I have few jsp pages that need to display some selected values (key value pair) from a properties file at each page load. I thought I'm going to try something like below.
1- Have a servlet with overridden init method to read the file and load the key value pairs in to a hash map
2- Access the map from each page.
The problem is I couldn't figure out how to share the map to the jsp pages.
If I use a java class to load the key value map and return values when needed, I will have to read the property file, each time I create an instance of that class.
Thanks in advance for any suggestions / help to resolve this problem.
Yes Kelvin is right. You can store your map as an attribute in servletcontext.
And sorvletcontext is accessible to each JSP, so you can use it. and if property is going to change per request then you can set map as attribute in session object.
Thanks for all the replies. I'm going to use the ServletContext to hold my map and that prevents me loading the map again and again.
Bear, I looked in to <fmt:message> tag, but couldnt figure out how it would help me to solve the same problem. If you could elaborate it a little bit, that would be great.
Thanks again for your time.
