Client examples beside Java
Can anyone pls send me some link that teach me how to develop client web services.
I already using Java for writing all the services that will be provided for client. Now I want use other languages for write the client side application to invoke the web services so that I can showing that the web services can communication with different languages client application.
Thanks a lot.
Go on MSDN, it's full of examples!

Last year I posted 4 programs that provided a simple client server using both stream sockets and NIO. I decided as an exercise in using Java 5 to port that code and try to use as many of the new features as possible. The following code is very long and does what all the previous example programs did. In replies do not repost the whole of this message.
It provides a simple chat like client and server. The user can request either a stream connection or a NIO connection or provide one of their own.

(DII) Client Example - - missing class error
To jump into DII, I have copied the source for the "Dynamic Invocation Interface (DII) Client Example" into a new class created in netbeans. The api jar for JAX-RPC has been mounted in the environment. The example compiles fine, but upon execute the following error comes up:
javax.xml.rpc.ServiceException: java.lang.ClassNotFoundException: com.sun.xml.rpc.client.ServiceFactoryImpl
at javax.xml.rpc.ServiceFactory.newInstance(ServiceFactory.java:65)
at node.HelloClient.main(HelloClient.java:29)
Do I need to get another api here? Looking into the jax-rpc jar file I can see the javax.xml.rpc.ServiceFactory class, but can not see com.sun.xml.rpc.client.ServiceFactoryImpl .
Could someone point me to an answer? Thanks in advance for the help.The jaxrpc jar that I downloaded was from under the xml downloads (jaxrpc-1_0-fr-api-class.zip). Once extracted this gave me a jar file of jaxrpc-api.jar.
It seems that you might be using a different jar? (jaxrpc-ri.jar)?
Under my downloaded jar file, there is no client belwo the heirarchy of javax/xml/rpc . Where could I find the download for the jar file that you are refrencing?
Thank you for your help.

Can not build the client example of the webservices/rpc-example
Hi!
I have some problems with building the client example of the webservices rpc example.
I followed the instructions of the readme and was able to build the weatherejb,
after I saved the client.jar in %WL_HOME%\samples\examples\webservices\rpc\javaClient
I put the cleint.jar into the classpath of the setExamplesEnv.cmd:
set CLASSPATH=%JAVA_HOME%\lib\tools.jar;%WL_HOME%\lib\weblogic_sp.jar;%WL_HOME%\lib\weblogic.jar;%WL_HOME%\lib\xmlx.jar;%WL_HOME%\samples\eval\cloudscape\lib\cloudscape.jar;%WL_HOME%\samples\examples\webservices\rpc\javaClient\client.jar;%CLIENT_CLASSES%;%SERVER_CLASSES%;%EX_WEBAPP_CLASSES%;C:\bea
but if I now change to
$ cd %WL_HOME%\samples\examples\webservices\rpc\javaClient
and try to build the ear -files by typing:
ant
I get the message:

thanxWell, Remember(you might have done this) u have to run the
setExamplesEnv.cmd after u add the client.jar in the classpath. Also, the
ant command will work only in the window where u ran the setExamplesEnv.cmd.
Thats what i didnt and it works perfect for me.
Hope this helps u.

Hi!
I have some problems with building the client example of the webservicesrpc example.
I followed the instructions of the readme and was able to build theweatherejb,
after I saved the client.jar in%WL_HOME%\samples\examples\webservices\rpc\javaClient
I put the cleint.jar into the classpath of the setExamplesEnv.cmd:
setCLASSPATH=%JAVA_HOME%\lib\tools.jar;%WL_HOME%\lib\weblogic_sp.jar;%WL_HOME%\
lib\weblogic.jar;%WL_HOME%\lib\xmlx.jar;%WL_HOME%\samples\eval\cloudscape\li
b\cloudscape.jar;%WL_HOME%\samples\examples\webservices\rpc\javaClient\clien
t.jar;%CLIENT_CLASSES%;%SERVER_CLASSES%;%EX_WEBAPP_CLASSES%;C:\bea
>
but if I now change to
$ cd %WL_HOME%\samples\examples\webservices\rpc\javaClient
and try to build the ear -files by typing:
ant
I get the message:
C:\bea\samples\examples\webservices\rpc\javaClient>ant

