Deploying Java-backed class under extension classpath

kooroshv

I have installed Alfresco version 3.3G on Windows and in process of evaluating it. Presently, I am trying to make JavaDir Java-Backed example from chapter 11th in "Professional Alfresco Practical Solutions" book to work. I have gotten the example working where I have placed my Java class file under the default installation path:

<Tomcat_Home>\webapps\alfresco\WEB-INF\classes

However, I am having trouble getting it working when I deploy it under the extension classpath as suggested in the book:

<Tomcat_home>\shared\classes\alfresco\extension

Here is the error message I get when starting Alfresco:

Since Alfresco error tells me it is having problem finding the class file, I experimented by deploying the class under <Tomcat_home>\shared\classes. By doing this Alfresco at start time sees my Java class, but then complains about undefined classes such as DeclarativeWebScript. By adding the corresponding Jar files under <Tomcat_home>\shared\lib I got over some of the undefined class errors, but finally I got stuck where it was complaining about 'no matching type' for 'repository'. This seems not to be the right approach.

Looking at the Wiki http://wiki.alfresco.com/wiki/Java-backed_Web_Scripts_Samples#Writing_the_Web_Script_.28Java.29, it does not mention the 'extension' path. Also I could not find any reference to this topic on the forum.

Any suggestions is greatly appropriated here.

For reference here are the listing of the files and their locations:

Via Alfresco Explorer: Company Home -> Data Dictionary -> Web Scripts Extensions -> org -> example -> javadir.get.desc.xml

<webscript>
  <shortname>Folder Listing Utility</shortname>
  <description>Java-backed implementation of listing folder contents</description>
  <url>/javadir/{folderpath}?verbose={verbose?}</url>
  <authentication>user</authentication>
</webscript>‍‍‍‍‍‍

JavaDir class is listed bellow. Note, I changed import path for 'DeclarativeWebScript' and others from 'org.alfresco.web.scripts' to 'org.springframework.extensions.webscripts' because of changes from 3.2 to 3.3 release:

package org.example;

import java.util.HashMap;
import java.util.Map;

import org.alfresco.repo.model.Repository;
import org.alfresco.service.cmr.repository.NodeRef;
//This classes are defined in spring-webscripts-1.0.0.CI-SNAPSHOT.jar which is in 3rd Party project.
import org.springframework.extensions.webscripts.Cache;
import org.springframework.extensions.webscripts.DeclarativeWebScript;
import org.springframework.extensions.webscripts.Status;
import org.springframework.extensions.webscripts.WebScriptException;
import org.springframework.extensions.webscripts.WebScriptRequest;

public class JavaDir extends DeclarativeWebScript
{
    private Repository repository;
    
    public void setRepository(Repository repository)
    {
        this.repository = repository;  
    }
    
    protected Map<String, Object> executeImpl(WebScriptRequest req,
        Status status, Cache cache)
    {
        // extract folder listing arguments from URI
        String verboseArg = req.getParameter("verbose");
        Boolean verbose = Boolean.parseBoolean(verboseArg);
        Map<String, String> templateArgs = req.getServiceMatch().getTemplateVars();
        String folderPath = templateArgs.get("folderpath");
        
        // search for folder within Alfresco content repository
        String nodePath = "workspace/SpacesStore/" + folderPath;
        NodeRef folder = repository.findNodeRef("path", nodePath.split("/"));
        
        // validate that folder has been found
        if (folder == null)
        {
            throw new WebScriptException(Status.STATUS_NOT_FOUND,
              "Folder " + folderPath + " not found");
        }

        // construct model for response template to render
        Map<String, Object> model = new HashMap<String, Object>();
        model.put("verbose", verbose);
        model.put("folder", folder);
        return model;
    }
}

I think you just have the wrong package names.

Assuming that you have the following on your classpath
<Tomcat_home>\shared\classes\

Then
org.example.JavaDir

would need to be in folder
<Tomcat_home>\shared\classes\org\example

chandu7ee

Hi kooroshv,

even i executed the same code perfectly.,only thing that you are wrong was., placing the class file.

go to <alfresco>\tomcat\shared\classes

create org folder and then create example folder (in org folder) copy the class file into this folder.(in example folder)

because your package name was package org.example;

Thankls

kooroshv

Hi guys,
Thanks for replies and suggestions. I tried your suggestions, but still it is not working. Here is what I had done so far. I placed the JavaDir.class file under:

<Tomcat_Home>\shared\classes\org\example

Now when I start Alfresco server, it finds the class, but now I am getting the following error about not finding 'DeclarativeWebScript' class:

So I copied the JAR file spring-webscripts-1.0.0.CI-SNAPSHOT.jar, under:

<Tomcat_Home>\shared\lib

I ended up copying bunch of other JAR files into the same folder. Here the ones I had to copy:

alfresco-repository-3.3G.jar
commons-logging-1.1.jar
freemarker-2.3.13.jar
spring-surf-core-1.0.0.CI-SNAPSHOT.jar

Still I am getting errors at Alfresco start time. Here is the error:

I have a feeling I should not be copying JAR files into 'shared\lib' folder, somehow Alfresco should be using all the needed JARs from:

<Tomcat_Home>\webapps\alfresco\WEB-INF\lib

Any ideas? Could this be a Tomcat configuration issue? I am using Tomcat 6.0.26 and here is my <Tomcat_home>\conf\catalina.properties:

I even tried to add /webapps/alfresco/WEB-INF/lib/*.jar to end of the 'shared.loader' path and got last error again. Any suggestions?

Thanks.

Hi !

Overall, i suppose putting extension classes in shared/classes is an err unfortunate idea! The reason becomes clear once Tomcats ClassLoader hierarchy and its implications are understood, see http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html for an good explanation.
In short terms: The classloader responsible for shared/classes is parent for the individual webapps classloaders, so all webapps will "see" the classes from shared/classes. But not the other way 'round: A class loaded from the "shared" classloader cannot see any class from a webapp, because these classes are loaded from their very own classloader, which the "shared" classloader has no knowledge of.

So, the preferred way of deploying extension is by usinh AMP modules (which are eventually merged into alfresco.war). However, during development this "Build AMP - Update alfresco.war - Deploy alfresco.war - Restart Tomcat - Wait till Tomcat has redeployed alfresco.war" is way to slow, so i use a much simpler approach:

Start Alfresco once
Delete all .war files from tomcat/webapps/ folder
Delete all unnecessary webapps from tomcat/webapps/ folder (usually i only leave alfreso/ folder)
Deploy your extensions right into to tomcat/webapps/alfresco/WEB-INF/classes/….

ANd when your development is done, you may still pack your extensions in an AMP file… :roll:

Hi kooroshv,

Make sure the Spring Framework configuration for registering your Web script Java class.using below code, if you directly copied the code (from e-book)it will give some syntax errors., make sure this file should be with out any errors by opening on any browser.

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

<beans>
   <bean id="webscript.org.example.javadir.get" class="org.example.JavaDir" parent="webscript">
