Question

Hi I have this code in my gwt app which purpose is to chage to URL as follows:

public void goToSignUpPage(boolean isDeployed) {
    String url = (isDeployed == true ? "signup.html" : "signup.html?gwt.codesvr=127.0.0.1:9997");
    Window.Location.replace(url);

However what happens it redirects into this URL:

http://127.0.0.1:8888/mygwtapp/signup.html?gwt.codesvr=127.0.0.1:9997

Where the working URL is this:

http://127.0.0.1:8888/signup.html?gwt.codesvr=127.0.0.1:9997

BTW, mygwtapp is the gwt module named defined in MyGwtApp.gwt.xml

<module rename-to='mygwtapp'>

Any ideas why the URL is appended by the gwt module name? Any way to fix this?

All you needed was to add in GWT.getHostPageBaseURL() to get the full URL for your web application without it appending to the module name.

Try this out:

public void goToSignUpPage() {
    String url = GWT.getHostPageBaseURL() + "signup.html";

    if(!GWT.isProdMode()) {
        Window.alert("We are in development mode!");
        url += "?gwt.codesvr=127.0.0.1:9997";
    }

    Window.Location.replace(url);
}

I’ve also removed your parameter “isDeployed” and replaced it with GWT.isProdMode() within the method to check if you’re in production or development mode.

With a paramater:

public void goToSignUpPage(Boolean isDeployed) {

    String url = GWT.getHostPageBaseURL() + "signup.html";

    if(!isDeployed) {
        url += "?gwt.codesvr=127.0.0.1:9997";
    }

    Window.Location.replace(url);
}

Hope this helps!
