Primary Goal To provide a comprehensive staff directory with photographs.

Issues What data to display? Storage vs. Speed What language to use? What framework to use?

Accomplished So Far Created a view to supply the data elements Use of Oracle Intermedia 10g Opted for speed Language – Java Framework – Struts

What Happened Had base code written in Banner6/Oracle 9 Tried to import images in Oracle 10 – errors Oracle 10 does not seem to handle BLOBs Needed to migrate everything to Ordimage

Processing Steps Copy images to UNIX directory Java code to read the file names into a table Procedure to load images & set image properties Procedure to resize images & store – fixedscale= – fixedscale= Cleanup

The Java Code CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED HACCINST1."DirList AS import java.io.*; import java.sql.*; public class DirList { public static void getList(String directory) throws SQLException { File path = new File( directory ); String[] list = path.list(); String element; for(int i = 0; i < list.length; i++) { element = list[i]; #sql { INSERT INTO DIR_LIST (FILENAME) VALUES (:element) }; }

Loading the images INSERT INTO IMAGE_XFR_TABLE VALUES( image_id, ORDSYS.ORDIMAGE.init('FILE','IMAGEDIR',filename), NULL); SELECT img INTO myImage FROM IMAGE_XFR_TABL WHERE ID = image_id FOR UPDATE; --- we import the image into the table using a buffer (ctx). myImage.import(ctx); --- we do a setproperties on the object which sets the --- attributes of the object such as mimetype from the metadata in --- the image file. myImage.setproperties(); UPDATE IMAGE_XFR_TABLE SET img=myImage WHERE ID=image_id;

The Move Code PROCEDURE move_photo(pidm in number, initialImage in ORDSYS.ORDImage) IS myNewImage ORDSYS.ORDImage; myThumbnail ORDSYS.ORDImage; tempImage ORDSYS.ORDImage; BEGIN INSERT INTO gztpoto(gztpoto_pidm,gztpoto_image,gztpoto_activity_date, gztpoto_user, gztpoto_thumb, gztpoto_status) VALUES(pidm, ORDSYS.ORDIMAGE.init(), trunc(sysdate), USER, ORDSYS.ORDIMAGE.init(),NULL); SELECT gztpoto_image, gztpoto_thumb INTO myNewImage, myThumbnail from gztpoto WHERE gztpoto_pidm = pidm FOR UPDATE; tempImage := initialImage; tempImage.processcopy('fileFormat=JFIF fixedscale= ', myNewImage); tempImage.processcopy('fileFormat=JFIF fixedscale= ', myThumbnail); UPDATE gztpoto SET gztpoto_image = myNewImage, gztpoto_thumb = myThumbnail WHERE gztpoto_pidm = pidm;

Needs to be done. Figure out how to display the images Finalize new code Migrate JSPs to Struts Migrate Guard-Card database to Oracle – Create triggers to move information – Create Scripts to copy & resize photos Archiving images(5 year plan)
