What's missing here?

http://java.sun.com/j2se/1.4.2/docs/api/javax/naming/Context.html
maybe you should set the property:Context.INITIAL_CONTEXT_FACTORY
try that.

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

Hi!
I got this error message at runtime.
After adding value to the Intialcontext by adding the following code snippet:
Properties p = new Properties();
p.put("java.naming.factory.initial",
"com.sun.jndi.cosnaming.CNCtxFactory");
p.put("java.naming.provider.url",
"iiop://127.0.0.1:9010");
initContext = new javax.naming.InitialContext(p);
After this i am getting different error message:

Jndi properties in InitialContext : java.naming.factory.initial

I am trying to lookup a bean with the following code. I get a NamingException on line 9 when the jndi properties are referenced. The exception message that I receive is "Cannot instantiate class: org.jnp.interfaces.NamingContextFactory". Does anyone know what the problem may be?
1 // Set the jndi properties
2 Properties jndiProps = new Properties();
3 jndiProps.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
4 jndiProps.setProperty("java.naming.provider.url", "localhost:1099");
5 jndiProps.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
6 try
7 {
8 Context ctx = new InitialContext(jndiProps);
9 homeMyBean = (LocalMetricResultsHome) ctx.lookup("MyBean");5
10 }
11 catch (NamingException e)
12 {
13 // handle namingexception
14 }

It means the .jar file containing that class is not in your ClassPath. Try putting jnp-client.jar into your ClassPath.

Java.naming.ORB system property

Hello,
In my program, i want to set java.naming.ORB system property to the ORB that is already initialized. Is there any way to do this ??

What does the word Factory mean in "naming factory "

What does the word Factory mean in "naming factory" in JNDI tech?

A Factory class is a class that produces an instance of an object. For example, a ParserFactory class will have a method that returns a Parser. Usually this Factory class is looking at something in the environment to decide which object to return. "Factory" is just one of many "Design Patterns" that you will encounter in the programming world. Several (many?) books have been written about design patterns.

How to set java.naming.provider.url when multiple oc4j instances in iAS

Hi Folks,
I have problems engaging a connection to a deployed application in a 9.0.3 iAS instance. I created 2 oc4j instance within the iAs instance.
I wonder how to set up the JNDI provider url?!?
According http://download-west.oracle.com/docs/cd/A97329_01/web.902/a95879/jndi.htm
the provider url contains of ormi://host:port/application.
Unfortunatly I get a connection refused Naming Exception.
What's wrong?
Where can I look up the
java.naming.security.principal
java.naming.security.credentials
Are they set by default?
I tried the following scenario:
java.naming.provider.url=ormi://host/oc4j-instance/application/
and a user/password from principals.xml in the application/config directory, but don't have any success.
So please help me ;-).
Bye & Thx
Toby

This is correct as far as aI remember
1) java.naming.provider.url = t3://server1:port1,server2:port2
see

Java naming Convention

Hi all,
I urgently needed your assistance on advice regarding the java naming convention.
i am in the middle of creating a interface class and a implementation class
BusinessAccountIF
and
BusinessAccount
However, I been told is very bad ideal to use the word IF in the ending of interface.
Technical we don’t need to, but I always like my code to be tidy,
hence using the IF in the end of the interfaces class.
Please do let me know what your thought??

Please do let me know what your thought??As others have said: keep your names as descriptive as possible.
I would expect an interface called 'BusinessAccount' (which seems perfectly sensible to me) to be extended from an interface called 'Account', and have implementing classes that describe a specific type of business account (eg, 'DepositAccount', 'EquityAccount', 'AssetMaintenanceAccount'), possibly via a "skeleton implementation" class, which by convention, is usually called 'AbstractBusinessAccount'.

Finding intial context factory for java naming connect to DS5

I'm a newbie to LDAP programming using the JNDI interfaces to connect to my
DS 5 implementation. I can't seem to find any reference as to where the
correct factory for the initialDirContext is! I need the factory classname
for this call:
env.put(Context.INITIAL_CONTEXT_FACTORY,"factory classname goes here");
which is neccesary to set the initialDirContext.
As far as I can tell there is no default context for an LDAP connection that
would make this easier and I don't know where or if I can find one remotely
located on my DS5 box.
Any help would be appreciated,
-Jake

Creating a Java named query?

