Pessoal,

Qual são os requisitos para o bom funcionamento do plugin vraptor-jasperreport?

Estou tentando rodar em um Wildfly 9, Java 1.8 e Vraptor 4.2.0-RC3.

Ao tentar rodar o plugin não consegue achar o path do contexto e estoura o erro:

O null acontece no ReportPathResolver.java.

Oi Pablo

Esse é um plugin de usuário, não somos nós que mantemos, então não saberia dizer ao certo os requisitos. Mas olhando o código não parece depender de nada específico de alguma versão mais nova do VRaptor.

A exception não mostra mais nada relevante?

Se quiser investigar mais a fundo, experimenta baixar o código do plugin e debugar local. Ou talvez atualizar as dependências dele e ver se acontece algum erro de compilação e o mesmo problema de execução.

Então Turini,

Debugando eu percebi que acontece um erro que não sei o motivo de estar acontecendo: ele não acha o path do contexto. A meu ver, e pelo que até o momento pesquisei, está tudo certo com a implementação:

@ApplicationScoped

public class ReportPathResolver {

@Inject private ServletContext context;

private String getRelativeReportsPath(){

String param = context.getInitParameter("vraptor.reports.path");

return param != null ? param.trim() : DEFAULT_REPORTS_PATH;

}

public String getReportsPath(){

return context.getRealPath(getRelativeReportsPath()) + SEPARATOR; //aqui ele retorna null na saída do getRealPath()

}

Pablo, nunca usei o plugin, mas pelos erros, parece que o parâmetro

vraptor.reports.path

não está definido, gerando o erro

Caused by: net.sf.jasperreports.engine.JRException: java.io.FileNotFoundException: null\teste.jasper

Att,

Cleber.

Cleber,

Obrigado pela resposta. Mas o problema não está ai. E sim na chamada do context.getRealPath();

Na verdade existe um problema relacionado ao container. Em teoria esse código funcionaria em um Tomcat. Segundo a documentação de especificação do Servlet:

"In situations where the servlet container cannot determine a valid file path for these
methods, such as when the Web application is executed from an archive, on a remote
file system not accessible locally, or in a database, these methods must return null.
Resources inside the META-INF/resources directory of JAR file must be considered
only if the container has unpacked them from their containing JAR file when a call to
getRealPath() is made, and in this case MUST return the unpacked location."

Baseado nisso o que eu fiz foi pegar o ServletRequest a partir do HttpServletRequest:

@ApplicationScoped

public class ReportPathResolver {

@Inject private ServletContext context;

@Inject private HttpServletRequest request;

public String getReportsPath(){

ServletContext myContext = request.getSession().getServletContext();

return myContext.getRealPath(getRelativeReportsPath()) + SEPARATOR;

}

O resultado disso foi:

'C:\e2pd\audmob\web\ambiente\wildfly-9.0.2.Final\standalone\deployments\audmob.war\audmob\src\main\webapp\WEB-INF\reports\teste.jasper"

Mas ai me deparei com outro problema, quando o plugin chama o JRLoader.loadObjectFromFile(template) ( onde template é o endereço que eu copiei acima) ele dá erro novamente:

21:58:29,868 ERROR [io.undertow.request] (default task-2) UT005023: Exception handling request to /audmob/relatorios/teste/pdf: br.com.caelum.vraptor.InterceptionException: java.lang.RuntimeException: net.sf.jasperreports.engine.JRException: java.io.FileNotFoundException: C:\e2pd\audmob\web\ambiente\wildfly-9.0.2.Final\standalone\deployments\audmob.war\audmob\src\main\webapp\WEB-INF\reports\teste.jasper
