Question

I was ok to define it in struts.xml config.

<action name="getImage" class="my.action.GetImageAction">
      <result name="success" type="stream">  
          <param name="contentType">image/jpeg</param>  
          <param name="inputName">imageStream</param>  
          <param name="bufferSize">1024</param>  
      </result>  
</action>

And I am now trying to define it by annotation on the class with namesapce, result path, and I have no idea how to do it. Please help 🙂

I have tried

@Namespace("/my/namespace")
@ResultPath("/")
@Result(name = "success", type = "imageResult")
public class GetImageAction extends ActionSupport {
.....
@Override
@Action("/getImage")
public String execute() throws Exception {
.....

And I got an error

HTTP Status 404 - No result defined for action 

Answer 1

As the error says the results have to be defined at the Action.
The definition would look like this

@Action(value = "getImage", results = { @Result(
        name = "success", 
        type = "stream", 
        params = {"contentType", "application/pdf" }) })

In the example you see the type too and how to define the contentType.

And the stream will be returned by the “getFileInputStream”-method:

public InputStream getFileInputStream() {

            return fileInputStream;
    }

the “getContentDisposition”-Method has to be available in the Action-class

public String getContentDisposition() {
    return "attachment; filename=" + getFilename() + ".pdf";
}
