WebServices with BLOB IN params

Hi
I have managed to deploy DB procedures as native WebServices - great functionality!
I would like to do this with BLOB parameters passed IN to the procedure.
As the web service is XML based the BLOB must be cast (converted) to a character representation.
How to do this?
The procedure would be something like:
create_event(p_event_code IN varchar2,
p_event_date IN varchar2,
p_BLOB IN BLOB);
This would work in PLSQL but not as a web service.
How can I change the BLOB parameter to something that XML can represent?
Once I get the raw data in the procedure I can convert to a BLOB and insert into the table.
Any help would be appreciated.
Regards
Chris

Hi Chris!
Perhaps you could use the CONVERTTOCLOB and CONVERTTOBLOB procedures from the package DBMS_LOB, which convert from the binary representation of a BLOB type to character data in a CLOB or NCLOB type and viceversa.

Sergio

Develope complex WebService with JDeveloper and deploy to tomcat

Hello,
I am thinking of developing a complex WebService with JDeveloper and deploy it to tomcat.
The WebService should retrieve a few "normal" datatypes and a pdf and a few images. I try to store the pdf and the image in an Oracle DB as BLOB.
My idea ist to create a Package which selects the values, pdf and the image and retrieve them as the output paramter.
Then I want to create a WebService with the JDeveloper which calls this Package. This WebService should be published on a Tomcat.
My first question is if that is possible?
I think there are few problems.
I searched the forum about deploying a JDeveloper WebService to Tomcat, but I can not find a whole solution which is going to work. I read something about JAX-RPC, but I am new to this topic. So it would be very nice, if anyone could tell me where I can find the solution or post a quick guide to solve that.
Another question is how I have to decode the images and the pdf to provide those files in a WebService?
I would be very glad if anyone can help me or tell me where I can find information about that, becaus I am new to this topic!
Thank you,
Tim

Hi,
does anybody have an idea about that?
Thanks,

Error while importing a table with BLOB column

Hi,
I am having a table with BLOB column. When I export such a table it gets exported correctly, but when I import the same in different schema having different tablespace it throws error

What can I do so that this table gets imported correctly?
Also tell me "whether the BLOB is stored in different tablespace than the default tablespace of the user?"
Thanks in advance.

Hello,
U can either
1) create a tablespace with the same name in destination where you are trying to import.
2) get the ddl of the table, modify the tablespace name to reflect the existing tablespace name in destination and run the ddl in the destination database, and run your import command with option ignore=y--> which will ignore all the create errors.

Problem when adding ABAP custom webservice with Visual Studio 2010

Hi All,
After creating a webservice for a custom RFC function developed in a ECC6.0 SAP machine, I tried to add it to a Visual Studio 2010 windows aplication (through a web reference connection).
The sequence I've done is:
- Create RFC in ABAP, with testing ok
- Create a WEBSERVICE with the ABAP editor
- Configured the webservice with SICF with:
     Procedure: Standard
     Logon data: standard R3 user
     Security requirement: Standard
     Authentication: Standard SAP User
Then, in SOAMANAGER I copied the webservice URL and tried to add it to Visual Studio 2010, but it keeps asking me the user and password. I try to supply the R3 username and password but if fails.
Why is ECC6.0 asking the user and passord if I've defined a SAP user for the login process?
Is there any way to disable this?
Thanks,
Manuel Dias

Hello Manuel,
You can use the following code:
CredentialCache cache = new CredentialCache();
      cache.Add(new Uri("WEBSERVICEURL:PORTNUMBER/"), "Basic", new NetworkCredential("USERNAME", "PASSWORD"));
SAP needs a password.
Kind regards,
JK

Sample insert into table with BLOB column

This is my first opportunity to work with BLOB columns. I was wondering if anyone had some sample code that shows the loading of a blob column and inserted into the table with a blob column.
I have to produce a report (including crlf) and place it into a blob column. The user will download the report at a later time.
Any suggestions / code samples are greatly appreciated!!!!

