当创建link时，你必须是哪个user连接 remote database 访问数据
下表解释了不同user 如何调用database link:
 User Type

usre 类型		 Sample Link Creation Syntax

创建link的语法
 Connected user  ---connetcted user 不是创建link的user，只是可以访问这个link的user
一个本地user可以通过指定username和pwd访问database link，那么他就是connected user。
system 通过public link 查询，这时connected user是system，并且remote数据库会连接到system schema		  CREATE PUBLIC DATABASE LINK hq USING 'hq';
 Current user  --global user必须有 X.509 认证（一个SSL-authenticated enterprise user）并且这个user 必须可以调用这个database link。current user 是oracle security的一个方面。

详情可以参见 oracle database advanced security. administrator 手册中的global security 相关信息		  CREATE PUBLIC DATABASE LINK hq CONNECT TO CURRENT_USER using 'hq';
 Fixed user  --当定义创建定义一个database link 时，Fixed user 的username/password 会出现在定义语句中。
当一个link中包含了fixed user的用户名和密码，那么这个用户名和密码将用于连接remote database.		  CREATE PUBLIC DATABASE LINK hq CONNECT TO jane IDENTIFIED BY doe USING 'hq';

added on line under
:gotTmpdir
set JAVA_OPTS=%JAVA_OPTS% -agentlib:jdwp=transport=dt_socket,server=y,address=8000 -Xms256m -Xmx1024m

at here, we added listen for 8000, and also add memory for tomcat jvm.


2nd stp:
confin the eclipse
1, open "Debug Configurations" dialog window.
2, found the "Remote java Application" and right click ->  click "new" action
3, select connect tab and config the project which deploy to war.
4, select source tab, and added the projects what would u want debug.

for now every things is okay, we start tomcat.
tomcat should be listen foe 8000 and waiting for that.
start the debug that 2nd stp.

后面看到文章:http://hiok.blog.sohu.com/66514288.html,我出的问题和这篇文章上差不多.
根据上面讲的 将hibernate.cache.provider_class=org.hibernate.cache.EhCacheProvider换成hibernate.cache.provider_class=org.hibernate.cache.HashtableCacheProvider后在windows 下面又可以running了.
还没搞明白什么原因,先记着吧,正好尝试丢掉D版Windows,有时间再回来探个究竟.

第一次发现这个网站。貌似很强大，很多东西都不用自己写了，里面有很多模板，想当初写游戏是怎么没看到这个东东啊，幸亏是付费的，不然真的是悔死了，呵呵。