Storing chinese in client odb from java application
Hi all,
first i like to thank Greg Rekounas for his wonderful support and contribution....
This is my server setup.
os-windows 2000 sp4
db-oracle 9ir2 (unicode with AL32UTF8 charset)
lite-oracle10g r2 (with latest patchset)
nls_lang- AMERICAN_AMERICA.AL32UTF8
storing and retriving chinese in oracle 9i database from isql*plus works.
lite configuration.
1. In $OLITE_HOME\mobile_oc4j\j2ee\mobileserver\applications
\mobileserver\setup\common\webtogo\webtogo.ora file edited the JAVA_OPTION
to:
JAVA_OPTION=-Djava.compiler=NONE -Dfile.encoding=UTF8
2. In $OLITE_HOME\mobile_oc4j\j2ee\mobileserver\applications
\mobileserver\setup\dmc\common\win32.inf file, added the following:
a. In the <file> section, added the following:
<item>
<src>/common/win32/olilUTF8.dll</src>
<des>$APP_DIR$\bin\olilUTF8.dll</des>
</item>
b. In the <ini> section, added the following:
<item name='POLITE.INI' section='All Databases'>
<item name="DB_CHAR_ENCODING">UTF8</item>
</item>
<item name='POLITE.INI' section='SYNC'>
<item name="DB_ENCODING">UTF8</item>
</item>
published the application developed in java using packaging wizard.
downloaded the client in the pc with the following config:
windows 2000 (english)
nls - default.
installed chinese language support.
tried to access 9i database from isql*plus and stored & viewed chinese characters sucessfully.
tried to store a chinese character from java application in the client odb -- failed.
values are getting inserted from the application but when i view them back it shows & # 2 6 0 8 5 ; (i have included a space in between all 8 characters.
but when i copy this no and paste in msword it shows 日(chinese character)
i dont know the exact reason for the above scenerio...................
Also please help me on this too.......
why can i store & view chinese characters sucessfully in isql*plus from the client machine while i cannot do the same on client odb from java application even though the lite config are done to support utf8?
is anything i left out?
should i do any codes changes in java?(java application is of verision jdk1.4_13)
Thanks,
Ashok kumar.GSorry for late replay!! in the SharePoint server both the Claim based and Classic mode is enabled in the server, but still I want to get authenticated via Classic mode just like it happens in SharePoint 2007 and 2010, so do i have to use a different
set of classes to do that if yes can you please tell me those ? -
How can I change java.policy at runtim on client machines using java webst?
Hi,
I have to change java.policy to launch my application through webstart to provide one RuntimePermission "permission java.lang.RuntimePermission "getClassLoader";"
Its because of a bug in java bug "_http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4809366_"
So, my problem here is, how can I do this dynamically on each client machine's java.policy.
I have spent time on this and found some alternatives
1. Specifying an Additional Policy File at Runtime by launching application "java -Djava.security.manager -Djava.security.policy=someURL SomeApp"
Please refer more on this "http://docs.oracle.com/javase/6/docs/technotes/guides/security/PolicyFiles.html"
But, here the problem is, how can I do this using webstart (expert.jnlp) file even though I have the "java-vm-args" tag, its not supporting this argument.
Please refer "http://docs.oracle.com/javase/6/docs/technotes/guides/javaws/developersguide/syntax.html#security";
2. Implementing the Policy in code.
But, not sure how to do this..
How can I grant the runtime permission on every user's machine dynamycally?
Here are some background details on this:
I am using java6 and weblogic 10.3.3.
Here is thing that I tried,
My application downloads a few jars to the client machines using java webstart and then it will get the initial context using the t3 protocal. The jars include wlclient.jar and ojdbc6.jar initially.
The problem here I was facing, when I tried request a bean, it is giving me the following exception in the client logs.It is requesting one state less session bean and I checked the server logs as well and the bean has returned the expected values properly.
But here I observed one more thing, before this request, one session bean(state less) has been requested successfully.

