From: Christopher Schultz [mailto:ch...@christopherschultz.net] Subject: Re: servlet access to static resources (pictures) We have defined some paths to static resources in the server.xml: Where did you define these Context elements? Looks like the OP was pretty specific about where... Is there a way to get the absolute paths of these folders in a servlet? Typically, one uses the request.getRealPath() method to find context-relative paths on a filesystem. However, these are static-content only webapps, there are no servlets in that context that can do a request.getRealPath(), which, as you noted, is a bad idea anyhow. Instead, try looking at the request.getResource family of methods: Again, these are static-only webapps, so there are no servlets or JSPs around to handle requests, other than Tomcat's DefaultServlet. If you just want to serve static resources, why not use the DefaultServlet, which already knows how to serve them? Clearly, the OP is already doing that. I suspect the actual problem is that there are other, real webapps that want to manipulate the static resources. Best I can think of is environment variables or Java system properties to allow specification of the locations on a JVM-wide basis. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: servlet access to static resources (pictures)
The context elements are defined in /%CATALINA_HOME%/conf/server.xml: Server ... Service ... Engine ... Host ... Context docBase= ... Context docBase= ... ... /Host /Engine /Service /Server There are two web applications that have access to these resources. The servlets main task is to calculate picture dimensions with java.awt.Toolkit. The request.getResource methods don't find these 'extern' paths.

So, you have one context with nothing but static content and another context with the servlets? Why not merge the two so there's no confusion? Aside from your original question: I'm not exactly sure what your requirements are, but it may be easier to use a simpler mechanism to determine picture dimensions than using java.awt.Toolkit to fully-load an image. Most image formats contain headers which indicate the dimensions of the image, while reading the full image data may require very heavy algorithms (I'm looking at you, discrete cosine transform). - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAktN+ukACgkQ9CaO5/Lv0PBwbACgnE0BwRmXRG9NacWtsdx+//dq Y8oAn0TeYUAOANhuKj1fe3c8TjrXPRW4 =u5tr -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Generally speaking, should your docBase point to the location containing your application ?

Yes, but these aren't real applications - they're simply sets of static resources handled by the DefaultServlet.
