A solution to the warning message problem in struts2

Recently played with the next SSH, compared to the previous version is not the same, but also stuts2 and struts1 some of the other are similar.

To get to the point:

After the normal operation of the project, there are many such as could not found property [Templatedir]

and other warning messages.

Search a bit, have asked a lot of people, the solution is almost no, so came to the Apache website search A, it seems to mention this.

Reference Address: http://cwiki.apache.org/S2WIKI/troubleshooting-guide-migrating-from-struts-20x-to-21x.html# Troubleshootingguidemigratingfromstruts2.0.xto2.1.x-missingproperties

The main contents are as follows: Missing Properties

This message states the framework searched for a, the value stack and failed to find it.

To hide this messages, turn off the WARN level logging for ognlvaluestack.

eg. Include a new limit category in your log4j.xml file (only log errors or worse):

(personal habits), considering that some friends are not familiar with log4j.

Put a little bit of code

Log4j.properties placed in the SRC directory is good, remember to set up on the system disk log4j.appender.logfile.File corresponding files.

# for Jboss:avoid to setup log4j outside $JBOSS _home/server/default/deploy/log4j.xml
