Changing a file extension from list

RA6 — Sat, 16 Nov 2024 08:05:05 GMT

Hello,

I have a directory which contain several xml files and 1 file with (.tmp) extension.

I am trying to rename or replace the toTest.tmp to toTest.xml using a tfilelist and a tjava.

My tfilelist:

My tjava codes:

((String)globalMap.get("tFileList_3_CURRENT_FILE")).replace(((String)globalMap.get("tFileList_3_CURRENT_FILEEXTENSION")), "xml");

The job is ending without error but the file renaming is not taking place.

Can you suggest please?

Thank you.

using tjava is not the best way.
using tjava is like coding in java.
talend is easy to update if it's visual.

if you want to use tjava go to a java forum.

@rhall

Since, there is a component in talend named "tjava", i have tried to use it.
I have posted my job example in the previous post. Can someone tell me what is wrong please?

Thank you

You tJava seems incomplete and as mentionned by @fdenis this is not the best way as soon as you have a component to do what you expect.

globalMap.put("newFileName",((String)globalMap.get("tFileList_3_CURRENT_FILE")).replace(((String)globalMap.get("tFileList_3_CURRENT_FILEEXTENSION")), ".xml");

but tjava is to use only if you cannot do by an other way.

I found a solution:

// File (or directory) with old name
File oldfile = new File(((String)globalMap.get("tFileList_4_CURRENT_FILEPATH")));

// File (or directory) with new name
File newfile = new File(((String)globalMap.get("tFileList_4_CURRENT_FILEPATH")).replace(((String)globalMap.get("tFileList_4_CURRENT_FILEEXTENSION")), "xml"));

// Rename file (or directory)
boolean success = oldfile.renameTo(newfile);

Hi @Rohit Aftab

i'm facing the same issue to change the file extension and i've tried this code in tjava. However, i'm getting error saying that "File cannot be resolved to a type"

Did you face the same error before or no? Do you have any idea about this?

Thank you

Please try importing "java.io.File"
