Hello,
i'm trying to use BIRT for building reports of an existing EJB-project.
Therefor i build an .reportDesign-File that uses a simple
ScriptedDataSource named "SylagenScriptedDataSetHandlerMini". That
DataSource is writen in Java and just contains 2 Arrays with some integer
and string values. The Report then just prints out the Array-Data in an
table. That works just fine in the ReportDesigner where i can preview the
correct results. I now tried to invoke the build of reports through the
BIRT-api from an other java-file called "ReportExecutor.java". But even
with all parameters and libarys set in this eclipse project i always get a
ClassNotFoundException when my java-file tries to invoke the RunTask.
Right now i use a RunAndRenderTask but i also tried to seperate RunTask
and RenderTask and got the same Error while starting the seperated
RunTask. In both cases the report is build anyway but the table is not
filled witha ny informations because the connection to the dataSource is
not working over the API.
I hope someone can give me a hint what i'm doing wrong. The exact error is
printed out as:
