When using JNDI datasource no SQL logging is done

That is correct. SQL logging is performed in our connection/statement
wrappers. So if you use your own, we do not have the opportunity to perform
logging, as we are not wrapping the connection or statement.

Error when using OC4J Datasource

Hi,
A customer is using a Servlet to run in an OC4j instance and is using EJB's for data DML.
To work around the possibility that XMLTypes are not supported we do an update in the DoPost.
public void ejbPostCreate(String mediumnummer, String inzender, String inhoud, PrlBerichttypeLocal prlBerichttypeLocal)
OracleConnection oconnection = null;
OraclePreparedStatement opstmt = null;
CLOB tempCLOB = null;
try
oconnection = (OracleConnection)getConnection();
String sql = "";
sql += "update prl_xml_berichten SET ";
sql += "INHOUD = XMLTYPE(?) where id = ?";
opstmt = (OraclePreparedStatement)oconnection.prepareCall(sql);
System.out.println(sql);
System.out.println("username : "+ oconnection.getMetaData().getUserName());
tempCLOB = CLOB.createTemporary(oconnection,true,CLOB.DURATION_SESSION);
Writer writer = tempCLOB.getCharacterOutputStream();
writer.write(inhoud);
writer.flush();
writer.close();
opstmt.setCLOB(1,tempCLOB);
opstmt.setLong(2,id.longValue());
boolean test = opstmt.execute();
tempCLOB.trim(0);
if (!test) System.out.println("Succes !!!!");
else System.out.println("Failure!!!");
// connection.commit();
catch (Exception exc)
System.out.println("Fout bij inhoud update ");
exc.printStackTrace();
finally
try
if (opstmt != null) opstmt.close();
if (oconnection != null) oconnection.close();
System.out.println("create dopost gedaan...");
catch (SQLException sqlex)
sqlex.getMessage();
System.out.println("Fout bij afsluiten dopost");
When they are using the getConnection from the Datasource:
private Connection getConnection() throws NamingException, SQLException
InitialContext context = new InitialContext();
DataSource dataSource = null;
// Look up data source object in directory service using JNDI
dataSource = (DataSource)context.lookup("jdbc/prlDS");
// Establishing db connection
return dataSource.getConnection();
The following error occurs:
username : PRL
create dopost gedaan...
com.evermind.server.rmi.OrionRemoteException: javax.ejb.EJBException: java.lang.AbstractMethodError: oracle.jdbc.OracleConnection oracle.jdbc.OracleConnection.unwrap()
java.rmi.RemoteException com.evermind.server.ejb.EJBUtils.getUserException(java.lang.Throwable, boolean) EJBUtils.java:263
java.lang.String CheckIn_StatelessSessionBeanWrapper8.checkInMessage(java.lang.String[]) CheckIn_StatelessSessionBeanWrapper8.java:126
When we change it to the connection setup with a hard string it does work:
private Connection getConnection() throws NamingException, SQLException
DriverManager.registerDriver(new OracleDriver());
return DriverManager.getConnection(Receiver.DATASOURCE);
Does anybody have an idea what the difference is with the direct connect string or the datasource from OC4J.
I attached the full error and the datasource.xml.
Regards,
Remco

Hi Remco,
You may not be aware of this, but the "Connection" returned from a "DataSource" is not necessarily the same as the one returned from "DriverManager". If I remember correctly, there was a similar question to yours posted to this forum, not so long ago. As I recall, Steve Button mentioned that there are emulated and non-emulated "Connection"s. I saw no mention in your post regarding which version of OC4J you are using, so I will assume the latest, stand-alone, production version (9.0.3). The Data Sources chapter of Oracle9iAS Containers for J2EE Services Guide has more details.
Good Luck,
Avi.

