java - tomcat访问异常-PHP中文网问答

昨天把IDE换到了eclipse上，什么都没改
然后今天启动tomcat后直接访问localhost:8080报了异常(直接使用cmd然后startup启动)

异常信息:

看上去你的 B2CConverter.class 文件坏掉了，试试重新下载个 tomcat

java.lang.NoClassDefFoundError: Could not initialize class org.apache.tomcat.ut il.buf.B2CConverter

这么明显看不到，类没有导进去啊

刚大致看了一下tomcat的源码,按照题主的日志分析是在加载B2CConverter类的时候,需要执行<clinit>里面的程序也就是

这段代码,再根据日志分析,是在加载Charset的时候出现java.lang.ClassFormatError: Truncated class file类截断异常,估计是加载sun.nio.cs里面的字符集类报出来的也就是jre/lib/charsets.jar里面的类。

建议重新编译一下项目,如果还是不行,JDK什么的重新下一遍
