Memory Allocation problem when using JNI

For a Project we need to interface Labwindows-CVI/ Teststand with an application written in Java. we are using JNI. The code uses JNI_CreateJavaVM to start a JVM to run the Java interface code. The code did run for some time , but now ( without any obvious change nor on the CVI side neither on the Java side) JNI_CreateJavaVM fails with -4 error code, that means that the start of the JVM failed due to memory allocation failure. First investigation showed, that even if Windows Task Manager shows about 600M free physical memory, you can allocate in CVI only about 250M as a single block at the time we are calling JNI_CreateJavaVM. That might be a little bit to less as we need to pass -Xmx192m to the JVM to run our code. Unfortunately just increasing the physical memory of that machine from 1.5G to 2G doesn't change anything. The free memory showed by Task Manager increases, but the allocatable memory block size does not. Are the any trick to optimize CVI/Teststand for that use case ? Or maybe known problems with JNI ?
Solved!

hi,
have you tried other functions to allocate memory?
the -Xmx command only sets the maximum heap size. You can try to use -Xms. This command sets the initial Java heap size.

I have problem when use 'JNI'

Hello every body,
I have an application language "C", which, I must make a wrapper java.
To do this using "JNI".
First I try to understand the functioning of JNI, I try it for the first example helloWorld.
all steps works well, and dynamic library was well create: libHelloWorld.so
The execution, it does'nt work
When I try to java Helloworld, here's what I see:

at java.lang.Runtime.loadLibrary0(Runtime.java:822)
at java.lang.System.loadLibrary(System.java:993)
at HelloWorld.<clinit>(HelloWorld.java:7)
Although I added the link to my library like this:
export LD_LIBRARY_PATH = $ LD_LIBRARY_PATH: / home / Install / java / jniexamples / HelloWorld
I dont understand where is the problem may be in the version I use of java, I use jdk-1.5.0-13?
Thank you in advance for your help

Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/java/jniexamples/HelloWorld/libHelloWorld.so: Can't load IA 32-bit .so As a guess that would suggest that it found a file (thus the name is correct) but that the contents do not represent a shared library that the VM will load.
That is usually because the compile/link options are wrong for the target VM.

IOS app crashes on return from cameraUI - a memory allocation problem?

hey all
trying to finish my first app
when running on iOS, the app SOMETIMES crashes after returning from cameraUI (either "use"/MediaEvent.COMPLETE or "cancel"/Event.CANCEL).
when i exit some other running apps on my iPhone 3Gs (and not that many are open), the problem goes away, which makes me think this is some memory allocation problem
in that aspect, can i trust the iOS to exit inactive applications to allocate more memory for my, currently active, AIR app?
(there is no memory leak)
this is an iPhone 3Gs running os version 4.3.5
the app was made with Flash Pro 5.5 overlayed with the AIR 3.1 sdk, and deployed using the "deploy for app store" type (which should be the most bug-free)
(no crashes on Android or desktop versions)
anyone had this cameraUI problem or a similar one where an app crashes if more then some numbers of apps are open?
thanx
Saar

I don't get this. Its beyond frustrating:
we are not talking about using an uncommon phone capability, access to a phones camera is about the most basic native level of access you would be looking for in a mobile framework
we are not talking about an edge case in usage, just trying to take a simple picture consistently
we are not talking about a feature issue where it doesn't quite work the way you want, it crashes the whole app hard!
we are not talking about a hard to recreate, only happening to a few people case - it seems from what I have read the Camera integration is fundamentally broken and I have spent days researching this and only found frustration from people out there
we are not talking about an issue that does not have consequences - in several places on this forum and others people have emphasized how it is affecting their platform decisions, ability to submit apps. You even have people on this board recommending that not to use Flex Mobile and move to other platforms. Not what you want to be happening to when you are at the adoption phase of a new product.
And that is the response - on this thread and here http://forums.adobe.com/message/4125590#4125590 - we know its an issue but we don't know when it will be fixed and no proactive communication on status - only a growing body of people like me getting increasingly frustrated. What does it take for an issue to be a show stopper? priority 1? affecting customer decisions priority?
In my case I am in place where I am trying to make a platform decision and since this experience has happened I have subscribed to the live feed for this forum and as many relevant Adoble blogs, news feed etc. as I could find. I did this to get a feel for how well Adobe is supporting the mobile development on the AIR platform. Something increasingly important given recent decisions.
My perception so far is quite poor especially for a recently released product, i.e. 4.6 release. In fact the release that finally addresses performance enough to make AIR mobile development a risk free decision. You would expect Adobe to be all over the boards like this - with core developers, platform experts contributing actively. My perception, rightly or wrongly, is of a community trying to support itself without much help, or clear communication from Adobe. In fact if you look at the the articles coming out of Adobe recently its all phonegap, html5 etc. It does not fill you with confidence for the future.
To be clear - I have had a great experience with actionscript, flex etc and as a company we have developed the backend portion of our platform solely on Flex. I don't believe that we could have done it any other way and even now when I look at the alternatives for web development I feel vindicated in our decision.
However, this rant is caused by a genuine frustration and fear. I don't expect this to get a meaningful response but maybe if there are enough voices it will create an overall improvement.