The same is working in some other machine which are in different network. So, I have replaced the wlclient.jar with the wlthint3client.jar.
After replacing this jar I was getting the below exception in client logs while requesting a state less session bean.I also checked whether the request is reaching the server (bean) or not, but its not reaching the server.The problem is same at all the machines irrespective of the networks.

I have tried one more thing, I have taken all the required jars to one of the client machines and executed the main class (by setting the required class path) from cmd using java instead of javaws. Surprisingly, its working fine with out any problem using the wlthint3client.jar.
I also tried the same, by placing wlclient.jar using java in the same way(from cmd instead of javaws ), but I was facing the same exception while requesting the second session bean and found the same above exception in client logs.
To resolve this, I come across the java bug that I have given earlier "_http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4809366_".
In that page, I found a work around for this; suggested by bea to add the Runtime permission "permission java.lang.RuntimePermission "getClassLoader";" to the clients java.policy
So, please suggest me a way to resolve this problem.
Please suggest me if you have any other solutions for this problem.
Thanks in advance :)I still think your problem is nothing to do with that ancient non-bug and that you should be looking elsewhere. You might be lucky and find someone here who can say "Ah, I know what that is" but I doubt it because since Oracle took over Sun this site has gone down hill big time.

I can't get the VI Server/Client example to work on my PC
Hi, I was trying to run the VI server and client example but the client could not find the server even when the server was running and both VI's were running on the same computer.
I checked the VI Server configuration and found that the TCP/IP was not checked off - so I enabled TCP/IP. This did not solve the problem.
Your help is appreciated
KeitaAre you running LabVIEW 7.0? The 7.1 version seems to work reliably but the 7.0 version does not to seem to work most of the time. I am having the same problems as you describe. Must be some bug in 7.0, but I have not had time to compare the code. Anyone?

Step by Step instructions importing Client Certificates on Java Engine
Hi All,
I am trying to configure a <b>Receiver</b> SOAP adapter with SSL, does anybody has step-by-step procedure on how to install the client certificates on Java Engine using Visual Administrator? and refer that keystore in SOAP adapter?
PI 7.0 SP 09
UNIX-Sun Soloris.
Thanks,
LaxmanHey Molugu,
you shouldn't have to install the client certificates on KeyStorage Service, for receiver adapters. The server's public certificate is sent just in the SSL handshaking. What you should have is the certificate authorization tree in your Trusted ACs Service (if the issuer of your client's certificate is not already there).
You need to install client certificates in sender adapters, when your client uses authentication through certificate. Then you need to install that authentication certificate for the authorized users.
Check the following link for SSL on J2EE: http://help.sap.com/saphelp_nw2004s/helpdata/en/f1/2de3be0382df45a398d3f9fb86a36a/frameset.htm

Out of the box, the app-client is trying to connect to:

The complaint is that:

