The “Order and Export” tab in “Java Build Path”

Question

What\'s the use of \"Order and Export\" tab in \"Java Build Path\" dialog box?

Answer 1

There is one case where-in I found this useful. I had to use a sun.* class of an IBM jar. This class was also present in local jre, but my requirement was to use IBM's class. But by default,the compiler would refer the local jdk class only. In the eclipse order and export tab, I moved the external jar ahead of the JRE lib. Now, the compiler would refer to the class from IBM jar instead of local JRE.
