DLL's - Websphere MQ and Java Client

I am trying to post a message to Websphere MQ by using JMS Admin and Webspehre Application server. I have configured JMS Admin for registering the JNDI name with app server. I am using a standalone java (makes IIOP call) Application for posting the message. When I am running the java client in the machine where the MQ is installed the application runs fine. But, when I use it in a different machine, It is informing that variour DLLs are absent. Please let me know if all the Websphere MQ dlls need to be placed in the Stand alone java client machine.
Thanks a lot in advance.
Arun

If you are using the JMSAdmin from IBM in the ma88 support pack and getting this error, then check to see if the following .dll files (or .dll files with similar names) are present in your PATH environment variable:
mqjbdf01.dll
mqjbnd04.dll
MQXAi01.dll
The above dlls are required for the MQSeries jar files to make native calls to MQSeries server.
Please check and this should solve your problem.

JAAS and Java client authentication

I'm trying to use JAAS authentication from a Java Swing client against a
WLS 6.1 SP1 server. Using the samples I've successfully managed to
authenticate a client, however a couple of issues have arisen:
- How can I remove the principal association with the current thread when
the user wishes to log out ? The LoginContext.logout implementation in
the samples doesn't appear to be sufficient.
- I'm assuming that the current server authentication called via
weblogic.security.auth.Authenticate.authenticate does not store roles and
group information as Principals within the returned Subject ? Is there
anyway I can access this information so I can modify the UI for the
current user ?
- Should I be able to establish a secure connection by using
t3s://host:secure_port when authenticating through JAAS ? When I tried
this I received, 'java.rmi.ConnectException - unable to get direct or
routed connection to '904601561764...:<ip address>'
Thanks
Darren

Yes Sun provides a Windows LoginModule implementation called com.sun.security.auth.module.NTLoginModulewhich should do Windows logins (I have not tried it on XP)
However, in order to understand how this all works you have to read the JAAS reference guide and tutorial.

Related to Network program using Java Client and C server

I am little bit experience in java technology. I need an urgent help as I have to submit a document related to C server and Java client. But while searching in net i cant get a proper guidance for C server as many errors thrown in sys/socket.h and other new header files. Can any one help me out for giving source code for C Server. so that i can further involve in that document. Please help me out. i am really helpless by the way the C server thrown error. after finishing that C server only i can concentrate on Java client...

Hai Josah,
Thanks for your reply.. I have gone through many sockets server program in C but the real proble is the header file they include like
socket.h and in.h etc.. they also provide these header files but if we compile in turboC they inturn require some other header files. I dont get the full hierarchy of C server program. I found some help in Java programming Archive about C Server and java client. As i am new to C i cant get the full header files for the server.c if i complete taht only i can proceed to java client. If u can redirect me for any good C sites also i can be thankful for u forever..please

Need to communicate c server on linux & java client on windows

Hi!! I am new to socket programing in both C and Java.
From let I downloaded some client server example for c and java and tried that to link !! (I allways learn this way , and I need to do that little urget )
though cient server in linux is working perfectly fine and same for java. But problem is when I tried to communicate C server on linux and java client on windows, I end up with getting some junk characters. Though they are connected successfully.
Here goes code for java client:

hii!! just trying to make it a little more explinatory
1) what I am trying to accomplish by the above code is: - just need to echo/print from the Server , message send by the Client. I know code is not that good but should be able to perform this basic operation( according to me ).You are wrong. I told you that it won't work as long as you are using ObjectOutputStream and ObjectInputStream. You shouldn't write objects.
2) Message sent by the client is "hello world"(hard coded).No, it's not. You are writing a serialized byte array.
3) what I am getting at the client end is "*message recieved: ur*" (before that It shows the Ip of client machine)
It should print "hello world ".See above.
You are having a problem, and I have told you what the problem is.hey I dont know what went wrong but . I posted all this just next to my first post ...before you posted !!
And hard coded byte array includes "hello world"...may be I am not able to explain properly.

Problem running Java client of EJB deployed on WebSphere

Hi,
I am using websphere studio 5.1.2 with fix pack 3. I have a sample Stateless Session Bean (EJB) deployed and running on websphere.
I wrote a small Java client program as below.
import java.util.Hashtable;
import HelloJavaHome;
import HelloJava;
import javax.naming.InitialContext;
import javax.naming.Context;
import javax.ejb.EJBHome;
import javax.ejb.EJBObject;
public class RemoteConn {
public static void main(String[] ar) throws Exception{
String greeting = "";
try{
Hashtable env = new Hashtable();
//env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
//env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.ejs.ns.jndi.CNInitialContextFactory");
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.ws.naming.util.WsnInitCtxFactory");
//env.put(Context.PROVIDER_URL, "corbaloc:iiop:myhost.mycompany.com:2809/NameServiceCellPersistentRoot");
env.put(Context.PROVIDER_URL, "iiop://localhost:2809");
System.out.println("Before creating context ");
InitialContext initContext = new InitialContext(env);
System.out.println("Before looking up HelloJavaHome.");
//Object obj = initContext.lookup("java:comp/env/ejb/HelloJavaHome");
Object obj = initContext.lookup("ejb/HelloJavaHome");
System.out.println("After lookup javahome.");
HelloJavaHome home = (HelloJavaHome) javax.rmi.PortableRemoteObject.narrow(obj, HelloJavaHome.class);
HelloJava remote = home.create();
greeting = remote.getGreeting("John");
catch(Exception e){
e.printStackTrace();
System.out.println("Greeting::"+ greeting);
I did not have any problem if I write and run this client from Websphere studio environment..
However its giving lot of compilation and runtime errors when I tried to run from command line.
I could eliminated compilation errors by setting the below jar files in the classpath.
testclient.jar; (client jar of my EJB)
j2ee.jar;
naming.jar;ras.jar;
wsexception.jar;
bootstrap.jar;
namingclient.jar;
websphere.jar;server.jar;
ejbcontainer.jar;
ecutils.jar;
Now it is throwing runtime error after the statement, "Before looking up HelloJavaHome.", has printed. Here is the stack trace of exception ..
Exception in thread "main" java.lang.NoClassDefFoundError: com.ibm.CORBA.iiop.GlobalORBFactory

Design Problem : How to design/code a java client which is deployed to all the machines in a cluster and make sure that only one of the java client is active

          hi ,
          I have to design a java client (which is basically a JMS message listener)which
          is deplloyed to all the servers in the cluster. But as these are message listeners,
          i want only one of the instance to be active at a time.
          If the server on which the client is active goes down , I want the second server
          to start listening to messages.
          How do i design this ? Also is there a public api for multicasting that we can
          use ?
          Anybody has an idea on how to go about this..
          Thanks
          nisha


Hi Nisha,
          Failover message listeners? Sounds like you want MDBs, which are deployed on all nodes in a
          cluster. If your JMS destination is a queue, then only one MDB will pick up the message. And just
          like any other ejb service, MDBs failover.

Java clients and IUserPrincipal class not working for authentication

I'm developing a Java client which talks to EJBs on the iAS server via
iiop.
I've already developed EJBs, and they work fine. I'm trying to do user
authentication per the examples in the Rich Client section.
Here are the steps I've taken:
1. I've created a class (achp.security.AchpPrincipal) which implements
com.netscape.ejb.client.IUserPrincipal.
2. I've added the class to the initial context via the following line:
env.put("com.netscape.ejb.client.PrincipalClass",
"achp.security.AchpPrincipal");
3. I do a home lookup with the above initial context when the
application starts, create a bean, and then invoke a method on the bean.
When I do the home lookup, according to the manual, my AchpPrincipal
class should be instantiated (which brings up a login window which then
records username and password for future use).
This never happens. The AchpPrincipal class is never instantiated,
although the home lookup occurs successfully and the bean method call is
also performed successfully.
I'm running server on my Win2K desktop, with SP3. And, of course, I've
properly installed the CXS server (as indicated by the fact that I can
communicate with the EJBs at all though the Java client).
Any help would be appreciated.
Thanks,

Error in the Socket Communication between Java Client and VC++ Server

In my application, using Java Client to do socket bi-communication with VC++ Server, which is done by somebody else.
The error is after the application properly running one or two days, the VC++ Server cannot receive the messages passed by java Client, but at Java client, everything is the same, although using CheckError() after every print(), there is no exception thrown.
The JVM is jdk1.3.1, platform is Win2k Server.
The outputstream is PrintWriter().
Please help me to settle down this problem. Thanks in advance.

I 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.

XI 3.0 and external Java client/web service

Hello,
I'm desperately tryin' to get an external system to work together with XI 3.0.
The setup is quite simple:
The external system is nothing but a simple Java program sending SOAP-based requests to a webservice. It is based on AXIS and is running satisfyingly when connecting directly to an appropriate Tomcat/AXIS-based web service, see the following communication.

I made sure the business service in the integration directory is named SOAPRequest and is using SOAP as the communication channel. As the adapter engine I chose the integration server, since it is the only option, although the SOAP adapter framework is installed (according to the SLD) and deactivated any options like header and attachment.
Upon facing the above response I also tried any kind of derivative with inserting the described tag/attribute/element versionMajor, but to no avail.
My questions are:
What do I have to do additionally to get the whole thing running, i.e. configure my external systems in the SLD, providing proxy settings?
Do I have to create web services within the Web AS (which provide some kind of facade to the XI engine using the proxy generation) and connect to these instead of directly addressing the integration engine (I'm using the URL http://<host>:<port>/sap/xi/engine?type=entry, but I also tried http://<host>:<port>/XISOAPAdapter/MessageServlet?channel=:SOAPRequest:SOAPIn, this led to a 404 not found error)?
What settings do I have to provide to see the messages the client is sending, when looking into the runtime workbench it seems as if there are no messages at all - at least from my client?
Hopefully somebody might help me out or least provide some information to get me going.
Thanks in advance.

