I'm new to WSO2 products, I know while integrating BPS with ESB, we require the service of deployed Process
so My Question is:- Where to Find Web Service of Deployed BPM.
Deploying a BPM does not result in a Webservice, one or more processes will be deployed instead. You can find these under processes in the BPMN explorer https://[wso2server]:[port]/bpmn-explorer or they can be accessed through the BPMN rest API REST API Documentation.
If you want webservices that implement processes you should probably go with (WS-)BPEL. BPEL Reference
If you want to start/control the process from your webpage you can use the rest API. To start a process using the API you would send a POST request to the following URL:
https://<Host Name>:<Port>/bpmn/runtime/process-instances
This will create a new instance of the process you have specified in the Request body. All you need to put in the body to create the instance is either the processDefinitionId or processDefinitionKey (you can find both in the BPMN-explorer mentioned above). There are other, optional variables as well as the option to create your instance based on a message but this last option is not recommended.
{
"processDefinitionKey":"sampleJavaServiceTask"
}
For more info on this, check out the link to the BPMN REST API

I am trying to do a POC where i need to invoke a Stateful SOAP webservice . I need to do a login call first to SOAP webservice and get the session id(or cookie or something like that) and use the session id for making subsequent calls to the webservice . I want to know if there is any sample stateful SOAP webservice hosted on the internet for which i can generate the client and try invoking the webservice to verify Stateful operation. Any other pointers on how i can do this is also very welcome.
If this POC is successful we will be invoking a Stateful SOAP webservice hosted by one of our vendors and we will be using a TIBCO BW client to call the SOAP webservice.
You can invoke the WebServiceDefinitionLanguage from the WSDL attached in the link It brings encouraging quotes.
You may use SOAP activity in BW or import the WSDL as a resource first and then use any SOAP or web service activity.
Check this java project in github is a multi cloud java project that invokes WebServices and Rest services from many Cloud providers and Many sites. It gives you an idea on how to do it.
Of course in BW is really easy to do it. Basically: start activity, SOAP activity, log, call subprocess, catch errors, end process.
Stateful or Stateless SOAP webservice call is just like any another web-service call. In your case, since you have to get the response(i.e. receiving token) of the first webservice call and use it in the subsequent calls, I think you should focus on how would you cache the cookie/token that you receive from the first call. Also, if there is an expiry associated to the life of the token received in your response, work on the technique of refreshing the token for which the SOAP API provider will have to provide you an token expiry interval.
I know a service task of BPMN can send messages (JMS or WS calls) to external system using camel or mule in Activiti, but it seems that there's no camel or mule supported in WSO2 BPS, and I'm afraid it is because WSO2 ESB can substitute for them. So, my question is how can a service task send messages to WSO2 EBS?
Obviously, I can create a Java class implementing JavaDelegate class for a service task and write some codes for sending messages in execute method, but I want to know whether there's some "smart" solution..
Thanks a lot.
BPMN service task would be the solution in this case as you have mentioned. What type of service call do you need to do in ESB? If it's a REST API invoke in ESB, you could use the REST TASK extension available in WSO2 BPS. You could find a good use case on this in example
For example, you could add a Service Task with Task Type: Java Class
Class Name: org.wso2.carbon.bpmn.extensions.rest.RESTTask
with following fields.
serviceURL - rest service endpoint
method - http method to use
basicAuthUsername - username if the endpoints are secured
basicAuthPassword - password for the username above
input - payload to be sent
outputVariable - process variable to save the response
header values in the format "key1:value1,key2:value2"
Here's the scenario,
WS_A and WS_B are Web Services published in different endpoints.
WS_A receives personId, makes some processing, logs some data, and returns the name and the lastname of the Person with personId.
WS_B receives two Strings name and lastname and saves name+lastname in a database, then returns Ok/Error.
I need to publish an API API_Composition, using WSO2 API Manager, that will call WS_A, and send the result to WS_B, then return the result of WS_B.
Keep in mind that i can't make a new WS_C that has the behaviour of WS_A+WS_B, because i can't access the whole code of any of them.
Is there a way of doing this using only WSO2 API Manager?
Are there any other API Management products that can accomplish this requirement?
Regards
Yes, you can do this with mediator sequence. I have not found a specific tutorial for your scenario, but here's a blog post that has a demo on using mediator sequences and links to detailed documentation.
(Note: the demo and blog post are for WSO2 API Cloud - the hosted version of WSO2 API Manager. But it all works the same for API Manager - it is the same technology.)
I have an asmx web service running in a Web Role in a Windows Azure cloud application. I want to user the Windows Azure scheduler to call this service on an hourly basis. I am able to create the job but everything I have tried in the URI results in an error.
I can call the same web service successfully from a web page using ajax using a URI such as :
http://www.example.com/myservice.asmx/TheFunction
but this form returns an error (when I use either a GET or a POST):
Request format is unrecognized for URL unexpectedly ending in '/TheFunction'.
Can anyone advise what format this URI should take?
Thanks
Don't know if this will help, but our team found that if you're using the brand new Management screens from the Azure Portal to do this, you can only set the URL and the Content, but you don't appear to have access to the request headers.
We were calling into an MVC application, and found that we need to add a header variable (Content-type: application/x-www-form-urlencoded) in order for our Router / Controllers to pull the associated POST arguments. We're looking at using the API to create the job instead, as there appears to be control over the headers using this method.
See the "headers" argument within the
Create Job Method in the Scheduler API.
How can i use StatisticsAdmin of Application Server
My scenario is : i want to get responsetime of a service that deploy on a server(AppServer/DataServer..) and probed by ESB using discoveryproxy of governance regidtry. if is it possible how can i implement it? otherwise i should be get service response time from AppServer in direct using service name. i can create a proxy of ServerAdminMBean using this package and interface
import org.wso2.carbon.server.admin.service.ServerAdminMBean
but i need to use attributes and method of StatisticsAdmin type. how can i implement it?
you dont need to do your own implementation. it is already in the service statistics page.
You can find the service stat details in the monitor-->System Statistics page. If you need more fine grained details about your service,you might need to integrate BAM with AS.
Once you deploy any service, there's a log message prints in server back end console.(you may noticed that before). That message handled by the "LoggingAdmin" admin service. In that admin service there's a operation called "getSystemLog" and this operation sends all log messages one by one. you can create simple java class to call that admin service and get the deployed time stamp of each of the service you are deployed. if you know the service deployment start time, with above admin service you can get time taken to each of the service deployment.
You can use JMX to access those information. There is StatisticAdmin MBena available for monitoring in . You can refer this to get an idea how to invoke them using Java.
