您好我需要将Linux服务器上的Java应用程序连接到Progress数据库。我用来连接在Linux服务器上配置的odbc,它可以正常工作,从命令行我可以查询。问题是当我尝试从Java应用程序获取连接时,我得到一个空指针。
Java版本1.6.0_45 操作系统:CentOS 6.5版 ODBC进展:工作正常
这是测试de Insert into Progress
的方法体try {
String bd = "dbToWrite";
String url = "jdbc:odbc:" + bd;
String user = "root";
String psw = "root";
Connection con;
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con = DriverManager.getConnection(url, user, psw);
PreparedStatement ps1 = con.prepareStatement("INSERT INTO PUB.\"mo-chsu\" "
+ "(\"c-expt\", \"c-tisu\", \"i-cheq\","
+ " \"c-a#o\", nombre, apellido, "
+ "\"n-tarj\", \"c-cat\", varios, "
+ "\"s-sac\", embar, otros, "
+ "jubi, \"ti-doc\", \"num-doc\", "
+ "\"co-min\", \"n-liq\", fonavi,"
+ " club,\"n-mes\", anioe)"
+ "VALUES (9999,999,9999.99,"
+ "2014,'XXXX','XXXX',"
+ "999,5,888.88,"
+ "1.0,2.0,3.0,"
+ "4.44,9,99999999,"
+ "1,9,3000,"
+ "30.0,9,2014)");
ps1.execute();
con.close();
} catch (Exception e) {
e.printStackTrace();
}
例外是,并没有说太多:
java.lang.NullPointerException
at sun.jdbc.odbc.JdbcOdbcDriver.initialize(JdbcOdbcDriver.java:436)
at sun.jdbc.odbc.JdbcOdbcDriver.connect(JdbcOdbcDriver.java:153)
at java.sql.DriverManager.getConnection(DriverManager.java:582)
at java.sql.DriverManager.getConnection(DriverManager.java:185)
at Main.conexionProgress(Main.java:23)
at Main.main(Main.java:10)
我认为这个问题是关于Java的库...但我可以找到一个女巫。
请帮我一把!谢谢 对不起我的英文:)
