Need to return String from C Program to Java

I need to execute a C Program, which returns a string, from my java application. I was thinking of using RMI to execute this C program. Any idea ?

There are lots of ways to do this. The simplist is probably for the C program to write it's output to a temporary file, and then have the java program read that file. Or, you could open a socket and pass the string that way (say, have your java program listen on a port and have the C program open a connection to the java program and write it's string).
Hope that gives you a starter

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).

Returning strings from OLE2 Word object (Forms 4.5)

Below is an example of how to return string and numeric values from OLE2 objects. In this example the OLE2 object is a MS Word document, and I want to fetch all the bookmarks in the Document into a Forms 4.5 Varchar2. To do this I first need to get the count of bookmarks.
Getting a string property from an OLE2 object is a common OLE2 requirement but is poorly documented. This is the ONLY way it can be done, as OLE2.INVOKE_CHAR returns a single character not a string. Use OLE2.INVOKE_OBJ, then OLE2.GET_CHAR_PROPERTY which does return a string, as shown below, to return a string from an OLE object (or OLE property).
Also note how you can only get the child object from its parent, not the grandchild (etc) object, so multiple (cascading) GET_OBJ_PROPERTY calls are required.
/* by: Marcus Anderson (Anderson Digital) (MarcusAnderson.info) */
/* name: Get_Bookmarks */
/* desc: Returns a double quoted CSV string containing the document*/
/* bookmarks. CSV string will always contain a trailing comma*/
/* EG: "Bookmark1","Bookmark2",Bookmark3",Bookmark4", */
/*               NB: This requires that Bookmarks cannot contain " chr */
PROCEDURE Get_Bookmarks (pout_text OUT VARCHAR2)
IS
v_text           VARCHAR2(80);
v_num                         NUMBER(3);
     v_arglist OLE2.LIST_TYPE;
     v_Application     OLE2.OBJ_TYPE;

               /* Set v_num = ActiveDocument.Bookmarks.Count */
v_ActiveDoc := OLE2.GET_OBJ_PROPERTY (v_Application, 'ActiveDocument');
v_Bookmarks := OLE2.GET_OBJ_PROPERTY (v_ActiveDoc , 'Bookmarks');
v_num := OLE2.GET_NUM_PROPERTY (v_Bookmarks, 'Count'); -- NB: Returns numeric property

FOR v_i in 1..v_num LOOP
                    /* Set v_item = ActiveDocument.Bookmarks.Item(v_i) */

Need to return data from a query in different ways - Please help

We are using 10g R2
I have a proc as follows that has a query with over 100 values in the select clause:
proc one( input param1, input_param2,.... output_cursor )
as
begin
open cursor for
select ...about 100 values with most of them being calculated
from table1, view 1, table2, table 3, view 2 ...
where ....
and table1.col1 = input param1
and table1.col2 = input param 2
and view1.col5 = input param5...
end;
I need to return the data that comes from the above query in different formats, columns for a report would be different from columns for screen A and different for screen B. I need only certain columns for a report and different set of columns for another screen. I have wrapper procs that get different input params. From the wrapper procs I intend to call the above proc but would like only selected values.
How can I accomplish this? Since my main goal is to select different columns for each wrapper I was thinking of insert the data from the above proc into global temp table and selecting whatever columns and order I want from the wrappers.
What do you think? Any other solutions?
Thanks
Edited by: user565033 on Jan 21, 2013 7:50 PM

You need to clearly separate roles and responsibilities. The PL/SQL code that creates and supplies a cursor handle is server code tasked to supply data. The code that makes the call for server data, is responsible for formatting and rendering that data.
Thus moving data formatting into the server code needs to be question. Simple example. Cursor does not return invoice date as a date - but formats it into a string using TO_CHAR().
This works for client1 - as that is the date format expected. However, client2 has different International settings and specifies a different date format. Invoice date, formatted into a string by the server, now renders in the wrong format on client2.
Server code should not be concerned with rendering and formatting of data send to a client.
As for the idea to use a global temp table is ..., well to put it nicely, it smells. Badly.
The single most expensive operation on a database platform is I/O. And now you want to read server data and write it to temporary storage, and the read data from temporary storage to return to the client? What on earth for!? Why purposefully increase the size of the I/O workload? Why decrease performance and undermine scalability?
Provide a proper abstraction interface to the client. Enable it to specify (as simplistically as possible) what it wants ito data. There are a number of ways to design and implement this in PL/SQL. Simplistic example:

Returning strings from Java- C JNI calls

<newbie to JNI>
I have an application written in Java that accesses a .DLL written in C. The .DLL does low-level communication to a hardware device. I've got it all working except for one little problem:
For all of the functions I need to return an integer return code and for some of them I also need to return a string, such as a serial number, version string, or whatever.
Try as I might, I can't find any information on how to return two values from a function call (pretty sure I can't in Java).
SO, I tried to find out how to stuff the version string into a string object variable in the class object the DLL API is defined in. I can't figure out how to do that either...
e.g. the following Java code:
class LLDev {
/* --- Load the .DLL -------------------- */
static { System.loadLibrary("LLDev"); }
/* --- Error Codes ---------------------- */
public static final int LLDOk = 0;
public static final int LLDInitErr = -1;
/* --- Public Variables ----------------- */
public static String DLLVersion;
/* --- Public Methods ------------------- */
public native int InitLLDev();
When I invoke LLDev.InitLLDev() from Java I want the C .DLL function Java_LLDev_InitLLDev to put the DLL Version string in the LLDev object's DLLVersion field and return an error code as the function result.
Is this possible???? Is this the right way to do this?? I tried to define the API with methods that return strings instead of integer return codes but the customer using the class wants all of the methods to return a return code in case of some error (e.g. reading the serial number from the device could fail...)

