我已经WAR file在中的webapps文件夹中部署了一个tomcat。当我启动我的tomcat时，如下所示

C:\apache-tomcat-6.0.35\bin>startup.bat

Using CATALINA_BASE: "C:\apache-tomcat-6.0.35"

Using CATALINA_HOME: "C:\apache-tomcat-6.0.35"

Using CATALINA_TMPDIR: "C:\apache-tomcat-6.0.35\temp"

Using JRE_HOME: "C:\Program Files (x86)\IBM\RationalSDLC\Common\Java5.0\jre"

Using CLASSPATH: "C:\apache-tomcat-6.0.35\bin\bootstrap.jar"

我在异常以下得到这个-

SEVERE: Error deploying web application archive DirectoryServer.war

这是我的JAVA版本-

C:\apache-tomcat-6.0.35\bin>java -version

java version "1.6.0_26"

Java(TM) SE Runtime Environment (build 1.6.0_26-b03)

Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)

谁能提供任何建议为什么会这样？
