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?
Best Regards
Having same issue. Nothing helped so far... Using NWDS 7.0 SP18.
I have turned SDM tracing on and this is what I see on client side after sending first data package:

My connection on server is still active so I have to restart SDM server to reset and try it again.
Anyone have idea whats happening?

Help-how can i connect between a client and servlets on different machines
hi all
I asked this question already but:
I am tring to run a client which is an HTML file that has a "submit" button, that when pressed it should connect (or something) to a servlet, which is on a different mechine.
what must i write instead of: "localhost"?
and what web server should i use?
this is the code on the client side:
<form action=http://localhost:8080/servlet/MyServlet method=POST target=_blank>
<input type=submit name="M1" >
</form>
thank youthanks
I tryed that by writing the ip address of the servlets mechine instead of "localhost", but there was no reaction
i wrote:
<form action=http://10.33.24.33:8080/servlet/MyServlet
method=POST >
<input type=submit>
</form>
what is wrong with that?
when i pressed the submit button nothing happened.
does any body know what can i do? -
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. -
Connectivity between Oracle database and client...
Hi guys,
I was asked to make a connection between oracle client and database via internet so that our clients can access the database from different parts of the country, and the data that is transmitted in the internet does not require security consideration. And I have successfully implemented this.
But later onwards they asked me to structure it in such a way so that clients must be able to select, insert, update and delete data offline, in case there is online connectivity problem.
So my question is, are there any possibilities in oracle to temporarily store data that are available in the oracle database to the client side and then later onwards transfer those datas once the clients are available online. Or are there any other alternative ways...
Additional Information - Client access the database through an application created by VB.
Please do help me on this project.
Thanks in advance for your help.

Asif.You probably should do a cost/risk analysis. Where you are headed might be able to be done (but it will require that the "clients" also have their own copy of the database) but it won't be easy and it certainly won't be cheap, either in initial implementation or in on-going maintenance. The alternative is to take a hard look at your network connections and see if it wouldn't be cheaper/easier to be able to ensure that it is reliable. Remember "the internet" won't break, it is highly redundant. If you have connectivity issues, they will almost certainly be in your own equipment and configurations, so your (your organization) will have the ability to address and fix any issues there. -
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

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:

How to set up internet connection between MacBook Pro and an old eMac?
I got an old eMac without wifi and a MacBook Pro. I'd like to share the network connection via ethernet cable to my eMac, but I can't get it work.
I'd like to use it with screenrecycler and it needs a network connection.
How to do it? How to set up the connection between the client and the host? Could somebedy give me a step by step guide?
Thank you very muchHello,
First, are you using Wifi for Internet on the MBP?
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list, Wifi on the MBP.
In Shating on both, enable File Sharing, Screen Sharing, & Web Sharing on both.
Then with the Ethernet cable between the two, find the IPs of both, or use Finder>Go>Connect to Server>Browse... see what shows up. -
XML over HTTP between client and server
We are trying to pass XML between a client and servlet over HTTP.
We used the code from the StockClient/StockServlet examples as a
starting point but cannot get it to work. Basically we
have a simple command line java client that is trying to access
a VERY simple servlet. When the client tries to write data into
the output stream associated with the connection I get:
"Connection rejected: 'Login timed out after: '15000' ms....."
I have read several postings that instruct me to raise the
timeout limit, but as you can see, I surely don't need 15 seconds
to write this data out! Is there something special I need to do?
Does this have anything to do with known issue #10065
(http://www.weblogic.com/docs51/release_notes/rn_knownprob51.html)
I have followed all of the instructions in the example code
(http://www.weblogic.com/docs51/classdocs/xml.html)...
Any assistance is appreciated...
here is the client code:
import java.io.*;
import java.net.*;
public class TestClient
public static void main(String aa[])
URL url = null;
HttpURLConnection urlc = null;
PrintWriter pw = null;
file://Commented lines indicate other things I have tried
try
url = new URL("http://localhost:7001/ParserServlet");
file://urlc = url.openConnection();
urlc = (HttpURLConnection)url.openConnection();
file://urlc.setRequestProperty("Content-Type", "text/xml");
urlc.setDoOutput(true);
urlc.setDoInput(true);
file://urlc.connect();
pw = new PrintWriter(new OutputStreamWriter
(urlc.getOutputStream()), true);
pw.println("<?xml version='1.0'?><test>testing123</test>");
pw.flush();
file://urlc.disconnect();
} catch(IOException ex) {
System.out.println(ex.getMessage());
Here is the servlet code:

ServletException
super.init(config);

System.out.println("Inside doPost()");

