classpath
Hi all,
I create a JVM inside my C code. but when running,
it said that Can't find Prog Class as what i witten in my c code.
cls = (*env)->FindClass(env,
"Prog"); if (cls == 0)
{ fprintf(stderr, "Can't find Prog
class\n"); exit(1);
How to set the classpath until c know where to get
prog.class. I put it in /root/jni and set the following:
options[1].optionString =
"-Djava.class.path=root/jni/Prog"; // user classes
Why still can't find Prog class?
Thanks in advance
soonho
RE: font problem
"Font specified in font.properties not found [--zapf dingbats-medium-r-normal--*-%d-*-*-p-*-adobe-fontspecific]" If this is (or similar to) the error you are getting the fix is simple. Copy "symbol.ttf" to the /j2re1.3/lib/fonts directory add the following line to "fonts.dir" "symbol.ttf -urw-symbol-medium-r-normal--0-0-0-0-p-0-ad obe-fontspecific" You also have to change the number at the top of fonts.dir to 13, as there are now 13 fonts. You can get symbol.ttf from a windows machine. Or contact me & I'll send it.

Messed up swing windows
I often have a problem where my Swing windows get created messed up. I've attached a couple of gifs to show what I mean. This usually (if not always) happens with a frame or dialog is being created and is not 100% reproducible. My guess would be that it is the result of a race condition but I have no idea how to work around it. My solution to date is to simply kill that application and start it again. It happens under both the latest Blackdown and Sun 1.3 jdks (and all other JDKs in the last 6 months or so). I don't think it happens under windows. Is this a known problem, or something I'm doing wrong with Swing? My apologies if sending images to the list is taboo, but it's the best way to show what is happening. <> <> messedup.gif ok.gif
Servlet API classes - where to place them?
Hi, I started to work with servlets and found that I need to download Servlet API classes - servlet-2_2b.zip package. I have few questions about this package. 1. Does it run on Linux? 2. Where jdk directory structure I have to place it in: a) /jdk/jre/lib/ext b) should I create /jdk/jre/lib/classes directory and place them over there ?

If you just need the library to compile your own classes, you can install it as an extension or put it in your classpath. If you want to run a servlet environment - something that will handle HTTP requests and run servlets - then you need to choose and run one. You have many choices here: for example, there's the Tomcat servlet engine you can use with Apache (http://jakarta.apache.org/tomcat/), and there are pure-Java Web servers such as Jetty (http://jetty.mortbay.com/).

Re: Servlet API classes - where to place them?
Thank you Nathan, I use Tomcat server. However, I still need to compile my servlet with Java servlet package. Here I found some unexpected installation feature. I placed servlet-2_2b.zip on my CLASSPATH and it did not work wherever I placed it. After some trials, I unzipped it and to my surprise found server.jar file in it! Also, I could not find any instructions on the Sun's site how to install it. After I discovered server.jar file I placed it in the jre/lib/ext directory and it started to work.

RE: Messed up swing windows
I have a situation right now where I am experienceing it more often than not when trying to bring up a JOptionPane. I've tried a number of things, such as making sure that I do in the SwingEvent Thread, making sure I do it not in the Swing event thread, calling yield before i create the dialog, all with the same result. I then switch to the IBM 1.3 jdk and have not experienced the problem. I thought that this might indicate that hotspot is to blame so I went back to the Blackdown jdk and tried it with -Djava.compiler=none but it still happens. > -Original Message- > From: Miloslaw Smyk [mailto:[EMAIL PROTECTED]] > Sent: Thursday, February 08, 2001 2:57 PM > To: Martin, Stephen; [EMAIL PROTECTED] > Subject: Re: Messed up swing windows > > > "Martin, Stephen" wrote: > > > > I often have a problem where my Swing windows get created > messed up.

I am a linux geek and I regularly see this sort of behavior in apps written by inexperienced Java developers running windows. It seems that the heavyweight peers behave differently between *nix and Windows. Some actions which are separate method calls in Java are hardcoded in Windows peers. For instance, the action of de-iconifying a window does NOT automatically bring that window to top in a *nix window manager, so the method must be called to force it to the top. On Windows, de-iconifying a window brings it to the top automatically. So, many Java apps developed on Windows and not tested on *nix will behave oddly because necessary Java calls were not made. Generally, when I see a window misbehaving as yours are, I start looking for a missing call to pack() or validate() or invalidate() or whatever. Inserting those where they are needed generally makes my dialogs behave on all platforms, not just Windows. I don't know that this is the issue you're having, but it's where I start looking. -- Joi EllisSoftware Engineer Aravox Technologies [EMAIL PROTECTED], [EMAIL PROTECTED] No matter what we think of Linux versus FreeBSD, etc., the one thing I really like about Linux is that it has Microsoft worried.

Works fine for me (kernel 2.4.1, ibm jdk-1.3 build cx130-2815). Use the
