How to access C/C++ functions in Java using existing .dll library

Hi JNI Guru's,
I am having well written API in C/C++.This C/C++ files are made into *.dll files.The api are working fine.
I wan't access the C/C++ api functions in Java., just using System.LoadLibrary("*.dll").Is it possible.I kindly request you to suggest some examples and how to do this.
Its Urgent !.
Thanks and Regards,
V K LAL

In general you cannot simply access dlls that have already been written. The DLLs called using JNI must conform to JNI calling standards.
This means you will probably have to write one or more "wrapper" dlls which a) provide the correct JNI interface, and b) call the existing dlls.
There are some programs around that claim to be able to generate such wrappers. Try a google search for "wrapper", "jni", "generate".
The JNI tutorial covers creating wrappers.

How to access the Text Frame, when we use scrollable frame,

Hi Friends,
How to access the Text Frame, when we use scrollable frame,
Thank you,
[ Nav ]

That's the same question:
how can I access something (a page item) on a page…
Answer: you need something unique in that object you can get a handle on.
Or you use the selection a user of your script is doing and work with that selection…
A "scrollable frame" is nothing special. What it makes it a "scrollable frame" is the DPS software.
So you have to look for attached labels on the object, that identify the object for the PDS plug-in "Overlay Creator" as a "scrollable frame". That's possible with the "extractLabel("KeyString")" function. But you need to know the appropriate key-string in advance.
In another of your thread in the DPS forum, I basically answered the question how to obtain those key-strings.
When knowing the key-string you could loop through all your page items (you can skip all text frames) in the allPageItems-collection, to identify the "scrollable frame" by extracting the right label.
If you have more than one "scollable frames" you need a second unique identifier for the particular object.
That could be nearly any property.
Keep in mind, there is no "scrollableFrames" collection in the DOM !

Thanks in advance for the answer.

u r calling lightParse method without passing the expected "String" argument. There must not be an overloaded method for lightParse without any arguments.
So u should use this:
lightParse(some string here);
Hope this explains.

How to access SAP database tables with Java (Jco)

Hi!
I need to develop a Java Client for SAP with access to the SAP database. Is there a way to do this directly in Java (the db access) or do I have to use some ABAP logic in between to get the information to the java client? If so, are there any existing ABAP functions to read AND write db tables? Or do I have to create my own wrappers for each table I need to read and write?
Thanks,

Guidance required: How to access global panel/file handles from within a dll?

Hi again,
I have been tasked with trying to separate an application into a modular form, basically I will have a main application which will be a generic GUI which must be associated with a DLL that contains test sequences. Currently these test sequences make calls to the various panel controls to display the test information, this currently works great. The problem that I am having is trying to understand code that is compiled to create a DLL is made aware of, what is essentially, global constants that are defined in my main application.
The purpose of this structure is that we will have a generic GUI for multiple products tests, with each DLL representing a different products test sequence, each DLL will be built using the same framework with the generic GUI in mind.
I guess essentially what I am looking for is to call RunUserInterface() from main.exe and control the GUI from tests.dll. Is this at all possible, or should I be using a different approach?
It would be much appreciated if someone could give me some pointers.
Thanks very much

Well, in my opinion for such a software design, DLL modules should not directly modify the main GUI.
The main.exe should be responsible from its GUI, so that in case of a GUI modification you should not be have to modify all DLLs.
Also, in this case, there is no problem of accessing global handles, etc.
Instead, you should send "messages" to the main.exe from the test DLLs and the GUI should know what to do with each message.
For messaging between such applications I personally use the DDE library. I find it simple to use.
Your main.exe can setup a DDE server and the test DLLs can attach to it as a client.
Each DLL can send its "steps" to the GUI and the GUI can display them and command the DLL to run each step upon user's selection.
I have seen menchar's posts regarding "shared memory" usage for such purposes.
There might be other options, too.
It is your decision to make.
Hope this helps,

