JBoss 4.2 自動發現失敗 (NoClassDefFoundError)

我第一次嘗試使用 Hyperic。我有一個基本的伺服器和代理設置，並在 Redhat Linux 機器上工作。但是當自動發現器為 JBoss 4.2 執行時，我在這條消息的末尾得到了異常。

我jboss.installpath在agent.properties. 當我使用級別日誌記錄啟動代理時，DEBUG我看到配置的路徑中包含了各種 JBoss jar。但我無法自動發現 JBoss，我繼續得到相同的異常。任何有關如何解決此問題的想法將不勝感激…

將 JBoss 中的 jbossall-client.jar 放在 Hyperic Agent 的類路徑中，即（在 Hyperice Agent 的相關庫中）。

還要檢查..

問題可能是由於 Hyperic-Agent 無法擷取 JBoss-Server，因為使用了反斜杠而不是普通斜杠。

jboss.installpath=e:\jboss-4.2.1.GA -> 不行

jboss.installpath=e:/jboss-4.2.1.GA -> OK
