"IllegalStateException: Response already committed" in Struts2 Interceptor chain on WebLogic 10.3.x on Linux [duplicate]

I have some code for download file from web server.
Everything works alright, but in console I have this exception:
июн 26, 2015 2:08:42 AM org.apache.catalina.core.StandardWrapperValve invoke

Why and what it can be? And how i can fix this problem? I try find answer in the google, but I failed.
The code:
package actions;
import java.io.IOException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServletResponse;
import javax.xml.ws.Action;
import org.apache.log4j.Logger;
import org.apache.struts.chain.contexts.ServletActionContext;
import service.CsvCreator;
import com.opensymphony.xwork2.ActionSupport;
public class DownloadCsvAction extends ActionSupport {
private static final long serialVersionUID = -4714537109287679996L;
private CsvCreator CSVcreator;
private static final Logger logger = Logger.getLogger(DownloadCsvAction.class);
public CsvCreator getCSVcreator() {
return CSVcreator;
}
public void setCSVcreator(CsvCreator cSVcreator) {
CSVcreator = cSVcreator;
}
#Override
public String execute() {
HttpServletResponse response = org.apache.struts2.ServletActionContext.getResponse();
response.setHeader("Content-Disposition", "attachment; filename=\"phone_records.csv\"");
response.setContentType("text/csv");
ServletOutputStream out;
try {
out = response.getOutputStream();
String tableHeader = "Caller, Event, Reciever, Timestamp\n";
out.write(tableHeader.getBytes("UTF-8"));
out.write(CSVcreator.getAllRecordsInString().getBytes("UTF-8"));
out.flush();
out.close();
} catch (IOException e) {
logger.error(e.getMessage());
}
return SUCCESS;
}
}
And my struts.xml:
<action name="DownloadCsvAction" class="DownloadCsvAction">
<result name="success" type="dispatcher"/>
</action>

Why and what it can be?
Because response is already committed. You have closed response before it's used by the Struts2.
And how I can fix this problem?
When your action execution ends, return Action.NONE result code. This code tells the invoker to not execute any result because response might be already committed.
You can also rewrite the action implementation to use stream result type. In this way you have not to do with the response and let Struts2 do the rest. Example of using stream result is here.

why FacesContext.getCurrentInstance().getExternalContext().dispatch(url) throws exception [duplicate]

The page should be rendered only if user has permissions to see it. I try to achieve that by performing a check in PreRenderView event listener method:
<f:event type="preRenderView" listener="#{theBean.init}" />
And the method itself:
public void init() {
if (user.havePermission()) {
// backing bean init
} else {
FacesContext fc = FacesContext.getCurrentInstance();
ExternalContext ec = fc.getExternalContext();
ec.getRequestMap().put("message", no_permissions_message);
try {
ec.dispatch(ec.getRequestContextPath()
+ path_to_no_perm_page);
fc.responseComlete();
} catch (IOException e) {
e.printStackTrace();
}
}
}
When I try to look at denied page I see it, but get an exception in server log:

The cause: immediately after dispatch call, FacesContext.getCurrentInstance() returns null. But this don't interrupt current phase. So on the phase end PhaseListener is executed. It tries to get FacesContext instance, but gets null.
Can I avoid PhaseListener execution here?
Or may be check for FacesContext current instance is not null should be added to omnifaces?
Thanks.

Do not use ExternalContext#dispatch(), ever. This method has no single sensible use case in a decent JSF web application. It only corrupts the JSF life cycle because it creates another FacesContext within the current request. You should use JSF's own NavigationHandler or use ExternalContext#redirect().
When you're already on JSF 2.2, use <f:viewAction action="#{bean.init}"> which supports a navigation case outcome (like <h:commandButton action>):
public String init() {
// ...
return "someViewId";
}
Or when you're still on JSF 2.0/2.1, and can thus only use <f:event type="preRenderView">, and given that you're using OmniFaces use its Faces#navigate() or Faces#redirect():
public void init() {
// ...
Faces.navigate("someViewId");
}
In case you aren't using OmniFaces, here's how it's implemented:
public void init() {
// ...
FacesContext context = FacesContext.getCurrentInstance();
context.getApplication().getNavigationHandler().handleNavigation(context, null, "someViewId");
}
Note that this all may still fail when using #PostConstruct instead of f:viewAction or preRenderView. See also a.o. Redirect in #PostConstruct causes IllegalStateException.