AV when using JNI

Hi,
We have faced a problem that is very similar to the one reported in this thread:
http://forums.bea.com/bea/message.jspa?messageID=200010160&tstart=0
Has the problem been fixed in a later release?
We are using BEA JRockit 5.0 R26.4.0-63 under Windows XP Professional 32-bit SP2 and still get Access Violations when using java.lang.Class.getDeclaredMethods() or java.lang.Class.getDeclaredFields(). The exception does not occur when we use the same module with Sun JVM and MS JVM.
If the problem is supposed to be fixed, I can provide more details.
Best regards,
Alex

Hello Staffan,
Thanks for your reply. Here is a description of the first problem we have faced:
When using JNI to call the java.lang.Class.getDeclaredMethods() or java.lang.Class.getDeclaredFields() method, we get the java.lang.NullPointerException exception in some cases. If we debug the java.exe process in Visual Studio 2005, we can see that the following exception occurs:
First-chance exception at 0x7d612b73 in java.exe: 0xC0000005: Access violation reading location 0x00000010.
Here is a part of the exception call stack:
7d612b73()

We have done some investigations and found out that the problem occurs for the following classes:
java.lang.Class, javax.swing.JPanel, javax.swing.JLayeredPane, javax.swing.JToolBar, javax.swing.AbstractButton, javax.swing.JLabel,
javax.swing.JScrollPane, javax.swing.JViewport, javax.swing.JTable, javax.swing.CellRendererPane, javax.swing.JScrollBar, javax.swing.table.JTableHeader, javax.swing.JMenuBar, javax.swing.JComboBox, javax.swing.JSpinner, javax.swing.text.JTextComponent
While the exception does not occur when calling methods of the following classes:
javax.swing.JFrame, java.awt.Frame, javax.swing.JComponent, javax.swing.JRootPane, java.lang.Object, java.awt.Component, java.awt.Container, java.awt.Window, java.awt.Dialog, javax.swing.JDialog
We were able to reproduce the problem with Eclipse 3.1.2 launched in the following way:
I:\Java\jrockit-R26.4.0-jdk1.5.0_06\jre\bin\java.exe -Xms40m -Xmx256m -jar D:\Eclipse\startup.jar -os win32 -ws win32 -arch x86 -launcher D:\Eclipse\eclipse.exe -name Eclipse -showsplash 600 -exitdata 14a8_60 -vm I:\Java\jrockit-R26.4.0-jdk1.5.0_06\jre\bin\java.exe -vmargs -Xms40m -Xmx256m -jar D:\Eclipse\startup.jar
I:\Java\jrockit-R26.4.0-jdk1.5.0_06\ - the installation folder of JRockit JDK
D:\Eclipse\ - the root folder of Eclipse
In this case, even trying to get information about the java.lang.Object class fields and methods causes the problem.
Can you say anything based on the above call stack?
Please let me know if you need any details about the problem.
Best regards,
Alex

ORA-01403: no data found Problem when using AUTOMATIC ROW FETCH to populate

ORA-01403: no data found Problem when using AUTOMATIC ROW FETCH to populate a form.
1) Created a FORM on EMP using the wizards. This creates an AUTOMATIC ROW FETCH
TABLE NAME - EMP
Item Containing PRIMARY KEY - P2099_EMPNO
Primary key column - EMPNO
By default the automatic fetch has a ‘Process Error Message’ of ‘Unable to fetch row.’
2) Created a HTML region. Within this region add
text item P2099_FIND_EMPNO
Button GET_EMP to submit
Branch Modified the conditional branch created during button creation to set P2099_EMPNO with &P2099_FIND_EMPNO.
If I then run the page, enter an existing employee number into P2099_EMPNO and press the GET_EMP button the form is populated correctly. But if I enter an employee that does not exist then I get the oracle error ORA-01403: no data found and no form displayed but a message at the top of the page ‘Action Processed’.I was expecting a blank form to be displayed with the message ‘Unable to fetch row.’
I can work around this by making the automated fetch conditional so that it checks the row exists first. Modify the Fetch row from EMP automated fetch so that it is conditional
EXIST (SQL query returns at least one row)
select 'x'
from EMP
where EMPNO = :P2099_EMPNO
But this means that when the employee exists I must be fetching from the DB twice, once for the condition and then again for the actual row fetch.
Rather than the above work around is there something I can change so I don’t get the Oracle error? I’m now wondering if the automatic row fetch is only supposed to be used when linking a report to a form and that I should be writing the fetch process manually. The reason I haven’t at the moment is I’m trying to stick with the automatic wizard generation as much as I can.
Any ideas?
Thanks Pete

