How to use JNDI look up from a JSP
Hello,
I know I should not be doing this (writing the lookup code in a JSP) but have to do it for some reasons.
I am using this code in my JSP:
try
Context ctx = new InitialContext();
dataSource = (DataSource)ctx.lookup("jdbc/mybillingora");
conn = dataSource.getConnection();
statement = conn.createStatement();
catch(Exception excep)
Is this code enough for a JNDI look up?? When I use this code, I get an exception:
"javax.naming.NameNotFound exception:jdbc/mybillingora"
Do I need to do something else??
Why do we use :
Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"<some_context_factory>");
env.put(Context.PROVIDER_URL, PROVIDER_URL);
env.put(Context.SECURITY_PRINCIPAL, JNDI_USER);
env.put(Context.SECURITY_CREDENTIALS, JNDI_PWD);
InitialContext = new InitialDirContext(env);
where JNDI_USER is the userid If ACL is configured at the JNDI server
where JNDI_PWD is the password If ACL is configured at the JNDI server
Context.INITIAL_CONTEXT_FACTORY is the initial Context factory and depends on ur JNDI service provider.
PROVIDER_URL is the url of the JNDI server containing protocol/ip/port
do i need to use this??
would appreciate your help on this....
Thanks
I am working on a pretty similar problem and posted my problem minute ago.
Include JNDI.jar from <Oracle_HOME>\jlib. (This is what I found in Oracle docs).
I presume you are also trying to create the Datasource using Datasource interface via JNDI rather than using Driver Manager.
Thanks

Hi ,
I am creating a POC for my project.Its using ATG and spring frameworks using RAD 6.first I have created ATG sample project in that same EAR file i created sample Spring project.Both are running in the same EAR.
I want to use spring classes from ATG components to use those methods.that is i should pass parameters to spring project methods and i should get the return value after executing those methods.
I heard that using JNDI look up I can get spring project class objects using that I can invoke spring project methods.
My requirement is two projects will be running in the same EAR.But one project will not be having information about other projects.both are independent from other.Using JNDI look up i need to invoke Spring project methods.
Please anyone help me how to do this.

How to use database look up table function in xsl mapping
Can anybody tell me how to use database look up table function while mapping xsl between 2 nodes.
I have an XML file coming in and depending on one of XML elements we need to decide which further path to take. But, using this XML element, we need to query database table, get metadata and accordingly take appropriate path. I have written lookup function which returns metadata value.
Now, the issue is how do I pass the XML element valu as input to look up function? When I tried to drag it to the input node of lookup function, it throws an error like "Maximum number of parameters exceeded"
Thanks,If the lookup table is always going to remain the same (e.g. a character generator or something similar) you can place the values in a 2D array constant on your diagram, with the input value as one column, the equivalent as the other. When you need to perform the lookup you use an index array to return all the values in the "input column", search it using "search 1D array" and use the resulting index number to index the other column's data. If the values may change, then it would probably be best to load an array control with your equivalent values from a file.

hi yesterday i downloaded a software from i tunes for keyboard short cut and i don't know how to use them and install them, how to use keyboard shorts bought from i tunes
You can install it on your iOS device (iPad, iPhone, iPod Touch) either by redownloading it directly on the device via the Purchased tab in the App Store app on it, or by connecting the device to your computer's iTunes and syncing it to it.
Syncing apps from a Mac : iTunes 11 for Mac: Sync and organize iOS apps
from a PC : iTunes 11 for Windows: Sync and organize iOS apps
As to how to then use the app, if the description on the app's description page in the store doesn't describe how to use it in enough detail, then is there a link to the developer's website on its description page, and does that have details ? -

How to use Sql data source from Essbase 9.3.1
Hi All,
How to use Sql data source from Essbase 9.3.1 for ASO cube.Are there any rules and limitations for that.
Do we need to create any data source connection for this purpose. If there please let me know the dteps to create that connection.
RegardsYes you need to create one DSN connection and you have to use DSN name and login details at the time of building/loading of the outline.
Create DSN
Goto Administrative tools -> DataSources (ODBC) and add the DSN name and specify the Server name of SQL and login details and database.
goto data prep editor and click on File Menu and Click on Open SQL option Next window opens.
There you have to enter the details of the DSN connection and SQL query to build/load.

