[Sulaiman Malik]

I am having the problem with jasper report 3.7.2 and using in Oracle JDeveloper 11g. I made the report in IReport 3.7.2 and calling it from by writing the java code in Oracle JDeveloper 11g. and i am getting an exception when i run it from Oracle JDeveloper 11g. I need an urgent help on this exception may be i am missing some Jar Files or not using the rite jar files. The exception is given below. You can see the bold ones, the rest are the details of the exception

I need an urgent help....

[Martijn Verburg]

Looks like it's trying to load an HTML document, is this the behaviour you're expecting?

[David Newton]

Agreed--are you feeding it a valid report XML file?

[Sulaiman Malik]

@Martijn Verburg...Yeah, i am exporting it to Html File.

[Sulaiman Malik]

@David Newton, yeah i am feeding a correct XML, i made the sample report through wizard and calling that report from a java code written in Oracle JDevelopr 11g

[David Newton]

I don't believe you :) Jasper is trying to load a file with HTML in it:

 net.sf.jasperreports.engine.JRException: org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'html'.
at net.sf.jasperreports.engine.xml.JRXmlLoader.loadXML(JRXmlLoader.java:245)
at net.sf.jasperreports.engine.xml.JRXmlLoader.loadXML(JRXmlLoader.java:228)
at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:216)

at net.sf.jasperreports.engine.JasperManager.loadXmlDesign(JasperManager.java:967)
at jsp_servlet._fas.__samplereport._jspService(__samplereport.java:83) 

So perhaps post the relevant portions of the JSP (this should be done in Java, not in a JSP) that is creating the report.

[Sulaiman Malik]

@David Newton... i am writing the java code in a jsp file by using the scriplets....

<%@ page import="net.sf.jasperreports.engine.*,net.sf.jasperreports.engine.design.JasperDesign,net.sf.jasperreports.engine.xml.JRXmlLoader"%>
<%    
  JasperReport jasperReport;
  JasperPrint  jasperPrint;
  JasperDesign jasperdesign;
  
  jasperdesign = JasperManager.loadXmlDesign(getServletConfig().getServletContext().getRealPath("/reports/report1.jrxml"));
  jasperReport = JasperCompileManager.compileReport(jasperdesign);            
  jasperPrint = JasperFillManager.fillReport(jasperReport,null);
  JasperExportManager.exportReportToHtmlFile(jasperPrint,getServletConfig().getServletContext().getRealPath("/reports/report1.jrxml"));
%>

well i will try this out also by making a java file and write the code in java file.

[David Newton]

Ah, that explains it. Look at the Javadocs for JasperExportManager:

exportReportToHtmlFile(JasperPrint, String)
exportReportToHtmlFile(String, String)
exportReportToHtmlFile(String)

And hope you have a backup. And trust us, and the exception message, when we all say the same thing :)

[Sulaiman Malik]

@David Newton...ok David i will look at the java docs and will let you know for this.

[Sulaiman Malik]

@David Newton....i have also made the java file but still an exception.....one thing more it is not compiling the report, it throws the exception during the compilation of the report so one thing is for sure that it is not compiling the report

[David Newton]

Come on: pay attention to what you're doing. *Look* at the documentation; I provided links. Destination file... *destination* file. You're right, it's *not* compiling the report, and two people and the documentation have told you why not.

String path = getServletConfig().getServletContext().getRealPath("/reports/report1.jrxml";
jasperdesign = JasperManager.loadXmlDesign(path);  
JasperExportManager.exportReportToHtmlFile(jasperPrint, path);  

Now do you see?

[Sulaiman Malik]

@David Newton...its done i have missed a little point now its done...thnx a lot

[David Newton]

No problem--glad you figured it out :) Seeing stuff like that can be tricky sometimes, especially when things aren't refactored and easy to read. Almost any time I see any repeated code I try to eliminate it, making this kind of error more difficult to make.

[Sulaiman Malik]

@David Newton...yeah you are right, there is always a little problem left which is a little difficult to figured it out...I was stuck in this problem from the last 2 days,but i am glad now it is solved out...so much thanks David. Will be looking forward for more help from you if any needed.
