Hello every one

(i have selected in "Java Classes and Resources" the first packadge  src/main/java)

i'm geting this error:

can anyone help?

regards

[alvesricardo]

I'm just learning how to work with jobss and i don't know java. i'm starting to learn this and understanding this but i need your help

any hint is good! tks

edit:

additional info that may help

eclipse.buildId=unknown
java.version=1.6.0_17
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US
Framework arguments:  -product org.eclipse.epp.package.jee.product
Command-line arguments:  -os win32 -ws win32 -arch x86 -product org.eclipse.epp.package.jee.product

[peterj]

A description of what you are working with and what you are attempting to do might help. It looks like you are using jBPM and Eclipse, but I have no idea what you are with that ("error deploying" does not make sense in this context because deploying usually means copying the app's archive file to the deploy directory, and you clearly are not doing that). I also do not know where you selected "Java Classes and Resources" or why you would select what appears to be a Mavne-based base source directory for that.

[alvesricardo]

ok.

I'm doing the example that cames in the book "jBoss Tools Developer Guide" in chapter 8

this is the idea of the  workflow:

"

1.  Author of an article is submitting an invoice to the publisher.
2.  The invoice arrives at the publisher fnancial department, where a fnancial
     controller checks the invoice for any mistakes.
3.  The fnancial controller may accept or reject the invoice.
4.  If the invoice is rejected, than the author receives a notifcation by email with
     the contact phone number.
5.  If the invoice is accepted, then it is registered (stored in electronic format) and
     the author is paid the fee through an online payment system (such as PayPal).
6.  The invoice "road" ends up here.

"

in the workflow i use some java code (also from the book) for tow actions

- PayInvoiceAction

/**
*
*/
package articles.invoices.actions;

import org.jbpm.graph.def.ActionHandler;
import org.jbpm.graph.exe.ExecutionContext;

/**
* @author ralves01
*
*/
public class PayInvoiceAction implements ActionHandler {

    /**
     * @author ralves01
     */
    private static final long serialVersionUID = -4019711050714975422L;

    /* (non-Javadoc)
     * @see org.jbpm.graph.def.ActionHandler#execute(org.jbpm.graph.exe.ExecutionContext)
     */
    @Override
    public void execute(ExecutionContext executionContext) throws Exception {
        // TODO Auto-generated method stub

       
         //display a start log message
          System.out.println("SEND PAYMENT STARTED!");
          //PUT HERE MORE CODE TO ACCESS AN ONLINE PAYMENT SYSTEM
          //per example, use the ECHOPay for Java
          //display an end  log message
          System.out.println("SEND PAYMENT ENDED!");
          //leave this node
          executionContext.leaveNode("leave payment");
              
    }

}

and

- RegisterInvoiceAction

/**
*
*/
package articles.invoices.actions;

import org.jbpm.graph.def.ActionHandler;
import org.jbpm.graph.exe.ExecutionContext;

/**
* @author ralves01
*
*/
public class RegisterInvoiceAction implements ActionHandler {

    /**
     * @author ralves01
     */
    private static final long serialVersionUID = -4019711050714975422L;

    /* (non-Java doc)
     * @see org.jbpm.graph.def.ActionHandler#execute(org.jbpm.graph.exe.ExecutionContext)
     */
    @Override
    public void execute(ExecutionContext executionContext) throws Exception {
        // TODO Auto-generated method stub
        //extract the invoice information
                String author_name = String.valueOf (executionContext.getContextInstance().getVariable("author_name"));
                String author_email = String.valueOf (executionContext.getContextInstance().getVariable("author_email"));
                String article_name = String.valueOf (executionContext.getContextInstance().getVariable("article_name"));
                String article_url = String.valueOf (executionContext.getContextInstance().getVariable("article_url"));
                String article_fee = String.valueOf (executionContext.getContextInstance().getVariable("article_fee"));
                //check to see if the information were correctly extracted
                System.out.println("Author name:"+author_name);
                System.out.println("Author e-mail:"+author_email);
                System.out.println("Article name:"+article_name);
                System.out.println("Article URL:"+article_url);
                System.out.println("Article fee:"+article_fee);
       
                //PUT HERE MORE CODE TO PROCESS THE INVOICE INFORMATION
                //store the invoice information into a database, XML file, text  
                //file, etc.
                //leave this node
               
                //store the invoice information into a database, XML file, text file, etc.
   
                executionContext.leaveNode("leave register");
               
    }

}

i guess this is the most relevant information...

If you need some more please ask!

Thanks for your attention

edit:

and i'm trying to deployit to Alfresco. and "conection test" works without problem.

[peterj]

Well, that is very good for background information. Now, exactly what did you do that caused those errors to display?

[alvesricardo]

so, i have the work flow with the actions.

i want to  deploy it to Alfresco

- i go to Deployment tab

- i have nothing checked in Java Classes and Resources

- i test conection: "The server conection was successfully tested"

- then i hit Deploy Process Archive button: a error appears

"an exception happened during the deployment of the process

reason:

an unexpected exception caused the deployment to fail"

details: An unexpected exception caused the deployment to fail
Error while deploying, look in the Error Log for more info

- in error log i get:

>>i want to  deploy it to Alfresco

I don't recall seeing anything about Alfresco in JBoss Tools 3 Developer's Guide, but then it has been over a year since I read it. I don't recall installing Alfresco to try out the jBPM examples.

I don't have a copy of the book with me, and I think I will need it to try to figure out what you are doing. I probably still have my Eclipse workspace somewhere from when I went through the examples, let me look that up also.

I still am not sure what you mean by "IF i check the java classes and resources in Java Classes and Resources  area." Where exactly are you seeing this? Mentioning which menus you went through might help; I can find anything with this title under Window | Preferences, nor under Project | Properties.

[alvesricardo]

it doesn't refere Alfresco in the book, but because i then would like to integrate it with alfresco i was already trying it

3 pics attatched

dep1 and dep 2 so you understand better when i try to deploy

in dep 3 you can see the actions i created

[peterj]

Have you tried deploying to just JBoss AS (no Alfresco)? Did that work?

[amar.ghimire]

Hi Peter and Ricardo,

I am in the same pond. I am trying to create a jBPM workflow in Alfresco. For this I downloaded the jboss eclipe IDE. I downloaded jbpm server 3.0.1 & 3.2.3. I get similar error message when trying to deploy my process.

Here is another thread from Rob who seems to have faced the same problem:

http://community.jboss.org/message/396312#396312

Have you guys resolved this issue yet? If so, can you please kindly share your solution to this problem?

BR

Amar
