Hi Lorenzo,
I don't understand why you would need a special servlet. Why not just use POST /smila/pipeline/<yourPipeline>/process and put everything you want to do in pipelets. You could even create a second pipeline that does the input creation in a pipelet, calls the actual pipeline that does the work and converts the result using another pipelet, if you need to seperate the actual processing from the conversion stuff.
Another way would be to create a RequestHandler like the org.eclipse.smila.processing.httphandler.PipelineProcessHandler that does the input creation and result conversion and calls the WorkflowProcessor service in between.
Sorry, we don't use Servlets in our daily work at all, so I don't have any good suggestions about them available.
Regards, JÃŒrgen.

Hi smilaers.
I need to use a servlet to send some input to a pipeline and then
get back its output and give it back to the requester as json
string.
More or less what searchservlet does.
The input of my pipeline depends on some data stored in object
store.
The pipeline I need to start accepts as input from the rest
interface something like
{
"field1": "value1",
"field2": {
"field21": "value21",
"field22": "value22",
"field23": "value23",
"field24":[
"value24a",
"value24b"
],
"field25":"value25"
}
}
And gives back something like
{
"field1": "value1",
"field2": {
"field21": "value21",
"field22": "value22",
"field23": "value23",
"field24":[
"value24a",
"value24b"
],
"field25":"value25"
},
"field3":
[
"value31",
"value32",
"value33"
]
}
As I said, I'd like to start that pipeline from a servlet and
retrieve the result converting it in json format as it was given
back from REST interface.
Thanks for your help
Lorenzo
