我正在尝试在Vista 64环境中使用ant构建一些docbook / xml文件。

但是，我无法解决此错误消息。有人有建议吗？

C：\ Users \ Robert Admin> ant无法找到tools.jar。期望在C：\ Program Files \ Java \ jre6
\ li b \ tools.jar中找到它。Buildfile：build.xml不存在！建立失败

谷歌搜索，我发现此tools.jar消息是ant无法找到jdk的结果。实际上，C：\ Program Files \ Java \ jre6 \ li b
\ tools.jar是与另一个程序一起安装的JRE（我猜是）。Tools.jar位于此处： C：\ Program Files \ Java \
jdk1.6.0_22 \ lib

我似乎无法告诉Ant查看JDK路径，而只是查看已经存在的JRE路径。（从Ant文档来看，JRE似乎不足）。

更新＃1 。我尝试卸载64位jdk和安装32位jdk。结果：
