Tomcat启动时classloader加蝲��序
Tomcat的class加蝲的优先顺序一�?nbsp;
1.最先是$JAVA_HOME/jre/lib/ext/下的jar文�g�?nbsp;
2.环境变量CLASSPATH中的jar和class文�g�?nbsp;
3.$CATALINA_HOME/common/classes下的class文�g�?nbsp;
4.$CATALINA_HOME/commons/endorsed下的jar文�g�?nbsp;
5.$CATALINA_HOME/commons/i18n下的jar文�g�?nbsp;
6.$CATALINA_HOME/common/lib   下的jar文�g�?nbsp;
�Q�JDBC驱动之类的jar文�g可以攑֜��q�里�Q�这样就可以避免在server.xml配置好数据源却出现找不到JDBC   Driver的情��c��）
7.$CATALINA_HOME/server/classes下的class文�g�?nbsp;
8.$CATALINA_HOME/server/lib/下的jar文�g�?nbsp;
9.$CATALINA_BASE/shared/classes   下的class文�g�?nbsp;
10.$CATALINA_BASE/shared/lib下的jar文�g�?nbsp;
11.各自具体的webapp   /WEB-INF/classes下的class文�g�?nbsp;

Leaders do the right things, while managers do things right.

董锐 — Mon, 23 Aug 2010 08:29:00 GMT

What this means is that leadership involves setting direction, communicating that vision passionately to those they work with, and helping the people they lead understand and commit to that vision. Managers, on the other hand, are responsible for ensuring that the vision is implemented efficiently and successfully.

Warning: Cannot modify header information - headers already sent by ...."
董锐 — Wed, 02 Dec 2009 02:02:00 GMT
If you got this message: "Warning: Cannot modify header information - headers already sent by ...."

如果在执行php�E�序时看到这条警�?"Warning: Cannot modify header information - headers already sent by ...."
Few notes based on the following user posts:

有以下几�U�解��x���?
1. Blank lines (�I�白�?:

Make sure no blank line after  of the calling php script.

���查有 后面没有�I�白行，特别是include或者require的文件。不���问题是�q�些�I�白行导致的�?/span>
 
 
2. Use exit statement (用exit来解�?:

Use exit after header statement seems to help some people

在header后加上exit();

header ("Location: xxx"); 

exit();
 
3. PHP has this annoying problem, if your HTML goes before any PHP code or any header modification before redirecting to certain page, it'll said "Warning: Cannot modify header information - headers already sent by ...." Basically anytime you output to browser, the header is set and cannot be modified.   So two ways to get around the problem:
3a. Use Javascript (用Javascript来解�?: 

 self.location(\"file.php\");"; ?>

Since it's a script, it won't modify the header until execution of Javascript.

可以用Javascript来代替header。但是上面的�q�段代码我没有执行成�?.. 另外需要注意，采用�q�种�Ҏ��需要浏览器支持Javascript.
3b. Use output buffering (用输出缓存来解决):



... HTML codes ...


... PHP codes ...

header ("Location: ....");

ob_end_flush();

?>

This will save the output buffer on server and not output to browser yet, which means you can modify the header all you want until the ob_end_flush() statement.   This method is cleaner than the Javascript since Javascript method assumes the browser has Javascript turn on.   However, there are overhead to store output buffer on server before output, but with modern hardware I would imagine it won't be that big of deal.   Javascript solution would be better if you know for sure your user has Javascript turn on on their browser.
���像上面的代码那��P���q�种�Ҏ��在生成页面的时候缓存，�q�样���允许在输出head之后再输出header了�?br />




———————————————————————————————————————————�?br />
�l�果最后还是这个问题：

原来是php.ini里面的配�|�出了问题，output_buffering参数默认为off的，现在���它设�ؓ”on”���Ｏ�Q�了�?/span>

从php中访问java
董锐 — Tue, 20 Oct 2009 07:03:00 GMT
1、要安装java jdk�Q�安装tomcat

2、安装好apache,php

3、下载php-java-bridge_5.5.4_documentation.zip

4、解压羃php-java-bridge_5.5.4_documentation.zip

5、将解压�~�后根目录下JavaBridge.war拯���到tomcat服务器的webapp目录�?br />
6、启动tomcat服务�?br />
7、在php中��用java只需增加下面一行语句：

http://127.0.0.1:8080/JavaBridge/java/Java.inc); ?>



可以了：


    $date=new Java('java.util.Date');

echo $date->getDate();

?>

�q�行通过�Q�OK!

80端口被占用的解决�Ҏ��:



cmd命��o�H�口

输入netstat -abn ->c:/port80.txt

然后到c盘port80.txt文�g中找到占�?0端口的程序pid�Q�记下pid。打开��d�����理器，点击“查看”/选择列，��N�?#8220;PID(�q�程标识�W?”�Q�然后单�?#8220;�q�程”标签�Q�找�?0端口对应的pid�Q�就可以看到是那个程序占用的了，更改�q�个�E�序的port�Q�再重启�q�个�E�序�Q���更改生效�?br />


不管是Apache�q�是IIS都无法��用已被占用的端口。即每个端口只允�怋�用一�ơ（一般指被一个服务程序所使用�Q��?br />
如果�pȝ��内已安装IIS�q���用了80端口�Q�Http默认端口�Q�，再安装Apache�Q�只要另选一个端口�ƈ不与其他应用冲突卛_���q�行。例如可以将Apache监听的端口改�?1或其他�Q何一个未被��用的端口�?br />
Apache修改监听端口的方法�ؓ�Q?br />
打开 httpd.conf

修改 Listen 80 �?Listen 81

Apache可以同时监听一个以上的端口实现多个Http服务

只要��M���?�?Listen 82 卛_��
