Upgrading from Struts template to tiles
I recently upgraded Struts and instrantly ran into errors relating to using the template tag, which is now deprecated. Here’s a list of changes I had to make when upgrading from Struts template to tiles.
- Add the tiles-related files from the struts distro.
- Replace < %@ taglib uri='/WEB-INF/struts-template.tld' prefix='template' %> with
< %@ taglib uri='/WEB-INF/struts-tiles.tld' prefix='template' %> - Add direct=’true’ to all of my template:put lines. - this solves a NullPointerException issue.
- If one of the items you’ve named in your template is not in it’s referred jsp file, struts will throw the following error:
The requested resource (/zeprs/WEB-INF/templates/whatever) is not available
Try the following:- Add ignore=”true” to the template:get tag
- If this does not solve the problem, add an empty tag to your jsp page:
template:put name='header' direct='true'
So far it’s been a pretty smooth transition. Yeah!
