Re: Reading Cookies
I'm finally getting around to trying to implement reading cookies in my
templates. But the above link doesn't work. Got a new one?

Re: Reading Cookies
Posted by Matt Raible <ma...@raibledesigns.com>.
After some testing, I noticed that this is working, but not as good as I'd
hoped. It seems that the cache is kicking in
and $cookies.getCookie("com.raibledesigns.theme") is only getting called
the first time the page loads. Subsequent requests get the page from the
cache, so a new cookie value is never read. I'm guessing there's no way to
disable the cache for a certain portion of the page? If not, is there
anyway to read cookies every time in a page?
Thanks,
Matt

Re: Reading Cookies
Posted by Matt Raible <ma...@raibledesigns.com>.
Thanks - using this I was able to create a CookieModel plugin:
package org.apache.roller.cookies.plugins.pagemodel;
import java.util.Map;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.jsp.PageContext;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.roller.weblogger.ui.core.RollerSession;
import org.apache.roller.weblogger.WebloggerException;
import org.apache.roller.weblogger.ui.rendering.model.Model;
public class CookieModel implements Model {
private static Log log = LogFactory.getLog(CookieModel.class);
private HttpServletRequest request = null;
public String getModelName() {
return "cookies";
}
public void init(Map params) throws WebloggerException {
PageContext context = (PageContext)params.get("pageContext");
this.request = (HttpServletRequest) context.getRequest();
}
public String getCookie(String cookieName) {
Cookie[] cookies = request.getCookies();
for (int i = 0; i < cookies.length; i++) {
String name = cookies[i].getName();
if (cookieName.equals(name)) {
return cookies[i].getValue();
}
}
log.warn("ERROR: cookie '" + cookieName + "' not found");
return null;
}
}
Then use it in my velocity templates with:
$cookies.getCookie("com.raibledesigns.theme")
To create it, I copied plugins/pluginmodel to plugins/cookieplugin:
/Users/mraible/dev/roller/docs/examples/plugins/cookieplugin
And I had to alter the build.xml quite a bit to get everything to compile:
<project name="cookiemodel" default="dist">
<property name="buildlib" value="../../../../app/target" />
<target name="dist">
<mkdir dir="build" />
<mkdir dir="dist" />
<javac srcdir="src" destdir="build">
<classpath>
<pathelement path="${buildlib}/roller-classes.jar" />
<pathelement
path="${user.home}/.m2/repository/commons-logging/commons-logging/1.1.3/commons-logging-1.1.3.jar"
/>
<pathelement
path="${user.home}/.m2/repository/javax/servlet/servlet-api/2.5/servlet-api-2.5.jar"
/>
<pathelement
path="${user.home}/.m2/repository/javax/servlet/jsp-api/2.0/jsp-api-2.0.jar"
/>
</classpath>
</javac>
<jar basedir="build" destfile="dist/cookiemodel.jar" />
</target>
<target name="clean" >
<delete dir="build" />
<delete dir="clean" />
</target>
</project>
Cheers,
Matt
