Scheint, Sie haben unvollständige jar-Bibliotheken bereitgestellt, die in Ihrem Projekt. Versuchen Sie den download benötigten jars aus dem maven-repository oder schauen Sie in der struts-Distribution lib Ordner.
```
commons-lang3-3.1.jar
```
fehlt.

Sehen so erstellen Sie ein maven-Projekt.
- Ich habe eine view-Seite, die verwendet <s:property> - tag und es funktioniert OK
- Danke. Das Problem ist jetzt behoben. Ich hatte, um zwei commons-lang-Gläser - commons-lang-2.4.jar und commons-lang3-3.1.jar. Als commons-lang3-3.1.jar allein war Sie nicht lassen Sie die Anwendung bereitstellen.
