How to Bind EJBs under COS Naming Service

Hi,
I want bind EJBs under COS Naming serices and
how to lookup those EJBs from java clients.
I am using Weblogic 5.1.
thanks,
-Ramesh

Can you give a complete example of this? I'm having the same issue. We
have CORBA clients that we want to redirect to EJB implementations
instead of ORB servers. How do I bind the CORBA objects in CosNaming?
The example provided with WLS seems to cover RMI/IIOP but doesn't cover
CORBA client to EJB.
Thanks,

How to Connect to the Visibroker Naming Service using the Servlet

Hi
I am facing Problem in finding the Initial JNDI Context.
It is giving me ClassCastException.
In our Application the Tomcat is Integrated with One of the Partitions. And the EJB' are registered on Visibroker Naming Service (on the same machine).
I want to Access one of the EJB's.
Following is my Client Code in the Servlet.
==============================================================================
public void doPost(HttpServletRequest request, HttpServletResponse res)
throws IOException, ServletException
res.setContentType("text/html");
PrintWriter pw = res.getWriter();
pw.println("<html>");

Ankit

You can check whether any cookies were sent in the request to your servlet:
Cookie cookies[] = request.getCookies();
if cookies is not null (cookies != null) then the browser sending you the request suppoerts cookies.
If it is null then you would need to do a little extra work. Basically add a cookie to the response going back to the browser. Then send a redirect back to this same servlet. You then would have to add code to check to see whether the cookie was sent back.
// Servlet named myServlet
String test = request.getParameter("TEST");
Cookie cookies[] = request.getCookies();
if (test == null || !test.equals("TRUE")
if (cookies == null)
response.addCookie("testCookies","testCookies");
response.sendRedirect("myServlet?TEST=TRUE");
else
// cookies were sent in the initial request, so
// browser supports cookies
else
// This is the redirect. Check the for the presence of
// our testCookie
Hope this helps.

How corba client and server find Naming service

hello
i want to ask how corba client and server find the Naming service ?
10x

By using a well-known port (I think the default for JavaIDL's NS is 1049) on a well-known address (localhost).
As these values are not really standard, you can specify them when starting the server and client (+-ORBInitialPort 1050 -ORBInitialHost localhost+). See the documentation .

How to bind list data to XML Web service request

How do I bind specific columns in a DataGrid to the Web
service request? I'm having trouble finding any documentation that
addresses that specific pattern, i.e. sending a complex list to the
server via a Flex Web service send() command. I'm fairly new to
Flex programming and don't know if what I want to do is possible.
Here what I've been able to do so far.
1. Using a Web service called a service on the server and
retrieved a complex list.
2. Poplulated a DataGrid with the result
3. The user has selected multiple rows from the DataGrid
using a checkbox column
4. The user pressed a button that calls a Web service send().
This Web service should only send data from only two columns and
only for those rows the user has checked.
5. I can loop over the DataGrid and find the selected rows
and put them in another ArrayCollection called 'selectedRows'.
The issue is that I don't know how to bind 'selectedRows' to
the Web service. Right now I'm reading up on "Working with XML" in
the Programming with ActionScript 3.0 chapter. But I'm just fishing
here. No bites yet.

Don't bind. Build the request object programatically, as you
are doing with your selectedRows AC, and send(myObject) that.

Cos Naming & WLS Naming Service problem in distributed Tuxedo application

Hi,
we have been starting our investigation into using the distributed application feature of Tuxedo (multiple machines running under 1 Tuxedo domain which make up the entire Tuxedo Application).
when trying to access WLS EJB object references from Tuxedo, we hit a road block.
we have been using the standard method of searching through Cos Naming for a bind context which refers to WLS Naming Service. (this method is documented online and in dev2dev samples) Under non distributed application setup (1 Tux domain with 1 machine as in all examples), everything works fine and I can see into 1 WLS server's JNDI tree. But when in distributed application setup where we want to have two (for example) machines and we also want two WLS managed server with each running on their own machine, it seems that there are some unexpected problems:
1. - only one set of GWADM/GWTDOMAIN is running
- each WLS managed server has its own WTC server
- each WTC server has its own LOCAL ACCESS POINTs
- each WTC server uses the single REMOTE ACCESS POINT
(since only one GWTDOMAIN is running in this scenario)
--> problem: only one of the managed server's JNDI tree can be traversed into, and only one of the WTC link works for Cos Naming -> WLS Naming Service resolution
2. - each machine is running their set of GWADM/GWTDOMAIN
- in dmconfig, two local Tux domain-ids are defined, for the
two groups of GW
- WTC server setup is identical to above; except
each of the WTC is pointing to separate REMOTE ACCESS POINTs
- when DOMAINID in ubbconfig is not defined, the same Cos Naming to WLS Naming Service search fails.
- when DOMAINID in ubbconfig is defined, the same Cos naming to WLS Naming Service search fails with an CORBA:INTERNAL error.
Does anyone know how to get Cos Naming -> WLS Naming Service working properly under a distributed Tuxedo application setup and also with multiple sets of GWADM/GWTDOMAIN?
Thanks.

