我想創建一個使用Java，澤西島和camunda lib構建bpmn項目的Web REST服務。java.lang.NoClassDefFoundError：org/camunda/bpm/model/bpmn/instance/FlowNode
我的項目通過HTML表單頁面從用戶處獲取兩個文件，並且應該在特定的目標上從它們創建兩個aut文件。
我在服務器上傳文件時出現了這個錯誤。

該進程創建0字節的.aut文件。
爲什麼我得到這個錯誤？我在我的項目中添加包含flownode類的庫。爲什麼它不工作？
編輯：我使用Tomcat作爲服務器在Eclipse IDE上運行它。我已經在我的java構建路徑庫的WEB-INF文件夾中添加了所有的lib。
您使用的是maven嗎？你如何打包你的代碼？這是罐子，戰爭還是耳朵？如果是戰爭，WEB-INF/lib文件夾中是否存在這些庫？ – phoenixSid
是的，我使用maven項目，eclipse和tomcat。是的，這些lib都在web-inf文件夾中！ – Dario
你是在eclipse中運行還是在tomcat中單獨部署戰爭？ 您是否嘗試刪除爆炸戰爭並再次啓動服務器？ – phoenixSid
