Default JSP2 EL/JSTL being ignored

After reading 'Beginning Java Server Pages'
I recently upgraded from j2sdk 1.4 to j2se 1.5.0_06
and Tomcat from 4.0 to 5.5.15
I am still using j2sdkee 1.3

I have built a system to the MVC architecture and now want to write all new JSP using EL/JSTL.

As a test I wrote the following jsp2Test.jsp and it appears the core tags are ignored. Then I added ...

    <jsp-config>
      <jsp-property-group>
        <url-pattern>*.jsp</url-pattern>
        <el-enabled>true</el-enabled>
        <scripting-enabled>true</scripting-enabled>
      </jsp-property-group>
    </jsp-config>

... to my deployment descriptor, which resulted in no change.

In this jsp2Test.jsp file only the last two lines(+) of template data are output as follows without any EL translation, with or without a request param:

buyer = ${buyer}
param.buyer is ... [${param.buyer}]

I imagine JSP is bundled with j2ee and not j2se.
Do I need to upgrade my j2ee ????
or am I missing something else.
Would appreciate some help here.
