Does OC4J support RMI/IIOP connections ?

Hi,
I have only one question :
Does OC4J support IIOP connections ?
I'd like to connect as EJB client to OLAPService on Oracle9i server (CORBA object), but I can't.
Thanks in advance

Thanks for your timely post Debu.
I would like to state that I read and followed the guides (same files as those ponted by the links you just provided) and tried this:
1. Sample J2EE Application using ORMI in OC4J Standalone (this works ok)
2. Same but now using ORMIS (this also works fine)
3. Tried same J2EE App using IIOP; took these steps:
3.1 commented out the rmi.xml security lines,
3.2 enabled ports in internal-settings.xml,
3.3 changed the jndi.properties - now using corbaname URL,
3.4 enabled the IIOP stub generation in the JVM settings at oc4j startup, and finally
3.5 deployed the EAR using the generateIIOP flag.
The result: the exception I posted above
4. Tried with IIOP/SSL, did these steps:
4.1 configured the keystore settings in both internal-settings.xml and ejb_sec.properties
4.2 and added <ior-security-config> config elements to orion-ejb-jar.xml.
The exception here is a little bit different:
client started...
In IIOPInitialContextFactory ..
In IIOPInitialContextFactory getInitialContext..

How to configure OC4J using RMI/IIOP with SSL

Any help?
I just mange configure the OC4J using RMI/IIOP but base on
But when I follow further to use RMI/IIOP with SSL I face the problem with: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
p/s: I use self generate keystore which should be ok as I can use it for https connection.
Any one can help?
Below is the OC4J log:

Good point, I do belive what you are referring to is this:
Any client, whether running inside a server or not, has EJB security properties. Table 15-2 lists the EJB client security properties controlled by the ejb_sec.properties file. By default, OC4J searches for this file in the current directory when running as a client, or in ORACLE_HOME/j2ee/home/config when running in the server. You can specify the location of this file explicitly with the system property setting -Dejb_sec_properties_location=pathname.
Table 15-2 EJB Client Security Properties
Property Meaning
# oc4j.iiop.keyStoreLoc
The path and name of the keystore. An absolute path is recommended.
# oc4j.iiop.keyStorePass
The password for the keystore.
# oc4j.iiop.trustStoreLoc
The path name and name of the truststore. An absolute path is recommended.
# oc4j.iiop.trustStorePass
The password for the truststore.
# oc4j.iiop.enable.clientauth
Whether the client supports client-side authentication. If this property is set to true, you must specify a keystore location and password.
# oc4j.iiop.ciphersuites
Which cipher suites are to be enabled. The valid cipher suites are:
TLS_RSA_WITH_RC4_128_MD5
SSL_RSA_WITH_RC4_128_MD5
TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA
SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA
TLS_RSA_EXPORT_WITH_RC4_40_MD5
SSL_RSA_EXPORT_WITH_RC4_40_MD5
TLS_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA
SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA
nameservice.useSSL
Whether to use SSL when making the initial connection to the server.
client.sendpassword
Whether to send user name and password in clear form (unencrypted) in the service context when not using SSL. If this property is set to true, the user name and password are sent only to servers listed in the trustedServer list.
oc4j.iiop.trustedServers
A list of servers that can be trusted to receive passwords sent in clear form. This has no effect if client.sendpassword is set to false. The list is comma-delimited. Each entry in the list can be an IP address, a host name, a host name pattern (for example, *.example.com), or * (where "*" alone means that all servers are trusted.

Yes Clinton I did same, but they were (Huawei customer support) surprised about this problem, They behave like they have no idea about USB 2.0 and 3.0 knowledge. They handsUp that reason I posted my problem in this forum.
So is there any better solution to use any mediator between these USB version handling, Please let me know.

It appears that Adobe Air does not support persistent HTTP connections?

As far as we can tell, Adobe Air does not support persistent HTTP connections via KEEPALIVE
Thus a new connection has to be established to the server, making certain types of network intensive applications slow.
Can anyone confirm if this is correct - is there any way to get Adobe Air to support KEEPALIVE and maintain persistent server connections?

Losing RMI-IIOP connection at server end

Hi all
I have a system running on Solaris 9, JVM 1.4.2_06 with a webapp hosted in Tomcat 5.5 connecting over RMI-IIOP to another java service on the same machine. The connection is established at webapp initialisation via a lookup to the naming service (currently tnameserv).
Unfortunately, after a period of time (varies between a few hours and a couple of days), the RMI connection simply disappears from the server-side point of view, and the webapp grinds to a halt. Taking a thread dump of Tomcat and the service at the point of failure shows that Tomcat still has "JavaIDL Reader" threads listening to the service, but the service has lost all of its "JavaIDL Reader" threads listening to Tomcat.
I've traced the problem as far as line 518 of com.sun.corba.se.internal.iiop.messages.MessageBase:
bytecount = is.read(buf, offset + n, size - n);This read on the InputStream is throwing an IOException. I have configured the system so that IP address 127.0.0.1 is being used in all places.
It may well be that this is not the right forum for this question, but has anyone else ever come across a problem like this? All suggestions most welcome.
Regards
Brian

In trying to find an answer to your question, have actually discovered that the root cause of the issue is actually a little lower in the stack.
SocketInputStream.read(byte[],int,int) is returning -1 (EOF), and this is being interpretted into an IOException by the MessageBase class. So now I need to work out why this unexpected EOF may be occurring on this platform.
I imagine this is no longer very relevant to the RMI forum. I've posted on the Socket Programming forum.

