Java Forum / First Aid / February 2006Java Hangs up
Hi I have been using BlueJ as a compiler for about 4 months. But all of a sudden, for no reason, it decides not to work. I was using the application about a week back and it worked fine. Now the application opens up but when I click on a Menu Item(File > Open) it hangs up java and I cannot run anything else. My laptop fan starts spinning like crazy and until I end the javaw.exe file the fan spins like crazy like it's over processing and heating up. I don't think it's a Virus because I have done a virus scan with Norton and used registry mechanic also done a cleanup with Ad aware. I have uninstalled Java and reinstalled it. Currently I have jre1.5.0_06. I have also uninstalled BlueJ but that does not work. I have tried another java application which I use for another subject and it's the same when I click on a Menu item it hangs my laptop and the fan start to spin like crazy. Please help. I need to finish my assignments Thanks >the fan start to spin like crazy. I think you mean your CD-ROM drive not your case fan. Have you put your R: drive on your classpath or path?

BlueJ probably remembers the location where you last opened a file (perhaps you accessed a file from a floppy or CD recently?). Try to insert a (readable) floppy and CD(DVD) in your drives to see if that solves the problem. Regards, Roland Guys I have a laptop. I don't have a floppy drive and there is no cd in the DVD Rom drive that I have. I know for sure that it is the processor fan. I checked out the processes and javaw.exe shows 99% cpu usage. Its not only with BlueJ that I am having the problem. There is another applicatio that I use that gives me the same problem. When I compile it in BlueJ it runs fine and I can see the output. Its jsut that when I try to open a new project or another application that I was warking on.... its then that this happens. Like I click on file and open and it hangs up. > Guys I have a laptop.

Taylor, Regular Guy (1952-) This has just started some few days back. I happened to install Winamp the the one with the media player. I watched some TV serials on it and ever since that Java has been acting up. I don't think that this could be the issue. But I have uninstalled it. And it still hangs up. Javaw.exe shows 99% cpu usage. I even tried it without BlueJ. I use another Java application for another subject which gives the same problem. I have uninstalled java and Blue J and have the current versions of BlueJ and Java jre 1.5.0_06(Ver 5 with update 6).Which is the current version. I still cant get it to work.This is very wierd. I ran a virus scan and also registry mechanic and ad aware. IT still does not seem to help. I dont know what kind of a virus this is. I dont even know if this is a virus.

They exploit holes in the operating system to take control of a computer. Think of java as a computer inside your computer. They don't affect each other because if they did, then anyone could exploit a java program by exploiting windows. Encapsulation stops that cold.

I think I am may be hit by the same thing. My machine has been unusually slow. I upgraded Winamp recently too.

Try making a little test class with a simple output, save the test file, and try running it from the command prompt. If you get the output, it's not your java, it's BlueJ. BlueJ's more of a toy. Sorry but it is. My first semester in java was hard as hell because the teachers decided to start us off using BlueJ, then gradually turning us loose on JEdit. It f.cked me up bigtime. You learn to do things one way, then about a quarter of the way through, they switch and the java keeps getting harder. No. That's bad. They were trying something and I get it, but I didn't like it a whole lot at all.
