Hello,

It seems you are showing ColdFusion code. https://helpx.adobe.com/coldfusion/developing-applications/using-web-elements-and-ex[…]nd-java-elements-in-cfml-applications/using-java-objects.html

What are you trying to achieve? Do you want to extract the Java logic from this ColdFusion page?

Best regards

Sabrina

yes ...

i got the the code in java,

import java.io.UnsupportedEncodingException;

import java.security.MessageDigest;

import java.security.NoSuchAlgorithmException;

import java.security.Timestamp;

import java.util.Date;

String apiKey = "test";

String secret = "test";

Date date= new java.util.Date();

Long timestamp = (date.getTime() / 1000);

String signature = null;

try {

String toBeHashed = apiKey + secret + timestamp;

MessageDigest md = MessageDigest.getInstance("SHA-512");

byte[] bytes = md.digest(toBeHashed.getBytes("UTF-8"));

StringBuilder sb = new StringBuilder();

for(int i=0; i< bytes.length ;i++){

sb.append(Integer.toString((bytes[i] & 0xff) + 0x100, 16).substring(1));

}

signature = sb.toString();

} catch (NoSuchAlgorithmException e) {

e.printStackTrace();

} catch (UnsupportedEncodingException e) {

e.printStackTrace();

}

String authHeaderValue = "EAN APIKey=" + apiKey + ",Signature=" + signature + ",timestamp=" + timestamp;

then i want to call the variable "signature" in the header of "tRestClient" (for authentification"

but i got error

Hello

Move the import xxxx code to Advanced settings panel of tJava component.

In addition, there are two issues in your job design.

1 Use OncomponentOK or OnsubjobOK connector from tJava to tRestClient.

2 You should initialize the global variable before it is used, eg: in the end of tJava,

globalMap.put("signature",signature );

Hi @Shicong Hong

thanks for reply

Still can't get the variable in tRestClient.

the variable "sig" is a dynamic variable ..for every call to the routine "sig" will have a new value
