Blazeds help
So I have a problem that has been bothering me for a few weeks now. My backstory is a Flex front end that connects to a java backend located on the same server. It is running on a tomcat server. When you are inside the firewall everything runs fine in firefox but crashes in IE. When outside the firewall you can reach the swf but get back a very long server 500 error. This is my remote object:
<mx:RemoteObject id="ldapConnect" destination="ldapService" showBusyCursor="true"
endpoint="https://servername/blazeds/messagebroker/amf">
<mx:method name="getAllUsersXML" result="getAllUsers(event)" />
<mx:method name="clearCache"/>
</mx:RemoteObject>
this is part of my services-config.xml file

Help Needed in developing simple Chatting application using flex and blazeds
Hi,
I followed this tutorial from adobe http://learn.adobe.com/wiki/display/Flex/Creating+a+BlazeDS+messaging+application+in+Flex+ Builder i installed tomcat server and set the path.I am unable to open server like this http://localhost:8080 but i can able to open that in this way http://127.0.0.1:8080/ .... When i create my new flex project in flash builder 4 i am getting this error
You do not have write permission for the project output folder. Specify another location.
can any one help me in how to get rid of this problem.I hope this forum helps me in finishing my flex project..
Thanks
TrinethraHi,
Need to use a scrollable resultset and depending on the need to have a stateful connection or a stateless connection you may need to query the table for every request(for stateless connection) and use the same result set for(stateful connection). and depending on the no of records in a page and the page no do some simple arithmetic and move the resultset. Hope this helps.

Exception deserializing from BlazeDS with the help of [RemoteClass] metadata
Hi,
In my BlazeDS application (AMF based), I am throwing two kind of java Exceptions:
TechnicalException extends RuntimeException : this one is thrown to the Flex client when any unexpected error on the server is caught
BusinessException extends Exception : this one is a base class for business-related exception
On the Flex side, I created the same Exception classes mapped to the Java ones using the [RemoteClass] metadata tag.
In the error event handler of my RemoteObject call, I am looking at the event.fault.rootCause property for fully typed flex exception class, so that I can simply switch my behavior depending on the received exception. I observed the following behavior:
When throwing a java TechnicalException from the server, it is correctly deserialized as a flex TechnicalException on client side. So the assertion "event.fault.rootCause is TechnicalException" is working fine.
When throwing a java BusinessException from the server, it is NOT correctly deserialized as a flex BusinessException on client side. So the assertion "event.fault.rootCause is BusinessException" is NOT working.
The only reason I see for that is that only RuntimeExceptions can be deserialized strongly typed on Flex side. Is it the nominal behavior of the Flex RemoteObject or did I miss something ?
Many thanks in advance for your help,
Avangel.Ok, I finally found the answer to my problem. For those interested, the cast of java Exceptions into ActionScript Exception is working exactly like any other class. It has nothing to do with whether the java class extends RuntimeException or not, or any other class / interface. It just doesn't matter at all. Flex RPC simply looks for an AS class mapped to the received Java class through the [RemoteClass] metadata tag. If it finds it, it just try to map fields from java object to AS object (even if a field is not matching, it just ignores it).
So the problem was a very well-know AS compiler problem: AS classes that are used only at runtime for conversion are not compiled in the SWF. In other words, if you have not any class that references your Exception class, that one won't be included in the SWF file, so the RemoteObject won't find it, thus returns an Object instead of strongly typed AS class.
Hope this may help someone

Need help in Delete operation using blazeDS
Please find the flex client code and servlet code given below
Trying to call a DELETE methods on the servlet using BlazeDS.Configuration is perfect in the proxy-config.xml and services-config.xml
when DELETE is called with paramter user="krishna it is being printed as
received DELETE operation with parameternull
My Question is why the servlet printing null value for the user where it should print "someuser"?Can some one help me on this?

