This is my service public String generateOMR(MultipartFile sourceFile, String fileName) {
try {
createDirectories();
String sourceFilePath = saveUploadedFile(sourceFile);
LoadLicenseFromFile.run();
OmrEngine engine = new OmrEngine();
GenerationResult result = engine.generateTemplate(sourceFilePath);
result.save(OUTPUT_DIR, fileName);

        return "Form generated successfully";
    } catch (Exception e) {
        return "Error generating form: " + e.getMessage();

It seems that you are encountering an issue where the generated OMR sheet is blank. This can happen for several reasons, and I will guide you through some troubleshooting steps to help resolve this issue.

Check the Source File: Ensure that the content in your .txt source file is correctly formatted according to the specifications required by the Aspose OMR library. Any syntax errors or misconfigurations in the markup can lead to a blank output.
Verify the File Path: Make sure that the path to the source file is correct when you are saving it. If the file is not found or not accessible, the OMR engine will not be able to generate the template.
Inspect the Generation Result: After calling the generateTemplate method, check the GenerationResult object for any error codes. If there are errors, they can provide insight into what went wrong during the generation process. You can add a check like this:
```
if (result.getErrorCode() != 0) {
    System.out.println("ERROR CODE: " + result.getErrorCode());
}
```
Output Directory: Ensure that the output directory where you are saving the generated OMR sheet is correctly set up and writable. If the application does not have permission to write to the specified directory, the output will not be saved.
Testing with Sample Files: Try generating the OMR sheet using a known working sample file provided in the Aspose OMR examples. This can help determine if the issue lies with your specific markup or the generation process itself.
Review Documentation: It may be helpful to review the official documentation or examples provided by Aspose OMR to ensure that your implementation aligns with the expected usage.

If you follow these steps and still encounter issues, please provide any error messages or additional details about your setup, and I would be happy to assist further!

Hello, @amarschool

I have noticed that in thread tags there is a mention of Aspose OMR for Java.

Unfortunately, at the current moment, Java version has very limited API.

More complex layout element (container\block\paragraph) as well as behavior patterns (wrap\clip) - only available on .NET or Cloud solutions.
