Re: "can't find class file java/lang/Thread"
My guess is this, you don't have your classpath set. Make sure you have the following in your CLASSPATH environment variable. Path to the JDK classes. Path to any external jar files you might use (ie swing.jar) Path to your development tree (Ie for me it is the root of my jclass hierarchy) Finally a . , to get classes with no package in your current directory. IE, my classpath is usually somthing like CLASSPATH="d:/sdk/jdk1.1.6/lib/classes.zip;d:/special/swing.jar;e:/mydevt;." This will probably solve both of the problems you describe. ../Martin Aaron Brick wrote: > my JDK installation seems to be weird. i saw a previous post relevant to > this problem in the archive but the responses i saw weren't helpful. > > when i do "java HelloWorld.class" it complains about not being able to > find the class file - even if i pass the full path - until i do a > "-classpath `pwd`", or its equivalent. is this normal behavior? > > then - this is the step i have not been able to solve - it complains about > not being able to find a class file called "java/lang/Thread". well, i > have tried a large number of things with the Thread.class file, including > renaming it and putting its path in classpath, putting it in ad-hoc > subdirs in the java/classes dir (where i'm trying all this), etc. i just > can't get it to find the file. > > i mailed one member of this list and he told me to download some different > classes.zip file - however, it didn't appear to be on the russian server > he gave me. why the discrepancy, and what is the deal with this problem, > anyone? > > i have: > > JDK 1.1.6v2, glibc, i386 on Debian 2.0 (2.0.34), libc6. i don't have my > machine handy so i'm sorry i don't have the loader or X versions but i can > certainly supply them later. > > i would say this problem is of fairly high severity because it prevents me > from running any program at all! it may be that it is an isolated incident > but i sure thought the install went fine and my system is not weirdly > hacked or anything. > > thanks for your responses. > > aaron brick. >
Can't find class etc etc etc.
After seeing many of these messages roll by day after day I was thinking that perhaps we should create a mailing list faq of some sort that is sent to people when they first subscribe answering these basic questions? It's not that they are stupid questions, I think they are not well documented areas of Java, I just think that we may reduce the S/N ratio if we were to nail people with the answers before they ask the questions. If anyone is interested in this I could probably whip up a quick classpath/package use type thing. Comments? ../Martin

Re: DONT SEND ME ANYMORE STUFF!!!!!!!!!!!!!!!!!!!!!!!!!!!
Ok, this is getting way out of hand. Someone is using this mailing list to punish people who irritate them. I tried sending mail to the person who is listed as the mailing list maintainer and received no response so I'm going to publish the suggestion here. The java-linux mailing list needs to have a confirmation stage in the signup where the person has to respond to the subscription email with a unique #. This way we will hopefully cut down on these types of responses. I already send OGHOPAR instructions on how to unsubscribe btw. ../Martin [EMAIL PROTECTED] wrote: > STOP SENDING ME JUNK MAIL!

Because they fear Microsoft will use it as an excuse? They know that Microsoft will sue them for infringing on their look and feel. Much the same as Apple would probably defend the Mac L&F if Sun had not put the same restriction on that Swing L&F. There is a large difference between trying to prove that someone's L&F resembles yours and saying, these people made a carbon copy of our L&F and are letting people use it on other platforms. Why would you want to use the windows L&F anyways. Sheesh, ugly. Just my 2 cents. ../Martin Moses DeJong wrote: > This is total BS.

The problem isn't bad email addresses in the list, it's about some moron who likes to subscribe people who irritate him/her to a bunch of high traffic mailing lists like this one. The people who are subscribed usually have no idea what a mailing list is and just see it as unsolicited email/spam. This is becoming more and more common in my experience and the challenge/response system would get rid of it in a painless way. The footer in the email messages seems to have made a major dent in this problem, I think the challenge/response would kill it entirely. ../Martin -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

When I try to run Swing apps it locks up the minute a window is formed, if I use an AWT app it creates the window and starts drawing then locks. This could be due to the new rendering system.

The best way to speed up alot of swing components is to instrument them and see what kinds of usless operations it's doing and remove them. In the case of JTable some people here have said that you can increase the performance by writing your own renderer that doesn't try to render everything and the kitchen sink :) ../Martin -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