1. In general, the java way to deal with errors is by throwing exceptions, not using return codes. But OK, you are stuck with the user requirement.
2. I suggest you have the native method take as an argument a java object which will accept a string as input. In other words, it has a string "setter".
3. So in your native method, if the function succeeds, it writes your string result to that object, and you can futrther process it when the native method returns a "success" code.
4. There are JNI methods for
o looking up the class of a java object.
o looking up the method of a java class.
o invoking the method.

Why returning string from java stored function failed ? HELP ME, PLEASE

This comes up periodically. It just isn't possible using that type of approach. Probably the best you could do is the create an ADT (containing collections) and use that to pass a 'batch' of information.
Hopefully this will get addressed in the next release of the database.

Returning values from JNI functions to Java

I have a JNI function which returns a "jstring" to the calling Java function.

Trouble returning String from JNI method

I'm a JNI newbie who is going through the SUN online book on JNI and have put together the 2nd program example (right after "helloworld"), but it is not working right. It is supposed to prompt you for a string, then returns the string that you type in. Right now it compiles without error, but it returns only the first word that I type, not the whole sentence. What am I doing wrong?
Here's the code:
Prompt.java
package petes.JNI;
public class Prompt
    private native String getLine(String prompt);
    static
        System.loadLibrary("petes_JNI_Prompt");
    public static void main(String[] args)
        Prompt p = new Prompt();
        String input = p.getLine("Type a line: ");
        System.out.println("User typed: " + input);

}Thanks in advance!
/Pete

OK, I have something that works now by substituting fgets for scanf. I have two other questions:
1) Do I need to free the memory created in buf? Will it allocate memory every time the method is run? Or will it allocate only once on creation, and so is no big deal?
2) A minor question: When I run this program in eclipse, the prompt string is displayed in the console only after the input string is entered and displayed. It works fine when I run it from the command line however. I have a feeling that this is a problem with how Eclipse deals with native methods and perhaps nothing I can fix. Any thoughts?
Thanks

Return String from Oracle stored proc using Excel 2003 VBA

OS: Win XP SP3

Ora Client: 11g
By trying different things I have noticed, that I could have troubles with the ODBC-connection. Maybe I am not using the right one. To store data returned from select statements I have an ODBC-Connection (Driver: Oracle in XE), which works perfectly, e.g.:
Sub Extract_Data()
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim db_name, UserName, Password As String
cn.Open db_name, USerName, Password
sql_statement = "SELECT some_text FROM some_table"
Set rs = cn.Execute(sql_statement)
rs.MoveFirst 'jump to the first entry in the data list
Row = 2
While Not rs.EOF
'save the data to a worksheet
ip.Cells(Row, 2) = rs(0).Value
Row = Row + 1
rs.MoveNext
Wend
End Sub
Now I need to execute a stored procedure to return a semi-colon delimited string.
I have tried the following:
Public Sub obj_class()
Dim cn As New ADODB.Connection
Dim strSQL, cn As String
Dim adoCMD As ADODB.Command
Dim adoRS As ADODB.Recordset
Set wb = Excel.ActiveWorkbook
Set ih = wb.Sheets("InfoSheet")
cn.Open db_name, UserName, Password
Set adoCMD = New ADODB.Command
With adoCMD
.ActiveConnection = cn
.CommandText = "S#mdb$stg_da_extr_util.get_all_classes_of_classif"
.CommandType = adCmdStoredProc
.Parameters.Refresh
'------ and here comes the error saying:
'------ could not find the object in the collection corresponding to the name or ordinal reference requested by the application
.Parameters("i_caller").Value = "'STG_DATA_REQUEST'"
.Parameters("i_obj_classif_id").Value = 120
Set adoRS = .Execute()
End With
End Sub
I did asked on the forum:

but unfortunately without success.
Could it be, that my ODBC-connection is wrong? When debugging the connection string, I find the Provider=MSDASQL5.1.
I have moderate knowledge in VBA, but absolutely a newbie with Oracle DB. Is there any source of information that can help solving this issue? Looking forward to hearing from you, as I am almost giving up... ;(

My VBA is super rusty. Does that error come after Parameters.Refresh, or after .Parameters("i_caller").Value = "'STG_DATA_REQUEST'"?
If it's the second one, you'll need the definition of the stored procedure so you can see what parameters it's expecting. That'd mean you're getting something wrong with the names.

Return code from ABAP program in process chain?

Hi,
I have situation where I want to run some little part of my process chain only on mondays. So I am thinking of writing a little bit of ABAP that checks if is monday today. If it is, then return true, and if not return false. Then I want to branch on the outcome of my ABAP process...
...but how do I return that value?
...and what about the overall status if I use this trick to branch off?
I have looked at:
How to Integrate an ABAP program in a process chain.pdf
How to Implement custom-defined process type.pdf,
but those documents have not lead me to a solution yet...
Best regards,
Christian Frier

Sorry I missed the code:
