Obtaining pooled connection in utility class.
Hello,
For our ADF application,
There is a utility class obtaining DB connection. Presently it is directly using JDBC to obtain the same. We need to change it to use connection from the Weblogic connection pool, that gets built at the start of server.
Please can you suggest a specific link that I can refer?
Regards,
Amar
Well create a datasource in weblogic and then in your AM - Configurations - Double click on Local - Application Module Tab - Connection Type section - Select JDBC DataSource - and in the datasource name give the name of datasource you created in weblogic

Obtain CallerPrincipal in a utility class
Hi,
I'd like to obtain the caller principal of a ejb from a utility class. I know I can easily get the EJBContext inside the ejb itself using the callback from the container to the setSeccionCoontect method, but what if I need to knwo the caller principal in a utility class called by a business method of my ejb?
By the way, I'm using EJB2.1 in Weblogic 8.1 and I'm talking about SessionBeans. I know I could obtain the caller principal inside my ejb and simply pass it as a parameter to my utility class, but I dont liek to idea of adding a user parameter to my utility clases method.
I'm aware that I could do a InitialContext.lookup("java:/comp/EJBContext") if I was using a EJB3 container, but I cant find the equivalent with EJB2.
Thanks!Every thread has a stack of its own and its own copies of local variables, if a static method uses only locals it doesn't have to be synchronized.
Using lazy initialization with the singleton pattern is a good example of side effects. Examine this code:class Singleton {
static Singleton instance;
static Singleton getInstance() {
if (instance == null) instance = new Singleton();
return instance;
// don't allow other classes to create an instance
private Singleton() {}
}Now what happens if two threads simultaneously enter the getInstance method and both find the value of the "instance" variable null in the if-condition? You end up creating an instance of the class twice, which is not what you want. This can be solved by writing the method declaration as "synchronized static Singleton getInstance()" so no two threads can enter the method simultaneously. -
Failed to obtain/create connection from connection pool after redeploy
I have a web application (.war) that uses a jdbc connection pool. The application works fine, however after I redeploy it using the administration console I get "Failed to obtain/create connection from connection pool [ Datavision_Pool ]. Reason : null" followed by "Error allocating connection : [Error in allocating a connection. Cause: null]" from javax.enterprise.resource.resourceadapter and I am forced to restart the instance. I am running Sun Java System Application Server 9.1 (build b58g-fcs)
using a connection pool to a Microsoft SQL 2000 database using inet software's JDBC drivers. I need to be able to redeploy applications without having to restart the instance. Any help is appreciated.I have turned on some additional diagnostics and found out some answers and a work-around, but I think that there may be a bug in the way JDBC connection pool classes are loaded. The actual error was a null pointer in the JDBC driver class in the perpareStatement method. The only line in this method is "return factory.createPreparedStatement( this , sql );" and the only possible NPE would be if the factory was null, which should be impossible because it is a static variable and it is initialized when the class is loaded. The problem occurs because we deploy the JDBC driver .jar file within our .war file, for use when a client doesn't have or want to use connection pooling. Apparently, the connection pool must have picked up some of these classes and when the .war was redeployed, the reference to the factory was lost for existing connections (not sure how). If I remove the JDBC .jar file from the .war, it works, but that wasn't an ideal solution, the other way to get it to work was to change the sun-web.xml file to have <class-loader delegate="true">. We previously had it set to false in version 8.1 because of interference with a different version of the apache Tiles classes, which has now been addressed in version 9.1.
I still think there is an issue, because the connection pool should never use the application specific classloaders. Am I wrong to believe this? -
Hi,
I am Shanmugavel, SharePoint developer,
I am facing the below SharePoint 2013 deployment issue while deploying using VS2012.
If i will deploy the same wsp or existing wsp
(last build) using direct powershell deployment, the solution adding properly, but the same timeout exception coming while activation the features. Please find the below error.
I tried the below activists:
1. Restarted my dev server, DB server.
2. tried the same solution id different server
3. tried existing wsp file (last build version)
4. Deactivated all the features, including project Active deployment configuration.... but still i am facing the same issue.
I hope this is not coding level issue, because still my code is not start running, before that some problem coming.
Please help me any one..... Last two days i am struck because of this...What you need to understand is the installation of a WSP does not do much. It just makes sure that you relevant solution files are deployed to the SharePoint farm.
Next comes the point when you activate the features. It is when the code which you have written to "Activate" certain features for your custom solution.
Regarding the error you are getting, it typically means that you have more connections (default is I guess 100) open for a SQL database then you are allowed to.
If you have a custom database and you are opening a connection, make sure you close it as well.
Look at the similar discussion here:
The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool
size was reached[^]
I would suggest further to look at the
ULS logs[^] to get better insight.

