Connection Failure for JDBC system in Session Bean using JCA

Hi,
I am trying to write a session bean that runs a query
against a JDBC system, but I keep seeing the following
error in the default trace file in the J2EE log folder:
14##0#0#Path##Java###Throwing
#1#java.sql.SQLException: Invalid connection string
attribute: Database name is required but not supplied#
#1.5#
This is the code, with the line marked (*) being the point where the exception is thrown:
public void getConnection(String sURL, String sUser, String sPassword) {
ManagedConnectionFactory mcf = null;
IConnectionFactory cf = null;
IConnectionSpec cs = null;
try {
mcf = new JDBCManagedConnectionFactory();
cf = (IConnectionFactory) mcf.createConnectionFactory();
cs = cf.getConnectionSpec();
cs.setPropertyValue("UserName", "sa");
cs.setPropertyValue("Password", "admin");
cs.setPropertyValue"driver",
"com.sap.portals.jdbc.sqlserver.SQLServerDriver");
cs.setPropertyValue("url",
"jdbc:sap:sqlserver://localhost:1433;DatabaseName=pubs");
conn = cf.getConnectionEx(cs); (*)
I have tried adding another property value, like so:
cs.setPropertyValue( "DatabaseName", "pubs");
(or) cs.setPropertyValue( "Database", "pubs" );
but I still get the same exception. What does this
exception really mean, what is missing from the
configuration information ?
Also, in the default trace file of the J2EE engine, the
configuration information is printed out, but in an
encrypted format, (see below), is it possible to have it
print out this information in a readable format ?

Hi Vladimir,
thanks for your response. The reason I am accessing a
JDBC source via JCA is to get a feel for how JCA works.
What I ultimately want to do is construct a bean that can
give queries to different kinds of sources; JDBC, and SAP
(R3, CRM), and possibly sources like Siebel. For this, I
believe I should use the Connector Gateway Service, as
described in the "Using the JDBC Connector" and "Using
the SAP Backend System Connector" sections of the SAP
Portal Developer's Guide. But for now, my first approach
was to use the approach described in "Connecting via
J2EE" subsection of "Using the JDBC Connector" (see
http://help.sap.com/saphelp_nw04/helpdata/en/30/a0f17aacb34b108b39a96acc33da3f/content.htm)
Thanks,
Colm.

Multiple inheritance in remote interfaces for EJB 3.0 session beans on Webl

Hi All,
We started migration from EJB 2.1(WLS 8.1) to EJB 3.0(WLS 10.3.2) and identified few serious problems. One of them is related with multiple business interfaces inheritance. I wrote simple example that presents point of the problem.
we have session bean AImpl:
+@Stateless(name="A")+
+@Remote({A.class})+
+@TransactionAttribute(TransactionAttributeType.REQUIRED)+
+public class AImpl implements A {+
+@Override+
+public void writeA() {+
System.out.println("A");
+}+
+@Override+
+public void writeB() {+
System.out.println("B");
+}+
+@Override+
+public void writeC() {+
System.out.println("C");
+}+
+}+
with remote interface A:
+@Remote+
+@JNDIName(A.JNDI_NAME)+
+public interface A extends B, C {+
public static String JNDI_NAME = "A_JNDI_NAME";
void writeA();
+}+
As you can see A extends B, and C. Definition of both interfaces is very simple:
+public interface B {+
void writeB();
+}+
+public interface C {+
void writeC();
+}+
Everything looks nice until we want to invoke some method on AImpl bean. For above implementation code:
A a = ctx.lookup(A. JNDI_NAME);
a.writeA();
a.writeB();
a.writeC();
writes down ”A \n B” and throws exception:
caused by: java.lang.NoSuchMethodException: pl.gov.arimr.zszik.bazowe.slowniki.ejb.A_vt0zts_AImpl_1032_WLStub.*writeC()*
at java.lang.Class.getMethod(Class.java:1605)
at weblogic.ejb.container.internal.RemoteBusinessIntfProxy.getTargetMethod(RemoteBusinessIntfProxy.java:165)
at weblogic.ejb.container.internal.RemoteBusinessIntfProxy.invoke(RemoteBusinessIntfProxy.java:57)
so.. in stub generated by WLS there is no method from interface C ! What more interesting after small change in interface A rely on change in interface implementation order from B, C to C, B (+public interface A extends C, B {+) server writes down only A and I have stack like below:
Caused by: java.lang.NoSuchMethodException: pl.gov.arimr.zszik.bazowe.slowniki.ejb.A_vt0zts_AImpl_1032_WLStub.*writeB()*
at java.lang.Class.getMethod(Class.java:1605)
at weblogic.ejb.container.internal.RemoteBusinessIntfProxy.getTargetMethod(RemoteBusinessIntfProxy.java:165)
at weblogic.ejb.container.internal.RemoteBusinessIntfProxy.invoke(RemoteBusinessIntfProxy.java:57)
After this experience I came up with suspicion that Weblogic 10.3 does not support inheritance from multiple interfaces in one “generation”. Instead of that it takes only the first interface from the list.
Does anybody have some experience with such a situation? maybe someone have an idea how to work around this problem?

