Hi Lucian, Thanks for ur reply. I am compiling jrxml file through ant command it does not give any stack trace its just saying net.sf.jasperreports.engine.JRRuntimeException: Error creating SAX parsser at the particular line in build.xml: . and my class path includes the following jars .. commons-beanutils-1.7.jar commons-collections-3.2.1.jar commons-digester-1.7.jar commons-logging-1.1.jar jasperreports-3.5.1.jar jdt-compiler-3.1.1.jar xalan.jar xercesImpl.jar xml-apis.jar poi-3.2-FINAL-20081019.jar jxl.jar ant.jar please suggest any other jars need to be included in the class path. find the attached jrxml sample report created using iReport-nb-3.5.1 ireporttool.(As the requirement changed,we need to upgrade from iReport2.0.1 to iReport 3.5.1) I tried to compile both in JDL1.4 and JDK1.6.Its not getting compiled in both the environments.please help us to resolve the above issue. The below code we are using for compiling JRXML. Code:<!-- Classpath for JasperReports ANT task --> <path id="jr_classpath"> <fileset dir="${project.lib}"> <include name="**/*.jar" /> </fileset> </path> <!-- Defines the ANT task for compiling JRXML files --> <taskdef name="jrc" classname="net.sf.jasperreports.ant.JRAntCompileTask"> <classpath refid="jr_classpath" /> </taskdef> <!-- Compiles the JRXML files into Jasper files --> <target name="compileJRXML" description="Compiles all the jrxml files under the report folder to the sns reports folder"> <mkdir dir="/TestReport" /> <jrc compiler="net.sf.jasperreports.engine.design.JRJavacCompiler" xmlvalidation="false"> <src> <fileset dir="/TestReport"> <include name="**/*.jrxml" /> </fileset> </src> <classpath refid="jr_classpath" /> </jrc> </target>

Hi, We need to upgrade JasperReports developed in iReport2.0.1 to iReport 3.0.0 report designer. I updated all of our JRXML files by loading and saving in iReport 3.0.0 to use the new format. When I compile reports using ant (apache-ant-1.7.0) compiler="net.sf.jasperreports.engine.design.JRJavacCompiler" by setting xmlvalidation to "false" I get the following exception: net.sf.jasperreports.engine.JRRuntimeException: Error creating SAX parser. kindly suggest to resolve the above isuue

Hi, Getting "Error Loading Object from file" while calling loadObject method from JRLaoder class with jasperreports-3.5.1.jar in the classpath .As per the below code snippet. JasperReport jasperReport = (JasperReport)JRLoader.loadObject(sourceFile); Please note that the reports are developed with iReport-2.0.1 jasper report design tool.and the application works fine with jasperreports-1.0.0.jar in the classpath. Do we need to redevelope the reports with the latest iReport design software? Any suggestions would be greatly appreciated. Post Edited by poornima at 05/11/2010 10:52
