Network name of this virtual host, as registered in your
Domain Name Service server.
Exactly one of the Hosts
associated with each Engine MUST have a name matching the
defaultHost attribute of that Engine.
in some circumstances, it is desireable that two or more
network names should resolve to the
same virtual host.
<Host name="www.mycompany.com" ...>
...
<Alias>mycompany.com</Alias>
...
</Host>
In order for this strategy to be effective, all of the network names involved must be registered
The
Application Base directory for this virtual host.
This is the pathname of a directory that may contain web applications
to be deployed on this virtual host.
You may specify an
absolute pathname for this directory, or a pathname that is relative
to the
$CATALINA_BASE directory.
appBase="webapps" is the default value.
You can nest one or more
Context elements
inside this
Host element, each representing a different web
application associated with this virtual host.
The
Document Base (also known as the
Context
Root) directory for this web application, or the pathname
to the web application archive file (if this web application is
being executed directly from the WAR file). You may specify
an absolute pathname for this directory or WAR file, or a pathname
that is relative to the
appBase directory of the
owning
Host.
If a symbolic link is used for docBase then changes to the
symbolic link will only be effective after a Tomcat restart or
by undeploying and redeploying the conext. A context reload is not
sufficient.
Do not choose a docBase that starts with your Host's appBase string.
The default appBase is "webapps" so do not choose a docBase like
"webapps-foo." Doing so will lead to deployment errors: see
Bugzilla for details.
The value of this field
must not be set when the Context is
configured using a
META-INF/context.xml file as it will be
inferred by the automatic deployment process.
The
context path of this web application, which is
matched against the beginning of each request URI to select the
appropriate web application for processing.
All of the context paths
within a particular
Host must be unique.
If you specify a context path of an empty string (
""), you are
defining the
default web application for this Host, which
will process all requests not assigned to other Contexts.
問題： 為什么我可以使用http://www.mysite.com:8080/ 去訪問Test Project, 而使用http://localhost:8080/ 卻不能，需使用http://localhost:8080/Test_Project訪問
C:\WINDOWS\system32\drivers\etc\hosts
127.0.0.1 localhost
127.0.0.1 www.mysite.com
這個(gè)問題是“直接使用http://localhost 或 http://www.mysite.com/
訪問開發(fā)的項(xiàng)目”
， 為了達(dá)到這一目的，有以下途徑：
途徑1：
設(shè)置 context path=“” ，如
<Context docBase="Test Project" path="" reloadable="true" crossContext="true" source="org.eclipse.jst.j2ee.server:Test Project"/></Host>
但是這有一個(gè)問題：
使用eclipse servers 新建一個(gè)server，產(chǎn)生配置文件 D:\WorkSpace\MY_DEV\Servers\Tomcat v5.5 Server @localhost-config\server.xml, 修改該自動(dòng)生成的文件
啟動(dòng)server后，這些配置文件將被發(fā)布到tomcat webapps的同級(jí)目錄conf下，而且在發(fā)布時(shí)server.xml的內(nèi)容為eclipse自動(dòng)生成的內(nèi)容，用戶的修改被拋棄。所以為了達(dá)到“直接使用http://localhost 或 http://www.mysite.com/
訪問開發(fā)的項(xiàng)目”
這一目標(biāo)，有兩種方法：
方法一：
直接修改tomcat conf目錄下的server.xml文件。
方法二：
在eclipse中，在自動(dòng)生成的server.xml基礎(chǔ)上添加一個(gè)host
<Host appBase="webapps" autoDeploy="true" name="www.mysite.com" unpackWARs="true">
<Context docBase="Test Project" path="" reloadable="true" source="org.eclipse.jst.j2ee.server:Test Project"/>
</Host>
該修改在"關(guān)閉，再啟動(dòng)"(直接重啟不行)server后，能被更新到tomcat conf下面的server.xml
在項(xiàng)目發(fā)布中，最終生效的是tomcat conf下的server.xml
途徑2：來自http://blog.csdn.net/miqi770/archive/2008/02/20/2109805.aspx，
未嘗試
使用eclipse發(fā)布xm到tomcat
把ROOT目錄刪掉,把xm重命名ROOT
使用http://localhost時(shí)，可以直接訪問自己開發(fā)的項(xiàng)目
