现在所有数据库连接都工作正常,但在我添加领域后抛出以下错误我已经在库中添加了 sqljdbc4.jar。

可能是什么问题?
最佳答案
Caused by: java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver
告诉您在您的类路径中找不到 sql 库。
它需要在您的 tomcat/lib 文件夹中。
来自doc :
To set up Tomcat to use JDBCRealm, you will need to follow these steps:
- If you have not yet done so, create tables and columns in your database that conform to the requirements described above.
- Configure a database username and password for use by Tomcat, that has at least read only access to the tables described above. (Tomcat will never attempt to write to these tables.)
- Place a copy of the JDBC driver you will be using inside the $CATALINA_HOME/lib directory. Note that only JAR files are recognized!
- Set up a element, as described below, in your $CATALINA_BASE/conf/server.xml file.
- Restart Tomcat 6 if it is already running.
关于tomcat - 在 context.xml 中配置 jdbcRealm,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/9075044/
