Calling service from another classloading

Hello!
I have client and service classes residing in the same jvm (let's say in same container to be clear).
Client code call service. I want to separate classloaders that load client and service classes, and client code passed arguments to service by value, not by reference. Something like local ejb, but more lightweight.
Right now i'm out of ideas how to do this.
Any ideas, guys?
Thank you!

create a standalone proxy for your WSDL of the web service deployed on XI java stack and use its API library in the caller Web service...

Invoking one web service from another web service

Hi there,
I want to invoke a web service lets say X. But befor sending parameters to this web service, what i want to do is first pass the parameters to a web service called Y and Y will decide wether to call X or not. In other words i want to invoke a web service from another web service.
Its kind of urget so do the needful asap.
Thanks

Calling another webservice from within a webservice does not require anything special. The service (say svc1) that calls another service (svc2) will be a web svc client. So you will have to do the same steps for svc1 as you would do for any other web service client

Is it possible to call methods from another class from within an abstract c

Is it possible to call methods from another class from within an abstract class ?

I found an example in teh JDK 131 JFC that may help you. I t is using swing interface and JTable
If you can not use Swing, then you may want to do digging or try out with the idea presented here in example 3
Notice that one should refine the abstract table model and you may want to create a method for something like
public Object getValuesAtRow(int row) { return data[row;}
to give the desired row and leave the method for
getValuesAt alone for getting valued of particaular row and column.
So Once you got the seelcted row index, idxSelctd, from your table
you can get the row or set the row in your table model
public TableExample3() {
JFrame frame = new JFrame("Table");
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}});
// Take the dummy data from SwingSet.
final String[] names = {"First Name", "Last Name", "Favorite Color",
"Favorite Number", "Vegetarian"};
final Object[][] data = {
     {"Mark", "Andrews", "Red", new Integer(2), new Boolean(true)},
     {"Tom", "Ball", "Blue", new Integer(99), new Boolean(false)},

We have a 5s active on our account. After turning on a previously active 4s (it had the same number) The 5s can no longer place call and when you call it from another phone the 4s rings, but will not pick up. Texting over the cell networks works fine.

hens0861,
Hmm, let's ensure this is working as it should be! So what phone should be active on your account? Did you switch the devices online or how to did you activate the 5s? Please share details.

Calling one WTC service from another WTC service

Hi,
We have a service called COLLECT defined in our WTC server.
Recently we've added a second service called SUM in the same WTC server.
We were wondering if it's possible to call SUM from COLLECT, and if it is, what configuration changes should be made in order to do it?
Currently both services are exported by the WTC server (and imported by our Tuxedo).
Thanks,
Shy

Hi Shy,
Although I haven't tried it, I'm fairly certain you cannot call a Tuxedo EJB using tpcall() within a WTC based application. What I normally advise customers to do when writing a Tuxedo EJB is to implement two separate interfaces. One is obviously the TuxedoService interface that all Tuxedo EJBs must implement. In particular you must implement the service() method that accepts a TPServiceInformation instance that provides access to the typed buffer passed to the EJB. Normally one then extracts the necessary fields or information from the typed buffer, performs whatever necessary business logic needs to be performed, and then constructs a reply typed buffer.
What I recommend is that you separate out the business logic into a separate interface and have your class implement both interfaces. The service() method would only deal with the marshalling/unmarshalling of the information contained in the typed buffers, and leave all business processing to methods on the second interface. Then if you need to access another "service", you would use the second interface, thus saving you from all the typed buffer manipulation.
So in your case, the business logic in the second interface of the COLLECT implementation would simply call the SUM implementations second interface (the EJB's business logic) instead of trying to call a Tuxedo service. While this helps in reuse of the business logic, it doesn't address the issue of trying to transparently move a service implementation from say Tuxedo to WLS. If that's what you are trying to do, you might try exporting the SUM service from WTC to the Tuxedo domain gateway, and then importing the SUM service from that gateway. This would likely cause a network round trip if it works, but it's something to consider.
Another alternative is to use something like the Apache Tuscany/Java project and build your Java applications using SCA. Tuxedo SALT includes a Tuscany/Java binding extension that allows Tuscany/Java applications to transparently call Tuxedo services. The choice of whether to actually call a Tuxedo service or call a Tuscany/Java based SCA service is determine by the binding selection and not changes in your code. Just a thought...

Calling a Web Service from another Web Service

Hello,
I have the following scenario: Web Service -> XI -> RFC.
I have created the XI -> RFC configurations in the XI and exposed them as a Web Service. I tested the generated WSDL with WebDynpro for Java and it works well (I also uploaded the WSDL to the XI server and tested it from the wsnavigator).
I have created a Web Service from a Java class, deployed it on the XI server (the same XI server as the one with the RFC scenario), tested it and it works well.
Now I want to call the service I exposed from the XI from inside my Web Service.
How can I do that? Are there any code samples for that? I searched and couldn't find any.

Calling java web service from another webservice app

Hi,
I am newbie to writing java webservices and also new to weblogic workshop environment. Our company already has an web-service application (not written by me) that basically receives soap messages M1(e.g. with fields A,B and C) and does a function. The format of the message is defined in .xsd file and the application also has .wsdl and .jws file.
The modification now required is that this existing application will keep listening in port p1, but another copy of the same application will run in port p2. So i have to write a webservice code in weblogic workshop that basically recives message M1 and forward the message to port p1 or p2 depending upon field A=0 or 1.
Message M1 ---->New Application
|->forward to application running on port p1 if field A=0 in message M1
OR
Message M1 ---->New Application
|->forward to application running on port p2 if field A=1 in message M1
Please give me some example code/suggestions that i can start with. i am already starting to get a bit worried because i have to finish it in next 3 days and i don't have much experience with it.