HttpServletResponse resp)
throws ServletException,
java.io.IOException
System.out.println("Inside doGet()");
Jon,
One thing is missed in your client code. When you use HTTP POST to send request,
you have two ways to tell the Web server when to stop reading from your input and
to start process your input: the first one is using "Content-Lenght" header property
to specify how many bytes you want to send to your servlet, the seocnd is use "Transfer-Code:
Chunked" and is much more complicated. I didn't see you pass "Content-Length" in
your client code, in which case, the Web server (Weblogic) cannot know the end of
your request data and could keep waiting for last byte to come out or waiting for
the socket time out (that is what you get).
Since you use servlet, not JSP, I would recommend to code in this way (it works fine
for me, no guranttee for your situation):
Client code: Use a big temprary string, or StringBuffer, or StringWriter to store
all the request data (your xml file content) before you send out the request. After
you finish to form your XML string, calculate the number of bytes (should equal to
the length of the string) and add the request header as
urlc.setRequestProperty("Content-Length", bytes_length);
I will not suggest you using PrintWriter. Think use BufferedOutputStream constructed
from URLConnection and write the bytes (use String.getBytes()) to the servlet and
then flush.
Servlet code: in the doPost() of your servlet, try to find the request data length
by calling request.getContentLength(), then open the InputStream (think to use BufferedInputStream
for performance). Read the contents from the InputStream byte by byte and counter
the number of bytes. Once you get the number of bytes as specified via request Content-Length,
break your reading loop and start whatever you want.
Hope it helps.

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 -
Connection between SMD Agent and SMD server via SAProuter
In our scenario, we have to setup the connection between SMD agent and SMD server(solution manager server) via saprouter. But during the installation of SMD agent, we can only specify the hostname of the managing system, we have no place to add saprouter string(/H/..../H/). I I am not sure if we could connect the agent and server via saprouter, if so how to do it?
Hope someone can give us your precious advices on this issue.
KarlPerfect; and thanks for your response. I found this help page for developers to implement P4 support over SAP router: http://help.sap.com/saphelp_nw73/helpdata/en/48/2992d7ad8758d7e10000000a421937/content.htm
But in the SM Diagnostics Setup options I can set up only a direct HTTP adresses and have no options to set up connections over a sap router to P4 ports directly. I can at the moment only solve my problems with NAT or firewall rules.
And also the diagnostic agent setup has no options to config a proxy or sap router. I found yesterday a blog on sdn side with screenshots of the setup with all available connection opetions to SLD... sry I can not post this link today.
This is an official statment of SAP from the current version of SMD guide; it is also possible but why not from the beginning???:
In some network conficurations, the Diagnostics agent has to connect to the Managing system though a SAP router.
This feature will be fully supported in Solution Manager 7 Ehp2 (7.02).
In order to enable this feature in Ehp1, please contact the Diagnostics Agent support team to get information on how to
setup the agent and on which patch level you can perform the installation.
This thread were a long time not answared; proxy and routing connections are mostly stepmotherly handled by SAP; this is also a problem by set up of automatic RFC generations in SMSY; why there are in the setup assitents no options to set up the router string.
I have absolutly no comprehension for this in year 2011. All this technics are good known and long time tested.
In this case the f**k has provoked an answare to this thread and this is what I expected; but sorry for my style You are right I could also writh why the heck

Socket Communication between java client and c++ server
HI,
In my project,I want to do the following:

Is it possible to communicate with the server using java codings itself?
Im able to send the data from my java client to the server.
but unable to get back the datas from server to client.
Can anyone tell me how to do this?

Error 2032 in communication between Flex Client and WCF
Hi All,
I'm trying to establish communication between Flex Client
and WCF service.
WCF service accepts gZip compressed data and returns gZip
compressed results.
So I used Flex ByteArray.compress() and
ByteArray.uncompress() for this purpose. However, it throws error
2032.
The gZip compression/decompression uses MemoryStream class in
C#. Based on my previous experience, memory stream communication
between Flex and C# gives erro 2032.
Is there a work around for this?
Thanks,
VishalI read some thread in the forum, and found somebody had the similar problem with me. Just want to know how to settle this problem.
In the client/server program. Client is a JAVA program and Server a
VC++ program. The connection works, and the problem appears after some time. The Client sends a lots of requests to Serverm, the server seems receive nothing. But at the same time, the server is able to send messages to Client. The Client also can get the messages and handle them. Don't understand why there this problem and why it appears when it wants.
The client is a Win2k platorm with JDK1.3.1 and the server is also a Win2K platform with VC++ 6.0.
In the Client, using:
inputFromServer = new BufferedReader(new InputStreamReader(socket.getInputStream()));
outputToServer = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())),true);
Hope can get your help. -

Proxies: are interfaces which will get executed in the application system.They can be created only in the system from message interfaces using the proxy generation functions.
The biggest advantage of the proxy is that it always by passes the Adapter Engine and will directly interact with the application system and Integration engine - so it will and should give us a better performance.
The literal definition of a proxy is an object / process authorized to act for another; an agent or a substitute. In simpler terms, proxies in the XI context are objects used to encapsulate the creation (from a sender system) or parsing of XML (at a receiver system) as well as the communication with the relevant runtime components required to send or receive those messages. The Proxy Runtime controls these objects / processes, and can itself be controlled by the applications it communicates with.
The Proxy currently has the following components available:
1. ABAP Proxy Communication using XI or Web Services
2. Java Proxy Communication using XI (J2EE)

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.

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.
Regards
Raj
