jdeveloper 11g 11112 中出现错误

Question

我需要在 jdeveloper 11g 中编译我的项目的帮助。 以前，我的应用程序（jsp+servlet）可以在带有 oc4j 的 jdeveloper 10g 中顺利运行（在 WAR 文件中部署）。 但自从我迁移到 jdeveloper 11g 后，出现了几个这样的错误：

然后部署过程以不完整状态结束。 那我该怎么办？ 非常感谢。

Answer 1

看起来您的类路径上缺少 oracle.dmt.op.re.base.Enum ，因此：

java.lang.ClassNotFoundException: oracle.dmt.op.re.base.Enum$EnumType

添加 ${ORACLE_HOME}/dmt/oputil.jar 和/或类路径上的 ${ORACLE_HOME}/dmt/opreapi-batch.jar （不确定哪一个包含缺少的类，但无论如何它们经常一起使用）。

然后，重新运行 appc 作为第二个错误（helpdesk_project.CaptchaServiceSingleton 可能与第一个问题相关。

Answer 2

似乎找不到这个类：
java.lang.ClassNotFoundException: oracle.dmt.op.re.base.Enum$EnumType

还需要包含上面的类，您需要找到包含该类的 jar。
