Listening to HTTP request events. Question related to enableEvents property.

          Hi,
          I am using weblog 5.1 service pack 6.
          I am interested in HTTP request events. So I did the following.
          I have registered interest in the topic WEBLOG.LOG.HTTPD. I have changed the weblogic.properties
          file to include the following line.
          weblogic.httpd.enableEvents=true.
          But when I bring up the server it says it "Found an undeclared property weblogic.httpd.enableEvents".
          And it is not publishing any events to the topic when I hit the server (probably
          because of the previous message). Can you help?
          Thanx
          Trisula P. Siripurapu

regarding error:
Caused by: org.omg.CORBA.OBJECT_NOT_EXIST: Unknown object in LOCATE_REQUEST vmcid: 0x0 minor code: 0 completed: No
Make sure to place the wlfullclient.jar at the beginning of the classpath ...any other WLS specific Jars need not to be added additionally. For above error please refer to : Client SAF error
Few Things:
1). When I execute the ant build from a remote box , should I have a weblogic server running...the reason I ask is..does the wldeploy task work only if there is an active weblogic domain in the local machine. When I execute the same build from my windows machine where I have a local instance of weblogic , it works uccessfully .Whenever you try to deploy any application on WebLogic Domain then the Admin Server must be running. Because the deployment entries goes inside the "config.xml" and the original copy of this file is maintained by AdminServer only. So the Admin Server must be running for any kind of configuration changes or for Deployment.
2). I am told that http protocol is not an option in my work place and I have to use t3 protocol only. In that case, based on the error below, is it possible that the connection between my local unix box and the remote weblogic box is stricted? How to I test the connectivity using t3? I pinged the server from the local unix server and it came back with reply, but could not telnet to that remote box nor ftp to that box does not work.You can check t3 protcol is working fine or not by using the following one line command:
java weblogic.Admin -url t3://he3unxd189v01:9100 -username weblogic -password weblogic PING
If above command fails to ping the server it means either you are using a wrong HostName & Port OR your N/W is doesnot allow t3 protocol connections OR there may be a N/W Issue.

Differentiating HTTP Request through a URL and a value change listener

Version Details:
Oracle JDeveloper 11g Release 1 11.1.1.4.0
Studio Edition Version 11.1.1.4.0
Build JDEVADF_11.1.1.4.0_GENERIC_101227.1736.5923
IDE Version: 11.1.1.4.37.59.23
Product ID: oracle.jdeveloper
Product Version: 11.1.1.4.37.59.23
ADF Business Components 11.1.1.59.23
Java(TM) Platform 1.6.0_21
Oracle IDE 11.1.1.4.37.59.23
Versioning Support 11.1.1.4.37.59.23
Base Details:
The Product, that a different team is working on (which I cannot access, code, touch,...), creates reports and essentially generates a URL with a bunch of parameters:
http://<host>:<port>/myApplication/main.jspx?parameter1=value1&parameter2=value2...When the user clicks on an "Edit" button, a modal popup window is displayed (using jQuery) with an embedded iFrame with its source pointing to the above URL.
The "myApplication" is an ADF application which brings up an ADF form based on the parameters. Once the user enters the data, validations occur and the data is written into a total of 3 different Tables in the Database. Once the operation is finished, the user closes the popup by clicking on the "X" button of the popup window, which essentially does "popup.*hide()*".
Limitations:
<li>Since there are varied combination of parameter values and associated ADF forms, taskflows is not* an option.
<li>Since the logic of generating the ADF form is not straightforward, ADF BC is not* an option.
<li>Since validations are based on the value change listeners, the managed bean has to be a session scope_ bean.
Problem:
When, for the first time, the user clicks on the Edit button with a particular set of parameter values, the corresponding ADF form is displayed and things work normal. Since the managed bean is under session scope, the form generated for the first popup window stays the same for any subsequent popup windows, even when the URL and its parameters are completely different. As I can not listen to the popup close event, I cannot invalidate my session either.
I tried using filters in the web.xml to grab the request and apply the business logic. Due to the presence of multiple value change listeners (too many <tt>autosubmit=true</tt>), every value change listener triggers a request and so the business logic gets applied with every value change.
After some tests, I deduced that the difference between the call from iFrame and the call from value change is the HTTP Request Method - GET for iFrame and POST for value change listener. So in my filter I apply the business logic when there is a GET request and not apply when its a POST request.
Turns out, that is not a valid enough differentiation between the two requests being made. Sometimes, even the value change listeners are issuing a GET request.
Question:
*1*. Is there a way to force the value change listeners to always trigger a POST request?
*2*. Is there a way to differentiate the requests originating from the other team's Product and those generated by my own value change listeners?
*3*. Is there a different approach, incorporating the above-mentioned limitations, to clear out the session scope each time when a request is made through iFrame? That is, whenever a request is made through the other team's Product?
Edited by: user737922 on Apr 13, 2011 10:58 AM