This is Not Supported in WebLogic that the Remote Interface extends other Interfaces. Because Annotation Processor just looks up inside the implemented interface methods. The actual interface which is Implemented by the Bean Class. So the Methods declared inside the Interface B and Interface C will be ignored and will not be available as part of the generated Stubs. Thats why u are getting NoSuchMethodError.
You can even contact Oracle Support on this...there are 3-4 Cases on it. And the Solution is Work As Designed.
Workaround is : edit your interface A as following
Declare all the Business Methods only in the Remote Interface and not inside it's Super Interfaces.
Example:
@Stateless(name="A")
@Remote({A.class})
@TransactionAttribute(TransactionAttributeType.REQUIRED)
public class AImpl implements A {
@Override
public void writeA() {
System.out.println("A");
@Override
public void writeB() {
System.out.println("B");
@Override
public void writeC() {
System.out.println("C");
@Remote
@JNDIName(A.JNDI_NAME)
public interface A extends B, C {
public static String JNDI_NAME = "A_JNDI_NAME";
void writeA();
void writeB();
void writeC();

Portal Test Connection Failed for JDBC Connector

Hi,
We are trying to create a JDBC system in EP to connect SQL Server 2005 database. Our aim is to build a model in VC using data services from SQL Server 2005.
We deployed the Driver file sqljdbc.jar and connection was successful when tested by creating a data source in Visual Administrator-> JDBC Connector
We have created a system in EP with user mapping type (admin,user) and user mapping also done for system alias with the SQL Server administrator user id and password. UME is maintained in ABAP Stack. When we try for test connection with the system created in EP for JDBC connection, the system throws an error message like Connection failed. Make sure user mapping is set correctly and all connection properties are correct
Test Details:
The test consists of the following steps:
1. Retrieve the default alias of the system
2. Check the connection to the back end application using the connector defined in this system object
Results
Retrieval of default alias successful
Connection failed. Make sure user mapping is set correctly and all connection properties are correct.
The following are the URL and driver class name:
URL: jdbc:sqlserver://<host_name>:1433;DatabaseName=db_ name
Driver class name: com.microsoft.sqlserver.jdbc.SQLServerDriver
Is there any other setting to be maintained in the Visual Administrator or in the Portal?
Kindly let us know any clue to overcome this issue.
Quick response highly appreciated.
Regards
Saravanan.r

Hi Saravanan and Sathish,
not sure how far you got with this. I had the same problem or at least a very similar one with access to MS SQL Server 2005 and solved it. I followed essentially very similar steps with a couple of minor twists:
1) copied the sqljdbc.jar file to the storyboard server and set the classpath environment variable to point to it.
2) I did not create a data source, just created a new driver "SQLServer".
3) Under Connector Container I cloned SDK_JDBC as "SDK_SSQL".
4) The Visual Composer property vc.bi.sqlEditor Enabled should be set to true for you to be able the SQL Editor in the Data Service in VC.
In the portal I created a system of type BI_JDBC from a template.
The connection url and driver class were as in the thread:
URL: jdbc:sqlserver:ipaddress:1433;DatabaseName=name
Driver: com.microsoft.sqlserver.jdbc.SQLServerDriver
ConnectionFActoryClass as above under 3.
User rights: admin,user
The user mapping to the system alias should be as described.
This should allow you to use the data service in VC to access SQL Server tables. If access to stored procedures (sometimes quite useful) is required, this would need to utilise the p9sqlserver.jar file already on the server.
Best Regards
Felix Logemann

JDBC System Connection VS BI JDBC System Connection

Hi All,
I've created a BI JDBC System which connects to the MS SQL Server 2005, and the connection tested successfully. I am now able to browse for tables.
But I need to access stored procedure as well, so i created a JDBC System with the same Database URL, Driver Class Name, and User Mapping. But i failed the connection test with the error:
com.sap.guimachine.portalconnector.commandhandler.CommandException: Failed to connect to backend system. Check your system definition and user privileges.#
Any idea?
Thanks & Regards,
Sarah