How to keep multiple function modules under one Web service

Hi Experts,
I have Three RFC function modules and i need to create one web service for these three RFC function modules. I know How to crearte a web service for one function module.
please suggest me How to keep multiple function modules under one Web service.
Thanks in advance
Lakshminarayana

Hi Lakshmi,
The best way to do it is to assign all the three RFC Enabled FM's to one function group. Later on the top menu in Utilities you get an option to Create a Webservice from a Function Group.
You can create one single Webservice using all the the 3 FM's.
I hope this helps.

How to bind complex input/output types in web service data control

Hi,
I have created data control using external web service for simple input & output data type and its working fine.
But I don't know how it can be done for complex data types.
My external Web services have complex input & output types. Such as java object which contains another java object again it contains another java object or arry or java collection etc.
Each my service has one complex input data type and for this no user input is require so how I can do it without using any component for it.
I want to bind my page components with this input & output type.
What is the best approach to do this and how to bind screen component.

How to run Naming service in WebAs server using telnet

Hi
i have a requirement to start a naming service in WebAs server.I have seen all the services running in server using telnet.But i haven't find naming service.So i have to start it.so pls send me the command and the way how to start it.

Hello Bhogi,
The naming service is a core service so it should always be started. You can check it via telnet using lss command on the server shell or in the visual administrator if you navidate to server-> services -> JNDI Registry.
I suspect that you have not seen the naming service via telnet as you were on the dispatcher node instead of on the server.

How to bind to REST web services?

The REST web services don't provide WSDL. How to bind this kind of services?
Thanks.

Melvin, not yet (in fact it's on my plate) - what I usually argue for is to abstract these pieces into services (much like what I did in the rest sample, and then expose them .. )
In any case - I will start collecting ideas (that is topics) for best practices soon .. Let me know if you have any specific wishes.

JNDI Naming services

Im currently working on some code and Im really in need of a naming service, preferably one with a service provider for JNDI. In essence what Im looking for is a very basic name server, although knowing little about the suject at this point Im thinking that ldap, nis are really not well suited to my needs as my key goal is mapping names to references( under dynamic contexts), which Ive allready half implemented. As things are getting more complex and what Ive implemented of rather poor design, Im starting to feel like Im going to have a rough month or two ahead of me!! I dont want to re-invent the wheel and I know in my heart someone has allready coded the software I need!!! Unfortunately My search has been fruitless. Id greatly appreciate it if someone can steer me in the right direction. In the meantime I think Ill be pulling my hair out trying to figure out how to code the software I need.... Sorry for not fully explaining what Im after, if not enough info just let me know and Ill try to provide more detail.............