_(Temporary) Solution_:
Summary:
I am using the request parameter <tt>_adf.ctrl-state</tt> to differentiate between the HTTP requests that my application receives.
Details:
When I receive the request from the other team's Product, I receive a <tt>GET</tt> and a <tt>adf.ctrl-state</tt> value which I store into a local variable in my session-scoped managed bean. The <tt>adf.ctrl-state</tt> value stays the same for all requests (<tt>GET</tt> or <tt>POST</tt>) made from within my own application. It changes only when there is a new request from the other team's Product.
Also, as my application is accessed through an iFrame, there is no possibility of the generated URL being modified by the end-user.
For now it seems that the solution is appropriate but I am not fully confident if relying on the <tt>_adf.ctrl-state</tt> value is the best approach.

Get Http Request in Session Listener?

Is it possible get Http Request in Session Listener when session is created? I need to get cookies when session is created.
anyone knows?

No, it is not possible.

Listen to "ALL" HTTP Requests

Hello,
I have an application with many 3rd party components on it.
These components pull in a lot of external media (i.e images, data) but do not have a public Loader i can listen too.
Is there any way Flex can give me access to all HTTP request coming in so I can show a progress bar for each download?
Thoughts?
Drew

LinKe,
I do not believe this is possible. The port associated with the URL of the Web Service Reference is determined from WSDL at the time of definition. There is no facility to alter the Web Service Reference definition at runtime.

Enabling event-based HTTP request information

Hi all,
 The BEA documentation on 'Setting up WebLogic as qan HTTP server
 prescribes in order to enable event-based HTTP request information:
 1.Set the property weblogic.httpd.enableEvents to true in the
 weblogic.properties file, as detailed in the WebLogic Administrators
 Guide document, Setting WebLogic
 properties.
 2.Start the WebLogic Server and register an interest in the event
 WEBLOGIC.LOG.HTTPD.
 I have no idea what to do in order to fulfil 2.
 Does anybody have an idea?

Allow-http-request-headers-from Question

I have a crossdomain.xml file in place, but am still getting this error:
"Security error accessing url"
I searched the web and is it true that because I am accessing a SOAP web service I need to add this to the crosssdomain.xml file:
<allow-http-request-headers-from domain="MYDOMAINHERE" headers="SOAPAction"/>
Is there anything else from a crossdomain.xml file perspective, or anything else in general to be able to access these web services from my Flex app?
Thanks for your responses.

The SWF is at MyDomain.com (for example).
The crossdomain.xml file is on the 3rd party web service provider at the root of their web server, and it correctly has an entry to MyDomain.com.
The exact error is "Security error accessing url".
I read on the web that when accessing SOAP web services you need to add these entries to the crossdomain.xml file:
<allow-http-request-headers-from domain="MyDomain.com" headers="SOAPAction"/>
Is that the case and is there anything else extra I need to do to get web services to work in this case?
Thanks Alex, for helping with this.

Creating listener for incoming http requests

Hi,
I am trying to create a server for incoming http requests.
I am using Connector.open("socket://:5555") call to bind to the server socket.
I have give permission for Connector.socket, as well as Connector.http to this application.
The server is able to accept connections when the client connects using socket://localhost:5555, but does not accept any incoming connection when the client connects using http://localhost:5555.
How can I create a service on my mobile which will accept http requests.
Thanks,

Behaviour of Service (MqActive and http-requests)

Hello,
I have a servlet which runs an mq-active listener and get input by http. Now my question: what is important about threads and concurrency ? - There could be the case, that the mq-active-listener gets an Message while there is an http-request. Should I start for each request of mq-active a new Thread?
thanks for you answer,

Hi David,
Thanks for correctly guessing our longer term plans. It's good to know this won't be a problem in the future.
However, that doesn't answer my original question, which is a bit more pressing than waiting until we have migrated. If it can't be done, it can't be done, and we'll just bear that in mind when responding to failover events. But I would prefer
a definitive "no, it can't" rather than a speculative "no".

How can I tell if my local webserver is configured to accept https requests?

