Clearing byte array field

Hello all,
I've encountered a problem in trying to reset fields in my applets which I just can't figure out, I'd appreciate some help with it.
Basically I have a method in a base class for my applets which sets the fields in my card. This works fine, the problem I have is when I tried to alter this method so that if the command APDU received does not contain the data field(i.e. a Case 2 APDU, 5 bytes long), then the designated byte array is set to null. The code is shown below.
// Method in applet
public void setSurname(APDU apdu) {
surname = setByteArrayVariable(apdu);
// Method in applets' base class
public byte[] setByteArrayVariable(APDU apdu) {
byte[] apduBuffer = apdu.getBuffer();
short len = apduBuffer[ISO7816.OFFSET_LC];
byte[] arrayname = null;
if(len != (short)0){
arrayname = new byte[len];
// copy buffer data into byte[]
short bytesRead = apdu.setIncomingAndReceive();
short Offset = (short)0;
while (bytesRead > 0) {
Util.arrayCopy(apduBuffer, ISO7816.OFFSET_CDATA, arrayname, Offset, bytesRead);
Offset += bytesRead;
bytesRead = apdu.receiveBytes(ISO7816.OFFSET_CDATA);
return arrayname;
What happens when I send the Case 2 APDU to the applet is that the CLA and INS bytes direct the apdu to the proper method to set the field and the byte array is set to null(success). At this point I expect the JCRE to return the sw 9000, however what actually happens is the applet throws the ISOException defined in the default case of the process method. Also I checked this method in the gemplus simulator and it works as expected, its only when I tried it in a GXP211_PK_IS card that the problem occurred, I've asked the Gemplus support about this but as yet have not heard anything in response. I cannot explain why this is happening, has anybody got any suggestions? Thanks,
Tony

The status word which is returned is 6D00(INS not supported), as this is what I throw in the process method when the switch doesn't match the INS byte with any of the cases. This is where my confusion comes from, if the method is called(through matching the CLA and INS bytes) how is it that after the method is completed(successfully, as the field is set to null) that the exception is thrown form the process method as if the method wasn't found? I have a workaround whereby instead of throwing the 6D00 I throw the ISO7816.SW_NO_ERROR in the default case of my process method, this can only be a temporary workaround though!!
I'm guessing that you check for surname != null later on ? I do check this but only when I'm trying to retrieve the surname from the card, basically, if(surname == null)ISOException.throwIt(ISO7816.SW_FILE_NOT_FOUND);
Doesn't sound like thats what you're getting at though??
(Will sort out the memory allocation, cheers.)
TIA for any help you can provide, leaving now for the day but hoping to hear from you tomorrow :)

JDO : how to map a byte array field correctly

Could someone please provide an example on how to correctly map a byte array field in a PCClass.
The field should be mapped to a BLOB field in my Dictionary project.
The checker keeps throwing errors during the enhancement process. Tried all sorts of combinations of xml in my jdo and map file (using the dtd) but I still haven't found the solution. The compilation works fine though, it is only the checker that complains.

How to clear byte array

Hi, here are the codes
byte[] buffer = new byte[1000];
// use the buffer for something else
then How can I clear the content of this buffer,
so I can use it for TCP/IP datainstream again
int result=in.read(buffer);
Thank you very much.

Thank you very much. You shouldn't have to clear the buffer. The read() method returns the number of bytes read, so you know not to read past that point in the buffer.
As an example, here is some code that reads from one stream and writes to another. Note that I use the 3 parameter version of write() to make sure I only use the part of the buffer that actually got filled by the last call to read(). In the following, os is an OutputStream and is is an InputStream.
                    byte[] buf = new byte[1024];
                    int count = 0;
                    while((count=is.read(buf))!=-1) {
                      os.write(buf, 0, count);
                    }

How do i clear a byte array?

Hi. I'm reading a different chunk of data each time and therefore need to clear the byte array before I go to the next chunk. I've seen
other ways through a buffer but that is too complicated for me to understand. Can u please tell me if there is a simple method in the API to clear it?
Thank you!!

well i thought it was, but i'm using the matcher class to read the data and storing it in a byte array of size 512 and it seems that when i convert it into a string, the previous data is still there if i read something less than 512

Convert XML data to byte array...

Hello All,
In my application, i have an XML file and the corresponding XSD file. This XML file is having some date, which i want to convert into an byte[] and then save it in a file.
How i can convert the XML data in the byte[]? Here as an example of the xml file and the byte[] data which i want to save in a file.
<?xml version="1.0" encoding="utf-8"?>
<HeadersInfo>
<header>
<id>0</id>
<Name>H1</Name>
</header>
<header>
<id>1</id>
<Name>H2</Name>
</header>
</HeasersInfo>
In the above example 'id' field is of type 'uint' and 'name' field is of type 'string' with max length of '5'. So in this case my byte array should be as shown below:
00 00 00 01 48 31 00 00 00
00 00 00 02 48 32 00 00 00
Here underlines values are for the 'id' parameter where as values in bold are for 'Name' parameter for all the header values in sequence. Name parameter is null (0x00) padded.
Thanks in advance,
IamHuM

