Variable substitution at resource property file

[Albert Kao <al...@yahoo.ca>]

I like to do variable substitution at the resource property file.
I had tried this:
Resource property file:
common.name=What is the name?
page.name.01=${common.name}

Jsp file:
<bean:message key="page.name.01" />

The browser displayed the desired message properly.
i.e.
"What is the name?" is displayed properly.
However, there was runtime error at the weblogic console:
can't parse argument number common.name
java.lang.IllegalArgumentException: can't parse argument number common.name
