As David suggests, java.io.tmpdir is probably a bit safer than /tmp, since you have some control over that and it can be isolated from other programs running on the same box. The real problem is how to retrieve the images once stored. Tomcat normally uses its built-in DefaultServlet to deliver static content, but that only works with files stored within a given webapp (and you should never write into a webapp's deployment directory). You have a couple of options: 1) Create a dummy webapp whose sole purpose is to provide a location for the dynamically generated images. Create some directory outside of Tomcat's file structure to hold the images, and place a <Context> element in conf/Catalina/[host]/[dummyAppName].xml with a docBase attribute (and nothing else) that points to that directory. The <img> tags should refer to [dummyAppName] as the URL for retrieving the images. - or - 2) Create a subclass of DefaultServlet that knows where you put the images, and direct image references to it via the appropriate servlet-mapping in your WEB-INF/web.xml file. Not sure which methods of the DefaultServlet you'll have to override. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
