Hi. I am new to java. I have taken two introductory classes, which taught me very little, and we only worked with applications. Now, my job needs me to be able to write a program as soon as I can. I need it to be deployed on an iSeries, read input and use SQL to search and retrieve results from a datafile or two, display the results on a different screen, and run in internet explorer (I guess that means an applet). I really don't know where to start. I'm reading this teach yourself Java in 21 days book, but it seems like I'm learning about everything but what I need to (arrays, casting, etc.) I need a resource that will explain the necessary concepts as if to a beginner. Is there any of this out there, or can you guys offer any suggestions?
