  1. Hello, COM(Jasmin) World!

    Posted on 1月 26th, 2013 by cx20

    COM(Jasmin)

    COM(Component Object Model)はマイクロソフトの提唱するプログラム部品の仕様である。
    COM を用いて開発された部品であれば言語を問わず利用することができる。
    Jasmin 自身には、COM を呼び出す機能を持っていないが、別途ライブラリを経由することで呼び出すことが可能である。
    以下は Jasmin より JACOB(JAVA-COM Bridge) ライブラリを使用した COM クライアントの例となっている。

    IBM により AWT や Swing を置き換える目的で作成された。
    以下は Jasmin による SWT の使用例となっている。

  9. Hello, JDBC Type4(Jasmin) World!

    Posted on 10月 30th, 2012 by cx20

    JDBC Type4

    JDBC(Java Database Connectivity)は、Java 用のデータベース接続 API である。実装方法によりType1~4の4つのタイプが存在する。
    Type4 は DBMS のクライアントライブラリを使用しない Pure Java の DBMS ドライバである。
    以下は Jasmin による JDBC ライブラリの使用例となっている。

    JDBC Type2

    JDBC(Java Database Connectivity)は、Java 用のデータベース接続 API である。実装方法によりType1~4の4つのタイプが存在する。
    Type2 は JDBC と DBMS クライアントの API をマップさせたブリッジドライバである。
    例えば、Oracle であればクライアントライブラリとして OCI が使用される。
    以下は Jasmin による JDBC ライブラリの使用例となっている。
