按照以下方式修改service.xml文件，可以在webapps同级目录下创建webapps-pub这样的文件夹，用来管理多个项目。此方法性能存在问题，可用于企业内部无需性能高的系统配置。
<Service name="pub">
<Connector port="9877" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="9444" URIEncoding="UTF-8"/>
<Engine name="pub" defaultHost="localhost">
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase"/>
<Host name="localhost" appBase="webapps-pub"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
</Host>
</Engine>
</Service>
<Service name="config">
