Unable to read TLD “META-INF/c.tld” from JAR file的
今天重新open project，以前是用jdk1.5、tomcat5开发、部署的，
本次使用jdk1.6、tomcat6部署，结果总是报错，启动时正常，
在通过浏览器访问项目时，出错，
错误信息如下;
解决路径;
在project-name/WEB-INF/lib下jsp-api.jar，就算是在eclipse中Build Path下接触此文件，引入tomcat6中的JSP-API.JAR . SERVLET-API.JAR，
也是不可以的，最后删除project下的此jar，问题解决。

在project-name/WEB-INF/lib下jsp-api.jar，就算是在eclipse中Build Path下接触此文件，引入tomcat6中的JSP-API.JAR . SERVLET-API.JAR，
也是不可以的，最后删除project下的此jar，问题解决。

Unable to read TLD “META-INF/c.tld” from JAR file
I installed the lastest version of JasperServer on my my brand new server based on tomcat6 with jdk6 but on the first page I got the message “Unable to read TLD “META-INF/c.tld” from JAR file…”.
My first try was to downgrade tomcat and jdk to a previous version andit seemed to work. I first thought in a bug somewhere in tomcat and after some time (20 minutes of my precious time!!!!!) my attention got capured by a message in catalina.out “.. file geronimo.jar skiped … contains Servet violation spec….. ”
So JasperServer contains in WEB-INF/lib some servlet libraries?!?! Could be possible it’s not a war made by me so somebody could have made some mistake. Listing the files in WEB-INF/lib i found the entire world of web libraries, included jsp-api. Yes this is the problem!
Tomcat excludes genonimo.jar because it contains Servlet api’s but loads jsp-api located in WEB-INF/lib because no checkis made. No jsp can be compiled because jasper (not jasper reports) compiles from a classloader and jsp-api are located in a different classloader.
Removig jsp-api everything works fine again.
