Hi, I have created a new report in JasperSoft Studio, now I have defined mysql db as source data. When I press preview button, all my fields defined in my sql "SELECT" are show in the manner that I need. But the error now is: " java.lang.ClassCastException: cannot assign instance of net.sf.jasperreports.engine.base.JRBaseStaticText to field net.sf.jasperreports.engine.base.JRBaseParagraph.paragraphContainer of type net.sf.jasperreports.engine.JRParagraphContainer in instance of net.sf.jasperreports.engine.base.JRBaseParagraph" I can't understend what happen, I'm totally lost.

Your last contact you say, seems to be missing pring-beans artifact. I believe that is my problem. when I have created desktop reports using ireports I have defined the path of my bean class. in jaspersoft studio I can't define the path of my bean class. I'm defining the fields by 'add' and 'edit' button in 'java bean' of Dataset and Query Dialog screen. Is right?

After removing org.springframework.beans-3.1.2.release and spring-core-1.0.2 I'm getting java.lang.ClassNotFoundException: org.springframework.beans.factory.support.BeanDefinitionRegistry In my jasperreport I have defined the fields Nome, Sexo, data_Nascimento, telefone_Residencial and these fields are defined in "Dataset and Query Dialog" too. My report is very simple, these fields, title and one field of parameter to receive date.

Hi hozawa, thank you for your assistance. After change the version of jar I'm getting a new error that is: "java.lang.NoClassDefFoundError: org/springframework/beans/factory/support/BeanDefinitionRegistry"

I saw in the internet forums that this problem is some libs out off classpath then I have set up the classpath, below is my libs: jasperreport-6.7.0.jar jasperreport-fonts-6.7.0.jar jasperreport-javaflow-6.7.0.jar this first 3 libs was downloaded from jaspersoft site, "jasperreport library", the next libs was downloaded by search in the internet forums because the ocurred errors. classmate-0.8.0.jar commons-annotations-1.0.0.jar commons-beanutils-1.9.2.jar commons-collections-20040616.jar commons-collections-3.2.1.jar commons-dbcp-1.2.2.jar commons-fileuplod-1.3.jar commons-io-2.4.jar commons-logging-1.2.1.1.jar commons-math-1.0.jar commons-pool-1.6.jar commons-digester3-3.2.jar The last lib was downloaded by http://commons.apache.org/proper/commons-digester/download_digester.cgi how JasperReports Ultimate Guide say, but my problem still the same. Who can help me. Thanks in advance. Cezar Apulchro. My class: public class GeradorDeRelatorios { public void geraPDF(String reportLoc, Map parametros, OutputStream saida) throws JRException { try { JasperReport jasper = JasperCompileManager.compileReport(reportLoc); JasperPrint printR = JasperFillManager.fillReport(jasper, parametros, new JREmptyDataSource()); JRExporter exporter = new JRPdfExporter(); JasperExportManager.exportReportToPdfStream(printR, saida); exporter.exportReport(); } catch(JRException e) { throw new RuntimeException("Erro ao gerar relatório", e); } } } My servlet: protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { botaoacao = request.getParameter("acaobotao"); Map parametros = new HashMap(); if("LstEletro".equals(botaoacao)) { try { PacientesDAO_W01 pcdao = new PacientesDAO_W01(); DadosPaciente dpaciente = new DadosPaciente(); dpaciente = pcdao.lstEletroDia(); sendNome = dpaciente.getNome(); sendSexo = dpaciente.getSexo(); sendDNascimento = dpaciente.getData_Nascimento(); sendTelefone = dpaciente.getTelefone_Residencial(); System.out.println("Nome: " + sendNome); parametros.put("Nome", sendNome); parametros.put("Sexo", sendSexo); parametros.put("data_Nascimento", sendDNascimento); parametros.put("telefone_Residencial", sendTelefone); } catch (Exception e) { e.printStackTrace(); } } ServletContext context = getServletContext(); String reportLoc = "/ITCWEB/ListAgenda_Eletro_W001.jrxml"; GeradorDeRelatorios geraPDF = new GeradorDeRelatorios(); try { geraPDF.geraPDF(reportLoc, parametros, response.getOutputStream()); } catch (JRException ex) { Logger.getLogger(ListAgenda_Eletro_S002.class.getName()).log(Level.SEVERE, null, ex); } }

No news? Cezar.

Hi people, I'm trying to develop reports in java servlet using jasperreports, but I'm totaly lost. I search in internet articles and tutorials to study but can't find. Are there someone that help me by indicating tutorials to study. Thanks alot. Cezar Apulchro.

The problem solved with InputStream exchange by FileInputStream.

I have a problem in my java class when I execute the JasperPrint command and the error is in my InputStream. Because I can´t find de solution to solve this problem, I send this question for you.
