How does JavaFX connect to Web Servers?

Recently,I was learing about JavaFX and confused with the way that
1.how does JavaFX connection to Web Servers?
2.Is there anything related to SOAP protocol?
Please help me.Thanks.

I don't understand very well...
in the Web service style, is this Java code ? or JavaFX code
How can I use JavaFX to call a web service (not REST, just pure web service)
I did it by this article
http://netbeans.dzone.com/news/javafx-client-invoking-metro-e
But i have two problem.
1. when deploy as applet, there is security issue, how can i resolve ?
2. my application invoke easy web service is ok, but when invoke some complex type web service, there is error like this...

How does BPEL connect to JMS??

Hi All,
I have a BPEL process which basically logs a message into a JMS Q..This process runs forever and when ever a new message is to be logged we return the same instance instead of a new instace..
Now a couple of questions I have on this is -
How does the connection to JMS work,is it like there is 1 conncetion for the entire BPEL process which is used every time I wanna add a new message,or is it like a new connection is created and destroyed with every invioke to the JMS..
I need to make sure a instance of this process already exist so that I can return the same,is there any way my parent process can chek if there is an instance of the child process and if yes it will call that instance ,if No then it will create a new instance..
Is there any way I can initiate a BPEL process through ant?
It would be grt if any 1 can throw some light on these.. thnx..
Regards,
Akshatha

Each JMS queue/topic has a single persistent image. Any reference to that queue through the relevant connection factory returns the reference to the same instance.
There may be many different queues, but each is uniquely identified by its jndi name.
Name each of your JMS queues differently for each separate endpoint you wish to consume messages from.
You could use ant to initiate a process by invoking the web-service sending a soap message to the url for the processes web-service. I use soap-ui or the BPEL Console to manually do the initiation, and to determine what makes up the soap packet that is forwarded to the web service. I am not aware of any task that does this for you so you would have to construct a http type target yourself.

How does Openscript Interact with web components ?

I was wondering how does openscript interact with web objects (eg Edit boxes, buttons), is it through some JNI api ? If yes in which package I can find this ?

I am going to make the assumption from your comments that you are asking about using OpenScript to test applications based on Apple's WebObjects server. If that is a bad assumption let me know ...
The scripts you build against the application will work in a similar manner to those that are built against other java based application servers in that the tool will be using the various key attributes of the html objects to locate them and replicate actions against them. Typical UI driven scripting ... That said, if your testing brings you down a level from the UI and you are trying to test some of the components of the application server tier specifically, well, then you might have to write your own java code to do it.

How does client connect to RAC

I'm confused how client connect to RAC,
1) According to this:
http://www.datadirect.com/developer/odbc/odbc_oracle_rac/connecting/index.ssp
"a ServiceName exists for the entire Oracle RAC system. When an application uses the Oracle RAC system's ServiceName, the Oracle RAC system appears to be a single Oracle instance to the application"
so, seems client just make sure using service name instead of SID, it will be connect to RAC. the URL format is same as single non-RAC enviroment
2) however,according to this:
http://forums.sun.com/thread.jspa?threadID=5274308
The URL need to be:
jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on)
(ADDRESS=(PROTOCOL=TCP)(HOST=host1) (PORT=1521))
(ADDRESS=(PROTOCOL=TCP)(HOST=host2) (PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=service)))
this make RAC connect URL differenct from single non-RAC enviroment
if so, with this format, how does SQL developer connection set up? since you can only specify one host in connection properties configuration?
if so, adding a node will require all of client modify connect url?
3) my understanding is client only need to specify VIP to any one of node, and speicify global service name (all node should share same service name), this will make RAC connection setup (similar to above (1)), but I'm not sure if my understanding correct or not in the following senario:
-- a) what if client using public ip (not VIP) to one of node, but using global service name?
-- b) what if client using VIP to one of node, but using it's SID instead of global service name?
-- c) what if client using public ip (not VIP) to one of node, and using it's SID?
please clarify how does client connect to RAC?
Thank you!

Very good question.
You have asked in a certain way which tells me you have done lot of research.
Any how:-
Remember no matter how convoluting it looks it is the same.
1 Tns Entry
If you add a node then yes you have to publish it.
There are other alternatives such as Oracle Names [old]
internect directory , ldap and so on, beyond the scope of this discussion.
1)
TNSNAME Entry
RAC.WORLD=
DESCRIPTION=DESCRIPTION=(LOAD_BALANCE=on)
(ADDRESS=(PROTOCOL=TCP)(HOST=host1) (PORT=1521))
(ADDRESS=(PROTOCOL=TCP)(HOST=host2) (PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=service))
Now see The same string from DESCRIPTION onwards goes to jdb thin client, it
is the same thing...
Also the host1 host2 are all VIPS'
Also you need failover , load balance thingies in there
-- a) what if client using public ip (not VIP) to one of node, but using global service name?
non vip, Test it out, tns should hop over it .
but TAF /FAN won't work.
-- b) what if client using VIP to one of node, but using it's SID instead of global service name?
You have to use SERVICENAME, if you are using SID then you are pretty
much connecting to 1 node.
-- c) what if client using public ip (not VIP) to one of node, and using it's SID?
Then you are using 1 node rac.

How does Imac connect to the internet?

How does Imac connects to the internet?