How to use jndi datasource on Weblogic instead of adding a DB data source

Hi All,
version: 11.1.1.4
I am trying to figure out how in my ADF applications I can use an existing jndi datasource out on our weblogic servers instead of having to bury the Database db source in my adf applications. Like SOA I would like to reference the DB directly during design so I can pull in entities and build view objects, but when I deploy I want it to reference the jndi datasource out on the weblogic server.
Is this possible? If so I am not sure how to configure it like I would a DB adapter in SOA.
As always appreciate the info.
Thanks,
S

If you use ADF in the model layer (application modules) you can configure them to use JNDI Datasources. Just right click on the application module and select 'Configurations...'. In the next dialog you see all the configurations currently available (one named xxxxxlocal and one named xxxxxshared at least). Select the local and hit the edit button. This open the DB connect dialog where you can change the connection from JDBC URL to JDBC Datasource (JNDI). Save your work and when you now start the app it will use the JNDI name.

Error when using Oracle Migration WorkBench (Sql Server 2k to Oracle 8i)

I'm trying to migrate a Sql Server 2k database to an Oracle 8i schema using OMWB. After using BCP to collect metadata information on the source database, I tried to capture the source data model and got a "Capture aborted" message on the progress screen (even though then it appears a dialog window reporting "0 errors and 0 warnings", funny!). Down there is the error log OMWB generated. After reading some posts, I changed some columns of the OMWB dictionary that holds the source database name, but still got the same error. If someone can enlighten me on this toppic, I'd greatly appreciated it.

How can I configure ang use JNDI datasource on Tomcat 4.0.x ?

How can I configure ang use JNDI datasource on Tomcat 4.0.x ?
Please help me , Thanks !

Hello ,
You need to go through the JNDI tutorial which you can access at the sun's site. It will explain all the things you need.
By the way all you want to use JNDI datasource is JNDI class library and some naming or directory service provider, which also you can download from sun.
Good Luck.

How to use JNDI datasource instead of database connection settings JDev 10g

Hi,
In order to use the different database from other environments, we are not able to use the JNDI datasource configuration settings, all the time need to configure the database connection settings from JDeveloper by changing the database connectivity settings in the JDeveloper for each environment separately, need a solution on how to make the database connectivity unique using the JNDI datasource name for all the environments for database connectivity settings through the application server console rather than changing the database adapter configuration in JDeveloper.
Please provide the update at the earliest. Your help is greatly appreciated. Thanks in advance..

What are you not clear on?
What you need to do is get your developers to conform to a database naming standard, as stated above, so if you have an oracle database that is for eBusiness Suite you get all developers to create a DB connection in JDev called, ora_esb as an example.
When the developer creates a DB adapter this will create a JNDI name of eis/DB/ora_ebs. When the BPEL project is deployed it looks for the JNDI name in the oc4j-ra.xml file to see its connection details. If they don't exist then they use the developers connection details. The issue with this is that they generally always point to the development DB. It is best practice for the developers to remove the mcf settings in the DB adapter WSDL. This way if the JNDI name has not been configured it will fail.
So when you migrate from dev-test-prod what you have is the JNDI name eis/DB/ora_ebs. The dev points to the dev instance of ebs, test points to the test instance and so on. This means that you don't need to adjust any code in the BPEL projects.

Hi Jeremy,
I've tried adding:
php_value upload_max_filesize 30M
to the .htaccess file but I get a 500 Internal Server Error
Seems like using .htaccess files has been deactivated by your host.
Please try with adding...
...on line 1 of the script which needs that, and see if that works -- if even this doesn´t work, I fear I can´t provide any other suggestion than transferring your site to a hosting provider which handles stuff the standard way and doesn´t force you to use such odd workarounds, which I have never heard of.
Sorry, needed to get that off my chest, but some hosting companies out there are really strange :-)
The problem is that I use the php.ini files to override the server setting
I suspect (can be wrong though) that the php.ini file placed in whatever directory will start "from scratch" everytime a document in that folder is "triggered", and that´s why the session of page A are getting destroyed on page B

I need to fix a virus when using firefox, which is this: Log in to X Marks

Recently several minutes after entering internet to see my mail, when using Firefox in my new Toshiba computer, a virus appears like a little box with the inscription "Log in to X Marks", impeaching me to continue checking my electronic mail. Today I have run Malwarebytes and Mcfee with any sucess at all. I thank you in advance for your help

