face="Times New Roman"><span style='font-size:12.0pt'>Hi All<br>
<br>
If i am correct !! all the spatial queries are done on the geometry objects
..in the table ..<br>
<br>
For example:- <br>
I have a table ..which has a geometry column which of type say POLYGON ...say
bounds<br>
I want to write a spatial query .. <br>
<br>
select * from table where intersects (GEOMFROMTEXT('POINT(0 0)'),bounds);<br>
<br>
but if some one is using Hibernate with Postgis ... I have to run this as a
native sql query ..<br>
BUT has anyone worked on Postgis ..Geometry Java CLass ..so that ..i can run a
createria query <br>
like <br>
<br>
"from Tiles t where t.bounds.intersects('POINT(0 0)')";<br>
<br>
if someone thinks it is worthwhile to work on .. i would like to work on it ..<br>
<br>
thanx ...<br>
<br>

<p class=MsoNormal style='margin-bottom:12.0pt'><font size=2 color=navy
face=Arial><span style='font-size:10.0pt;font-family:Arial;color:navy'>This would
be useful as an object query, so EJB-QL, or HQL. I ran a demo project from
Jan earlier this week with the hibernate postgis driver (so dropping all my
EJB3 code) and it works fine in a hibernate/spring environment as well as
JBoss. I notice that the query parser for hibernate 3 is different to
2.1, I think this may be a major piece of work – let me know if I can
help.<o:p></o:p></span></font></p>
