SimpleWebScript and Alfresco 3.4 ... broken?

exel88

Alfresco version: Community v3.4.0 (both C and D version) (with tomcat and mysql installation bundle)
OS: Windows 7 Professional - English
IDE: Eclipse Helios

Hello to everyone.

In the last days, you're seen, I've had some problems with a Java Backend Web Script development.
For ensure wich wasn't me the problem, I've tried to follow the tutorial on http://wiki.alfresco.com/wiki/Java-backed_Web_Scripts_Samples for deploy the SimpleWebScript.
I followed instructions to the letter (for Alfresco 3.3 and beyond)! But, this is the result:

Community v3.4.0 (c 3335) schema 4,113

This is the files tree:

.jar file in <Alfresco>/tomcat/webapps/alfresco/WEB-INF/lib or class files in <Alfresco>/tomcat/webapps/alfresco/WEB-INF/classes
web-scripts-application-context.xml - <Alfresco>/tomcat/webapps/alfresco/WEB-INF/classes/alfresco
simple.get.desc.xml  - <Alfresco>/tomcat/webapps/alfresco/WEB-INF/classes/alfresco/templates/webscripts/org/alfresco/demo
‍‍‍‍‍

And, this is the manifest.**** inside the JAR:

Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.1
Created-By: 19.0-b09 (Sun Microsystems Inc.)
‍‍‍‍‍

What I've missed?

Is my Alfresco installation broken?

Andrea

If I add a template file (simple.get.html.ftl) as this:

<html>
&nbsp;&nbsp;&nbsp;<body>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<p>${status.code}</p>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<p>${status.message}</p>
&nbsp;&nbsp;&nbsp;</body>
</html>&nbsp;&nbsp;&nbsp;
‍‍‍‍‍‍‍‍

And

<format default="html">argument</format>‍

into simple.get.desc.xml.

This is the response:

<html>
&nbsp;&nbsp;&nbsp;<body>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<p>200</p>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<p></p>
&nbsp;&nbsp;&nbsp;</body>
</html>&nbsp;&nbsp;&nbsp;
‍‍‍‍‍‍‍‍

For one moment, I was very Happy for this, but… if I change some data, if I make any operation, if I launch exception (e.g. webscript exception with 400 code), AND if I delete my JAR, the response is still the same!!!

I think the problem is in Alfresco. It doesn't recognize the class files and it manages the Java backend webscript as a simple webscript without java code. How … ?

ops:

Anyone have the same problem?

mrogers

The web script implementation is rock solid, otherwise Share would not work and there would be hundreds of unit test failures.

I find your description unclear but I do note that I don't see your Java Backed Web Script being registered anywhere.

exel88

Thank you for your reply mrogers.

I find your description unclear but I do note that I don't see your Java Backed Web Script being registered anywhere.

Me too.

Off course, this is the problem.
I'm new on Alfresco Web Script development, but I've only one problem: deployment!

I followed the Alfresco Wiki and "Alfresco 3 Web Services" book where is described step by step webscript deployment. The problem is in the directory path I used (I think).

Where I can put the files? :shock:

This morning I've traied another example.

HelloworldJavaWebScript.java

package com.packtpub.a3ws.samples.ch07;

import java.util.HashMap;
import java.util.Map;
import org.springframework.extensions.webscripts.Cache;
import org.springframework.extensions.webscripts.DeclarativeWebScript;
import org.springframework.extensions.webscripts.Status;
import org.springframework.extensions.webscripts.WebScriptRequest;


public class HelloWorldJavaWebScript extends DeclarativeWebScript {
&nbsp;&nbsp;&nbsp;@Override
&nbsp;&nbsp;&nbsp;protected Map<String, Object> executeImpl(WebScriptRequest req, Status status, Cache cache) {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Map<String, Object> model = new HashMap<String, Object>();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;model.put("message", "Hello, world");
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return model;
&nbsp;&nbsp;&nbsp;}
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

jhello-context.xml

<bean id="webscript.com.packtpub.a3ws.samples.ch07.jhello.get" 
&nbsp;&nbsp;&nbsp;class="com.packtpub.a3ws.samples.ch07.HelloWorldJavaWebScript" 
&nbsp;&nbsp;&nbsp;parent="webscript" />
‍‍‍‍‍

jhello.get.desc.xml

<webscript>
&nbsp; <shortname>jhello</shortname>
&nbsp; <description>Another try</description>
&nbsp; <url>/jhello</url>
&nbsp; <authentication>none</authentication>
&nbsp; <format default="html">argument</format>
</webscript>
‍‍‍‍‍‍‍‍‍

jhello.get.html.ftl

<html>
<body>
<p>If it doesn't work, it will be a tragedy!</p>
<p>${message}</p>
</body>
</html>
‍‍‍‍‍‍‍‍

I think files are correct. It's wrong?

I've compiled JAVA into CLASS and this is my directory:

com/packtpub/a3ws/samples/ch07/HelloWorldJavaWebScript.class
‍‍‍

Now, the problem is the files' location. I founded many location, many classpath and more. But, none is the correct place.

WHERE? XD I don't understand this. Where I could put che class file? JAR file (WEB-INF/lib doesn't work)? Descriptor and template files? Which what folder tree?

Actually, this is my situation:

…\WEB-INF\classes\alfresco\templates\webscripts\com\packtpub\a3ws\samples\ch07
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; . jhello.get.desc.xml
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; . jhello.get.html.ftl
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; . jhello-context.xml

In addition to my last post, I already know which Alfresco needs to be restarted for see the new jar file.

Web Script doesn't work also if I used .jar instead .class files.
I used ANT project to build this jar, and here it is:

       […]
   
        <!– Execute: ant -f build.xml  –>

       […]

   <target name="compile" depends="init">
      <javac srcdir="${basedir}/src" destdir="${basedir}/build" classpathref="libs">
      </javac>
   </target>

   <path id="libs">
      <fileset dir="../alfresco-community-sdk-3.4.b/lib" includes="**/*.jar" />
   </path>

   <target name="archive" depends="compile">
      <jar destfile="${basedir}/deploy/jar/jhello.jar" basedir="${basedir}/build" compress="true" update="true" />
   </target>

</project>

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

At this stage, I put the jhello.jar into …\tomcat\webapps\alfresco\WEB-INF\lib, I restart Tomcat.
Alfresco starts correctly but at this point … .jar are unrecognized.
:?:

Any suggestion?
