Scripted DataSet/Source issue

johnalex14

hello,

I recently ran into an issue where i am trying to use a scripted dataSource and dataSet and pass java objects from my application to birt, as i am attempting to add birt to an already implemented application i am not able to alter it too dramatically, and being able to pass values this way would fit my goals to a T. (I followed the example found at http://www.vogella.de/articles/EclipseBIRT/article.html to start)

at this point I created the fake data and DAO and i have gone through about 5000 variations of the following in my dataSets "open" script:

count = 0;
testSpot = new Packages......struts.action.birtServlets.FakeDAO();
testData = testSpot.getTestValue();

I then have the following in my dataSets "fetch" script:
if (count < 31){
row["columnDate"] = testData.get(count).getDate();
row["columnOpen"] = testData.get(count).getOpen();
row["columnHigh"] = testData.get(count).getHigh();
row["columnLow"] = testData.get(count).getLow();
row["columnClose"] = testData.get(count).getClose();
row["columnVolume"] = testData.get(count).getVolume();
count++;
return true;
}
return false;

..now heres where i have issues: I am able to preview both my graph and the actual data in my data set, however when i go to run my viewer on one of my JSP pages it gives errors. It works fine when i run my other rptdesigns, however, it doesnt seem to be finding my java packages, I have looked high and low and gone through every different version i have seen online anywhere (most attempts end up the same as what i have, where it previews, but wont run). Anyhow, i was wondering if anyone has any alternative suggestions to this issue. Thanks in advance, and PS my errors are listed below

John

here are my errors: (as i said i think the issue is my "open" script not finding its package as the fetch errors are just null pointers from the lack of data passed into it by the open)
The following items have errors:

Hi,

which version of BIRT do you use? (sorry i didn't read the post up to the end...i m too lazy to be honest)

The error is saying that it can't find the FakeDAO class.

The tutorial is a bit outdated and it doesn't follow a essential approach:
The report should not be part of the java project! Java sources and reports should be split in two different projects (i think that this is the reason for the viewer not finding your java sources. It just runs fine in the preview because there it adds the project itself to the classpath..but this is jus).
When splitting report and java sources in two different projects you have to remember to add the java project to the classpath of the report project. Therefore right click on the report project in the navigator and add the java project to the report classpath (see instructions here: http://birtworld.blogspot.com/2009/12/birt-designer-classpath-changes.html
)

hope this helps
Christian
