Hey everyone,
we are developing GWT applications using maven, gwt-maven-plugin,
Eclipse 3.5 EE and m2eclipse. We are currently having some problems
setting up a proper run configuration (based on mvn gwt:run goal) that
seem to come from wrong paths to resources.
Apparently the <runTarget> tag is used to specify the resource to
launch in DevMode. As the documentation says, one can insert the full
module path there appended by the resource ("/Application.html") IF
that resource is located in the modules "public" folder. The plugin
then replaces the module path by the value of the rename-to directive.
Now GWT compiler creates a folder named like the rename-to directve
value and puts all generated resources in there, namely the generated
js-files and the gwt stuff.
BUT gwt-maven also puts all other resources in there that is your
Application.html which includes the <script> tag and other files like
Application.css for example.
Now in order to make the application work in Tomcat (our deployment
target) one needs to adjust all resource references starting from the
<welcome-file> in web.xml to all other includes in the
Application.html as ther are the <script> tag and css-includes to
match the location inside the folder named after the rename-to
directive.
But with this configuration the application can not be run in DevMode
since DevMode prepends the rename-to directive to all GET request
which leads to 404 when requesting the nocache.js (and css and so on,
but missing nocache prevents everything else from happening; only
white empty html). It requests them from "rename-to/rename-to/rename-
to.nocache.js", where rename-to is what you entered in your modules
rename-to directive. The correct path would be "rename-to/rename-
to.nocache.js"
Now where is the problem? How can I configure the runTarget or the
paths GWT creates to be the same in DevMode as deployed on Tomcat?
Thanks in advance.
Andreas
P.S.: I remember pure GEP-Projects placing the application html in the
root directory of the web application, but gwt-maven does not, maybe
that is one reason it conflicts. In our case it even is a pure GEP
project we converted to a gwt-maven one. gwt-maven also uses
index.html and simply redirects to the application html.
