How to get more than 256 bytes data

hello.
I use Schlumberger 32K Card�iJava Card 2.1�j.
Please tell me how to get more than 256 bytes data from the applet in the card!!
According to JCRE specification, need to use Get Response Command.
What is Get Response command?
Do I have to write processing of Get Response command to an applet?
Or JCRE processes Get Response command?
If knows, please tell me about!!
Thanks.

Thanks for your response!!
I understand that I have to write processing of Get Response command to an applet.
But case of Schlumberger 32K card, when host send Get Response command to an applet, card reply 6F-00!?
I'm investigating now, and it seems that response is returned before applet processes Get Response command(CLA = 00, INS = C0).
Do JCRE perform the process of Get Response command?

How to insert more than 32k xml data into oracle clob column

how to insert more than 32k xml data into oracle clob column.
xml data is coming from java front end
if we cannot use clob than what are the different options available

Are you facing any issue with my code?
String lateral size error will come when you try to insert the full xml in string format.
public static boolean writeCLOBData(String tableName, String id, String columnName, String strContents) throws DataAccessException{
boolean isUpdated = true;
Connection connection = null;
try {
connection = ConnectionManager.getConnection ();
//connection.setAutoCommit ( false );
PreparedStatement PREPARE_STATEMENT = null;
String sqlQuery = "UPDATE " + tableName + " SET " + columnName + " = ? WHERE ID =" + id;
PREPARE_STATEMENT = connection.prepareStatement ( sqlQuery );
// converting string to reader stream
Reader reader = new StringReader ( strContents );
PREPARE_STATEMENT.setClob ( 1, reader );
// return false after updating the clob data to DB
isUpdated = PREPARE_STATEMENT.execute ();
PREPARE_STATEMENT.close ();
} catch ( SQLException e ) {
e.printStackTrace ();
finally{
return isUpdated;
Try this JAVA code.

How to encrypt more than 117 bytes with RSA?

Hi there,
I am struggling to encrypt more than 117 bytes of data with a 1024 bit RSA key.
If I try to encrypt (write to my OutputStreamWriter) 118 Bytes ("A"s) or more, the file I am writing to is just empty and I get an exception whe trying to read it.
I know the encryptable bytes (blocksize) are related to the key length: blocksize = keylength / 8 -11
I also know RSA encryption of large files is discouraged, because it is like 100x slower than for instance AES and was originally only intended to exchange symmetric keys.
Still I need to be able to asymmetrically encrypt at least 5kb of Data.
I am out of ideas here and have no understanding of why the block size is limited (i know from hours of "googling" that it is limited as described above though).
So, I would be very glad If somebody could point out a way how I could encrypt more than 117 bytes (without using a longer key of course).

Good, it should be painful.

In this forum, 99.999% of the time this kind of claim is due to a lack of understanding of the role of public key cryptography.
I am out of ideas here and have no understanding of why the block size is limited (i know from hours of "googling" that it is limited as described above though).
It should not be difficult to break up the input into 117 byte chunks and encrypt each chunk through a newly initted cipher object. Of course you will have to be very careful in properly encoding the output. You might naively think that the output is always 128 bytes, but is that true? Might it be 127 bytes sometimes? Maybe even 126 bytes?

How to get more than 2 squares in Genius Mixes?

I have iTunes 9 and when I do Genius Mixes I get only 2 boxes when it says you get 12. How can I do this? Do I need to get more music?

Hi shraddha,
The Jet OLE DB provider reads a registry key to determine how many rows are to be read to guess the type of the source column. The registry setting is:
HKEY_LOCAL_MACHINE\Software\Microsoft\Jet\4.0\Engines\Excel\TypeGuessRows
Or
HKEY_LOCAL_MACHINE\SOFTWARE\wow6432node\microsoft\jet\4.0\engines\Excel\TypeGuessRows
By default, the value for this key is 8. Hence, the provider scans the first 8 rows of the source data to determine the data types for the columns. If any field looks like text and the length of data is more than 255 characters, the column is typed as a
memo field. So, if there is no data with a length greater than 255 characters in the first 8 rows of the source, Jet cannot accurately determine the nature of the data type. Therefore, values longer than 255 characters may be truncated or ignored.
To import data from a memo column, we must make sure that the memo column in at least one of the sampled rows contains a value longer than 255 characters. Or we can increase the number of rows sampled by the driver to include such a row by increasing the
value of TypeGuessRows. For more details, please refer to the following kb:

How to insert more than 4000 bytes in BLOB column

Hi all,
My oracle version is Oracle Database 11g Enterprise Edition Release 11.2.0.3.0.
I have checked in google and in this forum also, but did not find the answer.
When inserting into less than 4000 bytes, it is inserting without any issues. If i am inserting more than that, it is throwing
error like this ORA-01460: unimplemented or unreasonable conversion requested.
Can anybody guide me how to do this or link.
Thanks in advance.

