Example usage for javax.activation DataHandler writeTo

Introduction

In this page you can find the example usage for javax.activation DataHandler writeTo.

Prototype

public void writeTo(OutputStream os) throws IOException 

Source Link

Document

Write the data to an OutputStream.

If the DataHandler was created with a DataSource, writeTo retrieves the InputStream and copies the bytes from the InputStream to the OutputStream passed in.

Usage

From source file:org.wso2.carbon.registry.ws.api.utils.CommonUtil.java

public static byte[] makeBytesFromDataHandler(WSResource wsResource) throws IOException {
    DataHandler dataHandler = wsResource.getContentFile();
    if (dataHandler == null)
        return null;

    ByteArrayOutputStream output = null;
    //             OutputStream output = new FileOutputStream(tempFile);
    output = new ByteArrayOutputStream();
    try {/*from w  ww.  j  av  a  2  s .com*/
        dataHandler.writeTo(output);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        throw e;
    }

    return output.toByteArray();
