TestFileAttachment

Description

TestFileAttachment description

This example shows how use GreenVulcano^® ESB to send an email containing attachments.

TestFileAttachment services executes the following operations:

• Reads a file from a directory of input (in this case TestAttach/input)
• Sends an email with this file as attachment
• Moves sent file to another directory (we choose TestAttach/sent)

VulCon Configuration

To configure TestFileAttachment service follow these steps:

1. Define the System, Channel and Operations required
2. Define the Services
3. Implement the flows.

Defining System, Channel and Operations

To define a System, go to VulCon core view and, into Systems element, insert the System GVESB if it is not already present. Inside of it create the Channel TEST_CHANNEL_FILE in which the following operations will be configured:

• filemanager-call

Attribute/Subelement	Value
name	ScanAttachments FileCommands: FileSearchCommand filePattern=".*" returnFullPath="true" sourcePath="${{gv.app.home}}/TEST/TESTFS/TestAttach/input"

• filemanager-call

Attribute/Subelement	Value
name	MoveAttachments FileCommands: FileMoveCommand: filePattern=".*" sourcePath="${{gv.app.home}}/TEST/TESTFS/TestAttach/input" targetPath="${{gv.app.home}}/TEST/TESTFS/TestAttach/sent"

• smtp-call

Attribute	Value
jndi-name	gvesb.mailServer
name	SendEmail
mail-message	content-type="text-html" high-priority="true" sender-display-name="GV ESB" subject="Test send attachments" destinations: to: mail-address: address="gv2@gv.com" message-body: gvBuffer-dump="false" message-text: ${'Attachment file list:\n'+property['GV_SMTP_ATTACHMENTS']}

Flow implementation

TestFileAttachment flow

To implement the TestFileAttachment service Flow design it as shown in the picture:

The service searchs the files present in a directory, sends it as attachment and moves it into another directory

The following table shows the nodes and attributes to be defined for each Flow node:

Attribute/Subelement	Value
first-node	Prepare
Conditions/GVBufferCondition	condition="FilesFound" type="condition" Property: name="GVFM_FOUND_FILES_NUM" operator="greater" type="gvbuffer-field" value="0" value-type="integer"
GVOperationNode	dump-in-out="false" id="list_files" id-system="GVESB" input="input" next-node-id="check_files" op-type="call" operation-name="ScanAttachments" output="files"
GVNodeCheck	default-id="end-nofiles" id="check_files" input="files" on-exception-id="end" GVRouting: condition="FilesFound" next-node-id="prepare"
ChangeGVBufferNode	dump-in-out="true" id="prepare" input="files" next-node-id="send_email" output="files" ChangeGVBuffer: clear-data="false" OGNLScript: property['GV_SMTP_ATTACHMENTS'] = property['GVFM_FOUND_FILES_LIST']'
GVOperationNode	dump-in-out="false" id="send_email" id-system="GVESB" input="files" next-node-id="move_files" operation-name="SendEmail" output="files"
GVOperationNode	dump-in-out="false" id="move_files" id-system="GVESB" input="files" next-node-id="end" operation-name="MoveAttachments" output="files"
GVEndNode	end-business-process="yes" id="end-nofiles" output="files"
GVEndNode	end-business-process="yes" id="end" output="files"