SecurityException: "Reserve" errors when obtaining jdbc connections
Hi,
We've seen an interesting issue come up with Weblogic 6.1 SP3. Not sure why this
is happening now.
I am using the MBean approach to creating Connection Pools dynamically. This still
works. The main thing I had to change for SP3 was to add a user/password when
I grab the Admin MBean. So this is all working fine.
The problem I get is when I try to make a connection. I end up getting a Pool
connect failed: java.lang.SecurityException: User "guest" does not have Per
mission "reserve" based on ACL "dynaPool". There were two ways I saw to solve
this, and I was wondering which was the best.
1) Add an acl that looks like "acl.reserve.dynaPool=everyone", and that seems
to work.
2) User the Driver.connect(String url, Properties aProps) where I include a "user"
and "password" key for the properties file. I use the same user/password that
I used to grab the Admin MBean. Problem is, I can't find any doc on this, or why
it works. Maybe you can enlighten me on why this works.
Anyway, I was curious on why 2) works, as well as which approach is the recommended.
We didn't see this reserve error until we tried to utilize SP3. Thanks in advance
for your assistance.
Michael DolbearHi Michael,
When there is no user provided, user "guest" is used.
AFAIR in SP2 in ACL was not defined on a pool, this effectively
allowed making connection to everyone, including guest.
I haven't worked on SP3, but it looks like the approach changed.
Speaking about the preferable way of making a connection,
the second one is better as the principal is clearly specified.
The first method can be harmful from security point of
view.
Hope it helps,

Hi Slava,
1) Getting the connection:
Properties tempProperties = new Properties();
tempProperties.setProperty(USER,
aUserName);
tempProperties.setProperty(PASSWORD,
aPassword);
tempDriver =(Driver)Class.forName(this.getJDBCDriverClassName()).newInstance();
tempConnection = tempDriver.connect(this.getJDBCDriverURL(),
aProperties);
2) My test case deletes the connection pool after its done, but
the main things to be know are
that I am using the weblogic.jdbc.jts.Driver and the url is
"jdbc:weblogic:jts:someName".
If that's not enough, I will get you the definition. The connection poolruns
on top of a two tier driver that is the Oracle thin driver.
3)Here is the stack trace. The is no weblogoic code in it (just ours), soI don't
think it will tell you much other than the message:

