Error while executing procedure from the web

Question

Hi,
<p>
I am developing some procedures that I want to execute from an html form. The problem is that when I am trying to execute it in SQL Developer I got the following error:<br>
Connecting to the database oracle.<br>
ORA-06502: PL/SQL: numeric or value error<br>
ORA-06512: at "SYS.OWA_UTIL", line 325<br>
ORA-06512: at "SYS.OWA_UTIL", line 366<br>
ORA-06512: at "MMARTA.INSERTPROJECT", line 3<br>
ORA-06512: at line 10<br>
Process exited.<br>
</p>
<p>
The procedure is the following:<br>
create or replace <br>
procedure insertproject(jnum j.j#%type, jname j.jname%type, city j.city%type) as <br>
begin <br>
owa_util.mime_header('text/plain');<br>
if jpak.insertj(jnum,jname,city)<0 then<br>
htp.print('The jnum already exists in the database!');<br>
else <br>
htp.print('Insert successfull!');<br>
end if;<br>
end;<br>
<br>
and the function has the following code:
<br>
function insertj(jnum j.j#%type, jname j.jname%type, city j.city%type)<br>
return number is<br>
x number;<br>
begin<br>
Select count(*) into x From J<br>
Where J#=jnum;<br>
if x=0 then<br>
insert into J values(jnum,jname,city);<br>
commit;<br>
return 0;<br>
end if;<br>
return -1;<br>
END insertj;<br>
</p>
<p>
Does anyone have any idea why I get this error?
</p>
<p>
Thanks!

Hi,
<p>
The function has the following parameters:<br>
function insertj(jnum j.j#%type, jname j.jname%type, city j.city%type)<br>
where j# is varchar2(5), jname is varchar2(35) and city is varchar2(35)<br>.
I was trying to insert the following values:<br>
j#:='J11', jname:='JobName' and city:='Paris'.<br>
</p>
<p>
The procedure just calls this function with the same parameters. It is very strange because it is hard to see what the problem is. The line 10 is return 0 in the function where I believe the error comes from. It starts in the procedure and then goes in the function body, if I am interpreting this right.
</p>
<p>
Any idea?

Thanks!