Hi Gianluca,
here there is a little sample to implement a web service Proxy class that invokes a service from a Descriptor file.
http://help.sap.com/saphelp_nw04/helpdata/en/6c/8aac34d2d6e64dbcfc3ffb10bb3e9e/frameset.htm
Take care with SAP WebAS (Soap Runtime) and Apache Web Server. If the web Service is published on AXIS 1.0, SAP Soap ABAP runtime and AXIS 1.0 Soap Runtime aren't compliant.
You could migrate the Java application from AXIS 1.0 to AXIS 2.0.
If you need, don't hesitate to contact me!

ALSB-calling proxy from another proxy

hello,
I am calling a proxy service by another proxy service which is listening to JMS queue. The called proxy service is used to invoke a busiiness service.
I am using tcpmon for testing purpose. If i removed the second proxy and then put a message to JMS it's invoking my business service but if i add the second proxy i am not getting any output.
For second proxy i am using local transport. Might be the configuration i am giving is not able to pass the message to second proxy.
I searched a lot but could found anything sustantial !
Could anybody please help.
Thanks & Regards,
Aruna

If you don't have this yet, put an error handler on the first proxy, at the top level. Log $fault in the error-handling stage. See if you get any good information in the logs. You probably also want to add logging in your second proxy, an entry first thing in the request pipeline, and log $fault in an error-handling stage.
You should be able to get some kind of hints from the information that gets logged when you do that.

Getting "Origin is not allowed" When Trying to Invoke RESTful Service from Another Domain

I am having problems trying to invoke my RESTful web service from a different domain. I'm well aware of the normal restrictions of cross-site / cross-domain scripting but in Oracle documentation it says that all origins are allowed by default when creating a RESTful service without using authentication.
I have created a very simple service and am trying to invoke it using jQuery.Ajax calls from a different domain and I am getting XMLHttpRequest cannot load http://address_to_my_web_service. Origin http://calling_from_address is not allowed by Access-Control-Allow-Origin.
I understand that using JSONP instead of JSON is actually the best practice around cross-site scripting but it appears as though APEX does not support JSONP because with JSONP, there are URI parameters added to the base request (callback).
I am stuck and would greatly appreciate any help.
I'm starting to wonder if this could be a bug because Oracle documentation says all origins should be allowed when using a service that does not require authentication. I also tried to force the origin to be allowed by typing it in and also using the wildcard '*' and it still did not work.
Thanks,
Mark Williamson
EDIT: It is now working after adding a URI prefix to my web service module.

The SSL handshake works differently to a browser as it is making the connections automatically.
The browser asks every time if you want to trust an expired certificate, and it also recommends not to. Its impractical to manually check every service call to say do you trust the certificate so the functionality doesn't exist. I doubt any integration product does this. Therefore there isn't a option to ignore the certificate if it has expired.
This makes sence as the certificate is untrustworthy. The whole idea around SSL is trusting the site you are communicating with, all parties need to be trusted. This stops hackers from replicating their site and intercepting data.
If the administrator of the remote site is not willing to renew the certificate, are they really interested in SSL. I suggest they expose a non SSL service.
cheers

In Class B in implements actionlistener and when the roll button is clicked it should call "roll()" from Dice class
Dice d = new Dice();
d.roll();
it works but it does not repaint the graphics for the dice? the roll method will get a random number but then it will call the method to repaint()???

Delay in the Response Group Rining / Call Pickup from another Extension

Dear All,
We have just finished a deployment of Lync 2013 with Sonus 1000 as the Mediation Gateway, we have deloyed polycom VVX 600 phones,
We have two lines E1 and 5 Fxo lines (with same Pilot Number)
I would like the Receptionist to have both E1 DID number and FXO number and her phone to ring when the calls comes from DID line as well as FXO,
I have the below scenario
1) Currently the setup is that Receptionist is configured with the E.164 DID number : (Line URI is Tel:+971XXXX500;ext=500), which work perfectly fine
2) We have added receptionist in Response Group , and setting are (Formal,10 sec , Attendant)
The issue :
1) Call forwarding does not work on Response Group (which is by design it self)
2) When a call comes from the outside to FXO it goes to response group , (there is Music played and the ring on reception is delayed by 2-3 secs) ,
Customer does not want this delay , it should ring immediately with no music,
3) If the receptionist moves from one location to any other location to another , she should have the ability to remotely perform call forward to that extension by simply dialing few codes on the phone ( I already told customer
about PIN based authentication, by customer does like the idea of signing in or signing out)
In DIRE NEED OF HELP,
Regards,
Hasan Reza,

Hi,
Did the issue only happen for IP Phone in Response Group or also happen for Lync client in Response Group?
If the issue only happen for IP Phone, it seems to be an known issue. Please Make sure Lync Server update to the latest version and then test again.

How can i create proxy service from another proxy on different domain

i have a demo webservice. it has many operations on proxy service's message flow. How can i create proxy service from demo's wsdl on different domain
Edited by: fresh man on Jul 1, 2012 11:17 PM

You can either export the WSDL in a sbconfig.jar and then import this sbconfig.jar in the new domain. Then you can create a new Proxy in new domain based on the WSDL you imported.
Alternatively, you can open the WSDL in the old domain, copy the text content of WSDL, then open new domain sbconsole and create a new WSDL type resource and paste the content you copied from old domain WSDL here. Then you can create a new Proxy Service based on this WSDL resource you created.
Although, may I ask why do you need to create this new Proxy Service on a different domain? If you want to create a service similar to existing Proxy Service on different domain, then you can export the existing proxy service along with any dependencies to a sbconfig.jar and them import them in any other domain.
If you want your new Proxy Service to invoke the existing Proxy on different domain, then you need to create a Business Service in the new domain (calling domain) which can invoke your existing Proxy service in other domain.
