GWT JDBC LDAP连接失败 [英] GWT JDBC LDAP connection fails

问题描述

我试图使用jdbc将我的GWT应用程序连接到ldap服务器，但是无法使其工作到目前为止。

这是我的尝试的代码示例连接到它：

 字符串ldapConnectString =jdbc：ldap：// SERVERIP：389 / dc = SERVERNAME，dc = office ，dc = COMPANY，dc = com？SEARCH_SCOPE：= subTreeScope; 
 java.sql.Connection con; 
 try {
 con = DriverManager.getConnection（ldapConnectString，cn = USERNAME，PASSWORD）; 
 
} catch（SQLException e）{
 System.out.println（An error has ocurred !!! Connection failed）; 
 e.printStackTrace（）; 
} 
  

我写的例子是： http://myvd.sourceforge.net/bridge.html

当我运行应用程序时，我得到以下错误消息：

java.sql.SQLException：没有找到适合的驱动程序jdbc：ldap：// SERVERIP：389 / dc = SERVERNAME ，dc = office，dc = COMPANY，dc = com？SEARCH_SCOPE：= subTreeScope

我将非常感谢任何帮助

编辑：
我提供的代码示例在RPC访问的服务器端运行。我在这里下载的lib /目录中包含了2个jar文件： http://sourceforge.net/projects/myvd/files/jdbc%20ldap%20bridge/jdbc%20ldap%20bridge%202.1/jdbc-ldap-2.1.zip/download

解决方案

您通常需要先注册JDBC驱动程序，然后才能连接到后端。

尝试类似

  DriverManager.registerDriver（new com.octetstring.jdbcLdap.sql。 JdbcLdapDriver（））; 
 
  $ b        有关注册驱动程序的方式。
 
I am trying to connect my GWT application to an ldap server using jdbc, but could not make it work so far.

Here is a code sample of my attempt to connect to it:
    String ldapConnectString = "jdbc:ldap://SERVERIP:389/dc=SERVERNAME,dc=office,dc=COMPANY,dc=com?SEARCH_SCOPE:=subTreeScope";
    java.sql.Connection con;
    try {
        con = DriverManager.getConnection(ldapConnectString,"cn=USERNAME","PASSWORD");

    } catch (SQLException e) {
        System.out.println("An error has ocurred!!!  Connection failed");
        e.printStackTrace();
    }
The example I used to write this is: http://myvd.sourceforge.net/bridge.html

When I run the application I get following error message:

java.sql.SQLException: No suitable driver found for jdbc:ldap://SERVERIP:389/dc=SERVERNAME,dc=office,dc=COMPANY,dc=com?SEARCH_SCOPE:=subTreeScope

I would be thankful for any help

Edit: 
The code sample I provided is running on server side accessed by RPC. I included 2 jar files in my lib/ directory downloaded from here: http://sourceforge.net/projects/myvd/files/jdbc%20ldap%20bridge/jdbc%20ldap%20bridge%202.1/jdbc-ldap-2.1.zip/download
解决方案
You generally need to register the JDBC driver before you can connect to the backend.

Try something like 
DriverManager.registerDriver(new com.octetstring.jdbcLdap.sql.JdbcLdapDriver());
before setting up the connection.

More general information on ways of registering drivers.
