带有JSF 2的Websphere 7 [英] Websphere 7 with JSF 2
问题描述
对于在Websphere 7.0.0.13下运行的应用程序，我需要使用JSF 2，我已经遵循了这一点:
I need to use JSF 2 for an application running under Websphere 7.0.0.13, I have followed this:
http://www.manorrock.com/online/wiki/app/page/edit.html
***它说:
Even though Websphere 7 does not formally support JSF 2.0 you can get it to work in a degraded mode. Follow the steps below to get it to work on your version of Websphere 7.
Upgrade to at least version 7.0.0.13
Ship the Mojarra JAR files in your WEB-INF/lib directory
Set the WAR classloader to PARENT_LAST
Set the EAR classloader to PARENT_LAST and APPLICATION
Note the degraded mode means you are NOT going to be able to use @Resource or any JPA annotations. If you think you need support for it contact your IBM representative.
Note it will process @PostConstruct and @PreDestroy.***
我这样做了，但是在日志中出现了这个错误:
I did this, but I getting this error, in the log:

错误出现在我的页面上
Error 404: javax.servlet.UnavailableException: SRVE0201E: Servlet [javax.faces.webapp.FacesServlet]: not a servlet class
这是我的web.xml
This is my web.xml
<?xml version="1.0" encoding="UTF-8"?>

我通过:

如果我输入:
..../testJSF2/index.jsp
在页面中获取它:

感谢您的帮助.
推荐答案
对于WebSphere 7，我关注了另一篇文章:
For WebSphere 7, I've followed another article:
http://wasbehindtheglass.blogspot. co.uk/2011/11/myfaces-20-and-websphere-application.html
我已经在WebSphere上使用以下jar创建了共享库(名称并不重要，只包含内容):
I've created shared library on WebSphere (name is not important, only content) with following jars:
manifest.jar
myfaces-api-2.0.7.jar
myfaces-impl-2.0.7.jar
commons-logging-1.1.1.jar
commons-digester-1.8.jar
commons-collections-3.2.jar
commons-codec-1.3.jar
commons-beanutils-1.8.3.jar
\ IBM \ SDP \ runtimes \ base_v7 \ optionalLibraries \ IBM \ JSFProviders \ WebSphere-MyFaces20-annotation-provider.jar
manifest.jar
myfaces-api-2.0.7.jar
myfaces-impl-2.0.7.jar
commons-logging-1.1.1.jar
commons-digester-1.8.jar
commons-collections-3.2.jar
commons-codec-1.3.jar
commons-beanutils-1.8.3.jar
\IBM\SDP\runtimes\base_v7\optionalLibraries\IBM\JSFProviders\WebSphere-MyFaces20-annotation-provider.jar
您需要给出绝对路径. WebSphere-MyFaces20-annotation-provider.jar应该在您的WebSphere安装中. manifest.jar是仅包含以下META-INF/MANIFEST.MF的jar:
You need to give absolute paths. WebSphere-MyFaces20-annotation-provider.jar should be in your WebSphere installation. manifest.jar is the jar containing only following META-INF/MANIFEST.MF:
Manifest-Version: 1.0
Extension-Name: org/apache/myfaces
Specification-Title: MyFaces 2.0.7 shared lib
Specification-Version: 1.0
Specification-Vendor: apache.org
Implementation-Version: 1.0
最后要做的是修改pom.xml以创建引用共享库的清单条目:
Final thing to be done is to modify your pom.xml to create the manifest entries referring the shared library:
<manifestEntries>
<Extension-List>myfaces</Extension-List>
<myfaces-Extension-Name>org/apache/myfaces</myfaces-Extension-Name>
<myfaces-Specification-Version>1.0</myfaces-Specification-Version>
</manifestEntries>
部署后，如果正确配置了共享库和清单，则会自动创建绑定.
After the deploy, if both shared library and manifest are configured correctly, the binding is automatically created.