Hi!
See http://wiki.sdn.sap.com/wiki/display/VC/Step-by-Step%2bguide%2bMaxDB%2bJDBC.
and notes - 773401
attention to: change_ref -m com.sapportals.connectors.database library:MAXDB_DRIVER
and: user mapping to database user with necessary authorities
very usefull testing connection through VA-JDBC Connector- create datasource (fill url + user/psw) and "db initialization" - select * from la-la

A tough one for EJB experts - Stateless session bean spec question

I am busy learning more about EJBs and came across something confusing regarding the legal operations in the various container callback methods for stateless session beans.
Specifically, the EJB spec states that in the ejbCreate() method, the SessionContext can be used to obtain a reference to the EJB Object. Now this makes perfect sense with stateful session beans, since the ejbCreate() method isn't called until a client is creating a bean and the container has linked that bean to the client's EJB Object. However, it is my understanding that when it comes to stateless session beans, the container creates the beans and adds them to the bean pool at its leisure. It is not until a business method is called by a client that a stateless bean is actually linked to an EJB object. So, how is it that a stateless bean could ever obtain a reference to an EJB Object from within ejbCreate(). Which EJB Object would it be linked to? This operation just doesn't appear to make sense in that context.
Can anyone clarify this for me?

Interesting question. I have such questions all the time! Here's a link to a similar discussion
http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic&f=70&t=000905
Also, I tried this using Weblogic 8.1. Tried to access the EJBObject in ejbCreate before any business method was invoked. I did this by specifying a value for initial-beans-in-free-pool and found that the hash code for the EJBObject was the same for all the bean instances that were created on startup.
I then invoked a business method and accessed the EJBObject in that method. Again the hash code for the object was the same as the one created on startup.
Seemed to be that there is a 1:n relation between the EJBObject and bean instances.
This may be container specific. The spec says the user should be able to invoke the getEJBObject() method in ejbCreate(), its upto the container to comply with it.

Could not access Local Session Bean using JNDI lookup

Hi EJB Guru,
I am quite new to EJB 3.0 but have had a good deal of success including using JNDI to lookup Remote Stateless Session Bean in EJB 3.0. However, looking up local Stateless Session Bean prove more challenging with I had anticipated.

Hi Henry,
Any direct global JNDI lookup is not portable. It works in some cases but not in others, which
is why we recommend using the portable Java EE approach of declaring an ejb dependency
and looking up that dependency via the bean's component environment (java:comp/env).
This is true whether you're dealing with Remote or Local ejb dependencies.
Local ejbs are not supported in the Application Client tier at all. In the server tier, there is no
guarantee that a Local EJB even is assigned a global JNDI name since there's no requirement
that it be available outside of the application in which the ejb is defined.
You can find more information on these ejb access topics in our EJB FAQ :

Making AQ usage transactional across session beans, using mosly JMS syntax

I need to determine what I need to have in place in order for JMS/AQ messages to be "fully transactional".
I have a J2EE server application that will send JMS/AQ messages to a queue. I have a standalone application that reads messages from the queue, does some work, and then makes calls on multiple session beans (hosted in the original J2EE server application). Actually, it would likely be multiple calls to the same session bean method.
Once the standalone application reads a message from the queue, I need to ensure that if any action performed as a result of that message fails, that all the operations performed, including the removal of the message from the queue, are rolled back.
First of all, if I use an Oracle XA-compliant datasource, if one of the session bean calls fail, I can rollback the current transaction, but will this properly roll back any work that earlier session bean calls (made on the same transaction) did, even if they were successful (at the time)? Note that I have two JVMs, one running the J2EE application, and the other a standalone application reading from the queue.
Second, on committing or rolling back the message retrieval itself, I noticed from examples in the Oracle AQ Application Developer's Guide that if I create my QueueSessions with "AQDriverManager.createAQSession()", that I can pass a Connection object, and then later "commit" or "rollback", manually, perhaps if I got an EJBException from a session bean call.
However, I am trying to write my JMS/AQ code so that it uses as little of the direct AQ api as possible, staying with the standard JMS api. As a result, I'm using the JMS version of this, which is "QueueConnection.createQueueSession()". When I do this, however, it seems as if I lose control over the transaction.

