The Technical Stuff.

The DB applet

The applet The applet (dbapplet) contains three class files (programs) and two modified instances of the Eadfrith applet written by Dr. Jonathan Goodman at the University of Cambridge. A graphical representation of the applet is shown in Figure 1. The actual applet is called PanelTest and basically reads files from the server. The user interface is mainly controlled by jcampViewer6. Ead2 and 3 display molecule coordinates and textbit displays any relevant information

Figure 1

1. The Ugric database is scanned for author entries.
2. The author entries are converted into a list and displayed in the jcampViewer6 panel.
3. The user double clicks an entry in the list and it's position in the list is sent back to PanelTest.
4. PanelTest reads the corresponding entry into memory.
5. The data is posted to jcampViewer6. Molecule coordinates are passed to the molecule viewers (Ead2 and 3)
6. Relevant data is displayed in the Textbit panel.
7. If NMR or IR data is requested, the file is read into PanelTest.
8. The JCAMP file is then displayed and manipulated in the jcampViewer6 panel
