How to get an Image from mysql database, and display it froma java program? The title for this one was worse than the one you multi-posted to c.l.j.gui.! How many more of these messages are there? Please refrain from multi-posting in future. (X-post to c.l.j.p./g., w/ f-u to c.l.j.p. only) Andrew T. > The title for this one was worse than the one you > multi-posted to c.l.j.gui.!

At least the c.l.j.* groups. Is there a FAQ somewhere? > Anyway, seeing these frequent (re)offenders of usenet etiquette makes > me want to know more about common courtesy. At least the c.l.j.* > groups. Is there a FAQ somewhere? The general newsgroup etiquette (which you can find by googling for "newsgroup etiquette") applies here. In this case, Andrew was complaining about multiposting, and about the poor choice for a subject line. As for c.l.j.* in particular, there's http://www.riters.com/JINX but it looks like it's having some server problems right now (I get HTTP 500 errors). It's a wiki that some of the regulars in the c.l.j.* contribute to. In addition to information on Java, there's a page devoted to newsgroup etiquette in the specific context of the c.l.j.* tree (e.g. how to post a stack trace, etc.). - Oliver >>Anyway, seeing these frequent (re)offenders of usenet etiquette makes >>me want to know more about common courtesy.

There are many different ways to display an image in a java program--one of the easiest is to put it into a JLabel via an ImageIcon. Read the API (you have the API, right ?) for JLabel and go from there. As to how to get the image from a database, the critical question is how did the image get into the database? Is it in a blob? How is it encoded? Just select it like any other field and reverse the process. Most likely it will yield a byte array (in some format, gif, png, jpg) that you can use to instantiate the actual Image.
