我正在使用 CoSign 开发人员帐户，并且创建了多个图形签名。我正在使用示例代码对 pdf 文件进行签名，它可以工作，我能够枚举签名，但我无法弄清楚如何从帐户的签名列表中指定要使用的签名。

使用的代码示例：

package trial;

import com.arx.sapiws.dss._1.*;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.List;

import oasis.names.tc.dss._1_0.core.schema.DocumentType.Base64Data;
import oasis.names.tc.dss._1_0.core.schema.*;
import oasis.names.tc.saml._1_0.assertion.*;

public class MultipeSignatures {

    public static void main(String[] args) throws Exception {

        String fileName = "D:/demo - Copy.pdf";
        String signerUsername = "";
        String signerPassword = "";

        if (!checkFile(fileName)) {
            System.out.println("Cannot find '" + fileName + "' or it is read/write protected. Aborting.");
            return;
        }

        // Get all user's graphical signatures
        List<GraphicImageType> gSignatures = listGraphicalSignatures(signerUsername, " ", signerPassword);
        for (GraphicImageType image : gSignatures) {
            System.out.println("image: " + image.getGraphicImageName());
        }

        SignPDF(fileName, signerUsername, signerPassword);
    }

只需获取首选图形签名的名称并按照我对您之前问题的回答中的描述进行设置。
