Appengine error running GWT expense sample

[simonwhelan76]

Hi All

I just download the latest 1.1.1 and I'm trying to run the sample apps..

I'm using roo1.1.1 and GWT 2.1.1

but get this error.....does anyone know why?

I've followed this instruction in the pdf doc's for 1.1.1
"The GWT maven artifacts in your local maven repository should be removed so they can
be replaced with the latest versions. Make sure to delete ~/.m2/repository/com/google/gwt and
org/codehaus/mojo/gwt-maven-plugin."

But I was getting the same error even before I made these changes

any help is appreciated

[simonwhelan76]

I just reverted back to 1.1.0 and everything worked, so are other people finding this issue with 1.1.1?

As of now, I still have this issue with 1.1.1

[vmayakumar]

Hi Spring Roo Team,
I am getting this error when i run mvn gwt:run after the project is successfully created for Spring Roo using the information posted in Spring Roo website.

Any help would be highly appreciated.

[delirii]

Same problem here too.
I'm sad not being able to test what's new around GWT support.

[delirii]

Please note that simply deleting "gae" folders under "server" and "shared" seems to be enough to run the app.

[James Tyrrell]

@simonwhelan76, can you please delete the referenced folders from your local maven repo (that is, ~/.m2/repository/com/google/gwt and org/codehaus/mojo/gwt-maven-plugin) and rerun your script.

@vmayakumar/delirii, I am unable to replicate your issue. Can you please post some more info.

[simonwhelan76]

Thanks for the workaround delirii....it works after deleting those folders

simon

[simonwhelan76]

Hi James

I already done this, and got the exact same error. Well I actually renamed the folder instead of deleting and new ones were created. then after rerunning mvn gwt:run, the same error appeared.

Delirii work around, also worked for me on the expenses.roo project (I just deleted all folders named gae).

I'll be doing some more testing later on with other scripts (reverse eng and inheritance) and I'll post if I find anything

thanks simon

[vmayakumar]

Removing gae folders from shared and server worked.
I am able to run mvn gwt:run and see the output in browser when i click lauch in browser.

But when i run mvn tomcat:run and then open the browser using:
http://localhost:8080/movietickets then it opens the below url

http://localhost:8080/movietickets/A...nScaffold.html
Only "Loading..." text is shown nothing else is seen there. Am i missing something?

Regards,
V.Mayakumar

[vmayakumar]

Hi Spring ROO Team,
Same issue is seen when i working with samples which comes with Roo project itself.

works when i give mvn gwt:run
not working when i give mvn tomcat:run. Application is coming up but when i go to http://localhost:8080/extract i am seeing only "Loading...." text and nothing else. Am i missing something?

Regards,
V.Mayakumar
