Support multiple clients.

hi, all
I have some ideas on it and want to see if it makes sense. May you share your experience/expertize? thx in advance.
The target is to support multiple clients in one server. It uses TCP socket. The design choices are:
1. Uses one ServerSocket for one client. starts a new thread for each ServerSocket.
2. Uses one ServerSocket for all clients. everytime accept() returns, starts a new thread for this client.
I think #2 is better since it uses one port number and less resources.
Any ideas?
thx
Tim

You're welcome. I posted an example on a Multithreaded Server that does this, it actually uses two threads per client to provide full duplex support.

Thanks!

well, since I feel kinda bad for just re-posting the link to the API docs previously posted by supermicus I shall elaborate - though, since my reading for comprehension skills are clearly lacking, I will not attempt to teach you to read.
This conversation should be held in the "New to Java Technology" forum, BTW.
Java derives a lot of its power from the huge library of classes that ships with it, which is called the API. These classes are grouped into packages roughly along functional lines, so you should expect to see some relationship between the classes found in a given package - the java.net.* classes all pertain to networking. The API documentation describes three things about each class - fields that are available, constructors that you can use, and methods that you can call. Basically, anything at all that you can do with a given class (ThreadGroup, for instance) can be found in the documentation for that class. Typically (for non-static classes), you call the constructor that seems most appropriate via the "new" keyword, and, using the reference returned from that, you call the method that does what you want. It's all outlined in the docs.
If you don't get what you need from the docs, then read the appropriate Tutorial (also in the list of links to the left of your screen) find the one on Threads and off you go.
I hope this helped.

SAP CRM multiple clients possible

Hi,
We have a NetWeaver SAP CRM system (ABAP + JAVA) stack.
We run an internet webshop application on the JAVA stack connected to CRM ABAP stack, client 010. The CRM ABAP stack connects to SAP ERP.
Q1: Is it possible to add a new client 020 in the ABAP stack of the CRM system?
Q2: I don't understand in CRM the connection between the JAVA and ABAP stack. If I add a new ABAP client 020, do I need to copy the JAVA stack/client also?
Who can help me guiding in which direction I have to go?
Note: We want to connect a non-SAP system to client 020.
Overview:
ERP ABAP (client 010) --> CRM ABAP (client 010) --> CRM JAVA stack
non-SAP (legacy system) --> CRM ABAP (client 020) --> CRM JAVA stack
Q3: What are the problems (challenges) I can expect?

Hi Rene,
I think it is not supporting multiple clients. Wait for some additional replies.

Ravindra

One Server Multiple Clients

This server code accepts only one client connection at a time. However, I have several lines that are specifically for the server to accept more than one client. What do I need to do in addition for the server to recognize that it can accept more than one client at a time?

Check out the "Supporting Multiple Clients" bit here: http://java.sun.com/docs/books/tutorial/networking/sockets/clientServer.html
Start a Thread for each client. I'd recommend you create a class:
class Client
    Socket socket;
    ObjectOutputStream out;
    ObjectInputStream in;
    ...any other client-specific data you need...
    public void sendMessage(String s) { ...send to this client...; }
   ...any other client-specific methods you need...;
}Create one of those when accept() gets a new connection, then start the thread for that client.
You may want to keep a LinkedList that contains all the Client objects. E.g. if you want to send a message to all clients you'd loop over the LinkedList and send to each in turn. Synchronize the list appropriately. Removing clients from the list when they close down can be interesting :-) so be careful.

Cisco Jabber client to support Multiple e-mail domains

Hi All,
Per the following link, CUCM an IM&Presence starts supporting multiple domains at version 10:
http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/rel_notes/10_0_1/delta/CUCM_BK_C206A718_00_cucm-new-and-changed-1001/CUCM_BK_C206A718_00_cucm-new-and-changed-1001_chapter_010.html#CUCM_RF_I31EA3AB_00
However, we have heard from Cisco that there is NO Jabber client that works with version 10 to support multiple email domains.
This may or not may be true.
Can someone who has connection with BU confirm this? If there is Jabber client that supports multiple email domains, what is the version and when is it going to be available?
Thanks,
Mustafa

How are you dealing with this DA restriction?
Also, what are your comments about the use of Domain Alias vs. Domain with inetdomainbaseDN pointing to my organization? Which one was your choice?

