為今年我的ProsperDays介紹我展示出價以繁榮API的意志… ? 我建立了剪斷Java節目的一個快和骯髒的出價。? (這個節目沒準備好黃金時間作為出價的阻擊的工具,但是它是否是非常接近和一非常有效的演示。? 我說的原因它沒準備好是它缺乏記憶,意味它在同一個目錄在隨後通行證將出價。)
我認為API出價是第1步在一個勇敢的新的世界繁榮借貸。? 一,它容易地考慮到習慣模型。
如此這126線節目做什麼?
它詢問活躍AA-C信用等級目錄… ? 如果目錄通過我延長相信過濾器(硬編碼) ?并且極小值繁榮計算了ROI價值(引起?繁榮,并且地板通過作為參量) ?并且極小的時間餘留在拍賣它將安置一個檢驗測試出價的或一個真正的出價。
什麼是這個代碼的延長的信用要求? 短的答復…非常緊緊。

這Java代碼(我對貢獻了這個代碼 SourceForge繁榮API ?項目).? 它要求Java2WSDL和開放來源工具引起的API類由亞帕基印第安人基礎。

Cool, thanks for sharing! I’ll have to get my jdk installed again at home and give it a shot.