How to setup iTunes on a PC to use existing music

My partner has a PC laptop provided by her work. She wishes to use iTunes with it but store her music on an external drive. We already have her previous iTunes library on an external drive, but we don't have the iTunes Library.itl file, etc.
My question is: how can my partner setup iTunes on her work laptop to use her previous iTunes library/music on her external drive?
My concerns are:
Changing iTunes preferences and telling it the iTunes library is in a folder on the external drive does nothing. iTunes just ignores the music in this folder because the iTunes Library.itl file, etc on the c:/ drive don't know anything about it. (It's a new installation of iTunes.)
I've already tried importing the previous iTunes library. We chose the File > Library > Add folder menu (if I've got that right) but it only imported about 500 songs from the various folders. This tells to me that iTunes for PC is buggy - it cannot scan many folders, either wide or deep, to find songs in subfolders.
Windows may allocate a different drive letter each time the external drive is attached. For example, if my partner is not VPN'd into her work network then Windows may allocate a "lower" drive letter for the exernal drive than if she is logged into her work VPN.
I'd rather not have to reimport all the songs.
We have a copy of all her former iTunes library music on both an iPod Classic and an iPhone 4. Is it possible and better to import the music from one of these devices?
Many thanks!

Although you can set up iTunes with the library on the C: drive and the media folder elsewhere there are, as you have found out, pitfalls with that approach. Ideally you would have access to the "old" library, complete with the .itl file and simply copy this onto the external drive. Failing that then I would recommend you build the library at X:\iTunes where X: is the current drive letter assigned to the external drive. Your media folder should be X:\iTunes\iTunes Media. If you deliberately assign a specific letter for your drive, perhaps M: for Media, then it should always be given that letter.
With your library redirected to the external drive, not just the media folder, if you do attempt to start iTunes with the drive not present iTunes will complain it can't find the library. Simply close iTunes, connect the drive and start iTunes again. All will be OK, no links will get broken, and you won't have to correct the media folder location.
Regarding specific points
1. Note, changing the media folder location only tells iTunes where to put new files that you rip, consolidate, download etc. It is not a command to scan that folder and add or replace the current content with what is found there.
2. When using the File > Library > Add folder to library method iTunes will ignore any files for which it has insufficient security permissions. Check these and ensure your user account and system have full access to the entire drive. A drive moved from one system to another may well not have the correct settings.
3. Dealt with above
4. Sounds like things are broken now, I guess you'll need to do what ever works. For the stuff that is currently in the library first copy the current iTunes folder from C: to X:\iTunes. Now click the icon to start iTunes and immediately press and continue to hold down the shift key. Choose the library on the external drive. Check the media folder has been reset to X:\iTunes\iTunes Media, edit if necessary. At this stage I recommend you have the Edit > Preferences > Advanced options Keep iTunes Media folder organized turned on and Copy iTunes Media folder when adding to the library turned off. After fixing any potential issues with file permissions use iTunes Folder Watch to add in new files from your media folders and remove those that iTunes has lost track of. You can then either consolidate the content (creating duplicate copies of anything that is located outside of the iTunes Media folder which you will then need to tidy up) or use my script ConsolidateByMoving which does pretty much just what it says.
5. If you really can't gain access to the backup media that is supposed to be on the external drive then see this post from forum regular Zevoneer for options on moving your iPod data back to your computer.

How do you make Sun Glassfish 2.1 use ocijdbc11.dll?

Hello all,
This is my first post here! I just have a question with regards to how to make glassfish 2.1 use ocijdbc.dll. I recently downloaded a reporting application called JasperServer (community edition) which I configured for use with Oracle 11g and glassfish. I have deployed the war file into glassfish after doing all the necessary steps (copying ojdbc14.jar and ocijdbc11.dll into the gf lib folder, creating an Oracle datasource using the "thick" driver, etc.) However, when I try to ping my database from gf. I get a no ocijdbc10 in java.library path error. I assumed gf 2.1 defaults the oci driver to 10 so I copied the files over from my 10gr2 database. Unfortunately, if I use this oci version against an 11g database, I get a java.sql.SQLException: ORA-01024: invalid datatype in OCI call. I assume 11g expects the dll version that came with it. What settings in glassfish should I change to make it use ocijdbc11.dll?
Thanks in advance!

