Burton Rhodes created WW-5066:
---------------------------------
Summary: Allow references to struts constants from within the same
(or included) XML configuration files.
Key: WW-5066
URL: https://issues.apache.org/jira/browse/WW-5066
Project: Struts 2
Issue Type: Improvement
Components: XML Configuration
Affects Versions: Future
Reporter: Burton Rhodes
It would be nice to be able to reference Struts constant declaration values
from within the configuration files.
For example, if you wanted to set a common value for "max file upload size",
you could define a constant and reference it in multiple locations from within
struts.xml (or any included xml configuration file)
[struts.xml]
<struts>
...
<!-- Custom Constant Declarations -->
<constant name="my.constant.maxFileSize" value="20971520"/> <!-- Max
size for individual files (20 MB) -->
...
<package>
...
<action name="ActionName" class="com.my.action.class.ActionName">
<interceptor-ref name="myFileUploadStack">
<!-- REFERENCE CONSTANT HERE -->
<param
name="fileUpload.maximumSize">${my.constant.maxFileSize}</param>
</interceptor-ref>
</action>
...
</package>
</struts>
