Hi,all ,This is my experience for Struts
This tonight,I test a Struts Application,The control pannel get me this info:
org.apache.jasper.JasperException: javax.servlet.ServletException: javax.servlet.jsp.JspException: Missing message for key "registration.jsp.title"
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:541)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:417)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:320)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:266)
javax.servlet.http.HttpServlet.service(HttpServlet.java:803)

I was googleing all night,found a lot of resolve way ,but can't;

finally,I examined my resolution,my application.properties is fail of place,
the correct struct is:
/
index.jsp WEB-INF
struts-bean.tld
struts-html.tld
struts-logic.tld
web.xml
struts-config.xml
lib
classes
application.properties
figo
struts
xxx.class
xxx.class
