I am creating/extending a simple TCDL tag following this link: http://www.tridiondeveloper.com/cleaning-and-extending-dynamic-linking
However, the IMPORT statement: import com.tridion.tcdl.TagRenderer;
is having error as not found. I have added all possible JAR files references to my Java project(in Eclipse). All the JAR files were taken from the lib
folder of my tridion website.
