Jackcess is a pure Java library for reading from and writing to MS Access databases (currently supporting versions 2000-2007). It is part of the OpenHMS project from Health Market Science, Inc.. It is not an application. There is no GUI. It's a library, intended for other developers to use to build Java applications. Jackcess is licensed under the GNU Lesser General Public License. Take a look at our Frequently Asked Questions for more info.

Here are a few snippets of code to whet your appetite. For more extensive examples, checkout the cookbook. And, since Jackcess is heavily unit tested, you can find even more example code in the unit tests.

• Displaying the contents of a table: System.out.println(Database.open(new File("my.mdb")).getTable("MyTable").display());
• Iterating through the rows of a table: Table table = Database.open(new File("my.mdb")).getTable("MyTable"); for(Map<String, Object> row : table) { System.out.println("Column 'a' has value: " + row.get("a")); }
• Searching for a row with a specific column value: Map<String, Object> row = Cursor.findRow(table, Collections.singletonMap("a", "foo")); if(row != null) { System.out.println("Found row where 'a' == 'foo': " + row); } else { System.out.println("Could not find row where 'a' == 'foo'"); }
• Creating a new table and writing data into it: Database db = Database.create(new File("new.mdb")); Table newTable = new TableBuilder("NewTable") .addColumn(new ColumnBuilder("a") .setSQLType(Types.INTEGER) .toColumn()) .addColumn(new ColumnBuilder("b") .setSQLType(Types.VARCHAR) .toColumn()) .toTable(db); newTable.addRow(1, "foo");
• Copying the contents of a JDBC ResultSet (e.g. from an external database) into a new table: Database.open(new File("my.mdb")).copyTable("Imported", resultSet);
• Copying the contents of a CSV file into a new table: Database.open(new File("my.mdb")).importFile("Imported2", new File("my.csv"), ",");
