Cannot add POJO as data source to simple report [message #255887]

Hi folks:

I am attempting to write a very simple report which uses a very simple
POJO for its data. I cannot seem to get the JavaScript interpreter to
correctly load my POJO class. I have tried copying the class to:

C:\Software\BIRT\eclipse\plugins\org.eclipse.birt.report.vie wer_2.2.0.v20070620\birt\WEB-INF\classes

C:\Software\BIRT\eclipse\plugins\org.eclipse.birt.report.vie wer_2.2.0.v20070620\birt\WEB-INF\lib

C:\Software\BIRT\eclipse\plugins\org.eclipse.birt.report.vie wer_2.2.0.v20070620\birt\scriptlib

Neither has worked.

This is the error I am getting in preview mode:

A BIRT exception occurred.
Plug-in Provider:Eclipse.org
Plug-in Name:BIRT Data Engine
Plug-in ID:org.eclipse.birt.data
Version:2.2.0.v200706221
Error Code:data.engine.BirtException
Error Message:A BIRT exception occurred: Error evaluating Javascript
expression. Script engine error: ReferenceError:
"SpeedometerDataSourceBean" is not defined. (DataSet[Data Set].__bm_open#4)

ReferenceError: "SpeedometerDataSourceBean" is
not defined. (DataSet[Data Set].__bm_open#4)
Script source: DataSet[Data Set].__bm_open, line: 1, text:

This is my class:

package com.mycompany.platform.ui;

public class SpeedometerDataSourceBean {
private String count = "42";

public String getCount() {
return count;
}

public void setCount(String count) {
this.count = count;
}
}

These are my scripts:
"open"

importPackage(Packages.com.supplyscape.platform.ui);

c = new SpeedometerDataSourceBean();

count = c.getCount();

"fetch"
row["COUNT"] = count;

return true;

I can post the design XML if need be.

Any help will be appreciated. Thanks.

You have defined the class in the package

> package com.mycompany.platform.ui; <-- mycompany

and imported the package

> importPackage(Packages.com.supplyscape.platform.ui); <-- supplyscape

It is possible that this is just a typing error.

Yes, I am sorry. This was just a typo when writing it to the newsgroup.
It was a halfhearted attempt to hide the name of my company. The real
code for the class is:

package com.supplyscape.platform.ui;

public class SpeedometerDataSourceBean {
private String count = "42";

public String getCount() {
return count;
}

public void setCount(String count) {
this.count = count;
}
}

I should also add that I also attempted to package the class by itself in
a jar, and then added the following to the manifest found in:

C:\Software\BIRT\eclipse\plugins\org.eclipse.birt.report.vie wer_2.2.0.v20070620\META-INF

like so:

Class-Path: myclass.jar

You need to find the following line in the MANIFEST.MF file:

Bundle-ClassPath: viewer.jar

and change it to:

Bundle-ClassPath: viewer.jar,
myclass.jar

Put myclass.jar in the
C:\Software\BIRT\eclipse\plugins\org.eclipse.birt.report.vie wer_2.2.0.v20070620
directory (the viewer's root directory).

Check if BIRT has been loaded from the C:\Software\BIRT\eclipse\plugins
location and restart Eclipse using the -clean option
Adding myclass.jar to
C:\Software\BIRT\eclipse\plugins\org.eclipse.birt.report.vie wer_2.2.0.v20070620\birt\scriptlib
would have to work.
