(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.

Missing Class error from handler class - urgent question!

Hi,
I am getting an "Missing Class" error when running a web service. The web service was generated from a Java class via the "create J2EE web service" option.
The web service has a JAX-RPC handler class added, which belongs to the same package as a logging class. The logging class is used to write to a file for debug purposes. A "missing class" error is being generated whenever I attempt to invoke the web service (via the enterprise manager test util), the error refers to the logging class which is used by the main handler class. The JAX-RPC handler works fine by itself, the error is only seen when I attempt to use the logging class.
I have re-built, re-deployed from scratch again, but still get the same error! Am I missing something simple here?
thanks for any advice

Cant you paste some of your code, formatted in code tags? It looks like there is a problem passing some of the XMl response, it doesnt like a tag html.
If you post some code somebody might actually be able to help you.

Oracle AppsAdaptor causing Missing class error

Hi
Can any one help with the error we are encountering below. We have a production process that uses an Oracle Apps adaptor to call one of the supplied Oracle API's to insert data into the fnd_flex_values table from a BPEL process. Originally the adaptor was working but recently it stopped working when inserting records causing the errors below.

Mustafa,
This is just a suggestion. In OC4J stand-alone 10.1.3.0.0, you can still use the "applib" subdirectory. In other words, try removing the shared library you created, as well as any references to it in any of your deployment descriptors or OC4J configuration files and simply place all the required JARs in the "applib" subdirectory. Then undeploy your application completely -- in other words, delete all related files and directories and remove all references to it in the OC4J configuration files -- and deploy it again.
Good Luck,
Avi.

Problems running DII client for consuming webservices

Hello webservices experts,
am running into problems - when I try running my DII client for a webservice that I've successfully deployed on j2sdkee1.4.
The exception goes like this
java.rmi.RemoteException: JAXRPC.JAXRPCSERVLET.28: Missing port information
at com.sun.xml.rpc.client.dii.BasicCall.invoke(BasicCall.java:462)
I've searched this forum and others as well. Although a lot of people seem to be having this problem nobody seems to have got it solved. Any way out? The client is a mere copy paste of the DII client example in j2eetutorial 1.4

Solved it ! Some endpoint alias problem during deployment ! Now works fine !

Hi,
actually you increment the index
pstmt.setString(++idx,inrecord.getCommentID());
which means you never have an index of 0 but always start with 1

Composite invoking Spring Context errors with Missing class indicator field

Hi. I’m working on a composite with a Spring Context component that is referenced in a BPMN process and have run into some issues and I was hoping you may have some insight.

Using Studio to develop DII Client for DiningGuide example

Hi,
I am trying to develop a DII client to the DiningGuide example from the Java Studio Enterprise Tutorials and Code Camps:
http://developers.sun.com/prodtech/javatools/jsenterprise/learning/tutorials/index.html
I am using Studio6 with Application Server 7 update 3 with Java WSDP 1.3 [JAX-RPC 1.1 support]
The question is how does Studio support JAX-RPC DII client development ? I understand that the config.xml file is different between Static stub based client and a DII client. Please let me know as to how to configure
Studio to do this.
Below is the code that is new in the DIIClient shown in 3 sections:
- imports area in CustomerReviewTable.java
- getCustomerReviewByName method in CustomerReviewTable.java
[Basically taking the code from
http://java.sun.com/webservices/docs/1.0/tutorial/doc/JAXRPC6.html#75222
and modifying this to use this service and make appropriate
changes for the return value (Vector).
I suspect that this is where the problem is but need help to fix
it. - Thanks!!]
- Variables declaration new for DIIClient
- The WSDL for the DGWebService service is also shown
I tried it with both JAXRPC 1.0 and JAXRPC 1.1 [Setting this for the
Service in Studio 6] and regenerating the Service code
but did not see any difference.
Right now, with the code shown below, I do not get any exceptions, but
it doesnot show any reviews [Vector returned is null].
Really appreciate your help,
Sridhar.

Missing classes from servicegen client jar

If you generate the WSDL, stubs, etc from an EJB jar, not all the required classes
are copied to the service_client.jar.
If your EJB method takes a class (say HomeAddressDTO) and that class inherits from
a base-class, AddressDTO, then the AddressDTO is not included in the client jar.
Regards,
Nick

if you want to use the same classes on both client and server side
pls set useservertypes=true in the client element of servicegen.
It seems wls 7.0ga is not adding base classes for value types to
the client.jar file. I have filed a CR on this bug. Hope this will be
fixed for sp1.
Anyway, it is ok to add more classes to the client.jar manually.
You may have to do it when reflection cannot find all the required
classes or if you want to add your client app specific classes.
regards,
-manoj

I have the same problem. Do you think it is a bug? AFAIK, the processlooks
like this: value objects --> WSDL --> client-side stubs for value objects,
that actually do not have much in common with original ones. As I
understand, it is possible either to copy manually created value objectsto
client JAR file (no portability to non-Java clients), or to generate these
stubs from WSDL. There is a parameter for clientgen task which changes the
default behaviour. In my case all the parent classes in my value object
hierarchy are not "mirrored" in client JAR. I think that this is correct,
because client stubs do not have any hierarchy in them, they are just flat
structures.
I added needed classes to client JAR manually, but I think that this is my
personal design error that I need these classes.
What do you think?
Michael.

