How to execute tFileCopy/tFileDelete from the tJava component

Anonymous — Fri, 23 Jun 2017 16:30:52 GMT

Hi All,

How can I execute components like tFileCopy and tFileDelete from within a tJava/tJavaFlex component. The idea is I would like to rename/move an input file based on certain conditions. My current sample code looks like below and it is obviously wrong because I don't know the sytnax for calling components from within tJava/tJavaFlex components.

I guess an alternative would be to use the tSystem compont within tJava, but I would run into the syntax problems as well. I am not particular whether I used tSystem or tFileCopy - I just want something that does the job.

**The code in the end code section of a tJavaFlex component:

if (num_rows > 0) {
    tFileCopy( ((String)globalMap.get("tFileList_1_CURRENT_FILEPATH")) ,
    context.error_dir + jobName + "/" ((String)globalMap.get("tFileList_1_CURRENT_FILE"))
    );
}

With the above code I get the error:

I don't think you can invoke other components from the custom code components. What you can do is set variables that are used by conditional trigger links.

Hello,

With your requirement, you can use "RunIf" trigger which triggers a subjob or component in case the condition defined is met.

You can add your code in the Condition section. Such as: Main job-->RunIf(num_rows > 0)-->tFileCopy.

Best regards
