java.lang.StackOverflowError在Weblogic 12c上运行JSF 2示例 [英] java.lang.StackOverflowError Running JSF 2 example on Weblogic 12c
问题描述
我遵循了示例并且似乎无法通过以下错误:
I followed the very basic tutorial found here example and cannot seem to get past the following error:
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)
几次按shift + F5组合键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

我已经花了几个小时在网络上搜索并构建新项目，但是没有运气.我知道StackOverflowError是由错误的递归调用和无限循环产生的，但是在这里我看不到这种情况.
I have exhausted several hours searching the web and constructing new projects with no luck. I understand that the StackOverflowError is produced from bad recursion calls and infinite loops, however I can't see this as the case here.
我当前的开发堆栈是使用JSF 2.1的eclipse juno，m2e-wtp，weblogic 12c，Java EE 6
My current dev stack is eclipse juno, m2e-wtp, weblogic 12c, Java EE 6 using JSF 2.1
我希望这很简单，例如pom.xml中缺少依赖项或weblogic插件.任何帮助我都将不胜感激.
I am hoping it is something simple like a missing dependency or weblogic plugin in my pom.xml. Any help would me MUCH appreciated.
更新1:如果我使用eclipse导出war文件(右键单击项目-> Export-> WAR文件)，然后通过weblogic管理员建议手动部署该应用程序，则该应用程序将按预期工作.更具体地说，eclipse的版本是oracle的版本(oepe-12.1.1.2.1-juno-distro-win32-x86_64.zip).
UPDATE 1: If I export the war file using eclipse (Right click the project -> Export -> WAR file) then manually deploy it via the weblogic admin counsel the app works as expected. More specifically the version of eclipse is the one from oracle (oepe-12.1.1.2.1-juno-distro-win32-x86_64.zip).
推荐答案
(Answered in a question edit. Converted to a community wiki answer. See Question with no answers, but issue solved in the comments (or extended in chat) )
OP写道:
解决了问题！在pom.xml中添加JSF 2.1之后，在项目构面中选中了JSF 2.1复选框，但是未将faces-config.xml添加到项目中.我简单地在webapp-> WEB-INF文件夹下创建了一个名为faces-config.xml的新xml文件，并添加了以下xml:
Solved the problem! After adding JSF 2.1 in the pom.xml the JSF 2.1 checkbox was checked in project facets, however it did not add the faces-config.xml to the project. I simple created a new xml file named faces-config.xml under the webapp --> WEB-INF folder and added the following 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>
我希望这对其他人有帮助！
