[rules-users] Problem with importing DrlParser and XmlDumper classes.

Hi, I have problem with importing and using DrlParser & XmlDumper classes. In Eclipse I get thoose communicate: "Discouraged access: The type DrlParser is not accessible due to restriction on required library [path hier]\drools-compiler.jar" I googled this problem (maybe not too long) but I haven't found a solution. I want to mark, that my Eclipse configuration is correct - I don't get error, but only warning. But this is annoying :) I tried to look in docs, but Drools 5.1 has no javadocs, and in Drools 5.0.'s javadocs there are no DrlParser and XmlDumper classes! Why? (In Drools 5.1. Expert User Guide 4.11.4 is written that Drools 5.1. uses those classes). I don't understand what's going on :) Greetings, tom.
