Question

我正在“尝试查找'jdbc.LogDB'时没有找到子上下文'jdbc'。当我尝试从Weblogic获取连接时，已解决''”错误。我创建并测试了数据源，它正在工作。还创建了目标服务器。数据源名称为“jdbc / LogDb”。下面是我写的测试代码。

public class TestUtils {
    private static final Logger logger = LoggerFactory.getLogger(TestUtils.class.getName());
    public DataSource ds = null;
    public String testConnectionPool()  throws SQLException {
        Context ctx = null;
        Hashtable ht = new Hashtable();
        Connection conn;
        String result = "";

        ht.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
        ht.put(Context.PROVIDER_URL, "t3://localhost:7001");
        ht.put(Context.SECURITY_PRINCIPAL, "weblogic");
        ht.put(Context.SECURITY_CREDENTIALS, "weblogic");


        try {
            ctx = new InitialContext(ht);
            ds = (DataSource) ctx.lookup("jdbc/LogDB");
            logger.debug("Weblogic Connection Pool Created");



        conn = ds.getConnection();
        Statement stmt = conn.createStatement();
        stmt.execute("some sql");
        ResultSet rs = stmt.getResultSet();

        if(rs.next()){
            result = result + rs.getString(1);
        }
        stmt.close();
        conn.close();
        } catch (NamingException e) {
            logger.error("Naming Exception occured at connect: " + e.getMessage());
        } catch (Exception e){
            logger.error("Exception occured at connect: "+ e.getMessage());
        } finally {
            try {
                if (ctx != null) {
                    ctx.close();
                }
            }
            catch (Exception e) {
                logger.error("Ctx Error");
            }
        }
       return result;
    }
}

我尝试了以下名字 “Java的：JDBC / LogDb” “java：comp / env”变种等。
