How to extend Jahia class

by  mabouchacra »  2011/06/07 20:44

 

Hello,

 

I'm trying to fix some bug that I've found on Jahia, however I'm facing some difficulties.

For example : I've tried to extend the class Search_Engine.java in my template, so I've just created the package org.jahia.engines.search and copy the Search_Engine class on my package. I didn't modify anything in the class, but when I try to use the search engine it doesn't work I've got this error in the log :

So did I do something wrong? Or is it that it's just impossible to extend Jahia classes?

 

Cheers,

Marc.

    Hello Marc,

    where have you put your compiled class? What target Java level have you used for the compilatioin (1.5, 1.6)?
    You could also try to delete your compiled JSPs (in the Tomcat's work folder) and try again.

    Kind regards
    Sergiy

    Hi Sergiy,

    I put my class in the template, so after the template deployement the compiled class was put in the ROOT/WEB-INF/classes folder.

    Also I've tried to remove the compiled JSP as you said but the result is the same.

    About my java environment I'm working and compiling whith java 1.6.

    Cheers,
    Marc.
