Are all Birt plugins needed for a simple report ??
sgeovar
Hi
There are huge bulk of plugins in the plugin directory.
To create a simple report , are all these plugins needed ??
I tried to remove the unwanted plugins.
But I get Nullpointer Exception and Assertion errors.
I am not able to delete even a single plugin eventhough it is not necessary.
Is there any possibility avalible to use only necessary plugins ?
Why Birt application throws error if unwanted plugins are removed ??
Please help me to resolve this issue.
Thanks

Which plugin did you remove. There are several plugins that can be removed if you do not plan on using all BIRT features.

I used the following plugins only. I removed all other plugins
org.eclipse.osgi.services_3.2.0.v20090520-1800.jar
org.eclipse.osgi_3.5.2.R35x_v20100126.jar

org.eclipse.birt.report.engine_2.5.2.v20100210.jar
My servlet invokes Birtengine and get the PDF report.
Engine failes to start. I get NullpointerException and some times AssertionsException
Birtengine code follows.

Hi Jason,
My application is very simple. I created a Report using Eclipse Birt.
This report has a table and uses "SCRIPT DATE SOURCE".
It has been deployed in Weblogic as a webapp.
I invoke a servlet, to get the PDF report.
I used the following plugins only. I removed all other plugins
org.eclipse.osgi.services_3.2.0.v20090520-1800.jar
org.eclipse.osgi_3.5.2.R35x_v20100126.jar
org.eclipse.birt.api_1.0.0.jar
org.eclipse.birt.core_2.5.2.v20100208.jar
org.eclipse.birt.report.engine.emitter.pdf_2.5.2.v20100129.jar
org.eclipse.birt.report.engine_2.5.2.v20100210.jar
My servlet invokes Birtengine and get the PDF report.
Engine failes to start. I get NullpointerException and some times AssertionsException
Please help to fix this issue
Thanks

You will need more plugins than that. Do you need charting or crosstabs?
Jason
sgeovar
No, I don't need charting or crossbars.
It is a simple table report.
Table has 10 columns.
Dataset open and fetch events retrive from the database. That is it calls a java class and that class
returns the list of data . These data are populated in the table.
Open event has the following code
count = 0;
dataDao = new Packages.admin.ReportDaoImpl();
data123 = dataDao.getTrades4(begin, end,fileid);
Fetch event has the following code
if(count < data123.size()){
row["account"] = data123.get(count).getAccountId();
count++;
return true;
}
return false;

I reduced it some in the following list. It can probably be made smaller. BTW this was with 2.5.1

BTW we have a project in the next release to simplify this.
