How to call C functions from native functions?

Hi, I want to call a C function from a JNICALL?
i wrote somthin like this:
#include "ParamInput1.h"
#include <jni.h>
#include <stdio.h>
#include "testPhase1.h"
JNIEXPORT void JNICALL
Java_ParamInput1_phase1(JNIEnv *env,
               jobject obj,
               jdouble tSim,
               jdouble tSup,
               jdouble iSim)
double threshSim = tSim;
double threshSup = tSup;
double itemSim = iSim;
/* call test Phase1 to execute the function*/
testPhase1(threshSim, threshSup, itemSim);
return;
And I always get "undefined symbol: testPhase1__Fddd" error!
what is the problem here? thanks alot!

Basically - you are already are compiling a c file. Replace that c file with all the c files.
Specifically it depends on the OS, compiler and how you are compiling
For windows add it the project or compile each file and then add the object fill to the link line.
For unix add the other c files in to the compile line the same place you have the current C file.

How to call oracle function from ejb3

i'm trying to call an oracle query-function from ejb3.
The oracle function:
create or replace FUNCTION getSecThreadCount(secId in NUMBER,avai in NUMBER)
RETURN SYS_REFCURSOR is cur SYS_REFCURSOR;
m_sql VARCHAR2(250);
BEGIN
m_sql:='select count(thrId) from thread where secId='|| secid||'
and thrAvai='|| avai;
open cur for m_sql;
return cur;
END;
I'v tried several ways to call it,but all failed:
1. the calling code:
public Object getSectionThreadCount(int secId,int avai){
          Query query=manager.createNativeQuery("{call getSecThreadCount(?,?) }");
          query.setParameter(1, secId);
          query.setParameter(2, avai);
          return query.getSingleResult();
but i got the exception:

2. the calling code:
@SqlResultSetMapping(name = "getSecThreadCount_Mapping")
@NamedNativeQuery(name = "getSecThreadCount",
query = "{?=call getSecThreadCount(:secId,:avai)}",
resultSetMapping = "getSecThreadCount_Mapping",

public Object getSectionThreadCount(int secId,int avai){
          Query query=manager.createNamedQuery("getSecThreadCount");
          query.setParameter("secId", secId);
          query.setParameter("avai", avai);
          return query.getSingleResult();
but i run into the exception:

By the way, i have successfully called the function from hibernate. And i use oracle 11g, JBoss5 RC1.
Could anyone tell me how to call the function from EJB3?
Thanks.

}Basically you just ignore the refcursor outbound parameter.
This is a stored function, have yet to try outbound refcursor parameters in stored procedures...

How to call a function from asp

Hi!, I'd like to know how to call a function from an asp page. I've written:
set rs = server.createobject("Adodb.recordset")
rs.open "call dbo.sf_Obt_Des_Producto ('0000161')",Conn
if err.description <> "" then
response.write ("No se pudo! :(")
else
response.write ("rs: " & rs(0))
end if
rs.close
set rs = nothing
but there is an error:
ORA-06576: not a valid function or procedure name
Please is very urgent!!!
Thanks.
Angie.

You need to use the syntax "{call <procedure_name>}".
The {call } syntax tells the OLE DB provider that it needs to translate the call into whatever the database's procedure calling syntax is. This means that even though different databases have different syntax for calling stored procedures, your OLE DB code can be run against any of them without changing.

How to call java function in javascript?
Thanks,

You can't since Java is running on the server and javascript is running in the browser long after the Java side of things has finished executing. Assuming you're not talking about an applet here.
But you can make calls back to the server through Ajax. All you need is something like a servlet on the receiving end which you can invoke through Ajax; from that point you can execute any Java code you want.

How to call stored procedure from Pro*C

How to call stored procedure from Pro*C ?
my system spec is SuSE Linux 9.1, gcc version : 3.3.3, oracle : 10g
my Pro*C code is the following..
EXEC SQL EXECUTE
begin
test_procedure();
end;
END-EXEC;
the test_procedure() has a simple update statement. and it works well in SQL Plus consol. but in Pro*C, there is a precompile error.
will anybody help me what is the problem ??

I'm in the process of moving C files (with embedded SQL, .PC files) from Unix to Linux. One program I was trying to compile had this piece of code that called an Oracle function (a standalone), which compiled on Unix, but gives errors on Linux:
EXEC SQL EXECUTE
BEGIN
:r_stat := TESTSPEC.WEATHER_CHECK();
END;
END-EXEC;
A call similar to this is in another .PC file which compiled on Linux with no problem. Here is what the ".lis" file had:
