How To Use Resource Bundle In Struts2

Struts » on Oct 23, 2011 { 5 Comments } By Sivateja

In struts2, if we want to get labels and error messages from an external file then we need to use resource bundle.  The resource bundle in struts 2 is similar to struts 1 but the difference is,  in struts 1 we need to configure the resource bundle name in struts-config.xml, but in 2.x we need to configure our bundle name in struts.properties file.

Remember:
Both our Bundle, and struts.properties files need to be store in classes folder only

Syntax of struts.properties

struts.custom.i18n.resources= your bundle name

Example:

struts.custom.i18n.resources=java4s
(Let my bundle name being java4s)

Syntax of java4s.properties

enter.user   =  User name
enter.pass   =  Password
user.wrong =  You must enter the user
pass.wrong =  Password should be entered
u.p.wrong   =  User or Password is wrong

something like key = value

In action class if any logic is failed then also we get error messages from a bundel.  At this time we need to make it as an actionError, not fieldError.  If we want to display an action error on a browser then in jsp we need to use the tag called <s:actionerror>

We will see this in the next example with programmatic validations

    @Vaseem

    We can write multiple resource bundles specified by providing a comma, some thing like..

    struts.custom.i18n.resources=java4s,java4s2,java4s3…..bla bla

    Hope you will clear.
