In the current version of org.springframework.osgi.jstl.osgi only jstl is exported, whereas org.apache.taglibs.standart.* is required. If you'd like to run an app which requires jstl. it reminds you that also the taglibs are needed. So you have to create a bundle containing the standard.jar. The problem with that is that by creating that bundle you are getting a cyclic dependency as standart taglibs are requiring jstl. So at the moment org.springframework.osgi.jstl.osgi is not usable.
