creating report from stream

[greenf]

I want to create report from stream. I take content of jrxml file that works, put it in String, convert it to ByteArrayInputStream and use stream as source of JasperCompileManager.compileReport(). It throws exception with message :

Element bottom reaches outside band area : y=0 height=20 band-height=0

 

Increasing/Decreasing height attribute don't help.

 

Code:

//build string with JasperReport xml inside
      StringBuffer buf =
          new StringBuffer(
                  "<?xml version="1.0"?>n" +
                  "<!DOCTYPE jasperReportn" +
                  "  PUBLIC "-//JasperReports//DTD Report Design//EN"n" +
                  "  "http://jasperreports.sourceforge.net/dtds/jasperreport.dtd">n" );
      buf.append( "<jasperReport name="Simple_Report">n" );
      buf.append( "<detail>n" );
      buf.append( "<band>n" );
      buf.append( "<staticText>n" );
      buf.append( "<reportElement x="180" y="0" width="200" height="50"/>n" );
      buf.append( "<text><![CDATA[Hello word!]]></text>n" );
      buf.append( "</staticText>n" );
      buf.append( "</band>n" );
      buf.append( "</detail>n" );
      buf.append( "</jasperReport>n" );

      //Convert buffer to stream
      byte[] bytes = buf.toString().getBytes();
      InputStream stream = new ByteArrayInputStream( bytes );

      //Convert stream to Jasper Report and JasperReport to PDF
      try {
          jasperReport = JasperCompileManager.compileReport( stream );
          jasperPrint =
                  JasperFillManager.fillReport(
                      jasperReport, new HashMap(), new JREmptyDataSource() );
          //jasperPrint = JRPrintXmlLoader.load( "jasperreports_demo.jrxml" );
          JasperExportManager.exportReportToPdfFile(
                  jasperPrint, "simple_report2.pdf" );
      } catch (JRException e) {
e.printStackTrace();
      }

Excuse for this post. I've have already found a bug. <band> in my Sting don't have height attribute, so it height is 0 and every element will be larget than it.

Probably will be better if administrators will remove this post.