How to retrieve the parameter names from a JSP page ? Urgent Please
Hello,
Can anybody tell me how to retrieve the parameter names from the JSP
page. (without using getParameterNames() method.)
The problem with the getParameterNames() method is I get the Jumbled output.
I need it very badly
With regards
Ananth R
email:[email protected]
[email protected]Dear duffymo,
My primary intention is to convert the JSP form information into a XML file.
If I do not get the Parameter names in the correct order how can I maintain
tag order in XML file.
For ex: (JSP PAGE VIEW)
Name--
FirstName
MiddleName
LastName
Address--
Street1
Street2
City
Country
&so on
(XML File to be generated)
<Name>
<FirstName>Value</FirstName>
</Name>
<Address>
<street1>value</street1>
</Address>
& so on
If I use getParameterNames() to get all the parameter names(Which form the tag names in the XML file ) the Enumeration object it returns will not be in the same order as the text fields in JSP.From this I can not construct a meaningful XML file.
order means: Order of entry on the page, from top to bottom
That's it

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.

How to use the pps function from JCOP?
Hi
I'm trying to use the pps function from JCTerminal (JCOP API: [url http://www.cs.ru.nl/~woj/jcopapi/com/ibm/jc/JCTerminal.html#pps(int, int)]pps function ) to connect my client to a virtual card with a specific protocol (T=0).
But I always got the error: "Protocol and parameter selection not supported by this terminal!"
I've tried to make an ATR that support both protocol : [url http://smartcard-atr.appspot.com/parse?ATR=3b909580811fc7dc]3B 90 95 80 81 1F C7 DC.
I really don't know what value to put in the second parameter (baud rate), I've tried with 150000, which is in the range of the ATR but I'm not sure this is correct. And I could't find any example of it.
I'm also not sure where to put the pps command, the specification say directly after a reset, so I tried this implementation:
System.out.print("Start");
readers = TerminalFactory.getDefault().terminals().list(State.CARD_PRESENT);
//If no readers has a card it ends the process
if(readers.isEmpty()){
System.out.println("\nNo card in the reader...");
return;
System.out.println("\nReader Type: "+readers.get(0).toString());
term = (PCSCJCTerminal)JCTerminal.getInstance("PCSC", readers.get(0).toString().substring(15));
term.open();
System.out.println("\nTerminal opened");
//Getting the ATR
atr = new ATR(term.waitForCard(2000));
try {
term.pps(JCTerminal.PROTOCOL_T0, (int)150000);
} catch (Exception e) {
e.printStackTrace();
System.out.println("ATR: "+toHex(atr.getBytes()));
//sending a data 11223344
System.out.println("\nsending data: 11223344");
byte[] responsesend = term.send(0,cmdsend,0,cmdsend.length);
System.out.println("Response data is:" + toHex(responsesend));
//close terminal
term.close();
System.out.println("\nTerminal closed");I've got this output on the console:
<font size="2">StartReader Type: PC/SC terminal Virtual CAD Reader 0
Terminal opened
ATR: 3b 90 95 90 00 81 1f c7 cc

I'm using a virtual terminal (windows driver), and I don't see how I could turn off the Auto-pps. I've also tried with a real reader and a card and I have the same error.

I've tried value in the range of the atr (based on this analysis: [url http://smartcard-atr.appspot.com/parse?ATR=3b909580811fc7dc]http://smartcard-atr.appspot.com/parse?ATR=3b909580811fc7dc ). But I don't know if only I value of baud-rate is possible in the range. Anyway I just would like to change the protocol, not the baud-rate.

I've already tried to call pps function before, after the first reset, or with another reset later and I always got the same thing.

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,
SIf 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.
