Flex with servlets?

how to integrate servlets with flex.. could anyone give some examples of it?

quebequiano,
it all depends if you want your login to be in the Flex part, or simply in a JSP page before you get to the Flex part. Either will do the job, it just depends on your requirements and preference. If you go for a JSP then you can probably tap into the built-in j_security_check functionality and configure your server to check whatever you want, otherwise the route you suggest would be fine. You might want to somehow encrypt the user details before sending them over a plain HTTP link.

Flex with Hibernate using HTTP

Hi All,
am new to Flex. Can any one post a simple code on Flex with
Hibernate using HTTP , i mean connecting to database using
Hibernate and invoking the hibernate by using the HTTP service.
can we have a sequence like
Flex(MXML)->JSP->Hibernate->Database .Is it possible?
Thanks in Advance

> can we have a sequence like
Flex(MXML)->JSP->Hibernate->Database .Is it possible?
That's exactly what you're going to have and it certainly is
possible. (Replace the JSP with Servlet, Struts Action, JSF or
whatever)
Usually you'll send data back -- output to JSP or write to
HttpServletResponse object -- in XML or JSON format. The data would
be delivered to the result event of the HTTService in Flex. If it
fails for some reason, the fault event of HTTService class would be
invoked.
The important thing to realize about Flex is that it cannot
directly connect to a DB; you need a server side action that would
get data from wherever write it to response. It's more like Ajax
calls to a JSP/Servlet.

How to use Flex with EJB3?

Anybody know how to integrate Flex with Java?
I have a EJB3 project with JPA etc...
Have to use Eclipse with Flex plugin or can i use Flex Builder and Eclipse only for java classes? (preferring the second option)
I'm getting crazy, because need this for my college work, too fast as possible.
Please any explanation or sample.
Thanks everyone.

Matt you say, i do not need to write servlet, create wsdl...
But if i dont do this, my Java Business Rules will be visible to client ?
If yes...
1- I need to write Servlet to use HTTP protocol to connect with Flex, then create wsdl of my EJB3.
2- This wsdl will create client side of my application, then i create my Flex interface normally using HTTP Blaze DS ?

Please help me, I need to use Flex with CF

Hi everyone,
I am starting to retract my brain from an intense 2 days to
figure out how to use Flex with Coldfusion. I am using Coldfusion 8
Beta (this part is good, don't need help for CF itself). I am also
using Flex Builder 2 (with chart but this not the topic). I
installed FDS 2.5 before to install ColdFusion 8 but I think CF8
have is own FDS or something like that... anyway, it might help to
mention it!
Well, I tried HTTPService, RemoteObject, WebSer vice -
NOTHING WORKS!!! Argh! Did I mention I spent 2 days? ;-)))
Well, I start with the basic: a login form with an email (as
a username) and a password to be validated. I have a CFC to do the
validation and return a simple message (string): "OK' when it is
valid and a custom message when it is not valid; depending if it is
the password and/or the email which is not valid.
I always got an error. Since the error is different depending
of the method I use, I will explain the latest method I used in
this message and try to concentrate on that method specifically!
The method is WebService and here is the error:
faultCode:Server.Error.Request
faultString:'HTTP request error'
faultDetail: 'Error: [IOErrorEvent type="ioError"
bubbles:false cancelable=false eventPhase=2
text="Error #2032: Stream Error .
URL=http://localhost:8501/iDashboard/login.cfc"].
URL: http://localhost:8501/iDashboard/login.cfc'
Any help will be very useful!!!
Thank's

Cyber,
This may be what you are looking for. It worked well for me.
Flex is sweet, but with the number of people confused about setup
with CF they sure aren't making any friends.

You'd need to put the right stuff in the url to make it work,
just like if
you were calling a page that's expecting GET params. I don't
really use the
HistoryManager, so you'll need to either look into this
yourself or ask
someone who knows more about it.

Flex with Jboss

Hi Friends
I'm developing Flex with java using Blaze-DS under the
Spring MVC. I've problem in using Jboss, Based on BlazeDS
Installation guide
http://opensource.adobe.com/wiki/display/blazeds/Installation+Guide
configure the jboss with Flex.There is no problem with Flex running
in Jboss but it couldn't establish connection and business logic
with java, The Jboss server couldn't through any errors. These same
war file run under the tomcat server. So please help me to solve
this problem.
Thanks&Regrads
Prakasam

I don't have any experience with Spring MVC but I was using
JBoss with Blaze-DS without a problem.
so my next question is, can you make a echo to work??
eg, make a function that returns the input string back to the
flex client.

Using Flex with JSPDynPage

Hi,
Can we develop a JSPDynPage component, using Adobe Flex as the UI instead of using HTMLB? (by embedding flex components in the jsp file). Is it possible to call methods in other java files from a flex application?
Did anyone try to develop a JSPDynPage component this way?

