Hi,

I'm using JSTL 1.0 since I have to use JSP 1.2 and cannot upgrade to JSP 2.0
I choosed the reference implementation that comes with the Java Web Services Developer Pack from Sun.

I've seen the Apache Jakarta group have also done an implementation of JSTL 1.0 specification. (a project called Taglibs).

�Is this implementation better than the one from Sun?. I've read that with this implementation you can use a class called ExpressionEvaluatorManager, which help evaluating EL expressions for custom tags attributes. That is really helpful if you cannot use JSP 2.0

Will it be much trouble to change to the Jakarta implementation?. I mean, will I have to edit the jsps and the taglibs?

Thanks in advance
Jorge

Since both implementations are based upon a standard, it should be fairly easy to switch out. Replace the Sun jars with the Jakarta jars and (unless you have hard-coded references to files somewhere rather than letting the container do auto-discovery, or did not use the standard URIs to refer to the tlds) you should be good to go.

I've only used the Jakarta implementation (and now I'm using 1.1 rather than 1.0) and have had no difficulties except with the 'x' class of tags.