Looking for a client/server that supports multiple protocol and delivery

Hi all, I don't know if this the right place to ask my question,here it goes.
I am looking to develop a client-server that supports multiple protocols such as HTTP, HTTPS etc. I am looking for a framework( i don't know if that is correct or I need some kind of web-service (soap etc)) that would manage connection, security etc. I would like to like to devote most of my time in developing business objects with multiple delivery mechanism such as sending serilized java objects, xml message or soap message, or in some case JMS message as well. So I need a client server that can come in via TCP/IP or HTTP or anyother industry standard protocol and I should be able to service him with pub/sub model and also request/response model as well.
I don't know if I had explained what I need, I would like to know what technologies I should be evaluating and which direction I should be heading... Also the server I'm developing should be free of Java constraints if needed...
Also this service is not webbased service as now but if need arises I should have a flexibilty to make them web enabled in future. Also I would like to work with open source webservers or appservers if I need

"i3 was created because wmii, our favorite window manager at the time, didn't provide some features we wanted (multi-monitor done right, for example), had some bugs, didn't progress since quite some time and wasn't easy to hack at all (source code comments/documentation completely lacking). Still, we think the wmii developers and contributors did a great job. Thank you for inspiring us to create i3. "
To change the border of the current client, you can use bn to use the normal border (including window title), bp to use a 1-pixel border (no window title) and bb to make the client borderless. There is also bt which will toggle the different border styles.
Examples:
bindsym Mod1+t bn
bindsym Mod1+y bp
bindsym Mod1+u bb
or put in your config file
new_window bb

LDAP supporting multiple DNS domains

I have an environment with multiple DNS domains, and am configuring a Directory server (DS 6.3.1) to centralize various OS configuration maps including user authentication. None of the DNS domains have unique data, so I'd like to do something like storing all the real data in one suffix, then somehow have all clients look to that primary suffix. I am aware that the Solaris Native LDAP client wants to bind to a nisDomainObject that matches its DNS domain. I'm just having a hard time believing that I really need to manage all those individual suffixes when they don't have unique data requirements.
Take as an example the following domains to be supported: foo.example.com, bar.example.com, dev.example.com, qa.example.com, prd.example.com (no hosts are actually in "example.com", they are all in subdomains). Again, all share common configuration data, same user IDs, etc - no unique maps are required.
I created a suffix, "dc=example, dc=com", set it up with idsconfig. All is well there.
[A] My first thought is to bind all Solaris clients, regardless of their DNS domain, to the baseDN of "dc=example, dc=com" in order to avoid having a separate suffix for each DNS domain. I tried to do this using "-a defaultSearchPath=dc=example,dc=com" with ldapclient init, but it failed with an error indicating it wants to see the nisDomainObject of its real DNS domain.
The second though I had, which I don't believe is possible, is to find some sort of a LDAP equivalent of a symbolic link so that I could actually have an object for each DNS domain, but it would simply point back to "dc=example,dc=com". I can't find anything in the documentation which suggests this is possible, but I'd love to be wrong!
[C] Perhaps this could be somehow done with a rats nest of SSDs, but that really seems unwieldy, right? I plan on using a fair amount of the available objects, so it would be many SSDs per suffix. Yuck.
Can anyone comment on my above thoughts, or provide how they would go about supporting multiple DNS domains that have common configuration data?
Thank you,
Chris

Ok, I answered my own question. Turns out it's pretty easy. Just use the "-a domainName=example.com" option with `ldapclient` then make sure that the FQDN of the LDAP server is available (or use its IP address). My problem was that the ldapclient overwriting nsswotch.conf was clobbering the SSL session because I used the FQDN which couldn't resolve.
This leaves an interesting condition of having the output of "domainname" not match the DNS domain. I'm testing now to see if this causes any unexpected issues with our environmnet, but I suspect it's not a problem.

Accessing the same stateful session bean from multiple clients in a clustered environment

I am trying to access the same stateful session bean from multiple
          clients. I also want this bean to have failover support so we want to
          deploy it in a cluster. The following description is how we have tried
          to solve this problem, but it does not seem to be working. Any
          insight would be greatly appreciated!
          I have set up a cluster of three servers. I deployed a stateful
          session bean with in memory replication across the cluster. A client
          obtains a reference to an instance of one of these beans to handle a
          request. Subsequent requests will have to use the same bean and could
          come from various clients. So after using the bean the first client
          stores the handle to the bean (actually the replica aware stub) to be
          used by other clients to be able to obtain the bean. When another
          client retrieves the handle gets the replica aware stub and makes a
          call to the bean the request seems to unpredictably go to any of the
          three servers rather than the primary server hosting that bean. If the
          call goes to the primary server everything seems to work fine the
          session data is available and it gets backed up on the secondary
          server. If it happens to go to the secondary server a bean that has
          the correct session data services the request but gives the error
          <Failed to update the secondary copy of a stateful session bean from
          home:ejb20-statefulSession-TraderHome>. Then any subsequent requests
          to the primary server will not reflect changes made on the secondary
          and vice versa. If the request happens to go to the third server that
          is not hosting an instance of that bean then the client receives an
          error that the bean was not available. From my understanding I thought
          the replica aware stub would know which server is the primary host for
          that bean and send the request there.
          Thanks in advance,
          Justin


          If 'allow-concurrent-call' does exactly what you need, then you don't have a problem,
          do you?
          Except of course if you switch ejb containers. Oh well.

