Re: Jakarta Taglibs Installation
Excellent idea. I should have a look at the document type definition for the web.xml file to find out where exactly I should place the context-param element and its contents, and then perhaps also validate the resulting XML file with an XML validator with the DTD also supplied as input. The DTD does not come with tomcat or taglibs but... $ find /usr/local/jakarta-tomcat-4.1.24 -name '*dtd' $ find /usr/local/jakarta-taglibs -name '*dtd' $ The file /usr/local/jakarta-tomcat-4.1.24/webapps/ROOT/WEB-INF/web.xml reveals its location: http://java.sun.com/dtd/web-app_2_3.dtd OK, I validated the page versus the DTD using the XML validator at http://validator.w3.org/ and found the page to be valid XML, that is the XML file is well-formed and validates versus the DTD. I also checked it at the following site: http://www.stg.brown.edu/cgi-bin/xmlvalid/xmlvalid.pl and obtained the same results (except for the following warning which I suppose is nothing to worry about): line 2, web.xml: warning (562): can't resolve Public ID: -//Sun Microsystems, Inc.//DTD Web Application 2.2//EN Both validators nevertheless downloaded the DTD from the contents of the second string specified in the document type declaration and did find the document to conform to the DTD, so that was not the problem. The error message reported is clearly wrong. Regards, Neil On Sat, 5 Jul 2003, N.

Jakarta Taglibs Installation
Hello, I have installed Jakarta Tomcat 4.1.24 and Jakarta Taglibs 1.0.3, both of which support the JSP specification. I found the README file /usr/local/jakarta-taglibs/standard-1.0.3/README to be close to useless: it seems to me that copying the files standard-doc.war and standard-examples.war to the WEB-INF/classes is almost irrelevant: what do I do once I copy them? How do I test them? With a JavaServer page with the following directive: %@ taglib prefix=c uri=http://java.sun.com/jstl/core; % I was getting the following error: uri (http://java.sun.com/jstl/core) cannot be resolved and then also the error: org.apache.jasper.JasperException: File /WEB-INF/c.tld not found Hence I fixed it with: $ cp /usr/local/jakarta-taglibs/standard-1.0.3/tld/c.tld \ ~/public_html/WEB-INF This is undocumented though. Is it what I'm supposed to do?

Indeed, under JSP 1.2, the taglib element is unnecessary. As for duplicating the JAR files for each application, it's simply the cost -- and an exceedingly minor one in any reasonable environment -- of appropriate architecture. The advantages of including JAR files with an individual application include - a clear statement of the dependencies of the application and the ability to easily WAR it up and redeploy elsewhere - automatic detection of the JAR files' taglibs - isolation of 'static' data from other applications because a classloader specific to the web application loads the JAR files' classes; this can be important for security and for troubleshooting Shawn - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Jakarta Taglibs Installation
Thanks for your info. I never do that before.Maybe I need to have a detailed look at the sections you mentions if I have time later.After a glimpse of these lines,a question pops up my mind: If it is *mandatory*,why the web-app.dtd still specifiy an optional taglib element?Just for backward compatibility? Anyway,thanks for clarification. --- Shawn Bayern [EMAIL PROTECTED] On Mon, 30 Jun 2003, [gb2312] guo yingshou wrote: Are you sure it works on all j2ee complaint servlet engine? The behavior is mandated by sections 7.2.1 and 7.3.1 of the JSP 1.2 specification, so all compliant containers support it; if a product claiming compliance doesn't support it, then it's a bug.