Hi Mike,
I've tried doing that but it doesn't seem to make any difference. If I turn debug on it shows below.
0.05: Computation point: AFTER_HEADER
0.05: Processing point: AFTER_HEADER
0.05: ...Process "Fetch Row from EMP": DML_FETCH_ROW (AFTER_HEADER) F|#OWNER#:EMP:P2099_EMPNO:EMPNO
0.05: Show ERROR page...
0.05: Performing rollback...
0.05: Processing point: AFTER_ERROR_HEADER
I don't really wan't the error page, either nothing with the form not being populated or a message at the top of the page.
Thanks Pete

Problem when using About Operator in Contains Query

Hi,
I'm new to Oracle and this forums too. I have a problem when using about operator in contains query.
I create a table with some records and then create a context index on 'name' column.
CREATE TABLE my_items (
id           NUMBER(10)      NOT NULL,
name         VARCHAR2(200)   NOT NULL,
description VARCHAR2(4000) NOT NULL,
price        NUMBER(7,2)     NOT NULL
ALTER TABLE my_items ADD (
CONSTRAINT my_items_pk PRIMARY KEY (id)
CREATE SEQUENCE my_items_seq;
INSERT INTO my_items VALUES(my_items_seq.nextval, 'Car', 'Car description', 1);
INSERT INTO my_items VALUES(my_items_seq.nextval, 'Train', 'Train description', 2);
INSERT INTO my_items VALUES(my_items_seq.nextval, 'Japan', 'Japan description', 3);
INSERT INTO my_items VALUES(my_items_seq.nextval, 'China', 'China description', 4);
COMMIT;
EXEC ctx_ddl.create_preference('english_lexer','basic_lexer');
EXEC ctx_ddl.set_attribute('english_lexer','index_themes','yes');
EXEC ctx_ddl.set_attribute('english_lexer','theme_language','english');
CREATE INDEX my_items_name_idx ON my_items(name) INDEXTYPE IS CTXSYS.CONTEXT PARAMETERS('lexer english_lexer');
EXEC ctx_ddl.sync_index('my_items_name_idx');Then I perform contains query to retrieve record :
SELECT count(*) FROM my_items WHERE contains(name, 'Japan', 1) > 0;
COUNT(*)
      1
SELECT count(*) FROM my_items WHERE contains(name, 'about(Japan)', 1) > 0;
COUNT(*)
      1But the problem is when I using ABOUT operator like in Oracle's English Knowledge Base Category Hierarchy it return 0
SELECT count(*) FROM my_items WHERE contains(name, 'about(Asia)', 1) > 0;
COUNT(*)
      0
SELECT count(*) FROM my_items WHERE contains(name, 'about(transportation)', 1) > 0;
COUNT(*)
      0I can't figure out what 's wrong in my query or in my index.
Any help will be appreciated.
Thanks,

Hello (and welcome),
You'd be best asking this question in the Oracle Text forum, here:

And by the way, it will help others to analyse if you put {noformat}{noformat} (lowercase code in curly brackets) before and after your code snippets.
Good luck!

Coercion problem when using Shared Variable

I have a curious coercion problem when using Shared Variables. I want to share the state of a State Machine, which is an enum saved as a control (typedef) called TYPE State (see attached). I create a shared variable called State and define it as a Custom Control, using the just-mentioned typedef. So far, so good. I've attached three simple VIs -- the first one, Init State, simply wires a constant to the input of the Shared Variable to initialize it -- the wired constant is, of course, defined by the typedef. However, the Get State and Set State, meant to wire an indicator (for reading the state) or control (for setting it), develop coercion dots when wired into the Shared Variable. Why? How do I get rid of the dot? [I suppose I could abandon my typedef and custom control, but the beauty of typedefs and custom controls is that it "enforces" rules, lets you use enums for clarity, keeps the code "honest", etc. -- I'd hate to give that up just to get rid of a dot!].
On a related note, the code seems to work. This is much too simplistic to do anything, but if you open Set State and Get State, set the state to anything, run it (it immediately stops, of course), then run Get State, you'll see the chosen state appear in the indicator. So it does appear to work. The "error" (coercion dot) may, I suppose, be a "bug" in Labview because it can't figure out the mapping of the (very simple!) Custom Control, but if so, I hope it gets fixed quickly!

