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 (VulCon), to convert an Excel file in GVBuffer.object field, in an XML document.
In order to add an operation excelreader-call you must perform the following operation:
- Open VulCon System section (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 (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:
- In VulCon Service section (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.
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 (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:
- 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>
<row number="0">
<col number="0">

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