the latest tomcat 7.0.50 has a problem when used through osgi (like eclipse)

[Johan Compagner]

this is because tomcat expects that the 2 jars servlet-api.jar and
jsp-api.jar are in the same classloader

because org.apache.tomcat.util.descriptor.DigesterFactory has this method:

 private static String idFor(String url) {
        URL id = ServletContext.class.getResource("resources/" + url);
        if (id == null) {
            id = ServletContext.class.getResource("jsp/resources/" + url);
        }
        return id.toExternalForm();
 }


thats kind of wrong, because ServletContext is in servlet-api but the
"jsp/resources/" dir is in the jsp-api.jar
so ServletContext should not be used to get the "jsp/resources" from the
js-api.jar

i think the code should be something like

 private static String idFor(String url) {
        URL id = ServletContext.class.getResource("resources/" + url);
        if (id == null) {
            id = JspContext.class.getResource("resources/" + url);
        }
        return id.toExternalForm();
 }


 So that at least the right classloader that also loads the JspContext is
used to get the jsp resources.
