  • Temporary License: Apply for a temporary license if you need full access during development.
  • Purchase: For long-term use, purchase a commercial license from GroupDocs.

Basic Initialization and Setup

Here’s how to initialize the Signature object:

import com.groupdocs.signature.Signature;

String filePath = "YOUR_DOCUMENT_DIRECTORY";
final Signature signature = new Signature(filePath);

Implementation Guide

In this section, we’ll focus on retrieving document process history using GroupDocs.Signature.

Retrieve Document Process History

Overview

This functionality allows you to access and display detailed logs of operations performed on a document. It’s useful for audit trails or debugging purposes.

Step-by-Step Implementation

1. Import Necessary Packages

Ensure these packages are imported at the beginning of your Java file:

import com.groupdocs.signature.Signature;
import com.groupdocs.signature.domain.ProcessLog;
import com.groupdocs.signature.domain.documentpreview.IDocumentInfo;
import com.groupdocs.signature.exception.GroupDocsSignatureException;
2. Initialize Signature Object

Define the path to your document and initialize the Signature object:

String filePath = "YOUR_DOCUMENT_DIRECTORY";
final Signature signature = new Signature(filePath);
3. Retrieve Document Information and Logs

Attempt to retrieve the document information including process logs:

try {
    IDocumentInfo documentInfo = signature.getDocumentInfo();
    
    // Iterate through each process log entry
    for (ProcessLog processLog : documentInfo.getProcessLogs()) {
        String operationDetails = "- operation [" + processLog.getType() 
            + "] on " + processLog.getDate().toString()
            + ". Succeeded/Failed " + processLog.getSucceeded() + "/"
            + processLog.getFailed() + ". Message: " + processLog.getMessage();
        
        // Check if there are signatures associated with this log
        if (processLog.getSignatures() != null) {
            for (BaseSignature logSignature : processLog.getSignatures()) {
                String signatureDetails = "\t- " + logSignature.getSignatureType()
                    + " #" + logSignature.getSignatureId() 
                    + " at " + logSignature.getTop() + " x "
                    + logSignature.getLeft() + " pos;";
                
                operationDetails += signatureDetails;
            }
        }

        // Display the operation details
        System.out.println(operationDetails);
    }
} catch (GroupDocsSignatureException e) {
    e.printStackTrace();
}

Explanation of Parameters and Methods

  • filePath: The path to your document.
  • signature.getDocumentInfo(): Retrieves information about the document, including process logs.
  • processLog.getType(): Returns the type of operation performed.
  • processLog.getSucceeded()/processLog.getFailed(): Indicates if the operation was successful or failed.

Troubleshooting Tips

  • Ensure your document path is correct and accessible.
  • Handle GroupDocsSignatureException to catch potential errors during execution.

Practical Applications

Here are some real-world use cases for retrieving document process history:

  1. Audit Trails: Track changes made to legal documents or contracts for compliance purposes.
  2. Debugging: Identify issues in the document processing pipeline by reviewing logs.
  3. Integration with Workflow Systems: Use log data to automate approval workflows based on specific actions performed.

Performance Considerations

Optimizing Performance

  • Batch Processing: Process multiple documents in batches to reduce overhead.
  • Efficient Logging: Only retrieve and process essential log details to minimize resource usage.

Resource Usage Guidelines

  • Monitor memory consumption when handling large documents or numerous logs.
  • Use efficient data structures for storing and processing log information.
