Use of DOCDATA

RentProperty

Hi guys,

we are writing a plugin for AwareIM 5.8 to convert a base64 String to a image.
I'm able to convert the string to an image and create a local file. However I would like
to update the image attribute in the application with the new converted image. I understand
that I need to use the setBinaryMethod but can't get it to work properly. I get the following
error:

com.bas.basserver.executionengine.ExecutionException: Internal error. Error writing attribute
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server
version for the right syntax to use near '[B@1bafb1b WHERE ID=31' at line 1

Would appreciate any help or examples.

==== Here is my execute method =====

@Override
 public Object execute(IExecutionEngine engine, Object[] parameters)
   throws SuspendProcessException, ExecutionException,
   AccessDeniedException {

  if (parameters == null || parameters.length != 1
    || !(parameters[0] instanceof IEntity)) {

   return null;

  }

  IEntity entity = (IEntity) parameters[0];

  String base64ImageString = "";

  try {

   base64ImageString = (String) entity
     .getAttributeValue("Base64ImageString");

   base64ImageString = base64ImageString.substring(
     base64ImageString.indexOf(",") + 1,
     base64ImageString.length());

   byte[] imageByteArray = decodeImage(base64ImageString);

   //Test if image is converted => this works
   /*
    * FileOutputStream imageOutFile = new FileOutputStream(
    * "DecodedImage.png");
    * 
    * imageOutFile.write(imageByteArray);
    * 
    * imageOutFile.close();
    */

   //Set Picture Attribute in object
   engine.setBinaryData(engine.getExecutionContext(this).getProcess(),
     entity.getName(), entity.getId(), "DecodedImage",
     imageByteArray);


  } catch (Exception e) {
   e.printStackTrace();
  }

  return null;
 }

public static byte[] decodeImage(String imageDataString) {
  try {
   return Base64.decode(imageDataString);
  } catch (Base64Exception e) {
   

   e.printStackTrace();
  }

  return null;
 }

Thanks

Hi guys! I got it working... thought I'd share for future reference. Not sure if Aware IM already has this functionality?

Can simply use the setAttributeValue method to set the DOCDATA and DOCTYPE. The setBinaryData method was not needed after all. 🙂

	@Override
	public Object execute(IExecutionEngine engine, Object[] parameters)
			throws SuspendProcessException, ExecutionException,
			AccessDeniedException {

	if (parameters == null || parameters.length != 1
			|| !(parameters[0] instanceof IEntity)) {

		return null;

	}

	IEntity entity = (IEntity) parameters[0];
	String base64ImageString = "";

	try {

		// Get the base 64 string
		base64ImageString = (String) entity.getAttributeValue("Base64ImageString");

		// Get the base 64 part of the string
		base64ImageString = base64ImageString.substring(base64ImageString.indexOf(",") + 1);

		// Convert base64 string to byte[]
		byte[] imageByteArray = Base64.decode(base64ImageString);

		// Set the attribute values
		entity.setAttributeValue("DecodedImage.DOCTYPE", "yourimage.jpg");
		entity.setAttributeValue("DecodedImage.DOCDATA", imageByteArray);

		engine.updateEntity(this, entity);

		System.out.println("Image Converted");

	} catch (Exception e) {
		e.printStackTrace();
	}

	return null;
}

Cheers
Werner
