วิธีการเชื่อมต่อ PSU Passport ด้วย JSP ผ่าน LDAPS
ทดสอบบน : Windows 2008 R2 / IIS 7.5 / Tomcat 7
1. ดาวน์โหลด CA Certificate PSU Passport โดยเลือกเป็น Base 64 ดังรูป
2. จากนั้นทำการ Import PSUCer เข้า keystore ของ java ก่อนประมาณนี้ครับ (ปรับเปลี่ยนตำแหน่งไฟล์ตาม Version ที่ลงครับ (keystore password default : changeit)
c:\>"c:\Program Files\Java\jre1.8.0_31\bin\keytool.exe" --import -file c:\certnew.cer -keystore "c:\Program Files\Java\jre1.8.0_31\lib\security\cacerts"
เป็นอันเสร็จขั้นตอนการติดตั้ง Certificate ในส่วนต่อไปจะเป็น Code คือแยกเป็น 2 file ซึ่งเป็น file class กับไฟล์ GUI ดังนี้ครับ
