I have a project opened in eclipse, its a java web application. In eclipse I can see that there is a red cross sign with my project name, On expanding my project I can see many files have the same red cross sign.

What does this cross sign means in eclipse? Is it showing some compilation error? if error how can I see the error? Also what does that triangle icon means?

enter image description here

Please check the screenshot above and see the cross and triangle signs…
