activemq Kein geeigneter Log-Konstruktor

Question

Das treibt mich in den Wahnsinn. Ich versuche einfach activemq auf Mac OSX 10.5.7 zu laufen. Ich habe Java-Version 1.5.0_19 und activemq 5.2.0. Unten ist die Ausnahme, die ich bekommen, wenn bin / activemq läuft. Es scheint nicht in der Lage zu sein, log4j zu finden, die ungerade ist wenn man bedenkt es mit activemq kommt und ist auf jeden Fall in dem lib / optionals Verzeichnis. Das einzige, was ich denken kann, ist, dass ich einen Konflikt irgendwo, aber ich kann mir nicht vorstellen, wie dies möglich ist. Wenn jemand irgendwelche Tipps hat überhaupt bin ich ganz Ohr, produzierten fast keine Ergebnisse mit dem gleichen Fehler googeln, und die einzige Person, die den genauen Fehler hat keine Lösung hat.

Answer 1

Also, es war auf jeden Fall ein Konflikt mit einer anderen log4j JAR-Datei. Ich denke, es ist wahrscheinlich meine Eclipse-Plugin log4j, die widerstreit war. Wenn ich die log4j von activemq lib löschen / optional es funktioniert.

Answer 2

Das sieht aus wie die Ausnahme von einem NoClassDefFoundError für org.apache.log4j.Category verursacht wird. Sie sollten sicherstellen, dass das log4j Glas auf dem Classpath ist.

Edit: Gibt es eine Möglichkeit, dass Sie den Wert des ACTIVEMQ_CLASSPATH Variable inspizieren können? Wenn Sie dies durch ein Skript sind aufgerufen wird, der die Variable setzt, müssen Sie in das Skript graben, um sicherzustellen, dass es das Hinzufügen alle Verzeichnisse denken Sie an die Classpath ist.
