Socket communication using objects or xml

I have a client server application that communicates through xml. Each time the clients send the request as a xml and the server parses the xml and responds back to the client as an xml.The client in turn parses the xml and acts accordingly
if i were to use objects to communucate through sockets will there be a significant reduction in system overhead of both the client and the server.?
If not what would be a better implementation of this communication so to resuce the system overhead.

Object Oriented XML Instances - existing standard?

Hi All
I am in search for a standard/package that can remove
redundancy and reduce inconsistencies in XML. It ought
to be done by using object oriented XML instances. I do
not mean XML schema languages like SOX. The
concept I refer to is used earlier on in the config-file. I
have implemented a simple version but as soon as I
realized its potential I also realized that there has to be
an existing standard out there. I have searched the web
without any luck, but since I am new to XML there is a big
chance that I have missed it. I would be grateful if anyone
could point me in the right direction.
To clarify I have an example. Its a small part from the
config-file used by my database bridge and this part is
used to define fields and tables. Following two attributes
are reserved
1. did - the identity of this instance. The name space for
this definition is restricted to the tag name, but can be
seen from anywhere in the project.
2. eid - the identity of the instance that this instance extends.
<database did="my database">
<field_definitions>
    <field did="super" key="no" unique="no" visible="yes" allow_null="no"/>
    <field did="boolean" eid="super" class="ops.dbb.FieldBoolean"
           default="false"/>
    <field did="integer" eid="super" class="ops.dbb.FieldInteger"
           default="0" display_size="10"/>
    <field did="auto_inc" eid="integer" class="ops.dbb.FieldAutoInc"
        key="yes" unique="yes" name="id" visible="no"/>
    <field did="string" eid="super" class="ops.dbb.FieldString"/>
    <field did="string_10" eid="string" size="10"/>
    <field did="note" eid="string" size="50" name="note" allow_null="yes"/>
</field_definitions>
<tables>
    <table did="users">
      <field eid="auto_inc"/>
      <field did="username" eid="string_10"/>
      <field did="password" eid="string_10" visible="no"/>
      <field eid="note"/>
    </table>
    <table did="admin_users" eid="users">
      <field did="security_level" eid="integer"/>
    </table>
</tables>
</database>If there are only a few tables this might not be
justified, but used in a project with hundreds of
tables, this will help considerable.
As fun as it is to reinvent the wheel, I am trying
not to.

Either there are functions in JAXB that I am missing
or you are misunderstanding me jmwollny. I understand
that given a valid XSD schema JAXB will generate
interfaces and classes that I can work with instead of
working with XML files directly. This is really cool,
but it is not the concept I am looking for. When I
write 'Object Oriented XML Instances' I do not
referring to Java, I mean that the XML elements in the
config-file are capable of inheritance, creating
interfaces, creating abstract elements and more. Here
is a smaller example.
<field did="super" key="no" unique="no"/>
<field did="integer" eid="super" unique="yes"/>If we take a look at the second field where
did="integer", it is inheriting the attribute key="no"
from the field where did="super" since the attribute
eid="super" exists. We can also see that since
polymorphism is supported, unique="yes" in the second
field is replacing unique="no" in the first field.
The reason why I think this is helpful is because it
will reduce redundancy and inconsistencies in the
config-file.

Use of synchronized queue for java socket communications

Hi all,
We have a need for a server socket application (stand alone java application) to process just one command per time coming from a java socket client (JSP Web application). There are a lot of users accessing the java socket client, but the server socket can only handle one command per time, so there is a need of a queue type, so users will have to wait for their time.
We've been told that we can use "synchronized Queue", but we don't know what it is and how to use. A URL, book etc. with sample code would assist us, since we are new to both java socket communication and queue of commands.
Can anyone assist us
cheers
Trajano
P.S.
The server socket java application has two threads:
1st thread handles the java socket communication;
2nd thread is a RS-232 serial driver that communicates to several micro-controllers connected on a multi-drop.
JSP web app client socket users can issue various commands at the same time to the java server socket app, however the server can only service one command per time (just one RS-232 COM1 serial port available). The commands have to somehow be added to a queue for processing.

