Newbie question about the viability of web services.

Hello All,
I have never dealt with web services, and have only cursory knowledge of the technology, so forgive my ignorance in advance.
I have a situation that I wonder if Web Services might help me solve.
I have built a Java/JSP application that resides on a server that is inside our firewall. It has been successful, and management wants to make the data and functionality available to our customers outside the firewall.
The problem is that our organization tightly controls the "public" applications. And the UI for my system does not meet their standards. Nor will they punch a hole in the firewall to allow access to my server.
The solution we have been working on is to create a new UI using their approved methods, and copy the needed java classes to the "public" server.
As you can see, if I do this, I will have to maintain two instances of the same class on two different servers.
Can I avoid this by using web services to make those classes available to other applications from my internal server?
Thanks in advance for your help.
James.

The solution we have been working on is to create a
new UI using their approved methods, and copy the
needed java classes to the "public" server.
As you can see, if I do this, I will have to maintain
two instances of the same class on two different
servers. Okay, first, yes - webservices can help you if you MUST maintain two seperate UI's for some reason using the same backend data code or if you want to provide a datafeed only to your external users. It will take care of having to maintain seperate but identical class files, but it will create other overhead such as interfacing the existing files and the like, but if you must enable the UI then you will have two versions of this to maintain. If you are looking to just enable the data feeds and not the UI then it would seem a very logical fit.
If you must maintain the UI, then why can't you convert your app over to the approved UI and host it on the "public" server for all users (internal and external)? Then you only have one set of data to maintain - period and webservices aren't necessary. If you proceed with either your current implementation or even with a webservices based implementation, you will have at least two seperate UI's to maintain as well as whatever the resulting support code - be it webservice interfaces to existing code or replicates of existing code - to also maintain.

Question about the distribution of web service or servlet

Hello,
I don not know how to distribute a web servcie or servlet on the web server. I can only use this web service with the open state of the glassfish. If I close the glassfish server, the servlet cannot be accessed.
I just want the web service or the servlet to be disributed on the web server. Web service and the servlet are available when the web server is on.

Quick questions on the topic of Web Services and EJB POJOs

I have been reading about Web Services and the data types that are aloud as operation parameters and return types. I was wondering what the standard practice for return types; is it to use the Entity classes straight and customize the WSDL instead of letting the EE container do it (avoid cyclic problems in the schema that can occur when using entity 1-to-many and many-to-1 mappings) or; is it to off load the data into a DTO/VO/Bean and let the EE container take care of all the schema mapping for the WSDL? I look at the EE tutorial and bought a EE book both use very basic examples that do not include connecting to a database or using EJB3 for the data store.
Thanks for any information

Short question about networking, Threads and web services..

Lets say I got 2 classes, Midlet A and Thread B.
I created Thread B because web services (jsr-172) uses networking and It has to be done in a separate thread other then the Midlet A.
So, in Thread B, I have the run(), where I do all my stuff, and some getSomething() methods.
I need to have run() complete before calling getSomething(), so I used something like this in Midlet A:
while(true){
if(b.isAlive())
getSomething();
}Problem is, Thread B only runs to completion when I don't call b.isAlive(). (I know from System.out.println I placed in it) When I do use any methods like wait() or join() or isAlive(), Thread B stops at the web service call.
I really don't understand what's the problem. I've tried various ways to only call getSomething() when the thread finishes running, but all of them made my WTK emulator hang at the part where it asks for permission to access the network.
If I don't use getSomething(), which is the purpose of starting the thread in the first place, it runs fine in the emulator and doesn't hang anywhere. Oh the irony.

Bump!
Anyone got even half a clue what's wrong? =O
Hmm. I think that having the midlet wait for the thread causes the midlet to hang because the thread will then wait for the midlet for permission to access the network, but the midlet is waiting for the thread to finish it's code. Damn.

Newbie question about the Zen Vision M, uploading D

If I want to put one of my DVD movies on the Zen, is this easy to do? How long does it take?

I'm afraid we cannot allow discussion on how to rip/copy protected DVDs.
I'll leave this thread open for now in case anyone has other (legal) information to add, but any information on ripping protected will be removed.

