Body
I am currently working on a sort-of-old web application. During a discussion with my boss, I mentioned that the application is using <code>Java 1.4</code>. Then, he interrupted me, then said that the project is actually using <code>Java 1.5</code>. I opened my workspace and show the reason why I said that the project is using Java 1.4. I navigated to <code>Project Properties > Build Path > Libraries</code>, listed here is JRE System Library[J2SE-1.4]. He then took the control then brought me to <code>Window > Preferences > Java > Compiler</code> then in the JDK Compliance section, Compiler compliance level has the value 1.5. Another thing that made me think that the project is using 1.4 is because, the <code>List</code> objects does not have parameterized type, and no warning is generated by Eclipse for them. Also, when I type <code>List<String></code>, eclipse gives me an error saying Syntax error, parameterized types are only available if source level is 1.5. This made me convinced that the application is using Java 1.5. But in my current position (junior developer) I need to make sure that my assumption is really correct before entering a debate with my boss. So, my question is, how do I really know the Java version that the application is using? What is difference between the Java version stated in <code>Project Properties > Build Path > Libraries</code> and <code>Window > Preferences > Java > Compiler</code> ?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
