The problem is that the package names changed after the tutorial was written. Try changing your imports to:

import org.springframework.extensions.webscripts.DeclarativeWebScript;
import org.springframework.extensions.webscripts.Status;
import org.springframework.extensions.webscripts.WebScriptRequest;‍‍‍

thanks for the reply

Q1:After I have done from any thing and come with successful in execution by using the ant . what should I do to make it run in the alfresco ?

Q2:And when I red the tutorial there is difference between the tutorial and the source code . i.e : in the tutorial as I have understood from it . that I should place my workflow in some directory and do some steps to get my workflow done . but the source code I should ant into eclipse the folder then some procedures happen . how can I understand the difference between those two steps?

I hope I get it right

jpotts

The tutorial covers several examples. I don't know which one you are on, but the general way to start and advanced workflow is covered on pages 36 - 38.

All of my examples assume you are editing files within a project in Eclipse. I use Ant to deploy those files from the Eclipse project structure to an exploded Alfresco WAR.

When using jBPM, I find it is often handy to deploy the workflow directly to the repository from the Graphical Process Designer Eclipse plug-in's "Deploy" tab. But that is not necessary. At the time that tutorial was written, the process deployer servlet was always available. It has since been disabled by default, so you have to turn it on if you want to use this. Be aware that it creates a security hole so do not enable it in production.

I strongly recommend that you also follow the example of creating and editing files within some folder structure (an Eclipse project, if you'd like, or something else) separate from the Alfresco code. Then, use Ant to deploy the code to Alfresco.

While developing, it is often faster to use Ant to deploy the files to the exploded WAR. When you are ready to go to production it is probably a better idea to have your Ant build create an AMP that you apply to the Alfresco WAR using the MMT.

For the WebScriptStatus problem, change the import from whatever it is now to:
import org.springframework.extensions.webscripts.Status;

And then change the method declaration to:
executeImpl(WebScriptRequest req, Status status)

I'm not sure why your PostRating.java compile is failing on NodeRef. Make sure you have the following import:
import org.alfresco.service.cmr.repository.NodeRef;

If you are following along with the first-edition tutorials, you may find that the code that accompanied the Alfresco Developer Guide is more up-to-date. The book used many of the first-edition tutorials and in some cases made improvements to the code. The code was also maintained for many releases after the book was published. The code is tagged by chapter and by Alfresco release. So, for example, the workflow chapter is Chapter 7. You may have to check out the code to see all of the tags. Google Code won't let you browse all of them through the UI.
