Hi to all,
environment: Eclipse 3.4, BIRT 2.5
I'm developing a standalone application for rendering report.
All works fine, problem arise when I need to explain problems to end user.
For example, if I use a wrong password for the oda connection, I can catch
the error, but this is not much meaningful.
Code example:
try {
IReportRunnable l_reportRunnable = m_engine.openReportDesign(i_reportPath);
}
catch (EngineException l_exception) {
l_exception.printStackTrace();
}
Exception printed is:
--- stdout begin ---
org.eclipse.birt.report.engine.api.EngineException: Error happened while
running the report at
org.eclipse.birt.report.engine.api.impl.RunAndRenderTask.doR un(RunAndRenderTask.java:196)
....omissis...
Caused by: java.lang.NoClassDefFoundError: org/w3c/tidy/Tidy
at
org.eclipse.birt.report.engine.parser.HTMLTextParser.<init>(HTMLTextParser.java:55)
....omissis...
--- stdout end ---
But the real error is explained in the BIRT log:
--- log begin ---
Aug 28, 2009 9:04:57 PM
org.eclipse.birt.data.engine.odaconsumer.ConnectionManager openConnection
SEVERE: Cannot open connection.
org.eclipse.birt.report.data.oda.jdbc.JDBCException: There is an error in
get connection, FATAL: password authentication failed for user "timesheet".
at
org.eclipse.birt.report.data.oda.jdbc.JDBCDriverManager.doCo nnect(JDBCDriverManager.java:229)
....omissis...
Aug 28, 2009 9:04:57 PM
org.eclipse.birt.report.engine.api.impl.RunAndRenderTask doRun
SEVERE: Error happened while running the report.
java.lang.NoClassDefFoundError: org/w3c/tidy/Tidy
at
org.eclipse.birt.report.engine.parser.HTMLTextParser.<init>(HTMLTextParser.java:55)
--- log end ---
So, (apart from the java.lang.NoClassDefFoundError: org/w3c/tidy/Tidy that I
don't understand), the real problem is known to BIRT: password
authentication failed, but from the code I can only report to the user that
there is an error while running the report (which is much less
explicative).
So question is: Is there any way to hook these problems at their origin? Is
there any way to hook BIRT error handler?
Thanks, Luca

Luca,
catch on all Exception intsances instead of just EngineException.
Also you can also check the errors:
if ( !task.getErrors( ).isEmpty( ) )
{
for ( Object e : task.getErrors( ) )
{
( (Exception) e ).printStackTrace( );
}
}