Hello Oliver,
all information I gathered so far derives from the online help for XI 3.0, to be found under http://help.sap.com/saphelp_nw04/helpdata/en/14/80243b4a66ae0ce10000000a11402f/frameset.htm. There You'll find - in the last quarter of the navigation bar on the left side - sections describing the adapter engine alonside the SOAP adapter.
Additionally I went through almost all postings in this forum.
This alonside the mandatory trial-and-error approach (I did a lot of it up to date) led me to my current status, i.e. so far I haven't found any kind of (simple) tutorial or demo saying "If You want to establish a web service based connection via SOAP between external applications and XI first do this, then that ...", sadly enough :-(.
Hope that helps, any questions are always welcome, I'll try my best to answer them ;-).
Best regards,
Tomaz

WebServices and Java/Weblogic RPC Client

Hi,
I have a simple usability question :
- Where would I want to use a java client that invokes the (WebLogic) Webservice
using RPC/SOAP - especially the static client model?
- Probably the corollary to that would be - why wouldn't I simply invoke the ejb
using the EJB interface invocation?
In both cases, the information required by the developer to write the code is
same, the coding effort is same (only the Properties object being passed to obtain
the InitialContext is populated with different values) - and everything is hardcoded
i.e. no dynamic behavior advantage.
I ran some quick and dirty benchmarks and the webService client is slower than
the mundane ejb client to the order of magnitude of 1:4, 1:5. (duh .. xml!)
Two advantages that I can think of are :
- Because of HTTP, firewall/port issues may be circumvented when using WebServices.
- The thin client.jar maybe easier to distribute than weblogic.jar.
Shall deeply appreciate any insight to the utility from a business perspective
(read ~ convincing clients).
Thanks,
Ajay

It took me almost 3 seconds to find this so I can see why you would ask. http://java.sun.com/webservices/tutorial.html

Java client for Adep dataservice fill and syncFill

Iam trying to invoke Adep Data services from a java client, but unable to get any help. I would like to invoke fill and syncFill operations from a java client both for load testing and to develop a separate java mobile client application taht wroks with Adep. I tried the following, but does not work from client:
                DataMessage msg = new DataMessage();
                msg.setTimestamp(System.currentTimeMillis());
                msg.setDestination(destinationId);
                msg.setOperation(DataMessage.FILL_OPERATION);
                MessageBroker.getMessageBroker(null).getService("data-service").serviceMessage(msg);
Can you please point me in the right direction.
Thanks
Vijay

Hi Vijay,
At this time, Java, iOS and HTML5/JS clients do not support Data Management Service (DMS). Only Flex based clients support Data Management. That said:
1. From server side, you can invoke Data Management using the DataServiceTransaction (DST) API to invoke fill etc. methods.See the following section of the LCDS guide for an example: http://help.adobe.com/en_US/LiveCycleDataServicesES/3.1/Developing/WS4 ba8596dc6a25eff5473e3781271fa38d0b-7fff.html
2. You could write a remoting destination that exposes methods that internally use DST to invoke fill etc. methods. And you can invoke this remoting destination from the various clients.

Connecting dll from vb and java

hello
i have made a project that involves connecting visual basic and microsoft projects but as my project involves that i make dll of that and that dll should be used by java to use that connectivity. can any help me out. i am in a fix

You have to write a "wrapper" dll -in C - that calls the VB dll. The wrapper must conform to JNI standards.

Diff between Java,Window and HTML Clients

Hi can any body clear me
what is the difference between
1. JAVA Client
2. Windows Client
3. HTML Client.
regards
mmukesh

The Windows client requires SAPGUI for Windows loaded on the dekstop (400+ MB of disk), but it works most efficiently.
The HTML client requires an ITS and is not as efficient, but need no specialized software on the desktop.
The Java client is almost never used except by Mac and Unix users!
Cheers
try searching SDN for SAPGUI variants for more details

Data transfer between C client and Java server

Hello there
I am working on a project where I have to develop a Client based on C and Server based on Java. The client can connect to Java server and it then sends a integer/string to Java server. But.. Java server unable to receive that and throws an IOException.
I use write method to send the integer buffer to the socket.
int out_buffer = 0;
int *pbuf;
pbuf = &out_buffer;
     if (write(acskfd, pbuf, 4)< 0){
               syslog(LOG_ERR,"Write failed. %s(%d)", strerror(errno), errno);
               printf("\tCLIENT:\tWrite failed\n");
               exit(1);
In Java, i use DatainputStream and readnInt method to read the integer from the stream.
cl_sock = socket_out.accept();
DataInputStream sInput =new DataInputStream(cl_sock.getInputStream()) ;
int cmd = sInput.readInt();
Am I missing someting.. Any suggestions would be really really helpful.
Thanks
Ithaca
PS: I running both programs in the same machine.
In C part, I also use host to network byte order conversion (serv_addr.sin_port = htons(portno).

I would suggest writing a Java client to perform the same tasks as the C client.
Then if the Java client does, or does not work this can help dteremine which end is at fault.
Are you flushing your data from the client?

Socket Communication between java client and c++ server

HI,
In my project,I want to do the following:
1.Sending datas from client to server.
2.Getting the response from server to client.
I written the client in java.but the server is in c++.
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?
thanks a lot

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
