我按照这里找到的非常基本的教程示例,似乎无法克服以下错误:
Error 500--Internal Server Error
java.lang.StackOverflowError
at weblogic.servlet.internal.ServletResponseImpl.addHeader(ServletResponseImpl.java:567)
at javax.servlet.http.HttpServletResponseWrapper.addHeader(HttpServletResponseWrapper.java:200)
at javax.servlet.http.HttpServletResponseWrapper.addHeader(HttpServletResponseWrapper.java:200)
at javax.servlet.http.HttpServletResponseWrapper.addHeader(HttpServletResponseWrapper.java:200)
at javax.servlet.http.HttpServletResponseWrapper.addHeader(HttpServletResponseWrapper.java:200)
按 shift + F5 几次,我可以生成稍微不同的堆栈跟踪,如下所示:
Error 500--Internal Server Error
java.lang.StackOverflowError
at com.sun.faces.application.ViewHandlerResponseWrapper.setStatus(ViewHandlerResponseWrapper.java:88)
at javax.servlet.http.HttpServletResponseWrapper.setStatus(HttpServletResponseWrapper.java:224)
at com.sun.faces.application.ViewHandlerResponseWrapper.setStatus(ViewHandlerResponseWrapper.java:88)
at javax.servlet.http.HttpServletResponseWrapper.setStatus(HttpServletResponseWrapper.java:224)
这是我的 web.xml

我已经用尽了几个小时在网上搜索和构建新项目,但没有运气。我知道 StackOverflowError 是由错误的递归调用和无限循环产生的,但是我在这里看不到这种情况。
我当前的开发堆栈是使用 JSF 2.1 的 eclipse juno、m2e-wtp、weblogic 12c、Java EE 6
我希望这很简单,比如我的 pom.xml 中缺少依赖项或 weblogic 插件。任何帮助我都会非常感激。
更新 1:如果我使用 eclipse 导出 war 文件(右键单击项目 -> 导出 -> WAR 文件)然后通过 weblogic 管理员顾问手动部署它,该应用程序按预期工作。更具体地说,eclipse 的版本来自 oracle (oepe-12.1.1.2.1-juno-distro-win32-x86_64.zip)。
