copied!<p>Check out <a href="http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/rpc/RemoteServiceRelativePath.html" rel="noreferrer">documentation for RemoteServiceRelativePath annotation</a>, it explains pretty well what this annotation does. In your case, your service must be located at <code>GWT.getModuleBaseURL() + "stockPrices"</code> ... that means that if your GWT app is at <code>/mygwtapp</code>, then your service must be at <code>/mygwtapp/stockPrices</code>. It's up to you to install some service at this URL, usually by defining servlet implementing the service interface.</p> <p>You can use any other path instead of <code>"stockPrices"</code>, just make sure there is real service behind this path on the server.</p> <p>Your remote services need <em>some</em> remote path (entry point), either by using <code>@RemoteServiceRelativePath</code> annotation, or by setting it through <a href="http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/rpc/ServiceDefTarget.html" rel="noreferrer">ServiceDefTarget interface</a>. If service has no entry point, it cannot be called. (Remember: this path is URL on the server)</p> <p>For example, instead of using <code>@RemoteServiceRelativePath</code>, you can define your service without this annotation, and then when you instantiate async service proxy, you explicitly set path:</p> <pre><code>StockPriceServiceAsync stockService = GWT.create(StockPriceService.class); ((ServiceDefTarget) stockService).setServiceEntryPoint("/services/stock.service"); </code></pre>
