When it comes to importing a project into eclipse, the easiest way is to make use of the WAR file, which is provided in the SVN. We can directly import the WAR file using eclipse’s import mechanism.

1. To start importing, please go to File -> Import in eclipse and you will see the following dialog

   

2. Type WAR into the filter text then select the storewithdb WAR file you just downloaded and press next

   

3. Download the WAR file from https://zkbooks.googlecode.com/svn/trunk/zkessentials/storewithdb/storewithdb.war and place it into an accessible folder
4. On the WAR import screen browse for the WAR file and select it, the rest of the fields should be filled out automatically

   

5. Click finish and the WAR file will be imported
6. You should now have a clean project imported with no errors. At this point you can run the index.zul page on your server

   NOTE: Having imported if eclipse is registering a lot of errors then please see the section below labelled "Dealing with Errors"

   

Dealing with Errors

You may be seeing a lot of errors in your project say something along the lines of:

You should see errors referring to the fact that annotations are only available in Java 1.5. Right click on one of the errors and click Quick Fix:

On the following screen make sure "change project compliance to JRE 1.5 is selected and click finish:

Having done that we should have approximately 1 item left in the problems list. This should state that the Java compiler level does not match the version of the installed Java project facet:

Right click on the error and click quick fix as before. Then in the following screen select the item "Change Java project facet version to Java 5.0" and press Finish.

You should find that all the errors are now fixed and you can continue to run the application.
