As part of > the upgrade, OGNL was upgraded from version 2.7.3 to version 3.0.1.
Not sure about the 2.0 upgrade path, will defer to someone else. > > 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)" /> > Can you check you struts.properties for: struts.ognl.allowStaticMethodAccess=true > 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. -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- - - - Jason Pyeron PD Inc. http://www.pdinc.us - - Principal Consultant 10 West 24th Street #100 - - +1 (443) 269-1555 x333 Baltimore, Maryland 21218 - - - -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- This message is copyright PD Inc, subject to license 20080407P00. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