I do not have the experience to offer advice. But I just happened to be reading today about Collections.synchronizedList.
import java.util.List;
import java.util.LinkedList;
import java.util.Collections;
public class Queue {
   private List queue;
   public Queue() {
      queue = Collections.synchronizedList(new LinkedList());
   public Object removeItem() throws InterruptedException {
      synchronized (queue) {
         while (queue.isEmpty())
            queue.wait();
         return queue.remove(0);
   public void addItem(Object item) {
      synchronized (queue) {
         queue.add(item);
         queue.notifyAll();
class Test {
   public static void main(String[] args) {
      final Queue queue = new Queue();
      //start a thread to process items from the queue
      Runnable work = new Runnable() {
         public void run() {
            try {
               Object item = queue.removeItem();
               //do something with item
            } catch (InterruptedException e) {
               //handle this
      Thread worker = new Thread(work);
      worker.start();

Hello .
we are also in process of implementing the same

1)is it a separate add on with ALE to saphr
or using ECC ??
2)can u share the configuration part ??
we are trying it on webas as addon 3.0 .

}OK, My questions are:
[1]. what I generated XML by XSTream is very complicated, especially for object LocationTest, Can we make it as simple as others such as Person object??
[2]. after I run it, LocationTest will popup and a red ball in a panel will dsiplay, after I change red ball's position, I hope to persist it to xml, then when I read it back, I hope to get same picture, ie, red ball stiil in old position, How to do that??
Thanks a lot!!

Positive feedback? Then please take this in a positive way: if you want to work on persisting Java objects into XML, then GUI programming is irrelevant to that goal. The 1,000 lines of code you posted there appeared to me to have a whole lot of GUI code in it. You should produce a smaller (much smaller) example of what you want to do. Calling the working code from your GUI program should come later.

Client / Server Socket Communication - Should use 2 ports?

If we have a client server architecture using a socket based connection, should there be 2 serperate sockets? One dedicated to sending and one dedictated to receiving? What happens if both the client and server both send at the same time? How does that get handled? Does one of the messages get dropped? Thanks...

There are of course reasons you might want to use two sockets.
For instance security. One socket is encrypted and the other isn't. Or because the server initiates a confirmed port connection back it verifies the IP.
Or because the main socket is used for control and the second one is used for data. That way the client can tell the server to pause or make other adjustments in the data while the data is still flowing.

Socket communication failure between Java applet and C++ application

I have a java applet that connects to a C++ application via Java's ServerSocket and Socket objects. THe C++ application is using the Winsock 2 API. The applet and application are running on an NT workstation (SP 6) and using IE (5.5) For a very simple C++ test applications the communictions work fine. Once more code gets added to the C++ application the portion of the socket that C++ listens to seems to close. Upon performing a recv call the return value is a zero. Microsoft insists this is a sign the Java side has shut down the socket. The Java applet can still receive messages from the C++ app but C++ cannot receive responses from the Java side. Java throws no exceptions and an explicit check of the socket shows no errors. Again, what puzzles me is that it works for simple C++ applications. Are there any known conflicts between Java and C++ in this regard?
I have inlcuded the basic java code segments below.

a very simple C++ test applications the communictions work fine. Once more code gets added to the C++ application the portion of the socket that C++ listens to seems to close.
This quite strongly implicates the extra code in the C++ App. The firstly thing I would try would be telnet. Try connecting to both versions of the C++ Application and manually reproducing a proper exchange.
a recv call the return value is a zero. Microsoft insists this is a sign the Java side has shut down the socket.
A correct implementation of recv should return the number of bytes received, or -1 for an error. A zero return indicates no bytes received not a socket closed/error. This sounds like FUD to me.
Are there any known conflicts between Java and C++ in this regard?
I can see no obvious faults, though the code is incomplete, I don't think it's an sockets implementation issue, at either end, it sounds more likely to be a protocol/handshaking bug in the C++ App.

