Plugin bug??
Hi, I send this e-mail, because I'm not sure if it's a Java Plugin1.2.2 bug or if I'm doing something wrong. I'm working in a system which has a Java Interface accesed via HTTPS. The Java Plugin does not support https itself. So when I try to go into the web page, the Plugin and the Navigator crash together. I downloaded the jsse1.0.1 extension which is supposed to support https. Following the README instructions I copied the jsse.jar, jcert.jar, and jnet.jar in /.netscape/java/lib/ext directory. Then I restarted the javaPlugin and added the -Djava.protocol.handler.pkgs=com.sun.net.ssl.internal.www.protocol to the java params. So now my /.java/properties file looks like: # Propiedades módulo Java(TM) # DO NOT EDIT THIS FILE. It is machine generated. # Use the Activator Control Panel to edit properties. # #Wed Jul 12 08:20:20 GMT+02:00 2000 javaplugin.debug.mode=false javaplugin.proxy.forallprotocols=false javaplugin.version=1.1 javaplugin.jre.params=-Djava.protocol.handler.pkgs\=com.sun.net.ssl.internal.www.protocol javaplugin.jar.cache.size=100 javaplugin.jre.path=/home/jaime/.netscape/java javaplugin.console=true javaplugin.enabled=true javaplugin.proxy.usebrowsersettings=false javaplugin.proxy.settings=https\=madeleine\:8002 appletviewer.security.mode=host But when I try to acces the https page both, the Plugin and the Navigator crash!! The plugin_stack.trace contains the following text: java.net.MalformedURLException: unknown protocol: https at sun.plugin.navig.motif.Plugin.doit(Plugin.java, Compiled Code) at sun.plugin.navig.motif.Plugin.start(Plugin.java, Compiled Code) Could it be a bug or am I doing something wrong?? If anybodie needs any additional information about it, just let me know.(But don't expect a wide knowledge about java, I'm steel a newbie!!) begin:vcard n:Vallori Amorós;Jaime tel;work:91 744 43 10 x-mozilla-html:TRUE org:Grupo Apex S.A. adr:;; version:2.1 email;internet:[EMAIL PROTECTED] x-mozilla-cpt:;-27872 fn:Jaime Vallori Amorós end:vcard

Each thread has a wake method, which sets the desired computation and send a notify to unblock the semaphor. The dummy method contains only a return, nothing more. > What I think really happened is that your timer thread T is doing all > the work, giving you the impression that the program is making > progress, while all other threads are still blocked and not waken. but that's not what the debugger reports when using the timer, and hitting threads, at any time is see different threads alive, without the timer, all threads are asleep after a while. so this seems very strange -- ciao bboett == [EMAIL PROTECTED] http://inforezo.u-strasbg.fr/~bboett http://erm1.u-strasbg.fr/~bboett === the total amount of intelligence on earth is constant. human population is growing -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Printing and fonts revisited
Hello all. This is my first post to this list. I'm working with the Graphics2D class of JavaSoft Java 1.2 to print a very small file. When I examine the PostScript code, I don't see anything like "(hello) show" in the code. Instead, I see lots of PostScript operators drawing the outline of each character. In desperation, I extended Graphics2D and implemented drawString() myself. (Never extended an abstract class before. That was an experience! Still have a lot of stubs in places.) I now get reasonable results and the small PostScript file that I want. I delayed doing this for the longest time possible because it really felt unnecessary (certainly for English). I finally bit the bullet because I'm really doing this for Asian CID fonts loaded in a PostScript Level 3 printer. But I'd still like to know if my subclassing Graphics2D was the wrong approach. (Someone pointed me at PrintStream in awt.motif in the Solaris version, but I couldn't find it documented.) System specifics: Java version "1.2.2" Classic VM (build 1.2.2-L, green threads, nojit) Oh yeah... The previous post to this list which comes closest to describing what I'm seeing was from Klas Nordberg <[EMAIL PROTECTED]>, on 09 Feb 2000, subject "Printing and fonts". He was using RC4 of Blackdown's JDK. However, I don't see any response to his questions. --Rick Kwan, Lightsaber Computing [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
