Re: t5: adding http header
Thanks!! Yep, even though java -version on command line shows 1.6, the Eclipse (right click) project --> properties --> java compiler shows using "JDK 1.5 compliance". Changed that to 1.6 and sure enough no complaints on the @Override annotation anymore. And thanks for that typo catch ;-). In fact, off-topic, but in case anyone would like to use this code, the whole expires date can be made redundant by using max-age in the HTTP request header, per RFC 2616 14.21. response.setHeader(CACHE_CTRL, "no-cache, no-store, max-age=0, must-revalidate"); Also see: http://www.mnot.net/blog/2007/05/15/expires_max-age (this also has a link to an excellent tutorial on caches - must read - basic message being cache control is probably best handled by web server, if you can control it, rather than in your application) -- View this message in context: http://tapestry.1045711.n5.nabble.com/t5-adding-http-header-tp3369097p5716463.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

you've got a typo here :)

i haven't tried it but may give it a go l8r, useful looking service!

Re: t5: adding http header
If the compiler complained about @Override, you are problem using a
1.5 JDK and Wulf (I assume) was using 1.6.

RE: t5: adding http header
Wulf: Why (rather how) the @Override annotation ? I actually had to remove
it for it work.
Anyhooo...here is the complete working example (right or wrong, not
sure)...comments welcome...
Step 1. Created a class in your src/main/java -- SERVICES package - where
you will find AppModule.java already installed by Tapestry. In my case, I
created a class called RevalidateHTTPHeader
package org.yourGroupId.yourArtifactId.services;
import java.io.IOException;
import org.apache.tapestry5.services.Request;
import org.apache.tapestry5.services.RequestFilter;
import org.apache.tapestry5.services.RequestHandler;
import org.apache.tapestry5.services.Response;
public class RevalidateHTTPHeader implements RequestFilter
{
private static final String CACHE_CTRL = "Cache-Control";
private static final String EXPIRE_DATE = "Exprires";
public boolean service(Request request, Response response, RequestHandler
handler) throws IOException
{
response.setHeader(CACHE_CTRL, "no-cache, no-store, must-revalidate");
response.setHeader(EXPIRE_DATE, "Sun, 07 Dec 1941 07:55:00 GMT");
return handler.service(request, response);
}
}
Step 2. Within AppModule.java, do two things -
a. declare the following member variable
RevalidateHTTPHeader nocache = new RevalidateHTTPHeader();
b. add the following within contributeRequestHandler method:
public void contributeRequestHandler(OrderedConfiguration
configuration,
@Local
RequestFilter filter)
{
// Each contribution to an ordered configuration has a name, When
necessary, you may
// set constraints to precisely control the invocation order of the
contributed filter
// within the pipeline.
///
// ADD the custom nocache HTTP header(s)
configuration.add("NoCache", nocache);
//
//
configuration.add("Timing", filter);
}
Step 3: Run Jetty to verify/examine headers - I am using Google Chrome -
which has a free HTTP Headers extension.
http://localhost:8080/yourArtifactId/[yourPage]

RE: t5: adding http header
Hello Angelo,
best use a request Filter. For example:
public class IEStandardModeHeader implements RequestFilter {
private static final String HEADER_KEY = "X-UA-Compatible";
@Override
public boolean service(Request request, Response response,
RequestHandler handler) throws IOException {
response.setHeader(HEADER_KEY, "IE=8");
return handler.service(request, response);
}
}
To activate the filter you need to contribute it in AppModule:
public static void contributeRequestHandler(
OrderedConfiguration configuration) {
Configuration.add(...);
}
Hope this helps!
Kind Regards,
Wulf

Hi,
I need to add some http headers into response, like
Access-Control-Allow-Origin: "*", how to achieve this? Thanks,

Thanks, The better way depends on which pages do you want to do this. If it's all, create a RequestFilter and use the Response's setHeader(String name, String value) method. If it's just one, @Inject Response and use the same method. -- Thiago H. de Paula Figueiredo Independent Java, Apache Tapestry 5 and Hibernate consultant, developer, and instructor Owner, Ars Machina Tecnologia da Informação Ltda. http://www.arsmachina.com.br - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
