I have a field read from db that contains some HTML and I have to display this field. The HTML contans things like : "..... ...". All images are in a db table with 3 fields:
id - e.g. ./MyImages/img1.jpg
I see 3 ways to implement this:
- create a Filter that find all such img tags in the page and recognize the images starting with ./MyImages. The filter stores the images in the GraphicImageStore and replace the URL with the seam url to retrive the image from store.
- make a servlet mapped to "MyImages". Servlet will access the dao to retrieve the data from db.
- create a tag similar to seamtext that receive a text and make all the necesarry steps (parse, store imgs in ImageStore, replace the IMG tags with calls to the img store).
