Problem While Passing Parameter To Servlet In JSP

[Jagdish Gada]

Hello, I am learning Advanced Java and getting problem while using the JSP while passing parameter to the Servlet. I have a jsp page which is showing the list of the images name which are contained in the server. I am making use of the link as below:
<a href="http://localhost:8050/****/servlet/invert?image.jpg>
But it is not working. In my servlet it is possible to get the name of the image but my image is not displaying. Can anyone help me?

Hey, I am also getting the same problem. When I try to pass a string which is having a parameter of the file gives problem. I am making use of the code below:

<% - One. jsp -%>
<%
ParamValue str => see below
%>
<jsp:include page="One1.jsp">
<jsp: param name = "param" value ="<%= paramValue %>"/>
</ jsp: include>

<% - One2. jsp: -%>
<% System.out.println (request.getParameter ( "param "));%>

How can I write the code which will pass the parameter to servlet in JSP?

You can solve your problem by making changes in the following way:
You can pass the image name in the URL:

<a href = "url?picturenameImage => title of link </ a>

Server side you get the parameter to the query like this:

NomImage String = (String) request.getParameter ( "picture");

It may be possible to do it. If you consider the HTML then it can allow you to position a parameter query, after you put the name of the first parameter = value if you want to put a second & then you put the name of the second parameter = value and so on ...
For example :

<a href ="url? nomPram1 = valeurParam1 & nomPram2 = valeurParam2> title of link </ a>

Server-side method getParameter () of HttpServletRequest object type allows you to recover any parameter.

It is quiet simple, I think you are having some syntax error and that is why you are getting this problem. So, just make use of the code below for your client and server side program and solve your problem:

<a href ="url? image = nomImage"> title of link </ a>

<a href ="url? nomPram1 = valeurParam1 & nomPram2 = valeurParam2"> title of link </ a>