Data source for application using both pooled and non pooled connections
Hi guys.
I am integrating Oracle's connection pooling into an existing application that had formerly used dbConnectionBroker. It looks like this task should be quite straightforward. However, for consistency, I would also like to replace other Connection logic within the application to use Oracle classes. This will involve using OracleDataSource to obtain a Connection object. ( without pooling ).
So in this case, the application will use both pooled and non pooled Oracle connections. They will be connecting to the same database. The question I have is in regard to the use of data-sources.xml.
Are there any special considerations for the required attribute values within data-sources.xml under this scenario ?
Help will be greatly appreciated.
Regards.
Steve.Hi Steve -
It should be feasible for you to define a single datasource using multiple location entries to indicate what sort of pooling behaviour you wish to use.
If you lookup and use the "location" attribute, you will receive a javax.sql.DataSource object which will not provide connection pooling.
If you lookup and use the "ejb-location" attribute you will receive a DataSource object that will support connection pooling operations.
Note that this is using the emulated datasource approach, and transaction support is limited to a single resource (one database) for these datasources - you won't get 2PC support for transactions.
If you need a transaction to span two separate resources (ie two databases in same tx) then you will need to use the non-emulated datasource approach.
There is a chapter in the J2EE Services Guide which describes the datasource model we have with OC4J. This might provide you with some more useful information. See Chapter 11 - http://otn.oracle.com/docs/products/ias/doc_library/903doc_otn/generic.903/a97690/ds3.htm#1004903

NPE when using pooled connection
Hello. I have a client application connecting to an OC4J server running on a different machine. The OC4J server maintains a pool of connections to the Oracle database. My client is able to get the datasource from the server via jndi, and gets a non-null connection from the datasource. However, when I try to create a statement using the connection, I get a Null Pointer Exception. If I get a non-pooled connection from the datasource, everything works fine.
Here is the client code:
javax.naming.Context ic = getInitialContext();
javax.sql.DataSource dataSource = (javax.sql.DataSource)ic.lookup("jdbc/nanookDS"); //this gives you pooling
// javax.sql.DataSource dataSource = (javax.sql.DataSource)ic.lookup("jdbc/nanookCoreDS"); //this does not
for (int x=0; x<100; x++)
Connection conn = dataSource.getConnection();
if (conn == null)
System.out.println("null");
Statement stmt = conn.createStatement(); //fails here
ResultSet rs = stmt.executeQuery("select * from pmi.patient where patient# = 0");
rs.close();
stmt.close();
conn.close();
Can someone please tell me what's happening? I'm pulling my hair out...
BTW, the code above works fine when executed in a JSP on the OC4J server.
Thank you,

Design Advice Request - Using JDBC in a utility class
I have a utility class that I would like to use from any client code, regardless of whether that code is executing in a transaction or not.
This seems to greatly complicate the JDBC access from within the utility class. I appreciate any advice.
The utility class may both read from and write to the database. It currently attempts to detect whether it is in a transaction (it tests whether TransactionHelper.getTransactionHelper().getTransaction() is null to do this -- please point out if there is a better way.)
If in a transaction, the utility uses a data source which is linked to an XA connection pool, since it must assume other database activity may be occurring on the tx. If not in a transaction, however, it uses a data source linked to a non-XA connection pool, since the XA connection pool will not work outside of a transaction.
It seems like there should be an easier way -- are we overlooking some simpler solution?
The database is Oracle 9i and we are using the Oracle thin drivers.
Thanks in advance,

I am saying a non transactional DataSource, not a non XA data source. Ie, a datasource that
is unaware of whether there is a UserTransaction underway. A transactional data source can
be either XA or not. In the former case, multiple XA connections can and will be entrained
in any ongoing transactino, and non-XA (but transactional) datasources can and will be
used in a tx, but only one per tx because they have no 2-phase commit capability.
Ie; In the config file, you will see TxDataSource for a transactional datasource
to a pool (whether XA or not), and you will see DataSource for a non-transactional
data source.

