Hi Sriashalya,
You can use a class mediator to get the attachment. This code is used to
get the attachment and convert base64 encoding then assign to a property.
The property can be used in the template. Before that you need identify the
API support encoding.
Sample code for the attachment
public class Attachment extends AbstractMediator {
private static final Log log = LogFactory.getLog(Attachment.class);
public Attachment() {
}
public boolean mediate(MessageContext synCtx) {
SynapseLog synLog = getLog(synCtx);
if (synLog.isTraceOrDebugEnabled()) {
synLog.traceOrDebug("Start : Sample attachment mediator");
if (synLog.isTraceTraceEnabled()) {
synLog.traceTrace("Message : " + synCtx.getEnvelope());
}
}
try {
String contentId = getCotentIds(synCtx)[1]; InputStream
inputStream = getInputStream(synCtx, contentId); byte[] bytes
= IOUtils.toByteArray(inputStream);
String encodedString = Base64.encodeBytes(bytes);
synCtx.setProperty("attachmentBody", encodedString);
inputStream.close();
} catch (NumberFormatException nfe) {
synLog.auditWarn("sample adaptor - invalid value returned : "
+ nfe);
} catch (Exception e) {
synLog.error("sample adaptor - error generating the attachment
payload : "
+ e);
}
if (synLog.isTraceOrDebugEnabled()) {
synLog.traceOrDebug("End : Sample Attachment mediator");
String contentId = getCotentIds(synCtx)[1];
if (synLog.isTraceTraceEnabled()) {
synLog.traceTrace("Message : " + synCtx.getEnvelope());
}
}
return true;
}
//get the content Ids
public String[] getCotentIds(MessageContext synCtx) {
Axis2MessageContext axisMsglengthContext = (Axis2MessageContext)
synCtx;
org.apache.axis2.context.MessageContext msgContext =
axisMsglengthContext
.getAxis2MessageContext();
Attachments attachments = msgContext.getAttachmentMap();
return attachments.getAllContentIDs();
}
// get the input stream attachment
public InputStream getInputStream(MessageContext synCtx, String
contentID) {
Axis2MessageContext axisMsgContext = (Axis2MessageContext) synCtx;
org.apache.axis2.context.MessageContext msgContext = axisMsgContext
.getAxis2MessageContext();
Attachments attachments = msgContext.getAttachmentMap();
DataHandler dataHandler = attachments.getDataHandler(contentID);
InputStream inputStream = null;
try {
inputStream = dataHandler.getInputStream();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return inputStream;
}
}
<class name="org.wso2.carbon.connector.sample.Attachment" />
<property name="attachmentBody"
expression="get-property('attachmentBody')"/>
Thanks,
Kathees
