Bundled Web Services Package API?

Is there an API for the bundled Web Services Package in JSC 2?
I'm reading the Field Guide which give an example of using the Google Web services package. After you make the request it returns a GoogleSearchResult Object which you can easily grab data.
But, now I want to use the bundled Amazon package. How can I easily figure out the object type that all of these classes are returning?
I'm a beginner. I know this may be more a general Java question.

After adding the Web Service to the Web Services node, expand the added W/S and select the methods and look at the property sheet for details. Also you can right click on the method and select "test" and you'll see lots of detail about the W/S and its return object structure in the test dialog.

Securing DSP calls via Web Services Mediator API

I have been implementing a client of DSP 3.0 services using the static Web Services Mediator API. I am successfully calling these through the AL Service Bus, where I have deployed the WSDL generated from the DSP. We are calling this from a rich client (i.e. the client is not running in any container). My company has chosen to use SAML-based security on all web services deployed in the service bus.
I know how to use general-purpose web service clients to pass SAML tokens to the web service. My question is, how do I do this when using the Web Services Mediator API. I have noticed the XMLHelper class and the RequestConfig class, but I have not seen much in the way of examples of using them.
Related question:
Is it possible to insert additional content into the SOAPHeader, or configure attributes on the Port?
Thanks,

I'm checking into the SAML question.
Regarding the soap header - whatever is in the contract defined in the WSDL.

Can't install Microsoft Exchange Web Services Managed API 2.0 - message says it is already installed but it is not.

I tried to install the Microsoft Exchange Web Services Managed API 2.0 but I got a message saying it was already installed and that I should un-install it. However it does not appear in the control panel un-install a program list. I am using
VS2013 on windows 8. What can I do to get it to work?

Fetching all mails in Inbox from Exchange Web Services Managed API and storing them as a .eml files

I want to fetch all mails in the Inbox folder using EWS Managed API and store them as .eml.
I can store file once I get the file content as a byte[] will
not be difficult, as I can do:
File.WriteAllBytes("c:\\mails\\"+mail.Subject+".eml",content);
The problem will be to fetch (1) all mails with (2)
all headers (like from, to, subject) (I am keeping information of those values of from, to and
other properties somewhere else, so I need them too) and (3)byte[]
EmailMessage.MimeContent.Content. Actually I am lacking understanding of
Microsoft.Exchange.WebServices.Data.ItemView,
Microsoft.Exchange.WebServices.Data.BasePropertySet and
Microsoft.Exchange.WebServices.Data.ItemSchema
thats why I am finding it difficult.
My primary code is:
When I create PropertySet as
follows:
PropertySet properties = new PropertySet(BasePropertySet.FirstClassProperties, ItemSchema.MimeContent);
I get following exception:
The property MimeContent can't be used in FindItem requests.
I dont understand
(Q1) What these ItemSchema and BasePropertySet are
(Q2) And how we are supposed to use them
So I removed ItemSchema.MimeContent:
PropertySet properties = new PropertySet(BasePropertySet.FirstClassProperties);
I wrote simple following code to get all mails in inbox:
ItemView view = new ItemView(50);
view.PropertySet = properties;
FindItemsResults<Item> findResults;
List<EmailMessage> emails = new List<EmailMessage>();
do
findResults = service.FindItems(WellKnownFolderName.Inbox, view);
foreach (var item in findResults.Items)
emails.Add((EmailMessage)item);
Console.WriteLine("Loop");
view.Offset = 50;
while (findResults.MoreAvailable);
Above I kept page size of ItemView to
50, to retrieve no more than 50 mails at a time, and then offsetting it by 50 to get next 50 mails if there are any. However it goes in infinite loop and continuously prints Loop on
console. So I must be understanding pagesize and offset wrong.
I want to understand
(Q3) what pagesize, offset and offsetbasepoint in ItemView constructor
means
(Q4) how they behave and
(Q5) how to use them to retrieve all mails in the inbox
I didnt found any article online nicely explaining these but just giving code samples. Will appreciate question-wise explanation despite it may turn long.

