Eclipse – SimpleTagSupport was not found on the Java Build Path

Here is the development environment

  1. Eclipse 4.3 Kepler
  2. Java 1.7
  3. Spring 3.2, a MVC project using JSP view.

1. Problem

Recently, Eclipse IDE is prompting following error message on top of all of the .tag file.


The superclass "javax.servlet.jsp.tagext.SimpleTagSupport" 
   was not found on the Java Build Path.

See figure :

simpletagsupport-error

P.S The SimpleTagSupport class is unable to find in Open Type CTRL + SHIFT + T.

2. Solution

The SimpleTagSupport is belong to jsp-api.jar, which is always inside your runtime container, for example ${tomcat}\lib. Not really sure what is the real problem behind, to fix it, try setting a runtimes for your project.

See figure :

eclipse-facet-runtime

Right click on your project, select “Properties” -> “Project Facets” -> “Runtimes” , select your runtime container. Done, rebuild and refresh your project.
