Set a XML DataSource programmatically

Mikey

Hello World, 
 
Here is what I am trying to do:- 
 
I have created a report called test.rptdesign. I have specified a XSD file as the datasource of my report and the report's dataset contains the elements in the XSD schema. 
 
right, now I am want to invoke this report programmatically. I have a Java Object that I have converted to XML (using JAXB) and I now want to set the XML as the datasource for this report at runtime. 
 
ie., While design time, I have specified a XSD schema as my datasource, but while run time I want the report to point to a XML file. Makes sense? How would I go about doing this? 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>
String xmlString = "<application>.................</application>";
ReportDesignHandle reportDesignHandle = (ReportDesignHandle)design.getDesignHandle();
SlotHandle dataSets = reportDesignHandle.getDataSets();
</pre>
 
How can set the xmlString as my dataSource? Any ideas / pointers? 
 
Regards, 
Mikey

Hmm.. not quite. The link shows me how to parse a XML file.

But what I am after is a setting up a XML datasource programatically

Ok. I figured it out.. This is how you do it:- 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>

String xml="<employee><name>mikey</name>...............................</employee>";
config.getAppContext().put("org.eclipse.datatools.enablement.oda.xml.inputStream", newByteArrayInputStream(xml.getBytes()));

</pre>

Mikey,

Any idea how to do this if you want to point the BIRT report to a file to read rather than an input stream?

Or would you need to read the file in and then set the stream?

I've got two datasources, two different XML files, can you set each?

Thanks,

Kevin

Hi Mikey, 
 
I want to implement the same behavior. Currently I have code written in Ruby to connect to the BIRT datasource programmatically but now for performance reasons we want to use the JAXB, can you please.. help me with this? 
As I see you have already implemented the same thing. 
 
It will be a great help if you can share the step or the sample code for this implementation as I am not very good at Java 
 
Thanks in advance, 
Shivani
