DB Applet

Ugric splitter

To allow the download of the various parts of the database (jcamp files, mol files etc.) the central ugric database is first treated with a Java application called UGsplit (Ugric splitter) This program reads in the original database and strips out all molecular and Jcamp files and replaces them with references to the files location. This achieves three purposes:

1. Checks that the database is in fact conforming to the Ugric DTD
2. Makes the Ugic database much smaller (and therefore more rapidly read).
3. Allows the applet to use the browser to download various parts of the database to the client machine.
4. In conjunction with a server side script allows the imediate viewing of uploaded files - see Authoring tools.

UGsplit Vs 1.0 can be downloaded:

To use UGsplit

On a PC:

• copy the Central Ugic file to the same directory UGsplit is stored in.
• At the MSDOS prompt type javac UGsplit followed by the file name.
• The molecule files, jcamp files and the final ugric file (Ugricfin.ugr) will now be in the same directory.

Hint: it is a good idea to keep UGsplit in the same directory as the database applet.

The applets then need to be kept in the same directory as the database. The files needed can be downloaded (to download right click the following links and choose save link As (or equivalent) Macintosh users click and hold until the menu appears:
