JNI and Cryptography Extension

I am using Visual C++ program that uses JNI. Within the code, I am using Java 2 Cryptography extension to do encrypting and decrypting.
I need help to understand the error message I have and what I need to do to fix this bug....
Thanks so much for any ideas
Exception in thread "main" java.lang.ExceptionInInitializersError: java.lang.SecurityException: Cannot set up certs for trusted CAs

at CmrCyrptography.encrypt(CmrCryptography.java:142)
at CmrTester.main(CmrTester.java.50)

After installing Jsdk 1.4 ,JRE 1.4 and JCE 1.2, it works fine. I have to change the library location too . And now all the error is gone

Hi,
I have noticed that I am also getting the same problem as you did earlier.
I have set the following in the classpath
Classpath="D:\ProdServerCode\src;D:\ProdServerCode\src\core\beans;D:\Pro
dServerCode\src\core\beans\activation.jar;D:\ProdServerCode\src\core\beans\jce1_
2_1.jar;D:\ProdServerCode\src\core\beans\junit.jar;D:\ProdServerCode\src\core\be
ans\ldapjdk.jar;D:\ProdServerCode\src\core\beans\mail.jar;D:\ProdServerCode\src\
core\beans\PerlTools.jar;D:\ProdServerCode\src\core\beans\servlets.jar;D:\ProdSe
rverCode\src\core\beans\sunjce_provider.jar"
My current version of Java is
C:\>java -version
java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)
-Please let me know what solved the problem for you. Currently I have
D:\ProdServerCode\src\core\beans\local_policy.jar
and
D:\ProdServerCode\src\core\beans\US_export_policy.jar in the same directory as
sunjce_provider.jar
jce1_2_1.jar
of which the latter 2 are in classpath and the former are not. Please let me know as to what do u mean by "I have to change the library location too " ....
Waiting for you reply in desperation,
Thanks,
Jameel.

Facelets and jsf-extensions problem.

I'm fairly certain I've run into a problem between facelets and jsf-extensions. I'm working with JSF 1.2 RI, Woodstock, Facelets 1.1.13, on Tomcat 6.
When trying to get Woodstock autoValidation to work I get a javascript error the "I has no properties". The error occurs in the com_sun_faces_ajax.js file in the jsf-extensions-dynamic-faces-0.1.jar (I've used both the RC4 and a build today ,10/18/07 from source with the same results). Here is the code snippet where it happens (with my comment).
var I = G.getElementsByTagName("components")[0];
var C = I.getElementsByTagName("render");
for(var F = 0; F < C.length; F++) {
In the second line there it looks like the variable I is null, but based on the post response below I don't know why.
The response from the post looks like this:
<partial-response><components><render id="PayableForm:vendorGci"><markup><![CDATA[{"valid":true,"id":"PayableForm:vendorGci"}]]></markup></render></components>
However the server side code (validation method) never gets executed. I'm willing to do some digging and debug work, but I'd need to be pointed in the right direction.
The following is more potentially useful code snippets.
Here is the textField code:
<w:form id="PayableForm">
<w:textField style="display:none;" />
<w:message for="vendorGci" />
<w:label id="vendorGciLabel" for="vendorGci" text="Vendor: " />
<w:textField id="vendorGci" autoValidate="true"
text="${vendorBean.searchGci}" maxlength="8" required="true"
validatorExpression="#{ vendorBean.validateVendor}" />
Here is the javascript in the page (the init function is called from the body: onLoad="setTimeout('init();', 0);" , this does happen):
<w:script type="text/javascript">
function VendorListener(){
function VendorNotify(props){
alert("VendorNotify called!"); <--------------- I never see this alert message
if ( props.id != "PayableForm:vendorGci") { return; }
var field = document.getElementById("PayableForm:vendorGciLabel");
field.setProps({
valid: props.valid
VendorListener.prototype.notify = VendorNotify;
function initAccountRows(){
var table = document.getElementById("PayableForm:vendorAccountTable");
table.initAllRows();
function init(){
initAccountRows();
var listener = new VendorListener();
dojo.subscribe(
webui.suntheme.widget.textField.event.validation.endTopic ,
listener, listener.notify);
Here is the validator method. It currently doesn't do anything, just trying to get something to work. I never see the output, and I never hit the breakpoint in the method.
public void validateVendor(FacesContext context, UIComponent comp, Object value){
System.out.println("**********************************");
System.out.println("validateVendor called");
System.out.println(value);
System.out.println("**********************************");
}

Actually I don't need a global variable. I need to refer in my included template the actual backing bean used in the current page. As all my backing bean extends a abstract class I could bind my component to a property of the current backing bean, no matters which one. Just like a polymorphic call but without the parameter. Let's imagine I could get this object of the facesContext object I would be able to do:
<rich:datascroller renderIfSinglePage="false" align="right" for="listagem" maxPages="12" fastStep="10"
pageIndexVar="pageIndex" pagesVar="pages" stepControls="show" fastControls="hide" boundaryControls="show"
inactiveStyleClass="paginacaoInativa" selectedStyleClass="paginacaoSelecionada"
styleClass="paginacao" tableStyleClass="paginacaoTabela"
binding="#{facesContext.currentBackingbean.formDataScroller}" id="paginacao">
Instead of pass the backing bean to the ui:param of this template... Dou you get the point?

JVM Crash When Using JNI and COM

I'm trying to call a DLL compiled from VB6 source code that I do not have access to. The VB6 code simply retrieves data from a DB2 database using ADO and my client code grabs that data and marshals it to my Java code. I'm attempting to achieve this using JNI and COM (without a third-party bridge). It works 75% of the time, but the other 25% of the time, the JVM crashes with the usual Hotspot crash log containing an access violation exception. However, I don't know what in my C++ code (VC++ 8) could be causing this except for passing a "wild" pointer to the code lying underneath the COM object interface. If that is the case, I don't know how I am doing that.
The Java code that is calling my native method is running on Tomcat 5.5.25 and just to be safe, I am not allowing multiple threads to concurrently call the method in my JNI DLL (though I realize that this will kill performance). Once I can get past this problem, I'll do the COM interfacing on a worker thread in my native code so I don't screw up CoInitialize and CoUninitialize calls in the case the same thread is concurrently executing multiple calls to my native code.
I've noticed that in most cases, the JVM crashes during my call to the pClsAccount->OpenConnection method. However, my DLL isn't what is listed on the top of the call stack, which is why I suspect the passing of a wild pointer, though I'm just taking a guess at that. Does anyone have an idea as to what's going on ?

C# compiling error: 'System.Array' does not contain a definition for 'Select' and no extension method 'Select' accepting a first argument of type 'System.Array' could be found (are you missing a using directive or an assembly reference?)

Hello experts,
I'm totally new to C#. I'm trying to modify existing code to automatically rename a file if exists. I found a solution online as follows:
string[] allFiles = Directory.GetFiles(folderPath).Select(filename => Path.GetFileNameWithoutExtension(filename)).ToArray();
string tempFileName = fileName;
int count = 1;
while (allFiles.Contains(tempFileName ))
tempFileName = String.Format("{0} ({1})", fileName, count++);
output = Path.Combine(folderPath, tempFileName );
string fullPath=output + ".xml";
However, it gives the following compilation errors
for the Select and Contain methods respectively.:
'System.Array' does not contain a definition for 'Select' and no extension method 'Select' accepting a first argument of type 'System.Array' could be found
(are you missing a using directive or an assembly reference?)
'System.Array' does not contain a definition for 'Contains' and no extension method 'Contains' accepting a first argument of type 'System.Array' could be
found (are you missing a using directive or an assembly reference?)
I googled on these errors, and people suggested to add using System.Linq;
I did, but the errors persist.
Any help and information is greatly appreciated.
P. S. Here are the using clauses I have:
using System;
using System.Data;
using System.Windows.Forms;
using System.IO;
using System.Collections.Generic;
using System.Text;
using System.Linq;

Besides your issue with System.Core, you also have a problem with the logic of our code, particularly your variables. It is confusing what your variables represent. You have an infinite loop, so the last section of code is never reached. Take a look
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
namespace consAppFileManipulation
class Program
static void Main(string[] args)
string fullPath = @"c:\temp\trace.log";
string folderPath = @"c:\temp\";
string fileName = "trace.log";
string output = "";
string fileNameOnly = Path.GetFileNameWithoutExtension(fullPath);
string extension = Path.GetExtension(fullPath);
string path = Path.GetDirectoryName(fullPath);
string newFullPath = fullPath;
string[] allFiles = Directory.GetFiles(folderPath).Select(filename => Path.GetFileNameWithoutExtension(filename)).ToArray();
string tempFileName = fileName;
int count = 1;
//THIS IS AN INFINITE LOOP
while (allFiles.Contains(fileNameOnly))
tempFileName = String.Format("{0} ({1})", fileName, count++);
//THIS CODE IS NEVER REACHED
output = Path.Combine(folderPath, tempFileName);
fullPath = output + ".xml";
//string fullPath = output + ".xml";
UML, then code

How to install Thunderbird and Lightning Extension to StarOffice 9

I just purchased StarOffice 9, read the entire documentation, including the "Getting Started" PDF file. Looked all over Sun.com and nowhere can I find how to install the Thunderbird and Lightning extensions touted as being available for StarOffice 9. Thanks for any help.
LarryMcJ

Hi Larry,
Thunderbird and the extension Lightning are two independant parts, and with StarOffice 9 deluxe available.
If u have StarOffice 9 u should download -free- the email and calendar client from
the Mozilla Thunderbird page and Mozilla Lightning page
after downloaded Lightning 0.9 !!
open thunderbird -->options --> addons chose the file downloaded, click ok, and install
Now u can manage tasks and so on in your thunderbird, but independant of StarOffice apps !!
greetings,

MacBook Pro Exchange and Repair Extension Programs

Hi:
I have a MacBook Pro Early 2008, and I think my laptop problem is the Nvidia Card. My laptop doesn't start. I can't hear the chime at startup, but I can hear the DVD and the HD spinning, and the fans working. I phoned the nearest Apple mervice and they said me that it is imperative that my computer is running so they can perform the test that determines whether the problem of my computer is covered by the Exchange and Repair Extension Programs "or distorted video no video issues". I have told them that's impossible, because the logic board defect causes a impossibility to boot the laptop.
Can anyone tell me if it's true that the Apple Service says to me? How they intend I start my laptop?
Thanks in advance.
(Sorry for my english)

Thanks a lot for your reply.
But...
Why are you so sure that the Nvidia failure does not prevent the computer start-up. The laptop has worked flawlessly so far.
In some forums I read that the cause of the boot failure is just the defective nvidia board. First I had some screen flickering problems, and the latest problems are screen blackouts, this seems that the boot failure is the last symptom of a defective board.
In any case, I find it's a kind of surreal nightmare that Apple launch a replacement program, and deny coverage for units that have been rendered useless because the problem that justifies the replacement program. Doesn't have Apple the serial numbers of the units that can be affected by a problem that Nvidia recognize?
Anyway, thanks again

Java 1.5 JNI and C++ exception

Hello, All
I've troubles with handling C++ exceptions using JNI and shared library. I'm using Java 1.5_06, RedHat 7.3 and JBoss 4.0.5
From Java class I call JNI a method in my shared library(libx.so) which calls a method in other shared library(liby.so). Liby.so uses Xerces library. During parsing process an exception occurs. But according to Xerces sources it's a normal behavior and should be caught. But instead I've got SIGNABRT in JVM and a core dump will created. What's wrong? Backtrace shows similar something:
XXXXX __default_terminate() ....
XXXXX __terminate() ....
XXXXX __throws
XXXXX C++ method ..
XXXXX.....
XXXXX.....
XXXXX JNI methodI found similar bugs reports in the forum. But they says about Java 1.4 version and according to bugs descriptions it should be already fixed.

The question is closed. The root cause was incorrect building of shared library.

Flash Builder 4.6 and CS Extension Builder 1.5

I have downloaded Flash Builder 4.6 and CS Extension Builder 1.5 and we have one big problem related to design mode.
Actually when we switch to design the visual editor is completely black!
Thanks.
Diego

It's not going to be fixed.
The only version of FB where design mode really works is 4.0. Even in 4.5, it's very fragile for Flex 3. (Flex 4 should work fine.)
Yes. I use EB 1.5 all the time. The lack of a working Design Mode is annoying and makes devlopment somewhat less efficient, but it's not a show-stopper...

X11 and xlib extensions

I'm having 'issues' using X11 on my Powerbook. I connect to work with a VPN. Once on the network I ssh to one of the servers.
I can start X11 apps and the gui's show up on my mac as I expect (xeyes, nedit, etc). The problem is when I start some apps I get the following error(s) -
Xlib: extension "GLX" missing on display "localhost:12.0".
Xlib: extension "RENDER" missing on display "localhost:12.0"
Kate gives both errors. It does start, but its really slow running. Other apps only give one error.
What do they mean? Is there a different X server other than Apple's that will support those extensions?
Thanks,
Aaron R>

X11 servers support runtime extensions, which are just what they sound like...external files that provide additional features and functions. If you run a program that wants to use the functionality of a certain extension and that extension is not present (or fails to load, or whatever) the program can either abort entirely, or else try to run but avoid using the enhancement (maybe a slower internal function instead of an efficient server extension?). Apple's X11 does not have every possible extension, but I thought it did have those two, but maybe they don't work load properly via the number of hoops your jumping through from remote program to local display? Try running 'xdpyinfo' from a local xterm to see what extensions are available, and then run it in an xterm on the remote machine to see if things are missing?