So which should it be? 'service/MyHelloServiceRef' or 'hello/HelloService'
And which source and config files need to be modified.
Also notice that i don't have any client stub files in my build\classes directory. That seems a bit odd. Do I need to gen-stubs as part of the build process?
-DavidHi David,
Not sure if you are still facing the issue .
Just wanted to point out a couple of things which might becausing your app-client demo to fail .
1. The remote webservice application which this client is trying to consume , the helloservice,application is not deployed .
2. The packaged application-client.xml is fine , this is a special demo showing how you can invoke a webservice if you are interested in doing only certain things and not others .Look inside the client code of this demo and compare it with client of say the web-client/ demo .The different invocation styles .
3. The 'result.wsdl' that you see is just a copy of the remote ws's wsdl , that gets saved as a result of the ant tasks which checks to see if the remote ws is up .
4. Do an ant clean and run the tests again and let us know if the error's persists in your environment . -
Finding an EJB object. Web clients vs. Java clients
From what I've read this is the process for a web client to find an EJB object: the client uses JDNI to find a reference to the EJBHome interface and then it uses the create method from this interface which makes the container to begin to work, creating an instance of the implementation class and an instance of the EJBObject interface, and returning a reference to the EJBObject, which will be used by the client to call the methods.
Are there any differences if the client is a java application and not a web client?The Java Client talk to the server with random ports
not 80. Gives me a headache. _*why?
There's no need to get headaches about it, in fact no need to worry about it at all.
Just have the JNDI services available so you can do the lookup (which might require opening a port (or more than one) on the firewall, but that's it.
And that's no different between a standalone client and a web application client. Both need to do that JNDI lookup. -
Calling SAP GUI Client from a Java Webdynpro app.
Hello experts,
We would like to call the SAP GUI client from a java WebDynpro application running without portal or ITS. Can it be done by having a web link, with mime registration in internet explorer to kick off the SAP GUI ? (similar behavior with a SAP favorite link saved on the desktop).
many Thanks.Hi,
Webdynpro possibilities:
1. You can try to use LinkToUrl.
with reference to file://<exefile> or your weblink with the mime type (possibly some java coding can be required; I can try to help).
2. other option is to use IFrame and you can use either href to your exe or weblink
Web Explorers:
1. IE: It should work. if you point to exe file popup window will be displayed asking for action (run, save, cance).
2. Firefox: the only way I know to make it work is to modify nsHelperAppDlg.js file (if you need Firefox I can tell you how to modify the file).
Kind Regards, Jack -

Need a Telnet Client Implementation in Java
Hi,
I am looking for a Telnet Client Class in Java.
Any pointers on this is appreciated.

ECM java client - example code
Hi,
Enviroment: ECM 11.x
I need to write ADF application integrated wit ECM. Is there any public java codes with examples ? I mean somethink like examples for SOA Suite http://java.net/projects/oraclesoasuite11g/pages/Home covers e.g. example how to write custom worklist. My requairement is to write some functionality from ECM console, so it would be useful to have some java api usage examples.
KubaActually, what workflows you intend to use? And, what's your use case what-so-ever?
I hope I won't confuse you, but in fact, you could mean three things:
- use UCM native (iDocScript workflows)
- use BPEL workflows
- use BPM workflows (as BPM Suite is now also part of the license)
The last is completely driven from the BPM side, so there you don't need to do anything.
The second works like this: you may define a criteria workflow which passes the item to a BPEL workflow. When BPEL finishes, it passes the workflow back to release the item. If you have samples for SOA Suite, you could reuse them.
Only for UCM native workflows, you would need to write your own codes (calling services - most likely WS), but havinf the first two options, is it worth? -
Cannot acess file on server from client machine using java web start
Hi everyone,
I am creating an appication using JWS and Apache Web Server version 2.0.54 on Linux. I am trying to access a file on the server that IS NOT inside the jar file. I have given full access (r, w, x) to all users on my server. We also created a FilePermission object and gave the file read and write access as well. But when we deploy the program and try to get this file, a SecurityException is thrown with the following mesage:
acess denied (java.io.FilePermission filename read) where filename is the file in our local filesystem. Any suggestions on what I can do?
Any help would be greatly appreciated.
Thanks,
RajIt sounds like you are trying to access the file as if your JNLP application were running on the server. The JNLP app is running on the client machine, so you will need to use a URL to open the file. Take a look at the JavaDocs for the following:
java.net.URL
java.net.URI
java.net.File
You also need to be sure your server is configured to serve the file. For example, you ought to be able to access the file through your browser using something like http://www.myco.com/myapp/myfile.txt. (How you configure your server is a topic for a different forum.)
You probably also want to look into JavaWS security, and even Java security in general to determine if you need to sign your app or not. Here are some links to get you started:
