I have a copy of Tomcat both on my dev machine and my production machine. I have some code that looks for an image in a given location, and on the dev machine (which I set up), the code was working fine (the code takes that image and inserts it in the middle of a larger one that I'm drawing). I was wondering why the image wasn't appearing in the picture I was generating on the production machine (which I didn't set up--that contractor was around before I got on board and is no longer with us), and then realized I simply hadn't copied the image over to the appropriate directory on that computer. However, when I did copy the image into the right directory, it still wasn't picking it up, so I restarted Tomcat using the Win 2000 Server Services explorer. However, the small 1 KB image still wasn't being picked up and placed into the image I was drawing even though the code was the same as on the dev machine. I was baffled, and I stopped and started Tomcat a few times and then it finally started getting picked up! So then I deleted the image from the directory, restarted Tomcat, and the image was still being found even though it wasn't there! I restarted Tomcat again, and finally it wasn't being found anymore. In my code, I'm explicitly specifying that the image should be searched for in a pretty-hardcoded sort of manner every single time it's needed, but I'm thinking Tomcat might cache certain low-level operations in memory (or does Windows do it, perhaps?). I'm wondering if Tomcat might have remembered that that image hadn't been found before, so was returning some sort of empty file (though I don't think there were any exceptions, b/c I've searched for the expected println statements in my Tomcat stdout and stderr log files) every time after that...and if it was just in memory, then maybe stopping Tomcat from the Windows Services explorer doesn't get rid of Tomcat's stack memory (maybe Windows maintains that memory until you restart Tomcat, even it seems like that wouldn't be the behavior you'd expect).
I've included the code down at the bottom--it's pretty straightforward. I'd really like to know, because there have been times when I have tried to deploy updated JAR files and Tomcat just wouldn't pick them up. When a modified JSP isn't being re-compiled, I know to go search for the genereated Java code and class files in the work directory and delete them to force re-compilation, but I don't know what to do it to find a newly modified JAR file! Or in my other case, a newly "modified" image! Thanks for any clarifications! Here's the code I was referring to: String logoLocation = GlobalSettings.getSetting("imagedir") + "AE89x35.png"; try { //Image logo = Toolkit.getDefaultToolkit().getImage(logoLocation); javax.swing.ImageIcon logoIcon = new javax.swing.ImageIcon(logoLocation); Image logo = logoIcon.getImage(); //System.out.println("logoLocation is " + logoLocation); if (logo == null) System.err.println("logo is null, and toString gives " + logo.toString()); // Draw image boolean drawn = oCanvas.drawImage(logo, 185, 190, null); //System.out.println("drawn is " + drawn); } catch (Exception e) { System.err.println("Unable to find Airborne logo at " + logoLocation + ": " + e); } --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