Deployment error - Missing class: javax.servlet.jsp.jstl.core.Config

Hi,
We are using JDeveloper 10.1.3.0.4(SU5) on windows for development of ADF application. We need to deploy the developed application onto Oracle Application Server 10g (10.1.3) which is running on Solaris. We are using BC4J, WAR and EAR deployment profiles in jdeveloper to create the .war and .ear files.
If I deploy the generated ear on a standalone OC4J server install on my windows PC, it works fine.
Now when I deploy the generated .ear file onto the Oracle Application Server 10.1.3 through Application Server Control interface and then try to access the jspx pages under our application we are getting following error:
oracle.classloader.util.AnnotatedNoClassDefFoundError: Missing class: javax.servlet.jsp.jstl.core.Config Dependent class: com.sun.faces.application.ViewHandlerImpl Loader: accaweb.web.accaweb:0.0.0 Code-Source: /oracle/app/oracle/product/10gas3/j2ee/home/applications/accaweb/accaweb/WEB-INF/lib/jsf-impl.jar Configuration: WEB-INF/lib/ directory in /oracle/app/oracle/product/10gas3/j2ee/home/applications/accaweb/accaweb/WEB-INF/libThe missing class is available from the following locations: 1. Code-Source: /oracle/app/oracle/product/10gas3/j2ee/home/default-web-app/WEB-INF/lib/jstl.jar (from WEB-INF/lib/ directory in /oracle/app/oracle/product/10gas3/j2ee/home/default-web-app/WEB-INF/lib) This code-source is available in loader default.web.defaultWebApp:0.0.0. at oracle.classloader.PolicyClassLoader.handleClassNotFound (PolicyClassLoader.java:2051) [oracle/app/oracle/product/10gas3/j2ee/home/lib/pcl.jar (from system property java.class.path), by sun.misc.Launcher$AppClassLoader@1482257]
I have confirmed that the .war file inside the .ear file does contain the jstl.jar file under WEB-INF/lib folder. And the jar file does contain the class 'javax.servlet.jsp.jstl.core.Config'
As a workaround, I found that if I copy the jstl.jar file from default-web-app to my application web-inf/lib folder, things start to work fine. ie copy from: '/oracle/app/oracle/product/10gas3/j2ee/home/default-web-app/WEB-INF/lib/jstl.jar'
to: '/oracle/app/oracle/product/10gas3/j2ee/home/applications/accaweb/accaweb/WEB-INF/lib/'
– or –
Another workaround is to add the '/oracle/app/oracle/product/10gas3/j2ee/home/default-web-app/WEB-INF/lib/jstl.jar' file in the classpath for my web application through Application Server Control setting page.
Now both of these workaround needs us to perform additional post deployment steps which should really not be required since the jar files is included in the project.
Has anyone faced this issue? Any pointers in this respect will be a great help.
regards - rutwik

Surprise Surprise !
I just tried deploying the file via uploading it from the Application Server Control UI and it worked fine.
Till now, I was ftp'ing the ear file from my PC to the server on which Oracle AS is running and was telling Application Server Control to pick form that uploaded location.
I am still not clear on why it works with HTTP upload and not via the FTP upload?

Error while enabling two way authentication :Client certificate missing

Hi,I am getting the following error while enabling the two way authentication.The weblogic server 5.1 has accepted both the client ca and server certificates and is listening for SSL on the specified port.But when I try to access thru the secured connection thru my IE it asks for Client Authentication dialog asking for valid Client certificate but I am not able to view any of the client certificate even though I have one which is the trusted root store.and there by giving the error page cannot be displayed .On the server side I get the following error.Thu Mar 08 10:54:35 GMT 05:30 2001:<D> <SSLListenThread> Problem accepting connectionjava.io.IOException: required client certificate missing at weblogic.security.SSL.SSLSocket.serverInit2(SSLSocket.java:711) at weblogic.security.SSL.SSLSocket.serverInit(SSLSocket.java:529) at weblogic.security.SSL.SSLSocket.initialize(SSLSocket.java:219) at weblogic.security.SSL.SSLSocket.performAcceptHandshake(SSLSocket.java:192) at weblogic.security.SSL.SSLSocket.getInputStream(SSLSocket.java:1001) at weblogic.socket.ResettableSocket.<init>(ResettableSocket.java:30) at weblogic.socket.JVMSocketManager.accept(JVMSocketManager.java:377) at weblogic.t3.srvr.ListenThread$RJVMListenRequest.execute(ListenThread.java:506) at weblogic.kernel.ExecuteThread.run(ExecuteThread.java, Compiled Code)can anybody please guide me what could be wrong.Do I need to change the browser settings.I have enabled SSL 3.0 and SSL 2.0 and all other settings are defaultIt is urgent.pls give some suggestions.Regards,Bhavani

I think you have to specify the client root in your weblogic.properties
file.
here are my settings:
weblogic.security.enforceClientCert=true
weblogic.security.certificate.server=democert.pem
weblogic.security.key.server=demokey.pem
weblogic.security.certificate.authority=ca.pem
weblogic.security.clientRootCA=VeriSignClass1CA.der
