Generate Java file based on a C++ header file

Hi,
I want to know if it is possible to generate a java file and JNI-based C++ file based on the header file of C++ code which I want to call.

go to www.swig.org... swig is an exe that generates wrapper code & java JNI code. You'll need to compile & link to an so / dll yourself, but it should work

Create header file based on data in Data file

Hi,
For Data File: created an interface to extract data from table to data file.
1) Now i want to create a header file which contains info like :
Created On: #Rows Fetched:
2) I also want to create a footer, which contains info like:
SUM(AMOUNT) (amount is one of the columns of data file)
How do i implement this using an interface?
Thanks.

Step 1. Create a Variable Header - Call the count using some thing like this SELECT COUNT(*)||CHR(10) FROM TABLE
Step 2. Call it in OdiOutFile
Step 3 . Call the Interface to load from table to File using [ IKM SQL to File Append with create Header option - no ]
Step 4. Create another Variable Footer - Call the sum in the Refreshing Tab
Step 5. Call it in OdiOutfile with Append option Checked
Note - Make sure you use the same File Name for all the three places.
There are other ways too but this is simple way. Hope this helps.

Pickup the file based on the date in file name

Dear all,
I have requirement like this.
EX:
I have file name called ABC_20110721.txt , i have to pickup that file today and should not delete it and should not mark as 'Read only'. We have to keep that file as is in FTP.
I will have another file tomorrow like ABC_20110722.txt , i have to pickup this file alone.
So that means date in the file name is dynamic based on the system date( current date interface runs on )
Please let me know how can we do this?
Regards

Hi ,
    You have not specified your operating system on which PI is running. You need scripts to achieve this for you. In case you are using UNIX/Solaris/Linux server the following script "filename.sh" should run fine
lines=`expr 0 + 0`
maxlines=`expr 0 + 100`
while [ 1 -le 5 ] ; do
     d=`date +%G%m%d`
     count=`ls -1 | grep $d |wc -l`
     c=`expr $count + 0`
     while [ $c -gt 0 ]; do
          file=`ls -1 | grep $d |tail -$c |head -1`
          searchFile=`grep $file temp | head -1 | wc -l`
          searchFile=`expr $searchFile + 0`
          if [ $searchFile -eq 0 ]; then
               cp $file /home/anghosh0/sdn/f
               echo $file >>temp
               lines=`expr $lines + 1`
          fi
          c=`expr $c - 1`
     done
     if [ $lines -gt $maxlines ]; then
            k=`date +%G%m`
          grep $k temp > t
          mv -f t temp
          lines=`expr 0 + 0`
     fi
done
Say you are poutting the source files say ABC_20110721.txt,ABC_20110722.txt,ABC_20110725.txt in a directory. Say the name of the directory is    "/usr/home/dx7" . You have to put this scipt "filename.sh" in "usr/home/dx7". Set the permission bits of this script to "777" or you can use command "chmod 777 filename.sh". This script will choose only the files for todays date as per server time. This script is running in an infinite loop. Thus whenever there is a new file in the directory it checks the file name, and if the name contains todays date, it puts the file in "home/anghosh0/sdn/f" directory from where PI server picks it up for reading. Please change the folder name according to your convinience. Now in the folder "/usr/home/dx7" you need to keep a file called "temp" this file will conatin only one word or any symbol say "hi". The use of temp is to collect all file names that the script has already transferred to PI folder. Thus if script has transferred file say "ABC_20110725.txt " and "DEF_20110725.txt ", then "temp" will have contents
hi
ABC_20110725.txt
DEF_20110725.txt
This prevents same file being put to PI source directory twice. Once temp reaches a maximum of 100 lines, this script clears the contents of temp automatically, except for the lines which belong to current year and current month. You can alter this value by altering the line "maxlines=`expr 0 + 100`" in the script shown above.
This is because the file grows in length over time.Please take help of you BASIS team to put this file in correct folder and run it. It is working fine in our Linux server. Please run this as a background process with this command "filename.sh &".
I think this will solve your problem. In case your operating system is windows then Please let me know I need to write batch file for the same.
regards

Using AppleScript to create a text file, based on an OCR'd file's content

Hey guys, I've got an interesting situation.
I was wondering if there would be anyway to use something like AppleScript (or the like) to create a text document and fill it with information based on what is found in an already OCR'd file?
For example: I have a paycheck stub. The stub contains the words "Gross Pay" and the value "$xxxx.xx" on one line. Using Hazel to identify paychecks (based upon filenames), could I then use something like AppleScript, to create a new text file, and then pull the text from the line that contains the word's "Gross Pay" and insert it into the text file's next line?
Ex:
March 26,2012
Gross Pay                   $xxxx.xx
April 6,2012
Gross Pay                   $xxxx.xx
Kind of how TurboTax's iPhone app pulls text from an image, then uses the values to insert it into the app's appropriate fields?
I know this may be a lot to ask, but any help is appreciated. Thanks!

