Compiling error with in java of IReport jrxml

[danthehorn]

Frustrated!

 

I have solved many issues trying to use Jasper by reading the forums or searching google but this one I don't know what is going on.

 

I take an IReport jrxml that compiles and then try to compile it using the java functions with zero luck. Why do I take an uncompiled JRXML IReport file?

 

That is because I need to create my own JRXML at runtime and thought maybe my JRXML was the issue. Well that did not prove to be the problem.

 

Note:

 

generatedJRXML and generatedPDF are variables that point to the files that must be produced. In this case generatedJRXML points to the valid (ONE FIELD REPORT) created by IReport.

 

code fragment:

 

private void generatePDF() throws Exception {

try {

File xml = new File(generatedJRXML);

JasperDesign jasperDesign = JRXmlLoader.load(xml);

JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);

Map parameters = new HashMap();

Connection conn = DatabaseConnectionManager.getConnection();

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,

parameters, conn);

OutputStream output=new FileOutputStream(new File(generatedPDF));

JasperExportManager.exportReportToPdfStream(jasperPrint, output);

conn.close();

// JasperViewer.viewReport(jasperPrint);

} catch (Exception e) {

ReportError.toUser("Unable to gererate PDF", e);

throw e;

}

}

 

 

Exception:

Solved by dumping the JasperCompilerManager and replacing it with JRJdtCompiler class.

 

.

Method:

.

 

 

 

private void generatePDF() throws Exception {

try {

File xml = new File(generatedJRXML);

JasperDesign jasperDesign = JRXmlLoader.load(xml);

 

 

JRJdtCompiler compiler = new JRJdtCompiler();

JasperReport jasperReport = compiler.compileReport(jasperDesign);

 

// dump it JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);

 

Map parameters = new HashMap();

 

Connection conn = DatabaseConnectionManager.getConnection();

 

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,

parameters, conn);

 

OutputStream output=new FileOutputStream(new File(generatedPDF));

 

JasperExportManager.exportReportToPdfStream(jasperPrint, output);

 

conn.close();

// JasperViewer.viewReport(jasperPrint);

} catch (Exception e) {

ReportError.toUser("Unable to gererate PDF", e);

throw e;

}

}

If it compile with maven, check if maven runner jre is to JAVA_HOME
