Invocation API or Java Client Libraries

Hi All,
I want to invoke my short/long lived processes through my java code.
Now, There are two ways to achieve this as i know .
1. Invocation API (which I am using currently now)
2. java client libraries
Now my question is whether one can use java client libraries to invoke workbench processes through java code?
If yes, is it better than Invocation API ?
Thanks
Abhiram

Abhiram,
You can invoke any service defined to LC (there are several exceptions for good reasons) whether they are out-of-the-box services or applications you have built yourself.
In my opinion, your preference for invocation should be based upon the best fit for your existing Java classes. That's the beauty of the LC APIs. They give you some flexibility. The invocation APIs are nice for dealing with documents (PDF and native file formats). However, if your Java class(es) use Web Services then use the SOAP endpoint to call the LC process, for example. If performance is an issue and the Java class(es) run on the same host as LC, then use EJB.

Hi All,
I am new in this group, and I need to help me to develop a java client to communicate with metasolv application using XML API.
I read "XML API Developer’s Reference" document, but I still not understand how can I setup the cllient.
I still need:
1- What API needed(jar files) I must use to build the client
2- A sample of source code using java.
3- detailed guide to communicate with metasolv application using XML API.

Oracle BPEL Java Client API: Reading Configurations dynamically

We have a requirement to use Oracle BPEL Java client API to control the BPEL instances at the runtime, from an ADF BC Application. is there any possibility to read the configurations/properties that are required to look up (using 'oracle.soa.management.facade.Locator' ) the BPEL Process Manager/Server from connections.xml/adf-config.xml ?
In other terms, as we need the details like the bpel server URL, security credentials..etc to lookup the BPEL server and instances using the BPEL java client API, how can we read these details from the ADF standard config files like Connections.xml/adf-config.xml instead of hard coding them in the Java program.
Edited by: 899479 on Feb 4, 2013 6:02 AM

The api's for BPEL / Workslow canbe found here:

VC8 clients and native invocation API

Hi,
Could someone from Sun tell me whether JNI invocation API for the 1.5.0_07 Windows JVM supports .NET clients compiled with Visual C++ 8?
I have an ASP.NET application that calls into the JVM through the JNI invocation API. I know that there were problems with VC7 clients calling into the 1.3 and 1.4 JVM's (they only surfaced under high concurrency), but I was told that the 1.5 JVM would better support .NET clients.
Thanks...

Problem getting calendar event with recurring using EWS Java client API 1.2

I am using EWS 1.2 Java client API for getting calendar events. I am able to get Recurring information of the event which is created through API's
appointment.save(), but not able to get recurring information of the event created in OWA interface, I get following error during the bind:

============================
This happens if I use: Appointment.bindToRecurringMaster or Item.bind(service, id, appointmentProps) or findAppointments().
Works fine for events which doesn't have recurring. Only issue with events containing recurrence created through OWA. These are the propertySet:
new PropertySet(BasePropertySet.IdOnly,
ItemSchema.Subject,
AppointmentSchema.AppointmentType,
AppointmentSchema.DeletedOccurrences,
AppointmentSchema.FirstOccurrence,
AppointmentSchema.LastOccurrence,
AppointmentSchema.IsRecurring,
AppointmentSchema.Location,
AppointmentSchema.ModifiedOccurrences,
AppointmentSchema.OriginalStart,
AppointmentSchema.Recurrence,
AppointmentSchema.Start,
AppointmentSchema.End);
If I remove Recurrence it gives the response.
Thanks.

Java Client Program to explore CVS Repository

Hi Friends :
My module, use CVS as repository to which bunch of XMLs files gets committed by a particular process. Later these XMLs are collected and send to another location by an EOD process.
I need to write a java client, to explore CVS file folder structure to see what is in the CVS before EOD process starts. I do got one reference from NetBeans Stack - org-netbeans-lib-cvsclient.jar - but faces limitations on them.
Has any one here, has got any suggestion / alternate approach to make.
Regards
Abhilash

