Subreport with XML-Datasource

[gombs]

High,

 

I have an Subreport from an XML-Source, it works alone without problems. But when I insert this as a Subreport to an other Report I become this message:

 

1286293 [mv_atos_part subreport filler] WARN query.JRXPathQueryExecuter - The supplied org.w3c.dom.Document object is null.

 

The Parentreport have the same XML-Source ( only an other XPATH Expression ) I have the option selected that the XPath expression from report should be used.

 

What is going wrong?

 

friendly greets to all other iReport-users

there are 2 things you need to set when u add a subreport to a main.

 

1) the subreport connection expression. ie

 

((net.sf.jasperreports.engine.data.JRXmlDataSource) $P{REPORT_DATA_SOURCE}).dataSource("/Myxml/Data[Foo != '']")

 

NOTE the Xpath, this needs to point at your data.

 

2) the subreport expression. ie

 

"MySubreport.jasper"

 

This is the name of the compiled jasper subreport.

 

luck

I use the wizard.

 

to 1)

 

The connection is the same like parentreport ( "$P{REPORT_CONNECTION}" ) .

 

The XPath from subreport is "/root/ATOS/Measure". It is valid, because as alone report it works fine, only not as a subreport.

 

To 2) The subreportexpression is valid to, i've selected from File-Browser and in all other cases it works.("mv_atos_part.jasper") I don't know whats the Problem....

 

:blush:

Maybe it is a general bug?

 

I had create a simple report with a simple XML-file as datasource and a parentreport where this report was insert and there was the same problem...the parentreport use the same data source, too:S

[gombs]

I think it is a generally JR problem, I've tested to fill in a java-app and get the same error.

 

 

Nobody has the same problem?

[fero2]

Hi, I have the same problem. But I am curious if somebody have the solution.

[fero2]

I solved it. In subreport properties. U need to choose "Use data source expression". And then put inside $P{REPORT_DATA_SOURCE} or what ever u want. When u choose "Use connection expression" it is not working.

[gombs]

Hi, I became a solution from iReport Master:

 

a Expression like this:

 

((net.sf.jasperreports.engine.data.JRXmlDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("/root/Measure"))

 

will work, too B)

[gombs]

Ok in iReport it works fine.

But in a java app I get following error:

 

Error evaluating expression :

Source text : ((net.sf.jasperreports.engine.data.JRXmlDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("/root/ARGUS")

 

What is wrong?

Could you please post your jasper report file?
