jfinal 报异常：java.lang.NoSuchMethodError: javax.servlet.ServletContext.getJspConfigDescriptor

问题:jfinal 报异常：java.lang.NoSuchMethodError: javax.servlet.ServletContext.getJspConfigDescriptor

jfinal 报异常：java.lang.NoSuchMethodError: javax.servlet.ServletContext.getJspConfigDescriptor

HTTP ERROR 500

Problem accessing /admin/site. Reason:javax.servlet.ServletContext.getJspConfigDescriptor()Ljavax/servlet/descriptor/JspConfigDescriptor;

Caused by:java.lang.NoSuchMethodError: javax.servlet.ServletContext.getJspConfigDescriptor()Ljavax/servlet/descriptor/JspConfigDescriptor;

at org.apache.jasper.compiler.JspConfig.findJspProperty(JspConfig.java:259)

这是因为jfinal 是1.2版的，访问时出现以上异常

解决:把工程当中的把JAVA EE 5 Libraries库删掉即可。
