BIRT embedded in the EAR application [message #114311]

Hello,

I would like to know how should I embed BIRT in the EAR application? How
should I specify engine home?

Another question: do you plan to upload BIRT libraries to the Maven
repository?

Best regards,
Piotr Bzdyl

Nobody uses BIRT as embedded library in the EAR application? Or maybe it
is not possible to use it within the EAR?

There are a few ways and options.

Place all required reports and the engine in the EAR/WAR and then access
it via relative positioning, property file or servlet params. Since the
Engine is not thread safe, it should be loaded on start via a
ContextListener.

Place the engine and the reports in a directory that the User whom the
App Server is runnning under has access to. Provide the directory info
via a property file or servlet params (see previous).

Have the engine running as an app ("webapp", daemon/service, jini, etc)
and call it from the Enterprise App. Then you can look it up as a service.

What if I would like to run the engine in the ejb-jar instead of the
WAR? I would like to expose it as the session bean. Isn't it possible to
extend BIRT so I could provide URL as the engine home? Then I could
package BIRT plugins as JAR within my EAR and provide URL using
Class.getResource() method. I want to avoid specifying absolute path in
separate file - I deploy my app as EAR file in different servers with
different environments. Is there any chance that this would be implemented?

I would preffer to include BIRT as a library in the EAR than place it in
the J2EE server directory - I would like to do upgrades of my app just
by replacing old EAR. It will be much harder to update my application if
there is something more then my EAR.

And about thread safety: I read in the tutorial (Integrating BIRT) that
I can use ReportEngine to render many reports - but I can't find
information whether it is thread safe or not. I would like to create
single instance which could be used to render many reports at the same
time. Is this good solution? As I know creating ReportEngine is time and
resource consuming, thus creating new instance every time new report is
rendered is not a good solution.

Best regards,
Piotr

I have an impression that I am the only person using BIRT in the EAR
application... Anybody has an idea like to solve above problems?

Even I am findin hard to embed reports with EAR application. I would like
to do following:

1. create a report design(only design) using BIRT.

2. Then in my web app I want to pass the connection(datasource),
parameters to design to generate the report.

I am finding it hard to do second step. If you have done similar thing,
could you pl. tell me how can I achive this.
