Upload zip file

Hi everyone!

I have been trying to upload a 44 MB zip file using tFileFetch, tRest and tHttpRequest but untill now no success.

Here is my settings for tFileFetch:

It's throwing the following error:

java.io.FileNotFoundException:File is not a normal file.

Hello,

Try once by setting the filename in a tJava before the tFileFetch as : String fileName = <Your FileName context>, then, in tJava only context.setProperty("FILE_NAME",fileName);

use the fileName context in tFileFetch : context.getProperty("FILE_NAME").

Thanks,

You can try globalMap.put and globalMap.get instead of context.setProperty and context.getProperty. Also, your schema values are not passed through the tJava* components so they will come out null the other end.

@nfz11 i'm new in talend. Can you explain what you mean by "your schema values are not passed through the tJava* components so they will come out null the other end"?

Also when i use globalMap it throws the error: "The constructor File(Object) is undefined"

Can you show a screen shot of your code where the you are setting the File(Object)?

I mean that if you put a tJava* component in your flow, it does not persist the values in schema to the other side, unlike say, a tLogRow.

[id=1,name=John] -> tJava* -> [id=null,name=null]
[id=1,name=John] -> tLogRow -> [id=1,name=John]

I'm not setting any file object. I only set the file name in the tjava. Shouldn't talend create the file object itself when i check the upload file checkbox?

Also how can persist the values in schema to the other side?

Hello,

globalMap.get() returns an object.

Please cast to string like (String)globalMap.get("FILE_NAME")

Thanks,

@subhadip13 thanks for replying.

I try to post the file to server using postman and it works fine. Here are my postman settings:

In talend it's throwing the following error:

java.net.SocketException:Connection reset by peer: socket write error

What can be causing this?

PS: the file size is 44MB.