Brian

Does OC4J support soap attachments???

If yes where can I find the api???
Is it the same as apache soap? someting like message.add/getAttach(mimebodypart)?
Does the wizards handle it?
TAD

You can use Oracle SOAP services to send attachments with SOAP request.
Refer documentation on Oracle9iAS SOAP services here
http://otn.oracle.com/docs/products/ias/doc_library/903doc_otn/generic.903/b10004/oraclesoap.htm#640260
You can look at the sample services described here
http://otn.oracle.com/docs/products/ias/doc_library/903doc_otn/generic.903/b10004/oraclesoap.htm#643327
The samples.jar referred in above doc can be found in in
<OC4J_Home>\soap\webapps\soap.ear =>soap.war =>samples.jar
The Mime Sample demonstrates SOAP with attachment

Does 9iAS support Javascript DB connection?

Just wondering if there is a way to make an Oracle database connection in Javascript through Apache. Netscape server has equivalent functionality, called LiveWire or Server-Side javascript. Anything like that in 9iAS?

Thanks shmooth!!
I did check out Apache, and I found it--posting here in case anyone else is interested.
There is a new module in early (1.0) development stage called XANG. It combines XML and Javascript to create a server-side, database-aware scripting environment. Probably too early for my purposes, but those of you with more bravado may wish to download. It should work w/9i AS since it's just another module (note "should").
URL is
http://xml.apache.org/xang/

Does Hibernate supports multiple schemas connection ?????

i want to connect to multiple schema's on the same data base using
hibernate...
my hbm.xml looks like this
<hibernate-mapping>
<class name="SampleClass" table="SampleTable" schema="DynamicSchema">
</hibernate-mapping>i need to enter the schema name as parameter
and change it dynamically....
is this possible or are there another way in hibernate ???
thanks in advance and
some code wouldn't kill any one :)

To set schema dynamically the org.hibernate.mapping.Table class has a method setSchema(String)

EJB client connection [RMI/IIOP]

1) Just to test the communication between EJB client and EJB using RMI/IIOP in WLS 9.2, I have created two InitialContexts and I have seen that here are only two InitialContext. But, I can see only a single connection displayed (Monitoring Channels tab for the default [IIOP] channel). Is this expected? Doesnâ€™t is suppose to create two connections?
2) If only one connection is established. What is the way this model will scale up?? I can have multiple calls..right?
3) What is the connection time out works on this? If I have a stub cached. Does that mean my RMI/IIOP connection still be alive?

RMI-IIOP and glassfish naming service

I have some very basic test applications to test RMI-IIOP. The applications are one server (registers the Remote object) and one client (tries to retreive the remote object stub and invoke a simple hello() method).
I've been trying to get it to work by registering the Remote object (see below) in glassfish naming service (JNDI) but I get the following an error saying: "Class rmi.ListenerRemoteImpl not exported, or else is actually a JRMP stub". I haven't been able to figure out why...
Then I found another guide which I followed and managed to get to work. The only difference there was that I used orbd as naming service.
Why is this? Doesn't Glassfish JNDI support RMI-IIOP in this way?
Any help is greatly appreciated!
I followed the following steps in creating the application:
-Created the following classes:
Client.java //The client
Server.java //The server
ListenerRemote.java //Remote interface implementing Remote
ListenerRemoteImpl.java //Implemtation extends PortableRemoteObject and implements ListenerRemote
-Generated stubs with rmic using -iiop
-Compile and run...

Here is some of the code...
Client that fails with glassfish but not with orbd:
=========================================
public static void main(String[] args) throws Exception {
ListenerRemoteImpl listener = new ListenerRemoteImpl();
Properties props = new Properties();
props.load(new FileInputStream("jndi.properties"));
//Uncommenting this and starting orbd makes it work. When default jndi.properties from Glassfish is used, it does not work.
//props.put("java.naming.factory.initial", "com.sun.jndi.cosnaming.CNCtxFactory");
//props.put("java.naming.provider.url", "iiop://localhost:1060");
Context ctx = new InitialContext(props);
ctx.rebind("listener", listener);
System.out.println("Listener bound!");
==================================
ListenerRemoteImpl:
==================================
public class ListenerRemoteImpl extends PortableRemoteObject implements ListenerRemote {
public ListenerRemoteImpl() throws RemoteException {
super();
public void sayHello() throws RemoteException {
System.out.println("Hello!");
==================================
