How to allow a file_path parameter to be selected by browsing folders instead of typing?

Anonymous — Wed, 07 Aug 2019 14:06:55 GMT

Hi,

I have made a processor component which takes a file path as an input

I have defined it as a String parameter now:

@Option
@Documentation("TODO fill the documentation for this parameter")
private String input_path;

How can I make this parameter input the path by browsing they file system, like in the case of a tFileInput* component:

the "File name/ Stream" parameter.

I tried declaring the parameter under

@Option("file-path")

which I saw briefly mentioned in the documentation, and changed the parameter type to "File", but it didn't change anything. I can't find any documentation on how to do this though. What should I change to get this done?

Thanks,

Siva

Hello,

You could define a context variable and assign a default file path to it, set the File name/stream field of tfileInputExcel in context variable like:

Hello,

If your input file changes frequently and you cannot define in context variable as I said.

Please use tFileList component to iterate all the files that matches the file mark you define.

Hi,

My question is regarding a custom component that I have created. That's why I had posted in Component Development board.

I want to know how to input a file directly by browsing and selecting it from the computer. Currently I am taking the file path as an input (String type) and then reading the file.

Thank You.
