[mapserver-users] msPostGISLayerWhichShapes() Error : java library set wrong query

[Francesco Martinelli]

Hi all,
I have a java program calling the method draw() of class
edu.umn.gis.mapscript.mapObj
after I compiled mapserver 7.6.4 on Ubuntu 20.04

The result produce the following error:
*java.lang.UnknownError: msDrawMap():* Image handling error. Failed to draw
layer named 'MyLayer'.;*msPostGISLayerWhichShapes(): Query error*. Error
executing query. Check server logs
edu.umn.gis.mapscript.mapscriptJNI.mapObj_draw(Native Method)
edu.umn.gis.mapscript.mapObj.draw(mapObj.java:397)

In mapfile I set the parameters:
*CONFIG* "MS_ERRORFILE" "myfile"
*DEBUG* 6
...
*LAYER*
    *CONNECTIONTYPE* postgis
    *DATA* "the_geom FROM (SELECT * FROM classi_comuni WHERE tipo_area = 2
ORDER BY tipo_area DESC) AS confini USING UNIQUE gid"
    *CLASSITEM* "my_column"
...

and in the error file I got the following message:
[Wed Jan 26 17:14:19 2022].558530 msDrawMap(): rendering using outputformat
named png24 (AGG/PNG).
[Wed Jan 26 17:14:19 2022].569532 msPostGISLayerWhichShapes(): Error

HINT:  "POLYGON((774076,75" <-- parse error at position 18 within geometry
) executing query: select "my_column"::text,ST_AsBinary(("the_geom"),'NDR')
as geom,"gid"::text from (SELECT * FROM classi_comuni WHERE tipo_area = 2
ORDER BY tipo_area DESC) AS confini where "the_geom" &&
ST_GeomFromText('*POLYGON((774076,75

4875124,5,774076,75 4875124,5))*',find_srid('','classi_comuni','the_geom'))
[Wed Jan 26 17:14:19 2022].569545 msPostGISLayerWhichShapes(): Query error.
Error executing query. Check server logs
[Wed Jan 26 17:14:19 2022].569605 msDrawMap(): Image handling error. Failed
to draw layer named 'MyLayer'.

I checked the error is caused by decimal separators being commas instead of
dots.
As far as I understand the correct query would be (in *red* the changes):
select "my_column"::text,ST_AsBinary(("the_geom"),'NDR') as
geom,"gid"::text from (SELECT * FROM classi_comuni WHERE tipo_area = 2
ORDER BY tipo_area DESC) AS confini where "the_geom" &&
ST_GeomFromText('*POLYGON((774076.75
4875124.5,774076.75 5115124.5,1014076.75 5115124.5,1014076.75
4875124.5,774076.75 4875124.5*))',find_srid('','classi_comuni','the_geom'))


I think I should set something during the compilation of java mapserver
library.
Please can someone drive me on how to solve it?


Thank you,
Francesco
