OIBEE has ExternalReportWSSService webserive with method deliveryService to send pdf contents as an attachment. Only problem with this attachment always came with a default name as "ReportData"
I setup SOAP request to send a pdf to my email as below:
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:pub="http://xmlns.oracle.com/oxp/service/PublicReportService">
<soap:Header/>
<soap:Body>
<pub:deliveryService>
<pub:deliveryRequest>
<pub:contentType>application/pdf</pub:contentType>
<pub:documentData>abadadfasdfaf</pub:documentData>
<pub:emailOption>
<pub:emailBCC></pub:emailBCC>
<pub:emailBody>V1RG</pub:emailBody>
<pub:emailCC></pub:emailCC>
<pub:emailFrom>test@gmail.com</pub:emailFrom>
<pub:emailReplyTo>test@gmail.com</pub:emailReplyTo>
<pub:emailServerName>DefaultEmail</pub:emailServerName>
<pub:emailSubject>test</pub:emailSubject>
<pub:emailTo><EMAIL ID></pub:emailTo>
</pub:emailOption>
</pub:deliveryRequest>
</pub:deliveryService>
</soap:Body>
</soap:Envelope>
But not sure where to specify the attachment file name.
There was a defect in the WSDL. It worked when we put the pub:emailTo tag outside the pub:emailOption. Oracle acknowledged the defect and we proceeded by modifying the WSDL and using it in our integration. In the later releases this issue is fixed now.
