How do I use JMQ from a servlet?

I need to satisfy the following requirements. Please follow the sequence (I dont have Rational Rose with me! :-))
1.A end user sends a web request (for a servlet) through the browser.
2.Servlet sends a message to a backend process via JMS.
3.backend process does something and creates display data for the servlet.
4.backend process sends a message containing this data back to the servlet via JMS.
The stringent requirements are that step 2 and 4 have to be achieved using JMS. This is not negotiable! :-) Based on my limited knowledge of JMS, the way to achieve this is by
1.Having a Destination (Queue/Topic) for which the backend process is the consumer and all servlet instances are producers.
2.Or every request that the servlet receives, create a TemporaryQueue and send its name to the backend process through the message sent by the servlet. The servlet is the consumer of this queue and the backend process becomes the producer to send the display data to the servlet.
Is anybody knowledgable enough in JMS, to tell me if this is likely to fail? Or if there is a better solution?

Sounds reasonable to me. Take a look at the JMS javadoc for TopicRequestor
or QueueRequestor. Same idea. The client receiving the first message gets
the reply destination from the ReplyTo field in the incomming message.

How can I use music from two different iTunes accounts?

how can I use music from two different iTunes accounts?

If you mean iTunes Store accounts, there's really nothing for you to do. Just add the tracks to the iTunes library and play them. Music purchased prior to late-2009 will been to be authorized, though. Pull down Store > Authorize... and type the credentials of the Apple ID used to buy the tracks.
If you mean something else, please describe in more detail.

Thanks in advance

Sweep is correct about requestDispatcher being another approach for inter-servlet delegation; the only issue that i recall with this approach is that it defaults the method of the destination servlet to the one it was called from...for example, calling servlet2 from within servlet1.post() resulted in the dispatcher attempting to utilize servlet2.post() - i believe that i searched for a parameterize solution to no avail :( (ended up handling the request by placing a "fake" doPost() in servlet2 that simply called servlet2.doGet())
however, if your application is functioning correctly on your pc/webserver then the problem may be external to servlet communication (e.g. client webserver's ports not configured or blocked, missing runtime classes, etc.)
my suggestion would be to set aside the programmatic concerns for the moment - what is the response if you open a browser on a client's machine and access the URL in question (i.e. http://clientserver:port/stefanoServlet)? If it will not respond to access in this manner then it certainly won't when your application calls for it.
It's possible that there is a coding error but, given the info supplied, i'd start examining the environment, first. Let us know if you have any luck with the test i recommended or not (please provide abundant detail). Or, if you've found the solution then you may want to post back with a quick blub so the next person knows how to escape the trap.

How to pass a string from a servlet to client side

hi,
i would like to generate a string from a servlet and pass it to the client side. the client will receive the string by using request.getParameter(). How should i implement this system? Could anybody give me some hint?
Best Regards,
Henry

Greetings,
hi,
i would like to generate a string from a servlet and
pass it to the client side. the client will receive
the string by using request.getParameter(). HowAre you referring to the instance of (Http)ServletRequest the 'request' object being passed to the "client"? What is the "client" in this case? If you mean a "traditional" client communicating over (or by tunneling through...) HTTP then no can do. The (Http)ServletRequest object is generated by the web container (a.k.a. "servlet engine"), not by the client, and it is not serializable so there is no way to pass it back to the client...
should i implement this system? Could anybody give me
some hint?It depends again on "what is the 'client' in this case?"

How to implement use bean tag in servlet technology

The application scope corresponds to the servlet context. From your servlet, use getServletContext().getAttribute() and getServletContext().setAttribute().

How to pass submitted Data from a servlet to EJB Session Bean in JPA

How to pass Data User submitted Data from a servlet to EJB Session Bean when using JPA :
Hi ,
I have a jsp page in which the user fills up the Data and submits it to the servlet :
Inside servlets i am getting all the parameters and setting it to the Entity Class .
Sample Entity class is shown below :
@Entity
public class Employee {
@Id private int id;
private String name;
public Employee() {}
public Employee(int id) { this.id = id; }
public int getId() { return id; }
public void setId(int id) { this.id = id; }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
}After calling setters of my Entity Class .
I am using JNDI lookup to call my session Bean method and pass this Entity class to the session Bean to persist data
Please let me know what will be the right approach :
1. Passing parameters whole as a Entity Class
that is
public void insertData(Employee emp)
}Or
2. public void insertData(String Name , int ID)
}

they are both right as they both work. Easy huh?
You might argue that if you have to set a lot of fields, use the entity as otherwise you get a method with a gigantic amount of parameters.

Using data from a servlet

How do you launch browser from a servlet

I have an interesting issue here. I send data to a servlet and the servlet recieves and processes the data (confirmed through breakpoints) but I want to display the data in a JSP or directly thru the servlet using html tags.
However I can forward or redirect the data from the servlet to my jsp code but this still doesn't launch a browser.
A little more detail... I am not sending information from a JSP to the servlet. The servlet is listening on a port for input, so the servlet is being invoked directly when the data comes in. In the current state my servlet sends the results in a session object to a JSP which gets the results but can't display them since it doesn't launch browser.
Does anybody know how to display my calculated results from the servlet in a browser?

Ok let me try to be more specific. I have an application that sends data to the servlet over a socket connection. The servlet gets this data and multiplies it by a factor.
When I put break points in, I see that the servlet gets this data.
Now I am trying to display the data in a browser.
Upon entry to doGet the servlet checks if the String variable that gets the parameter is not null. If it is not null then it forwards to a JSP.
But I tried a scenario where I have a browser open that has the localhost address of the servlet and then I run the program which is outside the war file that contains the servlet to send data to the servlet, but when the servlet gets the data, it does the forward to the JSP but the page is not displayed. However I see the process move to the JSP thru the break points I put in.
I know its kind of a weird scenario but I suspect that since the program calls the servlet and it gets the data, it must need to launch a new browser in order to be able to display the JSP it forwarded to.
I could be wrong but so far I have exhausted all possible ideas in my head for now so if you understand what I am saying perhaps you can tell me if you know a better way to do this...
Thanks

How to Call SQL Loader from Java ( servlet )?

We need to call SQL Loader command from Java Servlets? Any suggestions how this can be done?

Probably not the best way, but you could try using JNI to call a C function which then invokes SQL Loader via system() or exec(). I haven't done this myself though...

How to get useful data from request?

Hello.
I am looking for creating a management tool for a web site. All I want is that is there any ready to use API or package or open source project for retrieving user�s information? I just mean that is there any easy to use way in java to get useful data from a client (for example location, his or her system configuration and information �).
Thanks.

If you dump all the data from request (see the javadoc, and especially the "header methods" ) you'll see the data you can get are quite simple.
The only thing you can try to rely on are ;
- the IP address from the sender (when reversed to DNS, you can sometime use the tld to locate the country it comes from. Yet, you'll get many .com name, so it's not that significant. it may also give you the IAP used). Note that if the user is using a proxy, it's the proxy IP that you'll collect
- the User-Agent header : from this, you can guess the OS and the browser used
- the Referer header : usefull to get where your user comes from (where they found a link to your site)
- the Cookie header : if you're using a servlet container with session id stored in cookie, you should see the Cookie header appear on the second request to your site. That helps finding out wether your user accep cookie or not (from a server point).
Besides these, i don't think you can get any other useful data without asking your users on a form. Note that it's the client that decides to send Referer, User-Agent or Cookie headers. Those are not mandatory to the Http Protocole and some browser allow their user to fool their content (butmore than 90% of the widespread browsers don't)
