Error consuming Web Service via Systools.HTTPPOSTCLOB

Hi all

I'm try to consume a web service with this statement:



SELECT *

FROM JSON_TABLE(

Systools.HTTPPOSTCLOB(

'https://wsurl/zzz/changexx',

'<httpHeader> <header name="content-type"
value="application/json" /> </httpHeader> ' ,




'{"user":"MYUSER","psw":"mypass":"123","order_id":"6","sts":"A","sub":"X"}')
,

'$'

COLUMNS(

"status" VARCHAR(30) PATH 'lax $.status' DEFAULT '' ON
EMPTY,

"err" VARCHAR(1024) PATH 'lax $.err' DEFAULT '' ON EMPTY

)

) AS x;



but i receive this error:



Message: [SQL4302] The Java stored procedure or user-defined function
SYSTOOLS.HTTPPOSTCLOB and the specific name HTTPP00013 aborted with an error
"com.ibm.jsse2.util.h: PKIX path building failed:

I'm running V/R2



Which could be the problem ?



Thanks in advance