Is it a statemachine or just a bunch of crisscrossed wires?
Where do you want to add the file read?
How should the file be read (after pressing a read button, at the start of the program ,etc.)

Ther are PARAMETER LIST DISCREPANCIES in the help file vs the NIDAQ.H header file for GPCTR_Read_Buffer...

PROBLEM: The function help file contains documentation for using GPCTR_Read_Buffer with 7 parmeters in the parameter list. The NADAQ.H Header file contains 8 parameters in the function declaration. Which is right? What is the correct parameter list and can an example be provided that shows how to use the function correctly? I am currently using DAQ ver 6.92 and a 6602 Counter Timer board in a buffered start/stop or ND_BUFFERED_TWO_SIGNAL_EDGE_SEPARATION_MSR application.

Thanks for the response Filipe, I'll let you know how it goes. I only went into the header file because example code provided by NI ... paste ...
iStatus = GPCTR_Read_Buffer(iDevice, ulGpctrNum, ND_READ_MARK, ulReadOffset, ulNumPtsToRead, ulTimeOut, &ulNumPtsRead, pulReadBuf);
showed use of 8 parameters - in agreement with the header file and in disagreement with the on-line help file function documentation.

Copying file based on initial part of file's name and creation date

We have a client who dumps data in one of our 2003 SP2 server. We need a script to copy a single file from this location to
one of our 2008 R2 server.Like in the source server we have
abc_Today'sDate_hexadecimal.csv (File Name)
Today
(Date Modified)
abc_YesterDay'sdate_hexadecimal.csv (File Name)
Tomorrow (Date Modified)
'abc' is constant in the file name where rest changes. We want this file, whose name is starting with 'abc' and created today to be copied to destination, preferably replacing the file which was copied yesterday.
I know nothing about scripting so any help would be appreciated
Thanks

If you are hoping to get a complete solution, you won't as that is not the purpose of this forum.
If you are hoping to learn how to accomplish this task yourself with a little help, then this is the place for you, but...
you will be better off to start learning powershell, perhaps using this exercise as a practical example. So to start, you should type these commands in the powershell console:
help get-childitem
help copy-item
if the documentation that this presents makes no sense to you, you will have to get past the "knowning nothing about scripting" condition first. If so, someone here will no doubt provide some usefu references...

Is it possible to create a cisco config file based on a polycom config file?

Hello,
We have 12 spa509g phones that are barely working with our provider (voxox).
My provider gave me the config files that are used to set up polycom phones as those are the only phones they support.
Features that currently work: incoming calls, outgoing calls, blind transfer, voicemail, call hold
Features that do not work: call presence - solid orange lights, attended transfer, paging
I've upgraded the firmware to 7.5.6 and configured the phone through the GUI as much as i can but I can't seem to enable the above features.
Any help would be highly appreciated as I'm about to buy polycom phones if we can't figure the configuration out.
Attached are the configuration files from voxox concerning polycom phones. confidential data says "removed"
If anyone thinks that this is possible, I can send a copy of my current cisco configuration file.
Thanks,
Philip

Well, I have no polycom phone, not I have personal experience with voxox. I wish the following document may help a lot - it describe Polycom configuration somewhat. As you have no Polycom, you have no current <mac>-directory.xml. So you don't know the device name you should subscribe to. But it seems to be a DID-number.
Just try it.
On the other side, ask Voxox for help. Don't ask for configuration files, ask for configuration instructions expressed in terms of the SIP protocols. Consider switch to more friendly and technically skilled VoIP operator if they will not understand what the SIP stand for ...
By the way, wrong forum. Your issue has nothing to do with XML Phone Application interface. I'm not sure someone will respond you here.

Automatically open file based on MIME type and file extension

We have an app that is registered to handle custom MIME type and file extension. This works perfectly on IE and FireFox causing them to download the file to a temp folder and then launch our app associated with MIME type and file extension with command line to the downloaded file. On Safari however this does not work. It opens up a download window and shows that it has downloaded the file with no option to open it.