I want to question about the official service at the service center of Sony.
long since I like the models and items sony. from start playstation, cameras, camcorders up, I've ever had. and a new camera that I bought two years ie compact cameras Sony Cybershot DSC H200. as of a month ago, a camera was having problems in lenses that would not close. and setting the automatic mode to move by itself. I came to the Sony Service Center in Makassar, precisely on Jl. Shop Pengayomann A5 / 05 (0411) 442340.
operator initially said only two weeks to work on my camera. but this week has been more dau even want to go in a month tomorrow, dated July 9, no news from the service center. and I kept the call to the office service. as well as assorted reasons. there are no spare parts or technical constraints, and the last one I call to his office, he said the factory spare part is damaged. imported directly from Singapore. I think, ko new spare part it can be damaged before using that? how the quality of this Sony spare part? ugly? not good? why?
I was disappointed with this situation, where soon it will Eid, want to return home as well to Java. but the camera has not been settled workmanship?
nah, roughly what is the solution of the Sony plagued with this problem? please help, because he did not know to whom to complain. operator had just said: it's up to the father alone.
once again I asked for his help. solution. if you can before Eid arrived.
Thank you,

Dear Customer Service Team,
I bought a twelve-month Dreamweaver CC program with monthly payment that I have paid via bank transfer and there would be a question about the activation. How could I get the license key with which I can activate my account? I can not find it and now I only have access to the trial version.
Thank you for your help in advance.
Kind Regards,

SQL 2012 R2 - SSRS with the Report Server Web Service URL, can't access

Hello:
I am installing Dynamics CRM 2013. When I am on RS Configuration manager; I am running into the SSRS (SQL 2012 on Server 2012)SQL issue, can't access the
http://servername/:80/ReportsServer or
http://servername/:Reports web pages
The database server has SSRS native mode installed, it is using a domain account for the service credentials. This account also has permission to log on a service in the GPO
Account is a domain admin and is a local administrator
SQL server is 2012 R2 on Windows Server 2012. User base is less than 60 people and they have SharePoint 13 on the same SQL server. Server more than enough resources.
Any assistance would be appreciated.
Thanks..Dan

Hi DCas1,
According to your description, you could not access
http://servername/:80/ReportsServer or http://servername/:Reports web pages from Reporting Services configuration manager, SSRS in configured in native mode and the account you used is a local administrator.
In Reporting Services, URLs are used to access the Report Server Web service and Report Manager. Before we can use either application, we need to configure at least one URL each for the Web service and Report Manager. If we are using the Reporting Services
Configuration tool to create or modify the URLs, we can accept the default values for a URL or specify custom values. When we create a report server URL, we must specify the following parts: Host name, port and Virtual directory. In order to improve the efficiency
of troubleshooting, I need to ask several questions:
Since the default URL is http://<computername>/reportserver, did you type the URLs manually? or the URLs configured in Reporting Services configuration manager are
http://servername/:80/ReportServer and
http://servername/:Reports?
Could you provide detailed information of error log(default location: %programfiles%\Microsoft SQL Server\MSRS11.MSSQLSERVER\Reporting Services\LogFiles)?
For more information about Configuring a URL, please refer to the following documents:
http://msdn.microsoft.com/en-us/library/ms159261(v=sql.110).aspx

Question about the CSS behavior when using layer 3 sticky and sticky table

Hi everyone,
I have a question about the CSS behavior when using layer 3 sticky and sticky table is full.
If I configure layer 3 sticky and specify the inactivity timeout as below, how does the CSS
handle subsequent needed sticky requests ?
advanced-balance sticky-srcip
sticky-inact-timeout 30
CSS document says that
Note:
If you use the sticky-inact-timeout command to specify the inactivity timeout
period on a sticky connection, when the sticky table becomes full and none of
the entries have expired from the sticky table, the CSS rejects subsequent
needed sticky requests.
My question is what is the next reaction by doing the CSS if the CSS is in the
following condition:
when the sticky table becomes full and none of the entries have expired from
the sticky table, the CSS rejects subsequent needed sticky requests
Does CSS just rejects/drops subsequent needed sticky requests ?
or
Does CSS does not stick subsequence requests to particular service but CSS forward
subsequence requests with round-robin basis ? which means if the sticky table is full,
the CSS just works round-robin load balancing fashion for subsequence requests ?
Your information would be appreciated.
Best regards,

Hello,
There is a good document explaining this on Cisco web site
http://www.cisco.com/en/US/products/hw/contnetw/ps789/products_tech_note09186a0080094b4b.shtml
It depends if the sticky-inact-timeout is used or not. If not, it's FIFO (the oldest entry in the sticky table is removed). If yes, the CSS will reject the next sticky request.

Question about the order to creating Account, Contact, Contact Role

Hi, my friends,
I have some questions about the order of creating Account, Contact, Contact Role, etc in Web Service 1.0. I could create them in the following case:
1. Insert Contact object and get contactId (now new contact exists in CRMOD)
2. Insert Account object with Contact Role child associated with contactId
My questions are:
1. Do we have the following order? Insert new Account with new Contact child and Contact Role child (Contact is new and does not exist in CRMOD).
2. Looks like system need accountId, contactId, etc to make the objects relationship. Is there other field having the same function?
Thanks
Ray

