Hey darelatlexon,

As jawwadfarooq1 said earlier, its better to have compiled report files in your workspace and also if report data is huge Virtualizer.

RE:Strange exception on JasperFillManager.fillReport()

Fri, 10 Feb 2012 08:02:23 +0000

Hi,

From the error I guess the problem is with your Xml Data Source.

Why do you use a .tmp file? Shouldn't it be an xml file? It seems that the loaded document is null:

The supplied org.w3c.dom.Document object is null: If you check the javadoc this interface is related to xml files so the problem happens when you try to load the tempfile.tmp file.

Don't know if JRXmlDataSource supports another kind of file but I think it should be an xml file.

Hope this helps.

Regards.

RE:An error has occurred. (6632) - SQL validation of stored procedure in 4.5 breaks all report queries?

Thu, 09 Feb 2012 17:09:36 +0000

We experienced this issue too. Our DB that we query against is SQL server, and the workaround was simple (but should not be needed). We changed our stored procedure into a table-based function and can now do:

select * from (,)

Hope this helps you too.

Hey norhidayah,

you need to keep all the jar files in you classpath. Set those classpath setting in your IDE.

Thanks,

RE:How to query xmlns= with XPath ?

Thu, 09 Feb 2012 09:53:53 +0000

According to the Xalan mainling list (http://old.nabble.com/XPath-with-default-namespace---No-result-tt33285727.html#a33285727) this behavior is expected. I understand why, and are different elements and should be accessed in two distinct ways.

The solution I see would then be to provide a PrefixResolver as explained here : http://www.edankert.com/defaultnamespaces.html. I can do this by providing a different XalanXPathExecuterFactory that would have a PrefixResolved as attempted in that page http://jasperforge.org/plugins/espforum/view.php?group_id=102&forumid=103&topicid=44911.

The issue for me now is to be able to initialize the resolver with the XML input. At the moment I could just hardcode prefix / namespace mappings in the getNamespaceForPrefix(String prefix) which seems to be used over getNamespaceForPrefix(String prefix, org.w3c.dom.Node namespaceContext).

JAXPPrefixResolver (http://www.docjar.com/html/api/com/sun/org/apache/xpath/internal/jaxp/JAXPPrefixResolver.java.html) does that kind of parsing but needs a namespaceContext at initialization, which is not provided by the Factory.

RE:[LineChart] x-axis labels : show only one of two

Tue, 07 Feb 2012 15:04:34 +0000

Great !!

I just have a bug when trying to edit timePeriod through jasper interface (it automatically put "year" as value, and impossible to modify it), but by editing directly the XML file, it works!

Thank you for your help :)

RE:[LineChart] x-axis labels : show only one of two

Tue, 07 Feb 2012 12:22:54 +0000

Hi.

It was a long ago, my code has changed quite a lot since then and I don't remember everything I did at that time.

But here are some ideas:
- Are you using the last version of jasperreport and its dependencies?

- In a JRChartCustomizer (JFreechart is used here, and its documentation helps):

XYPlot xyplot = chart.getXYPlot();

/* My labels are now displayed vertically with that code: */
DateAxis domainAxis = (DateAxis)xyplot.getDomainAxis();
domainAxis.setVerticalTickLabels(true);

/* And this code can help to choose ticks positions: */
domainAxis.setTickUnit(new DateTickUnit(DateTickUnit.DAY, 7));

- In a jrxml, try changing the timePeriod attribute of the timeSeriesDataset tag:

where xxx can be Year, Quarter, Month, Week, Day, Hour, Minute, Second, Millisecond

Good luck
