I’m working on an application where I need to use ExtJS for the user interface and Tapestry as my backend framework. I’m fairly new to both technologies but I’ve managed to build some basic form panels in ExtJS.
My main challenge is figuring out how to establish communication between the frontend and backend. Specifically, I want my ExtJS forms to receive and display JSON data that comes from my Tapestry backend services.
What’s the best approach to set up this integration? Are there any specific configurations or patterns I should follow to make the frontend and backend work together smoothly?
Any guidance would be really helpful since I’m still learning both frameworks.
You need proper REST endpoints in your Tapestry app. Create page classes that return JSON using JSONObject or JSONArray classes, and make sure your page methods return a StreamResponse with the right content type. On the ExtJS side, just configure your stores and proxies to hit these Tapestry URLs. Don’t forget CSRF protection - Tapestry generates tokens you’ll need to include in AJAX requests. Also set up URL mapping in your AppModule class so you get clean REST-style endpoints that ExtJS can actually use.
totally! tapestry is great with json! just call your tapestry services using Ext.Ajax.request(). don’t forget to set the right content-type and handle the response in your success callback. it’s pretty straightforward once you get the hang of it!
hey iris! which tapestry version are you on? integration differs a lot between versions. have you checked out tapestry’s json support? what’s your setup like - rest endpoints or tapestry’s ajax components?
