Location of stubs, skeletons, remote interface ,client and server files
I have a question to the subject mentioned above :
In a training example for RMI I red the following :
.... stubs, remote interface and client files into
client location
... skeletons, remote interfaces, server files and stubs
into server location ....
I understand that with the exception that the stubs must also be located at server side. My understanding is
that it is enough if those reside only at client side. Is that
right or wrong ?
Thanks for your comment.
Regards,
Oskar
The stubs must be available (in the classpath) on the server side. This is because when a remote server object is exported, the RMI runtime creates an instance of the stub (instead of the server) and sends it whenever a reference to the server is encountered. In order to create (and then serialize) the stub, its class file must be available on the server.

Hello. I would like to write async tcp client and server. I wrote this code but a have a problem, when I call the disconnect method on client or stop method on server. I can't identify that the client or the server is no longer connected.
I thought I will get an exception if the client or the server is not available but this is not happening.
private async void Process()
try
while (true)
var data = await this.Receive();
this.NewMessage.SafeInvoke(Encoding.ASCII.GetString(data));

How can I determine that the client or the server is no longer available?

Have you debug these two applications? Does it go into the catch exception block when you close the client or the server?
According to my test, it will throw an exception when the client or the server is closed, just log the exception message in the catch block and then you'll get it:
private async void Process()
try
while (true)
var data = await this.Receive();
this.NewMessage.Invoke(Encoding.ASCII.GetString(data));
catch (Exception exception)
Console.WriteLine(exception.Message);
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
By the way, I don't know what the SafeInvoke method is, it may be an extension method, right? I used Invoke instead to test it.

JSSE Client and server communication problem .err:untrusted server cert
Hai all,
I am trying to communicate JSSE client and server.
I have created root.cert(CA),root.key,server.cert,server.key , client.cert and client.key. All these certificates are created using openssl.
I have placed root.cert in default keystore cacerts.
I have created a keystores(server & client) name mykeystore.
I have placed root.cert and client.cert in the client keystore.
I have placed root.cert and server.cert in the server keystore.
But during the run time i am getting javax.net.ssl.SSLException: untrusted server cert chain.
please suggest the modifications needs to be done to fix the error.
please tell me In the client keystore and in the server keystore....what certificates we need to put?
whether my approach as said above is correct or not?
In java code how to specify this particular certificate we are referring?
I have coded in this way ....
SSLContext ctx;
KeyManagerFactory kmf;
KeyStore ks;
char[] prasad = "prasad".toCharArray();
ctx = SSLContext.getInstance("SSLv3");
kmf = KeyManagerFactory.getInstance("SunX509");
ks = KeyStore.getInstance("jks");
ks.load(new FileInputStream("mykeystore"), prasad);
kmf.init(ks, prasad);
ctx.init(kmf.getKeyManagers(), null, null);
factory = ctx.getSocketFactory();
But my doubt is we are specifying only keystore name with that how it will check root.cert(ca) and client.cert and server.cert?
Is there any modifications need in my code?
Please tell me some way ...
Thanks ,
Prasad.Hi prasad,
There will be a problem with the certificates being received from thr remote server or client. Check that your trust store contains the certificate of the remote machine or the CA that signed it and that the certificate has not expired.
Also be sure that both machines are using the latest version of the JSSE.
Hope this will help you.

Anil.

