net.sf.json.JsonStandard cannot be resolved to a variable

Hi,

I changed my laptop and reinstalled Talend on the new laptop.

All my jobs are working, except one in which I use components tWriteJSONField and tRestClient :

I'm getting this message :

Talend version : TOS DI 7.3.1
Java : jre1.8.0_421
Configuration :

Environment variables :

Many thanks for your help

Hi,

It seems that the issue comes from the component tWriteJSONField, I did a test without using the component tRestClient and I have the same issue :

Hi @Fernandez

Could you maybe show the setup of your component ? You could be missing a jar

Alternatively, open the code view on Talend and click on the red square on the left side of the code. See what the code tell you, you can also share it here if you need help

What do you mean about "the setup of your component" ?

By the "setup of your component" I meant showing what it looks like inside

I have a more recent version of Talend Studio so I don't know what it should look like on your end, but on my side here are my jar file for tWriteJSONFields

Maybe you can try overriding it by manually installing this jar ?

In module view click on "Import external jar"

I don't have access to your link :

When I try to import, il appears on the tab :

But when I click on refresh, it disappears :

Did you click the button on the rigtht side of the tab with the three dots ?

On the line where you have the 2.4.5 lib click the three dots and then click the personalized MVN URI with this link

mvn:net.sf.json-lib/json-lib/2.4.8-talend/jar

and for the file select the file you have downloaded