Can't Deserialize JSON in Java Servlet

My endpoint can't make sense of incoming JSON.
Here's the endpoint:
import javax.ws.rs.Consumes;
import javax.ws.rs.DefaultValue;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import org.hibernate.Query;
import org.hibernate.Session;
import org.json.JSONObject;
...
#POST
#Path("/{department}/{team}")
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
public Response handleJSON(JSONObject json , #PathParam("department") String department, #PathParam("team") String team){
MyObj myObj = new MyObj();
myObj.setDepartment(department);
myObj.setTeam(team);
myObj.setPlatform(json.optString("platform"));
saveObj(myObj);
return Response.ok(true).build();
}
I'm posting JSON containing the key/value for "platform" using Postman, with header: Content-Type as application/json
But I get this exception: com.owlike.genson.JsonBindingException: Could not deserialize to type class org.json.JSONObject
Looks like the problem has to do with: Illegal character at row 0 and column 1 expected { but read '-' !
But I'm pretty sure Postman should be sending valid JSON...
Here's more of the stacktrace:

This might not be an ideal solution, but i do think it could work.
Hopefully you have the Jackson JSON dependency already...
you can find it here: http://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-core
I would try the following code:
#POST
#Path("/{department}/{team}")
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
public Response handleJSON(String json, #PathParam("department") String department, #PathParam("team") String team){
ObjectMapper mapper = new ObjectMapper();
JsonNode node = mapper.readValue(json, JsonNode.class);
MyObj myObj = new MyObj();
myObj.setDepartment(department);
myObj.setTeam(team);
if (node.get("platform") != null) {
myObj.setPlatform(node.get("platform").textValue());
}
saveObj(myObj);
return Response.ok(true).build();
}
Notice that I am asking your WS Framework to just pass me the JSON as a String and just handling it myself.
Maybe its not ideal, but should work.
Cheers!

I don't know which JSON Serializer you are using but most probably this will be Jettison or Jackson. As far as I know they don't support converting an instance of org.json.JSONObject directly. The more common way is to simply use custom Java Beans:
public class Foo implements Serializable {
private String platform;
// getters + setters
}
#POST
#Path("/{department}/{team}")
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
public Response handleJson(Foo foo, #PathParam("department") String department, #PathParam("team") String team) {
...
myObj.setPlatform(foo.getPlatform());
...
}
Foo should be annotated with #XmlRootElement if you are using Jettison.
If you don't want to create a custom Bean for every Entity you are expecting you can use Object, Map or String as parameter and serialize on your own:
#POST
#Path("/{department}/{team}")
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
public Response handleJson(String json, #PathParam("department") String department, #PathParam("team") String team) {
...
JSONObject jsonObject = new JSONObject(json);
myObj.setPlatform(json.optString("platform"));
...
}
Last solution is implementing a MessageBodyReader which handles JSONObject. Simple example:
#Provider
public class JsonObjectReader implements MessageBodyReader<JSONObject> {
#Override
public boolean isReadable(Class<?> type, Type genericType, Annotation[] annotations, MediaType mediaType) {
return type == JSONObject.class && MediaType.APPLICATION_JSON_TYPE.equals(mediaType);
}
#Override
public JSONObject readFrom(Class<JSONObject> type, Type genericType,
Annotation[] annotations, MediaType mediaType,
MultivaluedMap<String, String> httpHeaders, InputStream entityStream)
throws IOException, WebApplicationException {
return new JSONObject(IOUtils.toString(entityStream));
}
}

You should first inspect how your request is being sent. It is probably being sent as an escaped String, instead of raw JSON.
In my case, that was what was happening when I was using a generic REST client to send requests as pure JSON Strings, as my client doesn't know the object definitions.
To prevent that, in your client, you could send a (org.codehaus.jettison.json) JSONObject instead of just a String (it has a constructor that accepts a JSON String), but that will depend on your dependencies. In my case I'm using Jersey 1.19.
Note that, depending on your classpath, (Jersey 1.19 with Genson in my case) you might also need to read the response input stream manually if you also want to read the response as a JSON String.

NoSuchMethodError Exception for setEntity in ContainerResponseFilter

I am implementing a JAX-RS filter with CXF and I am trying to edit the Entity of the response. My filter's code is shown below
public void filter(ContainerRequestContext requestContext,
ContainerResponseContext responseContext) throws IOException {
String s = (String) responseContext.getEntity();
responseContext.setEntity(s + "an additional message");
}
The problem is that I am getting an NoSuchMethodError when I am running it.

What am I doing wrong? Is that meaning that the setEntity() method is defined in the API but is not implemented by the CXF Framework?
Thanks

Try implementing a CXF filter instead of direct JAX-RS filter. For that you will have to implement ResponseHandler interface.
Following is dummy code :
package com.question;
import org.apache.cxf.jaxrs.ext.ResponseHandler;
import org.apache.cxf.jaxrs.model.OperationResourceInfo;
import org.apache.cxf.message.Message;
/*
* Filter for Responses
*/
public class CustomOutfilter implements ResponseHandler
{
/*
* #param : arg0
*
* #param : arg1
*
* #param : arg2
*
* #return : Response
*/
#Override
public Response handleResponse(Message arg0, OperationResourceInfo arg1,
Response arg2)
{
//play with arg2 here and return it
return arg2;
}
}
