Problem with JCA calling to DB function from Service Bus

Hi there
I have managed to use JCA from the Service Bus on several tables, on some diferent Oracle databases and it worked OK.
Now, I try to use it with a DB function that I have defined. Calling to this function from any DB software returns good values.
But calling this function using JCA (adapter created with jDeveloper) on OSB gives me the correct answer except that instead of the data there are question marks, like +<param>???</param>+
The database encoding is ISO-8859 (by using "SELECT * FROM NLS_DATABASE_PARAMETERS") .
This encoding is the same as was on different databases that worked ok with other adapters, just not calling a DB function, but a custom SQL.
I would appreciate if anyone might know what can solve this ..
Thanks

Where are you checking the content of the XML?
It seems that platform's default encoding is not able to identify those characters and hence dispalying those as "???". Sometimes you get some invalid characters (like null), in the XML file and when platform's default encoding could not identify those characters then they get displayed like "?". Please check the content of the XML to verify it does not contain any invalid XML characters (sometims null). You may try to log the XML in database and in OSB to see it's content.

Calling a JavaScript function from an JApplet...

Can anyone help? Is it possible to call a JavaScript function from within a JApplet? If so, what is the syntax? I've seen reference to the Netscape package but I've been led to believe it doesn't always work within Internet Explorer 6 which is the target browser.
If the above is not possible can anyone tell me if and how it is possible to load images from outside the init() method of a JApplet? This would allow me to work around the problem.
Thanks in advance - Jim.

Intermittent problem with TestStand calling CVI DLL calling MSCV DLL

Sorry about cross post, but I am not sure which group is best to address
this issue.
Setup:
Windows 2000 SP1
TestStand 2.01f
CVI 6.0
MSVC++ 6.0 SP5
Problem:
I have a CVI Test Library DLL that contains test functions called by
TestStand using the C/CVI adapter. The CVI Test Library DLL in turn makes
several calls to another DLL written in MSVC++. I am experiencing an
intermittent problem with one of the MSVC functions. The problem ~appears~
to be stack related, but I am not sure. Among other things, this MSVC
function accepts a const char * argument that is a TestStand lookup string.
The function uses this string to access the TestStand API.
What happens is this: Everything works fine. I then recompile the CVI DLL
after making some mod, then run. The MSVC++ DLL asserts that the const char
* arg passed by the CVI DLL is NULL. However, this is not the case if I
single step through the CVI code. It has happened both with passing
variables as the const char * argument and as hardcoded strings literals, so
its not that I am actually passing NULL. The other argument to this
function is the TestStand sequence context dispatch pointer (LPDISPATCH
pobjSequenceContextDisp) and it always ~appears~ to be passed correctly.
The problem is frustrating and hard to debug because I can not
deterministically reproduce it. The problem ~never~ appears when I debug my
MSVC++ DLL in Visual Studio. And it only occasionally appears otherwise.
The problem, when it appears, always appears on the first run after
recompiling the CVI DLL, though the problem does not happen after ~every~
recompilation. I'd say it happens 1 in 6 times after a recompile.
Recompiling the exact same code does not always make the problem disappear.
If I change the CVI code (code that has nothing to do with the argument
itself though) and recompile the problem almost always goes away. Selecting
'Mark all for compilation' and rebuilding does not make the problem go away.
Only tweaking the CVI code and recompiling does (usually).
Whats more, the problem appears:
* With the CVI DLL built as Debug or Release mode.
* With the CVI default calling convention set to __stdcall or __cdecl.
* With the C/CVI TestStand adapter set to run in-process or external
instance of CVI.
The problem appears to be some sort of stack or argument passing problem
between CVI and MSVC, though thats just a guess based on the symptoms. I
have quadruple checked the calling conventions of all declared functions.
The CVI DLL functions all use TX_TEST (which resolves to __cdecl). The MSVC
DLL functions all explicitly use __stdcall. Is there a problem with calling
__stdcall MSVC functions from a __cdecl CVI function?
I can find no other memory leaks or indications of memory corruption
elsewhere in either the CVI or MSVC DLLs. Its only this one function that
exhibits this strange 'null const char *' problem.
Can anyone offer any ideas about what may be causing this problem? Anything
else I should check/verify?
Regards,
Joe

I was under the impression that as long as everything was explicitly and
consistently declared, you could safely mix cdecl and stdcall f
unction
calls. Is it bad to do this? Is this a known issue with the CVI compiler?
I've never seen a problem with doing this under MSVC++.
I'll try wrapping them in cdecl calls for CVI - though we have a
depressingly large number of stdcall functions in the MSVC DLL ;-). They
need to remain stdcall in the DLL because we also call them from Visual
Basic.