Ok, I think I've answered some of this for myself, but I still have some concerns.
I see that the QueueSession object that I get back from "queueConnection.createQueueSession()" is likely going to actually be an instance of the "AQjmsSession" class, so I can cast to that, and then I can call "commit" or "rollback".
What is unclear from the javadoc description is what happens when "close()" is called on the session object. Does this do an implicit "commit()", perhaps unless "rollback()" has already been called?
I'm still a little uncertain about whether the scope of my transaction will be wide enough to protect everything that needs to be protected.
For instance, I assume that my transaction starts when my consumer (not in an application server) reads the message from the queue. At that point, my consumer does some "screen-scraping" work. When it's done, it will call a session bean on the application in the application server (separate JVM, in other words), which will create some EJB entity objects and also insert raw database rows. The session bean will then return, and then the original method which read a message from the queue will be completed.
What I need to know is what will happen if ANYTHING in that process fails, either in the external consumer, or in the session bean, or creating EJB entities? That is, will the entire transaction be rolled back, undoing the EJB entity creations AND the removal of the message from the message queue?
If this can possibly work, I'm assuming this would be utilizing an XA datasource, or a non-emulated data source (which I think means the same thing).

My suggestion is to put some System.out.println() statements and see if the output helps in any way in debugging. I can't think of anything on the top of my head although I have been working lightly on SunONE.
By the way, you referred the stateless bean as CMP. Just wanted to tell you that you are wrong. The terms CMP and BMP refer to persistence, which is applied to Database tables and not to stateless/stateful session beans which are written for some specific purpose independent of underlying database.

Create session bean using interfaces, not implementation classes

Hi,
I'm using interfaces and session beans for my persistence/data layer in my adf application.
I've created a data control for my session bean and during creation of this data control, javabean.xml files are created for the different interfaces that are used in my session bean.
If I create bindings on these methods, interfaces in jspx-documents I will get errors because he can't find the impl-classes that implement these interfaces.
When using interfaces in your session bean (as return values or parameters) instead of classes you need to manually create javabean.xml files for the implementation classes.
It's required by the databindings/datacontrol that the implementation-classes are described in a javabean-format as well? Is this a spec we need to adhere to?
Could someone verify that you need to create javabean.xml-files for as well the interfaces as the classes when you're working with interfaces in your session beans?
regards,
Nathalie

A patch was released by Oracle to be able to work with Interfaces and so it's not required to work with implementation-classes.
Patch for 5726754(Base bug 5657179)

How to run a client program in Session bean using weblogic 8.1

Hi
I am new to weblogic server 8.1. I sucessfully deployed session ejb Session Bean. I created sessionbean jar file and put it it classpath also.
and also i created sessiobeanclient jar file, it included in class path.
While running client program it throws exception like noclass def found exception
plz tell me the right way to run the session ejb program.
bye

Hi,
You have to follow the given steps before you are going to run the client program that invokes the session bean .
1)set the Weblogic Environment using the tool setWLSEnv
2)place the Session bean jar file in classpath
3)run the client program
Note:If the client has to execute on remote machine we need to copy client class,remote interface, home interface and other classes which are used as
parameters and return types.

Test Connection fails for VC system of type Web Service

Hi All
I ve created a VC system of the type Web Service in Portal. In this VC system, I have given Url of the Enterprise Service that I want to use in VC.
(for eg: http://erp.esworkplace.sap.com/sap/bc/srt/wsdl/sdef_ECC_SALESORDER002QR/wsdl11/ws_policy/document?sap-client=800)
In the next step, I did user mapping for the VC user that will be consuming this Enterprise Service.
The system was created successfully but when I did Connection Tests , I got the following exception:
Test Details:
The test consists of the following steps:
1. Retrieve the default alias of the system
2. Check the connection to the backend application using the connector defined in this system object
Results
Retrieval of default alias successful
Connection failed. Make sure that Single Sign-On is configured correctly
Do I need to do any more configurations before I can use such ES portal system in my VC work studio ?
I understand that I have provided little information about the exception thrown by Portal.
I kindly request you to feel free in asking any other details about the same.
Regards
Kapil S Kamble

Hi Natty
thanks for your immediate reply.
I followed your instructions and created iView of the type URL and set the fetch mode property to 'server side' as told.
Initially, I gave 'http://www.sap.com' as the Url and I was successful in opening the site.
Later, when I gave Enterprise Service url and tried to preview the iView, I got the following exception:
*'http://erp.esworkplace.sap.com/sap/bc/srt/wsdl/sdef_ECC_SALESORDER002QR/wsdl11/ws_policy/document?sap-client=800
Error # 401'*
I ll need to give username and password. But how do i give them as parameters?
Please note, these parameteres are appended to the Url. So, I fear that if url of Enterprise service is changed, then it wont open.
what do you think ?

