JspFactory的异常的原因及解决办法原因:
     服务器环境Jboss,Java程由Tomcat5.5工程目录直接拷贝,由于WEB-INF/lib下存在jsp-api.jar、servlet-api.jar,与Jboss自带的jar包冲突造成。
 
 解决办法:
     删除WEB工程Lib目录中的jsp-api.jar、servlet-api.jar,重新启动Jboss服务问题解决。 
 
标记:
     在创建工程时,jsp-api.jar、servlet-api.jar这两个jar包都无需手工加入到web工程中,tomcat与jboss都已包含。
 
今天运行以前的一个老项目,不成想抛出下面的异常
org.apache.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: 23 in the generated java file
The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory

上网搜,发现不少人有这个问题,但都没有解决办法。后来想到可能和tomcat6有关,因为我在工程的lib中添加了很多包(一堆什么Spring
依赖),所以把他们一删JSP就不抛异常了。我估计是,工程中和tomcat6 lib中重复的包在加载时是先被加载(也就是tomcat6中相同的包没
有被加载),而工程中的包版本要比tomcat6中的低,造成上面的异常。我对照着tomcat中包,发现工程中出现诸如catalina.jar、jsp-api.jar
、servlet-api.jar等这样的重复包,把它们从工程中删了就应该行了(对于上面的异常,原因应该是包jsp-api.jar)。看来不是什么包都可以一股脑往工程里加啊。
