How to create War file after complied GWT project?

[Tom]

I am quite confused about this area.

Ok, I finished my app in eclipse so I clicked "GWT Compile Project"

...
   Compiling permutation 4...

   Compiling permutation 5...

   Compile of permutations succeeded

Linking into C:\Users\myP\war\myApp

   Link succeeded

   Compilation succeeded -- 289.644s

Now seem C:\Users\myP\war has many files like .log & folders like myApp, images, WEB-INF, myP.css, myP.html, style.css

Then how to create war file from C:\Users\myP\war folder?

[Davide Micheletti]

zip the war folder and load it into the server and change the extension to .war.. ;) 

or use maven plugin.. 

if you use Eclipse:

right click on your project -> Export -> War File

is your project a Web Project?? 

Best way is to create a new Web project and copy data from old project into web project.

if not works see this:

first zip

second rename to myApp.war

third load into webserver

fourth run

if you use a tomcat server use his webapp manager and deploy your proj

Desployed failed do u know how to chenge the max config?

[Davide Micheletti]

Go to the web.xml of the manager application (for instance it could be under /tomcatX/webapps/manager/WEB-INF/web.xml.
Increase the max-file-size and max-request-size

   <multipart-config>

      <!-- 50MB max -->

      <max-file-size>52428800</max-file-size>

      <max-request-size>52428800</max-request-size>

      <file-size-threshold>0</file-size-threshold>

92Mb?! and without using any build tool or dependency management?

Maybe pass "-deploy <some folder>" to the GWT compiler when compiling your app and clean-up the WEB-INF/deploy folder.

Also make sure you're not bundling gwt-user and/or gwt-dev.

[Davide Micheletti]

However 92 MB is really really BIG.. try to clean your project..

92Mb?! and without using any build tool or dependency management?

Maybe pass "-deploy <some folder>" to the GWT compiler when compiling your app and clean-up the WEB-INF/deploy folder.

Also make sure you're not bundling gwt-user and/or gwt-dev.

Hi Thomas, I got gwt-dev.jar & gwt-user-2.5.0.jar in myApp\war\WEB-INF\lib. The reason is that is i don't have these 2 jar files in myApp\war\WEB-INF\lib, then everytime I run myApp in Eclipse, eClipse warning that it can find class in the eclipse clathpath but not from myApp\war\WEB-INF\lib.

I remembered a few months ago, you said if we saw these kinds of warning in Eclipse then we need to include the jar file into myApp\war\WEB-INF\lib otherwise it may not work after deployed.

Now, if I remove gwt-dev.jar & gwt-user-2.5.0.jar in myApp\war\WEB-INF\lib & deploy myApp then will myApp running ok?

You should not need to deploy gwt-dev or gwt-user, and you must not deploy them (for many reasons, including the exception you're seeing here).

You might need gwt-servlet.jar though.

Or if you use some third-party lib that happens to be bundled within either gwt-dev or gwt-user (e.g. ICU4J, Commons Collections) then you should grab JARs for those deps and put them in your webapp.

[Tom]

Thax you very much Thomas, I understand now cos we already generate gwt Java code into Javascript so we don't need them right. Ok I got it