Hi Ray,
In response to your questions:
1. Do we have the following order? Insert new Account with new Contact child and Contact Role child (Contact is new and does not exist in CRMOD).No. Both the Account and Contact must already exist. The Role value is an attribute on the Account Contact relationship, this relationship must exist in order to assign a role value to it. This is consistent with the behaviour of the UI, when you press the New button on the Contact child applet, you are taken to the Contact New page where you can create a Contact record. Once you save, the relationship is created but you cannot assign a role value unless you click the Edit Roles link next to the new Contact.
2. Looks like system need accountId, contactId, etc to make the objects relationship. Is there other field having the same function?Correct, the system needs to know which Account/Contact pair is being assigned a role value. To do this the Account and Contact values must be uniquely identified using the Id values for each.
I hope this helps.
Thanks,
Sean

Hi ,
No data will be lost either from your Windows program files or other drives as long as it is an upgrade.
After upgrade you will still be able to see your old program files under windows.ol folder in the C: Drive of the new OS.
The data will be lost only when you perform a clean install like complete formatting the HArd disk and installing from scratch.
As mentioned it always good to maintain a backup preferable important files in a skydrive as there is a good chance of external drives crashing.

How do I set up Mozilla to accept connections on port "The World Wide Web service (HTTP)"?

When attempting to embed a video in PowerPoint 2013, the message "Sorry we are having some temporary service issues" appears.
In researching the problem at Microsoft. com, the following message was received: Mozilla is not set up to accept connections on port "The World Wide Web service (HTTP)."

Hmm... PowerPoint should use Windows to connect to the internet and not Firefox.
Which method are you using?
(1) Insert > Video > Online Video
Apparently there was an update this month that enables this, as described in this support post (see top Answer just after the question): [http://answers.microsoft.com/en-us/office/forum/office_2013_release-powerpoint/embedding-online-you-tube-video-in-powerpoint-2013/0bc00dde-420c-4c6a-bd47-3fb105ce40fc Embedding online you tube video in powerpoint 2013 - Microsoft Community]
Here's how it should work after the update: [http://office.microsoft.com/en-us/powerpoint-help/insert-or-link-to-a-video-on-youtube-HA104192855.aspx Insert or link to a video on YouTube - PowerPoint]

In Java EE 7's Firstcup tutorial, why does does the web tier consume the data from the dukes-age web service?

In the Firstcup tutorial, the responsibilities of the web tier are listed as:
dynamically generate content for the client
collect input from the user
return results from business tier components
control the flow of client screens & pages
maintain session state
perform basic logic
hold data temporarily in JavaBeans components
Which of these responsibilities would retrieving data from a web service fall under?
The tutorial also lists the technologies used in the web tier, and JAX-RS is not included in that list. The list of technologies used by the business tier does, however, list JAX-RS. I was surprised to find the DukesBDay JavaBeans component (in the web tier) calling the dukes-age web service, instead of the DukesBirthdayBean EnterpriseBean (in the business tier), which uses hard coded value for Duke's birth date.
Is it typical for the web tier to consume web services in this way? What about when using an application client container, wouldn't that skip the web tier altogether, and in doing so also skip the web service call? Wouldn't DukesBirthdayBean in the business tier benefit from making the call to the web service, instead of having the date hard coded into it, and wouldn't this also solve the problem of the missing web service call when using an application client container?

Hi Shadab,
Here is a list of Web service standards supported by SAP in NetWeaver 7.1.1: [Supported Standards|http://help.sap.com/saphelp_nwpi711/helpdata/en/44/624479f7e608fae10000000a422035/frameset.htm] (also in [7.0|http://help.sap.com/saphelp_nw70/helpdata/EN/44/624479f7e608fae10000000a422035/frameset.htm] and [7.0.1|http://help.sap.com/saphelp_nw70ehp1/helpdata/EN/44/624479f7e608fae10000000a422035/frameset.htm]). The Enterprise Services adhere to these standards, and on the provider side you have the tools to configure the authentication settings as needed. On the consumer side, one just has to use a Java release (or any other platform) that supports these standards.
While I am not a Java developer, there should be [many ways to consume a Web service in Java|http://www.google.bg/search?q=consumewebservice+java].
Hope this helps,
Rossen

Question about the custom panel language

I have a question about the custom panel language...
The document you provide seems to lack details on some features. Namely the icon and picture widgets. I see from looking at the examples and other vendor's web pages that these features exist, but I don't find any detailed descriptions of them in the documentation. Is there a more complete document describing these and other features...
http://www.adobe.com/products/xmp/custompanel.html
Alternatively, can someone fill me in on the syntax and options for at least the icon and picture widget. For instance, how do you load external icons or pictures...
Tom

Gunar,
It could be interesting to have something like
icon(url: 'http://www.adobe.com/Images/logo.gif', width: 20, height: 20);
or better
picture(url: 'http://www.adobe.com/Images/logo.gif', width: 20, height: 20);
for the pictures and
include(url: 'http://www.adobe.com/xml/custompanel/camera1.txt');
for include the cusmtom panel's dynamic portions
