Paginierung in Struts 1.2.9 in Java EE

Question

Ich versuchte Seitenstriche in Objectsweb Lomboz Eclipse Version 3.3. Aber ich habe einen Fehler "keine Klasse gefunden".

Die Fehler sind
Ausnahme

Ich weiß nicht, was mit dem Code falsch ist. Ich habe es von viralpatel.net kopiert. Ich habe das Gefühl, dass dieser Code nur für Struts 2 gilt. Wenn Sie also ein Paginierungsprogramm für Struts 1.2.9 haben, geben Sie dies bitte in einer Antwort an.

Answer 1

Überprüfen Sie bitte die Grundursache des Fehlers. Darin heißt es eindeutig:

java.lang.NoClassDefFoundError: org/apache/commons/lang/UnhandledException 

Was bedeutet, dass die Klasse UnhandledException (von org.apache.commons.lang Paket) nicht (überall in Ihrem Classpath) gefunden.

Laden Sie die neueste Apache Commons-Bibliothek von Apache Commons herunter und legen Sie das Glas in das Verzeichnis Ihres Projekts WEB-INF/lib oder deklarieren Sie den Pfad im Klassenpfad.