Hi Prisco,
You can go very well fo JNDI. And you can use Netscape or Iplanet Directory server as LDAP server.
Please Download the Directory Server from this URL.
http://www.iplanet.com/downloads/download/2087.html
Also here with I am giving you a simple Authentication program, which makes use of JNDI and Netscape Directory server. If you follow these steps, you will get a good idea about JNDI.
DESCRIPTION:
I am trying to use LDAP to control access to a HTML page. I want an authentication
box to pop up, allowing the user to authenticate to the HTML page through a LDAP server.
If they succesfully authenticate, I need to check their username against a list
of valid usernames that's stored in a database, then give access to the page
based on that list. How can I implement this solution?
SOLUTION:
The best way is to use Basic Authentication solution with JNDI and LDAP server,
Netscape Directory server(for example) with a simple servlet program. Java Naming
and Directory Interface (JNDI) API is standardized, and enable to use different
directory services such as Netscape Directory server. LDAP server can be used
for storing some common data's used in the sample solution.
It can be done through a servlet to check the user and its password which is
stored in the LDAP server.
In order to demonstrate a sample solution, I will use the Netscape Directory
Server 4.13 as the LDAP server, which is loaded my own LDIF file with customized
attributes. The basic authentication algorithm will be used in this sample
solution.
The following steps are to implement this sample solution:
1. Creating our own LDAP data Interchange format (LDIF) file.
2. Loading(Import) the Ldif file in Netscape Directory Server.
3. Creation of user schema files for customized attributes.
4. Load the user schema files in the Netscape Directory Server.
5. Restart the Directory Server
6. A simple servlet program for basic authentication.
7. A sample HTML file is given last, used in servlet program.
Here are the detail description of the above steps:
STEP 1: Creating our own LDAP data Interchange format (LDIF) file:
Here is the LDIF (LDAP data Interchange format) file is a text based format used to work
on LDAP data, with both our application and end users.
Through this LDIF file, I am having an attribute "customerid: timb" for which I will
be preparing the authentication, which will have its own password
"userpassword: bakrudeen", through which it can be maintained in a common place.
Here again in the same LDIF file, other information related to the "customerid: timb"
such as common name "cn: Tim Briggs", sur name "sn: Briggs" etc are maintained.
The data in LDAP is organized in a tree, called a Directory Information tree(DIT).
Each leaf in DIT is called an entry. The first entry in DIT is called the root entry.
Here is a sample LDIF File which is used in our sample solution:-
Here the DIT is maintained in such a way data is organized in LDAP, is fairly simple. In this
sample we store all of our entries in a common root o=fedup.com, with the following branches
Customers - Customer Entries with " customer id: timb" , userpassword: bakrudeen, and other
information related to this customer is kept in a common place.
dn: uid=timb,ou=Customers,o=fedup.com
changetype:add
objectclass: customer
objectclass: inetorgperson
objectclass: organizationalPerson
objectclass: person
objectclass: top
cn: Tim Briggs
uid: timb
givenname: Tim
customerid: timb
sn: Briggs
facsimiletelephonenumber: 4101
telephonenumber: 4145
creatorsname: uid=admin,ou=Administrators,ou=TopologyManagement,o=NetscapeRoot
createtimestamp: 20000501084001Z
aci: (target="ldap:///uid=timb,ou=Customers,o=fedup.com")(targetattr="*")(version 3.0; acl "unknown"; allow (all)(userdn = "ldap:///anyone");)
ou: Customers
mail:
userpassword: bakrudeen
modifiersname: uid=admin,ou=Administrators,ou=TopologyManagement,o=NetscapeRoot
modifytimestamp: 20000605084001Z
STEP 2: Loading(Import) the Ldif file in Netscape Directory Server:-
Once after creating the above sample LDIF File, it should be added in Netscape Directory Server.
It should be imported in order to add the neccessary atributes in the Netscape Directory server,
so that we can make use of the Common data.
Steps for Importing the LDIF file in the Directory Server:-
1) Create an instance of the Directory Server.
2) Bind it to the different port with different organizational unit
(Here in this program, it is 1124).
3) Press the Configuration from the menu.
4) Then select import from the Console menu.
5) Choose the LDIF file you are going to import.
6) There also you have to provide a file for rejected entries, ie it will list all the entries
which is not added while loading.
STEP 3: Creation of our own USER SCHEMA Files:-
It is necessary for adding the attributes which are not defined in the
Netscape directory server. In the above, customerid which is defined in ldif
file is not existing in the directory server.
Here is the Schema file for attributes:(ie for defining for eg customer id).
The name of the file is slapd.user_at.conf:-
attribute customerid customerid-oid cis single
attribute packageid packageid-oid cis single
attribute receivedate receivedate-oid cis single
attribute shipdate shipdate-oid cis single
attribute shipperid shipperid-oid dn single
attribute receiveid receiveid-oid dn single
#Java Attributes
# Schema for storing java objects and java object references
attribute javaClassName 1.3.6.1.4.1.42.2.27.4.1.1 ces single
attribute javaCodebase 1.3.6.1.4.1.42.2.27.4.1.6 ces
attribute javaSerializedData 1.3.6.1.4.1.42.2.27.4.1.7 bin single
attribute javaRemoteLocation 1.3.6.1.4.1.42.2.27.4.1.8 ces single
attribute javaFactory 1.3.6.1.4.1.42.2.27.4.1.4 ces single
attribute javaReferenceAddress 1.3.6.1.4.1.42.2.27.4.1.3 ces
Here is Schema file for your own object classes:-
The name of the file is Slapd.user_oc.conf:-
In the similar way as above there are no "customer" class in the object classes
defined in the LDAP, so we will have to create our own "customer" Object class.
Also it extends inetOrgPerson to add some new attributes such as "customerid".
The object class of an entry specifies what attributes are required and what
attributes are allowed in a particular entry.
Also for eg, Package classes in the object class is created.
Here is the sample file for creating the above:-
objectclass package
oid package-oid
superior top
requires
packageid,
receiveid,
shipdate,
shipperid
allows
description,
ou,
receivedate
objectclass customer

