Hi Jason,

 

Basically what we are trying to achieved is a way to simple export data from
a legacy system into dhis2.  Once this system only generates excel files as
output we would like to import the generated file directly(without
modifications) to DHIS2 and have an import summary. 

 

We know that we can do it using several different approaches and we are
considering them J.

 

Regards,

Paulo Grácio

Hi Paulo,

I am not sure it would be worth it, but looks like it might work. Why can't
you just simply export CSV instead? Seems that given the structure of your
data, you could just simply use the CSV importer instead of setting up an
integration route?


Regards,

Jason

Hi all,

 

We are wondering about the best form to import in DHIS2 data from legacy
applications.

 

In chapter “26.4. Transforming data - a Java route” of the User Manual we
see that there is a way to do this integration using Java routes, but we are
having some difficulties in implementing a proof of concept.

 

In our PoC scenario we have a XLS file sent by an external application
(DataValues.xls in attach). Our idea is to create a Java route in order to
import all data values that exist in that file.

 

Following the tutorial “Customer 3: Excel via e-mail” presented in the
Apache Camel page -
<http://camel.apache.org/tutorial-business-partners.html>
http://camel.apache.org/tutorial-business-partners.html - we have been able
to transform the XLS file in a list of DataValue objects. 

 

Basically, we only had to create a XLSDataIn route and a ExcelConverterBean
(files in attach). The XLSDataIn takes an InputStream of an XLS file and
calls the ExcelConverterBean. The ExcelConverterBean iterates through the
file, and for each data value row, creates a new DataValue object and adds
that object to a list of DataValue objects.

 

Now we are having some issues because we don’t know the best way to insert
these data values in DHIS2.

 

The questions we are having are:

1.       The approach that we have used to implement our PoC is the correct
one? I mean, XLS -> List<DataValue> -> import is correct or we should use
XLS -> CSV -> import?

2.       How should we proceed, after the XLS file has been processed by the
ExcelConverterBean?

 

 

Thanks for your support,
