tomcat AnnotationProcessor classcase
原文http://olivechinese.iteye.com/blog/365498Hi,
I have a web application that was running on tomcat5.5. Now i want
to deploy it on tomcat 6. when runing it, i got an error saying:
org.apache.jasper.JasperException:
java.lang.ClassCastException:org.apache.catalina.util.DefaultAnnotationProcessor
cannot be cast to org.apache.AnnotationProcessor
at org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:522)
at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:356)
After a search, i found that DefaultAnnotationProcessor implements
AnnotationProcessor and in tomcat 6 catalina.jar and jasper.jar both of
them contains AnnotationProcessor interface in the same package. Some
solution was suggested by kind people but it doesn't work for me, which
is adding this line:
<Loader delegate="true" />
to the context element in the context.xml file of tomcat.
Did any body face this problem?
warm regards
根据上面的描述，并修改了tomcat里的context.xml文件，在context 元素下添加
<Loader delegate="true" />
即可
或
I found the solution.
I inserted into server.xml <Loader delegate="true"/> in the context-element.
e.g.:
Code:
<Context path="/esg" reloadable="true" docBase="C:\workspace\esg\esg" workDir="C:\workspace\esg\esg\work">
<Loader delegate="true"/>
</Context>