objectclass javaNamingReference
oid 1.3.6.1.4.1.42.2.27.4.2.7
superior javaObject
requires
javaReferenceAddress,
javaFactory
STEP 4: Loading the USER SCHEMA files in Directory Server:-
All the attributes created above should be added to the corresponding directory server,
in order to make it as a common attribute.
Steps for adding the User Schema files to the Directory Server:-
1. Copy the above user schema files to the appropriate instance of Netscape Directory Server
created above so that the existing LDIF file which is used in the Netscape directory
server is not appended or overwritten.
2. For eg, put it in "NetscapeServer/slapd-HostName/config" to replace the empty
files "slapd.user_at.conf" and "slapd.user_oc.conf" by default.
3. Then restart the Directory Server.
STEP 5: Simple Servlet Program for BASIC AUTHENTICATION.
Here is the simple servlet program for Basic Authentication:-
Here the way the LDAP authentication works is by attempting to the server with a
DN and a password. No user in their right mind will remember their DN, so we use
some other attribute such as user-id. Then we search in the LDAP server to find
an entry that contains the attribute. Here we are maintaining SUBTREE_SCOPE using
JNDI, which starts its search starting from the base entry, and searches
everything below it including the base entry. Also I am maintaining Global
variables for LDAP setting.
// Importing the necessary Packages
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.naming.*;
import javax.naming.directory.*;
public class AuthServ extends HttpServlet {
// Here are our global variables of our LDAP Settings.
public static String MY_CUSTOMER_BASE = "ou=Customers,o=fedup.com";
public static String INITCTX = "com.sun.jndi.ldap.LdapCtxFactory";
public static int MY_PORT = 1124;
public static String MY_HOST = "ldap://sundts1.india.sun.com:" + MY_PORT;
public static String MY_MGR = "cn=Directory Manager";
public static String MY_PWD = "password";
public static String MY_SEARCHBASE = "o=fedup.com";
Hashtable env = new Hashtable();
// Using the Get Method of Servlet
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.setContentType("text/html");
// To Check to See if there is any data in the "Authorization" Http header from the browser.
// If not it will prompt for username and password.
String auth = req.getHeader("Authorization");
// Do we allow the user
if (!allowedUser(auth) ) {
// Not Allowed, so report unauthorized
res.setStatus(res.SC_UNAUTHORIZED);
res.setHeader("WWW-Authenticate", "BASIC realm=\"users\"");
// User is allowed in
else
// Using SSI to include and display the content of a Simple HTML Page
RequestDispatcher rd= this.getServletContext().getRequestDispatcher("/auth.html");
rd.include(req,res);
// This method checks to see whether the user exist in the LDAP database.
protected boolean allowedUser(String auth) throws IOException {
Hashtable env = new Hashtable();
boolean status = false;
try {
// No Authorization
if (auth == null) return false;
// Basic Authentication is Handled, Other possibilities are MD5 hash or SSL Certificates.
if (!auth.toUpperCase().startsWith("BASIC ")) {
return false; //only do BASIC
// Get encoded user and password, comes after BASIC
String userpassEncoded = auth.substring(6);
// Decode it, using any base 64 decoder
sun.misc.BASE64Decoder dec = new sun.misc.BASE64Decoder();
String userpassDecoded = new String(dec.decodeBuffer(userpassEncoded));
StringTokenizer st = new StringTokenizer(userpassDecoded,":");
String customerid = st.nextToken();
String pwd = st.nextToken();
Please Note:
LDAP Authentication works by attempting to bind to the server with a DN and a password.
No user will remember their DN so we use some other attribute such as user-id.
Then we search in the LDAP server to find an entry in the LDAP server to find an entry
that contains the attribute.
For a Secure System, we should use an attribute that will be unique per entry such as
uid, in our case the "customerid" attribute.
// Prepare for context
env.put(Context.INITIAL_CONTEXT_FACTORY, INITCTX);
env.put(Context.PROVIDER_URL, MY_HOST);
// Get a reference to a directory context
DirContext ctx = new InitialDirContext(env);
// Specify the scope of the search
SearchControls constraints = new SearchControls();
constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
// Perform the actual search
// We give it a searchbase, a filter and the constraints
// containing the scope of the search
NamingEnumeration results =
ctx.search(MY_CUSTOMER_BASE, "(customerid=" + customerid + ")", constraints);
String dn = null;
If it does not throw an exception,
then it is considered to be an Successful Authentication
// Now step through the search results
while (results != null && results.hasMore()) {
SearchResult sr = (SearchResult) results.next();
dn = sr.getName() + "," + MY_CUSTOMER_BASE;
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, dn);
