Definition

Many IT applications, within their business process, need to read an Excel file. Gvvcl-excelreader plug-in helps IT organizations integrating applications that use Excel format to execute their business. Gvvcl-excelreader plug-in is compatible with all Excel formats up to version 2003, and it is very simple to configure. It receives in input a binary stream containing the Excel file, and returns in output a corresponding XML structure. At the output of Gvvcl-excelreader plug-in is possible to apply a ChangeGvBufferNode operation (with OGNL script or an XSL transformation) to retrieve all interested data.

GreenVulcano® ESB provides two different tools, GV Console and VulCon, to configure all supported plug-ins in GV services.

VulCon Configuration

excelreader-call is the operation that must be configured into VulCon [[System section (Template:VulCon)]], to convert an Excel file in GVBuffer.object field, in an XML document.

VulCon® system excel-reader configuration

In order to add an operation excelreader-call you must perform the following operation:

  • Open VulCon [[System section (Template:VulCon)]]
  • Then click right mouse button and select "insert before" label --> excelreader-call
  • In layout fill in field name, i.e. the name of operation that will be used in VulCon [[Service section (Template:VulCon)]]
  • Other fields class, onlyData and type will be ignored

At this point, you have configured an operation of type excelreader-call.

To use an excelreader-call in a GreenVulcano® ESB service, you need to perfom the following steps:

File:Service-GVvcl-excel.png
Vulcon service excel-reader configuration
  • In VulCon [[Service section (Template:VulCon)]] select the services that you want modify or you can create a new Services
  • On flow tag, click the right mouse button and select "insert before"
  • On the list of GreenVulcano node select GvOperationNode
  • On the template that appears, select from drop down list, input field, next-node-id and as operation-name the operation configured in the system. Fill in fields id and output.
  • Use VulCon function Export in compressed file
  • Reload configuration from GV Console

At this point you have inserted an excelreader-call operation within a GreenVulcano® ESB service.

GV Console Configuration

excelreader-call is the operation that must be configured into GV Console System section (GV Console), to convert an Excel file in GVBuffer.object field, in a XML document.

File:CreateOperationExcelReaderGVConsole.png
Gv Console system excel-reader configuration

To add an operation excelreader-call you must perform the following operation:

  • Open GV Console System section (GV Console)
  • Click button "insert before" and select label --> excelreader-call
  • In layout fill in field name, i.e. the name of operation that will be used in VulCon [[Service section (Template:VulCon)]]
  • Other fields class, onlyData and type will be ignored

At this point, you have configured an operation of type excelreader-call in GV Console.

To use an excelreader-call in a GreenVulcano® ESB service, you need to perfom the following steps:

File:Service-GVvcl-excelGvConsole.png
GV Console service excel-reader configuration
  • In GV Console Service section (GV Console) select the services that you want to modify or, alternatively, you can create a new Services
  • On flow tag, click the add operation node button and select "insert before"
  • On the list of GreenVulcano node select GvOperationNode
  • On the template that appear, select from drop down list, input field, next-node-id and as operation-name the operation configured in the system. Fill in fields id and output.
  • Click save button and terminate editing
  • Reload configuration from GV Console

At this point you have configured a service with an excelreader operation.

Example

This example shows an XML document generated by a simple Excel sheet (without cols and rows grouping). Given an Excel sheet with the following structure:

ID1 ID2 ID3 ID4 ID5 ID6 ID7
23 23232 23 23333 1 2 3
24 24444 23 23332 1 2 3

excelreader-call generates the following XML: 

<?xml version="1.0" encoding="UTF-8"?>
<workbook>
    <sheet number="0">
        <name><![CDATA[Foglio1]]></name>

With a ChangeGvBufferNode is possible parsing XML and retrieve any tag and value.
