Efficient access to database from web services

Hi
I'm implementing a web service interface to a database. The interface allows its clients to perform a series of independent operations which change some values in a database. Each of these operations is an independent web service, but all of them use the same database.
My first approach was to make each service completely self-contained, and have it create its own JDBC connection to access the database. However this doesn't sound very efficient.
I mean, isn't the application server there precisely to provide these types of services to the applications it hosts? So, is it possible to have it manage a pool of connections of some kind and make the web services get their connections from that pool?
Thanks in advance
Pedro

Hi Cemal,
Try the following.
IWDClientUser user = WDClientUser.getCurrentUser();
user.getSAPUser().getUniqueName();
Please check old postings in the forum.

ClassNotFound Error while accessing Shared Libarary from Web Service WAR

Hi All,
I have developed a JAX-WS based Web Service(WAR file) using Jdeveloper 11g and deployed it to Web Logic 10.3.4 server. My web service requires access to a shared library(a JAR file ) which is already deployed on the server. So, I had modified the MANIFEST.MF file to have the reference to shared library as a
optional package(since my web service is WAR) as below.
Manifest-Version: 1.0
Extension-List: bizlib
bizlib-Extension-Name: biz_lib
bizlib-Implementation-Version: Oracle Version 1.1
The biz_lib is the Name of the library as seen in the Deployments section of the Web Logic Admin Console. Since there is no extension name given explicitly in the MANIFEST file of shared library, I have mentioned the name as seen in the deployments for the library. After deploying my WAR, when I go into the details of the Shared Library - biz_lib, the Admin console shows my web Service as part of - "Applications that reference this Library" section. So, I presume that my Manifest is correct. But when I test my web service from Admin Console, I face - java.lang.NoClassDefFoundError. The class that is pointed out as part of the error is part of the referenced Shared Library - biz_lib ( part of a JAR file that is listed in the Class-Path: section of shared library’s MANIFEST file). My Web Application is unable to find the class files in the shared library. Please help me. Please let me know any further information is required.

          I am not sure if this helps. I encountered a similar problem and
          finally resolved it. Initially I got the error 500 - Internal
          Server error, and was not able to access my servlet which I deployed
          using .war file.
          We should make sure that the directory structure under
          WEB-INF/classes directory should reflect the package that
          your servlet belongs to. I had a HelloWorld servlet with
          the statement "package examples.servlets;" on the first line.
          So after compiling this servlet, the HelloWorld.class file
          should be copied into WEB-INF/classes/examples/servlets directory
          and not into WEB-INF/classes directory. After making this change,
          I made a new .war file and that fixed the problem.

Presence data from web service

Hello,
i like to get presence data from the presenceconsumer web service. But everytime a call getUserPresence i get a PolicyException (POL0002): 'Privacy verification failed for address %1, request is refused'.
I use a web service proxy generated from the wsdl of the presenceconsumer web service. Authentication is made against the appregationproxy by setting username and password. Both users (the one i use for authentication and the one whose presence data i want to get) are registered in the timesten database.
The user whose presence data should be accessed is logged in the OracleCommunicator and has the other user on the allowed list for presence data.
All other operations of the presence web services work without any problem, so why not getUserPresence?
Thanks for help

Hi,
I have found the problem and fixed it :)
If you see my code, I was checking for the pending subscriptions after publish() method. When I tried this check before publish() method, I got the expected results (All the pending subscriptions).
Also, I got an error (ServiceException) while dynamically retrieving the subscribed attributes for some reason. I have found an alternative solution, by manually allowing only the PresenceAttributeType.Activity (instead of all getSubscribedAttributes()).
Note: This code was working fine in my local machine because, I have already setup-ed the users (Buddy list) through Oracle communicator in my machine. I was not able to install OC in the VM for some reason though OS is same in both my machine and the VM (OS: Windows 2000 SP4).
thanks & regards,
S.Vasanth Kumar.
My latest code for your reference.

How to connect a PDF form to SQL server database through web service?

Hi,
I'm new to LiveCycle designer. I have designed a PDF form in LC designer ES2, which suppose to take a personnel number and retrieve the personnel information from a SQL server database. Currently its working fine with XML data and a search button, but I need to securly connect to a database through web service. I know how to connect to a wsdl file through designer. What I need is a wsdl file to connect the form to database. For this purpose, is there any WSDL code to use as the web service?
I really appreciate your help and advice.

Create a schema from web service in eclipse

Hi all,
I'm trying to export some data out of SF to an 3rd party via a web service. In the webUI I have the possibility(Attachment 1) to create a schema from web service so my outgoing file matches the requirements. In Eclipse I cannot find that option and I'm encoutering some errors (attachement 2).
Can anyone tell me if there is a possibility like the web UI in eclipse?

