我按照此处example找到的基本教程,似乎无法解决以下错误:
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几次我可以生成略有不同的堆栈跟踪,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

我已经筋疲力尽了几个小时在网上搜索并构建了没有运气的新项目。我知道StackOverflowError是由错误的递归调用和无限循环产生的,但我不能在这里看到这种情况。
我目前的开发堆栈是eclipse juno,m2e-wtp,weblogic 12c,Java EE 6使用JSF 2.1
我希望它像我的pom.xml中缺少的依赖项或weblogic插件一样简单。任何帮助都会让我很感激。
更新1:如果我使用eclipse导出war文件(右键单击项目 - &gt;导出 - &gt; WAR文件),然后通过weblogic admin顾问手动部署它,应用程序按预期工作。更具体地说,eclipse的版本是来自oracle的版本(oepe-12.1.1.2.1-juno-distro-win32-x86_64.zip)。

OP写道:解决了问题!在pom.xml中添加JSF 2.1后,在项目方面检查了JSF 2.1复选框,但是它没有将faces-config.xml添加到项目中。我简单地在webapp下创建了一个名为faces-config.xml的新xml文件 - &gt; WEB-INF文件夹并添加了以下xml:
<?xml version='1.0' encoding='UTF-8'?>
<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-facesconfig_2_1.xsd" version="2.1">
<application></application>
</faces-config>
我希望这有助于其他人!
