upgrade gwt 2.7 to gwt 2.8.1 not working

[Gal Lavie]

Hi everyone

I develop application in gwt and google app engine.

until now i used with gwt 2.7 lib and google app engine 1.51 lib

i try to upgrade the gwt 2.7 to 2.8.1 lib

and i have 2 problems now 

i hope you can help me

1) when i try to run the project i get exception in devModeBase.class file in run method 

this is the log of run + exception:

thank you every one

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)

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).

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:

maybe you know why?

HTTP ERROR 403

Problem accessing /Darimpo.html. Reason:

    !Secure

---

Powered by Jetty://

thank you again

[Gal Lavie]

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?

Oh, I had missed the part where you said you're using App Engine.

Aren't you supposed to use the AppEngineLauncher with DevMode then? (AFAICT, it's no longer supported though, so you'll actually want to run the AppEngine server and then run DevMode in "no server" mode, or use CodeServer instead)

See https://gwt-plugins.github.io/documentation/gwt-eclipse-plugin/servers/AppEngine.html

Thanks! You answered this question over a year and a half ago, but I just hit this very problem while converting an app from 2.7.0 to 2.8.2. (Why now? With Oracle cutting off Java 8, we moved to Amazon Corretto, and found some old imaging stuff that would not work with OpenJDK. As long as I was correcting this and moving from Java 6 to OpenJDK 8--and with this weeks Canary problems in mind--I decided to bump GWT as well.)

Interesting what you say about Jetty in 2.7.0: I've never had a problem with Servlet spec 2.5 and GWT 2.7.0 (this app has used 2.5 for years). 

From my testing with Tomcat 8.5, I can still use servlet 2.5 or 3.0 in the web.xml header of the deployed app. Have you seen issues in deployment? I ask because we've one customer who runs WebLogic and their current version--12.1.3.0.0--only supports up to 3.0.

This was a classpath issue, not a webapp one. You never package the servlet APIs in your WARs, and even if you did, the server would use its own version and ignore yours. So as long as you don't use newer APIs that the target server doesn't support, you're safe.

The problem is if you put an older API in the server's classpath (in the case of GWT, the devmode classpath), like if you shadowed/replaced WebLogic's own servlet API with another one.

Fwiw, separating client and server code into separate "modules" (separate classpaths: only including client-side dependencies in the devmode classpath, leaving server-side dependencies to the webapp's WEB-INF/lib), something I've been advocating for years, generally solves these conflicts.
