Hi all,

I'm new at BIRT and trying to work into it. I'm using the book "Integrating and Extending BIRT".
In the initial situation is that I have a jsp file like this:

<%
	java.lang.String teststr = "MyTest";
	session.setAttribute("AppContextKey", teststr);
	java.lang.String stringObj = "This test my Application Context From the Viewer";
	session.setAttribute("AppContextValue", stringObj);
	String redirectURL = "LINK TO URL";
	response.sendRedirect(redirectURL);	
%>

I also have a report file which is named AppContext.rptdesign.

Aferwards I'm trying to display the string in a data item.
The expression of the data item is:

try{
	MyTest.toString();
}catch(e){
	"My Object Was not Found";	
}

If I start run the Application I don't get the String! It can't find the Object.
In the book is and additional code snippet like this:

config = new EngineConfig();
HashMap hm = config.getAppContext();
hm.put("MyTest", stringObj);
config.setAppContext(hm);

Unfortunately I dont't know where to add this and there is not a description about it.

Cheers,
Samet

This code:
config = new EngineConfig();
HashMap hm = config.getAppContext();
hm.put("MyTest", stringObj);
config.setAppContext(hm);

Is only if you are using the engine api. Are you using the Viewer? If so you have to add a jsp page to the viewer with code like:
<%
java.lang.String teststr = "MyTest";
session.setAttribute("AppContextKey", teststr);
java.lang.String stringObj = "This test my Application Context From the Viewer";
session.setAttribute("AppContextValue", stringObj);
String redirectURL = "LINK TO URL";
response.sendRedirect(redirectURL);
%>
and call it before going into the report. the LINK to URL should be the url to view the report.

Hey Jason,

first of all thank you for replying.

Yes, I'm using the BIRT viewer. I chose a wrong description with "Link to URL"
it should be "Linkt to the report" so there is already the link to my report.

Just to clarify:

If have a web project with the jsp file (the code like you can see above) and a project which includes my report.
I can start my jsp file and after that it is forwarding to the report but I still can't get the AppContext in my report to display the variable.

regards,
Samet
