step-by-step tutorial

[ehillmuth]

I'm working my way through Part 2 of "Developing a Spring Framework MVC application step-by-step". So far I have only had one show stopper. After completing Step 14, building and deploying I get this error:

2004-08-12 13:01:45 StandardWrapperValve[jsp]: Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException: /index.jsp(1,1) The absolute uri: http://java.sun.com/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application
at org.apache.jasper.compiler.DefaultErrorHandler.jsp Error(DefaultErrorHandler.java:39)

(Full stack trace and the end of this message)

I can see that jstl.jar made it to Tomcat because its sitting in ~\webapps\springapp\WEB-INF\lib\

I am using spring-framework-1.1-rc1-with-dependencies and Tomcat 5.0.27. Any pointers would be appreciated.

You're likely missing standard.jar in WEB-INF/lib; it's available with the spring with dependencies under lib/jakarta-taglibs/standard.jar.

[ehillmuth]

Indeed! That did the trick.

Many thanks

Hello
I'm exploring the framework by going through the step-by-step tutorial.

I have completed step 14 (Improve the view and the controller), but it doesn't work as it should.

I'm positive that i have the right source (used cut'n'paste), but when i try to run the application i get the output

Greetings, it is now ${now} instead of the time and date which it should display.

I don't want to continue the tutorial before i've found the sollution for this.
Can someone give me a hint what may be wrong?

Regards
Per

For me, this happened when I had the wrong URI for the tag libraries in the "include.jsp" file. I was using:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>, but I should have been using:
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>

I'm using v2.0.1 of the Spring Framework with dependencies.

This may not be the place, but I've been looking around and I can't seem to figure out where to ask. In my controller, I return a ModelAndView and it has a class in the model that I've made with very simple attributes and methods. Normally in a jsp, assuming that I've named my model as "model", I can do ${model.thisclass.id} and that will get me the id from the class. This is nice, but is it possible to use a method from the class in the jsp? I would like to be able to do something like ${model.thisclass.getId()} Is this possible?
