Tomcat问题the Apache Tomcai Native library which allows optima

Myeclipse部署项目时，tomcat
tomcat一直提示Deployment is out of date due to changes in the underlying project contents. You'll need to manually 'Redeploy' the project to update the deployed archive.
重新部署也没用

tomcat 7.0.11 manager app host manager 访问错误 密码 确保无误
401 unauthorized
you are not authorized to view this page.if you have not changed any configuration files,please examine the file conf/tomcat-users.xml in your installation.that file must contain the credentials to let you use this webapp.
for example,to add the manager-gui role to a user named tomcat with a password of s3cret,add the following to the config file listed above.
note that for tomcat 7 onwards,the roles required to use the manager application were changed from the single manager role to the following four roles.you will need to assign the role(s) required for the functionality you wish to access.
•manager-gui - allows access to the html gui and the status pages
•manager-script - allows access to the text interface and the status pages
•manager-jmx - allows access to the jmx *** and the status pages
•manager-status - allows access to the status pages only
the html interface is protected against csrf but the text and jmx interfaces are not.to maintain the csrf protection:
•users with the manager-gui role should not be granted either the manager-script or manager-jmx roles.
•if the text or jmx interfaces are accessed through a browser (e.g.for testing since these interfaces are intended for tools not humans) then the browser must be closed afterwards to terminate the session.
for more information - please see the manager app how-to.

Tomcat一直显示the catalina_home enviroment variable is not defined correctly
我百度了很多,也设了变量,于是问题从JAVA_HOME变成了CATALINA,然后就怎么弄都是 the catalina_home enviroment variable is not defined correctly.
我在startup.bat中加了
set JAVA_HOME=C:Program FilesJavajdk1.6.0_10
set JRE_HOME=C:Program FilesJavajre6
（这里我有个问题,jdk1.6.0_10目录下也有个jre,那我JRE_HOME是就像上面那么设还是改成jdk1.6.0_10目录下的jre?）
变量我设了这些：
JAVA_HOME C:Program FilesJavajdk1.6.0_10
CATALINA_BASE I:apache-tomcat-7.0.52
CATALINA_HOME I:apache-tomcat-7.0.52
TOMCAT_HOME I:apache-tomcat-7.0.52
PATH %JAVA_HOME%BIN;%CATALINA_HOME%BIN;
CLASSPATH %JAVA_HOME%LIB;%CATALINA_HOME%LIB;

写一脚本，每天凌晨1点，把/data/tomcat/logs 目录里“昨天的log文件”抽出来，打包成tar格式
然后备份到目录data/backup/logs，然后删除/data/tomcat/logs 目录里“昨天的log文件”。
“昨天的log文件”的特征是：1）后缀是“.log ” 2)文件名里有“2012-12-25”格式的昨天日期

反馈要求：
1．linux下，可执行的SH脚本；
2．SH脚本的使用方法；
3．开发要点说明

英语翻译
Along with the HTTP response code,Tomcat also sent back a few lines of
information before the contents of主ndex .html,as shown in Figure 2-4.
All of these lines are HTTP headers.HTTP uses headers to send meta-
information with a request or response.A header is a colon一delimited
name:value pair-that is,it contains the header's name,delimited by a colon
followed by the header's value.肠pical response headers include content-type
descriptions,content length,a time-stamp,server information,and the date the
content was last changed.This information helps a client figure out what is
being sent,how big it is,and if the data are newer than a previously seen
response.An HTTP request will always contain a few headers8.Common
request headers consist of the user-agent details and preferred formats,lan-
guages,and content encoding to receive.These headers help tell a server what
the client is and how they would prefer to get back information.Understanding
HTTP headers is important,but for now put the concept on hold until you
learn a little more about Servlets.HTTP headers provide some very helpful
functionality,but it is better to explain them further with some HttpserVlet
examples.
8.There are no mandatory headers in HTTP 1.0; in HTTP 1.1 the only mandatory header is the
Host header.

tomcat 如何启动,在dos下运行startup.bat后Neither the JAVA_HOME nor the JRE_HOME environment

MyEclipse 部署 Tomcat 出错。

在MyEclipse 10中开发WebProject ，完成后将项目部署到MyEclipse自带的 MyEclipse Tomcat时没问题，但是部署到 Tomcat 6.x 时出错，如图：

为什么呢？如何解决？

tomcat中conf下的Catalina啥意思?
Catalina什么英文单词,啥意思?
