I started practising taglibraries. They are working fine. But my doubt is in the book they has used tomcat 3.1 as container and i am using tomcat 4.1 as container in my system. if i put the code they has given and tried to execute the program it is giving tlibversion must be specified. I checked the jsp examples in the container I found it is tlib-version. is any tag with name "info" available from tomcat 4.1 and above.