Socket communication via TCP-IP

Hi,
I am new to CF and would like to establish TCP-IP socket
communication with a remote server. How can I exchange XML messages
with a remote server / port via TCP-IP. Do I need to use the event
gateways of does CF offer another way of setting up socket
communication ?
Many thanks in advance !
John

Do I need to use the event gateways of does CF offer another way
of setting up socket communication ?
I would say, yes, use the socket gateway that ships with
Coldfusion. However, it has a functionality I cannot really
understand. If you are a client setting up a socket to connect to
the gateway, the gateway expects your code to have, beforehand, a
value for the variable
originatorID. Yet,
originatorID is a large, unique integer that the gateway
code generates when you connect. That seems to me to be a
chicken-and-egg dilemma.

[nQSError: 12002] Socket communication error at call=recv: (Number=10004)

Can any1 plz help...!
I am unable to start presentation services...! I am currently using windows server 2003 service pack 2. I tried configuring scheduler after which I got the message:
"Windows could'nt start Oracle BI Presentation server on local computer. For more information review the system event log. If this is a non-microsft service, contact the service vendor, and refer to service-specific error code -1."
I am getting these 2 errors:
In nqserver.log shows below error
[nQSError: 12002] Socket communication error at call=recv: (Number=10004) A blocking operation was interrupted by a call to WSACancelBlockingCall.
In nqscheduler.log shows below error
[nQSError: 12002] Socket communication error at call=: (Number=10048) Only one usage of each socket address (protocol/network address/port) is normally permitted.
I have changed scheduler port (in Job manager-->file-->configure options..>schedule-->general tab) to an available open port since 9705 is not available. I also updated port number in instanceconfig.xml file.
Any suggestions would be really appreciated.

have you seen the blog of John about this? http://obiee101.blogspot.com/2008/08/obiee-configuring-configuring-scheduler.html
hope this heps

I wonder whether people who deal primarily with BI Server might be able to help you better than people who deal primarily with the database?

How do I add a variable into an object as xml

I have a xml document with 2 protection order numbers. I want to get the information for one of them which is **protectionOrderNumber="1400042"**. I would like to add strPoNumber variable to the object objXmlCaseDoc. Inside this object is the xml
that was read and put inside the object. I want at the beginning of the xml code inside the objXmlCaseDoc to add the protectionOrderNumber at the end of the first line. This should be added at the beginning of the xml document. In my object (objXmlCaseDoc)
there is no variable strPoNumber. This is why I want to add it at the top. The object has xml document in it.
It should look like this:
<Integration xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:tsg="http://tsgweb.com" xmlns:IXML="http://tsgweb.com" xmlns:CMCodeQueryHelper="urn:CMCodeQueryHelper" protectionOrderNumber="1400042">
My vb code: I have the variable strPoNumber and the object where the xml document is. Object name is objXmlCaseDoc
I want to add the line of code where I have comment Tranform case information into the output format near the bottom of the code.

Socket communication very slow on Mac OS X 10.6

Hi everybody,
I'm using a socket based communication in an application and in Mac OS 10.5 everything works quick and flawless using XCode 3.1.4.
In Mac OS 10. 6, using XCode 3.2.4, I set the Mac OS X 10.6 SDK, I recompiled the app. but the responsiveness of the app is terrible slow. The GUI itself runs OK but any socket related action is painfully slow (sometimes connection timeout).
The socket communication is implemented using standard CFSocket classes.
Is this a XCode migration issue from 3.1 to 3.2 or a Mac OS 10.6 related one (I've seen lots of complains on networking issues)?
Thank you very much,
Dan

