Answer 4

2楼的:Cannot create JDBC driver of class '' for connect URL 'null' 
不能创建驱动类,是不是java程序里没有导入连接数据库的程序类?
你要试驱动程序入手考虑了

Answer 5

OJDBC14.JAR我有的
配置文件我检查了又检查啊~~

Answer 6

url="jdbc:oracle:thin:@10.9.2.191:1521:tmsdb" 
这是oracle的

Answer 7

你的数据库连接类里是不是没配置URL啊？？

Answer 8

org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null' 
at org.apache.tomcat.dbcp.dbcp.BasicDataSource.createDataSource(BasicDataSource.java:1150) 
你的URL配置有问题

Answer 9

 tomcat:server.xml
url="jdbc:oracle:thin:@192.168.1.33:1521:guzhang" <resource-ref/> tag我也配了
还有什么问题呢？如果是数据库表结构的变动会出现这样的异常么？

Answer 10

org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null' Caused by: java.lang.NullPointerException就是这个nullpointerexception咋来的

Answer 11

表结构变化不会引起这样的错误。还是配置的问题。确定
<name>url</name>
<value>jdbc:oracle:thin:@127.0.0.1:1521:orcl</value>有这一节吗

Answer 12

谁帮忙看看启动信息
不知道有什么问题没？表结构变化不会引起这样的错误。 还是配置的问题。 确定 
<name>url </name> 
<value>jdbc:oracle:thin:@127.0.0.1:1521:orcl </value> 有这一节吗 你是说server.xml里的？有啊~web.xml里面也配了<resource-ref>的
