String.format()error (works in a class file , not in jsp)

So I suppose your answer to the question "Are you sure you're using Java 5" is "No I am not sure", because you didn't answer that. Whatever environment your JSP is running in, it isn't using Java 5.

I get excactly the same problem.

If compile the the JSP in Netbeans it works fine, however when Tomcat attempts to compile it into a servlet at runtime, I get the same error as described.

This is the line in JSP that fails:

<code>Some more text <%= String.format("%s","Bizarre") %> </code>

However this one works OK:

<code>Some more text <%= "Bizarre".substring(3) %> </code>

Its almost as if Tomcat is compiling under JDK 1.4.2 or something but I don't have any other JDK or JRE installed; only 1.5.

I suspect it may be a Tomcat setting that's causing a 1.4 code compliance.

In Netbeans, if I go to the project properties -> Sources, at the bottom is the "Source Level" drop down list. If I change this to 1.4 and clean and build the whole project I get the same error when the jsp (or any class with this construct) is compiled by NetBeans.

Note: I am using the Netbeans 5.0 and Tomcat and 5.5.9 co-bundle which I downloded from the Sun website.

Can anyone help?

Heres the splurge from the browser output:

org.apache.jasper.JasperException: Unable to compile class for JSP