Thank you very much for the info but why it worked (and really fast) on 10.5. I also wonder why I didn't run into TCP_NODELAY problem there ? My TCP buffer size is 1K and I'm using the same testing environment.
Of course there is much more to it than some init parameters but still, what could be so different on 10.6 ? And I tried already the sysctl.conf TCP_NODELAY setting but no effect.
This is the code (briefly):
1. CONNECT
// Create signature from ip and port
struct sockaddr_in sin; /* TCP/UDP socket address structure. */
self->m_RemoteSocketSignature = (CFSocketSignature*)malloc(sizeof(CFSocketSignature));
self->m_RemoteSocketSignature->protocolFamily = PF_INET; /* IPv4 */
self->m_RemoteSocketSignature->socketType = SOCK_STREAM; /* Stream oriented. */
self->m_RemoteSocketSignature->protocol = IPPROTO_TCP; /* TCP */
memset( &sin, 0, sizeof( sin ) );
sin.sin_len= sizeof( sin );
sin.sin_family = AF_INET; /* Address is IPv4. Use PF_xxx for protocol
description, AF_xxx for address description. */
/* sin.port and sin.addr are in network( big endian ) byte order. */
sin.sin_port = CFSwapInt16HostToBig( port );
inet_aton( [address UTF8String], &sin.sin_addr ); /* inet_aton() gives back
network order addresses from strings. */
self->m_RemoteSocketSignature->address = CFDataCreate( NULL, (UInt8 *)&sin, sizeof( sin ) );
// Connect the Write & the Read streams to the socket
CFStreamCreatePairWithPeerSocketSignature (
kCFAllocatorDefault,
m_RemoteSocketSignature,
& m_ReadStream,
& m_WriteStream
if((m_ReadStream != NULL) && (m_WriteStream != NULL))
bOpenWrite = CFWriteStreamOpen (m_WriteStream);
bOpenRead = CFReadStreamOpen (m_ReadStream);
2. RECEIVE
CFIndex iTotalBytesRead = 0;
while (true == CFReadStreamHasBytesAvailable(m_ReadStream))
char buffer[1024];
CFIndex bufferLength = 1024;
CFIndex iBytesRead = CFReadStreamRead (
m_ReadStream,
buffer,
bufferLength
// Error ?
if(iBytesRead < 0)
return iBytesRead;
// EOS ?
if(iBytesRead == 0)
return iTotalBytesRead;
iTotalBytesRead += iBytesRead;
if(string != nil)
[string appendString:[NSString stringWithCString:buffer length:(unsigned)iBytesRead]];
3. SEND
CFIndex iBytesSent = CFWriteStreamWrite (
m_WriteStream,
buffer,
bufferLength
Thanks a lot for your help,
Dan

How do I check if section and subdivision exist inside object's xml?

My function is working but not as I expect it to. The problem is that when Section and Subvision are not found in the object aobjXmlGetStatuteRequestNode xml, I get an error NullReference Exception was unhandled by user code. Object reference not set
to an instance of an object.
For that reason, because the two elements are optional, I would like to check if they exist before adding their value into the xml inside the object objXmlRequestMessageDoc.
The if statement I used in my function did not work. When it found Section element, it did not check for Subdivision.
How do I check for both and add them if they exist. If they do not exist, I do not need to do anything and should not throw an error since they are optional.
Object aobjXmlGetStatuteRequestNode has this xml

The following output in the objXmlRequestMessageDoc object is correct but this does not work when Section and or Subdivision are not found in the object aobjXmlGetStatuteRequestNode.
<ns:BasicSearchQueryRequest xmlns:ns="http://crimnet.state.mn.us/mnjustice/statute/service/4.0">
<ns1:BasicSearchCriteria xmlns:ns1="http://crimnet.state.mn.us/mnjustice/statute/messages/4.0">

I have resolved this issue by using two if statements as follows
'check if there is a section and or subdivision if it is there then set the value
If Not (aobjXmlGetStatuteRequestNode.SelectSingleNode("ss:Statute/ss:Section", aobjXMLNameSpaceManager) Is Nothing) Then
objXmlRequestMessageDoc.DocumentElement.SelectSingleNode("ns1:BasicSearchCriteria/st:Section", aobjXMLNameSpaceManager).InnerText = aobjXmlGetStatuteRequestNode.SelectSingleNode("ss:Statute/ss:Section", aobjXMLNameSpaceManager).InnerText
End If
If Not (aobjXmlGetStatuteRequestNode.SelectSingleNode("ss:Statute/ss:Subdivision", aobjXMLNameSpaceManager) Is Nothing) Then
objXmlRequestMessageDoc.DocumentElement.SelectSingleNode("ns1:BasicSearchCriteria/st:Subdivision", aobjXMLNameSpaceManager).InnerText = aobjXmlGetStatuteRequestNode.SelectSingleNode("ss:Statute/ss:Subdivision", aobjXMLNameSpaceManager).InnerText
End If

