problem while compiling jrxml

[tekin]

Hi,

I am the chief programmer of German Hospital in Istanbul.

We are now preparing an application component to produce executive reports. Some 4 years ago we have worked on a similar project and haven't had no problems at all.

We prepare report designs with iReports, plan is to keep the xml's on server, compile them as necessary, fill the reports at the server-side and send them off to the requester.

The problem we are having is that we get a java.lang.reflect.InvocationTargetException in JRXmlLoader class at loadXML() method. The exception is thrown when the loader requests digester to parse the file.

I traced the exception to apache commons-digester Digester class's getXMLReader() method and found a note from the developer stating: "there is a bug in JAXP/XERCES that prevent the use of a parser that contains a schema with a DTD".

I wonder if there's a cure for this? Or else is there any alternative method to compile report designs?

Best regards,

Cem.

Could you post the full exception stacktrace and more information about this?  Ideally, the information should be sufficient to reproduce the problem..

Hi,

There is problem while compiling jrxml with Jasperreports 3.5.1.

For example, I use jasperreports-3.5.1-project.zip, try to run sampls\templates, and give command ant compile, get exception,

 

 

 

Code:

I personally have no problem with this report, everything goes smoothly in my case...

[andfedotov]

Well, at first let's unite 2 discussion threads (on of them on Project Tracker) cause it's starting going a bit messy

Hongwei, I have no problem with compiling this report.
Looks like it's something wrong with the jrxml file itself (XML Parser complains on DOCTYPE). Have you ever edited it?..
Try the original file - it should be ok

I have also no problem with compiling jrxml using jasperreports-2.0.4.jar, which uses jaspereports.dtd.
but using jasperreports-3.5.1.jar, which uses jasperreports.xsd have problem.
for example, in file samples/templates/Styles.jrxml, which uses xml schema jasperreports.xsd, the root element is:
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" [^]
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" [^]
        xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports [^] http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" [^]
        name="Styles" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="30" bottomMargin="30" whenNoDataType="AllSectionsNoDetail">
...
</jasperReport>

so it does not work.

My thought is that you might have some problems with classpath..

Make sure jasperreports-3.5.1.jar or compiled classes dir is in your classpath and no previous versions of jasperreports is overwriting this...
