Re: refering a web app file with FileRepresentation

[Thierry Boileau]

Hello,

File templateDir=new File("clap:///template");
I don't think a java.io.File can be instantiated with a CLAP URI (CLAP is a 
pure Restlet concept). I just suggested you to create a FileRepresentation from 
either a CLAP or a WAR URI in order to return a Representation of a file.
If you want to build your HTML representations with Freemarker, you can 
either:
- create a TemplateRepresentation with it's template name, which 
requires you to set up the Freemarker configuration as you do but with a 
standard directory => File templateDir = new File("c:/temp/template");
- or create a TemplateRepresentation from a Representation of the 
template. For example:
result = new TemplateRepresentation(new 
FileRepresentation("war:///items/result.tmpl",MediaType.TEXT_HTML), 
configme(), getItem(), MediaType.TEXT_HTML );

I hope this will help you.

Best regards,
Thierry Boileau

Hi Thierry,

            Thanks for your reply, i tried to get the files from classpath
using CLAP.i have "template" directory in the classpath. but it is still not
able to read the files in that folder.actually i am trying to use freemarker
template files stored in my classpath to render output. 
code is ...

public Representation getRepresentation(Variant variant) {
                Representation result = null;
                if (variant.getMediaType().equals(MediaType.TEXT_HTML)) {
                        try {
                                //  page.buildFromBackend(getRequest());
                                result = new 
TemplateRepresentation(getTemplateName(),
                                                configme(), getItem(),
                                                MediaType.TEXT_HTML);
                        }
                        ---
                }
                return result;
        }

Configuration configme() throws IOException{
                Configuration config=null;
                config=new Configuration();
                File templateDir=new File("clap:///template");
                TemplateLoader fileTemplateLoader=new 
FileTemplateLoader(templateDir);
                config.setTemplateLoader(fileTemplateLoader);
                return config;
        }

String getTemplateName() { return "oneitem.ftl"; }

Stack Trace : 
java.io.FileNotFoundException: clap:\template does not exist.

Hello, 


you can use the WAR protocol scheme (used for serving files from a war
application deployed inside a servlet container), or the CLAP one
(looks for "files" from the classpath). 
For example, if your "items" directory is located just under the
"Web-Content" directory: 

FileRepresentation rep=new
FileRepresentation("war:///items/result.jsp",MediaType.TEXT_HTML); 

I would like to precise the FileRepresentation simply gets the content
of the targetted file.

      I am trying to create a web application with restlet. how can i call
a
file in the web application (using relative path).
I went through documentation of restlet, there creating html content in
the
Resource class was explained as shown here.

getResponse().setStatus(Status.SUCCESS_CREATED);
String result="&lt;h3&gt;Item Created. &lt;/h3&gt;";
result += " &lt;p&gt;use &lt;br&gt;
http://localhost:8080/itemRestlet/itemapp/items &lt;br&gt;in
a new browser instance to see the data.&lt;/p&gt;";
Representation rep = new StringRepresentation(result,MediaType.TEXT_HTML);

        The FileRepresentation class can take path of the file you want to
invoke and content type, but here the problem is trying to locate
result.jsp
in the webserver installation directory rather than in webapp.

 FileRepresentation rep=new
FileRepresentation("items/result.jsp",MediaType.TEXT_HTML);

        Can any one please help me to invoke this result.jsp from a
resource?
I am trying to invoke a html/jsp page from web application from a
resource....help me please
