Re: How do you set up JMX remote for Tomcat 5.5.9?
Posted by teknokrat <te...@yahoo.com>.
you need to set
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=9998
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
check the last two as I can't remember the precise syntax. if youwant
password authentication read the doc

For simpler and more formal images like bar charts you can return
javascript and render image in browser.

Posted by Laurie Harper <la...@holoweb.net>.
Using a servlet seems reasonable. Whether or not you code will scale
adequately really depends on how generateMap() is implemented. If it can
process calls at the rate you anticipate needing you'll be fine. If it
can't you'll have to optimize it, introduce caching, use client-side
pre-fetching of image data á la Google Maps, whatever.

Yes,
a good idea would be not to hijack someone elses discussion thread and
start a new one instead. Then probably more people will read your question.
Regarding your original question: no idea

Re: generate image by servlet for large amount of requests
Posted by Ronald Klop <ro...@base.nl>.
We resize our images using Tomcat. The resized images are cached on the local disk with a nigthly cron, which removes unused files older than x days. Just try it and see what the load is. If the load is very high, buy more servers with a loadbalancer.
Ronald.

Re: generate image by servlet for large amount of requests
Posted by BH...@powersystems.rockwell.com.
maps.google.com uses AJAX to update their maps "on the fly" This allows
you to display on the portion of the image that is required on the page.
As you zoom in, out, of move around the map, they use a XML connection to
update the map.

generate image by servlet for large amount of requests
Posted by Tony Smith <qu...@yahoo.com>.
Let's think about maps.yahoo.com. I do not know how
they handle
millions of request and generate the map pictures
quickly. If I use a
servlet, in the post or get method I use:
BufferedImage mapImage =
myTookKit.generateMap(String address);
response.setContentType("image/png");
OutputStream os = response.getOutputStream();
ImageIO.write(buffer, "png", os);
os.close();
Is servlet a good choice? If I use servlet, is the
code above good
enough to handle hundreds of request? Is the choice of
BufferedImage a
good one? What special technique I need to implement
"myTookKit" to
make it faster? I am thinking about JNI.
Thanks,

Re: How do you set up JMX remote for Tomcat 5.5.9?
Posted by andy gordon <ef...@yahoo.com>.
Thank you for the info but I don't think it helped. Your insight is valued.
I set an environment variable called JAVA_OPTS to
-Dcom.sun.management.jmxremote.port=9998
and started tomcat using startup.bat. The cmd window opened and closed. Meaning tomcat didn't start. Suggestions?
I have not done anything else at this point with respect to enabling JMX remote.
Thank you