I verified that the MSVC DLLs were either ALL Debug or Release. I too have
seen nasty problems when MSVC Debug and Release is mixed.
One thing I had not thought of until your reply: What about mixing CVI Debug
DLLs with MSVC Release DLLs? Have you ever seen issues with doing this?
Thanks!

How can I call a plsql function from an attribute?

I have an attribute defined in an element. I want execute a PLSQL function from the attribute, and display the returne value with an HTML template.
I've defined the attribute's type like PLSQL, and I've put the called of the function in the value of the attribute, but it doesn't work. The only value I obtain is an URL (I think that is the URL of the function or someting like this).
How can I call to my function from the attribute and display the returnes value in the page?
Thanks.

Thanks, but it doesn't work. I have an attribute called ID_BOL and I want to associate a sequence to that attribute. I've created a function, with the sequence. This function return de value of the sequence. I want taht the attribute takes the value of the sequenece dinamically.
I've tried it, creating the type attribute like PLSQL, and calling the function from the attribute, but it doesn't work.
How can I return the sequence value to my attribute?
Thanks.

Help needed in calling a javascript function from a jsp

Hey guys,
I need help.
In my jsp I have a field called date. When i get date field from the database, it is a concatination of date and time field, so I wrote a small javascript function to strip just the date part from this date and time value.
The javascript function is
function formatDate(fieldName)
          var timer=fieldName;
          timer = timer.substring(5,7)+"/"+timer.substring(8,10)+"/"+timer.substring(0,4);
          return timer;
Now I want to call this javascript function from the input tag in jsp where I am displaying the value of date. Check below
This is one way I tried to do:
<input size="13" name="startDate" maxLength="255" value=<script>formatDate("<%=startDate%>")</script> onChange="checkDate(this)">
I even tried this:
<input size="13" name="startDate" maxLength="255" value="'formatDate(<%=startDate%>)'" onChange="checkDate(this)">
But it dosen't work
Please help. I am struggling on this for days.

IP - Is it possible to call exit planning function from ABAP Report..

Hi All,
Greetings.
Is it possible to call exit planning function from ABAP Report (t-code SE38) ? Or I mean is not limited only to be called from ABAP Report, perhaps from BSP / Web-Dynpro / Function Module.
If somebody here has been doing it before, I'm keen to ask to kindly share it. Particularly how to call and transfer data to that exit function.
Or if somebody has done in BPS, appreciate if it can be shared too .
Thanks a lot and have a good day,
Best regards,
Daniel N.

Hi.
You can achive this as suggested by Mattias in your previous post.
Lets say you have next data structure:
CostCenter | Amount | PercentForDistibution |
Create input ready query in this format. Restrict cost center by variable type range.
Create WAD with analysis item.
When you run web page you enter range of cost centers (lets say you will enter 101004 to 101010).
I assume you have data only for 101004 in your cube (lets say 1000).
You will see only one record in your webpage.
CostCenter | Amount | PercentForDistibution |
101004       | 1000     | NOTHING
When you create WAD in analysis item properties set "NUMBER_OF_NEW_LINES" to lets say 1 (so in WAD you will see always one blank line for entering new data).
Just add 6 new records:
CostCenter | Amount   | PercentForDistibution |
101005       | NOTHING| 10
101006       | NOTHING| 30
101007       | NOTHING| 20
101008       | NOTHING| 25
101009       | NOTHING| 5
101010       | NOTHING| 10
Then run planning FOX function like this:
FOREACH Z_COST_CENTER.
IF {Amount, Z_COST_CENTER} <> 0
Z_AMNT_TO_DISTRIBUTE = {Amount, Z_COST_CENTER}.
ENDIF.
ENDFOR.
FOREACH Z_COST_CENTER.
IF {PercentForDistibution Z_COST_CENTER} <> 0.
{Amount, Z_COST_CENTER} = Z_AMNT_TO_DISTRIBUTE * {PercentForDistibution Z_COST_CENTER}.
ENDIF.
ENDFOR.
It is not perfect FOX, but as an idead, it should work.
Regards.