Producing header files with javah--where is everything?

Hi everyone,
I need to make my Java program work with some C++ code. I am trying to compile the classes to header files. This is the header file I get after javah-ing the class where I have the native methods I need to get from the C++:
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class client_TOMSClient */
#ifndef Includedclient_TOMSClient
#define Includedclient_TOMSClient
#ifdef __cplusplus
extern "C" {
#endif
#undef client_TOMSClient_REQUEST_TYPE_INCIDENTS
#define client_TOMSClient_REQUEST_TYPE_INCIDENTS 3L
#undef client_TOMSClient_REQUEST_TYPE_EVENTS
#define client_TOMSClient_REQUEST_TYPE_EVENTS 4L
#undef client_TOMSClient_REQUEST_TYPE_ROADS
#define client_TOMSClient_REQUEST_TYPE_ROADS 5L
#undef client_TOMSClient_TRAVELER_INFO_RESPONSE_TYPE_UNDEFINED
#define client_TOMSClient_TRAVELER_INFO_RESPONSE_TYPE_UNDEFINED 0L
#undef client_TOMSClient_TRAVELER_INFO_RESPONSE_TYPE_LINK_STATUS
#define client_TOMSClient_TRAVELER_INFO_RESPONSE_TYPE_LINK_STATUS 1L
#undef client_TOMSClient_TRAVELER_INFO_RESPONSE_TYPE_SCHEDULED_EVENT
#define client_TOMSClient_TRAVELER_INFO_RESPONSE_TYPE_SCHEDULED_EVENT 2L
/* Inaccessible static: m_tomsClient */
#ifdef __cplusplus
#endif
#endif
It's mainly the /* Inaccessible static: m_tomsClient */ that's bothering me. I have a hunch that my native methods aren't coming up in the .h file since they are described in the class TOMSClient of which m_tomsClient is the first (and only) instance.
So what am I doing wrong? Is there any way to get javah to also "look" at the static members? Or is this doomed from the start, so to speak?

Addendum:
In fact, now that I really look at it, for some reason none of my members, static or otherwise, seem to be mentioned in the .h file. I even did a test run like this:
public class Demonstration
public String publicName;
private String privateName;
public static String publicStaticName;
private static String privateStatucName;
public native void method1();
public native int method2(boolean b, byte by, char c, short s);
public native byte[] method3(byte data[], boolean b[]);
public native String[] method4(int num, long l, float f, double d);
static
System.loadLibrary("Demonstration");
And what I got was this:
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class Demonstration */
#ifndef IncludedDemonstration
#define IncludedDemonstration
#ifdef __cplusplus
extern "C" {
#endif
/* Inaccessible static: publicStaticName */
/* Inaccessible static: privateStatucName */
* Class: Demonstration
* Method: method1
* Signature: ()V
JNIEXPORT void JNICALL Java_Demonstration_method1
(JNIEnv *, jobject);
* Class: Demonstration
* Method: method2
* Signature: (ZBCS)I
JNIEXPORT jint JNICALL Java_Demonstration_method2
(JNIEnv *, jobject, jboolean, jbyte, jchar, jshort);
* Class: Demonstration
* Method: method3
* Signature: ([B[Z)[B
JNIEXPORT jbyteArray JNICALL Java_Demonstration_method3
(JNIEnv *, jobject, jbyteArray, jbooleanArray);
* Class: Demonstration
* Method: method4
* Signature: (IJFD)[Ljava/lang/String;
JNIEXPORT jobjectArray JNICALL Java_Demonstration_method4
(JNIEnv *, jobject, jint, jlong, jfloat, jdouble);
#ifdef __cplusplus
#endif
#endif
Now I am pretty sure that both public String publicName and private String privateName should have shown up in the .h file. What is going on? I'm completely confused.

SAP eSourcing 5.1 - Java/SQL based data extractor starter kit for BW

Hi,
We're implementing the eSourcing 5.1 which is fully Java based. I'm not able to find the Java/SQL based extractor for it. Does anyone have any idea where we could get the Java/SQL based extractor ? If anyone has any prior experience with extracting data from eSourcing5.1 to BW, would appreciate any advise on the best way to extract data from it, whether using standard Java/SQL based extractor or via flat files or some other methods.
Thanks in advance for your help.

