two things:
(a) in sample (2) above, the parameter should be :
"params":
{"valorId": "5"}
because "valorId" is the input of type String to your EMML.
(b) second part (second JUMP script where you are not getting the value) seem to be a bug. Looking into it.

btw, the correct JUMP scripts are :
{
"version": "1.1",
"sid": "SB1",
"svcVersion": "0.1",
"oid": "invoke",
"header": {
"resultFormat": "xml",
"sessionbinding": ["@session.ValorId=/prueba/ValorInput"]
},
"params":
{"valorId": "5"}
}
{
"version": "1.1",
"sid": "SB2",
"svcVersion": "0.1",
"oid": "invoke",
"header": {
"resultFormat": "xml",
},
"params":
{"prueba": "$session/ValorId"}
}
see *parameter* section in both JUMP requests. In both cases (from your EMML), the inputs are simple/string types. So, you can pass the values using either map (named parameters) or array (indexed parameters). In your sample scripts, both methods were combined i.e. map inside array.

Hi everybody:
Im trying to use session parameters to map Presto Parameters to Service Parameters with PC4JS but I can't get it working.
Here is my example:
1. First I created a mashup with a simple output and I published it as a service, the mashup:
<mashup xmlns="http://www.jackbe.com/2008-03-01/EMMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:macro="http://www.jackbe.com/2008-03-01/EMMLMacro"
xsi:schemaLocation="http://www.jackbe.com/2008-03-01/EMMLSchema ../src/schemas/EMMLSpec.xsd"
name="prueba_persistencia_parametros_sesion12">
<operation name="invoke">
<output name="result" type="document" />
<variables>
<variable name="ValorInput" type="string"/>
</variables>
<input name="valorId" type="string"/>
<assign fromexpr="concat($valorId,' Este era el valor inicial')" outputvariable="ValorInput"/>
<constructor outputvariable="result">
<prueba>
<ValorInput>{$ValorInput}</ValorInput>
</prueba>
</constructor>
</operation>
</mashup>
2. I did the following test in JUMP:
{
"version": "1.1",
"sid": "prueba_persistencia_parametros_sesion11",
"svcVersion": "0.1",
"oid": "invoke",
"header": {
"resultFormat": "xml",
"sessionbinding": ["@session.ValorId=/prueba/ValorInput"]
},
"params": [
{valorId: "5"}
]
}
With this I got the value without problems.
3. I created another simple mashup with a single input:
<mashup xmlns="http://www.jackbe.com/2008-03-01/EMMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:macro="http://www.jackbe.com/2008-03-01/EMMLMacro"
xsi:schemaLocation="http://www.jackbe.com/2008-03-01/EMMLSchema ../src/schemas/EMMLSpec.xsd"
name="Service2">
<operation name="invoke">
<output name="result" type="document" />
<input name="prueba" type="string" default="1202"/>
<constructor outputvariable="result">
<prueba>
<ValorInput>{$prueba}</ValorInput>
</prueba>
</constructor>
</operation>
</mashup>
4. The test in JUMP:
{
"version": "1.1",
"sid": "Service2",
"svcVersion": "0.1",
"oid": "invoke",
"header": {
"resultFormat": "xml",
},
"params": [
{prueba: "$session/ValorId"}
]
}
With this test I passed the session’s value to the mashup’s input, but it seems the value is not the one I got with
the session binding.
If I declare a session variable in the mashup:
<variables>
<variable name="session.ValorS" type="string"/>
<variable name="ValorInput" type="string"/>
</variables>
I get the following output:
Executing the Script in Run Mode...
2009-07-17 17:50:38,262 ERROR [com.jackbe.jbp.sas.common.JBPStateManager] - <ConfigMgr: setSessionAttribute : Cannot find HttpServletRequest object Unable to store session attribute : ValorS>
