Question

如果它在我的weblogic服务器或我的代码中，我不知道我的错误。任何人都可以解释我的错误日志。

public class Type4Conn{

        public static void main(String ar[])throws Exception{
            String username="SYSTEM";
            String password="system";
    //      java.sql.Driver myDriver = (java.sql.Driver)
    //              Class.forName("weblogic.jdbc.rmi.Driver").newInstance();
    //              String url =  "jdbc:weblogic:rmi";
    //              java.util.Properties props = new java.util.Properties();
    //              props.put("weblogic.server.url", "t3://hostname:port");
    //              props.put("weblogic.jdbc.datasource", "myDataSource");
    //              java.sql.Connection conn = myDriver.connect(url, props);



            //Class.forName("weblogic.jndi.rmi.Driver").newInstance();
            Properties p=new Properties();

            p.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");

            p.put(Context.PROVIDER_URL,"t3://http://192.168.1.188:7001");

            p.put(Context.SECURITY_PRINCIPAL, username);

            p.put(Context.SECURITY_CREDENTIALS, password);

            InitialContext ctx=new InitialContext(p);

            DataSource ds=(DataSource)ctx.lookup("ds_orclmrcos"); // "java:ds_orclmrcos"    java:comp/env/persistence/

            Connection con=ds.getConnection();

            Statement st=con.createStatement();
            st.executeUpdate("insert into TBL_CUSTOMER(CUST_ID, CUST_FNAME, CUST_MNAME, CUST_LNAME,CUST_ADDRESS,CUST_STATUS)"+
            "VALUES('C-002', 'ALVIN', 'C.','TEST','MANILA', 'PERMANENT')");
           // int a=st.executeUpdate("insert into TBL_ values('test','testuser',2)");

            System.out.println(" records inserted");

这是我的代码。我无法理解我的错误。我是网络逻辑的新手..

这是我的错误日志

Answer 1

你的代码 - 删除“Context.PROVIDER_URL”中的双重协议片段。我认为应该是

"t3://192.168.1.188:7001"

Web逻辑：字符串索引超出范围：-16初始化我的上下文
