Hi
I have been trying to figure out how to integrate BIRT into an RCP
application when using a scripted datasource.
I've seen this question anwsered elsewhere in the forum but I haven't
managed to get it working.
Especially this thread "Custom classes are not found in
ScriotedDataSource in my RCP app" which had a lot of deprecated things
in it. Is there a good place to find documentation about the
EngineConstants? Checked the javadoc but wasn't that many comments about
it. Also couldn't find the ReportEngineService class used in the example
code.
First of, is it possible to get BIRT to pick up classes in the normal
classpath? I really don't want to copy the classes into the web-inf
folder of the viewer (perhaps this is the old way of doing it).
If not how do you guys deal with packaging and developing your
applications using scripted datasources in a pain less way.
As a base for my test application I use the BIRT RCP Viewer found here:
http://wiki.eclipse.org/index.php/RCP_Example
Using:
BIRT 2.2
Eclipse 3.3
Would be really grateful for responses.
Cheers,
Mike

Thanks option2 seems to work fine :).
In option 1 you say that I should set the classpath before the platform
starts up, where would I do that? I tried adding the code to teh
Activator but that didn't work for me.
Addd this to the Activator:
System.setProperty(EngineConstants.WEBAPP_CLASSPATH_KEY,
System.getProperty("java.class.path"));
Many thanks,
Mike

Hello..
the system property shd be set before starting the BIRT platform when all
the pluggins are loaded..
I mean to say when u say
platform.startup(config);
Furthur the path shd be the location of the custom class files or jar
files which u wud be accessing in ur Java Script code..
e.g if i have created a sample java class DataSource.java in the same
directory as the ExecutreReport.java . then the class path i wud be giving
as "./bin" as after building all the class files for default package wud
be put into bin directory