Hello Bob,
I am also seeing this behavior, I will escalate this question to our LabVIEW developers and post again here no later than next Tuesday, November 27th as National Instruments will be closed for the remainder of this week.
If this issue does turn into a product suggestion, I would suspect the workaround would to live with the coersion dot for the time being.
Enjoy the holiday

NLS support problems when using AL32UTF8 in dads.conf

Hello,
Following a post by Joel Kallman, in one of the forum threads, about the mandatory use of AL32UTF8 in dads.conf, when running HTML DB v2.0, I changed my PlsqlNLSLanguage parameter accordingly.
Prior to the change, I experienced some problems when using non-English characters some application items appeared as gibberish when contained non-English characters, and the LIKE operator didn't perform as expected. After the change, it all seems to work OK, but now I have a different problem.
All the non-English characters in my HTML page source code appears as gibberish. On screen, at run time, everything display correctly, but the source code seems to be corrupted. It is very difficult, and very annoying to debug the pages that way. Is there a way to enjoy both worlds Using AL32UTF8 in the dads.conf, as required, and still getting a coherent HTML source code, containing non-English characters?
Thanks,
Arie.

TS2570 doesn't work, still the same problem when using Rapidweaver software. NOT with other software.

i tried everything in this article, but still have the same problem when using Rapidweaver software. NOT with other software. I am converting my iWeb site to Rapidweaver, whenever there is a calmer period in my office. I have 16 Gb RAM on my NEW iMac and have Parallels desktop, mail, safari, iWeb and Rapidweaver running simultanious.
I never have the problem if i don't use Rapidweaver, but after i have added several pages to Rapidweaver, the problem begins. my iMac won't start up. the only thing that works is re-installing Macos OS X 10.8. i tried even whiping the completeharddrive, and reinstalling with a complete new user, the same problem.
I had it on my previous iMac also, and bought a new one because i thought the problem was in the iMac first. i hadn't noticed it only happens with using rapidweaver.
i sent my complete rapidweaver project to the programmers from rapidweaver at Realmacsoftware, but they couldnt reproduce my problem, there macs started up without any problem.
i deleted all the rapidweaver addons and extra stacks, and started a complete new project.
saterday i had the problem again, after adding about 5 new pages to my rapidweaver site.
i think i have reinstalled Macos OS X 10.8.2 20 or 30 times by now
does anyone have a sollution?

Type '''about:support''' in the URL bar and hit Enter.
Scroll down almost to the bottom of that listing and see if you have '''user.js Preferences''' just above the '''''Graphics''''' category.
If you do have that, click on '''user.js file''' in this sentence. 
''Your profile folder contains a user.js file, which includes preferences that were not created by Firefox.''
Does that "different homepage" appear in that user.js file?

Performance problem when using CAPS LOCK piano input

Dear reader,
I'm very new to Logic and am running into a performance problem when using the CAPS LOCK-piano-keyboard for input of an instrument: when I'm not recording everything is fine and the program instantly responds on my keystrokes, but as soon as I go into record-mode there is sometimes a delay in the response-time (so I press a key and it takes up to half a second longer before the note is actually played).
Is there anything to do about this to improve performance (for example turning of certain features of the application), or should I never use the CAPS LOCK keyboard anyway and go straight for an external MIDI-keyboard?
Thanks and regards,
Tim Metz

Does your project have Audio tracks and just how heavy it is, how many tracks? Also, what kind of Software Instrument do you use?

Problem when using Javabeans in ADF?

Hi,

Please look at the following 2 classes :

private int age;
public Person(String name, int age, String city)
this.name = name;
this.age = age;
this.city = city;

     at javax.swing.JTable.prepareRenderer(JTable.java:3731)
     at javax.swing.plaf.basic.BasicTableUI.paintCell(BasicTableUI.java:1149)
     at javax.swing.plaf.basic.BasicTableUI.paintCells(BasicTableUI.java:1051)
     at javax.swing.plaf.basic.BasicTableUI.paint(BasicTableUI.java:974)
     So, I confused why? How to edit it properly?
     Thanks.

Hi, Frank
Thank you for your reply.
I am sorry for not explaining well. I mean that the getNames() works fine, but getPersons() does not. The only diferenece between them is the former is simple string and the latter is javabean, but when I made the PersonFactory as DataControl, I set the bean class Person for the getPersons()(list of persons) bean class.
I debuged the class, the exceptions raised when the table for getPersons() setModel() method called.
So, where is the problem?
Thanks.