Trying to access 10gr2 database from sqlplus utility but it connects to 11g

Hi All,
I am facing below issue while access 10gr2 database from sqlplus.
I am having two oracle homes on one server one belongs to 11gr2 and another belongs to 10gr2.
I want to access a 10gr2 database through sqlplus utility.but instaed of connecting to 10gr2 it is connecting to 11gr2 after I enter a user name and passowrd.
I have set all the env variables such as oracle_home ,oracle_sid and path with respect to Oracle 10gr2.
Can you please let me kno what I need to do to connect to 10gr2 database and not 11gr2 database through sql plus.
Let me know if I need to give any more details on this.
Best Regards,
Dipti S

Hi Rocky,
I got the resolution.
I made a mistake by creating an oracle instance/service(e.g. fsdmo) when Oracle_home was pointing to 11gR2 Directory.so that service was refering to 11gr2 oracle home.
hence when I was setting oracle_sid(fsdmo) and trying to access database instance from 11g sqlplus utility ,it was directing to 11g and not 10g since oracle service was pointing to 11g.
So now after chnaging the oracle home directory to 11g,I am creating a service and its working fine.
thank you so much for responding.
hope I am clear with my reply.
Best Regards,
Dipti S

OutofMemory Error while sending file to database using Web services

I have a file of 30MB to be written to the MySQL database. I am doing this in Axis web services and it gives me the following error:
(I am using Tomcat as the application server and Apache as the web server, Axis 1.3 and MySQL standard 5.0.21 version. I have set the minimum and maximum heap size and it works well without using the web service (just uploading and downloading from the database using a simple java program). Another thing to notice is that I can send a file of almost 10MB size to the database using web service without any problem. But it doesn't work with the 30 MB .)

Sorry for the delayed response here, forget to add it to my watchlist. I didn't catch if you were using Java 1.5 or not. Prior to 1.5 the default maximum heap space was 64MB which with the overhead of the appserver might be your problem.
Take a look at http://java.sun.com/j2se/1.5.0/docs/guide/vm/gc-ergonomics.html and the java -Xmx <size> command line option to change the default (I believe the size argument is in bytes, but don't hold me to that). I think you can pass that as a command line option to the startup script, but you should check the doco to see if it needs to be wrapped in some other arg etc.,
I seem to recall running into this same problem a few years back when I had a servlet doing some intense graphics processing on the fly and setting this option fixed the problem.

Hi expert,
Can I directly access BEX query from web version ? I know we can access bex query from webi rich client.
Many Thanks,

Hi,
Yes, you can access BEx query via BICS connection (OLAP Connection).

Sending Infopath content to a database or web service

Hi,
I have a sharepoint 2010 where I have 2 infopath forms used to enter data (each form has 5 por 6 fields). I need, once the data entered and validated, at the same time sent to a sql database or web service.
Can you please let me know the best route to follow. I read in this forum and on google that it can be done as importing to excel but I do not want any intermediary.
Thanks in advance

Hello,
In this video, i don't see any info about SQL OR ORACLE connector. It is simply about rest web service which can be used anywhere (with infopath, external list etc). As per my knowledge, by default there is no rest web service available in SP to connect
with ORACLE directly. Either you have to ask third party to provide you rest API OR you can create your own as i said earlier.
This thread will give you more idea:

Database Native web services - load balancing, Instrumentation , security

Hello –
I’m proposing use of Database Native web service in our company. Our architects are asking following questions so appreciate your help
a.     How do you load balance across the DB WS (is there a way to use the F5 to detect downtime and balance the load across the DB servers)? We will be using RAC configuration with 3 nodes.
b.     Our architect have security concern as user id/password information are in the web service URL, which may prove to be an issue. Is there a way to mitigate this risk?
c.     Instrumentation in this approach (db native services) is questionable due to development/auto gen of the service logic from the DB itself. We may investigate wrapping the services with OSB to give us an additional instrumentation, policy enforcement, endpoint mediation and security proxy. Thoughts??
d.     Architect are curious regarding any potential performance issues this may have on the DB server.
Thanks

