Data sources in Embedded OC4J Server Preferences

I tried to modify JNDI name in data sources of Current Workspace, however, the
value couldn't be saved and it was restored to the default one ("xxxCoreDS").
Is it a bug?
The JDev is studio edition version 10.1.3.0.4
Thanks

For each connection that is created with wizard for "Database connections" a data source is created. Names should not /cannot be changed. I recommend you to create a new DataSource. Changing user-defined datasources should work without problem. Hope this help.

BUG: JDev 10.1.3.0.4 Embedded OC4J Server Preferences

If we specify in the Embedded OC4J Server Preferences->startup a OC4J installation to use for running and debbuging, click ok, and then delete the choosen directory and try again to access the Embedded OC4J Server Preferences, an error occurs. Appears an dialog and we can not alter this anymore.

Hi,
not sure on the limitation of dbms_output.put, but 4000 characters happens to be the maximum size of a varchar2 column....
I normally use dbms_output.put_line for debugging PL/SQL.
You could also post in the database forum if you have no luck here.

If you have Web project, check if HTML Root Directory has got a Null value ?
Double-click on the project to bring up project properties
Select Input Paths
See the value for HTML Root Directory.
If it is Null or invalid, edit to make sure it is valid and Click ok.
If not, create a new/empty project and see if you can launch Embedded OC4J server preferences dialog for that project.

How to set up data source for JDeveloper's embedded OC4J Server?

Help needed. I Created a BMP EJB and tried to test
it with JDeveloper's( version 9.0.3) embedded
OC4J server. For JDBC, I created a data source
in data-source.xml lacated in JdeveloperHome\j2ee\home\config. However,
when I run the test client. I got the error
from JNDI lookup:
java.rmi.RemoteException: jdbc/entdatasource not found
Could anybody with similar experience help?
Thank you in advance.
-John Wang

Try making your changes in the data-source.xml located @ JDev_root\jdev\system9.0.3.1035\oc4j-config.
You can tell that this is the one to be modified by watching the log when you start the OC4J server. Look for the line that says C:\JDEV\JDK\bin\javaw.exe -ojvm -classpath . . .
the -config option will point to where the server.xml is used from, the same dir should be where you get your data-source.xml

JDBC datasoure that works for embedded OC4J server of JDeveloper 10.1.3.4

Hi all,
I have this in the Application Module as JDBC datasource: java:comp/env/jdbc/DBCON
That works fine if I deploy the application on Oracle application- or tomcat-server.
On the connections tab in JDeveloper I have made a database connection with the name DBCON.
But when I run the application from Jdeveloper with the embedded OC4J server I get this error:
Unable to lookup Data Source at context java:comp/env/jdbc/DBCON
What do I do wrong?
Thanks in advance.

Hi,
Edit the <application_name>-data-sources.xml file under the root directory of your application, and setup a managed data source and connection pool with the data source having the correct jndi name, eg. jdbc/DBCON
You can either do this manually (which I find easier), or use the tool within JDev
Tools - > Embedded OC4J Preferences -> Current Workspace -> Data Sources -> New

pstmt.setString(1, studid);
ResultSet rs;
rs = pstmt.executeQuery();
//mypidm = rs.getInt("SPRIDEN_PIDM");
This part of the code drops through i.e. rs.next() always gets a false result
while (rs.next()) //evaluates to false so mypidm is always zero.
mypidm = rs.getInt("SPRIDEN_PIDM");
I am thinking that these two things are related.
Any Thoughts.

The tables are not created by default. You can configure your persistence.xml to define how you want tables to be created. The persistence.xml properties are defined in the TopLink class, EntityManagerFactoryProvider (oracle.toplink.<essentials>.ejb.cmp3).
Set the property, "toplink.ddl-generation" to "drop-and-create-tables" if you want them recreated every time your redeploy. Note this will delete all previous data in the tables, so make sure you do not leave this setting on when you go into production.

Problem using JDBC (JNDI) DataSource and data-sources.xml w/ OC4J

I have a JClient application developed in JDev X. It works fine when using a JDBC URL for the connection (which then writes the connection into the BC4J.xcfg files, one for each application module). However, I would like the app to retrieve the data source from the server's data-sources.xml file. However, when, on the configurations tab of the application module I set the connection type to JDBC DataSource, and give it the JNDI name, it does not work, either with the embedded OC4J or the stand-alone OC4J. Any suggestions???
In the stand alone OC4J I verified that the data source exists (using java -jar admin.jar ormi://nemethzoltan3 admin welcome -application adatklinika -testDataSource -location jdbc/adatklinikaCoreDS) ... so the data source is defined in the data-sources.xml. Of course the error I get is JBO-30003.
If I just try to "test" the data source in Jdeveloper (using the context menu of the app module, and setting it to use the adatklinikaCoreDS) I get a JNDI error: unable to lookup data source and at level 3 a "javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial". I checked, the data source is defined under tools->embedded OC4J properties->data sources.
If I try to run the main form, simply nothing happens.
Please help!!!

Ok, figured out why running from jdeveloper wasn't working: the embedded OC4J server wasn't started (start it by running an html page from your project or something...and make sure you don't have a stand-alone oc4j running). AND more importantly it didn't have the library "embedded oc4j client" library included (project properties -> profiles -> development -> libraries)...which is needed for whatever reason.
Now to try and get it working with the stand-alone OC4J...

