JRXmlDataSource.subDataSource ClassCastExcept

2005-11-02 03:27

I'm getting a strange error using JasperReports with JRXmlDataSource. I am calling a subreport with:

((net.sf.jasperreports.engine.data.JRXmlDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("/VigtarnoturVRow/VigtanirView/VigtanirViewRow")

 

this works fine in my local deployment but when I deploy and run my project with Java Web Start I get the following exception:

 

java.lang.ClassCastException

I have been trying to alter my xml libraries in Java Web Start without any luck.

Is there any way to control which XML-implementation jasperreports use ? I would like to be able to use something other than org.apache.crimson as this seems to be where the error comes from.

I managed to make it work. It seems that JasperReports has a depency on crimson jaxp xml parser but somewhere in my setup another implementation is the default.

 

After setting the System Property "javax.xml.parsers.DocumentBuilderFactory" to "org.apache.crimson.jaxp.DocumentBuilderFactoryImpl" it worked.

 

System.setProperty("javax.xml.parsers.DocumentBuilderFactory", "org.apache.crimson.jaxp.DocumentBuilderFactoryImpl");

datasource for a report with two subreports

2005-11-14 05:47

Hi,

I have two subreports C, D which have their own respective DS. C and D are added to another subreport , say Assembling report B,. B is a simple subreport which addes C and D. B is then added to A which is a portrait/landscape report. where B, C, D are created dynamically.

 

Datasources for C and D has been supplied by B as parameters. How can We prepare the DS for B. Is it possible to fill B without DS.

 

I had given the datasource of C to B (just a try) the table is getting printed, but in a wrong fashion.

 

Thanks a lot.
