篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Safran morpho指纹传感器与web java应用程序集成相关的知识，希望对你有一定的参考价值。
我要求将Safron morpho指纹传感器与现有的Java Web应用程序集成。截至目前我只有safron morpho设备。请引导我启用并集成Web应用程序。
答案
这是你的解决方案。请按以下步骤操作：
- 下载这些文件。 https://www.dropbox.com/s/65ztgdzga0l110w/For_Testing.rar?dl=0
- 安装驱动程序，然后使用MorphoTestPage.html测试您的设备。
- 第一次复制HTML代码。
- 然后javascript。
- 然后是servlet。