Assign the name of a file and its extension when using DESTYPE=MAIL

Hello,
I've developed a report running Oracle Reports 10g that is being emailed to a user. I would like to specify the name of the file and it's extension that is attached. Are there variables or parameters in Oracle Reports that I can use to accomplish this?
It looks like by default that the file name is using the Name value found in the Property Inspector for the report. I have not been able to find a way to re-assign this value with a value from either the input or select values in the data model.
Will Oracle Reports 10g allow me to define the name of the file and the extension?
Any help or direction would be greatly appreciated.
Thanks in advance

Thank you for the quick reply and information. I almost thought you had solved my problem until I found out that distribution and bursting do not support delimited and spreadsheet output. One of the two files I need to email has a desformat of SPREADSHEET.
Is there any other way to manipulate the file name and extension when using destype of MAIL?

Why does Firefox disable the Uninstall button on incompatible and disabled extensions (which should be removed)?

I guess I'm just OCD because I don't want to see a bunch of incompatible and disabled extensions on my list but I can't be the only person who would like to remove them. It seems the obvious choice ... but it is unavailable. Why?

Please don't dodge the question. People have normal adds-ons and extentions that when become incomparable are greyed out and there is no way to uninstall it. Mine is Java at this time. Mine is an extension. I haven't had this enabled since 7 came out apparently I don't need it. So I would like to save space and take the darn thing off the computer. But I can't find a way. Can you please help me? thanks

Why is there no updates to the firefox throttle add-ons ? Is there an alternative? throttle is Bandwidth utilization throttling and monitoring extension for Firefox

Why is there no updates to the firefox throttle add-ons ? Is there an alternative? throttle is Bandwidth utilization throttling and monitoring extension for Firefox

Well, it's probably one of two things: either the awesome dude(tte) who developed this awesome extension was tired of updating or the changes in FFox software architecture carried out between version 3.x and 4+ created challenges that were too difficult for him to surmount or a combination of both. Honestly, I love Mozilla but I think they dropped the ball on the throttle issue. It's such an obvious and necessary function and it's so easy to implement. They should have included it a long time ago as in built feature. And, if you are browsing and looking at this post and you agree. Add a suggestion in mozilla.org. The more of us asking for this function, the better.
Meanwhile, I have the following solution for you:
Solution 0.6.9.23.11 (DIY Version of my Solution ):
Setting Up a Separate Portable Firefox 3.6.x that runs independently of and simultaneously to your latest version of Firefox
Get FireFox Portable 3.6.24:
http://portableapps.com/apps/internet/firefox_portable/localization#legacy36
It's a portable app, meaning that it's got all it's profiles and preference and application files in the same directory. It won't compete with your current installation of Firefox, has it's own separate extension folder etc...
Get Firefox Throttle 1.1.6
http://firefox-throttle.en.softonic.com/ (I couldn't find it in the official mozilla site)
It will be flagged as incompatible with even that old version of firefox (but it isn't). You just need to turn off compatibility checking. You can do that with this extension:
https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/?src=search
If you have Bookmarks you want to port to the portable (bad pun intend), backup them up to bookmarks.json file on your desktop and import them to the portable version. You can export/import more stuff using FEBE addon but that's a whole world of headaches if you don't your doing.
Many of your extensions favourites extensions will no longer work on FFox 3.6.x but if, in that same addon's page, you look around until you find a link to previous versions of the addon, you will notice that the compatibility info is right below the version numbers. Just download and install the latest version that is compatible with you 3.6.x....
Voila mon ami! Your FFox 3.6 portable has just become your own private Download Mule whom you can throttle to your hearts content (ever throttle a real Mule??? I wouldn't try it, personally...) Do your regular browsing in another (unthrottled) browser and do your big downloads in the Mule...
If you want to keep using your brand spanking new Firefox for other types of browsing while using this portable Mule edition for the downloads, just add -p -no-remote to the shortcut leading to your Firefox Portable Mule edition.
For example, my taskbar shortcut to my Firefox Portable is:
""C:\Program Files (x86)\FirefoxPortableLegacy36\FirefoxPortable.exe"
I just changed it to:
"C:\Program Files (x86)\FirefoxPortableLegacy36\FirefoxPortable.exe" -p -no-remote
This will make it occupy it's own independent instance and I can use the both my Firefox Nightly and the Firefox Portable editions at the same time (each one, using a different profile ie. extensions, cookies, password, cache etc).
If you're on Linux, you can just run this on Wine and set the Windows Version to Windows 2000 in the Wine config,

