Some progress...

I copied the files mail.jar and activation.jar from the smartgwtee-2.4\lib folder to my project's lib folder. I am working within BuiltInDS sample project.

Now my dev mode run gets further along. But I've hit a brick wall (for me anyway) in reading the dev console logs.

When I click the button that inserts a record, which in turn should send an email based on ds.xml operationbinding declaration, the Eclipse console reports:

Code:

But when I click on the hyperlink for "(MailMessage.java:479)", I get an Eclipse alert pop-up:

Code:

Invalid Line Number
479 in not a valid line number in com.isomorphic.mail.MailMessage
OK

Then Eclipse shows an editor window with "Class File Editor," "Source Not Found," "Changed Attached Source?" "Select the location containing the source for 'isomorphic_core_rpc.jar'.

I locate and select the file smartgwtee-2.4/lib/isomorphic_core_rpc.jar (using all possible choices re workspace/file/folder). Returned to Editor window, no apparent change. No line numbers in this editor.

Next, I review the SmartClient Developer Console. The RPC tab shows the following:

RPCRequest

Code:

            "SUBMITDATE":"2011-05-18",

        }, 
        "operationConfig":{
            "dataSource":"REQUESTS", 
            "repo":null, 
            "operationType":"add"
        },

        }
    }
}

            "STATUS":"something"
        }
    }
}

Response

Code:

[
    {
        queueStatus:0, 
        isDSResponse:true, 
        invalidateCache:false, 
        status:0, 
        data:[
            {
                SUBMITDATE:new Date(1305702000000), 
                STATUS:"something", 
                REQUEST_ID:198, 
                EMPLOYEE_ID:12345
            }
        ]
    }
]

My approach, suggested by the java.lang.NullPointerException just prior to the error at com.isomorphic.mail.MailMessage.send(MailMessage.java:479), is to look for the payload of the attempted message send. I'm guessing some format is off that the receiving SMTP server finds unacceptable? But I'm kind of blind at this point, since I am not seeing anything helpful in the logs.

Any advice appreciated. Plain vanilla sample code would also be appreciated.

Thanks.

This was a regression, now fixed. The fix will show up in nightly builds as of tomorrow

Thanks. Wish I'd seen that earlier, would have saved me many hours of frustration.

Unfortunately, your post is not returned by the search term "mail."

I opened new thread on that issue: http://forums.smartclient.com/showth...5461#post65461

This response is much appreciated, thanks!

Followup: The overnight 2.5 build fixed it, I now have basic email functionality. Now on to Velocity! :)