Using Flex with Microsoft Project

I am absolutely brand new to FLEX. What I saw on the Adobe
site was a data chart that could be drilled down to expose
additional layers of "contriburory detail" for the master graph.
What I am wondering is if it is possible to do something
similar using Micrsoft Project Data as the basis. MS Project will
allow users to save the file as XML. So, all the data should be
available in a form understandable to FLEX.
Here's the tricky part (and I can add more detail if needed).
Project will create a summary line (at some level of indentue) and
show you a calculated %Complete such as 47%. So, level of indenture
1 I have the major summary tasks of the project at various status
of %Complete. I believe FLEX can make some type of bar or pie chart
out of that for me. What I want to do is click on a "Level1"
indenture and have it expose the Level2 indure that contributes to
that 47%. Then drill on one of the Level2's to Level3 .... to Level
"n".
This needs to be accomplished in "stand alone" fashion so the
ultimate user can launch a desktop application and tell the
application the name of the Microsoft Project XML file. We will not
be able to use Client/Server ... client side only with the file
located either locally or at least on a network drive.
Can this be done? Has anyone looked at a MS Project XML
schema to see if there is sufficeint information available?
OK, now the blunt truth. It ain't %Complete that I care
about. What I care about is BCWS, BCWP, ACWP, %Complete, and a few
other parameters. These are the "Earned Value Fields". If you do
not know what they are, don't worry about it just now .... it is
really all just time phased data.
Can anyone give me some advice or an opinion? TIA.
Jim

Communicate with servlet after using Java Web Start?

Is it possible to communicate with servlet to get data back and forth
after using Web Start to download the client application?
The demos come with Java Web Start are applications which are
standalone, don't need communicate with the servlet on Web server
after being launched. I am wondering if it is possible, and how (HTTP
& JAX-RPC)?
Thanx in advance.

I've done this using HTTP. I get the server and port from the codebase:
BasicService bs = null;
try {
bs = (BasicService)ServiceManager.lookup("javax.jnlp.BasicService");
String codeBase = bs.getCodeBase().toString();
and use the java.net.HttpURLConnection and java.net.URL classes to send HTTP parameter values to the servlet and to receive results from the HttpURLConnection's input stream.

How to use JNI with Servlets

Hi
i was trying to do some example with JNI. I can use JNI with standalone Java application but I just cannot figure out how I can use JNI with Servlet.
Can some one show me a sample code using JNI with Servlets.
thanks very much

hi,
I am also facing the same problem,
when I am using JNI with stand alone application it works fine but when i tried to use it with a servlet It gives unsatisfied linker error
stack: java.lang.UnsatisfiedLinkError: createSocket
     at RelayConnector.createSocket(Native Method)
     at RelayServlet.doGet(RelayServlet.java:70)

Problem with Servlets

Hi,
I am Tejas , a newbie with servlets. Now, I have a servlet which contains a Javascript method. On clicking a link , the Javascript method is called.
But however, I find that there is some trouble. I created a class called MainFrames.java, the object of which I am instantiating in the Javascript method.
But this code doesnt work properly. I have given the snippet below
out.println("<script type='text/javascript'>");
out.println("function threader()");
out.println("{");
out.println("alert('Inside Threader');");
out.println("<%@ page import=\"XcForm.MainFrames\"%>"); //I have a hunch that this statement is the problem
out.println("<%");
out.println("MainFrames mainframes = new MainFrames();"); //without the import statement above, the MainFrames.java class is not being recognised
out.println("%>");
out.println("}");
out.println("</script>");
Thanks in advance,
Tejas

Do not put presentation code in servlets. Put them in JSPs. And mixing serverside code (scriptlets) and clientside code (javascript) this way is indeed not going to work. That code will certainly not be executed in the order as you write. Serverside code is executed at the server and is finished when the response is completed. So any serverside code inside clientside code is alreay executed. Clientside code is executed at the client and will only execute when the response is completed (onload, etc) or when the client invokes it (onclick, onsubmit, etc). Further on, do not put business code in presentation code. Put them in servlets.

JSF 1.2 with SERVLET 2.3

Hi, i've download the latest JSF 1.2 RI but i can't see any page as i get the following error:
ava.lang.NoSuchMethodError: javax.servlet.http.HttpServletResponse.getContentType()Ljava/lang/String;
at com.sun.faces.context.ExternalContextImpl.getResponseContentType(ExternalContextImpl.java:277)
at com.sun.faces.renderkit.RenderKitImpl.createResponseWriter(RenderKitImpl.java:167)

at javax.faces.webapp.FacesServlet.service(FacesServlet.java:198)
The getContentType method that the exception describes is only available in servlet 2.4 but i'm using a servlet 2.3 only container. Can i use JSF 1.2 with servlet 2.3 ?
Thanks

I'm 90% sure that you cannot. JSF 1.2 is intended to be part of Java EE 5.0. Since Servlets 2.3 are part of J2EE 1.3, I don't think that it will work.
