I am trying to connect to MS Excel and read it as a DB using below code -

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
        connection = DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};DBQ="+"C:\\excel.xls"+";READONLY=false");
        statement = connection.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
        ResultSet rs = stmnt.executeQuery( query );
        return rs;

But getting following error -

java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
    at sun.jdbc.odbc.JdbcOdbc.createSQLException(Unknown Source)
    at sun.jdbc.odbc.JdbcOdbc.standardError(Unknown Source)

I am using Windows 7 64 bit. Tried with JDK 1.7 (both 32 and 64 bit, by changing from Winodws ->Preferences) but no luck.

MS Office version is 2007.

最后，搞定了。

  1. 一个需要 JDK 32 位。从 Windows-> 首选项将 eclipse 指向 jdk 32 位
  2. 即使在第 1 步之后，系统库仍然指向 64 位。所以删除它并在 Java Build Path->Libraries 下手动更改为 32 位。有了以上几行，它就可以工作了。
