Jboss 启动问题

1.web.xml元素先后顺序

  我的Jboss是5.1GA, Error Message:

AXException: The content of element type "web-app" must match "(icon?,display-na
me?,description?,distributable?,context-param*,filter*,filter-mapping*,listener*
,servlet*,servlet-mapping*,session-config?,mime-mapping*,welcome-file-list?,erro
r-page*,taglib*,resource-env-ref*,resource-ref*,security-constraint*,login-confi
g?,security-role*,env-entry*,ejb-ref*,ejb-local-ref*)". @ vfsfile:/D:/jboss-5.0.
0/server/default/deploy/myapp.war/WEB-INF/web.xml[28,11]

answer:

tomcat對web.xml的元素順序不作校驗，但jboss严格校验各元素的先后順序，只有元素順序正確，才可能部署成功。以下是web.xml的元素順序：

web.xml的元素順序：

 icon?,display-name?,description?,distributable?,context-param*,filter*,filter-mapping*,listener*,servlet*,servlet-mapping*,session-config?,mime-mapping*,welcome-file-list?,error-page*,taglib*,resource-env-ref*,resource-ref*,security-constraint*,login-config?,security-role*,env-entry*,ejb-ref*,ejb-local-ref* 

2.jboss 5 报错：Failed to create a new SAX parser

一个项目，在TOMCAT下运行正常，但移植到JBOSS5下就报错：

很奇怪，经过千辛万苦的查找原因，最终把它解决了。

解决办法：删掉项目中的xerces-2.6.2.jar和xml-apis.jar两个文件！(我的是XerceImpl....jar, xml-api...jar, 删除, 就不会提示ClassCastException).

3. teiid驱动包, 和数据源配置.

驱动包, 放在server下的lib中就ok. 如teiid, oracle...

数据源放在和war包相同的包下.

============================================================================================================

下面是网上摘的, 共参考:

   Jboss从4到5的版本的变化是比较大的,主要是它对包的冲突限制非常严格,在4版本中基本上不是非常严格,如果有包冲突,会自动选择,但在5中回出非常多的转换异常错误,导致项目无法发布,或是发布完成后无法访问,现把这次升级中遇到的错误及解决办法记录如下.

1 The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory

 

将工程路径下的WebRoot下的WEB-INF下的lib里的jsp-api-2.0.jar,servlet-api-2.4.jar删除就OK 了,应该是工程里自带的这两个文件和TOMCAT里的文件冲突导致的ok!

2 org.jboss.util.NestedSQLException: Could not create connection; - nested throwable: (java.lang.NullPointerException); - nested throwable: (org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (java.lang.NullPointerException))
这个是由于配置了数据库的连接池,但是lib中没有相应的连接数据库的驱动,无法产生连接.

 3

1，Jboss 在启动时报Failed to create a new SAX parser 错误。

2，Jboss 在启动时报(java.lang.ClassNotFoundException:   JACC:Error   PolicyConfigurationFactory   :   cannot   find   class   :   null)   

 

解决方案

1,删除 xerces*.jar 和xml-apis*.jar,解决XML 解析器实现冲突。

2,删除jaas.jar and jcr*.jar，解决jaas 实现冲突。

 

4

java.lang.ClassCastException: gnu.xml.aelfred2.JAXPFactory cannot be cast to javax.xml.parsers.SAXParserFactory

原因为:

   项目中的gnujaxp.jar和服务器上的java xml解析器冲突.

 

5

Getting java.lang.ClassCastException: org.apache.catalina.connector.RequestFacade cannot be cast to javax.servlet.http.HttpServletRequest

这个是由于项目中包含的Servlet.jar和服务器上的jar发生了冲突.

 

6 JBoss是自带Hibernate的绝大多数库文件的，所以IDE引入的Hibernate相关库绝对不能随着项目打包，做法同上，把“package”的勾选去掉即可。我曾被这个问题困扰，因为将Hibernate打进war包的结果就是JBoss将在程序运行的时候报出下面的错误信息：

org.jboss.resource.adapter.jdbc.WrapperDataSource cannot be cast to javax.sql.DataSource

这个问题非常的搞,即使把hibernate等的包都搞掉可能还会出问题,我在这边被搞了好久,还好解决了,

总结一下

1 可能是hibernate包冲突问题.

2 可能是项目中的数据库驱动和服务器上数据库驱动重复,导致冲突

3 这个很隐蔽,可能有的包中含有Javax.sql.DataSource,也会冲突,我查到的就有一个,class12.jar

 

总之来说Jboss5是一个很让人头疼的版本.