The 10.1.3 version of JDeveloper (and the embedded OC4J) requires JDK 5.0 to run.
You can however set your project to work with JDK 1.4 in the project properties.

SQL not showing in Embedded OC4J Server window

Previously, when we'd run a page through JDeveloper, the sql statements that were used to execute the query would appear in the Embedded OC4J Server window in JDeveloper. Now they no longer appear (along with a lot of other logging data that used to appear). Is there a configuration setting somewhere to make this info appear again?

There is no such setting for OC4J log. Are you sure that you are looking at the right tab because there are generally 3 tabs on the bottom most log window which are Messages, Compiler and Embedded OC4J Server.

Embeded OC4J server within JDeveloper does not pick latest JAR files.

Hi,
Currently OC4J seems to be using an older version of JAXB1.0. Hence I created a shared library in my standalone OC4J server and imported the shared library while deploying my applicatoin in the ClassLoader task.I am trying to replicate the same in
my embeded OC4J server within JDeveloper.
I followed as indicated in readme.txt file in the \j2ee\home\shared-lib\ folder.
1) I created a folder called "jaxb" within /j2ee/home/shared-lib/. I then created a folder with the name "2.0" indicating the version number of the API.
2) I then added the relevant jaxb JARS to the jaxb/2.0 folder.
3) In the server.xml file available under /j2ee/home/config/ , I added the following entries.
<shared-library name="jaxb" version="2.0">
          <code-source path="jaxb-api.jar"/>
          <code-source path="activation.jar"/>
          <code-source path="jaxb1-impl.jar"/>
          <code-source path="jaxb-impl.jar"/>
          <code-source path="jsr173_1.0_api.jar"/>
          <code-source path="jaxb-xjc.jar"/>
     </shared-library>
I am still facing the issue where my embedded OC4J server is picking up the jaxb version 1.0.
What are the steps that needs to be taken to ensure that the embeded OC4J
takes in the jaxb2.0 version.

How to use the HTTP Analyzer with the embedded OC4J server?

JDeveloper version: Studio Edition Version: 10.1.3.0.3.3412
I have a web application, which I run in the embedded OC4J server.
I tried to use the HTTP analyzer to inspect http requests and responses, but I could not make the analyzer work.
I tried to setup the HTTP analyzer by looking at the help entry, but I could not make it work.
If the HTTP analyzer works for you in the embedded OC4J server, please write the steps on how to setup the analyzer.
(Maybe I could not make the correct settings about port numbers?)
Thanks in advance,
Regards,
Turgay Zengin

I was able to use the HTTP Analyzer by changing the proxy setting directly in Internet Options. Check the browser/proxy settings set in JDeveloper preferences and copy them to the Connections tab of Internet Options. See if that works for you.

Data Source for MS SQL SERVER

Need Help on how to add a data source from MS SQL Server. Please give an example using PUB as the database and the server is N12345\SQLSERVER. Thanks.

Connecting to SQL 2000 server worked very easily. Make sure you start the SQL Server and the Sun Java Studio Creator IDE. In the Server Navigator pane, right click on the 'Data Sources' node and pick up the menu item' Add Source'. This brings up a dialogue box wherein you need to insert info regarding the hostname, password, database information etc. For a detailed screen shots of this you see my page at
http://www.mysorian.com/htek. The last item in the scrolling page is the one you should look for.

SQL ENTERPRISE: The edition of Reporting Services that you are using requires that you use local SQL Server relational databases for report data sources and the report server database

The error below makes absolutely no sense! I'm using Enterprise Core...yet I'm being told I can't use remote data sources:
w3wp!library!8!03/05/2015-19:08:48:: i INFO: Catalog SQL Server Edition = EnterpriseCore
w3wp!library!8!03/05/2015-19:08:48:: e ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.OperationNotSupportedException: , Microsoft.ReportingServices.Diagnostics.Utilities.OperationNotSupportedException: The feature: "The edition of Reporting
Services that you are using requires that you use local SQL Server relational databases for report data sources and the report server database." is not supported in this edition of Reporting Services.;
Really? This totally contradicts the documentation found here:
https://msdn.microsoft.com/en-us/library/ms157285(v=sql.110).aspx
That article says remote connections are completely supported.
ARGH! Why does this have to be so difficult to setup?!?

Hi jeffoliver1000,
According to your description, you are using Enterprise Core edition and you are prompted that you can’t use remote data sources.
In your scenario, we neither ignore your point nor be doubt with what you say. But actually we have met the case before that even though the SQL Server engine is Enterprise but the reporting services is still standard. So I would recommend you to find the
actual edition of reporting services you are using. You can find Reporting Services starting SKU in the Reporting Service logs ( default location: C:\Program Files\Microsoft SQL Server\<instance name>\Reporting Services\LogFiles). For more information,
please refer to the similar thread below:
https://social.technet.microsoft.com/Forums/en-US/f98c2f3e-1a30-4993-ab41-acbc5014f92e/data-driven-subscription-button-not-displayed?forum=sqlreportingservices
By the way, have you installed the other SQL Server edition before?
