Maarten,

This should have worked, but it didn't.

    <servlet>
        <servlet-name>jsp</servlet-name>
        <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
        <init-param>
            <param-name>fork</param-name>
            <param-value>false</param-value>
        </init-param>
        <init-param>
            <param-name>xpoweredBy</param-name>
            <param-value>false</param-value>
        </init-param>
        <init-param>
            <param-name>compilerSourceVM</param-name>
            <param-value>1.5</param-value>
        </init-param>
        <init-param>
            <param-name>compilerTargetVM</param-name>
            <param-value>1.5</param-value>
        </init-param>
        <load-on-startup>3</load-on-startup>
    </servlet>

This is what $CATALINA_HOME/conf/web.xml must contain to enable this feature.

I tried various combinations of ant.jar, jasper-compiler-jdt.jar and classes.jar. If I replace jasper-compiler-jdt.jar with ant.jar, I no longer get compile errors for JDK 1.5 features. This is what I get instead:

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

Generated servlet error:
error: error reading /System/Library/Java/Extensions/libJ3D.jnilib; java.util.zip.ZipException: error in opening zip file
1 error

        org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:84)
        org.apache.jasper.compiler.ErrorDispatcher.javacError(ErrorDispatcher.java:328)
        org.apache.jasper.compiler.AntCompiler.generateClass(AntCompiler.java:246)
        org.apache.jasper.compiler.Compiler.compile(Compiler.java:288)
        org.apache.jasper.compiler.Compiler.compile(Compiler.java:267)
        org.apache.jasper.compiler.Compiler.compile(Compiler.java:255)
        org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:556)
        org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:296)
        org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295)
        org.apache.jasper.servlet.JspServlet.service(JspServlet.java:245)
        javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

This is definitely OS X-specific.   It doesn't matter whether or not I include classes.jar.

Any ideas?

Thanks,
Luke
