今天启动项目遇见的问题

1.一打开jsp页面就后台报这个

At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger
for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compila 

2.页面一直转，随后接着后台报

 in thread "http-apr-8080-exec-4" java.lang.OutOfMemoryError: PermGen space

解决方法：

第一个，新增jar包，我新增的是tomcat/lib下的jsp-api.jar的jar包

第二个，先修改的tomcat物理路径下的 bin下的catalina.bat

set JAVA_OPTS=%JAVA_OPTS% -server -XX:PermSize=512M -XX:MaxPermSize=512m 

（在下面这一段上加上上面这一段，调大启动堆内存和最大堆内存等）

echo Using CATALINA_BASE:   "%CATALINA_BASE%"

但是没起作用

应该是用eclipse配置的原因，所以，把eclipse的t配置的omcat的参数给调整了一下

加上 -Xms512m -Xmx1024m -XX:MaxPermSize=512m


就不报内存溢出了
