OGNL Problems During Struts2 Upgrade
Hello,
We are attempting to upgrade our application from Struts2 version 2.0.11.2 to the current version, 2.2.3. As part of the upgrade, OGNL was upgraded from version 2.7.3 to version 3.0.1.
Our JSPs make use of OGNL to call static methods on classes to help with formatting. Here's an example:
<s:property value="@com.example.DateUtils@toDate(promotion.startDate)" />
The DateUtils class has a static toDate method that takes in the passed in promotion.startDate object (which is likely a java.sql.Date) and converts it to a java.util.Date. It does that so that s:property can properly and uniformly format the date for display.
This had worked before the upgrade from 2.0.11.2 to 2.2.3. After the upgrade, it no longer works and the s:property tag doesn't output anything. I put some logging statements in the toDate method and it looks like the toDate method is never being called in the first place.
One thing to note is that the DateUtils has two overloaded static toDate methods: one that takes a String, and the other that takes a Date (or one of its subclasses). This doesn't seem to make any difference as I've tried changing the method name (and the corresponding OGNL expression) and it still failed to work.
On this page:
http://struts.apache.org/2.2.3/docs/version-notes-211.html
I see this note in the "Backward compatibility issues with previous versions" section:
OGNL method calls like "text(key)" now invoke "text(String)" instead of "getText(String)". This affects method calls only, not properties. Some OGNL expressions may need to be updated.
I'm wondering if this is what is affecting me? If so, how do I update the OGNL expression so that it works? I've tried a few things like adding #attr. or simply # to the front of "promotion.startDate" but that didn't seem to work.
Any help is greatly appreciated. Thank you!!!!

(Or struts.xml, the preferred mechanism AFAIK).

Not sure about the 2.0 upgrade path, will defer to someone else.

Posted by "Asleson, Ryan" <Ry...@biworldwide.com>.
I enabled static method access by adding this to struts.xml:
<constant name="struts.ognl.allowStaticMethodAccess" value="true" />
Thanks to the direction I found here under the "Accessing static properties" section:
http://struts.apache.org/2.2.3/docs/ognl-basics.html
And it now works!!! Thank you!!!!

I don't know why the default formatting tags aren't being used. Probably because the app uses a custom content management system but I don't know. There are over 100 files that use this method for formatting dates and I really don't want to change them all!

How do I enable static method access? Is that through OGNL or Struts2?
I don't know why the default formatting tags aren't being used. Probably because the app uses a custom content management system but I don't know. There are over 100 files that use this method for formatting dates and I really don't want to change them all!