I have phpMyAdmin on my localhost server.
How can I tell if the localhost server is configured to accept https requests? Or is that unnecessary on a localhost server?
Below is the info from the phpMyAdmin home page:
Server: 127.0.0.1 via TCP/IP
Server version: 5.0.81
Protocol version: 10
Apache/2.2.20 (Unix) mod_ssl/2.2.20 OpenSSL/0.9.8r DAV/2 PHP/5.3.6
MySQL client version: mysqlnd 5.0.8-dev - 20102224 - $Revision: 308673 $
PHP extension: mysqli
phpMyAdmin
Version information: 3.3.1
Many thanks for information and advice concerning this.
Best,
Sheley

Well, for one, by definition, localhost can only ever be accessed from the machine itself. It doesn't get any more secure than that.
However, just because you're hitting the site on localhost that doesn't mean that Apache isn't also listening for connections on other IP addresses. In fact, by default, Apache will listen on all IP addresses configured on the machine.
Therefore you might want to look a little deeper.
You can see from the phpMyAdmin output that Apache is configured to support HTTPS, but that only tells you whether apache knows how to speak HTTPS, not whether the current connection/request is using HTTPS.
The shortest, simplest answer to your question is to try. If you can hit https://localhost/ then, yes, Apache is listening and responding to HTTPS requests. If it doesn't respond then it isn't.
Or dig through the configuration files, but I'm guessing if you knew how to do that, you wouldn't be asking the question.

Question related to Java Concurrent Program

Hi Friends,
I have a basic question related to Java Concurrent Program in the Oracle application. I would like to know the how Java concurrent program is executed in Oracle applications.Also, want to know where can I find the document for the AOL packages for Java concurrent program. Document for packages like oracle.apps.fnd.cp.request.* , oracle.apps.fnd.util.*.
Please let me know.

Web server / http requests

Hi,
I am attempting to implement a listener on my server for http requests. Also, messages will be sent though using SOAP.
My question is, can this listener run as a standalone service? or do I need to implement a web server and perhaps create a servlet to respond to anything coming through via http?
I am unsure of the advantages / disadvantages...Any help or assistance would be greatly appreciated.
Thanks
Gregg

You can write a program that listens at ports for connections.
But the advantage of using a web server and writing servlets, is that a lot of the hard work, the little tedious work with low-level networking stuff, is done for you.

Multiple HTTP Requests in for loop response handling

i am working on stock market portfolio. a user saves his stock name , buy price ,etc .i've added this details in database.but while viewing his portfolio he should even get the current price of d stocks he has added. while retrieving i fetch all data from database set them in a bean and for each stock i make a HTTP Request. in result handler i event set the current price into the bean. Problem is my entire application is displayed with all the CurrentPrice fields with null.
private function selectContacts():void
 trace("select before");
 stmt.sqlConnection = this.isDbConnected(conn);
 stmt.text = "SELECT * FROM stocks_t";
 stmt.addEventListener(SQLErrorEvent.ERROR, sqlError);
 stmt.addEventListener(SQLEvent.RESULT, sqlResult);
 stmt.execute();
 trace("select after");
private function sqlResult(res:SQLEvent):void{
 httpServ = new HTTPService();
 data1 = stmt.getResult().data;
 stockList = new ArrayCollection();
 for(var d:int=0;d<=data1.length-1;d++)
 myPortfolioBean = new MyProtfolioBean();
 httpServ.url = 'http://quote.yahoo.com/d/quotes.csv?s='+data1[d].stockName+'&f=snl1a';
 httpServ.method = 'GET';
 httpServ.addEventListener(ResultEvent.RESULT,yDataResult);
 httpServ.addEventListener(FaultEvent.FAULT,yDataFault);
 httpServ.showBusyCursor= true;
 httpServ.send();
 myPortfolioBean.stockNameB = data1[d].stockName;
 myPortfolioBean.buyB = data1[d].buy;
 myPortfolioBean.quantityB = data1[d].quantity;
 myPortfolioBean.totalQuantityAmountB = data1[d].totalQuantityAmount;
 myPortfolioBean.profitB = data1[d].profit;
 stockList.addItem(myPortfolioBean);
public function yDataResult(evt:ResultEvent):void
 var s:String = evt.result as String;
 var a:Array = s.split(",");
 //To add to a form or individual fields
 lastTraded = a[2].toString();
 lastTradedFloat = parseFloat(lastTraded);
 myPortfolioBean.currentB = lastTradedFloat;
 stockList.addItem(myPortfolioBean);
 //stockList.addItem({current:lastTradedFloat});
the yDataResult() is called after the entire datagrid is displayed on screen as a result of which the CurrentPrice in datagrid column in null. Eg: user has added google ,yahoo,apple( CurrentPrice is null for all three values) after some time three more rows (as a result of call to yDataResult) with CurrentPrice xx.xx displayed. I want merged results.

