Why do you work on DataRows ... DataObjects are much more like BusinessObjects.
If you work on DataObjects and there are some getters for transient informations coming from business-logic it can help a lot. Just one more hint: reading content of DataObjects with jxpath is really cool. 2006/5/11, Alan Baltazar <[EMAIL PROTECTED]>:
hello, i implemented this http://www.objectstyle.org/confluence/display/CAY/Jasper+Integration to integrate cayenne and jasperreports for a web application (no spring framework, just straight cayenne,struts web app). my problem here, is that, I get a class cast exception for this class, DataRowDataSource (see arrow below). public class DataRowDataSource implements JRDataSource { private Iterator rowIterator; private DataRow activeRow; public DataRowDataSource(List dataRowList) { rowIterator = dataRowList.iterator(); activeRow = (DataRow)rowIterator.next(); <--- cast problem here (posted sample didn't have the (DataRow) cast, i added it here to compile) } public boolean next() throws JRException { boolean hasNext = rowIterator.hasNext(); if (hasNext) { activeRow = (DataRow) rowIterator.next(); } return hasNext; } public Object getFieldValue(JRField field) throws JRException { return activeRow.get(field.getName()); } } has anyone implemented this sample? if yes, how did you fix this problem? I'm using the latest cayenne, struts, jasperreports versions. Alan,
