WriterInterceptorContext.proceed - NullPointerException
Hi everybody,
I'm migrating my JavaEE 7 application Glassfish 4.0 to Wildfly 8.1. I configured Wildfly App. Server according to this guide. My project based on maven and it's have some dependencies. (javaee-api-7.0.jar, eclipselink-2.5.1 ect.) This project includes JAX-RS(Jersey) and EJB technologies. And it's works perfect on GlassFish 4.0. I'm not using jersey spesific class or method.
I'm getting NullPointerException in my WriterInterceptor implementation when i proceed context object. My code is something like that.
| Header 1 |
|---|
import java.io.ByteArrayOutputStream; import java.io.FilterOutputStream; import java.io.IOException; import javax.ejb.EJB; import javax.ws.rs.WebApplicationException; import javax.ws.rs.core.MultivaluedMap; import javax.ws.rs.ext.Provider; import javax.ws.rs.ext.WriterInterceptor; import javax.ws.rs.ext.WriterInterceptorContext; import tr.com.emre.core.ejb.log.ServiceAccesLogBean;
@Provider public class ResponseDataWriterInterceptor implements WriterInterceptor {
@EJB ServiceAccesLogBean logBean;
@Override public void aroundWriteTo(WriterInterceptorContext context) throws IOException, WebApplicationException { System.out.println("#DataWriterInterceptor->OK"); final Object requestUidObj = context.getProperty("requestUid");
final MultivaluedMap<String, Object> headers = context.getHeaders(); if (requestUidObj != null) { context.setOutputStream(new FilterOutputStream(context.getOutputStream()) {
final ByteArrayOutputStream baos = new ByteArrayOutputStream();
@Override public void write(int b) throws IOException { baos.write(b); super.write(b); }
@Override public void close() throws IOException { if (requestUidObj != null) { logBean.addResponseDetailToExistingLog(requestUidObj.toString(), headers, baos.toString()); } super.close(); } }); context.proceed(); }else{ if(!context.getPropertyNames().isEmpty()){ for (String name : context.getPropertyNames()) { System.out.println("#Property: " + name); } } System.out.println("#DataWriterInterceptor->Proceed,Before"); context.proceed(); System.out.println("#DataWriterInterceptor->Proceed, After"); } } |
and i'm getting this exception;