Chart - problem with realize one of the function under CR XI

Post Author: mrowa
CA Forum: Charts and Graphs
Hello,
I have
problem with realize one of the function under CR XI. I would be persuade if
any of us would like to help me.
1)
1) From
database (basically from one table), I take data to make report. Each of record
have appropriate fields:
dteData
intYear
intMonth
intDate
2)
2) I
want to realized comparison data from two or more periods of time on one chart
and in one table. For easily explanation I will describe problem on two
periods.For instance, user want to display and compare
on chart date (type monthly -sum data of each month) from 2007.02 u2013 2007.05
with date from 2006.03 u2013 2006.06. So we compare month 2007.02 with 2006.03;
2007.03 with 2006.04; 2007.04 with 2006.05; 2007.05 with 2006.06
On char I would like to display bars with comparison
of months.
Problem is that I donu2019t know how to write
something similar. I can use one period without any problems, but two and mores
I canu2019t realized.
Detail description:
I passed
two parameters two report:
{?from}, {?to} u2013for first period
{?offset}, it means {?from}+{?offset},
{?to}+{?offset} - for second period
On axis Y I have Sum(intDate);On
X (year + month). But on each value x( example 20007.02) I need to have
two values (bars). Value for standard period and offset.
For example for x=2007.02, I need
two bars one equal 2007.02 and second with offset u2013 2006.03
Movement to next value (bar) is
persuade by fields {data.rok}&{data.month} first or second period. This is
combination of two elements year&month defined under Formula. Problem
persist in that both period has different year.month and here problem starts once
again. I donu2019t know how to solve it. I have found out one solution but it
limits user only for two periods (I want to compare more).
My idea for compare only two
periods:
I make one query in CR for one
period and second query for second period.
Firs query:
"SELECT
       year ,
      month
Second query
"SELECT
       year + FLOOR({month + offset} % 13),
      {month + offset} % 13
Then in CR I connect two periods and
make u201Ctableu201D (results of queries) with JOIN on fields year and month.
This solution is not functional,
because I need to make reports for days and hours as well. In this solution I
canu2019t use (%31), because not all months has 31 days.
I use CR in WEB app made in Visual
Studio 2005. Maybe from aspx we can manipulate with date to get exact solution,
and solve problem with SELECT.
Hope my description clearly
describe problem and someone will be able to help me. I would be thankful.

I have had similar problem before.
Because I had too many data, the legend would not display all the data. Also the chart would not display all the data. But I was able to find a work around.
In your case, Right click on the Legend text and click on Format Legend Entry.
Change the font of the legend to 4 (which is the minimum). This may work.
If you are also having problem with data labels, you could change the font size of the data labels.
Hope this helps.
Thank you.

Calling a java function from xquery

Hello,
I'm pretty new to ODSI and xquery, so forgive me if what I'm asking is too trivial, but I need to find a way to call a java function from inside xquery. I know xquery can do this through external functions, but can't find any example on how the query prolog declaration should be, nor how the function should look like. Could someone enlighten me?
Thanks,
Pedro Ivo

You can do this 2 ways that I know of (Mike probably has more ideas too)
1. Register an inversion function:
[How to use an inversion function|http://download.oracle.com/docs/cd/E13167_01/aldsp/docs32/dsp32wiki/Using%20Inverse%20Functions%20to%20Improve%20Query%20Performance.html]
2. Create a physical data service based on a java function. I have used this approach for both custom JDBC database operations and straight Java processing, with pretty good results.
Good luck,
Jeff

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]

Call a Java Function From Abap

Hi, I need to call a java function from ABAP, I have a WAS 640 to deploy the module.
I have found this tutorial...
[ABAP calls Java via RFC|/people/thorsten.franz3/blog/2008/11/21/abap-calls-java-via-rfc-1-introduction]
The problem is that it uses a newer version of WAS and it implements EJB 3.0 wich only works on Java 5, but my WAS has java 1.4.2.
Anyone knows how to adapt this Blog to a WAS 640 version ?
Or Perhaps there is another way of doing this, maybe publishing my function as a web service.
Regards.
Mariano.

Why don't you expose your Java functionality as a Web Service and consume it in ABAP program. That should be much easier and the web service can be used in other places as well.
Best regards,

Problem with the MVMapView.print(printMapDiv,) function.