1) With FindItems it will only return a subset of Item properties see
http://msdn.microsoft.com/en-us/library/bb508824(v=exchg.80).aspx for a list and explanation. To get the mime content you need to use a GetItem (or Load) I would suggest you read
http://blogs.msdn.com/b/exchangedev/archive/2010/03/16/loading-properties-for-multiple-items-with-one-call-to-exchange-web-services.aspx which also covers of paging as well.
3) offset is from the base your setting the offset to 50 each time which means your only going to get the 50 items from the offset of 50 which just creates an infinite loop. You should use
view.Offset
= +50;
to increment the Offset although it safer to use
view.Offset += findResults.Items.Count;
which increments the offset based on the result of the last FindItems operation.
5) try something like
ItemView iv = new ItemView(100, 0);
FindItemsResults<Item> firesults = null;
PropertySet psPropSet = new PropertySet(BasePropertySet.IdOnly);
iv.PropertySet = psPropSet;
PropertySet itItemPropSet = new PropertySet(BasePropertySet.IdOnly) { ItemSchema.MimeContent, ItemSchema.Subject, EmailMessageSchema.From };
do
firesults = service.FindItems(WellKnownFolderName.Inbox, iv);
service.LoadPropertiesForItems(firesults.Items, itItemPropSet);
foreach(Item itItem in firesults){
Object MimeContent = null;
if(itItem.TryGetProperty(ItemSchema.MimeContent,out MimeContent)){
Console.WriteLine("Processing : " + itItem.Subject);
iv.Offset += firesults.Items.Count;
} while (firesults.MoreAvailable);
Cheers
Glen
.Offset += fiFitems.Items.Count;

Does OVM 3.0x provides management web service or API?

Hi
I thought OVM 2.20 provided Oracle VM Manager Web Services API Reference.
Where can we find the same thing for OVM 3.0x?
Thanks.

EJB Web Services Packaging and Deployment

I am new to Web Services on WebLogic as all my experience of Web Services have been on Apache Axis. My first question that I have an EJB that I would like to expose some of it's methods via a Web Service but the EJB is a part of an already deployed, or at least it's an external EJB of an existing app, how do I package and deploy my web service so that it interacts with the EJB properly but doesn't have to modify the existing application? Thanks, Jeremy

Hello,
Which version of EJB are you using? (EJB3 or 2.x)
If you are using EJB3 you can directly expose your EJB as WS using annotations see the EJB3 page.
The the binding coule be done with a simple java Proxy or a @WebServiceRef resource reference to a Java class.
Are you using ADF ?
If you are using ADF, the binding of the data source that could be an EJB or a Web Service is declarative using a data control

Unable to deploy a war(includes web services)packaged into EAR on jboss 5.0

I am new to web services and wanted to develop one
I used the following softwares / IDE
Eclipse 3.4.2
Apache Ant 1.7
Jboss AS 5.0.1
JBoss ws 2.0
jbossws-native-bin-dist 3.2.1GA
sun jdk 1.6.0_12
So i started off quite well configuring all that is required to create a web service
i took the help of eclipse ide tools like create web service and create web service clients.
when i created the web project in eclipse i selected the option add project to ear.
and finally i start the jboss server with in eclipse and add project the ear file that contains the war file.
just when i thought all is fine the server throws an error
13:01:52,929 ERROR [AbstractKernelController] Error installing to Real: name=vfsfile:/C:/jboss-5.0.1.GA/server/all/deploy/TempWsEAR.ear/ state=PreReal mode=Manual requiredState=Real
org.jboss.deployers.spi.DeploymentException: Error during deploy: vfsfile:/C:/jboss-5.0.1.GA/server/all/deploy/TempWsEAR.ear/TempWs.war/
I have searched jira to find a solution for this , but i think i couldnt find an appropriate solution
I am not sure if the search critirea i entered was close to the issue.
The log pasted below is the one when i start jboss from with in eclipse .

When you say:
I then copied the 10.1.3 Standalone OC4J to the Solaris 5.9 box which already has JDK 1.5 Update 12 installed. We extracted the OC4J to its own directory , set the Java_Home and the Oracle_Home environment variables and were able to
startup the OC4J instance.
We had some issues when extracting OC4J to its directory but there were no errors displayed on the screen ... Only when we tried starting up the OC4J instance , it started complaining about missing XML files .. This was resolved by manually extracting the XML's from the corresponding jars and placing them in the proper directories ..
It sounds like you have some funky issues there with those missing XML files -- that is not expected or normal.
Do you mean you copied the same oc4j_extended.zip to the server and unzipped it, or you zipped up the directories you were using on the Windows box, copied that over, and unzipped it?
I don't know of any problems with Solaris, JDK5, U12.
What about if you do this to remove any issues with the remote copy aspect of the deployment.
1. Stop OC4J.
2. Manually copy CISS.ear to /home/aplperdev1/ssp_java/oc4j/j2ee/home/applications/
3. Edit the j2ee/home/config/server.xml file and add the entry to deploy the application
4. Edit the j2ee/home/config/default-web-site.xml and bind any web-modules you need.
5. Start the server and see what happens -- the application should be deployed.
Also, what happens if you use the $JAVA_HOME/bin/jar to try and view the contents of the CISS.ear file?

Web Services Managed API

Hey,
I'm trying to expose some Exchange stuff through my .NET web site. It's not working because I want to use the logged in users credentials but this fails. If I hard code a username and password all is well.
My setup is:
Client > IIS 7.5 Server > Exchange 2010 Server
I know it's to do with Kerberos, but I cannot figure out where it's failing. I've setup SPNs on the Exchange server, and enable delegation on the IIS computer account in AD.
I have this working perfectly for IIS Server > SQL Server using a domain service account for SQL, so Kerberos itself appears to be sound. Same Web site, same IIS Server I'm trying to use for Exchange Web Services.
public void SendEmail_Click(object sender, EventArgs e)
try
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
service.UseDefaultCredentials = true;
service.AutodiscoverUrl("[email protected]");
EmailMessage message = new EmailMessage(service);
message.Subject = EmailSub_TextBox.Text;
message.Body = EmailBod_TextBox.Text;
message.ToRecipients.Add(EmailTo_TextBox.Text);
message.Attachments.AddFileAttachment(String.Format("{0}", FileName), Server.MapPath(String.Format("{0}", FileUrl)));
message.Save();
message.SendAndSaveCopy();
catch (Exception ex)
Info_Label.Text += String.Concat(ex.Message.ToString(), "<br />");
Info_Label.Visible = true;
This returns this error, when for example sending an email (as per above code):
When making a request as an account that does not have a mailbox, you must specify the mailbox primary SMTP address for any distinguished folder Ids.
The message sender (me) does have a valid mailbox!
Thanks.
PS: I have a single server Exchange environment.

Thanks Glen.
Will do. If I get anything from the IIS forum I'll post back here, in case anyone stumbles across it.
One final question: what, in reality, is the difference between these:
service.UseDefaultCredentials = true;
service.Credentials = CredentialCache.DefaultNetworkCredentials;
As they both work.

Exchange Web Service Managed API not authorizing

I find it very strange that I am able to create appointments in my calendar on our company's exchange 2010 server
using the asp.net 4.0 web application running on my XP machine which is not even part of the domain!, BUT when I upload the same code to our company's production Web application server
(which is not same as the Exchange server), then I get the error as follows:
System.Net.WebException: The remote server returned an error: (401) Unauthorized
I am using Window's authentication throughout. Using service.UseDefaultCredentials = true; I just cannot
afford to use the username/paasword for every staff who will be using this application. I am thinking there is some problem (rights/permissions/disabled impersonation) issue at the production Web application server (Windows 2008 m/c). I even played with the
Application pool identity in IIS 7 by selecting all the builtin accounts it can possibly run under, but same error. I can clearly see that it is running under my Windows account right before the Appointment.Save() call
is made. I am briefly impersonating using the logged in user's credentials and then removing the impersonation. I saw this technique elsewhere. But that doesn't make any difference either.