HI Sivaraju,
Thanks so much for the info.
For DB connect, do you know if there's any standard extractors for it ?

Problem with File Based replication in Weblogic Express 10

Hi,
          We have Web application (exploded war) file deployed on Weblogic Express 10, to a Cluster of three Managed Servers (all three on different physical machines).
          We are using File based session persistance in weblogic.xml
          We have a shared location for all the three servers where we will be sharing the Session data.
          When we start the application, its works fine and is very fast, but after sometime the application slows down.
          Troubleshooting the Issue we found that its a problem with file based replication. By using File based replication every user session is stored in form of directory inside shared directory. So after sometime thousands of directories are created inside the shared directory where the session information is stored. So when we access the application, its waiting for lot of time with Message Session Monitor .... (this is because its browsing through the shared session storage directory for lot of time for session information as it has lot of directories) and finally after a long time like 10 mins we get the Application Home Page.
          When we clean up all the saved sessions inside shared directory, the application works fine, But we will see the same sometime later may be after 3 or 4 hours when the shared session directory has lot of session information stored in it.
          Is there a way to clean up the saved session information on file system as soon as that user session is closed by using file based replication.
          We cannot used Inmemory replication as our Appl doesnt support it.
          Please advice as it is a major show stopper in our Production Mirror env.
          Weblogic Consultant

It is possible to reduce number of live session by configuring very low timeout-secs weblogic.xml. Default is 60 minutes.
          More details are here..

Split records into two files based on lookup table

Hi,
I'm new to ODI and want to know on how I could split records into two files based on a value in one of the columns in the table.
Example:
Table:
my columns are
account name country
100 USA
200 USA
300 UK
200 AUS
So from the 4 records I maintain list of countries in a lookup file and split the records into 2 different files based on values in the file...
Say I have records AUS and UK in my lookup file...
So my ODI routine should send all records with country into file1 and rest to file2.
So from above records
File1:
300 UK
200 AUS
File2:
100 USA
200 USA
Can you help me how to achieve this?
Thanks,
Sam

1. where and how do i create filter to restrict countries? In source or target? Should I include some kind of filter operator in interface.
You need to have the Filter on the Source side so that we can filter records accordingly the capture the same in the File. To have a Filter . In the source data store click and drag the column outside the data store and you will have Cone shaped icon and now you can click and type the Filter.
Please look into this link for ODI Documentation -http://www.oracle.com/technetwork/middleware/data-integrator/documentation/index.html
Also look into this Getting started guide - http://download.oracle.com/docs/cd/E15985_01/doc.10136/getstart/GSETL.pdf . You can find information as how to create Filter in this guide.
2. If I have include multipe countries like (USA,CANADA,UK) to go to one file and rest to another file; Can I use some kind of lookup file...? Instead of modifying filter inside interface...Can i Update entries in the file?
there are two ways of handling your situation.
Solution 1.
1. Create Variable Country_Variable
2. Create a Filter in the Source datastore in the First Interface ( SOURCE.COLUMN = #Country_Variable)
3. Create a new Package Country File Unload
4. Call the Variable in Country_Variable in Set Mode and provide the Country (USA )
5. Next call the First Interface
6. Next call the Second Interface where the Filter condition will be ( SOURCE.COLUMN ! = #Country_Variable )
7. Now run the package .
Solution 2.
If you need a solution to handle through Filer.
1. Use this Method (http://odiexperts.com/how-to-refresh-odi-variables-from-file-%E2%80%93-part-1-%E2%80%93-just-one-value ) to call the File where you wish to create store the country name into the variable Country_Variable
2. Pretty much the same Create a Filter in the Source datastore in the First Interface ( SOURCE.COLUMN = #Country_Variable)
3.Create a new Package Country File Unload
4.Next call the Second Interface where the Filter condition will be ( SOURCE.COLUMN ! = #Country_Variable )
5. Now run the package .
Now through this way using File you can control the File.
Please try and let us know , if you need any other help.

VS2010: Why does my C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include does not get all the needed header files?

