JSP在Eclipse中调试时说 "(" , "," , ")" 编译出错 为什么呀 我是在E文下输入的 ???
private void tree(Connection conn, int id, int level) {
...........
}
标记“,”上有语法错误，应为 ; BBS/WebContent ShowArticleTree.jsp标记“,”上有语法错误，应为 ; BBS/WebContent ShowArticleTree.jsp标记“(”上有语法错误，应为 ; BBS/WebContent ShowArticleTree.jsp标记“)”上有语法错误，应为 ; BBS/WebContent ShowArticleTree.jsp
就是 哪个tree 后边的"()"和里边的","出错,没办法编译运行
急 在线等

把相关的代码贴出来可能会比较好点，让人感觉问题更贴近。