Hi
We've recently begun using Native Web Services, intending to roll out this approach across the enterprise, but we've encountered 2 significant problems so far, which you may want to consider before proceeding ...
1. NWS returns an exception if the underlying PL/SQL returns a null value - even if the PL/SQL has completed successfully, and null is a legitimate return value (see SR 3-6201969101 - it contains simple instructions to recreate the problem)
(I raised it in this forum but there were no replies - SOAP Fault when returning null from a Native Web Service Stored Procedure
2. The sequence of values returned in the NWS response message is the opposite to the sequence declared in the auto-generated wsdl - i.e. schema validation will fail (see SR 3-6209016991 - it also contains simple instructions to replicate)
We have coded a workaround for problem 1. where we return <EMPTY> in place of null, and check for it in the client, but without proper resolution we're not prepared to use NWS elsewhere
As a workaround for problem 2. we removed schema validation, again not ideal
Both SRs were escalated 9 days ago, but are still outstanding
Incidentally our database is 11.2.0.1, but I've tested on 11.2.0.3 and both problems are still present
We also wrap the NWS services using an OSB Proxy Service, and came across the same security issue that you describe (b) - to provide the credentials required for the NWS, simply create a Service Account (containing the credentials) inside OSB and attach it to the Business Service which invokes the NWS (http://docs.oracle.com/cd/E17904_01/doc.1111/e15867/service_accounts.htm)

Facing problem while going to catch return result from web-services.

Hi everybody,
I am new to BPEL. I am facing problem while going to catch the attributes of resultsets returning from web-services(QAS). As far as my knowledge, two types of results it should return - XML entities and another is attributes which is coming as the part of XML entitites. I am able to catch the XML entities, but can't catch the attributes under it. Even, I am not able to see whether web-services returning something within that field.
When, I tried to catch the attribute and store to a temporary varilable using the following code:
*<assign name="AssignQASDoGetAddress1">*
*<copy>*
*<from variable="InvokeQAS_DoSearch_OutputVariable"*
part="body"
query="/ns6:QASearchResult/ns6:QAPicklist/ns6:PicklistEntry/@PostcodeRecoded"/>
*<to variable="temp"/>*
*</copy>*
*</assign>*
but, I am facing the following selectionFailure errors after running it:
*"{http://schemasxmlsoap.org/ws/2003/03/business-process/}selectionFailure" has been thrown.*
-<selectionFailure xmlns="http://schemasxmlsoap.org/ws/2003/03/business-process/">
-<part name="summary">
*<summary>*
empty variable/expression result.
xpath variable/expression expression "bpws:getVariableData('InvokeQAS_DoSearch_OutputVariable', 'body', '/ns6:QASearchResult/ns6:QAPicklist/ns6:PicklistEntry/@PostcodeRecoded')" is empty at line 269, when attempting reading/copying it.
Please make sure the variable/expression result "bpws:getVariableData('InvokeQAS_DoSearch_OutputVariable', 'body', '/ns6:QASearchResult/ns6:QAPicklist/ns6:PicklistEntry/@PostcodeRecoded')"is not empty.
*</summary>*
*</part>*
*</selectionFailure>*
Getting this error it seems to me that web-service is returning nothing, but, it returns something as it has been catched using a method called isPostcodeRecoded() Java Code in Oracle ADF. This method has been used as it should return boolean whereas for catching the xml entities using java code we used the method like getPostcode(), getMoniker().
For your information, we are using Jdeveloper as the development tool for building the BPEL process.
Am I doing any syntax error. Please consider it as urgent and provide me asolution.
Thanks in advance.
Chandrachur.

