JNI is the standard way to call C/C++ runtime code from Java.
you find the spec under

I am embarassed to ask this question but I am very new to the using java.exe.
Does anyone know of a document that outlines specificaly how to use java.exe. I have compressed my program into a jar file and am trying to run it from it's own directory. Whenever I try to run anything in the command promt I recieve this message:
Exception in thread "main" java.lang.NoClassDefFoundError:
What does this mean? How should I set up the files /class path to fix this problem ?Go to the New to Java forum and click on the FAQ. I think "setting up your classpath" is approximately number 1 on the list there.

Thanks you very much.It is unclear where you are having a problem. Is your issue at runtime (when the form runs in the browser) or when working in the Builder on the form?
Also be aware that you will need to sign your jar and include some new manifest entries. Refer to the Java 7u51 documentation and blogs that discuss the changes.

JNI - how to use java access function in TypeLibrary( .tlb file) HELP ME PL
Hey All
I got one project which can be done by calling up functions in xxxx.tlb
(window type library) file, that is no problem.
How to use java to access those functions???
I know there are some classes which can be used to access function in
DLL file e.g. JAWIN.
Is the .tlb file related to one DLL file??? if so, how to locate the
DLL file through .tlb file???
Thanks a lot.
SteveUse JNI to create a link between Java class and a DLL, then you can load that DLL (or TLB) from that class.
Read the JNI Tutorials. -
Using java to call a text file
I am new to java and was wondering if there is a way of using java to call a text file on my server and use it to create a webpage using a template. Namely to click a link to a poem, and have the java automatically create a page from a text file of the poetry. I need to know if this is even possible, what I would need to look into, (IE: which software or applet to look for), and if there are any sites that anyone knows about that I could learn how to do this. currently I am having to create a page for every poem posted on my site, which takes a great deal of time, and I would like to speed the process up a bit if it is possible. Any suggestions would be greatly appreciated.
Why a text file? I don't think it is a best practice of doing that. Just use a database, keep your poem collections there, and set up a jsp page that seek the database, and then display it on another jsp page. I guess you can find similar application in the sample projects provided by JSC.

In SQLScript, how to use EXEC to call another procedure with parameters in procedure?
Hi experts,
In SQLScript, How to use EXEC to call another procedure with input and output parameters in procedure?thanks very muchHi Sagar,
thank you! I generate another procedure with an input parameter and an output parameter in a procedure. Then i need to call the generated procedure using EXEC. Here is my code:
create procedure ftest1(out sum_num bigint)
as
begin
declare fa_output bigint;
declare v_sql_drop varchar(200);
declare v_sql varchar(500);
declare cursor c_cursor1 for select num from TABLE1;
--v_sql_drop := 'drop procedure fe';
--exec v_sql_drop;
v_sql := 'create procedure fe(in i_num bigint,out o_num bigint) as begin';
v_sql := :v_sql || ' o_num := :i_num * 2 + :i_num * :i_num;';
v_sql := :v_sql || ' end';
exec v_sql;
open c_cursor1;
for c_item as c_cursor1 do
exec 'call fe(c_item.num,o_num=>fa_output)';
if sum_num is null then
sum_num := fa_output;
else
sum_num := :sum_num + fa_output;
end if;
end for;
close c_cursor1;
end;
The underline code is using exec to call the generated procedure. But this method cannot work. Any suggestion? thanks again! -
How to use Java as a Front-end app
how java application can be used as the Front-end interfaces to Forte based
applications???
To unsubscribe, email '[email protected]' with
'unsubscribe forte-users' as the body of the message.
Searchable thread archive <URL:http://pinehurst.sageit.com/listarchive/>Rajiv,
If you have Forte's WebEnterprise product, and Forte version 3.0.G.x or
later, you have the ability to export an IIOP interface for any Forte
service object. In fact, you can go one step further and generate a Java
interface that "hides" the IIOP issues from the developer. The way you do
this is to do the following:
1) From the partitioning workshop, double click on the service object you
wish to expose as an IIOP interface. This will bring up the Service Object
Properties dialog.
2) Off the Export tab, set the External Type drop down to IIOP. If IIOP is
not an available option in the drop down list then you do not have
WebEnterprise install.
3) From here you need to set up the necessary IIOP configuration parameters
(see the documentation for details on the specifics of what the parameters
control).
4) If you want to have Forte generate a JavaBean interface and the necessary
Java classes to be called by your application then make sure you select the
Java parameter at the bottom of the Configuration dialog. If IDL is
selected then Forte will generate a generic IDL interface.
5) When you make your distribution Forte will generate the Java classes for
you.
This mechanism works very well for accessing a Forte service object from a
Java application.
Good Luck!
Jeff Wille

In the current release, we do not support calling stored procedures from a
database control. You will have to write JDBC code in the JWS file to call
stored procedures.

You can use a database control to obtain a connection from any JDBC
Connection Pool configured in the config.xml file. The JDBC Connectionpool
could be connecting to any database, the database control is
independent
of
that.

hi forum...
how to use Java WebStart with EJB ? examples ?Well, for starters these are complementing, not 'cooperating', technologies. I presume, since EJB's do not - directly, at least - communicate with a web browser, that you intend for "Java WebStart" to somehow invoke an EJB?? Java WebStart is a technology for running client-side (Java) applications from the web browser - perceptively, the application resides on the server, but technically it, like an applet, is downloaded to the client and run there. Unlike an applet, however, it is not constrained by "sandbox" restrictions and does not have to be re-downloaded each time it is invoked - though the process allows for automagically updating the client-side with new versions of the application. ;) So, with this in mind, to "use Java WebStart with EJB" means little more than deploying an EJB client application with Java WebStart as the distribution channel.
thanks
