Parameters sent from Uniface to Web service not seen

Hi Tatiana

with the activate you have put the name of the entity in quotes.

So your parameter is just the string "RETRIEVEREQUEST.HTTP_WS_TEST", not the expected entity.

Remove the quotes and give it another try.

With -150 there should be some info of the actual error in the message frame.

There isn't when I get the same error. And the entity name is fine in Quotes, out of quotes it tries to take it as a variable I think.

.. but isn't it a variable if we assign values to it in our component (w/o storing) before calling the webservice ?

for me it looks more like a "struct" type of parameter converted into a uniface entity.

I agree it's an entity, but when I have tried to use the entity name without quotes in this type of call, the compiler (and runtime) treat it as a (non-existent) variable, in which they expect to find the entity name stored.

Except when using it to specify a field, I almost always find that "ENTITYNAME" will work much better than ENTITYNAME, virtually everything expects ENTITYNAME without quotes to be a variable defined in the local proc or a fieldname.

Hi Iain,

looks like there is a gab between theory an the real life.

I have not so much experience how to make it happen under real-world circumstances and sometimes it's a big surprise what you have to do to make it happen.

Thanks everyone for the input.

I tried removing the quotes from the entity name, but I got a compiling error and same result -150.

I am told via local CPWR support that there is an issue with unescaped data (whatever this is!), and Amsterdam is looking into it. Meanwhile, we had no issue accessing another web service using just strings. This servise did not require parms sent as occurrence.

Will keep you posted.

hi tatjana

"unescaped" is just when you have some special characters in a normal string.

Example from uniface: if you want to place a quote in a string, you have to escape it with "%%" so your assignment will become

my_string = "a string with a quote: %%" in it"

if you do not escape the quote in the string, you will get a compile error

In XML for example a > has to be ampersand letter g letter t. (I tried to type it here but it automatically converted to > again)

... plus a semicolon at the end.

The general structure is an amperand to start the sequence and a semicolon terminating it.

Hi,

my first thought was that you shouldn't use "RETRIEVE" as the operation name for the web-service. But I suppose it's ok as no one has said anything about it.

I have just determined why MY web services activate was getting an error 150.

I have paths set up to a urouter, and uniface was trying to run the service on the urouter, I had to include the service in the asn file [SERVICES_EXEC] part with
SERVICE=SERVICE
to get it to run 'local'.