Through your ISP (internet service provider); once you set up an account with them, you can decide to connect via ethernet cable to their modem, or, if you have a router (which is connected to their modem, you can connect wirelessly.
Is that what you were wondering about or did I misunderstand your question?

How does application connect/commincate to Message Broker + JMS

With reference to JMS,
I am wondering how does my application (consumer or producer) communicate to Message Broker(in my case it is ActiveMQ).
if the consumer is at HostA, producer is at HostB and ActiveMQ=message broker is at HostC

Mail does not connect to mail servers after 10.5.7 update

Updated Macbook Air with 10.5.7 update. The update went without problems.
After starting the computer, the Mail program does not connect to the mail servers - IMAP, POP, SMTP.
Otherwise the internet connection is OK for other programs, connection is through WIFI - Airport Extreme, Time Capsule... In all cases the same problem with Mail - showing the following
The server error encountered was: The connection to the server “mail.mac.com” on port 993 failed (error 1: Operation not permitted)
The connection doctor shows
Mail was able to connect to the internet
and for all the servers - could not connect, check your connection...
Did repair of keychain and permissions - no change in status of Mail... any ideas?

This is what shows up in console: (maybe someone who can understand this can help us!)

How does WebMail connect to the Mail Store

Some WebMail products have HTTP connect directly to the Mail Store Database. Other products have HTTP connect to IMAP and let IMAP connect to the Mail Store database.
How does iMS5 do it?

Hi,
iMS use separated daemon(mshttpd).
It is composited httpd daemon + message access daemon.
It is not normal http daemon.(mshttpd can use only
iPlanet Messaging Server)
When user connect the server using iMS 5 Webmail
(It is named Messenger Express), the mshttpd recevied
that requst and communicate with stord(mail box daemon)
and fetch the mail, and make new html page.
user -> mshttpd -> stored -> server mailbox
Other Webmail use IMAP or POP Protocal(standard protocal) for communicate
with messaging server, but mshttpd use itself protocal.
(It is not standard)
But, you can use imap of pop protocal for making new
webmail server.

How does TM find remote backup servers?

I have an OSX10.5.3 server that wired users can see as a Time Machine backup server. This works.
Wifi users (who are bridged onto the same wired network) can not see any remote Time Machine drives to backup to. Looks like the wifi controller (Cisco WLC) isn't forwarding some packets to the wired network.
How does a TM client find remote servers? Can remote servers be statically configured on a client?

There is a Find Systems VI on the Real-Time / RT Utilities / System Configuration palette that can find some things (like PXIs) on the network.

Ping - How does one connect with Facebook?

I see the message to connect with Facebook but do not see a link or instructions. Can someone show me how?

I got ping earlier today, and i was asked to connect to facebook. i tried and after multiple attempts it still wasnt working, it would never load. Eventually, i found out that the apple servers were overloaded with people trying to upload photos and connect to facebook. Then i got the message (U.S. members are not allowed to connect at this time) or something along those lines. Now its completely gone. I believe apple will get their servers up and running overnight and give the capability back to everyone in a day or two. For now, you will just have to live with twitter and facebook.

How does inactive connection timeout attribute in weblogic works ?

Lets say If there is a connection leakage in my application running on weblogic server 10.3.4 and I want to regain the unclosed connection.
After going through some documentation I found out that setting inactive connection timeout to a positive value can fix this issue.
With setting the above attribute will the weblogic server close any connection object which is inactive for specified number of seconds or it acts on only
those connection objects which has lost all the references to it ?
demonstrating the query by an example ,
Lets say I have two connection objects con1 & con2 taken from a defined datasource in the weblogic.
the inactive timeout has been set to 10 seconds.
In a given thread lets say con1 does some db operation and then after being done, con2 is used for another db operation for greater than 10 seconds.
Will the object con1 be still available for db operation or we need to take a fresh connection from the pool ?
Thanks,
Tarique
Edited by: user779368 on 30-May-2011 06:29

Any connection that has been reserved by an application, and not used for longer than
the inactive timeout limit, will be taken back by the pool. All it's sub-objects will be closed etc.
In your case, you would lose con1 while con2 was being used. Ideally, you would get
any/either of those connections at the instant you really need it. Then, ideally use it
till you can close it. But if you are doing transactions or a job that need connections,
but can't avoid having them idle for X seconds, then set your inactive timeout larger than X.

How does the connection with ODBC work exactly?

Hi all,
I've got an application written in Java that uses a JDBC-ODBC bridge to connect to an Oracle 8.0.5. Then i got another java application(called the bridge from here on) that only routes traffic to another server. Say that I connect to my bridge using sockets and my bridge is located on machine: remotehost port: 4444 and all my bridge does is reading incoming data and routes to machine: oracleserver port: 1521. This works fine. Now i have "fooled" my main application that my oracleserver is located om machine: remotehost port: 4444. So I can connect to it by DriverManager.getConnection("jdbc:odbc:tns-spec"); And in tns-spec I've stated that my oracleserver is in fact on port 4444. This works fine, but when I exit my bridge program the connection to the database is still there! Why? Does Oracle open a new socket of it's own and contacts my main application directly or what is happening?
Greatful for an answer is
Magnus

Think I've solved the problem, apperently oracle send data back, specifying on which port the data traffic should take. Say I contact Oracle machine remotehost port 1521 then I get a reply back, saying contact, remotehost port XXXX instead...Too bad...
