Hi,
I've created 2 separated projects: the first is a Java project that generates the report (rptdesign file) and the second is a dynamic web project based on JSF 2.0 which shows the report generated by the first project using jsp viewer taglib.
In the first project I used a scripted data source and here is my open script:
dataSetHandle.setOpen( "i = 0;\r\n"
+"Pack1 = new Packages.calculMetrics.performanceMetrics.DataSet();\r\n"
+"L = Pack1.getLabels();\r\n"
+"V = Pack1.extractData(L);\r\n"
+"Pack2 = new Packages.calculMetrics.performanceMetrics.OpenedW2D();\r\n"
+"Pack2.openedw2d(V);\r\n"
+"Pack3 = new Packages.calculMetrics.performanceMetrics.ClosedW10d();\r\n"
+"Pack3.closedw10d(V);"
Where L is a list of Strings and V is a vector of classes
When I run my report in the Eclipse viewer I get no problems, same thing if I run it from a report Engine (using HTMLRenderOption()) I get the HTML report with no problem
but when I run it in Birt Viewer from the other project I get a strange error:
Script engine error: ReferenceError: "V" is not defined.
I attached below the stack trace.
Here is what I've done exactly in the web project:
- I created a dynamic web project v2.5
- I deployed Birt Viewer 3.7.1 in a GlassFish server v 3.1.2
- I copied the generated rptdesign file in the root directory of the viewer (D:\glassfish3\glassfish\domains\domain1\applications\birt)
- I copied some libs (SQL Server, Hibernate, ...) into the lib directory
- I copied the jar file of the first project in the scriptlib directory
- I tested the viewer using this jsp page:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http ://www.w3.org/TR/html4/loose.dtd">
<%@ taglib uri="http: //java.sun.com/jsf/core" prefix="f"%>
<%@ taglib uri="http: //java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="/birt.tld" prefix="birt" %>
<html>
<f:view>
<body>
<birt:report id="birtViewer" reportDesign="PMetrics.rptdesign" baseURL="/birt"
height="600"
width="800"
format="html"
isHostPage="false"
reportContainer="iframe"
>
</birt:report>
</body>
</f:view>
</html>
I tested it with other sample reports and it worked perfectly
Environment:
- Eclipse BIRT 3.7.1 (all in one)
- BIRT runtime 3.7.1
- JDK 1.7
- GlassFish Server 3.1.2
- JSF 2.0
- Hibernate Tools 3.4.0
I can't understand why have I to define the vector V in the Javascript code of the second project however it works perfectly in the first one without definition.
Can anyone help me to solve this problem ???

Claude,
As a test could you jar the hibernate config file by itself manually and
drop it in the web-inf/lib directory?

Claude this will really depend on what functions you want available to
the user. For example If you do not want to support flat file data
sources you could remove:
org.eclipse.datatools.connectivity.oda.flatfile_version.jar