hello ,
"CurrentPrice" is "lastTradedFloat" sorry for the ambiguity.
and u got my problem but there is an issue ..
all the results are set using "sqlResult" except the "lastTradedFloat" which is set in "ydataResult".
but i confused with HTTP ResultEvent Execution.
first "sqlResult" method is called arrayCollection is populated. then result is displayed on screen.( lastTraded value is null then)
then "ydataResult" executes again manipulating data in arraycollection.
what i want is data in "sqlResult" and "ydataResult" to be set sequentially then callin my display page . such that display is correct.

The MAC signature found in the HTTP request '***' is not the same as any computed signature. Server used following string to sign: 'POST

Hi,
When trying with Postman sending a REST call to Azure Storage Queues I get:
The MAC signature found in the HTTP request '***' is not the same as any computed signature. Server used following string to sign: 'POST.
The code I have for creating the Authorization Header:
var accountName = "my_account";
string key = ConfigurationManager.AppSettings["my_access_key"];
DateTime dt = DateTime.Now;
string formattedDate = String.Format("{0:r}", dt);
var canonicalizedHeaders = "x-ms-date:" + formattedDate + "\n" + "x-ms-version:2009-09-19" + "\n" ;
var canonicalizedResource = "/my_account/myqueue/messages";
var stringToSign = String.Format("POST,\n\n\n\n\n\n\n\n\n\n\n{0}{1}", canonicalizedHeaders, canonicalizedResource);
stringToSign = HttpUtility.UrlEncode(stringToSign);
HMACSHA256 hmac = new HMACSHA256(Encoding.UTF8.GetBytes(key));
var signature = Convert.ToBase64String(hmac.ComputeHash(Encoding.UTF8.GetBytes(stringToSign)));
var authorizationHeader = String.Format(CultureInfo.InvariantCulture, "SharedKey {0}:{1}", accountName, signature);
return authorizationHeader;
Anyone any idea what I'm missing/doing wrong?
Additional question: do i have to create for every message I want to send a new Authorization header? Or is there an option (as with Service Bus Topics) to create a header that can be used for a certain timeframe?
Thanks.

One issue is with this line of code:
HMACSHA256 hmac = new HMACSHA256(Encoding.UTF8.GetBytes(key));
Please use the following:
HMACSHA256 hmac = new HMACSHA256(Convert.FromBase64String(key));
and that should take care of the problem.
Regarding your question, "do i have to create for every message I want to send a new Authorization header? Or is there an option (as with Service Bus Topics) to create a header that can be used for a certain timeframe?"
With your current approach, the answer is yes. What you can do is create a Shared Access Signature on the queue which will be valid for certain duration and then use that for posting messages to a queue using simple HttpWebRequest/HttpWebResponse.
Hope this helps.

HTTPS request signed by client certificate from PL/SQL procedure

Hi All, please help.
The PL/SQL procedure connects to different web services, using both HTTP/HTTPS, for HTTPS sever certificates were used. Everything was OK.
The next service requires client to sign requests with client certificate. I made the client certificate, sign it by CA, store it in Wallet Manager.
Is here the possibility to send signed HTTPS request from PL/SQL?
If not, how to do it using Java and encapsulate for PL/SQL?
Please answer ASAP!!!

It is pretty straight-forward to make HTTPS requests with UTL_HTTP.
To do so, you first need to create an Oracle wallet on the database server host with Oracle Wallet Manager. If your database resides on Windows, I believe a short-cut has been created in the Windows menu. On Linux, it can be invoked from $ORACLE_HOME/bin/owm.
Once the wallet is created, you need to make an additional call to utl_http.set_wallet(<wallet-directory>, <wallet-password>) before any utl_http.request or utl_http.begin_request calls. The <wallet-directory> is the wallet directory where you will find the cwallet.sso and/or ewallet.p12 files, using the format "file:/<wallet-directory>". For example:
utl_http.set_wallet('file:/home/oracle/wallets/my_wallet/', '123456');
When an Oracle wallet is created, it is pre-populated with common certificate authorities' certificates (e.g. Verisign). In the event that the server certificate of the HTTPS host is not signed by one of those common certificate authorities, you need to import the additional certificate authority's certificate in your wallet using Oracle Wallet Manager.