Imagine some friend replied to me - "Oh yes - I have applied this - XYZ jar in my project for same ops.. ' - this would have been booster for any one experimenting with ...That is what expected rather than de-route to Google Path .. My point is, that a Google search will probably lead you to articles, blogs, and posts, on this forum or on others, from people that are applying succesfully XYZ.jar for a similar purpose. This forum, with all due respect to its venerable members, and despite my obvious bias and sympathy for some of them, are no more authoritative than a few other technical places on the Internet.
And if no such existing resource andwser your needs, you'll be more welcome if you state that "you have read XYZ's doc, read this post (link), and this one (other link), and evaluated this other lib, and none of them seems to fulfills my requirements X, Y, and Z"
I have noticed your similar reply for the same query in another postAh, you mean in this topic which you resurrected (wink to the moderators :o): {message:id=9817389}?
Well note that it was not me who pushed this other poor soul to a search engine, so this is not just me getting old, wrinkled and bitter, merely a general consensus here that questions such as "Looking for a way to..." should demonstrate some effort on the part of the questioner before asking others. In the case of such an request where obviously several APIs are easily found, you could read the introduction chapter of the respective docs, to get an idea of the strength and weaknesses, or do a few more searches to find posts related to these APIs on programming forums.
but I feel - any query can give different dimensions of issuesI don't understand :o(
Idea of using CVS in my java module for storing files for processing came to my attention (...) remotely related to my requirement (...) It triggered me using CVS (...) would give me added advantagesIn other words, using CVS is not a requirement, it's a technical decision, after analyzing the requirements and the other factors that can drive the choice (licence cost, knowledge within the team, maintenability,...)?
Unless history, branching, and diffing, are requirements of your application, I seriously question using CVS as only a shared repository of data, but let's assume you have done this analysis and indeed come to the right conclusion.
So am patient enough to get an valuable guidance / lead on same subject - else I will continue with POC !!
Good Luck Oh you mean, with my age, wrinkles, and bitterness? Thanks ;)
I didn't mean to offend you, and wish you good luck getting help, I just pointed out that you will have more chance of getting help if you:
1) give more details about which "limitations" are hampering your work:
2) demonstrate more effort of evaluating alternative solutions
For example it is not clear to me if you're looking for a workaround with your current library, or if you 're looking for alternative libraries.

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.

How can i execute Spaces API in java main class?

Hi
I am able to execute Spaces API through portal application. However if i try to execute it in java main class, its throwing an exception
"SEVERE: java.io.FileNotFoundException: .\config\jps-config.xml (The system cannot find the path specified)"
oracle.wsm.common.sdk.WSMException: WSM-00145 : Keystore location or path can not be null or empty; it must be configured through JPS configuration or policy configuration override.
How can i set this path, so that i can execute Spaces API from java main class.
Need this main class to configure in cron job, to schedule a task.
Regards
Raj

Hi Daniel
Currently i have implemented create functionality in my portal application using Spaces API, which is working fine. Now the requirement is, i need to implement a "Cron Job" to schedule a task, which will execute to create space(for example once in a week). Cron job will execute only the main method. So I have created java main class, in which I have used Spaces API to perform create space operation. Then it was giving exception.
Later I understood the reason, as I am executing the Space API with a simple JSE client, its failing since a simple java program has no idea of default-keystore.jks, jps-config.xml, Security Policy. Hence i have included those details in main class. Now I am getting new error,
SEVERE: WSM-06303 The method "registerListener" was not called with required permission "oracle.wsm.policyaccess"
For your reference i have attached the code below, please help. How can i use Spaces API in java main method(i mean public static void main(String[] args) by giving all required information.
    public static void main(String[] args) throws InstantiationException,
                                                  GroupSpaceWSException,

Creating multiple stateful session beans from a java client. (EJB 3.0)

I'm having difficulties with the following:
To access the ShoppingCartBean, I have to put the following annotation in my standalone java client:
@EJB
private static ShoppingCartRemote shoppingCartBean;
The static must be there, thus only one ShoppingCartBean will exist within my java client. But as the ShoppingCartBean is a stateful session bean, I want to be able to get different beans of the same type.
What is the correct way to do this in EJB 3.0?

Great question. Because Home interfaces have been removed for the EJB 3.0 simplified
API, stateful session bean creation happens as a side-effect of injection. However, the
same is true of EJB 3.0 business interface lookups. The easiest way to create additional
stateful session beans is to lookup the same dependency that was declared via your
@EJB annotation.
E.g.,
// Assuming the declaring class is pkg1.ShoppingCartClient.java
InitialContext ic = new InitialContext();
ShoppingCartRemote scr1 = (ShoppingCartRemote)
ic.lookup("java:comp/env/pkg1.ShoppingCartClient/shoppingCartBean");
Note that the name relative to java:comp/env is the default associated with your
@EJB annotation since the name() attribute wasn't used. Alternatively, you
could have used :
@EJB(name="scb") private static ShoppingCartRemote shoppingCartBean;
InitialContext ic = new InitialContext();
ShoppingCartRemote scr1 = (ShoppingCartRemote) ic.lookup("java:comp/env/scb");
Yet another alternative is to declare the @EJB at the class-level. This just defines
the dependency without any injection, which is fine if you want to create a bunch of
them via lookup anyway.
@EJB(name="scb", beanInterface=ShoppingCartRemote.class)
public class .... {

