Vaadin 7.6.0 and Jetty 6 (servlet 2.5 compatible)

Hi all,

is Vaadin 7.6.0 compatible with Jetty 6 (which, in turn, is only compatible with libservlet2.5-api)?

I just upgraded an application from Vaadin 7.3.x to 7.6.0 and I get this error in the log file:

Marco Zanon: Hi all,

is Vaadin 7.6.0 compatible with Jetty 6 (which, in turn, is only compatible with libservlet2.5-api)?

I just upgraded an application from Vaadin 7.3.x to 7.6.0 and I get this error in the log file:

 

Hey Marco, I am running 7.6.0 on Jetty 6.1.4, it's working fine for me without changing anything upgrading from 7.5.x!
 

Thanks Mario, then I know that Vaadin 7.6.0 is perfectly fine with Jetty 6. It must be a compilation problem then.

Thanks,
Marco

After hours of debugging, I found out that the problem was due to Tomcat7 (used locally when developing, in place of Jetty6 used on the vps) whose libraries in /usr/share/java probably interfered during the compilation.
Installing Jetty6 and removing Tomcat7 locally solved my problems.

Also, installing libjetty-java AND libjetty-java-extra made the logging system in Jetty6 started to work again.

Thanks,
Marco
