小弟最近用APPFUSE1。91
TOMCAT 4。1
ANT 1。6。2
MYSQL
做系统，各种环境变量设置好了后，按照网上资料，先setup，然后install
但是在install时候，却不能通过，提示错误是：
package-web:
[echo] Preparing tomcat-context.xml for inclusion in war
[war] Building war: E:\1\mytest\dist\webapps\mytest.war
install:
BUILD FAILED: E:\1\mytest\build.xml:1027: java.net.ConnectException: Connection refused: connect
Total time: 5 seconds

转到提示错误的build。xml 的行，主要是：
<!-- ============================================================== -->
<!-- Tomcat tasks - remove these if you don't have Tomcat installed -->
<!-- ============================================================== -->
<taskdef file="${ant-contrib.dir}/tomcatTasks.properties">
<classpath>
<fileset dir="${tomcat.home}/server/lib" includes="catalina-ant*.jar"/>
</classpath>
</taskdef>
<target name="install" description="Install application in Tomcat"
depends="package-web">
<deploy url="${tomcat.manager.url}"
username="${tomcat.username}"
password="${tomcat.password}"
path="/${webapp.name}"
war="file:${webapp.dist}/${webapp.war}"/>
</target>

请问各位达人，什么地方错啊，应该怎么解决啊，小弟感激不尽。
