struts 2とfckeditorの統合
struts 2では、デフォルトのactionはserverltと同様に接尾辞(.action)がないため、このときはアドレスにアクセスし、serletである可能性が高く、actionである可能性が高い.本稿で使用するfckeditorは、画像をアップロードする際にservletの機能を利用しているが、この場合もstruts 2がプロジェクトで使用されている場合、struts 2はデフォルトでこのアドレスをブロックしsturts 2処理に渡す.そのため、画像を正常にアップロードしたり閲覧したりする機能がありません.
具体的な統合プロセスは簡単ですが、ここではstruts 2のactionを修正し、アップロードされた画像のアドレスをfckeditorに渡して処理します.