Communication between two jvm (client and server)
Hi ,
I want to access the UME service of the SAP J2EE Container using a stanalone client application.
So the client would be running on remote JVM.
Here we use the JNDI service to communicate between the client and server.
p.put(Context.INITIAL_CONTEXT_FACTORY,"com.sap.engine.services.jndi.InitialContextFactoryImpl");
p.put(Context.PROVIDER_URL, providerURL.trim());
p.put(Context.SECURITY_PRINCIPAL, securityPrinciple.trim());
p.put(Context.SECURITY_CREDENTIALS, securityCredentials.trim());
Context ctx = (Context) new InitialContext(p);
Object objRef = ctx.lookup(ejbName.trim());
I want to know that is the communication between the client and server secured in this scenario
Best Regards
ManojOkay, the client and server VMs are different implementations of the Hotspot engine. Hotspot basically takes the Java bytecode from your .class files and turns it into native machine instructions at runtime. (The optimizations are actually much more complex than that, but that's the basic concept.)
The client VM is so named because it's designed to be used for GUI-type applications interacting with the user. It is designed to have a quicker startup and smaller memory footprint.
The server VM uses more memory and is typically slower at starting up than the client VM, but can often perform ridiculously fast. This of course depends completely on the particular code being run, and you should probably profile and see which VM works better for your application.
Some interesting optimizations are performed by the 1.4.1 server VM, such as: removal of array-bounds checks (when it determines that the index can't become out of bounds), inlining of methods, and more.
Here is a link to more info if you're interested:

Connection between SDM client and server is broken
Dear All,
First of all this is what I have
-NW04 SPS 17
-NWDS Version: 7.0.09 Build id: 200608262203
-using VPN connection
-telnet on port 57018 is succesfull
I can login to SDM server (from NWDS and from SDM GUI) I can see the state of SDM(green light), restart it, can navigate through tabs in GUI, but every time I am trying to deploy an ear i have this error:
Deployment exception : Filetransfer failed: Error received from server: Connection between SDM client and server is broken
Inner exception was :
Filetransfer failed: Error received from server: Connection between SDM client and server is broken
I have already read a lot of topics,blogs,notes but didn't find the solution.
Can anybody help me?

Client and Server in one process
Hi all,
I am trying to create a process which can act as both Client and Server.
How can I do this?
Thanks!AH. That's a better definition or explanation. Thanks.
This smells of a single process with multiple threads, each thread handling the basic needs of your requirements. In other words, have a thread deal with making one or more client type connections (use a main thread - the client controller - to spawn client-connection threads. This assumes you need multiplicity in your client-connection model.
Then make another thread - the server controller - to handle inbound connections, spawning a new thread for each inbound connection. Your main thread, the one that contains your main method, can watch everything that's going on and log or report what's going on in your client and server threads.
Going into specifics would be a lot to do here. Maybe someone is up for the challenge. Of course, this being a "New to Java Technology" forum, these concepts may be a bit beyond your skillset.
This is not the only way to go about solving your problem, but it's the only way I can think of at the moment given your requirements.
Hope this helps some. -
Communication between client and server
I am using sockets for communication between the client and the server. is there any other way that i can use for communication between the client and server???
Plenty of ways: JMS, SOAP, RMI, a RESTful API, writing-files-to-a-shared-directory-on-the-disk, Sneakernet, ...
Some of them use sockets (or better TCP/IP) as the underlying protocol.
But to give you a good answer, you would have to tell us why you want a different way. I hope you're not searching for a different way just for the sake of being different. -

Socket communication between client and server
Hi all,
I am doing an assignment for communication between java client and java server using sockets. This communication is in the form of XML documents. I am facing a problem in this communication.
Actually at Server side I'm creating an XML document(Document type object) using DocumentBuilderFactory in javax.xml.parsers package and transforming this Document into a stream using StreamResult.
My code is :
Transformer xmlTransformer = TransformerFactory.newInstance().newTransformer();
StreamResult xmlString = new StreamResult(currentClientHandler.getSocketOutputStream());
DOMSource xmlDocSource = new DOMSource(xmlDocument); // xmlDocument is Document type reference
xmlTransformer.transform(xmlDocSource, xmlString);
so, this xmlString(i.e. StreamResult) is passed directly into the output stream. Here I need to close() output stream after transform() call to help SAX parser to know about end of stream.
Now at Client side, I am parsing this stream using SAX parser. It parses this correctly. But when sending some another data back to Server when client opens output stream, it given Socket closed exception. I know that closing input or output stream closes socket. But in my problem, I have to send data in streams and not by using files or byte[] etc.
So what is nearest solution to problem ??
Plz help me. Any kind of help will be greatly appreciated.hi
thanks for ur reply.
I didnt get any error msg while getting the back the datas.
Actually i divided my application into two parts.
My application will act as both server and client.
server ll get the browser request and send to the client and the client will send that data to the c++ server.
Im able to do that.and unable to get the data from server.
Didnt get any error.
can u tell me how to make an application to act as both client and server.
I think im wrong in that part.
thanks a lot -

