image url in portlet

[Pablo Olmos]

Hello, I'm having a real hard time by trying to display an image with the <img> tag in a portlet. I can't seem to generate the URL appropriately

This is the closest I've come to generating the right url in the doView() method:

java.net.URL img = request.getPortletSession().getPortletContext().getResource("/images/image.jpg");
 
response.getWriter().print("<img href=\""+img+"\" />");

I even tried to encode it like so:

response.getWriter().print("<img href=\""+response.encodeURL(img.toString())+"\" />");

but that throws and Illegal argument exception. becase the url generated is something like this:

file:/C:/liferay/webapps/myapp/images/image.jpg

and the encodeURL method requires the path to start with a "/" or contain "://".

the bottom line question is: how can i get an url for an image that is included in my war archive?

thanks,

Pablo

you can do the following:
if your context is wps(as in the case with IBM Websphere), you can use:
<a href="/wps/images/page.gif">click to see page.gif</a>


hope this helps..

havent tryed bun the spec says that for u not to have problem whith URL encoding u should use the encodeURL() method to get the url specific to the conteiner u use ....

I had the same problem with liferay earlier. While I didnt find a perfect solution, I found a temporary one.

You can place your images in the liferay folder (under tomcat) and then use the "/" in your image. I thik this is a known problem with liferay, I dont know if they have solved it yet or not.

Also using Liferay and stubled upon this old thread.
Without knowing too much about it, the following worked for me

All within the same .jsp:

<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet" %>
<portlet:defineObjects />

<img src='<%=renderResponse.encodeURL(renderRequest.getContextPath() +
"/images/earth.jpg")%>'
alt="Earth" />
