Definition
Many IT applications in their business process needs to read an Excel file. GreenVulcano 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 stream of Excel file and returns in output an XML structure. At the output of Gvvcl-excelreader plug-in is possible to apply a changeGvBuffer operation (with ognl script or an xsl stylesheet) to retrieve all interested data.
GreenVulcano ESB provides two tools, GVConsole and Vulcon, to configure all GreenVulcano supported plug-ins in GV services.
Vulcon Configuration
excelreader-call is the operation that must be configured into Vulcon system section, to convert a 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
- 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
- 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 services section select the services that you want modify or you can create a new Services
- On flow tag, you clicks the right mouse button and select "insert before"
- On the list of GreenVulcano node select GvOperationNode
- On the template that appear, you must select from drop down list, input fiel, 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 GvConsole
At this point you have use excelreader-call operation in a GreenVulcano service.
GVconsole Configuration
excelreader-call is the operation that must be configured into GvConsole system section, to convert a Excel file, in GVBuffer.object field, in a XML document.
To add an operation excelreader-call user must perform the following operation:
- You open GVconsole system section
- You clicks button "insert before" and select label --> excelreader-call
- In layout you fill in field name, i.e. the name of operation that will be used in Vulcon service section
- Other fields class, onlyData and type will be ignored
At this point, you have configured an operation of type excelreader-call in a GvConsole.
To use an excelreader-call in a GreenVulcano ESB service, you need to perfom the following steps:
- In GvConsole services section select the services that you want modify or you can create a new Services
- On flow tag, you clicks the add operation node button and select "insert before"
- On the list of GreenVulcano node select GvOperationNode
- On the template that appear, you must 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 GvConsole
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">
<data><![CDATA[SOURCE_RNCID]]></data>
</col>
<col number="1">

<col number="2">

</row>
<row number="2">
<col number="0">
<data><![CDATA[23]]></data>
</col>
<col number="1">
<data><![CDATA[711]]></data>
</col>
<col number="2">

<col number="3">

</col>
<col number="4">
<data><![CDATA[1]]></data>

<col number="6">

</sheet>
</workbook>
With a ChangeGVBuffer node is possible parsing XML and retrieve any tag and value.