Hello,
I have installed VS2010 Professional. I have done a full install. The I install the 2010 redistributable and 2010 SP1. So I think I have installed all the needed products. But my include files has only 3 files :(. anmintrin.h, srv.h, wmiatlprov.h. My colleagues
who have installed the same three products have some 200 header files. My guess these header files are coming from some SDK or so. I have 5.0, 6.0A, 7.0A. 7.1A, 8.0, 8.0A SDKS installed. What am I missing?
Please check this http://stackoverflow.com/questions/13656856/cant-get-visual-studio-c-include-file-excpt-h-to-get-installed and there the person tells to practically remove all and install all and another answer says just copy it. My hope is Microsoft
might have a more logical and technical answer than doing something blindly without rhyme or reason
A clear cut answer might help the community.

Including Header files

Hi
Am a mainframe guy and new to these stuffs.
Now ,I want to compile a C++ program in Sunstudio.
My question is how & where to add the header files ?
What is the extension to be used for the header files ?
Please someone help me in this regard.

[I had replied to this yesterday but it didn't appear to show up in the thread]
The header file is added to the 'Header files' in the same project For Sun Studio, I am pretty sure that the header files listed in the project
is not used by the compiler to find the header files.
That list of header files is merely a convience for the programmer
as a reference and to quickly find and open header files used in the project.
You need to tell the IDE which directories to search for header files
(that are not standard header files)
I am presuming that the header file(s) the compiler is complaining about is not a standard library header file,
but instead is a header file associated with the source code you are compiling or are associated with
a 3rd party library required by the program.
The #include semantics, as ralphw mentioned, can be a little complex.
As a quick follow up to ralphw's response
generally #includes of the form
#include "foo.h"
indicates that the header file is in the same directory as your project source files.
Normally the compiler can find this file with some simple seach heuristics so
I suspect the offending include line is of the form:
#include <foo.h>
The <> brackets indicates that the header file is in a directory to be specified
in one of the listed include directories.
Include directories may be intrinsic to the compiler implementation
such as standard libraries and/or libraries added by the compiler vendor;
or they may be header files for 3rd party libraries or your own libraries
stored in some directory other than the application program you are compiling.
For 3rd party libraries or your own libraries, provide a list of
directories to seach for included header files.
for command line mode, in almost all c/c++ compilers these directories are listed with
the -I command line argument.
In SunStudio 12, you list the include directories in
your project properties / Parse configuration / Sun C++ compiler / General / Preprocessor definitions
If you have further questions on this, it would be helpful to know
if you are attempting to compile some preexisting code
or are you creating code from scratch.
(It sounds like you are compiling preexisting code that
presumably has been compiled correctly in some other implementation
and are trying to port it to Sun Studio.
If this is the case, it sounds like you simply need to add the
path of the directory containing the offending header file to
this list of include directories.)
It would also be helpful to know the fully qualified
file name of the offending .h file,
and the form of the #include line in the file that is being compiled.
If the #include line is of the form
#include <dir/foo.h> then you need to add the
path of the 'dir' parent directory to the include directories list.

Place function in header file?

Hello, again.
Suppose I have a piece of code that I know I am going to be using very often. Obviously, the logical thing to do is place it in a function. And, suppose that I know I'm going to be calling that function often, and in a lot of different projects. How can I best make it so that I don't have to declare and define the function in every file in every project that I want to use this function in?
Would I place the function in a header file, and then use the #include preprocessor directive to include the .h file in every file I want to use the function in? If so, why couldn't I just store the function in a .c/.cpp file? What does a header file offer over a .c or .cpp file -- why use one over the other?
Also, where do I go to create the header file? If I go to File > New File and select header file, then it creates it as a file within the project that I have open at that moment, and I'm going to want to use the file in other projects. Is there somewhere I can save the header file outside of any specific project, so that I can include it in any project I want?
Thanks.

So, technically, I could define the entire function in the header file, even without declaring it as inline, and I wouldn't have to define it in a source file?
Nope. You'll get linker errors, or at least warnings, about the function being defined twice.
1.) Why define it in a source file in the first place? Why not always define it in the header file? I can imagine there's obviously a very good reason for this -- I'm just curious what it is.
Code bloat and the sheer inefficiency of having the same code duplicated everywhere.
2.) You said that if the function is defined in the header file instead of a source file then it is treated as a macro and the whole function is picked up and dropped in your code wherever it is called. This sounds like the same thing as an inline function, so if you did define the entire function in the header file, what would be the difference between defining the whole thing in the header file using the inline keyword, versus defining the whole thing in the header file without the inline keyword?
Well, it is an inline function. You must use the inline keyword.
3.) Finally, if I did decide to define the entire function in the header file and not use a source file, would I still need to write the function signature as well, or just the definition?
Just the definition.