Since many bad add-ons install outside of Firefox and don't have a remove button, here's my suggested procedure for tracking down and cleaning up bad add-ons. I know it seems long, but it's not that bad.
(1) Open the Windows '''Control Panel''', Uninstall a Program. After the list loads, click the "Installed on" column heading to group the infections, I mean, additions, by date. This can help in smoking out undisclosed bundle items that snuck in with some software you agreed to install. Take out as much trash as possible here.
(2) Open Firefox's '''Add-ons page''' using either:
* Ctrl+Shift+a
* "3-bar" menu button (or Tools menu) > Add-ons
* in the Windows "Run" dialog, type or paste <br><code>firefox.exe "about:addons"</code>
In the left column, click '''Plugins'''. Set nonessential and unrecognized plugins to "Never Activate".
In the left column, click '''Extensions'''. Then, if in doubt, disable (or Remove, if possible) unrecognized and unwanted extensions.
Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.
Any improvement?
(3) You can search for remaining issues with the '''scanning/cleaning tools''' listed in our support article: [[Troubleshoot Firefox issues caused by malware]]. These on-demand scanners are free and take considerable time to run. If they finish quickly and especially if they require payment, you may have a serious infection. I suggest the specialized forums listed in the article in that case.
Success?

Hi Carsten,
I tried to reproduce your problem, but couldn't. Let me explain what steps I executed and perhaps you can advise where I've not matched your steps.
--Using build jdeveloper 9.0.3.3.1203, I built a new bc4j project containing a dept-emp default bc4j project (deptEntity, empEntity, deptView, empView, deptempFKAssoc, deptempFKViewLink, ApplicationModule).
--In dos shell, I went to the directory \jdevdir\jdev\bin and ran setvars -go to set the correct jdk version
--In the dos shell, in the directory \jdevdir\j2ee\home I executed the following command to install oc4j:
java -jar oc4j.jar (defaults pswd to welcome for admin)
--I remoted the appmodule to EJB Session Bean (BMT) and created a new deployment profile using the 9ias configuration for the application module.
--I deployed the bc4j objects to oc4j
--I created a new project
--In this project I created a new jclient master-detail form using the above project's application module for the data model
--I saved all and compiled the jclient project
--I ran the jclient form and inserted a master record
--I committed the transaction successfully
--I browsed records, then edited a record
--I committed the transaction successfully, then browsed.
Is there something I've missed? Did you migrate your project and not start by creating a new project? Is there something special about the database schema you are using?
Thanks,
Amy

AuthenticationFailedException when using JNDI and JavaMail with SMTP auth

Hi all - I've been banging my head on this one for awhile now - hopefully someone else has done this.
We are working in a servlet container (tomcat), and need obtain a mail session from JNDI. We do this as follows:
               Context initCtx = new InitialContext();
               Context envCtx = (Context) initCtx.lookup("java:comp/env");
               Session mailSession=(Session) envCtx.lookup("mailSession/trumpetinc");so far so good. The jndi entry for the mail session is configured in server.xml as follows:
          <Resource name="mailSession/trumpetinc" scope="Shareable" type="javax.mail.Session"/>
          <ResourceParams name="mailSession/trumpetinc">
            <parameter>
              <name>mail.smtp.host</name>
              <value>mail.server.com</value>
            </parameter>
            <parameter>
              <name>mail.smtp.password</name>
              <value>ABCDEFG</value>
            </parameter>
            <parameter>
              <name>mail.smtp.user</name>
              <value>trumpet_kevin</value>
            </parameter>
         <parameter>
           <name>mail.smtp.auth</name>
           <value>true</value>
         </parameter>
          </ResourceParams>With the above, whenever we hit Transport.send(msg), we got an AuthenticationFailedException thrown. I have run into this before with SMTP authentication, so I decided to try using the transport.sendMessage() method instead.
So, I get the transport:
Transport trans = mailSession.getTransport("smtp");
trans.connect();Then I send my message using:
msg.saveChanges();
trans.sendMessage(msg, msg.getAllRecipients());and finally, I close the transport:
trans.close();Unfortunately, I'm still getting the exception. Is it possible that my connect() method is not picking up the JNDI properties set in the server.xml file (this seems likely)? If so, what's the best way for me to get those properties so I can set them explicitly in the connect() method?
Thanks in advance,
- Kevin

Hi,
I have faced the same problem and after some googling and trying I have discovered what causes the AuthenticationFailedException exception. I just wanted to share the knowedge maybe it will be helpfull to others.
Here it is what the API says:
To use SMTP authentication you'll need to set the mail.smtp.auth property (see below) and provide the SMTP Transport with a username and password when connecting to the SMTP server. You can do this using one of the following approaches:
1.Provide an Authenticator object when creating your mail Session and provide the username and password information during the Authenticator callback.
Note that the mail.smtp.user property can be set to provide a default username for the callback, but the password will still need to be supplied explicitly.
This approach allows you to use the static Transport send method to send messages.
2.Call the Transport connect method explicitly with username and password arguments.
This approach requires you to explicitly manage a Transport object and use the Transport sendMessage method to send the message. The transport.java demo program demonstrates how to manage a Transport object. The following is roughly equivalent to the static Transport send method, but supplies the needed username and password:
Using the Transport.connect makes the JNDI not very helpfull for configuration.
It seems that using just the mail.smtp.user and mail.smtp.pass is not sufficient for the authentication.
so, the solution is :
just place these to lines in the JNDI configuration:
          username="test"
          password="test1"
so it should looks as follows:
          <Resource name="mail/Session" auth="Container"
          type="javax.mail.Session"
          username="test"
          password="test1"
          mail.transport.protocol="smtp"
          mail.smtp.auth="true"
          mail.smtp.host="localhost"
          mail.smtp.port="25"
          mail.smtp.user="test"
          mail.smtp.password="test1"
/>
where test and test1 are the user's credentials

How to sort specific column when using GROUPING SETS in SQL Server?

If I remember correctly, in SQL Server, it is not recommended to use "ORDER BY" when there's already a GROUP BY GROUPING SETS.
I have two columns: [UPC#] & [Description] both are varchar.
My grouping sets is like this:
GROUP BY
GROUPING SETS
([UPC],[Description])
I don't have 'ORDER BY' but it's automatically sorting the Description column.
If I added a 3rd column, sum(Qty), then it doesn't sort by Description anymore. But if I added
ORDER BY [Description]
then the grand total of sum(Qty) will be at the first row instead of the last.
Is there a way to sort the Description column and still let the grand total of sum(Qty) be at the last row instead?
Thanks.

Yes, it works.
Thank you.
Could you kindly explain the logic?
I don't quite understand the "= 3 THEN 1 ELSE 0" part.
Is the #3 mean the column index 3?
GROUPING_ID returns a bit mask value depending on number of columns grouped in the result
So when you do GROUPING_ID(([UPC]),([Description]))
it has two columns UPC and Description so bit mask will be as follows
0 ie 00 for rows grouped by both UPC and Description fields
1 ie 01 for rows grouped by UPC ie UPC subtotals
2 ie 10 for rows grouped by Description ie Description subtotals
3 ie 11 for rows not grouped by both columns ie Grand total

VersioningError when Using JDBC driver for SQL Server with RMI

Hi,
I wrote a simple class for inserting rows into a database. The database is SQL Server 2000, and I am using weblogic's mssqlserver4 driver. The class works fine, but when I try to export the class as a remote object (using Sun's RMI implementation, not Weblogic RMI), I get the following error:
Exception in thread "main" weblogic.common.internal.VersioningError: No WebLogic packages defined in CLASSPATH at weblogic.common.internal.VersionInfo.<init>(VersionInfo.java:35) at weblogic.version.<clinit>(version.java:18)

Can anyone tell me why this happens? What is difference between using the driver standalone and using it with RMI? Does it have anything to do with the fact that I'm using Javasoft RMI and not Weblogic RMI? I'm pretty sure I have the classpaths set up correctly.
Thanks,

BoHi. Show me the whole stacktrace of the exception. The issue seems to be the driver licensing
code, which is looking for the bea.license file, and not finding it. Have your code run a System command
to find and print out the classpath it thinks is in effect. You will then see if the license file is there.

Data error when using Weblogic DataSource

I have set up a Datasource in Weblogic 10.3 using the JDBC Driver - Oracle's Driver (thin) Versions:9.0.1,9.2.0,10,11.
- provided with Weblogic Server.
When I execute a Servlet call - a certain line rs.getString () returns a wrong value.
For example we have a join Query that returns multiple records which have the same field returned in 5 records.
This feilds value is " 0000000" and it is of type "varchar" . Out of the 5 times rs.getString() is executed , 3 times it returns the following values: "0^H11508^H" "1501^H115" "0^H10000^H" .
Twice it returns the correct value.
This does not occur if the Servlet uses a direct Database connection and not the datasource pool.
So I think it is a Driver issue. What JDBC Driver should I be using when I create the pool.Also should I be setting Character Set or any other property,.
Our Database version is Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit Production.
Weblogic version 10.3 . Operating System - Linux Red Hat.
Appreciate your help. This is urgent since its in production now and users will start using this from Monday.

Hi. This indicates a bug in the driver, to do with
re-use of prepared statements (because the
statement cache will transparently dish up
the same statement for repeated prepareStatement()
calls.)
So, first upgrade the ojdbc14.jar in your server\lib directory
to the latest one you can download, and let us know if
the problem goes away or remains. Can we assume that you set
the statement parameters with exactly the same calls each time?

VS2010 Crystal Report Crashes System when using 'Set DataSource Location..'

Runtime ASP.NET 3.5
VS 2010
Under Database Fields (rt click) try Set DataSource Location... causes VS2010 to crash.
This is on an imported report from VS2008. VS2008 has no problem with the report.
Since this is a ASP.NET 3.5 program the internal property field
<ResGenToolArchitecture>Managed32Bit</ResGenToolArchitecture>
has been set in the project in order to allow the code to compile w/out errors.
What is solution for Crystal Report Set DataSource Location?

Hi Ken,
Here's one link on the issue: CRVS2010 RTM: Database Expert / External Component has thrown an exception
The reason is Old OS's used c:\temp as the default, now you are require to use %user%\temp as your temp folder as well as using the AppData folder for your app. If CR finds c:\temp it uses it and depending on what is in there it can cause Cr to crash, XML files have been know to do this.
Following MS's new rules on users temp folder should make your app Windows Compliant.
Thanks again
Don

DB Connections not being released when using Weblogic Datasource

I am using Kodo-JDO 2.5.3 and Weblogic 8.1.
I have JDO running as a JCA connector and I have a simple stateless session
bean persisting a simple object. My problem is that every time I call my
session bean to persist an object it grabs a connection from the Weblogic
connection pool and never returns it. So if I have configured a maximum of
50 connections in the pool, on my 51st call to the session bean I will get
an error saying it cannot acquire a connection from the pool. (error pasted
below)
I have configured my JDO parameters as follows:
ConnectionRetainMode=persistence-manager (also tried 'transaction')
TransactionMode=xa
ConnectionFactoryName=ERDataSource
ConnectionFactory2Name=NonXADataSource
At the end of every call to the SessionBean I perform a
persistenceManager.close(); and a persistenceManager=null;
Any ideas why connections are not getting re-used?
Exception I am receiving:
java.sql.SQLException: Internal error: Cannot obtain XAConnection
weblogic.common.resourcepool.ResourceLimitException: No resources currently
available in pool MyJDBC Connection Pool-1 to allocate to applications,
please increase the size of the pool and retry..

A couple of suggestions that might do the trick:
1. Upgrade to 2.5.4
2. Leave the ConnectionRetainMode to its default value (on-demand).
3. Make sure you always close your Query results and Extent iterators.

When using JNDI datasource no SQL logging is done
