document.getDatabaseController().setDataSource(dataset,"", "");
and as datasource I used a XMLDataSet

I use the same xml-data and schema as in the .Net environmet.

The reports are designed in Crystal Report Designer and as datasource is an ADO.Net (XML) connection used.

In the old version I use in the .Net-Code a ADO.Net dataset as datasource.

For example
Schemafile:
<?xml version="1.0" standalone="yes"?>
<xs:schema xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
<xs:element msdata:IsDataSet="true" msdata:UseCurrentLocale="true">
<xs:complexType>
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:element name="Parameters">
<xs:complexType>
<xs:sequence>
<xs:element name="DPPROG" type="xs:string" minOccurs="0" />
<xs:element name="DPPANR" type="xs:string" minOccurs="0" />
<xs:element name="DPPAUS" type="xs:string" minOccurs="0" />
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="Header">
<xs:complexType>
<xs:sequence>
<xs:element name="DSFIRM" type="xs:string" minOccurs="0" />
<xs:element name="DSWKNR" type="xs:string" minOccurs="0" />
<xs:element name="DSFIBZ" type="xs:string" minOccurs="0" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:choice>
</xs:complexType>
</xs:element>
</xs:schema>

Data-File

<?xml version="1.0" standalone="yes"?>
<C1PS98>
<Parameters>
<DPPROG>C1PS98</DPPROG>
<DPPANR>*DFT</DPPANR>
<DPPAUS />
</Parameters>
<Header>
<DSFIRM>9</DSFIRM>
<DSWKNR>000</DSWKNR>
<DSFIBZ>DEV-Firma-X (9.000)</DSFIBZ>
</Header>
</C1PS98>

Is there an option to fill the data to the report at runtime in java?

If I would change the datasource in the designer from ADO.NET (XML) to "XML and Webservices". I have the problem, that the used datatables have a different nameing convention. In the report designer I see the following tablenames with the same schema-file.

ADO.NET - Datasource:

XML und Webservices - Datasource:

It is important to reuse or old reports and don't have to redesign each of them, because we have a lot of reports.

Is there a possibility to migrate the report in code? Maybe I can write a .Net or java application to reset the datasources per field. So that I can fill the report in java with datas.

Meanwhile I haven't found a solution yet.

Have anyone a solution or idea for solving my problem?

Thank you for helping.
