toolkit-doc-1-5&t=RefJreEmulation Have a search of this list as there have been some rather lengthy explanations of this topic. -jason On Jan 12, 2009, at 8:06 AM, Mark wrote: > > I want to make a web tool base on gwt UI.