Experts Help!! Fiendish BlazeDS / Single Sign-on (NTLM) problem
Guys,
I've been tearing my hair out for a month with this problem - any help would be most gratefully appreciated!
I need to get a flex app working with single-signon on the windows platform.
I want to grab the windows username and domain from the browser without having users enter by hand.
I will then authenticate against my own repository tables accessed via remote objects (blazeds + spring flex + spring + hibernate)
I have a servlet that uses NTLM authentication challenge response. The servlet works on its own returning usename and domain.
See below for servlet code
HOWEVER - no matter how i call the servlet from flex it seems to totally screw up blazeds. No further remote object calls are possible.
The same remote call works before but not after the servlet has been called. Its driving me insane!!!
I suspect the problem is related to how the single initial call to the servlet from Flex results in a further two executions of the servlet.
I assume Internet Explorer is initiating further calls.
I've tried calling it in the following ways...
- HTTPServce with URL
- HTTPServive with blaze destination
- From within actionscript
- From MXML
- From a flex module
- from the javascript wrapper using XMLHttpRequest and flashvars
- With one trouser leg rolled up and my finger in my ear
Every single time it stops any further remote object calls from working they get as far as
[BlazeDS][DEBUG] FlexSession created with id 'ADF15BED993AD562EEA9249EE6B33CED' for an Http-based client connection.
[BlazeDS][DEBUG] Deserializing AMF/HTTP request
but know further.
Clever people please help - before i blow my brains out!! ;-)
Thanks in advance
GaryI have the same problem.
1) Open page with a swf using BlazeDS for remoting. Works fine
2) Go to other page doing NTLM authentication. Works fine.
3) Go back to the first page, BlazeDS remoting does not work anymore.
Did you find a solution? -
Hi
I need some help on blazeDS.I am pretty new to blazeDS.i am finding it difficult to configure remote configuraton from my flex builder.I have got a coldfusion server which is deployed inside the Weblogic server as a web application.So i choose my server as ColdFusion and selected deployed in J2EE(Radio button) Whenever i select ValidateConfiguration I get the error LiveDataService not installed in the specified location.My requirement is i need to call both CFCs as well as Java classes .It will be of great help if somone helps me out to get my configuration right.

How to get blazeds to talk to oracle help!
I have decided to experiment with blazeds and see if I can get it working everything was going fine i follow several tutorials and i was able to get everything running just fine on my pc. Then i decided to extract records from local oracle database thats when everything went south. If i debug the application in java i get a resultset back from my java class but when i attempt to query the java class i get this nasty error.
faultString="java.sql.SQLException : No suitable driver found for jdbc:oracle:thin:@//192.168.1.6:1521/exe" faultCode="Server.Processing" faultDetail="null"]
I have added the ojdbc14.zip file to my build path i have referenced it anywhere possible and still nothing??? has anyone else experienced this problem in the past? is rather frustuating been added the whole day now and i can get rid of this error? If i debug the java class locally. it works like a charm but when i attempt to call from flex using blazeds its all south.
Hope someone can throw me a bone on this one.
Thanks
Miguelfollow your directions to the 'T' and its definitely a zip i changed the file to .jar and now im
getting a different error.
faultString="java.lang.NoClassDefFoundError
java.lang.NoClassDefFoundError : oracle/jdbc/driver/OracleDriver"
very weird. -
Need help with Flex, BlazeDS and Spring
I have a configured Flex-Blaze-Spring application. I can call
a remote method on a Spring bean and pipe its results, (list of
pojos), to a DataGrid and the grid displays the data. The remote
object is defined with a <mx:> tag, defining a handler
function that pipes the result as ArrayCollection to the DataGrid's
data provider. I now want to perform another call to the remote
Spring bean, but this time define the remote object in
ActionScript, and pipe the results to a ArrayCollection variable
that I can then iterator thru and pick off values from attributes
of the objects in the ArrayCollection. I can't set access, my
collection seems to be empty. Here is some code:
public var gameRO:RemoteObject;
public var weeksGameList:ArrayCollection;
public function makePickGrid():void {
pickPanel.removeAllChildren();
var pickGrid:Grid = new Grid();
var gRow:GridRow = new GridRow();
var gItem:GridItem = new GridItem();
var cb:CheckBox;
gameRO = new RemoteObject();
gameRO.destination = "gameService";
gameRO.getWeeksGames.addEventListener( ResultEvent.RESULT,
getWeeksGamesResultHandler );
gameRO.addEventListener( FaultEvent.FAULT, handleFault );
gameRO.getWeeksGames( curWeek.selectedItem );
for each (var game:Object in weeksGameList) {
cb = new CheckBox();
cb.label = game.awayTeam;
gItem.addChild( cb );
gRow.addChild( gItem );
pickGrid.addChild( gRow );
pickPanel.addChild( pickGrid );
public function
getWeeksGamesResultHandler(event:ResultEvent):void {
weeksGameList = event.result as ArrayCollection;
What am I missing here? Thanks for any help!!
mikHello
This is a bit of a wild guess, but looking at the code, is it possibly related to the scope of cb?
Why not declare it inside the for loop, rather than outside it? -
Tomcat JSP HTTP Services, BlazeDS and AMF Help Understanding This in Cairngorm
Hi
I have an existing Tomcat application using JSPs and a Flex Client that uses HTTPService (Cairngorm). Can we use BlazeDS to access these JSPs over AMF? How might that work in Cairngorm.
ThanksThere may be other ways to do this but here's what I would do:
1) add a results method to the remote object:
src.result="onResult(event.result)";
2) add the callback method: private function onResult(event : * = null)
:void{
if(event is
ArrayCollection)
myData =
ArrayCollection(event);
3) add the variable: private var myData:ArrayCollection;
4) make the dataProvider for the grid use the my data :
dataProvider=""
You can probably avoid all this by adjusting your dataProvider. I am just
not sure what it would be without experimenting. But definitely not what
you have. Maybe just {svc.result}. -

