Hello,
I am trying to create an application for the mobile phone from which you can
download a Java ME application.
I have gotten so far that I can download the .jad file but the only thing that
happens is that the content it is presented on the screen like this:
MIDlet-1: WLListenerMIDlet,,WLListenerMIDlet
MIDlet-Jar-Size: 44641
MIDlet-Jar-URL: MobileTrainer.jar
MIDlet-Name: MobileTrainer
MIDlet-Vendor: Vendor
MIDlet-Version: 1.0
MicroEdition-Configuration: CLDC-1.1
MicroEdition-Profile: MIDP-2.1
I.e, the actual application (.jar) is not downloaded.
The URL when this is presented is ending with "downloadMobileTrainer.action",
i.e. not the actual file. When accessing the .jad file directly it works.
I am in a need of help because I am stuck and are getting no further. I also
wonder if this is the correct way of doing it, if it is possible at all
using StreamResult for my purpose. I would really like to use Struts2 built in
feature for this if possible.
Here is my code:
My download form in the jsp page:
struts.xml:
text/vnd.sun.j2me.app-descriptor
../../jsp/mobile/error.jsp
Extended StreamResult class:
public class DownloadInterceptor extends StreamResult{
protected void doExecute(String finalLocation,
ActionInvocation invocation)
throws Exception {
String downloadedFileName = "MobileTraining.jad";
contentDisposition = "filename=\"MobileTraining.jad";
contentLength = ""+
invocation.getStack().findValue(conditionalParse("size", invocation));
// contentType = "text/vnd.sun.j2me.app-descriptor";
super.doExecute(finalLocation, invocation);
}
}
My action class:
public class DownloadMTAction extends ActionSupport {
private File mobileTrainer;
private String contentType;
private String filename;
private InputStream inputStream;
public InputStream getInputStream()
{
try{
inputStream = new FileInputStream(new
File("C:\\\\Users\\Niklas\\Documents\\JavaMESDKProjects\\MobileTrainer\\dist\\MobileTrainer.jad"));
}catch(Exception e){
System.out.println("Error in DownladMTAction " +
e.getMessage());
e.printStackTrace();
}return inputStream;
}
public void setInputStream(InputStream inputStream){
this.inputStream = inputStream;
}
public void setMobileTrainer(File mobileTrainer) {
this.mobileTrainer = mobileTrainer;
}
public void setMobileTrainerContentType(String contentType) {
this.contentType = contentType;
}
public void setMobileTrainerFileName(String filename) {
this.filename = filename;
}
public String execute() {
this.inputStream = getInputStream();
if(inputStream !=null)
{
return Action.SUCCESS;
}
else
{
return Action.ERROR;
}
}
}
I have tried to set the content-type in both my struts.xml file and the
extended StreamResult class above (now commented out there).
Thank you in advance!
Regards,
Niklas