s.close();this has nothing to do with your code, but how you are running it. It is a classpath problem.
You should go to the directory where the UDPClient.class is, and type
java -classpath . UDPClient
similarly for the UDPServer -
Abap proxies ( Client and Server proxies)
Hi Team
Good day to you. I am now started doing some example scenarios on ABAP proxies(ie Client and Server proxies). After going through the blogs which are avialable, i am writing this question to you for clarification.
As per my understanding, the below are the required predefined settings which i need to do in my landscape to generate abap proxies(ie client and server proxies).
My landscape includes the below systems.
System A : SAP XI 3.0 system and
System B : SAP R/3 on WAS 620
SAP R/3 predefined Steps
1.Create HTTP connection in the business system.
2.Configuration Business system as local Integration Engine.
3. Connection between Business System and System Landscape Directory.
4. Maintaining the SAP J2EE Connection Parameters for LCRSAPRFC and SAPSLDAPI in SAP J2EE engine
(Here in the step 4, i found the below needs to be done)
1. Goto J2EE Engine
2. Choose Cluster --> Server --> Services. JCo RFC provider
3. Under RFC destination specify the following:
Program ID: LCRSAPRFC
Gateway Host: <Integration Server host>
Gateway Service: <Integration Server gateway service>
Number of process: 3
4. Under Repository specify the following:
5. Choose Set.
Application Server: <Integration Server host>
(i am not able to perform the steps which comes under point 4. so please Guide me how to goto J2EE engine and configure accordingly.
5. Maintain SLD access details in Transaction SLDAPICUST.
As per my understanding, i need to do the above predefined configuration steps in SAP R/3 system (ie bussiness System) for doing Abap Client or Server proxies.
And in the meantime, i would like to know whether i need to do any predefined configuration steps in XI 3.o system also. Please check and suggest me accordingly.
Once i get clarification on predefined configuration steps, i will proceed with the example scenarios on client and server proxies which are already in SDN.
Thanks in advance.
Regards
RajHello Pavan
thanks for your response. you said that for the connection type 'H' we need to provide values for GATEWAY HOST and GATEWAY SERVICE but here i need to create the RFC destination of type 'T'. so please tell me whether i need to give the values for GATEWAY HOST and GATEWAY SERVICE for connection type 'T' also and the second thing is please tell me the difference between Application system and bussiness system accordingly to my landscape which i mentioned in my question.
I am in little confusion because as per the requirement for abap proxies in the blog they mentioned that all these setting should be done in the bussiness system (ie SAP R/3) but you are saying that Application system. so please clarify.
My landscape which i am going to use in Abap proxy generation
System A: XI 3.0
System B: R/3
Here which is bussiness system and which is application system. Pls calrify.
Thanks in advance.

Hai all,
I am trying to communicate jsse client and server.
It is showing socket closed error.
when will we get java.net.SocketException: Socket closed?
please tell me way to sort this problem
Thanks,
Prasad.Hi prasad,
There are two reasons for this error to occur
java.net.SocketException: Socket closed
(i)First is that the provider is not registered properly. Check your java.security files and make sure that you have created an entry for
com.sun.net.ssl.internal.ssl.Provider.
Then make sure that there are no extra java.security files on your hard drive that are being used by your runtime configure your providers. If there make sure to add the providers to them also.
(ii) Secondly there may be problem with your keystore. Make sure that you are providing the proper file and password for your keystore.
If you are using SSL socket server then check the following code:
SSLServerSocketFactory ssf = (SSLServerSocketFactory )SSLServerSocketFactory.getDefault();
ServerSocket ss = ssf.createServerSocket(PORT);
Socket s = ss.accept();
If you are using regular sockets, perform the following:
ServerSocket ss = new ServerSocket(PORT);
Hope this will help you.
