Re: Including jsp files that exist outside of the web application
I cannot understand your situation. If you use the include directive, then the JAVA Servlet file will include the info in the JSP file which is included. If you use the include element, then the included JSP file will have its own separate JAVA Servlet file. Accordingly, the include element requires a JAVA Servlet file to be loaded with a class loader. So, you must be using JSP files that are edited outside the web application and then inserted into the web application, where they are then compiled and included via reference by other Servlets. Right? I am not sure what the problem is with overwriting. I am also not sure what you mean by them existing outside the web application. If by being edited outside and included in a web application is what you mean by existing outside, what is the problem? Sorry to be dark, but this is a mysterious discussion to me. You guys clearly understand what you are talking about. I don't. Consider this a subquestion in an attempt to be helpful. ;-) Jack On Mon, 27 Dec 2004 12:22:50 -0800 (PST), [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: Hello, We have a web application that is overwritten each time we push a new version of the code into production.

Re: Including jsp files that exist outside of the web application
What if you don't include the JSP file but include the related JAVA file and use CLASSPATH? Will that work? You cannot, of course, make this dynamic, since you have class loader issues. The biggest issue is the class loader issue. You might create a set of interfaces and implemenations outside your web application that allow dynamic reloading. I don't see, however, why your edited files are not just popped into your web application without issues?

You guys clearly understand what you are talking about. I don't. Consider this a subquestion in an attempt to be helpful. ;-) Hi Jack, The basic idea is, we have jsp's that must be edited on the fly, through a web page. Those edits must survive updates of the application itself. So, if you think of the edited jsp's as being headers or footers that are included in other jsp files, we want to save these headers and footers outside of the tomcat/webapps/ROOT directory, because this will get deleted when we deploy a new ROOT.war file. So, we were hoping on saving them in something like /var/jsp/footer.jsp and /var/jsp/header.jsp so that when /usr/local/tomcat/webapps/ROOT gets deleted and then redeployed with a new version of the application, we can continue using the old footer.jsp and header.jsp files. And unfortunately, these special files do need jsp code, and must be more than just html.

Re: Including jsp files that exist outside of the web application
You know, I'm not sure how often this comes up for people, but it might make a good custom tag... I can imagine simply a version of jsp:include that allows for absolute paths. Sure, it'll tie you to an OS to some degree (i.e., change paths from Windows forms to Unix forms), but that might be something people can live with. -- Frank W.

Hello, Thanks for your response. I agree wholeheartedly, and would like to be able to have this code live outside of that, since it's goign to change throughout the lifetime of the webapp (and must maintain its changes before and after). However, the tricky part here, is that the code needs to be compiled dynamically as part of the jsp. Maybe that's the real question. Is there a way to include jsp code outside of the webapp that will be compiled runtime? Thanks, -Raiden - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Including jsp files that exist outside of the web application
Could you do something like the following? You'll be essentially doing
something like curl to get the output from the other app and simply writing
it out in your app. This has been tested but should help you get the idea. I
did something similar to send a POST request to an external site and then
just displayed the output in my app.
%
URL url = new URL(http://path_to_other_app/other_page.jsp;);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setUseCaches(false);
conn.setRequestMethod(GET);
// Get the response
BufferedReader rd = new BufferedReader(new
InputStreamReader(conn.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
out.println(line);
}