Hello,
I have a problem with the MVMapView.print(printMapDiv,) function.
My FOIs are displayed correct on the screen but on the printed letter
the stroke(border) color and the labels of a circle are not displayed.
the fois have a custom style:
var xmlDef = '<svg width="1in" height="1in">'+
'<g class="marker" '+
'style="width:40;height:40;stroke:0xff0000;fill:0x00ff00;stroke-width:1.5">'+
'<circle r="20"/>'+
'</g>'+
'</svg>';
markerStyle = new MVXMLStyle("my_vector_icon_" + i + '_' + j, xmlDef)
and are created like this:
v_result = new MVFOI(p_geofeature.foiId, p_geofeature.foiGeomertyObject, markerStyle, null, 30, 30);
v_result.setHTMLElement('1',0,0);
Browser: I can see the map with a green circle, a red border and '1' as a label on
top of the Circle.
Printed Letter: I see the map with the green circle but no red border Color and no label.
The implmentation of the printing function uses the same techique like the "Oracle Maps Tutorial"
It is a javascript function called through a href link:
function mapPrint()
var a=document.getElementById("printmap");
global_gdi.mapviewer.mapview.print(a);
Version is Ver11_1_1_5_B110527
Does anbody know how to print the map properly including the contents of the
MVFOI class set trough setHTMLElement function?
Greetings
Andre

Thanks for your reply but it is not working and i can prove that.
I have a small example based on the mapviewer print tutorial. To run it you need a
mapviewer installation and copy the text into a html file. In the browser you can see
a green point with a red border and red label text on a map.
If you use the print button everything except the label text will be printed.
I think this is a mapviewer css-api bug.

Calling Procedure or Function from Interative Report

Hi All -
Is it possible to call a procedure/function from "Region Source" of Interact Report page.
Basically the report I want to show would be little difficult if I use SQL alone. So wanted to check is there is a way I can call a SQL procedure/function from Apex Interactive Report Page.
Please share your expertise.

Need help to call a simple function from within another function?

I created a movieclip which has a function in its one and only frame.
function testx() {
x = x+2};
This movieclip is in the main timeline (in its own layer).
In another layer on the timeline I have created a single keyframe with a button instance called myBtn
myBtn.onRelease = function() {
var x
x =2
testx(2);
trace (x);
What I want to do is call the function in the movieclip frame from the button press function. However, I can't seem to reference it properly.
Can anyone help me to basically call a simple function from within another function?

Yes am using CS4. Have saved it as CS3 now. Ok the file is somewhat complicated and what I am testing is not what I ultimately want to do but if I can pass that variable I can figure it out. In terms of describing the file I think the only parts of importance are what I put in my previous post (please let me know if there is something I should be telling you that I have missed). I am 99.9% sure that I am using the correct instance name.
Scene1 Layer3 Frame1 has the function call for the button.
myBtn.onRelease = function() {
var x
x = 2
testx(2);
trace (x);
Slideshow layer //Actions Frame1 has the function
function testx(x) {
x = x+2};
thank you so much for helping me.

[iPhone] Calling Objective-C function from a standard-C function

How can I call an Objective-C function from a standard-C function?
I can call standard-C functions from an Objective-C functions but I can't do the inverse, how can I solve the problem of the *error: 'self' undeclared* ?
Here below is the example code:
- (void)animateView: (UIImage *)image fromPosition:(CGPoint) location1 toPosition:(CGPoint) location2
- (void) touchesEnded:(NSSet*)touches withEvent:(UIEvent*)event
[self animateView:newImage fromPosition:location1 toPosition:location2];
void dessineItemesAnim(int iteme, int final)
[self animateView:newImage1 fromPosition:location1 toPosition:location2];
*error: 'self' undeclared (first use in this function)*
}

Either add another parameter that contains a reference to the instance you are trying to call (just like many of the various API functions that use a 'C' language callback offer a 'user data ' parameter that can be used for this purpose) or create a global variable reference to the instance.
Once you have the instance reference, then you can use it in the same way that you would from within an obj-c function.
Of course, all of this assumes that you are using the standard GCC compiler that is told that your source is objective-c.

Problem with shares on Windows 2003R2 server from a Windows 8.1 PC

I'm having problem with shares on Windows 2003R2 server from a Windows 8.1 PC. It times out when I try to copy a file from my PC to the server and I get an error message saying "There is a problem accessing network drive W:\. Make sure you are
connected to the network and try again."
I have no problem copying files from the server to the PC.
Any ideas?

Hi,
How about your problem now? Have you test other machine also installed Windows 8.1? Did they have this problem?
To diagnose this problem, firstly, please check Windows 2003R2 firewall settings, also can disable firewall temporarilly for test.
Secondly, try to use Network Monitor to capture network communication package for test.
