Error in calling 'C' Program from Java

Hi,
We developed a 'C' Program and during compilation, we got a couple of Incompatible Prototype warnings. Then we made a Jni call to 'C' program from Java Program. The program returned a "Unsatisfied Link Error - unreference Symbol not found" error.
Does Jni call fails owing to warnings by compiler?

Request your assistance as this a urgent issue.

Did you try running your C program through g++? It sounds like something is broken, but GCC often will allow you to compile anyways.

Calling external programs from Java?

Hi All,
Is there a way of calling external applications from Java without using Runtime.exec(). That method seems quite messy when you are dealing with streaming data from an input file to an output file. Basically what I'm asking is there a way to run a command the same way you would type it in a command shell?
Thanks

Ok, I've an external application that I want to be called inside a Java GUI. It has several input arguements, which the format looks something like:
programname inputfile > outputfile
Simple enough.

Works fine from a shell command line. From what I understand, this won't work using Runtime.exec() because that method will just start the application. Works fine from Runtime.exec(). Since you are'>' to write stdout to a file you need to us a shell to execute the command.
String[] command = {"sh", "-c","programname inputfile > outputfile"};
Process process = runtime.exec(command);
You need to read, digest and implement the recommendations given in http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html .
File input and output from the application has to be taken care of programatically (java.io stuff). Fine if you've only one input and output. But if you have several input files and hundreds of output files, where does this leave you. It would be much easier if you could pass a string command to the shell directly as if you typed it in the command line yoursel!

Calling RPG program from Java

Hi All,
I'm somwhat new to Java (coming from an AS400 background) and I'm stuck with what I think is a fairly simple problem. But I've been looking at this for so long, I'm probably missing something really simple and I hope someone can help me with this.
I've created a bean that needs to call an RPG program on the AS400. I've looked at code throughout this site to compare and it looks the same. My problem is I'm getting an error when I try to run it.
"com.ibm.db2.jdbc.app.DB2SQLException2: [IBM][JDBC Driver][14012] The index for the parameter is not valid."
Here's my code:
CallableStatement stpCall ;
String sql = "CALL LIB.CHECKLOGIN ( ?, ?, ? )" ;
try {
Connection connection = null;
connection = ivDataSource.getConnection();
stpCall = connection.prepareCall( sql ) ;
stpCall.setString( 1, ivUserID ) ;
stpCall.setString( 2, ivPassword ) ;
stpCall.registerOutParameter( 3, Types.INTEGER ) ;
stpCall.execute() ;
} catch (Exception e) {
System.out.println(e);
I've tried it a couple different ways and still get the same error. So if anybody can let me know what I'm missing or what I'm doing wrong I would greatly appreciate it. Thanks.

Thanks jedilowe.

stpCall.execute() ;
ivError = stpCall.getString(3) ;
} catch (Exception e) {
e.printStackTrace();
I'm looking through the stderr log now. Most of if looks like a foreign language, but do you have an idea of what to look for? Anything specific? Here's a few lines from the log:

Calling windows programs from Java

Hello,
I need to find how to call and pass parameters to windows programs. Specifically I need to call MS Sql server, there is call that I can do from command promt but I would like to give it some GUI interface and ease of use so I could pass some parameters to the program and execute it.
Thanks.

Hi thanks for all replies !
Ok let me explain more about my problem.
I have a SQL server which runs on MS machine and there is thousands of stored procs that my be recreated once in a while from a directorys. So we have scripts which we have to manually update every time new stored proc is written and run against the server to update all of them at one batch.
Now I often have to browse to this directory from linux machine and I basically already written the Java program that gets all the files in the directory and passes them via JDBC to the server.
Thats where the problem starts, when you calling and passing sp to sql without any header seting the jdbc is fine but when you pass sp with such settings for instanse as "SET QUOTED_IDENTIFIER and SET ANSI_NULLS OFF" in the header of stored proc then SQL server complains and fires exceptions on me.
So this is my problem.

u can solve this problem with lexical parameter.
create a user parameter and use it as lexcical parameter.
create a ur on form with form builder instead of report default parameter form and run reprport with parameters.
here is an exmple that i used.
if :Month is not null and :year is not null and :sjnl_no is not null then
declare
plist paramlist;
begin
plist := get_parameter_list ('list_1');
if not id_null(plist) then
destroy_parameter_list (plist);
end if;
plist := create_parameter_list ('list_1');
add_parameter (plist, 'P_where', text_parameter,'and (doc_no='||:SJNL_NO||')and to_char(doc_date,''MON-YYYY'')='''||:MONTH||'-'||:Year||'''');
add_parameter (plist, 'DESTYPE', text_parameter,:des_type);
run_product(REPORTS,'sale_journal', SYNCHRONOUS, RUNTIME, FILESYSTEM, plist);
exit_form;
end;
else
