Problem in jsp regarding dropdown

[itgaurav198]

Hi,
I am using the following code in my JSP. Actually when i submit this jsp to a servlet then it sets the value of location attribute using request.setAttr ibute() and forwards it using RequestDispatch er and include.But when the JSP page reloads there is no effect of if-else.

<% if(request.getAttribute("location").equals("Chandigarh")){ %>
<select name="Location">
<Option value="Chandigarh" selected>Chandigarh</Option>
<Option value="Pune">Pune</Option>
</select>
<%}
else if(request.getAttribute("location").equals("Pune")){%>
<select name="Location">
<Option value="Pune" selected>Pune</Option>
<Option value="Chandigarh">Chandigarh</Option>
</select>
<% }
else{ %>
<select name="Location">
<Option value="Banglore" selected>Banglore</Option>
<Option value="Chandigarh">Chandigarh</Option>
</select>
<% } %>

Thanks

What do you mean by "there is no effect of if-else." What actually happens when the JSP is opened from the servlet?

Hi,
Actually I am now using the following code:

<% if("Chandigarh".equals(request.getAttribute("location"))) {%>
	<select name="l" onchange="submitForm1();">
	<Option value="Chandigarh" selected>Chandigarh</Option>
	<Option value="Pune">Pune</Option>
	<Option value="Banglore">Banglore</Option>
	</select>
	<%}
	else if("Pune".equals(request.getAttribute("Pune"))) {%>
	<select name="l" onchange="submitForm1();">
	<Option value="Pune" selected>Pune</Option>
	<Option value="Chandigarh">Chandigarh</Option>
	<Option value="Banglore">Banglore</Option>
	</select>
	<%}
	else if("Banglore".equals(request.getAttribute("location"))){%>
	<select name="l" onchange="submitForm1();">
	<Option value="Chandigarh">Chandigarh</Option>
	<Option value="Pune">Pune</Option>
	<Option value="Banglore" selected>Banglore</Option>
	</select>
	<%}
	else{%>
	<select name="l" onchange="submitForm1();">
	<Option value="Chandigarh" selected>Chandigarh</Option>
	<Option value="Pune">Pune</Option>
	<Option value="Banglore">Banglore</Option>
	</select>
	<%}%>

It is always showing the else block code result i.e. not depending on the value of request.getAttr ibute("location ");

Thanks

request.getAttr ibute returns an Object. Typecast that to String first if the value passed is a String.
Most probably the values are not being passed properly. Post the code in the servlet that sets the values and the code that opens the JSP.

You can also try to print the values in the JSP to see what values are passed (if any) .

Hi,
Thanks for your support.
The problem has been solved.
Actually the problem was in conditions used.
