Question

I have a table. The table has a column 'Column1' which is of type 'text'.

How can I retrieve the text and store it as a string?

The below is what I attempted. (But it does not work, I get weird characters back, instead of the data within the database)

   public void getConfigurationXML()
   {
       try
       {            
           Class.forName("java.sql.Driver"); 
           Connection conn=(Connection)DriverManager.getConnection(_url,_user,_pwd); 
           Statement st=conn.createStatement(); 

           ArrayList <String[]> result = new ArrayList<String[]>();
           String query ="SELECT Column1 FROM table1";
           ResultSet rs=st.executeQuery(query); 
           int columnCount = rs.getMetaData().getColumnCount();

           while(rs.next())
           { 
               String[] row = new String[columnCount];
               for (int i=0; i <columnCount ; i++)
               {
                   row[i] = rs.getString(i + 1);
               }
               result.add(row);
           } 

           rs.close(); 
           st.close(); 
           conn.close(); 

      } 
      catch(Exception e)
      { 
           Logger lgr = Logger.getLogger(Database.class.getName());
           lgr.log(Level.WARNING, e.getMessage(), e);
      }
   }

If you’re talking about the text datatype that is used for BLOB structures, you can try this:

java.sql.Blob ablob = rs.getBlob(i + 1);
row[i] = new String(ablob.getBytes(1L, (int) ablob.length()));

The reason for the weird characters is that the database stores this as raw bytes instead of the characters that you’re expecting.