How to access the data stored in Java tables in E-Commerce 7.0

For the CRM E-Commerce 7.0 Web shop all the data related order templates, Shop Id and catalog variants are not getting stored in CRM tables. Can anyone please let us know where all the details are getting stored.
By searching here, in SDN Forum we found that these details are getting stored in some java tables. If this is true kindly let us know the following points.
1). How can we access these tables.
2).Where these java tables are stored .
3).Do we have authorizations to check and modify these tables.
4).If we donu2019t have authorizations to check and modify these tables, how can we get the access to them.
4).How can we write Database Queries to retrieve the data from these tables.

I am afraid, all these three entities are in CRM tables.
Web Shops - Function module CRM_ISA_SHOP_GETLIST, Table crmm_isa_shop_h
Catalog Variants - Function module - COM_PRDCAT_GET_VARIANTS (they are also stored in CRM tables) for a given catalog.
Now for the Order Templates - They are technically order objects with system status set to "Order Template" I1034. You should be able to see them in CRM tables alongwith other orders... crmd_orderadm_h and etc...

}...but how do I access the javascript variable 'username' from the Java code?
Thanks,

The only way to pass values between JavaScript and JSP is through cookies. It sucks, I know, but right now that is the only option.
You already are creating a cookie in JavaScript. So go ahead and read it in Java:
Cookie[] cookies = request.getCookies();
for(int i = 0; i < cookies.length; i++) {
    Cookie c = cookies;
if (c.getName().equals("un")) {
// Do what you need here.

How to call a php function from java...

helllo fellow java developers!
Im trying to figure out how I can call a php function from my java code.
I know it sounds a bit unintiutive, seeing how java is a rich programming language, BUT java simply cannot do the task that the php script can do. It simply acts differently.
So I am trying to call a php function, that returns a string object, and capture that string object....
is this possible?
something like....
String strMyString = phpFunction( strVariable )
???????/ any ideaS?

idea #1 - come up with a better plan that doesn't involve invoking php from java.
Give one example of something php can do that java can't.
idea #2 - forget java, and just write it in php.
Involving multiple frameworks/languages/runtime environments is a recipe for an overcomplicated solution that will be impossible to maintain.
I'd say keep it simple and stupid, and stick with one language.
If you're still hooked on the idea, maybe try [this link|http://www.infoq.com/news/2007/10/php-java-stack]

How-to access username and password protected Java EE Web services from ADF

The title of this post is exactly the same as this article by Frank Nimphius:
http://www.oracle.com/technology/products/jdev/howtos/1013/protectedws/access_protected_web_services_from_adf.htm
The article addresses the problem of securing web services using usernames and passwords, when those web services are accessed through a proxy or a data control. In the examples, the user names and passwords are specified, whether in the code or the definition of data controls. (SKING/SKING).
In a very common scenario, users login to reach a page, for example, A.jspx, which contains a button that calls a web service, for example displayDate. Suppose that user has logged in by username/pass of (AHUNOLD/AHUNOLD) and AHUNOLD has access to the service and the page. Is there any way to pass the logged in user name and password to the webservice ? Of course we can hard-code the username in the data control definition or proxy code, but this is just one of the thousands of users who have access to the service and the authentication is not dynamic this way.
Hope my question is clear. Wishing you all a great Christmas.
Farbod

Hi Frank, and happy new year.
Are you implying that it couldn't be done declaratively? What is your suggestion for this problem? You know the problem... As I described:
- I need to secure my web services, so when exposed, no one from inside network or the internet, can access the web service without proper permission
- The web services are shown as web controls on jspx pages. The user has logged in before reaching the page. It is irrelevant to ask him to enter user name and password again.
- I have user names, passwords and roles in Oracle Internet Directory (Identity Management). It provides some APIs and I can retrieve the usernames and attempt logging in programmically. But how can I get username and password from the session in ADF application?
I guess using SAML or certificate could be the solution, but I have a problem with SAML, described here:
Re: Webservices Security, SAML, and Identity Management (OID)
