Custom Struts portlet error in Liferay 6.0 SP2

[Kristian Gil, geändert vor 12 Jahren.]

Hi all,

I was able to rebuilt a Struts 1 portlet from Liferay 5.1.7 in Liferay 6 SP2 SDK environment. Now while bringing up Tomcat (6.0.32) I'm getting the following errors (looking on internet some guys suggested it was a conflict between several strut jars that I might have but I confirmed that I only have one struts.jar in my portlet on nothing else on Tomcat's lib folder):

If I remove struts.jar from my portlet's lib folder this error dissapears but then the portlet is not able to find strut's taglibs and more errors show up.
I found this Liferay ticket but it seems it's still on Unresolved state.:

http://issues.liferay.com/browse/LPS-4214

Has anyone faced this issue before?

Thanks in advance!
