Hello Everyone,
Recently, i had to develop a website which needed a different URL mapping, it needed a url mapping like /France/Paris (ie: country/city).I looked out for many options, first of all i tried it with url rewriting servlet and implemented a filter with it, but it was not exactly the thing i wanted. So i looked out for other options and finally i found UrlRewriteFilter from tuckey.
I downloaded the jars from www.tuckey.org/urlrewrite and configured that in web.xml file.
I found its configuration too easy, you need to configure that in web.xml under filter tag.
<filter>
<filter-name>UrlRewriteFilter</filter-name>
<filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>UrlRewriteFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Secondly, there is a seperate xml file called urlrewrite.xml that is needed by this filter.
You need to configure url rewriting rules in there. You can also use expression language to define a rule for your URL type.
So, i did someting like this to achieve my goal.
<rule>
<from>^/([a-z\s-] )$</from>
<to type="redirect">%{context-path}/redirectAction.do?country=$1</to>
</rule>
<rule>
<from>^/([a-z\s-] )/$</from>
<to type="redirect">%{context-path}/redirectAction.do?country=$1</to>
</rule>
<rule>
<from>^/([a-z/\s/-] )/([a-z/\s/-] )$</from>
<to type="redirect">%{context-path}/redirectAction.do?country=$1&city=$2</to>
</rule>
<rule>
<from>^/([a-z/\s/-] )/([a-z/\s/-] )/$</from>
<to type="redirect">%{context-path}/redirectAction.do?country=$1&city=$2</to>
</rule>
The above configuration helped me to accept multi spaced url's like www.ujjwalbsoni.blogspot.com/United States Of America/New York
I created an action in struts that gets me the names of countries and cities accordingly and i finally got what i wanted.
Expression for redirect rule was really tedious since i was having multiple spaces in country/city names. But finally, i created and succeeded in making one and using that.
Cheers!!!