Thanks Dave and Marc, for your suggestions. Actually what I found is QAS web-service is returning nothing as attributes when the attributes are set to the default value. For example, following is the part of the wsdl of the result which QAS webservice returns.
<xs:element name="QASearchResult">
- <xs:complexType>
- <xs:sequence>
<xs:element name="QAPicklist" type="qas:QAPicklistType" minOccurs="0" />
<xs:element name="QAAddress" type="qas:QAAddressType" minOccurs="0" />
</xs:sequence>
<xs:attribute name="VerifyLevel" type="qas:VerifyLevelType" default="None" />
</xs:complexType>
</xs:element>
<xs:complexType name="QAPicklistType">
- <xs:sequence>
<xs:element name="FullPicklistMoniker" type="xs:string" />
<xs:element name="PicklistEntry" type="qas:PicklistEntryType" minOccurs="0" maxOccurs="unbounded" />
<xs:element name="Prompt" type="xs:string" />
<xs:element name="Total" type="xs:nonNegativeInteger" />
</xs:sequence>
<xs:attribute name="AutoFormatSafe" type="xs:boolean" default="false" />
<xs:attribute name="AutoFormatPastClose" type="xs:boolean" default="false" />
<xs:attribute name="AutoStepinSafe" type="xs:boolean" default="false" />
<xs:attribute name="AutoStepinPastClose" type="xs:boolean" default="false" />
<xs:attribute name="LargePotential" type="xs:boolean" default="false" />
<xs:attribute name="MaxMatches" type="xs:boolean" default="false" />
<xs:attribute name="MoreOtherMatches" type="xs:boolean" default="false" />
<xs:attribute name="OverThreshold" type="xs:boolean" default="false" />
<xs:attribute name="Timeout" type="xs:boolean" default="false" />
</xs:complexType>
<xs:complexType name="PicklistEntryType">
- <xs:sequence>
<xs:element name="Moniker" type="xs:string" />
<xs:element name="PartialAddress" type="xs:string" />
<xs:element name="Picklist" type="xs:string" />
<xs:element name="Postcode" type="xs:string" />
<xs:element name="Score" type="xs:nonNegativeInteger" />
</xs:sequence>
<xs:attribute name="FullAddress" type="xs:boolean" default="false" />
<xs:attribute name="Multiples" type="xs:boolean" default="false" />
<xs:attribute name="CanStep" type="xs:boolean" default="false" />
<xs:attribute name="AliasMatch" type="xs:boolean" default="false" />
<xs:attribute name="PostcodeRecoded" type="xs:boolean" default="false" />
<xs:attribute name="CrossBorderMatch" type="xs:boolean" default="false" />
<xs:attribute name="DummyPOBox" type="xs:boolean" default="false" />
<xs:attribute name="Name" type="xs:boolean" default="false" />
<xs:attribute name="Information" type="xs:boolean" default="false" />
<xs:attribute name="WarnInformation" type="xs:boolean" default="false" />
<xs:attribute name="IncompleteAddr" type="xs:boolean" default="false" />
<xs:attribute name="UnresolvableRange" type="xs:boolean" default="false" />
<xs:attribute name="PhantomPrimaryPoint" type="xs:boolean" default="false" />
</xs:complexType>
here the attributes like FullAddress, PostcodeRecodedare , etc. are not being return by the web-service when it is getting the default value false. But, if it gets true then , it is being displayed at the BPEL console.
Do you have any idea how can I catch the attributes and its value even when it gets the default value which is already set. Previously, it was returning(it was not being displayed at the console).
Thanks once again for your valuable suggestions...!!!

Dates coming from web service

Hi,
I'm currently trying to consume in VC a CAF Application Service exposed as a Web Service. I'm able to retrieve what I want but I have a problem with dates format.
The web service returns dates in the following format: YYYY-MM-DDTHH:NN:SS
When I test my data service in VC it works fine. When I run my iview, VC swap the month and the day and compute the new date...
It's not just a problem of formatting with DVAL and DSTR because the date is already computed.
Example:
Date returned from web service: 2007-09-21T00:00:01
Date returned from test data service in VC: 21.09.2007
Date returned at runtime: 09.09.2008
VC understand 21.09.2007 not like DD.MM.YYYY but like MM.DD.YYYY so 21.09.2007 becomes 09.09.2008
I also tried to check on the server Regional and Language option but it doesn't come from there.
Have you ever faced this problem?
Thx

Hi,
It is a Web Service generated by NWDS (to expose my CAF Application Service)and deployed on the server.
The url si like http://<hostname>:<port>/mywebservice/Config1?wsdl
The Web Service runs correctly.
When I call a method of my web service to retrieve a list of objects (CAF Entity Services) and their attributes, it returns attributes of type String and Dates of type 'java.util.GregorianCalendar'.
It seems that VC doesn't correctly understand this type of Date at runtime

Thomas

Extraction from web service without XI

Hello all!
I want to realize data extraction scheme without usage XI
DB2 Stored proc -> Web Service -> BW
Is realy?

Hello can you refine your question with more specification?
Yes, it can possible data extraction from web service, but what you are exactly looking for?

WHY can't I access my database from an applet???????????

The security code won't let my applet access its own database (from its own server)..
I'm using getDocumentBase()
to try and tell it that it is my own damn file..
I keep getting :
java.securityAccessControlException: access denied <java.util.PropertyPermission jdbc.drivers write>
...etc.
This applet crap is really starting to piss me off. I can see why they came out with JSP.
All I need to do is access my database, update it, etc. It kind of defeats the purpose of being able to do jdbc from applets if you can't even access the database on your own damn server.
If you all don't have a clue, I'm freakin switching to PHP--I'm tired of this crap-I was thinking Java was a damn good language until I hit applets.

The simple answer to your question is: Because of security concerns.
The somewhat longer answer is that directly accessing a database from an applet is generally not a good idea. A lot of security-critical code like DB username/password must be hidden in the applet which potentially can be downloaded (and disassembled) by anyone that hits your webpage. Maybe you do an intranet solution with trusted users but that is not what applets were originally designed for.
The clean way is to make your applet talk to a servlet that talks to your database.
If that is not the way you want to do it, make sure that all client policy files (yes, on the browser machine) contain the permissions that your applet needs.
