java - .class 文件中的版本号错误。在 Jdev 10.1.3.4.0 中嵌入的 oc4j

我正在将一个项目从在 tomcat 上的 Netbeans 中运行转换为在嵌入式 tomcat 上的 jdeveloper 中运行。但我遇到了这个错误:

oracle.classloader.util.AnnotatedClassFormatError: Bad version number in .class file

我读到这与版本有关，但我已将所有内部 jar 编译为 1.5，并确保我的项目也以 1.5 为目标

有关如何解决或如何“升级”嵌入式 OC4j 的任何建议

完整的堆栈跟踪:

一些堆栈跟踪的翻译:

 Ugyldig klasse: dk.myproject.bII.login.actions.LoginActionForm
             Indlæser: current-workspace-app.web.DefaultProject:0.0.0
        Kodekilde: /C:/workspace/myproject/test/Return/libs/BUtilities.jar
      Konfiguration: <classpath> in C:\workspace\myproject\test\Return\Client\public_html

翻译成:

Invalid class : ....
loading: ....
sourcecode : ...
configuration : ....

更新:检查所有 jar 文件，最高版本均为 49 (java 1.5)。有人知道如何检查嵌入式oc4j可以运行的版本吗？

最佳答案

通常，当您的项目使用比 oc4j 更高版本的 JAVA 时，就会出现该错误。您必须检查 oc4j 的 JRE 版本，并且您已经使用该版本构建了项目。

我不确定 Netbeans，但如果您使用 eclipse，那么您必须在项目中进行两项更改:-1.转到项目属性并选择Java编译器，根据oc4j上的版本更改版本

  • 转到项目属性并选择项目构面，并在此处更改 JAVA 版本

    • 希望这有帮助

    关于java - .class 文件中的版本号错误。在 Jdev 10.1.3.4.0 中嵌入的 oc4j，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23777411/
