The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application

[Gibran Castillo]

I deployed donow62 Spring MVC app into Tomcat by placing donow62.xml file
in $CATALINA_HOME/conf/Catalina/localhost

The contents of donow62.xml are as follow:
<Context
docBase="/Users/gibranecastillo/Documents/workspace/CollegeLife/donow62/website"
reloadable="true"/>

They basically point to the website directory in the spring mvc project in
my eclipse workspace.

I looked at the Tomcat logs and it says donow62 deployed successfully. In
the "Tomcat Web Application Manager" I can see /donow62 listed there.

When I clicked on /donow62 it sends me to this URL
http://localhost:8080/donow62/ but instead of getting expected result and
the web page, I get HTTP Status 500 [see web browser log below]

My Spring MVC "donow62" app is using JSTL and it is in the classpath.
Using Eclipse on the donow62 project I created User Libraries that
reference all the dependencies for donow62. The SERVLET user library has
<> el-api.jar - /Library/Tomcat/apache-tomcat-8.0.12/lib/el-api.jar
<> jasper.jar - /Library/Tomcat/apache-tomcat-8.0.12/lib/jasper.jar
<> jasper-el.jar - /Library/Tomcat/apache-tomcat-8.0.12/lib/jasper-el.jar

<> javax-servlet.jsp.jstl-1.2.1.jar -
/Users/gibranecastillo/Documents/java/servlet/javax-servlet.jsp.jstl-1.2.1.jar


The exception is basically saying that the donow62 app is missing the JSTL
dependency, the jar, any suggestions on how fix this are welcome.

Is the JSTL JAR file in

If not, you aren't actually using it.

Although I don't do it myself, Eclipse is pretty good at deploying web
applications to Tomcat itself: you shouldn't have to even create your
own context.xml file and fill it with data.

If you want to do everything manually (believe me, I understand), then
you'll need to make sure that your Eclipse project successfully builds
to a WAR-like structure which contains, among other things, a WEB-INF/
directory and all of the things that should be in there (like
lib/*.jar). If you don't do that, then you won't really be deploying a
web application... you'll effectively be mapping a directory on the
disk into a URL space and getting no other benefits.

To fix the problem I put the .jar files in tomcat's lib directory and it
works.... best way to do this is like you said to put the *.jar files in
the WEB-INF/lib directory, build the project as WAR and deploy the war file
in Tomcat .... Where do I place the .war file in Tomcat? in the
'webapps' directory?

Yes, you would put the WAR file into Tomcat's webapps/ directory. If
you do that, you won't need the separate donow62.xml file.