Problem with EJB and JMS - Failed to obtain/create connection
hello ejb and jms programmers,
My problem is my topic MDB keep on retrieving the same message when there is a database connection failure. Maybe somebody could help me how to prevent to retrieve the same data?
Given:
- I purposedly turn off the pointbase database because im testing my error handling.
- Im using SJSAS 8 as my application server.
- My message Driven Bean of topic type.
- Im using CMP for my entity bean
Here is the scenario of whats happening - step by step:
1. A separate application publishes a message to JMS queue server
2. My MDB retrieves this message and do some processing then inserts a record (transaction history) in my database
3. But my db is turned off or down
4. My MDB sends a successful processing reply to the JMS queue server
5. Then i noticed that my server.log keeps on growing so when i opened it, the record was not inserted and printed the stacktrace below "RAR5117 : Failed to obtain/create connection. Reason : javax.transaction.SystemException" (complete stacktrace below)
6. I understand the cause of the stacktrace is because the DB is turned off. But what i dont understand is that my MDB keeps on reading the same message. Since my MDB is of topic type, isnt a topic MDB supposedly reads a message only once???
So my questions are:
1. how do i handle insert database error?
2. how can i stop my MDB from processing the same message?
3. any better suggestions?
Thank you in advance :)

Wherever you are handling database transactions,
you'd not be able to create a Connection if database
is closed (I think you mentioned turning off the
database) then at this condition, you should
certainly throw a System level exception and stop all
processing with some meaningful flow to indicate a
failure (like display message on UI). Even
network problems are handled by exceptions... so I
don't see a reason why you didn't wrap it in the
first place.
Anyway, try handling specific exceptions rather than
the general Exception... this will give you a better
idea of what to do in case of an exception.Yes i know this. I am practicing this in my non-j2ee server applications. But the j2ee app im making, i just pass the db url in the descriptor and the app server automatically creates the connection for my app. So where would i put exception handling?
2. how can i stop my MDB from processing the same
message?Guaranteed delivery is not supposed to stop
processing. It will continue to process the message
after certain intervals till the message is
delivered. You shouldn't deliver it at all, if you
are able to detect that the database is off
The problem here is that my MDB automatically retrieves the message from the JMS queue server. Im not the one retrieving the messages manually.
My assumed behavior of topic MDB is once the a certain MDB retrieves a message it will not retrieve the same message anymore.
thank you in advance.

Is there a Java utility class to help with data management in a desktop UI?
Is there a Java utility class to help with data management in a desktop UI?
I am writing a UI to configure a network device that will be connected to the serial port of the computer while it is being configured. There is no web server or database for my application. The UI has a large number of fields (50+) spread across 16 tabs. I will write the UI in Java FX. It should run inside the browser when launched, and issue commands to the network device through the serial port. A UI has several input fields spread across tabs and one single Submit button. If a field is edited, and the submit button clicked, it issues a command and sends the new datum to the device, retrieves current value and any errors. so if input field has bad data, it is indicated for example, the field has a red border.
Is there a standard design pattern or Java utility class to accomplish the frequently encountered, 'generic' parts of this scenario? lazy loading, submitting only what fields changed, displaying what fields have errors etc. (I dont want to reinvent the wheel if it is already there). Otherwise I can write such a class and share it back here if it is useful.
someone recommended JGoodies Bindings for Swing - will this work well and in FX?Many thanks for the reply.

Closing pooled connections?? one at a time?
I've got an interesting need;
I've writen a custom UserManager for form based authentication.
class ValidateLoginManager extends AbstractUserManager
Authentication is to a legacy DB (Oracle) where all users have
been added as
Oracle users. So I've created a separate JNDI data source in
data-sources.xml
for pooling connections that I'll only use for authentication
(just a gut decission).
The container calls:
boolean checkPasswd (username, passwd) {
boolean authenticated = false;
try {
dbConnection = this.datasource.getConnection(username,
passwd);
authenticated = true;
} finally {
if (dbConnection != null)
dbConnection.close();
return authenticated;
This works great, since Oracle authenticates the connection
against it's user DB.
But the conn.close() does not close the session on the DB and
soon all MTS tasks are used up in idle sessions.
Any thoughts on forcing the connection to drop open sessions?
thanks, curtHi Curt,
For my custom usermanager I use a datasource specified in my data-sources.xml like this:
<data-source
class="com.evermind.sql.DriverManagerDataSource"
name="xyz"
location="jdbc/OracleSecurityDS"
xa-location="jdbc/xa/OracleXADS"
ejb-location="jdbc/OracleDS"
connection-driver="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:@127.0.0.0:1521:xyz"
inactivity-timeout="30"
/>
When you lookup the datasource using JNDI, make sure you use the name bound to the location specified in the "location" attribute and not the "ejb-location" attribute (as you usually do in your Ejbs).
I hope this helps.

Please configure your SLD. Your SLD holds the system definition. Define a SAP WebAS abap system and then try to create a Metadata connection using WebDynpro content administrator. Now you will be able to see the msg server defined in the dropdown. Also ensure that you have the message server entry in your services file.
Refer these links for SLD

Could not create pool connection with MySql
When starting weblogic server I obtain the following error message when the conection
pool for a MySql database should be established. What's the mistake I am doing? #The
examples in the weblogic.properties put a "server=DEMO to the props. What is this
server related to the MySql RDBMS? Is it mandatory? After the error message produced
by Weblogic you'll find some information about the MySql setup (my.ini) I have made.

ClassNotFoundException on utility class in JTA Transaction
When using user defined transactions, I am finding I get odd
ClassNotFoundExceptions. I've tested this primarily on NT/2000, but did
also confirm it on Solaris. Can anyone explain it?
The exception only seems to occur if it becomes necessary to throw an
exception from the EJB. If I am not inside a user defined transaction,
there are no problems. (Even if the method is marked as Transacation
Required). Similarly, if no exception is thrown, there is also no problem
(even though I use plenty of other utility classes)
The classes (including the utility class) are all in my deployed jar file
(which is deployed as part of an ear file).
The error message is below:

Unable to Obtain a Connection to Hyperion Essbase from Planning Application
Dear All,
I have installed FDM+Foundation+HFM+Essbase+Planning 11.1.1.3 (Tomcat)
I have stacked with the following problem:
when I try to open my data form, I am getting
“Unable to obtain a connection to Hyperion Essbase. If this problem persists, please contact your administrator”
Validate Database Connection & Validate Essbase Connection are successful throw Manage Data Source menu
Essbase user has admin privileges
In EAS console I can make myself sure, that my application is running
Data Form is valid (verified in Preview screen in Data Form wizard)
Can somebody help me with it?
Best Regards,
SiarheiThanks, John
Summary
Symptoms
When attempting to connect to Hyperion Planning as the admin user, the following error occurs:
Unable to obtain a connection to Hyperion Essbase. If the problem persists, please contact your administrator'
Cause
Hyperion Planning web accesses the application by making a connection to the Planning metadata in the relational repository (via Relational repository settings) and also to Essbase via the datasource settings.
Any Essbase connection issues indicate problems with the Essbase settings in the datasource or are related to the Essbase server.
Solution
- Edit the datasource via the Configuration Utility.
- Test the Essbase connection and make sure that the user used to make the connection is valid and has admin rights to Essbase.
- Restart the Hyperion Planning service once the Essbase user has been given the correct access rights.
- Login to the Essbase Administration Services (EAS) console and right click on the Essbase server name node -> Refresh security from Shared Services
- Expand the applications node (under the Essbase server name node) and check that there is an application with exactly the same name as the Planning application.
Note: Go to section 'manually recreating a Planning application in Hyperion Essbase, if the Planning application is missing in the above step.
- Login to the application in Hyperion Planning web.
Manually recreating a Planning application in Essbase:
- Login to the EAS console as admin (the Essbase user used by admin must have Essbase administrator rights)
- Go to Essbase servers -> your Essbase server name -> right click on applications -> Create application -> Using Block Storage and enter the exact Hyperion Planning Application name then click on ok.
Note: The above step will only create the application shell without the databases.
- Login to the application in Hyperion Planning web as admin and go to Administration menu -> Manage Database -> select database and filters (to create filter access to Essbase) and Refresh (refresh will also recreate the databases if they don't exist)
Best Regards,
Siarhei