Hi,
Thank you very much for your reply.
Before, I have not worked with BLOB column, so I don't know much about its using. Currently, I am using direct
insert statement only. Its a normal stored procedure written in a package. I am calling this SP with other columns and
with this BLOB column. I am able to insert into table, if the inserted file is less than 4000 bytes. If it is more than that,
I am getting that problem.
Thanks,
VenuSQL variables can only hold 4000 bytes.

External Hard Drive(ERROR CODE 0) .DMG Back Up Issues. How to get more than 4gbs in .DMG back ups.

I am currently using a my external hard drive for my late 2009 Mac Mini, my brothers MBP and my sisters HP laptop. I have a Western Digital My Passport 1T external Hard Drive to back up all are information. I formatted it to work on mac and pc and its on the "MS-DOS(FAT) setup at the momment. Im trying to back up DMG files from my HDD hard drive in my computer to the External Hard Drive to pass them onto my brother. I understand the whole part of me getting the "Error Code 0" where i can only put 4gbs of storage for that. I wanted to no is there a way for me to format my external hard drive for it to work on a Mac and a PC but for me to also transfer my .dmg files with more than 4gbs of that storage to my external hard drive?
p.s Im running on OSX 10.6.8 and the DMG files are alittle more than 4 gbs. From 5-10gbs. Thank you for all the replys. It helps me out and others in the Apple community out!

Hi, Steve. Your proposed procedure is just fine until you get to this point:
...reformat the WD to be Mac friendly *and reformat in FAT32* ...
Reformatting the newly-reformatted Mac-friendly drive as FAT32 will, as you say, simply put you back where you were before, but with your data on a different drive. Omit that step, and you'll have a Mac-friendly drive that you can copy your data back onto.
If you normally work with files exceeding 4GB in size, you won't want any hard drive in FAT32 format. If for some reason you'd like all your external drives in NTFS format, download and install the NTFS-3G driver, which will enable your Mac to read *and write to* that disk format.

How to get more than 4 coloured rows in a report depending on column values

Hi,
I've looked through the forum and found some stuff on mutli-coloured reports and found the link to http://htmldb.oracle.com/pls/otn/f?p=11933:7:557008579481721819
But I have several problems:
This shows how to get 3 colours, but it's easy to get up to 4 by just using the "Column Templates" in a new report template.
I don't understand where to put the snippets. It says to put them in "Row Templates" , "Before Rows" and "After Rows" but my report template page doesn't have these options! I've got "Column Templates" (4 of them), "Before Each Row" and "After Each Row".
Am I looking at a link for an old version?
What I want to do is set the row colour dependant on a column called "level" which is between 1 and 5.
Thanks

Hi Vikas,
It's almost perfect now. My only problem is that the pagination table is, for some reason, enclosed within the results table (I've used FireFox web developer's tools and checked the souce HTML to be sure of this). So, if I have a border at table level, it appears on the row containing the pagination.
I've had to remove table borders and put right borders on the table data cells, but I can't find a way to put left borders on the table rows, so I have a pretty table with 5 levels of colour, but no borders on the left-hand side.
Ideally I'd like to avoid having the pagination stuff within the results table, but I can't see how/where to put a </table> to sort this out!

How to get more than 1000 rec from Oracle?

Hi
i got this issue from 1 of my fnd.
can any one tell me how to over come this issue?
I need help in solving the issue
This is the oracle error coming when we try to export
the records to the excel sheet.
Macromedia][Oracle JDBC Driver][Oracle]ORA-01795:
maximum number of expressions in a list is 1000
This error is due to the limitation in oracle db list
query.
example:
select * from FEEDBACK_IN Where feedback_in.case_id
IN ( (param 1) , (param 2) , (param 3) , (param 4) ,
(param 5) , (param 6) , (param 7) , (param 8) , (param
9) , (param 10) , (param 11) , (param 12) , (param
13)……………………….(param
5000))
If the list exceeds 1000, we will get the following
error from the database. And there is a limitation in
oracle db to 1000.
We need to rewrite the query to avoid the list error
if the list exceeds more then 1000 records.

You must work with the guy who asked the same question
yesterday.

Opening Ports, how to get more than 10 slots

Hello. My Router is a WRT54GS running the latest firmware. I am trying to set my 360 up for Media Sharing using Windows Media Centre. To do this, I have to open up 5 ports in total. I already have 3 slots taken up by the PS3, two for IRC and 1 for utorrent. This leaves me with 4 slots left for ports. I know I can use a range to join some together, but as the PC, PS3 and 360 use different IP's, it means each need there own ports opening. Is there a way, if I need to in the future, to give me more slots to open more ports? Also, when trying to open a range of ports for the 360, some are the same as the PS3, and I get the error message "port overlap occurred! Please change your entry!" Does this mean, if a port is open for one IP, in this case its the PS3, and is 192.168.1.123, it'll also be open for another ip, the 360, which is .1.102 Hope I've made sense. Cheers Mike

One port can be forwarded to only one local IP address. And you can combine nearby port entries into a range which are for same local IP address.