Hello All,
we have created shared folder on multiple client machine in domain environment on different 2 OS like-XP,Vista, etc.
from some day's When we facing problem when we are access from host name that shared folder is accessible but same time same computer when we are trying to access the share folder with IP it asking for credentials i have type again and again
correct credential but unable to access that. If i re-share the folder then we are access it but when we are restarted the system then same problem is occurring.
I have checked IP,DNS,Gateway and more each & everything is well.
Pls suggest us.
Pankaj Kumar

Hi,
According to your description, my understanding is that the same shared folder can be accessed by name, but can’t be accessed be IP address and asks for credentials.
Please try to enable the option below on the device which has shared folder:
Besides, check the Advanced Shring settings of shared folder and confrim that if there is any limitation settings.
Best Regards,
Eve Wang

OSB (11.1.1.7): Can OSB/Weblogic (11.1.1.7) support multiple PKIs (Public Key Infra-structure)

Hi All,
Would you be able to help me in understanding if OSB/Weblogic (11.1.1.7) can support multiple private key's in the domain to enable 2-SSL W/S calls ?
Solution walk-through :
A 3rd Party Web Service is only accessible via 2-way SSL http channel. To achieve this, OSB is required to use the private key which is issued by 3rd party. This private key and 3rd party root certificate (CA) need to be installed into OSB’s keystore which is based on Java Keystore format.
The private key (issued by 3rd Party) will be used by OSB for identity signature. This private key is bound to IP address of the OSB machine calling the 3rd Party web service. Also, 3rd Party root certificate (CA) will be used by OSB to verify the identity of 3rd Party web service.
Given the private key is used as the identity of the system and should be guarded closely by the target system, we believe this approach needs to be reviewed and assessed accordingly.
Limitations and drawbacks with the current solution :
1. The private key of OSB system is issued and controlled by an external application vendor.
2. OSB is enforced to use this private key and its signature algorithm for other external parties’ interactions. The current client certificate issued by 3rd Party is X509v3 certificate which uses RSA, with a 2048-bit key size, signed with a SHA-512 hash.
3. The SSL is self-signed, not signed by a publicly trusted cert provider (i.e. VeriSign)
4. Extra dependency on external vendor systems as the key provider. Currently, the keys are bound to server IP address; any changes to the production environment, (i.e. adding new nodes) will require a new key to be generated by 3rd Party system. In case 3rd Party is no more used in the future, the keys can no longer be generated.
Conclusion : OSB does not support multiple PKIs (Public Key Infra-structure) which is a mapping mechanism that OSB uses to provide its certificate for SSL connecitons to the server. Multiple private keys, require multiple PKIs which OSB does not handle.
So, do you agree that OSB/Welblofic (11.1.1.7) could not support multiple private key issued by more than one 3rd party vendor ?
Thanks,
Kunal Singh

Hi Kunal,
Although it is recommended to have 1 key pair for 1 identity store as it represents unique identity of your domain but you can:
import multiple key-pairs in your identity store
Configure PKI credential mapper to use reference of identity store consisting of multiple keys
When in your OSB project, you create Service Key provider(SKP) then it loads all the private keys present in identity store referred by PKI mapper. It will browse both the keys.
Depending on your requirement, you can choose different key pair for for different SKPs for "Client Authentication key" section(For SSL) and "Signature key" for DigiSign.
Please let me know if i understood your query correctly and above helps.

Ankit

JAX-WS: How to choose from multiple client certificates on the fly?

I have a webapp that is calling a web service supplied by a vendor. The vendor requires the use of client certificates for authentication, and I have successfully called their service using the PKCS#12 keystore they gave us with JAX-WS 2.2 using code like this:
    System.setProperty("javax.net.ssl.keyStore", "myKeyStore.p12");<br />
    System.setProperty("javax.net.ssl.keyStoreType", "pkcs12");<br />
    System.setProperty("javax.net.ssl.keyStorePassword", "password");The problem is, my webapp will be supporting multiple business units, and the vendor differentiates between our business units by issuing separate certificates for each. So I'm in a quandary: I have four PKCS#12 files, one per business unit, and my webapp will need to decide which one to use at runtime. Moreover, this webapp could be heavily used by many simultaneous users, and thus more than one of the certs may need to be used at the same time. Hence whatever the solution is, it will need to be thread safe.
I was able to combine all four certificates into a single JKS keystore using the JDK 1.6 "keytool -importkeystore" operation with each of my four PKCS#12 certs, so I now have all four in a single JKS keystore. The above code then becomes this:
    System.setProperty("javax.net.ssl.keyStore", "myKeyStore.jks");<br />
    System.setProperty("javax.net.ssl.keyStoreType", "jks");<br />
    System.setProperty("javax.net.ssl.keyStorePassword", "password");So my challenge now is to programatically select between the four possible certs when calling the vendor's web service. How do I do that with JAX-WS RI 2.2?
Thanks,
Bill

