Maximum array length in javacard
hi all
i have a java class with 20 member variables.
member variables are array of bytes. i doesn't allocate
memory for this variables in class constructor,
memory for this variables is dynamically allocated
in my javacard applet (*runtime*).
i defined an array of this class in my applet( in applet constructor):
myclassArray = new myclass[MAX]
for ( short i =0; i < MAX; i++ )
myclassArray[i] = new myclass();myclass.java:
class myclass {
byte[] membervariable1;
setVar1( byte[] input) {
membervariable1 = input;
}if MAX >= 100 , i can't load applet on the card.
(error :conditions of use not satisfied)
why this problem occurs? my card is 32k and i doesn't allocate memory for myclass member variables in applet constructor;
maybe an array of class in javacard has a maximum value in its length. am i right?
thanks,
siavash

memory for this variables is dynamically allocated
in my javacard applet (*runtime*).Does not like it neither. If you look at your second code snippet, you're jusr re-referencing the pointer to another instance.

Maximum possible ARRAY LENGTH ?!?!
Hello All
How can I know (before allocating memory) what is the maximum possible array length. Does it depend on the JVM version or OS or something else ???
Please help !Thanx All !!!
I've moved to more "memory saving" algorithm, so there is no problem now :-))
But another 2 questions has poped up: I'm using a Vector object in a pretty long loop (millions of iterations) and once in a while accumulating some data (Long and Double objects) by adding them to the Vector.
1. What can be the maximum possible vector length ?
2. What's faster: using a Vector object or using a regular "long or double" array that should be reallocated as:
double[] arr = new double[****];
for(long i=0; i<Long.MAX_VALUE; i++)
// add new elem
double[] tmp = new double[arr.length+1];
System.arraycopy(arr, 0, tmp, 0, arr.length);
tmp[tmp.length] = newElem;
arr = tmp;

Hi,
running SQL*Loader (Release 8.1.7.2.1) causes an error "SQL*Loader-704: Internal error: Maximum record length must be <= [10000000]". This error occurs when SQLLoader is trying to load several thousand records into a database table. Each record is less than 250 bytes in length.
Any idea what could cause the problem?
Thanks in advance!

SQL*Loader-704: Internal error: Maximum record length must be <= [10000000]As a second guess, the terminator changes or goes missing at some point in the data file. If you are running on *NIX, try wc -l data_file_name. This will give a count of the number of lines (delimited by CHR(10) ) that are in the file. If this is not close to the number you expected, then that is your problem.
You could also try gradually working through the data file loading 100 records, then 200, then 300 etc. to see where it starts to fail.

"Maximum Session Length in Seconds" Not Working In Apex 3.2
Hello.
I am using Apex 3.2 and have noticed that pages are session timing out after just 10 minutes of inactivity. I am aware of the new security attributes "Maximum Session Length in Seconds" and "Maximum Session Idle Time in Seconds".
I asked our Apex admin and he reported that these attributes are set to 8 hours on the instance level. Within my own Apex application, these two attributes are not set at all. According to the popup help window associated
with these attributes, if they are not set, then there is no timeout at all that is enforced.
So, does anyone know why my application pages are session timing out after just 10 minutes of inactivity and users are forced to login again?
Thank you.
ElieScott,
Thank you for your help on this.
I've uploaded my Apex app called "Online Model", App ID 62063 in my workspace EEG on the Oracle hosted site apex.oracle.com.
Workspace = EEG
Username = [email protected]
Password = galaxy (I'll change the password after you're done helping me)
Orginally, this app had "Database Authentication" set. I changed this to "DAD Authentication" so that you can simply run it without having to login.
If I open up the app in developer mode and simply leave it alone for, say, 30 minutes and then click on the "developer bar" to see the definition of one of the pages, Apex instead prompts me to re-login again into Apex. I've not placed any values in any of the "Session Timeout" fields on any of the pages in this app.
When the same app is run as a user (that is, no "developer bar" appears at bottom of pages), again the page will time out after about 30 minutes of in-activity.
And as mentioned in my original posting, our Apex Admin has the "Administrator Timeout Session" field set to 8 hours.
The Apex 3.2 docs say that if no value is placed in these Timeout Session fields, then there is no timeout imposed.
Thank you for your help. It's much appreciated.

Maximum record length in internal table?
Is there a maximum record length in an internal table? Please note: My question is NOT related to table space. I'm referring only to the length of an individual record (A.K.A. row length).
I am using a work area to insert data into an internal table. Both the work area and internal table are defined by the same structure.
The structure has a total length of 672 bytes. For the sake of this discussion I'll point out that at the end of the structure, bytes 669, 670, 671, and 672 are four separate fields of 1 character each.
When viewing the work area record in the debugger I'm seeing all the fields and all the values. When viewing the internal table in the debugger after a record is inserted, the internal table ends with the field defined at Byte 670. The internal table does not include the two fields defined at Bytes 671 and 672.
Am I to assume from the above explanation that the length of a record ( A.K.A. row) in an internal table cannot exceed 670 bytes?
Thank you.Manish,
False alarm! While, technically, you didn't answer my question, your request for code ended up helping me answer my own question.
To provide you with some code I wrote a simple test program using the record layout referred to above, with a DO loop to put some records into the internal table, followed by a LOOP AT, with accompanying WRITE statements to display the contents of the internal table and demonstrate that the last two fields weren't being stored.
However, when I ran the test program, the last two fields were being displayed.
It was at that point, when stepping through the debugger that I noticed the scroll arrows above the last column of my internal table that allowed me to scroll to the right and see my final two fields.
Apparently, because of the large number of fields in my internal table I had reached the default display length of the debugger. While I was obviously aware of the scroll bar found at the bottom of the display, I had never worked with an internal table of that width in the past and hadn't even noticed the scroll arrows above the last column before.
Thanks for taking the time to respond helping me get to the solution. -
I am trying to deploy an RDL file (5MB) to SQL Azure Reporting server in South Central US using the deploy function in SQL Server Data Tools but facing the following error during deployment to Azure Reporting server.
"There was an exception running the extensions specified in the config file. ---> Maximum request length exceeded."
Is there any limit on the size of RDL files which can be deployed to Azure Reporting server? I have seen some online posts which talk about increasing the maxRequestLength in httpruntime of web.config in Reporting server. But in case of Azure Reporting server
how can be make modification to this configuration?
I have tried to upload it directly to SQL Azure Reporting server from the Management Portal --> Upload Report function which still resulted in error.
Thanks & Regards, DeepThanks for your question. Unfortunately we are in the process of deprecating SQL Reporting services. Full details are available at http://msdn.microsoft.com/en-us/library/gg430130.aspx

Maximum cable lengths for USB / FW / DVI & sVGA?
I've hunted around on the net and can't find any kind of definitive answer regarding maximum cable lengths for USB, Firewire 400/800 and DVI / sVGA monitors. Can anyone shed some light?
I'm about to shift my studio into a new room, and have the oppourtunity to stick my G5 and external drives into a corridor cupboard adjacent to where my studio is - in other words, noise free bliss! But....
...if I map out how far my computer monitors, keyboard and audio interface will be from the cupboard, and take into account the twists and turns involved in neat routing, I'm looking at a distance of about 10 meters. I need to know if any of these devices will be OK with such a long run of cable, and if not, if it's possible to achieve a good result using hubs or repeaters?
So, can anyone help me out with info on:
an Apogee Ensemble (Firewire 400)
an Apple keyboard (USB 2.0)
an LCD flatscreen (DVI)
and another LCD flatscreen (sVGA)
Many thanks!I was just researching the very same thing, though it does not sound like my studio setup will be as sweet as yours. Here are a few things I ran across:
FIREWIRE-
"The maximum cable length specified by the IEEE1394 standard is 4.5 meters. However, more recent tests have shown that certain high quality firewire cables can achieve longer lengths without significantly affecting transmission quality. Several manufacturers sell firewire cables longer than 5 meters (some up to 50 meters)."
~http://www.focusrite.com/answerbase/article.php?id=206
I found an example of a company who claims to sell a firewire cable of that length:

There is forum discussion on the topic I was reading yesterday:
http://www.everythingusb.com/forums/showthread.php?threadid=804
But don't go past the 11th post or so, they go off on another subject... the use of hubs & the words "active extension" in that post caught my eye. A quick google search came up with this site:
http://www.everythingusb.com/forums/showthread.php?threadid=804
There were a bunch sites with devices claiming to do this.
Finally I have this chart, which seems to support what what the articles say, without of course any other extension technology/solutions:
http://www.extron.com/company/article.aspx?id=dedigform10
I'm not making any claims at all about how true these sources are, I just have the same questions and decided to toss what I've been looking at into the discussion. Feel free anyone to jump in and tell me its all wrong - I'd love to hear whats right.

Windows service, error Maximum request length exceeded
What is causing this error, from the windows service?
There was an exception running the extensions specified in the config file. ---> Maximum request length exceededHi Nick,
Per my understanding you got this error "Maximum request length exceeded" about your reporting services, right?
It seems the issue is caused by the request reach the max length.
To solve the issue, please made the changes in web.config of both the Report Server and the Report Manager:
<httpRuntime executionTimeout = "9000" maxRequestLength=" 2097151" />
If the solution above does not help, please post the error logs of the Report Server. The error logs will help us more about troubleshooting and also provide us details information about what actions you are doing when causing this error.
We can get the logs from:
<Install Driver>:\Program Files\Microsoft SQL Server\MSSQL.<X>\Reporting Services\LogFiles
Please feel free to ask, if you have any more questions.

Maximum request length exceeded
I'm trying to upload a file to mobile services .NET backend, however I'm getting the error "Maximum request length exceeded". I tried increasing the limit in web.config file, but it only worked on the local version and still throws the error when
published to Azure.
As far as I understand the mobile services is ignoring the web.config file. So is there any other way to increase the upload limit?good news.. found a fix for this.
it's actually the same fix for file uploads that exceed the default 4mb set by IIS. however, the change needs to made to the report manager web.config file and not the report server web.config file. that's why it didn't work for me the first time.
here is an article that talks about it http://support.softartisans.com/kbview_825.aspx
if you have kept the default installation directory, the file you edit is:
C:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportManager\Web.config
Just add the maxRequestLength property here and set a size appropriate to you. Not to large to discourage DoS attacks.
The example below is 10mb
<httpRuntime executionTimeout="9000" maxRequestLength="10240"/>
hope it helps. -

Why arrays length is defined to be a field not a method in Java?
Why arrays length is defined to be a field not a method in Java?
TRANSLATE result USING R.
This statement replaces all characters in field result according to the substitution rule stored in field string R . R contains pairs of letters, where the first letter of each pair is replaced by the second letter.
in your case TRANSLATE result USING '#'.
menas '#' and ' ' space are 2 pair of characters.. and # is replaced by ' ' (space).
for better understanding..
Example:
DATA: T(10) VALUE 'AbCdEfGhIj',
STRING LIKE T,
RULE(20) VALUE 'AxbXCydYEzfZ'.
STRING = T.
TRANSLATE STRING USING RULE.
WRITE / STRING.
Output:

How to set array length correctly in this case
class RunJavaCode implements ActionListener{
public void actionPerformed(ActionEvent e){
try{
Process proc=Runtime.getRuntime().exec("java javaapp");
InputStream input=proc.getInputStream();
byte[] b=new byte[3000];
input.read(b);
String javaReport=new String(b);
input.close();
outputText.setText(javaReport);
}catch(IOException ioex){System.out.println("IOException is "+ioex);}
}how to set this array(byte[] b) length correctly? I mean this array length should not only save memory,but also enough to use('enough to use' mean that read outputed info from console to this byte array never overflow)Hi,
you cannot know in advance, how many bytes will be read. But the read-method returns the number of bytes actually read and this is important!
So at least you have to write: int r = input.read(b);
String javaReport=new String(b, 0, r); However, you still do not know, whether there is even more output available. You could however retrieve the data in a loop and append it e.g. to a StringBuffer, until EOF is encountered. -
How set maximum character length in Fxml
Hey can any body help me set Maximum character length in Fxml.
thanx in advanceI wrote my own TextField.
I can't give you the code right now, but it's easy to create it by yourself.
0 - create a private method that deletes any unwanted char/s: restoreRightLength();
1 - Add a listener on the textProperty of your TextField/TextArea that calls restoreRightLength() method.
2 - Override the following methods:
@Override
public void replaceText(int start, int end, String text) {
super.replaceText(start, end, text);
restoreRightLength();
@Override
public void replaceSelection(String text) {
super.replaceSelection(text);
restoreRightLength();
