在启动过程中的错误在Tomcat中：DB找不到名称 [英] Error in Tomcat during Startup: DB name not found

问题描述

虽然盯着Tomcat的，我收到以下错误：

While staring the Tomcat, I am getting the following error:

SEVERE: Exception looking up UserDatabase under key UserDatabase

我用同样的分贝配置在server.xml中和Tomcat工作正常之前，但由于最后2天，当我改变服务器，并安装一个新的副本，它抛出这个错误。

I used the same dB configuration before in Server.xml and Tomcat was working fine, but since last 2 days when I change the server and install a new copy, it's throwing this error.

在server.xml中定义的GlobalNamingResources如下：

The GlobalNamingResources defined in server.xml are as follows:

<GlobalNamingResources>
<Resource name="jdbc/abcdOracle" auth="Container"
type="javax.sql.DataSource" 
maxActive="100" initialSize="5" maxWait="2000" 
username="xxxxxx" password="xxxxxx" 
driverClassName="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:@xxxxxx.xxxxxx.net:1523:ABCDE"
validationQuery="select sysdate from dual" 
validationInterval="30000"
testWhileIdle="true" testOnBorrow="true" testOnReturn="false"
removeAbandoned="true" logAbandoned="true"
removeAbandonedTimeout="60" /> 
</GlobalNamingResources>

任何人有任何线索如何解决这个问题。
谢谢你。

Anyone have any hint how to solve this issue. Thanks.

推荐答案

我有我的的tomcat-users.xml中引起的XML语法错误此问题。虽然这些误差修改是完全显而易见的，他们花了一些时间来发现和固定：

I've got this issue caused by XML syntax errors in my tomcat-users.xml. Though these erros are totally obvious, they took some time to be found out and fixed:

1。无效的双引号

• 错误：＆LT;作用rolename=<$c$c><$c$c>manager-script<$c$c><$c$c>/>



• 右键：＆LT;角色角色名称=管理脚本/＆GT;

• Wrong: <role rolename="manager-script"/>
  
• Right: <role rolename="manager-script"/>

2。缺少结束双引号

• 错误：＆lt;使用者的用户名=雄猫密码=雄猫角色=经理桂，经理脚本/＆GT;
  


• 右键：＆lt;使用者的用户名=雄猫密码=雄猫角色=经理桂，经理脚本 /＆GT;

• Wrong: <user username="tomcat" password="tomcat" roles="manager-gui,manager-script/>
  
• Right: <user username="tomcat" password="tomcat" roles="manager-gui,manager-script"/>

3。缺少结束斜线

• 错误：＆LT;角色角色名=admin的＆GT;
  


• 右键：＆LT;角色角色名称=管理员 / ＆GT;

• Wrong: <role rolename="admin">
  
• Right: <role rolename="admin"/>

4。属性之间缺少空间

• 错误：＆lt;使用者的用户名=雄猫密码=雄猫角色=经理桂，经理脚本/＆GT;
  


• 右键：＆lt;使用者的用户名=雄猫密码=雄猫角色=经理桂，经理脚本/＆GT;

• Wrong: <user username="tomcat" password="tomcat"roles="manager-gui,manager-script"/>
  
• Right: <user username="tomcat" password="tomcat" roles="manager-gui,manager-script"/>