http://gimp-print.sourceforge.net/MacOSX.php3
The driver works fine with the Kodak P500 over USB.
However, neither Bluetooth Setup Assistant nor Printer Setup Utility will allow you to use it for Bluetooth printing. Bluetooth Setup Assistant recognizes the Kodak P500, but fails saying it can't find a driver. Apple did not provide a way to manually select a driver.
Likewise, Printer Setup Utility sees the printer (grayed out) when More Printers>Bluetooth is selected, but won't let you select it.
I have had similar problems setting up other printers in OS X. I do not understand why there is not always a manual option. On a few occasions I have been able to trick OS X by setting up another printer which uses the same path (USB, IP, etc.) then later changing the printer type (i.e. the driver) with Printer Setup Utilities Get Info window.
So maybe if you can find another Bluetooth printer which OS X will let you set up you can use that to give you an entry in Printer Setup Utility to edit to the Kodak printer. Given Bluetooth's security protocols this probably will not work as it would with a network printer.
Good luck.

The connection string for coded UI Data driven test using excel data source is not working

Hello,
I am using the visual studio 2012 coded UI test, i added the following connection strings to connect to an excel data source:
[DataSource("System.Data.Odbc", "Dsn=Excel Files;Driver={Microsoft Excel Driver (*.xls)};dbq=C:\\Users\\shaza.said.ITWORX\\Desktop\\Automation\\On-track Automation Framework\\On-track_Automation\\Automation data file.xls;defaultdir=.;driverid=790;maxbuffersize=2048;pagetimeout=5;readonly=true",
"Sheet1$", DataAccessMethod.Sequential), TestMethod]
[DataSource("System.Data.Odbc", "Dsn=Excel Files;dbq=|DataDirectory|\\Automation data file.xls;defaultdir=C:\\Users\\shaza.said.ITWORX\\Desktop\\Automation\\On-track Automation Framework\\On-track_Automation\\Automation data file.xls;driverid=1046;maxbuffersize=2048;pagetimeout=5",
"Sheet1$", DataAccessMethod.Sequential), TestMethod]
But i get the following error:
"The unit test adapter failed to connect to the data source or to read the data. For more information on troubleshooting this error, see "Troubleshooting Data-Driven Unit Tests" (http://go.microsoft.com/fwlink/?LinkId=62412) in the MSDN Library.
Error details: ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified"
Thanks,
Shaza

Thanks for Adrian's help.
Hi shaza,
From the error message, I suggest you can refer the Adrian's suggestion to check the date source connection string correctly.
In addition, you can refer the following about how to Create a Data-Driven Coded UI Test to check your issue:
http://msdn.microsoft.com/en-us/library/ee624082.aspx
Or you can also try to use a Configuration File to Define a Data Source for coded UI test.
For example:
<?xml
version="1.0"
encoding="utf-8"
?>
<configuration>
<configSections>
<section
name="microsoft.visualstudio.testtools"
type="Microsoft.VisualStudio.TestTools.UnitTesting.TestConfigurationSection,
Microsoft.VisualStudio.QualityTools.UnitTestFramework, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
</configSections>
<connectionStrings>
<add
name="ExcelConn"
connectionString="Dsn=Excel Files;dbq=E:\Unit Test\AddClass\AddUnitTest\add.xlsx;defaultdir=.;
driverid=790; maxbuffersize=2048; pagetimeout=60;"
providerName="System.Data.Odbc"/>
<add
name="ExcelConn1"
connectionString="Dsn=Excel Files;dbq=E:\Unit Test\AddClass\AddUnitTest\sum.xlsx;defaultdir=.;
driverid=790;maxbuffersize=2048;pagetimeout=60"
providerName="System.Data.Odbc"/>
</connectionStrings>
<microsoft.visualstudio.testtools>
<dataSources>
<add
name="ExcelDS_Addition"
connectionString="ExcelConn"
dataTableName="Addition$"
dataAccessMethod="Sequential"/>
<add
name="ExcelDS_Multiply"
connectionString="ExcelConn1"
dataTableName="Multiply$"
dataAccessMethod="Sequential"/>
</dataSources>
</microsoft.visualstudio.testtools>
</configuration>

How do you connect lines for a drawing in order to use the live paint bucket tool?

Hello! Im fairly new (okay not really) to using adobe illustrator
I used the Image trace tool to outline this drawing of Captain America but unfortunately the lines arent connected and therefore
messes up my colouring completely when I use the Live Paint Bucket tool.
Is there a way to connect the lines so they are closed when I colour it? Or is there another way to color this drawing?
Help would be greatly appreciated!

Those gaps are very wide. Draw some paths and apply no fill, no stroke to them.
Then make the live paint. In case the live paint already exists, you can go into isolation mode and then draw the paths. Or draw them and use Object > Live paint > Merge