</service>Hi!
I am using Flash Builder 4.6, BlazeDS, and Hibernate. How to store a webcam snapshot into the MySql Database. I stored Form Items by using RemoteObject into the database. But I failed to store webcam snapshot. I captured that image on Panel component.I converted that image to ByteArray. Now I want to save that image into the database. Please help me in this regard.
thanks in advance.

Background:
- Using Flex Builder 3 plugin for Eclipse
- Downloaded latest BlazeDS release build
- Running Tomcat 6.0.16
=======
First I want to note the samples that come with BlazeDS run
absolutely fine.
So I created a new project in Flex Builder 3. I'm just trying
to get something simple working at first so my one mxml file is as
follows (I stripped out everything except the code in question):
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:RemoteObject id="ro"
destination="enrollmentService"/>
<mx:DataGrid
dataProvider="{ro.getEnrollmentList.lastResult}" width="100%"
height="100%"/>
<mx:Button label="Get Data"
click="ro.getEnrollmentList()"/>
</mx:Application>
=====
I created and EnrollmentService class and I'm sure it's
getting compiled to WEB-INF/class...I see .class file there.
I added the flex folder to the WEB-INF folder. My
remoting-config.xml is as follows (because of problems I specified
a default and repeated it to be sure):
<?xml version="1.0" encoding="UTF-8"?>
<service id="remoting-service"
class="flex.messaging.services.RemotingService">
<adapters>
<adapter-definition id="java-object"
class="flex.messaging.services.remoting.adapters.JavaAdapter"
default="true"/>
</adapters>
<default-channels>
<channel ref="my-amf"/>
</default-channels>
<destination id="enrollmentService">
<properties>
<source>test.service.EnrollmentService</source>
</properties>
<channels>
<channel ref="my-amf"/>
</channels>
</destination>
</service>
My services-config has the following channel defined:
<channel-definition id="my-amf"
class="mx.messaging.channels.AMFChannel">
<endpoint url="
http://{server.name}:{server.port}/{context.root}/messagebroker/amf"
class="flex.messaging.endpoints.AMFEndpoint"/>
<properties>
<polling-enabled>false</polling-enabled>
</properties>
</channel-definition>

So I start Tomcat from Eclipse and run the app by clicking
the Run button in Eclipse. The app comes up fine, but when I press
the "Get Data" button. I get the error message below. For the life
of me I don't understand why. I clearly have a default channel AND
I have specified a channel. This is so frustrating...any help would
be greatly appreciate.