Hi,
From the application developers manual; is it implied that named queries can be created using the Oracle Toplink API in Java; i.e out of the workbench but I have not been able to find any references to this elsewhere. Does anyone have any information on this? i.e creating the named query in Java code and then adding it to the project deployment.
In addition, is it possible to have it such that if a named query expects 4 arguments; the Java code is written to check if there are any null values passed in, and if the values are null those columns wlil be removed from the query.

There are really two types of queries that apply.
Named queries being those queries defined in Java code at application start up that take a fixed number and types of parameters. These queries are typically added using descriptor after-load methods. In the MW you select the static after-load method where you wish to define your queries. As of TopLink 9.0.4 it is possible to define your named queries with arguments directly in the MW without an after-load method.
Redirect queries are queries where TopLink invokes your method at runtime to execute the query. This approach allows for your code to selectively build the where clause based upon the arguments passed in.
Some links into the docs that may be of interest:
after-load: http://download-west.oracle.com/docs/cd/B10464_01/web.904/b10316/dscriptr.htm#1014978

Java SP's - Initial Load Time!

FYI, We are running Oracle 8.1.7 on HP/UX 11.0 using Java Stored Procedures.
The Java stored procedures work fine (sub-second performance) after being loaded into memory, but the initial load time can be anywhere from 2 to 3 seconds. When you have 30+ Java stored procedures, the initial startup causes table locking and contention that will cause our app to crash.
Rewriting these Java SP's in PL/SQL shows that PL/SQL is immune to this initial load time (to a much lesser degree). Besides rewriting my application to read all of the Java SP's into memory before app startup, is there anything I can do on the Oracle server side to improve (or eliminate) load times for Java Stored Procedures?
Thanks!

Hi Sonja,

     assignedroles     $FUNCTION.sap_getSPMLRoles(%MSKEY%!!%$rep.$NAME%!!pcd:portal_content/every_user/general/eu_role)
I have no idea what's wrong in here...
Maybe you or someone else can help me...?!

Java Applet not Initializing (LMS)

Hello everyone,
I have a small problem when trying to access a Java applet screen. When I open the applet, there are two different portions of the screen, a left window and a right window. In the left window, there is a caption at the top that says "LMS Initializing". There is supposed to be a list of hyperlinks that populate in the window, but they never do. It hangs on the LMS.
What is LMS? Something is blocking it's initialization. I have checked the manage add-ons menu and verified that the Java is plugged into IE, but I cannot seem to figure out the issue.
I do know of the following issues as well, and I have verified that they are not the problem here:
*Popup blockers
*IE security settings under the "Security" tab in Internet Options
*Secure Socket Layers
If anyone else can give me a boost here, I would appreciate it. Thanks!

did you restart the forms server with the command.
$ADMIN_SCRIPTS_HOME/adopmnctl.sh stopall
$ADMIN_SCRIPTS_HOME/adopmnctl.sh startall

Java Applet not initiating

I'm new to Java and have been going through the SAMS "Teach Yourself Java 2" and have a problem will Applets. I am using the latest download of Java2SE (J2sdk1.4.2_09) and NetBeans IDE.
Creating Java programs works fine but when I do the exercise for Applets called "Palindrome" project, it fails. I embed the <APPLET> tag in my HTML a couple different ways laid out in the text but all fails. I doing this without the Internet. Is there something special that I need to do to get this to work with the generated palindrome.class on my hard drive.
I did make some changes to my computer's Internet settings based on an FAQ I saw on the Sun site - Proxy_Server - localhost. But this did not solve my problem.
I would appreciate any suggestions on how I might further investigate this - I'm sure I have something set wrong and just need some more test options to identify the problem.
Your assistance is greatly appreciated.
Thanks

please if any one can explain me this tags as I don't know HTML.

Thank for Gussing actually there is a method in the application which take String as a parameter.name of the method is createState(String message) .I thik they have written wrong code by adding State ("string")

Along the same line, one thing that irks me is that eclipse keeps suggesting

Color.BThe horror!
