        http://www.eclipse.org/webtools/index.html
    2. 配置

1) 配置java-buildpath

2) 配置JDK
TOMCAT˜qè¡Œçš„时候需要JDKåQŒeclipse自动扑ֈ°çš„是jreåQŒå¦‚下图:

3) 配置xml å’?internet ¾~“å­˜

1) no server错误

2) ¾cÀLœªå®šä¹‰é”™è¯¯
  如果你在web project中ä‹É用了(ji¨£n)一些外部的jaråQŒæ¯”如说log4j之类åQŒä½ 
可能在工½E‹çš„classpath中已¾læ·»åŠ äº†(ji¨£n)˜q™ä¸ªjaråQŒä½†æ˜¯è¿è¡Œæ—¶˜q˜ä¼š(x¨¬)找不到类åQ?BR>˜q™æ˜¯å› äØ“(f¨´)˜q™ä¸ªjar没有被copy到工½E‹çš„部çÖv目录çš?WEB-INF/lib目录下，

再加入到工程的classpath中。如果把jar拷到
/webtests/WebContent/WEB-INF/lib目录下，那么˜q™ä¸ªæ—¶å€™webtests

问题。希望以后版本的wtp中能解决˜q™æ ·çš„问题，如果能够自动的把
classpath中设¾|®çš„所有jar都拷åˆ?.deployables目录下就方便äº?ji¨£n)。）(j¨ª)

3) context错误