FlexJ2EE_test/___FlexJ2EE_test_Button1_click()[C:\Prj\workspace\RemoteTest\flex_src\Remot eTest.mxml:36]While creating a Flex project using Flex builder, did you
select the server type for your project? If you did not select a
server type for your flex project, did you configure your compiler
to include your services-config.xml using the -services argument?
In your project's compiler settings, add -services
"configurationfiles/services-config.xml" argument to the compiler
arguments. The path should point to your services-config.xml.
If the above mentioned steps were completed and still your

Debugging Deserialization Errors Between AIR and BlazeDS on ColdFusion using ORM
Now that I am using CF + ORM for most of my Flex and AIR projects, I've had a much more difficult time with the deserialization of objects from AS to CF. The errors thrown by BlazeDS are not helpful at all, and not indicative of the true issue. cfgatewayadapter.jar is a closed source, and make it even more difficult, because it is the culprit in these issues. These issues can sometimes take a full day or two to resolve because the only way I've seen to debug is to start removing code line by line until the thing works. Huge waste of time.
The problem stems from the fact that during deserlization CF barfs when something doesnt match. Instead of throwing a useful error, it proclaims the CFC doesnt exist serverside. The developer then has to go through each componenty property-by-property to try to determine where the problem is.
What we need is something more specific to what the actual problem is. I've not found an adequate way to debug this, and it's causing me to seriously considering changing the backend to Groovy + Granite so I can get the control I need. Really, Adobe just needs to open up the source on cfgatewayadapter or put some time into refining it so that it throws accurate errors.
Examing the error below, one would think that the CFC does not exist. However, if you run the same examples from CFML and pass it an instance of StreamProvider it works fine.

Blazeds 4.0.0.7548 is not working on Websphere over HTTPS protocol
Hi All
Our application is on Blazeds 4.0.0.7548 deployed on websphere 7.0. While this application works fine on HTTP but it doesn't work consistently on HTTPS. It throws following exception
FaultEvent fault=[RPC Fault faultString="error" faultCode="Channel.Call.Failed" faultDetail="NetConnection.Call.Failed: HTTP: Failed"] messageId="C6ABB836-C505-CAFC-F114-0006E0E0305F" type="fault" bubbles=false cancelable=true eventPhase=2.
Following is the screeshot
I don't see any exception in the logs as well.
HTTP works fine, i only see this exception on HTTPS.
Regards
RaviAs I mentioned earlier, we are using MGCP for that particular fax port and the gateway we use as H323.
Even I'm not pretty sure about using mixed protocol, I believe this gateway gonna used to support call center calls. SInce MGCP is easy for configs they might have confiugred only the port as MGCP endpoint.
Now its not working with both the cases, not in mgcp as well as fallback mode. Can you reveiw the debugs and see why I have to remove "modem passthrough" command from voice service voip section which of our standard config and works well with all other gateway of ours. Please help here. -
Invalidate connection to BlazeDS server when closing tab in browser
There is an issue using IE and blazeds. When you establish a connection to blazeds from a tab of your browser, even when the tab get closed, she connection remains. The session doesn't get invalidated. It looks like it works fine in Firefox but it's an issue in IE.
It is especialy important if you are build a chat room for example ... you want to know precisly when someone is leaving the room.
I finally found an answer to this problem. I didn't find any answer on the Internet so I felt that I should share it.
I invalidate the session on the server side using a servlet.
Here is the code:
In my flex app html template I add:
<script langugage='javascript'>
function disconnectAll(){
if (navigator.appName == "Microsoft Internet Explorer")
xhr = new ActiveXObject("Microsoft.XMLHTTP"); // Trying Internet Explorer
else
xhr = new XMLHttpRequest();
if (xhr) {
xhr.open("GET", "../disconnect", false);
xhr.send(null);
</script>
</head>
<body scroll="no" onunload="disconnectAll()" >
This call to ../disconnect does a http request to my servlet that will invalidate the connection.
Here is the servlet code:
public class Disconnect extends HttpServlet {
private static final long serialVersionUID = 1L;
@Override
public void doGet(HttpServletRequest httpRequest, HttpServletResponse response) {
System.out.println("doGet disconnect called !");
httpRequest.getSession().invalidate();
This has to be added in the web.xml for the servlet to be accessible:
<servlet>
<servlet-name>DisconnectServlet</servlet-name>
<display-name>DisconnectServlet</display-name>
<servlet-class>com.ms.advil.servlets.Disconnect</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>DisconnectServlet</servlet-name>
<url-pattern>/disconnect</url-pattern>
</servlet-mapping>
That’s it ! On the unload of the page, an Ajax request is made to the servlet that will invalidate the http session.
Your browser’s connections get invalidated and blazeDS catches the disconnection.
Hope this will help
