Hi all,
I need to build a path to an image file in a JSP based on the value passed
to the JSP's action, either using an English button from <context
path>/*en*/closeBtn.gif
or using a French button from <context path>/*fr*/closeBtn.gif. Suppose the
parameter is called lang so the URL is like* .../login.action?lang=<en or
fr>*
**
There are two approaches, each of which has a problem which I need to figure
out.
*1. If the path is built in JSP*
In this case, I need to store the lang value in a variable and use it to
build the path like this:
<s:url value="/" includeParams="none" id="contextPath"/>
<img src="${contextPath}*???*/closeBtn.gif"/>
where ??? is either en or fr. How can I do it? I know lang can be streamed
out like <s:property value="lang"/> but it doesn't work if ??? is substitued
with <s:property value="lang"/>. Is there a way to read lang to a variable?
*2. If the path is built in the action class*
In this case, I need to get context path and use it to build the path. The
path can be stored as a bean property so its value can be accessed in view
using <s:property .../> tag.
The problem is how to get the context path from an action class?
Are there other ways to solve the problem?
Thanks a lot for any comments and help.