How to embed jnlp file into html page using object tag

hi everyone,
i have written one jnlp file like this.
<?xml version="1.0" encoding="utf-8" ?>

<jnlp spec="1.0+" codebase="http://localhost:9080/base/" href="SampleExample.jnlp">
     <information>
          <title>Demo Application</title>
          <vendor> </vendor>
          <description>Sample Demo Application</description>
          <offline-allowed/>
     </information>
     <security/>
     <resources>
          <j2se version="1.3+" />
          <jar href="common.jar" main="true" download="eager" />
          <jar href="classes12.jar" download="eager" />
          <jar href="toplink.jar" download="eager"/>
          <package name="com.applet.*" part="applet" recursive="true"/>
     </resources>
     <applet-desc name="grid" main-class="com.applet.PriceGrid" width="1000" height="300"/>
</jnlp>
i am trying embed that jnlp file using object tag like
<OBJECT
classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" WIDTH="1000" HEIGHT="300" NAME="grid">
<PARAM NAME="jnlp" VALUE="http://localhost:9080/base/SampleExample.jnlp">
</OBJECT>
but i am not able to load the applet using Web Start.
Can anyone please help me. This is very Urgent for me.
Thanks & Regards,
Shiva.

thanks.
i am giving my problem clearly. i have one applet. Previously i am loading the applet in my html page using object tag like this...
<OBJECT
classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" WIDTH="1000" HEIGHT="300" NAME="grid">
<PARAM NAME="CODE" VALUE="com.adp.base.applet.PriceGrid.class" >
     <PARAM NAME="ARCHIVE" VALUE="common.jar,classes12.jar,toplink.jar" >
     <PARAM NAME="NAME" VALUE="grid" >
<PARAM NAME="type" VALUE="application/x-java-applet">
<PARAM NAME= "cache_option" VALUE ="no">
</OBJECT>
now what i need to do is
i need load the applet only first time using web start and when ever the applet code changes in the server i need to reload the applet.
for that i kept all the applet resources in .jnlp file.i want to cache all the resources which are in .jnlp file and applet must be displayed within a web page within a browser.
Webstart always open a new application windows.
I need to run an Applet embedded within a web page within a browser.
Is there a way to still use Webstart?

Java WD and Socket Communication

Hi,
Is it possible to use Java Socket Communication with Java Web Dynpro. Or if not what is the best approach to have a Java Socket program integrated with a Web Dynpro Communication.
Basically, I have an application which provides API for communication via Java Sockets.And this needs to be integrated in our SAP application.
Thanks,
CD

Hi,
You are currently using JCO to "Connect to a Remote System" - JCO will connect to a back-end with the main purpose of "executing BAPI's" in it.
When you move to WebDynpro, you have what SAP calls Adaptive RFC Model - this will create a "Model Entity" in you WD Project that will do the same thing your JCO does.
Assume your JCO now calls "BAPI_GET_FLIGHTS", to return the Flights that are currently available - In your newly create WDP Project, you will manually specify what back-end you wanna use when "Importing" and you will tell also the BAPI name. WDP will generate the class structure that you need in order to execute that function.
JCO is what SAP created to execute BAPI's. JCO can be used by any "Java" like application that needs to connect to the back-end. But when you move to WDP, you don't need to use this anymore - You will use WDP Models.
Youi will still need your JCO Destinations created in the Application Server, so behind the scenes WDP creates a "layer" so you don't need to code the JCO calls manually.

Daniel
