  • Session error [DWR + Spring 2.5.4 ]

    Hi there,

    I just migrated to Spring 2.5.4 from Spring 2.0.8.

    In my web app I got integrated DWR 2.0.4. Since I've migrated I got an error message coming from DWR when invoking succesive DWR requests. My web application gets a pop-up error message stating SESSION ERROR.

    Then checking tomcat logs I've found the following message:

    16:59:55,045 ERROR Batch,http-8080-Processor23:75 - A request has been denied as a potential CSRF attack.

    Doing my research, I've found that this error comes from DWR jar.

    But I don't understand why this didn't happen with Spring 2.0.8. It was all good.

    Does anyone know where the problem maybe? Or if someone came across this problem how can it be solved?

    Any help would be appreciated as I don't know where or what to look at.

    My configuration is:

    Tomcat 5.5.23
    Spring 2.5.4
    DWR 2.0.X
