Eclipse和JSP:java.lang.NoSuchMethodError:javax.servlet.jsp.tagext.TagAttributeInfo.<init>(Ljava/lang/String; ZLjava/lang/String; ZZ)V

Question

我正在使用Eclipse 3.4和WTP 3.0.2并运行一个相当大的动态Web项目.我已经设置了项目,以便我可以在http://127.0.0.1:8080/share/访问它,但每当我这样做时,我都会收到以下错误:

因为上述文件都不是我自己的,所以指出问题的原因是非常困难的.任何想法从哪里开始寻找？

Answer 1

我最后回答了我自己的问题:问题是我添加到Tomcat的必要JAR中是一个冲突的servlet.jar.当我删除它时,错误消失了.
