Vaadin 7 RC2: Can't show Login page

Vaadin 6 / 7 / 8

Hi All,

I have a problem regarding to vaadin 7 and josso. I can build and deploy my project. JBoss started successfully . But when I try accessing my web page I’ll get the following error:

An error occurred at line: 17 in the generated java file
The return type is incompatible with JspSourceDependent.getDependants()

My web page can’t redirect to Login page because it can’t compile login.jsp to java class. With Vaadin 6, everything is ok and this bug happens when I migrate my code to vaadin 7.

My web.xml like that:

<?xml version="1.0" encoding="UTF-8"?>


Director

index.jsp disable-xsrf-protection true FORM /login-redirect.jsp /login-redirect.jsp 
<web-resource-collection>

I use JOSSO for authentication.

Thanks for help

I found that this bug won’t happen if I remove org.apache.jasper package in vaadin-client-compiler.jar.

You should not deploy the vaadin-client-compiler JAR - it is meant for widgetset compilation in a development environment, not for deployment on the application server.

Same scenario repeats again :slight_smile: Perhaps, you could mention in it book of Vaadin “2.3 Overview of Vaadin Libraries”.
I’m assembling my war file with ant script, not using eclipse.
