Hi,

You can load the properties file just like this and store the properties object as the context attribute. Now retrieve the properties object into your servlet and then get your property as props.getProperty("") thats all. so that you don't need to loop thorough to set the properties.

InputStream inputStream = getServletContext().getResourceAsStream("/WEB-INF/app.properties");
Properties props = new Properties();
props.load(inputStream);

Hi,

If you really want to do it using the servlets then why don't you use the context Listener. This listener is called when the context is started or reloaded etc.

Hi Bear,

Well you are right its not a good practice. I Myself don't code that way.
But i was only trying to establish a fact.

Hi David,

I think you need to check back on what you have said about the servlets.

It is not absolutely necessary for a servlet to be in a package.

It can exist independently without a package and can be called.

Hi Arjun,

You are right with regards to the mapping in the web.xml.

<servlet>
<servlet-name>HelloWorld</servlet-name> HelloWorld is the java file name
<servlet-class>Users.Ravi.Desktop.CurrentProject.Servlets.HelloWorld</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>

but the only problem is url which you are using to call the servlet. it should be in the following way

http://localhost:8080/HelloWorld/hello

in the above URL you have different parts which are necessary.

http://<servername>:<port>/<context name>/<url-pattern or the name of the jsp>

The context name is the name of the folder of your application in the webapps directory of the tomcat.

Hi Merrill,

you are right i also came to know that it is not possible to use the struts html tags without the struts framework.

Thanks for all of you who have answered....

Hi,
what do you mean by static presentations only?
my requirement is that i need the html:select which automatically selects a particular value from the options, which we pass into the tag.

Hi,

Thanks for the reply. But i mentioned very clearly that i don't want to use the struts framework. i.e No Action Classes, no struts-config.xml nothing.
i only want to use the tag libraries. I had put the struts.jar in the WEB-INF/lib but iam not able to use those taglibs since it insists in the ActionMappings not found...

what do you mean by session refresh. when you refresh the page it submits to the same session but the same information is sent to the server. The solution to this is the page that you are trying to display should be displayed using the response.sendRedirect() instead of request.getRequestDispacther().forward() so that when there is a refresh it will only ask for that page without submitting any data.

Hope iam clear. if you can provide me with how you are navigating then i will be able to explain in more detail.

you can use you gmail account and send mails using your login and password details. but beware of the proxy, if you have one then you need to include that also in the properties.

mail.google.com

Hi,

The first thing you need to do is the make the method that will prepare the URL static so that your servlet can call that method and pass the sessionID as parameter to that method and that will return the URL.

hi all
i have asked this question previously but the solution is not working .
the question is about rediretion form with in the jsp page.

page1.jsp

<form action="page2.jsp">
<input type="hidden" name="source" value="test">
</form>

page2.jsp

<%
if(request.getParameter("source")==null))
{
response.sendRedirect("page1.jsp");
}
%>

after the form is submitted form the page1.jsp it comes to page2.jsp here after the page2.jsp is realised if we refresh the page the request parameter will be null and the page has to be redirected to the page1.jsp this scriplet is present in the page2.jsp this solution is not working .the functionality that i want is after coming to page2.jsp if we refresh the page it should be redirected to the page1.jsp

thanku
