just starting

Hello, 
I was trying to follow an example of creating a scripted report located here: 
<a class='bbc_url' href='http://www.vogella.de/articles/EclipseBIRT/article.html#birtdeploying_tomcat'>Reporting with Eclipse BIRT and Java Objects (POJO's) - Tutorial</a>. 
 
I am using eclipse 3.3 with the Birt plugin. I created a new report project and set it up with a data set etc and created a Mock class in a package located in another project already existing on the workspace. When I slick on the "preview results" i see the report. However when I swap out the dao with an actual DAO it blows up with an error. 
 
A BIRT exception occurred. 
Plug-in Provider:Eclipse.org 
Plug-in Name:BIRT Data Engine 
Plug-in ID:org.eclipse.birt.data 
Version:2.2.2.r22x_v20071212 
Error Code:data.engine.BirtException 
Error Message:A BIRT exception occurred: Error evaluating Javascript expression. Script engine error: TypeError: [JavaPackage gov.faa.ads.dao.impl.CustomerDaoImpl] is not a function, it is org.mozilla.javascript.NativeJavaPackage. (DataSet[setCustomers].__bm_open#4) 
Script source: DataSet[setCustomers].__bm_open, line: 1, text: 
__bm_open(). See next exception for more information. 
Error evaluating Javascript expression. Script engine error: TypeError: [JavaPackage dao.impl.CustomerDaoImpl] is not a function, it is org.mozilla.javascript.NativeJavaPackage. (DataSet[setCustomers].__bm_open#4) 
Script source: DataSet[setCustomers].__bm_open, line: 1, text: 
__bm_open() 
 
I use the following code to load the class in the open script: 
 
customerDAO=new Packages.dao.impl.CustomerDaoImpl(); 
customer=customerDAO.getCustomer("1"); 
 
I even tried to include the class in the WEB-INF folder of the 
 
C:eclipse_europaeclipsepluginsorg.eclipse.birt.report.viewer_2.2.2.r22x_v20071213birtWEB-INF but it still didn't work. 
 
Any suggestions would be great,

Hi pshah,

Are you talking about in the designer or with the deployed viewer?

Thanks for the reply:
I am using the report design build into eclipse. I click on my data set and the EditDataSet pop up appears, where I click on the preview results tab where I get this error.

After further digging, I figured out that I am only getting the error when I try to import DAO that have other dependencies such as hibernate. I even tried to put the spring and hibernate jars inside the birtWEB-INFlibs folder of the plug in to see if the dependencies would be resolved.

On another note, my goal is to expose data that is retrieved from a dao that is backed by hibernate and using spring remoting to connect to the back end. Is this type of setup possible in BIRT?

Thanks a lot

pshah, 
 
Take a look at these posts from the devShare and see if they help you out:

Thanks I looked at the articles, I saw them earlier before I posted the questions but they are a good reference. I wanted to know if you can validate my assumptions:

1.) Using Birt to load a report from eclipce RCP actually starts up an embedded server and then just feeds the page to RCP's viewer.

2.) I'm trying to make some calls to another server using spring remoting to populate the data for the report. I have to use the javascript to make calls to the remote services to do this.

I may have to use another technology as I'm having trouble exposing my spring beans inside the java script. I appreciate your insights.

Thanks,
