How to access data structures in C dll from java thru JNI?

We have been given API's( collection of C Functions) from some vendor.
SDK from vendor consist of:
Libpga.DLL, Libpga.h,Libpga.lib, Along with that sample program Receiver.h (i don't know its written in C or C++), I guess .C stnads for C files?
Considering that I don't know C or C++ (Except that I can understand what that program is doing) & i have experience in VB6 and Java, In order to build interface based on this API, I have two option left, Use these dll either from VB or Java.
As far as I know, calling this DLL in VB requires all the data structures & methods to be declared in VB, I guess which is not the case with Java (? I'm not sure)
I experiemnted calling these function from Java through JNI, and I successfully did by writting wrapper dll. My question is whether I have to declare all the constants & data structures defined in libpga.h file in java, in order to use them in my java program??
Any suggesstion would be greatly appreciated,

1. There are generators around that claim to generate suitable wrappers, given some dll input. I suggest you search google. Try JACE, jni, wrapper, generator, .... Also, serach back through this forum, where there have been suggestions made.
2. In general, you will need to supply wrappers, and if you want to use data from the "C side" in java, then you will need java objects that hold the data.

Executing DLLs from Java using JNI vs Runtime.exec()

I am trying to understand the best way to execute a dll using java. The dll I am testing with takes a few input parameter. If I use JNI with System.loadLibrary("dll"); what do I need to do to pass the arguements in as well? Can I just add the arguements in the java code like private int xyz = "value"; and expect that the dll will accept them or is there special definitions I have to set up in the dll to make it work?
Alternatively I was looking at using Runtime to execute the dll by using Runtime.exec("dll param1 param2",env,filePath); Does anyone know if there are drawback to doing it this way vs. using JNI or is this just as efficient? Any help would be appreciated.

You seem to be confused...
"execute a dll using java"
Unless I'm mistaken, a dll is not executable. A dll is a library of code. This code has (hopefully) some well-defined entry points (declared in a header file somewhere) which you must call in a C/C++ file. The arguments you pass to the dll will come from java through JNI.
As far as your understanding of this entire process, it is obviously confused beyond the scope of a simple reply. I recommend you read the examples and ALL of the documentation available here:
http://java.sun.com/docs/books/tutorial/native1.1/index.html
When you get the/an example running (or just set up to run) then post your code and comments here for more help.

To read a DLL from java using JNI

Hi,
I had some DLL files (VB 5.0) which are providing interfaces. Is there any chance of accessing that using java (JNI). Also is there any De - Compiler available so that I can get the source code of the DLL file.
Regards,
Hari.

Hola Hari
To make a dll loadable through JNI, the interface
inside
the dll must be implemented the JNI way. Also a COM
interface does not help.
I would reccomend a certain product to automatise the
JNI interfacing process, but that would
require that you have the sourcecode of the dll
available.
But one thing you can do is to write a wrapper that
contains the dll classes and is implemented the JNI
way.
More precisely you write an interface wrapper in c/c++
that matches the methods of the dll and does use JNI
methods. Now inside that c++ wrapper you load the dll
and forward the calls from java to c++ vice versa.
Download the demo version of CENTRO.java here:
www.ablon.de
Bye, nilsHi Nils,
Thank you for your suggestion. Im new to JNI.
That dll's are in Visual Basic. I don't have the source code of the dll file. I got the interfaces available in the dll file from a Visual Basic program which make use of the dll file(which we are talking about). As I know only the method signatures in the interfaces(dll file), I request you to kindly provide me some help to wrap it in C/C++ program.
Thanks in advance.
Regards,
Hari.

How to access Data Guard option in Oracle 10g OEM

Hi All,
I have Oracle 10g ENTERPRISE EDITION on Unix envoirement. I want to setup logical standby Database through Data Guard technology. But when I brows through OEM I do not find Link for DATA GUARD????
1) How to access Data Guard option from oracle 10g OEM.
2) Does It come with Enterprise Edition OR I have to install it separately.
Regards,
Darshan

I am managing almost everything through EM Grid Control. It is easy to setup and configure.
Anyways, if you have read the documentation on
Oracle® Data Guard Concepts and Administration and setup your environment accordingly then you should not have any problems. Atleast I can assure you that your production database will not be affected by it.
Just make sure that you follow each step and read thoroughly. If you have spare machines then you can test and record your configuration before performing it on your production db. This link will provide you with the information on DataGuard.
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14239/concepts.htm
If you think that way then you will never be able to do any new stuff since you will always fear that something might go wrong. Go ahead pal, try it on test machines and you will know that it is not that difficult.
There are real experts who help people like us in this forum and I know that they are doing a pretty good job.
All the best.