Just to close the loop on this (and for the next person trying to figure out how to do it), I was able to [extend X509KeyManager as described in Alexandre Saudate's blog|http://alesaudate.com/2010/08/09/how-to-dynamically-select-a-certificate-alias-when-invoking-web-services/] . I was then able to set the com.sun.xml.ws.developer.JAXWSProperties.SSL_SOCKET_FACTORY on my JAX-WS request context to use my custom SSLSocketFactory, and it works like a charm!
Thanks,
Bill

Multiple Clients in BW 3.5 Development Systems?

In a Development BW 3.5 environment, can we have multiple clients? For instance, can we have a unit test client(with master and transactional data), a security client, and a golden configuration client.
We have heard that there may be issues with having more than one client, but we are not sure if this is correct. Our BW unit test client would be the only one of the three that is connected to a R/3 (4.7) Development client. The security and golden config client would not be connected to external systems. Is this landscape possible and supported by SAP?

Rick,
You cannot have more than two clients. A client is a technique used for isolating data records and configuration data which is technically stored in the same database tables into mutually exclusive sets of data. Clients may exists as separate for project or organizational reasons. Most configuration data is generally client independent in SAP operational systems while transactional and master data are usually client specific.
SAP BW Application does not make extensive use of the client concept. Infact with SAP BW all specific application functions can take place in one client. SAP BW does utilize basis clients technically but that is only for systems administration purposes.
Hope it helps.
Thanks
Mona

Multiple Clients in SCM-APO?

In a Development SCM-APO 5.0 environment, can we have multiple clients? For instance, can we have a unit test client(with master and transactional data), a security client, and a golden configuration client.
We have heard that there may be issues with having more than one client, but we are not sure if this is correct. Our SCM-APO unit test client would be the only one that is connected to a BW (3.5) Development client and a R/3 (4.7) Development client. The security and golden config client would not be connected to external systems. Is this landscape possible and supported by SAP?

I do not have a good answer but it seems APO-DP uses BW as Data Mart which results in some restriction in using multiple client. See SAP Note 522569 for details. Moreover in the Multi-client Whitepaper (attached to SAP Note 31557) the table in page 23 mentions Multi-client Status for APO with DP : Not OK and APO w/o DP : Restricted OK.
Hope this is of some help.

[SOLVED]Looking for a tiling manager which supports multiple monitors

I use musca and I absolutely have no problems with it other than this :
http://bbs.archlinux.org/viewtopic.php? … 04#p774104
I also tried emailing the musca distribution list but it bounced, so I am not sure how actively it is being maintained.
So I am on the lookout for a new tiling window manager. I know Xmonad supports multiple monitors, but I do not know haskell and I was hoping to find something else as well. Xmonad is also not a manual tiler.
So let me know if anyone of you knows of a tiler that has the above support.
EDIT : I have already looked at the Comparison of Tiling Window Managers over at the wiki. Infact I was the one who added Musca's entry in that table.

"i3 was created because wmii, our favorite window manager at the time, didn't provide some features we wanted (multi-monitor done right, for example), had some bugs, didn't progress since quite some time and wasn't easy to hack at all (source code comments/documentation completely lacking). Still, we think the wmii developers and contributors did a great job. Thank you for inspiring us to create i3. "
To change the border of the current client, you can use bn to use the normal border (including window title), bp to use a 1-pixel border (no window title) and bb to make the client borderless. There is also bt which will toggle the different border styles.
Examples:
bindsym Mod1+t bn
bindsym Mod1+y bp
bindsym Mod1+u bb
or put in your config file
new_window bb

Multiple clients in SAP BI possible to create?

Hi,
I already have a SAP BI system on client 150. Is it possible to create a different client for the same system? In R/3 we do the developement and import it through SCC1. If I want similar scenario in BI then is it possible?
Regards.
Shailesh Naik

Technically, you can have multiple clients. SAP does support it. It has its own limitations though. Refer the below note:
Note 522569 - BW: Working in several clients (especially APO 4.x/SCM 4.x)
But advise is not to do it unless its a testing environment.

Jazz

Support multiple clients.
