English Joget Workflow provided Bean Shell implementation as several Plugin Types. Please refer to usages section. Thai Joget Workflow ให้การใช้งาน Bean Shell เป็นปลั๊กอินหลายประเภท โปรดดู usages
BeanShell is a small, embeddable Java source interpreter with object scripting language features written in Java.
Thai BeanShell เป็นล่าม Java ขนาดเล็กที่สามารถฝังตัวได้พร้อมคุณสมบัติภาษาสคริปต์วัตถุที่เขียนด้วยภาษาจาวา
BeanShell dynamically executes standard Java syntax in runtime.
Thai BeanShell เรียกใช้งานไวยากรณ์ Java มาตรฐานแบบไดนามิกในรันไทม์
By using BeanShell Plugin, you can type in valid Java codes in plugin configuration and the statements will be executed when the plugin is triggered.
Thai โดยใช้ BeanShell Plugin คุณสามารถพิมพ์รหัส Java ที่ถูกต้องในการกำหนดค่าปลั๊กอินและคำสั่งจะถูกดำเนินการเมื่อมีการเรียกใช้ปลั๊กอิน
No compilation cycle is needed.
Thai ไม่จำเป็นต้องมีวงจรการรวบรวม