You can enable string binding in TopLink.
login.useStringBinding(int size);
or you could enable binding in general,
login.bindAllParameters();

Hi!
Thanks for the help:
- I give all proxy details. In HTTP and HTTPS proxy tabs too.
one interesting thing:
- We publicate the same WebService with HTTP and HTTPS prefix.
- If I create a proxy for the WS with HTTP, everything is correct and works well.
- If I create a proxy for the WS with HTTPS, gives the error written the previous posts. (And can't create the logical port with SOAMANAGER)
I compare the 2 WSDL. It is the same, except the links. (HTTP and HTTPS) all others are same.
- And why it is possible in both case (HTTP, HTTPS) to create the proxy with SE80 from the WSDL URL? (And after the logical port was failed)

Help with Consuming a Webservice with the compact framework

Hi all,
i want to consume a SAP WebService within .NET in a smart device application. When I create the proxy, I get the following procedure in the .cs class:
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://www.sap.com/_-ICO_-CM_XML_CREATE", RequestElementName="_-ICO_-CM_XML_CREATE", RequestNamespace="urn:sap-com:document:sap:rfc:functions", ResponseElementName="_-ICO_-CM_XML_CREATE.Response", ResponseNamespace="urn:sap-com:document:sap:rfc:functions", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)][return: System.Xml.Serialization.XmlElementAttribute("SUBRC", Form=System.Xml.Schema.XmlSchemaForm.Unqualified)]public string ICOCM_XML_CREATE([System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] string ORDERNR, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] string ROUTE, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] string TESTRUN, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] string TOURNO, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] string XML_FILE_LOCAL, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] string XML_FILE_SERVER, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] out string XML_STRING) {object[] results = this.Invoke("_ICO_CM_XML_CREATE", new object[] {ORDERNR,ROUTE,TESTRUN,TOURNO,XML_FILE_LOCAL,XML_FILE_SERVER});XML_STRING = ((string)(results[1]));return ((string)(results[0]));}
When I compile the project I get the follwing error for each occurance of the "Form" Attribute :
"'System.Xml.Serialization.XmlElementAttribute' does not contain a definition for 'Form'" 
When I try to consume this webservice with a "normal" kind of application, such as a windows-application, everything is ok.
But when trying to use it with the compact framework, the error occurs.
Is anyone outhere who can help me?
Thank you
Regardings

It seems that the "Form" property of the XmlElementAttribute was missing in Compact Framework 1.1. It does exist in Compact Framework 2.0.
You can try removing the "Form=System.Xml.Schema.XmlSchemaForm.Unqualified" entries from the proxy, but I'm not sure of it will still correctly work: For in-parameter it should be Ok to skip "Form=", but for out-paramters and result it could have the effect that no data is received.
In this case the best option may be to upgrade to Compact Framework 2.0.

How integrate azure media services with blob storage?

I need to upload lots of content over blob storage which contains different types of files.
Now my problem is that files contains lots of videos also.
I want to way by which i can integrate azure media services with blob storage so that i can stream that video.
So probably i don't want to upload my videos on azure media services storage because i want all my content to be at one place which is blob storage.
Is there any way to achieve this?
Thanks,

Hi Rajesh
Every Media Services account needs a blob storage account associated with it. You can choose an existing blob storage account for that purpose. In order for Media Services to work with your videos you need to create an asset using the Media Services APIs.
That call results in the creation of a container which has the name in the following format asset-<AssetId>. The actual video files need to go as blobs within this container but these files need to be known to Media Services and you can do so by adding
AssetFiles to the asset using the Media Services APIs. Once you do that the asset is well known to Media Services and you can stream it.

WebService with multiple methods

Hello to everybody.
I need an help with the develop of a WebService that it comes with 2 methods: I have already created a lot of WebService in JCAPS6 with only one method and everything was gone well. I tried to implement a WebService with 2 or more method but when I tried to deploy the project I always received this error message: "Deploying application in domain failed; Deployment descriptor file META-INF/application.xml in archive [nameOfArchive]. Duplicate unique value [element] declared for identity constraint of element "application"."
Theese are the steps that I have done:
1) create an XSD for Input message
2) create an XSD for Output message
3) create a WebServiceDefinition with 2 methods "Method1" and "Method2" and all message (input/output) implemented
4) create a BusinessProcess (bp1) to implement Method1 operation
5) create a BusinessProcess (bp2) to implement Method2 operation
6) create a Connectivity map whith "bp1" and "bp2" directly connected with a new "Web Service External Application"
7) create a deployment profile
The "Build" operation was gone well but the "Deploy" operation always returned me an exception.
What can I do to develop this type of WebService?
Anyone can help me?
Thank you in advance.
Best regards,
Marco Tranquillin

