Re: upgrade gwt 2.7 to gwt 2.8.1 not working

I found why this problem happens

HTTP ERROR 403

Problem accessing /Darimpo.html. Reason:

    !Secure

Powered by Jetty://

it happened because i used ssl in my web.xml like this

    <security-constraint>

        <web-resource-collection>
            <url-pattern>/*</url-pattern>
        </web-resource-collection>
        <user-data-constraint>
            <transport-guarantee>CONFIDENTIAL</transport-guarantee>
        </user-data-constraint>
    </security-constraint>
when i remove this code my app worked 
but i need this code so what i can do?

wwoowwww thank you 
this worked for me 
for the second problem i removed google map and this is worked for me (i did this in past and it not worked but now it work i do not know why but now it work)
for the first problem the solution is the order of libs. i go to the orders of libs and put the gwt before google app engine and it worked.

but now i have another problem when i run the code i get exception like this:

Check your classpath, you probably have Servlets API in version 2.x (2.4, 2.5). This method was added in Servlets 3.0 (https://docs.oracle.com/javaee/7/api/javax/servlet/ServletContext.html#getJspConfigDescriptor--), and Jetty 9.2.14.v20151106 (the version that GWT uses) actually needs Servlets 3.1.0 (https://search.maven.org/#artifactdetails%7Corg.eclipse.jetty%7Cjetty-project%7C9.2.14.v20151106%7Cjar)
(GWT 2.7.0 was using Jetty 8.1.12.v20130726, which BTW already needed Servlets 3.0 https://search.maven.org/#artifactdetails%7Corg.eclipse.jetty%7Cjetty-project%7C8.1.12.v20130726%7Cjar, but could have maybe worked OK with Servlets 2.5 – I doubt it, maybe you changed the order of JARs in your classpath when upgrading; GWT 2.7 used to bundle the Servlets API into gwt-dev, and this has changed in 2.8.1, when retrieved from the Central Repository)

2) when i try to compile the project i get this exception

As someone told you already on StackOverflow, HasMetaData has been removed from GWT 2.8, after being deprecated for more than 8 years! (https://github.com/gwtproject/gwt/commit/aa1113205c3c2494d29a8c74cb368fdb497249f8)
You need to either update your gwt-maps dependency (if possible, but it's been unmaintained for years too, I have no idea of its compatibility story) or switch to another Google Maps integration library (or write yours using JsInterop).
