Hi,
Did a little debugging, and found out the following.
The reason for the issue is that
javax.servlet.ServletContext.class.getResource("{jsp/}resources/" + url)
returns null for some occasions. If the requested resource is coming
via javax.servlet_3.0.0.v201112011016.jar (ex. resources/XMLSchema.dtd)
then the resource gets loaded successfully. But if the resource is coming
via a different bundle (ex. jsp/resources/web-jsptaglibrary_1_1.dtd
resource in javax.servlet.jsp_2.2.0.v201112011158.jar), then the resource
cannot be located.
This is probably because the classloader of javax.servlet.ServletContext is
the javax.servlet_xxx bundle classloader. So, it can find the resources in
the javax.servlet_xxx bundle but not in other bundles as I see. Any ideas
how to fix this?
Following is the exact code -
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();
}
Thanks,
KasunG
