Trigger talend Jobs hosted on TAC by external Wso2 web services

[Anonymous]

Hi , 

I want external wso2 service trigger my talend DI job as soon as place a text file in server. I do not want to trigger the talend DI job from TAC by scheduling in every 5 min or do not want to use waitforfile task inside the Job.

Thanks for the details . But you are suggesting to use file based trigger than cron triggers on TAC . But I just want to know how a external WSO2 web service trigger my Talend job that is hosted on TAC . ( I dont want to use any TAC triggers ) . 

May be I have to expose my talend Job as web service so that Wso2 can trigger. Not sure.

Hi

I thought Abhishek just attach the wrong link, the proper is:

Invoking the Talend Administration Center API interactively

Yes Metaservlet API is your answer if you want to execute TAC job conductor tasks from external application.

Also, you can build your job as webservice with tBufferOutput . below links will help.

Thanks for the details. Is there any way we can send SOAP xml as input with API call to the DI job and DI job will store the information on Database. Input will be XML send by external Wso2 layer.

@vapukov : Thanks for your help . I have checked and it worked for me.

The Metaservlet API is not a SOAP API I'm afraid. Do you need to provide details to the job to enable it to run?

@rhall : Thanks for your reply . Yes That would be great if a Wso2 web service can invoke and send a SOAP XML as input and process the data through the Talend Job .

You cannot use a SOAP service to invoke the MetaServlet API unless you create a wrapper SOAP service which calls the MetaServlet for you. This is possible, but you will need to use the ESB product. Also, you can only supply context variable values to the jobs that you want to start. You *could* send your XML as a String to your jobs via a String context variable and then convert it inside the job. Why do you need to use SOAP?