Solution 0.6.9.23.11 (Non-DIY Version of my Solution):
Download my preconfigured but SWAGGED-THE-HECK-UP PortableFirefox 3.6
Having realized that some of you may find the above to be daunting. I took my own customize firefox portable, took out all my data and compressed the folder (it's portable, so it'll run as soon as you unzip it).
Here is a screenshot:
http://www.mediafire.com/?o95nkwo8y6q535j
Here is the download link:
http://www.mediafire.com/?xdw87ivf3184u2s
Don't forget to modify your Start/Taskbar shortcuts:
"C:\wherever you decide to put it\FirefoxPortableLegacy36-Swagged-UP!\FirefoxPortable.exe"
I just changed it to:
"C:\wherever you decide to put it\FirefoxPortableLegacy36-Swagged-UP!\FirefoxPortable.exe" -p -no-remote

JNI and Out of Memory errors

Hi,
At my job, we seem to have a memory leak related to JNI. We know we
have a memory leak because we keep getting Out of Memory errors even
after increasing the maximum heap size to more than 256 megs. And we
know that this is the application that is eating up all the system
memory.
We are running under Windows 2000, with both JDK 1.3.0 and JDK 1.4.1.
We tried looking at the problem under JProbe, but it shows a stable
Java heap (no problems, except that the Windows task manager shows it
growing and growing...)
I tried a strip down version, where I set the max heap size to 1 Meg,
and print out the total memory, memory used, and maximum memory used at
a 5 sec interval.
Memory used = Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory().
Well, I let that strip down version running for about a day. The
maximum memory used has stabilized to about 1.1 Meg, and has not
increased. The current memory used increases until it gets to some
threshold, then it decreases again. However, the Windows task manager
shows the memory increasing -- and currently it is at 245 Megs!
In the lab, the behavior we see with the Windows task manager is as
follows:
1. Total memory used in the system increases until some threshold.
2. Then it goes back down by about 100 Megs.
3. This cycle continues, but at each cycle the memory goes back down
less and less, until the app crashes.
Now, our theory is that JNI is consuming all this memory (maybe we are
using JNI wrong). That's the only explanation we can come up with to
explain what we have seen (Java showing an OK heap, but the task
manager showing it growing, until crashing).
Does that make sense? Can the new operator throw an Out of Memory
error if the system does not have enough memory to give it, even if
there is still free heap space as far as the Runtime object is
concerned? Does the Runtime object figures objects allocated through
JNI methods into the heap used space?
Note that I know the task manager is not a reliable indicator.
However, I don't think a Java app is supposed to runaway with system
memory -- the problem is not simply that the Java app is consuming too
much memory, but that it seems to always want more memory. Besides, we
do get the Out of Memory error.
Thanks for your help,
Nicolas Rivera

Hi,
there are two sources of memory leakage in JNI:
- regular leaks in c/c++ code;
- not released local/global references of java objects in JNI.
I think that the first issue in not a problem for you. The second is more complex. In your JNI code you should check
- how many local references alive you keep in your code as their number is restricted (about 16 and can be enlarged). The good style is not to store local references but keep only global.
- any local reference accepted from java call in JNI are released by JVM. You should release local references you created in JNI and also global references.
- do not use a large number of java object references. Each new reference gets new memory in JVM. Try to reuse refences.
I guess that is your problem.

i suggest filing a feature request through the bug tracker.
As for why such features may not be compiled in is that whoever maintains the package may have never had the need to have such features in php or experienced any issue because of it. You will experience this with many distros so I suggest not getting accusatory and simply request the feature through the proper channels.
Each persons needs and experience are different and that is why developers write their code to encompass as many features as their users request. How robust a package needs to be in arch is up to people like you giving the crucial feedback.
(btw i don't see why your request would not be granted. I suggest the feature request though because i know the maintainer of the PHP package is not a frequent visitor to this forum but he will get your request if you make to the bug tracker)
