    Have you tried this [Adding jar to Eclipse](https://stackoverflow.com/questions/3280353/how-to-import-a-jar-in-eclipse) – Marc-Anthony Jan 24 '19 at 20:22
  • I'd really suggest to use a package manager if you can. It downloads published jars and adds them to the classpath automatically. Two popular choices are maven and gradle. Eclipse has plugins for working with both of them – Coderino Javarino Jan 24 '19 at 20:25
  • So your Jar is in the referenced projects, so you should be fine. Have you just cleaning and rebuilding your project? – entpnerd Jan 24 '19 at 20:26
  • i tried to clean the project and rebuild it but that didn't work , i'm interested in what you said about the package manager, what do i need to do to get these plugins ? – Yasser Bouaabane Jan 24 '19 at 20:47

rs2xml.jar doesn't contain the needed java class. The most probably reason is that it was built incorrectly.

As you may see it contains 'src.net.proteanit.sql' which is empty.

So to fix the problem the jar should be rebuilt

  1. The package should not include 'src' prefix
  2. The DbUtils class should be truly included into it.

  • I guess DbUtils is included in the jar, and i tried to add it in the build path but still i faced the same problem, it doesn't recognize the jar at all. – Yasser Bouaabane Jan 24 '19 at 20:32
  • Try unpacking the jar to see its contents. Eclipse shows that the 'package' src.net.proteaint.sql is empty (by white background color). In any case the 'src' prefix is most likely also wrong. – leokom Jan 24 '19 at 20:38
  • So i deleted the src file and tried to add it to the libraries using "add an external jar", then tried to import it " import net.proteanit.sql; ", but it didn't work either. – Yasser Bouaabane Jan 24 '19 at 20:50
  • does Eclipse show net.proteanit.sql package as not empty? In the package explorer it should look brown similarily to org.jdom.xpath and be expandable - so that you can see its contents – leokom Jan 24 '19 at 20:51
  • Look at the jar file, the second package is what i want to import net.proteanit.sql and it is not empty it contains classes and DbUtils in one of them. – Yasser Bouaabane Jan 24 '19 at 20:59
  • try Project - Clean to make Eclipse refresh the project – leokom Jan 24 '19 at 21:23