Invoking a secure web service from a standalone java client

I am using stand alone java client to invoke a web service. This web service in turn invokes a jcs which is protected ( role based access ).
I am using a proxy at the client side for web service invocation
FileSubmission_Impl filesubmission_impl = new FileSubmission_Impl();
FileSubmissionSoap filesubmissionsoap = filesubmission_impl.getFileSubmissionSoap();
filesubmissionsoap.processFiles(...)
This works if there are no security constraints on any of the resources (@common:security).
I need to pass the username and password from the java client that will be authenticated and allowed to access the protected resources.
Please let me know as to how this can be achieved ( passing username and password from client )

Paula,
I suppose you're using CFINVOKE (http://www.activsoftware.com/code_samples/code.cfm/CodeID/44/ColdFusion/Invoking_SOAP_Web_Services_with_ColdFusion_MX_CFINVOKE_Tag) or are you using a third party tool like CFX_SOAP (http://www.activsoftware.com/products/productdetail.cfm/id/1015)?
Are you working with WebAS 6.4 or 6.2?
It works with web services created with WebAS 6.4, but you should generate proxy classes. Check Thomas' weblog (second part of it)->https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/1012. [original link is broken] [original link is broken] [original link is broken] [original link is broken] [original link is broken] [original link is broken] [original link is broken] [original link is broken] [original link is broken]
The WSDL generated by this method is more standard than the one generated when you just Remote enable an FM and look at the webservice browser.
Th core of CF MX is Java and that engine is rather strict in standards.

How to deal with credentials for external applications using a Java Client/

Hi Guys,
This is the case. I am integrating an external application with an ADF Application. I have implemented some programmatic ViewObjects that are being filled up by a REST Java Client Wrapper. Everything is working fine but the issue is that the credentials the wrapper is using are hard coded inside the java class. I am thinking to ask for the credentials at the beginning of my taskflow and then store them somewhere and use them then to create my client wrapper (passing them in the constructor).
However, I don't know if my approach is good and I would like you to share your experiences or how to deal with this.
Regards

You can use Credential Store Framework to store the credentials securely in the weblogic server instead of hardcoding in the java class.
The Credential Store Framework:
- enables you to manage credentials securely
- provides an API for storage, retrieval, and maintenance of credentials in different back-end repositories
Check the documentation on CSF API -
http://docs.oracle.com/cd/E29505_01/core.1111/e10043/devcsf.htm
Major Steps -
1. Create a credential map and key in em console to store the password (http://docs.oracle.com/cd/E25054_01/core.1111/e10043/csfadmin.htm)
2. Use CSF API to retrieve the stored password
3. In jazn-data.xml give permissions to access CSF key and map

Custom OIM java client not working

Hi all,
I am trying to execute a custom OIM java client in my server. The java file just has the code to connect to the OIM server and it is failing at the line
ConfigurationClient.ComplexSetting config = ConfigurationClient.getComplexSettingByPath("Discovery.CoreServer");
The basic content of the java file OIMTry.java is given below:
env.put("java.security.auth.login.config", "/u01/apps/resetpwd/config/auth.conf");
env.put("java.security.policy", "/u01/apps/resetpwd/config/xl.policy");
env.put("XL.HomeDir", "/u01/apps/resetpwd");
ConfigurationClient.ComplexSetting config = ConfigurationClient.getComplexSettingByPath("Discovery.CoreServer");
env = config.getAllSettings();
I have set the OIM related jar files in classpath in .bash_profile and able to echo the classpath as well.
However, the file is executing perfectly in Eclipse tool but not from command prompt.The file is getting compiled properly at command prompt.
I have tried various options of executing the java file as shown below.
java -Djava.security.manager -DXL.HomeDir=/u01/apps/oim_server/xellerate -Djava.security.policy=/u01/apps/oim_server/xellerate/config/xl.policy -Djava.security.auth.login.config=/u01/apps/oim_server/xellerate/config/auth.conf -Djava.naming.provider.url=jnp://oim_server_host:12401/ OIMTry

Hi,
We were unable to create tcUtilityFactory instance when the env variables are set using the hashmap.
Instead it is working when we set using System.setProperty() as shown below:
System.setProperty("XL.HomeDir", "/u01/apps/OIMPwdReset");
System.setProperty("java.security.policy", "/u01/apps/OIMPwdReset/config/xl.policy");//server or client
System.setProperty("java.security.auth.login.config", "/u01/apps/OIMPwdReset/config/auth.conf");//server or client
Hope this helps other guys..
