O servidor da minha aplicacao era windows e funcionava os relatorios gerados com ireports sem problema algum. Mais depois que passei o tomcat para o linux e os modulos de relatorios pararam de funcionar.
Antes eu usava os comandos com o seguinte caminho
.
.
.
JasperFillManager.fillReportToFile("C:/Arquivos de programas/Apache Software Foundation/Tomcat 5.5/webapps/logistica/relatorios/clientes.jasper", parameters, jrRS );
// Exporta para o formato PDF
JasperExportManager.exportReportToHtmlFile( "C:/Arquivos de programas/Apache Software Foundation/Tomcat 5.5/webapps/logistica/relatorios/clientes.jrprint" );
JasperExportManager.exportReportToPdfFile( "C:/Arquivos de programas/Apache Software Foundation/Tomcat 5.5/webapps/logistica/relatorios/clientes.jrprint" );
JasperViewer.viewReport("C:/Arquivos de programas/Apache Software Foundation/Tomcat 5.5/webapps/logistica/relatorios/clientes.jrprint", false);
.
.
.
e funcionava belezinha, mais agora no linux o que vou colocar no lugar de “C:/Arquivos de programas/Apache Software Foundation/Tomcat 5.5/webapps/logistica/relatorios/clientes.jrprint” por exemplo.
o tomcat ta instalado no /usr/loca/apache-tomcat-5.5.17
o projeto e /usr/local/apache-tomcat-5.5.17/webapps/logistica
e os relatorios tao em /usr/local/apache-tomcat-5.5.17/webapps/logistica/relatorios
ja tentei varias formas e
quando eu mando gerar o relatorio aparece:
