Re: Image tag lib doesn't work on Windows 2003 server?
Can you be more specific about what you mean by doesn't work? Do you get an exception? Have you tried running the JVM with -Djava.awt.headless=true? Are you using the same JDK and app server versions on both XP and Server 2003?

Anyone can give me some advice? Thanx.

Re: Image tag lib doesn't work on Windows 2003 server?
If you can't change the env so that the app can create and write to that directory, I think you can try this (some of the info can be found in the docs: http://jakarta.apache.org/taglibs/sandbox/doc/image-doc/index.html). Add the following to web.xml: context-param param-nameImageServletMapping/param-name param-value/gen-image/param-value /context-param servlet servlet-nameImageServlet/servlet-name servlet-classorg.apache.taglibs.image.ImageServlet/servlet-class /servlet servlet-mapping servlet-nameImageServlet/servlet-name url-pattern/gen-image/*/url-pattern /servlet-mapping Then remove the dir attribute from the image tags. For example, if you had this: img:image src=/images/splash.jpg dir=generated name=splash-new.jpg attributes=alt='A sample image' refresh=false quality=0.8 /img:image Use this instead: img:image src=/images/splash.jpg name=splash-new.jpg attributes=alt='A sample image' refresh=false quality=0.8 /img:image This should store images in a temp dir instead of the one specified by dir. Hopefully, the app will be able to write to that dir... On 9/24/07, zhou peng [EMAIL PROTECTED] wrote: Thanx for Kirs' advice.

Re: Image tag lib doesn't work on Windows 2003 server?
Thanks a lot, Kirs. I have tried your method, it still can't show image when use wan connected. I have no idea about how to change the env so that the app can create and write to generated or temp-dir, can you give me an examples for windows 2003 server. I have checked our app, it can create chart png at tomcat\temp with jfreechart, maybe we could change the env so that app can use it or app\generated dir. I think both your method or our app could show correctly because our server disable some user account or rights, so we can change some env for the dir such as generated or app, and can still safe? More help, please!