How to process data in the past based from data in the present

hello guys,
i have a problem in my labview programs. how to process data in the past based from data in the present ?
i have a formula self-organizing maps
this formula is looking for D1, D1 is neuron index that will be searched for the smallest value.and the result are D1=2 ,D2=5, D3=17 from calculating with formula .it means the smallest value is 2, "2" from weight [2 2] in file attached.
and then it will be in other formula
it mean [2 2] + 0.5 ( [1 1]-[2 2] ) = [1.5 1.5]
and the weight will be [1.5 2 2 ] in matrix
1.5 3 5
I would appreciate any input/help on solving this
thanks

Hi Ronny Hanks,
Moving your records from internal table into the database table depends upon various scenarios :-
1. If you use INSERT statement.
INSERT <database_table> FROM TABLE <internal_table>.
But in this case, you need to make sure that you don't have any duplicate entries in your internal table that violates data entry into database table, else you will get a dump.
INSERT <database_table> FROM TABLE <internal_table> ACCEPTING DUPLICATE KEYS.
In this case, you are forcefully inserting duplicate records into your database table which may lead to data redundancy in your database table.
2. If you use UPDATE statement.
UPDATE <database_table> FROM TABLE <internal_table>.
This will update the existing records in your database table from the internal table.
3. If you use MODIFY statement.
MODIFY <database_table> FROM TABLE <internal_table>.
This statement works both in combination of INSERT & UPDATE statements.
Existing records (in database table) will be eventually updated/modified and new records (not in database table currently) will be successfully inserted into the database table.
Hope this solves your problem.
Thanks & Regards.
Tarun Gambhir.

How can i pass string from C++ DLL to Java via JNI?

Hi everybody. I made a DLL with Borland C++. I must pass a string from this dll to Java via JNI.Namely i define a string variable in C++ DLL and i send this variable's value to Java via JNI.
I can pass integers but i couldnt Strings. . How can i do this? is there any sample?

Hi,
So your function should be private static native String get_text();
(It's often a good idea to make native methods private since when you change signatures you generally have to change java wrapper methods only).
I know nothing about C++ strings but I'm pretty sure that you can convert it to char*, so
do :
char* szMyString = myString.toChar*();
Then return from native with JNU_NewStringPlatform(env, szMyString)
(see my 1st answer for JNU_NewStringPlatform() description).

How to Select data using same column name from 3 remote database

Hi,
Can anyone help me on how to get data with same column names from 3 remote database and a single alias.
Ex.
SELECT *
a.name, b.status, SUM(b.qty) qantity, MAX(b.date) date_as_of
FROM
*((table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3)a,*
*(table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3)b)*
WHERE b.dept = 'finance'
AND a.position = 'admin'
AND a.latest = 'Y' AND (b.status <> 'TRM') AND b.qty > 0;
GROUP BY a.name, b.status ;
NOTE: the bold statements is just an example of what I want to do but I always gets an error beacause of ambiguous columns.
Thanks in advnce. :)

Each object must be uniquely identified. So you cannot do this:
select * from (table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3) a3 objects cannot share the same alias. Example:
SQL> select * from (dual, dual) d;
select * from (dual, dual) d
ERROR at line 1:
ORA-00907: missing right parenthesisYou need to combine the objects - using a join or union or similar. So it will need to be done as follows:
SQL> select * from (select * from dual d1, dual d2) d;
select * from (select * from dual d1, dual d2) d
ERROR at line 1:
ORA-00918: column ambiguously definedHowever, we need to have unique column names in a SQL projection - so the join of the tables need to project a unique set of columns. Thus:
SQL> select * from (select d1.dummy as dummy1, d2.dummy as dummy2 from dual d1, dual d2) d;
DUM DUM
X X
SQL> I suggest that you look closely at what scope is and how it applies in the SQL language - and ignore whether the objects referenced are local or remote as it has no impact to fundamentals of scope resolution.

Calling back c++ method in an exe (not a dll) from java?

Hi all,
I have to make an hybrid C++/java from an existing C++
application that compiled is a big single exe not a dll.
I'm running under win32.
The application consists of several windows. The hybrid
will have widows in C++ and some in java. They have the
same menu and tool bar. In the C++, there are some
callbacks called when a button is pressed. How to call
these callback from java given the fact that the JVM and
the java classes are launched by the exe file.
I know how, from C++, start JVM and call my java window.
I also know how to call a C++ method that is in a dll from
java. It's from the tutorial
http://java.sun.com/docs/books/tutorial/native1.1/index.html
But I don't know how to call a C++ method that is in in an
exe which has launch a JVM from an object running in this
JVM.
Is there somewhere an example like this?
Thanks,
Xavier.