My collegue found a solution:
1) create WSDL with 2 or more operations (with input,output and fault messages);
2) drag & drop "Event Based Decision" element into Business Process;
3) link "Start" to "Event based decision";
4) link "Event based decision.end" to "End";
5) link a scope (with inside what you want) with "Event based decision";
6) choose your operation from WSDL and drag & drop it OVER the icon with the mail icon;
7) link operation.reply with the output scope and with the element "Event Based Decision.end";

Call a Webservice with SAML securty in PI 7.0

Hi experts,
I need to call a Webservice with SAML security from PI 7.0, Is It possible? or only It is possible with PI 7.1?
Thanks in advance,
Jose Manuel

Hi Jose,
Let me answer your questuion first :
No, using PI 7.0 I dont think its posible..
Below is a brief overview on SAML.
SAML: It stands for Security Assertion Markup Language, it is an XML standard which is used to exchange security information between a service provider and an identity provider.
Why we need it ???
We have a concept called Principal Propagation in PI 7.1, Principal Propagation allows to securely pass the identity of a user from a sender application to a receiver application. There are various adapters and protocols which support the Principal Propagation and one protocol amongst them is the Webservice Reliable Messaging Protocol or WS-RM. Principal Propagation solution for WS-RM protocol is based on SAML and uses the SAML assertions.
There are some video recordings available for configuration and you can view the same as below,
Configure a Trust Relationship between Sender and Integration Server: Exchange sender's digital certificate between sender and Integration Server.
Configure Trusted Issuer: Map user in the Integration Server, and specify issuer. Default issuer is the sender's system ID, default attester is the sender's certificate.
Configure Sender Agreement and Sender Communication Channel: In Integration Directory, select SAML Sender Vouches Assertion as authentication method.

Html email with blob attachment and authentication

I have been looking for a plsql package to send html emails with blob attachments. The html portion and the blob attachment are more than 32k.
Also the email server needs to be authenticated.
Does anyone know of something already written to do this? I’ve found lots of code that does one or two items but not all.
Must:
- Authenticate
- Html email
- Accept blob as input parameter for attachment
- Exceed 32k
There are so many routines, I’ve been searching looking for one which does all.

This works for authentication:
utl_smtp.command(l_mail_conn, 'AUTH LOGIN' );
utl_smtp.command(l_mail_conn,utl_raw.cast_to_varchar2(utl_encode.base64_encode(utl_raw.cast_to_raw ( v_username ))));
utl_smtp.command(l_mail_conn,utl_raw.cast_to_varchar2(utl_encode.base64_encode(utl_raw.cast_to_raw ( v_password ))));

Jdeveloper 11g : Generating webservices with streaming attachments support

Hi,
We are trying to create a Java Webservice with support for streaming attachments. In 10g we are using the Attachments API from the oracle.webservices.attachments package.
In Jdev 10g we were doing it the following way:
public String getXMLFile(String name,String fileName,Attachments atts) throws RemoteException
try
AttachmentFactory factory = AttachmentFactory.newInstance();
Attachment imageAtt = factory.createAttachment(fileName, "text/plain", new FileInputStream(fileName));
atts.getOutgoingAttachments().addAttachment(imageAtt);
} catch (Exception e) {
System.out.println(e.getMessage());
return "Hello " + name;
This webservice is deployed in Oracle AS.
How do we do it in Jdev 11g and we want to deploy the service in WLS 10.1.3. If we try to create a webservice over this class in Jdev 11g we get the error :"no-arg default constructor not present".
Any pointers would be highly appreciated.
Thanks and Regards,
Pritom

Hi Vishal,

Problem with BLOB data type and acute characters

Hi all, I have an issue related with BLOBS cols:
I have table A with a BLOB column and I need to insert that data into another table B, the thing is I use dbms_lob.read() that returns data into a RAW variable and then I convert it to a varchar2(with utl_raw.cast_to_varchar2) and it works ok if I have no "acute characters" on it, e.g Québec.
If I have acute characters, the "é" is inserted wrongly with an "¿" character on the table B. I tested the BLOB on the table A to check the data and the BLOB is showing correctly the "é" character, it seems that the dbms_lob.read() funct cannot handle accute characters and replace them with "¿".
How can I replace acute characters when I use the dbms_lob.read functionality?
Thank you!

what's the OS of the db server? is this code an anonymous pl/sql block, or stored pl/sql? does it run on the server or a client? if it's on the client, what's the o/s of the client?