ConversationId property vs ConversationIndex property in Exchange Web Services managed API

EWS Managed API have two properties:ConversaionId and ConversationIndex
What is the difference between them? I guess ConversationId is
the the ConversationIndex of
the first mail in the conversation which is essentially of 22 bytes, while ConversationIndex is
the index of that particular reply in the conversation thread, essentially of 22 bytes + multiples of 5 bytes for each reply in the conversation. Is it like that?
Also ConversationId is
accessible only with Exchange Server 2010 onwards. So cant we access ConversationId in
the Exchange Server 2007?

I just found this thread that indicates that you can use an extended property definition to access the ConversationId in Exchange 2007. Very smart!
http://stackoverflow.com/questions/7487570/implementing-outlook-2010s-group-by-conversation-using-ews-and-exchange-2007
Henning's answer:
You can fetch the ConversationId and the ConversationIndex via extended properties:
private static readonly ExtendedPropertyDefinition ConversationIdProperty = new ExtendedPropertyDefinition(0x3013, MapiPropertyType.Binary);
private static readonly ExtendedPropertyDefinition ConversationIndexProperty = new ExtendedPropertyDefinition(0x0071, MapiPropertyType.Binary);
var items = service.FindItems(WellKnownFolderName.Inbox, new ItemView(512) { PropertySet = new PropertySet(BasePropertySet.FirstClassProperties,
ConversationIdProperty, ConversationIndexProperty)});
Both are binary properties. Their content is described in great detail here:
[MS-OXOMSG]: E-Mail Object Protocol Specification, section 2.2.1.2 and 2.2.1.3.
The properties themselves are defined in
[MS-OXPROPS]: Exchange Server Protocols Master Property List.

Silverlight enabled Web service package deployment

I'm programming Silverlight app and it uses a Silverlight-enabled WCF service to send email using EWS. It created XAP
package and deployed to Sharepoint. It works on my local machine but it doesn't work after deployment. What are the steps involved for the deployment. Does this XAP package includes WCF service? Do I have to deploy WCF service separately? Please let me
know if there are any suggestions. I am using Sharepoint 2010, Silverlight 5 and .NET 4.0.

Outbound TLS web services from api gateway

Hello,
We want to call a webservice with TLS 1.1. OR 1.2 from the api gateway.
This is the error i get:
transient failure connecting to remote: peer disconnected unexpectedly.

Hi,
I will assuming you actually mean TLS and not LTS.
If you want to use a specific Cipher you have to specify a custom list in your connection filter in the Ciphers field instead of DEFAULT.
List of ciphers: https://www.openssl.org/docs/apps/ciphers.html
Example in this screenshot.
Another common reason for the specific error message you don't have a CA Certificate in your certificate store for the endpoint you are trying to establish a connection to.
Cheers,
Stefan

Best Way to Expose our JAVA API as web service

we have develop an API and now, we want these API available as web services. the API abstracts the developer from database connection and the developer has to only concern himself of the object model. our problem with this API is that if we distribute this to our co-developers, their applications will be connecting directly to our database. but if we have this as a webservice, the connections to the databse will be isolated between the host that's running the webservice and the database.
what's the best way to move these API/objects to webservices? what are our options?
thanks,

You can pretty much put anything you want into a web service. But remember they are designed for network/internet calls so it might make sense to bulk wrap your API calls. Due to the large amount of XML that is required by a web service if your API is large and you will have many webservices you probably want to get a tool that can generate this for you.

Bundled Web Services Package API?
