Is there a way to speed up java? My applet (still in work in progress) www.dentella.it/java/morph.htm is quite big (900x600ca) and signed, but it takes 2 minutes to load (WinXP, FireFox 1.0, Celeron 1.3GHz, 256Mb RAM, Java 1.5)... Maybe can I give java more memory? Or are there other tricks? thanks! Back to top Andrew Thompson Guest Posted: Fri Nov 26, 2004 4:34 pm    Post subject: Re: Speed up applet execution?

The jar is only 5.7Kb. Quote: ..and signed, but it takes 2 minutes to load It took 8 seconds for my IE to report 'done', which, unless it is lying to me, is the time it took to contact the server, make a connection, download and parse the HTML, discover the applet, and download it as well. I refused the security certificate, and the applet appeared within 30 seconds. First, I need to be clear on what you mean by 'long time to load'. Put a System.out.println( "Date: " + new java.util.Date() ); ...at the start and end of the 'init()'. It might be that you are tryring to do too much in it.

Yes, I thought applet dimensions (900 x 600 pixels) could be the reason why it loads so slowly... Quote: I refused the security certificate, and the applet appeared within 30 seconds. why did you refuse my fantastic home-made certificate? A question about that... I've a working certificate (for my digital signature) given from a local authority... will it be accepted by Java or have I to buy one from Verisign? For my speed problem... I tried with IE and the applet is faster, maybe FireFox has some troubles. Thanks, you're replying to all my questions! :-) Back to top Luke Guest Posted: Fri Nov 26, 2004 4:57 pm    Post subject: Re: Speed up applet execution? Hello!

I use a 'self-signed' certificate for PhySci. <http://www.physci.org/install/download.jsp> <http://www.physci.org/install/security.jsp> It is just that I have to be cautious about what I am prepared to run on my extremely fragile machine. Quote: A question about that... I've a working certificate (for my digital signature) given from a local authority... will it be accepted by Java or have I to buy one from Verisign? Does not matter really. Either way the user will be asked if they intend to accept the certificate. If the 'local authority' has registered their certificate with VeriSign or Thawte etc., the message will be slightly less onerous. It will not have the part 'failed to verify the authenticity..' OTOH, there are others lurking that will tell you that a self-signed certificate is unsuitable for any 'real world' application/applet. Note that I have devoted a page on my site to explaining what the user will see, and why I do not have a 'verified' certificate. -- Andrew Thompson http://www.PhySci.org/codes/ Web & IT Help http://www.PhySci.org/ Open-source software suite http://www.1point1C.org/ Science & Technology http://www.LensEscapes.com/ Images that escape the mundane Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         AppletTalk.com Forum Index -> Java Help All times are GMT Page 1 of 1   Jump to: Select a forum Java Newsgroups----------------Java DiscussionsWeb-based java games comp.lang.java 3D Graphics API's for Java Java: Support and criticism Java System Announcements comp.lang.java.api JavaBeans Java and CORBA Java and Databases comp.lang.java.developer Java GUI Toolkits Java Help comp.lang.java.javascript JVM, native methods and hardware comp.lang.java.misc Java Language Programming Security and Java comp.lang.java.setup Java Software Tools comp.lang.java.tech ibm.software.java.linux  Non-English Java Newsgroups----------------Java Language (German)Language Java (Français)Java (Italian)  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
