How to compile an action?
Hi, im'reading the Langham, Ziegler book and i'm trying to compile the
first action:
package cxa.acting;
import org.apache.avalon.framework.activity.Initializable;
import org.apache.avalon.framework.thread.ThreadSafe;
import org.apache.avalon.framework.logger.AbstractLoggable;
import org.apache.avalon.framework.parameters.Parameters;
import org.apache.cocoon.acting.Action;
import org.apache.cocoon.environment.Redirector;
import org.apache.cocoon.environment.SourceResolver;
import java.util.HashMap;
import java.util.Map;
import java.util.Random;
public class RandomAction
extends AbstractLoggable
implements Action, Initializable, ThreadSafe {
protected Random generator;
/**
* Initialize this component
*/
public void initialize() {
// create a random generator
this.generator = new Random( System.currentTimeMillis() );
}
public Map act(Redirector redirector,
SourceResolver resolver,
Map objectModel,
String src,
Parameters parameters)
throws Exception {
// get the range
int min = parameters.getParameterAsInteger("min", 0);
int max = parameters.getParameterAsInteger("max", 100);
int random = this.generator.nextInt(max - min + 1) + min;
if ( this.getLogger().isDebugEnabled() ) {
this.getLogger().debug("Generated random between " + min + "
and " + max + " : " + random);
}
// build resulting map
Map map = new HashMap(1);
map.put("number", "" + random);
return map;
}
}
I saved it as RandomAction.java and then...???
When i try to compile the action it gives me a lot of error probably
because the classpath is not set correctly...
my classpath is:
CLASSPATH=C:\Program Files\j2sdk1.4.2_01\lib;C:\Program
Files\jakarta-tomcat-5.0.16\webapps\cocoon\WEB-INF\lib
what is wrong??
thanks a lot
regards.

i don't think i need that transformer...i read the page but i seem it only
encodes urls, it doesn't change them...
Best Regards,

Can the encodeURL transformer do the work? See:

How to get the request parameters in a transformer?
Posted by Davide <da...@aliceposta.it>.
Hi!
I'm creating a transformer to modify link elements in an xhtml page (i.e.
a, img, link....);
I need to transform links from relative to absolute, so i need to know the
url of the last request to add it to the link...
this is the sitemap:
<map:match pattern="aggregate">
<map:act type="auth-protect">
<map:parameter name="handler" value="navigation"/>
<map:parameter name="use-request-parameters" value="true"/>
<map:generate type="serverpages" src="xsp/mcnavigator.xsp"/>
<map:transform type="cinclude"/>
<!-- adjust the tags position to create an xhtml page -->
<map:transform type="xslt" src="style/mcnavigator.xsl"/>
<!-- My Transformer!!! -->
<map:transform type="AbsoluteLinkTransformer"/>
<map:serialize type="xml"/>
</map:act>
</map:match>
</map:match>
When i call the aggregate pipeline i pass it a parameter link in wich i put
the url of the page i want to retreive (e.i. aggregate?link=www.w3.org),
so... how to get my link parameter in the transformer?
thanks a lot, best regards.

You need to add each Jar file required individually. Using an IDE would be
easier as it does this for you (i.e. you don't need to manually extend your
classpath with each file).
More information on using Eclipse as a Cocoon IDE can be found on the Wiki
at: http://wiki.cocoondev.org

ok thanks a lot. I found that explanation. But my problem is another,
because i'm a real beginner...
I've added to the classpath the WEB-INF\lib dir that contains the jar
files, but i really don't know how to add jar files fo classpath. Yes, i
could add them manually, but i would like to know if it's possible to add
to the classpath all jar files in the dir automatically.
Do you also know some links to learn more about using eclipse to develop
cocoon components?
regards.

Hi Davide,
page 244 of the book details the steps to build your component. You will
need to add the jar files from the Cocoon lib directory to your classpath.
Or use an IDE that does that for you (like Eclipse).
Best regards