Hi,
the following example extract the id, name values using LINQ To Xml and writes it to a memory stream using a binary writer and returns the result as a byte array:
internal static byte[] GetXmlAsByteArray()
var document = XDocument.Parse("<HeadersInfo>"
+ " <header><id>1</id><Name>H1</Name></header>"
+ " <header><id>2</id><Name>H2</Name></header>"
// additional testing
+ " <header><id>32767</id><Name>H1234</Name></header>"
+ " <header><id>305419896</id><Name>H56789</Name></header>"
+ "</HeadersInfo>");
const int NameLength = 5; // Max length for a name
byte[] zeroBytes = new byte[NameLength]; // Helper to fill name
using (var ms = new MemoryStream())
using (var writer = new BinaryWriter(ms))
// write each header
foreach (var header in document.Root.Elements("header"))
int id = (int)header.Element("id");
string name = (string)header.Element("Name");
byte[] nameBytes = System.Text.Encoding.UTF8.GetBytes(name);
Console.WriteLine("id: {0}, Name: {1}", id, name);
// Write id
writer.Write(GetUIntBytes((uint)id));
// Write name NameLength (5) max, otherwise padded
if (nameBytes.Length > NameLength)
writer.Write(nameBytes, 0, NameLength);
else
writer.Write(nameBytes, 0, nameBytes.Length);
if (nameBytes.Length < NameLength)
writer.Write(zeroBytes, 0, NameLength - nameBytes.Length);
byte[] result = ms.ToArray();
// dump array
foreach (var value in result)
Console.Write("{0:X2} ", value);
Console.WriteLine();
return result;
public static byte[] GetUIntBytes(uint value)
if (BitConverter.IsLittleEndian)
// swap bytes
value = ((value & 0x00ff) << 24)
| ((value & 0xff00) << 8)
| ((value & 0x00ff0000) >> 8)
| ((value & 0xff000000) >> 24);
return BitConverter.GetBytes(value);
For a general purpose solution you should create a class and split the example into separate methods to extract the data and write the values (integers, strings).

How do I get a byte array from an object passed into the JNI?

This is what my java code looks like:
public class streamedData
protected byte[] m_value = null;
public byte[] getByteArray ()
return m_value;
/* code not pertaining to this question snipped. */
jclass streamedDataClass = env->GetObjectClass(jstreamedData);
// Get methodIDs for the various NPKI_Extension methods
value = env->GetMethodID(streamedDataClass, "getByteArray", "()[B");
lstreamedData->value = (unsigned char *)malloc (lstreamedData->length);
if (lstreamedData->value == NULL)
return INSUFFICIENT_MEMORY;
memset (lstreamedData->value, 0, lstreamedData->length);
memcpy (lstreamedData->value, env->CallByteMethodA(streamedDataClass, value, NULL), lstreamedData->length);
This is not working.
My question is, how do I get a copy of or read m_value in the JNI layer? Do I have to make the byte array public and access it as a field ID?
Any help would be appreciated. Why oh why can't there be a CallByteArrayMethod????

My question is, how do I get a copy of or read m_value in the JNI layer? Do I have to make the byte array public and access it as a field ID?
You can retrieve a handle to the byte array, through a method call, as you're doing now, or by directly accessing it through GetFieldID.
In the case of the method call, you'll want to do:jmethodID getByteArrayMethod = env->GetMethodID(streamedDataClass, "getByteArray", "()[B");
jbyteArray byteArray = static_cast<jbyteArray>( env->CallObjectMethod( jstreamedData, getByteArrayMethod ) );In the case of field access, you can do:jfieldID m_valueFieldID = env->GetFieldID( streamedDataClass, "m_value", "[B" );
jbyteArray byteArray = static_cast<jbyteArray>( env->GetObjectField( jstreamedData, m_valueFieldID ) );Once you have byteArray, you need to access it using the array operations:lstreamedData->value = env->GetByteArrayElements( byteArray, 0 );
// Do what you want to do, then release the array
env->ReleaseByteArrayElements( byteArray, lstreamedData->value, 0 );As always, Jace, http://jace.reyelts.com/jace, makes this easier. For example,void printByteArray( jobject jstreamedData ) {
streamedData data( jstreamedData );
JArray<JByte> byteArray = streamedData.m_value();
for ( int i = 0; i < byteArray.length(); ++i ) {
cout << byteArray[ i ];

Reading camera's DevieInfo NOT in byte array?!

Hello everyone,
I am struggling to retrieve a DeviceInfo dataset from a camera that I have.
At first I thought it will be easy, something like:
OSErr err;
ICACopyObjectPropertyDictionaryPB dictPB = {};
NSDictionary* deviceDict = NULL;
dictPB.object = [[[self leCamera] cameraID] unsignedLongValue];
dictPB.theDict = (CFDictionaryRef*)(&deviceDict);
err = ICACopyObjectPropertyDictionary(&dictPB, NULL);
if (err == noErr)
[[self window] setTitle: [deviceDict objectForKey: @"device firmware"]];
The problem is the firmware version is not in the dictionary that I get with
the ICACopyObjectPropertyDictionary command and yes I have the right
deviceID(cameraID).
The second thing that I have tried is to retrieve the object with PTPPassThru
command which works and the firmaware is there but I get like 256 bytes
buffer which is really tedious to work with(the problem is that there are
variable fields in this buffer and I have to read their size every time in order
to jump over certain number of bytes in which I am not interested.).
So the questions that occur to me are, am I the first one who needs to do
such a thing? I guess not. How did the guys before me accomplish it? Is
the PTPPassThru command and the buffer processing the only way to go
or is there some ICA function returning a dictionary with what I need.
Any help or insights will be greatly appreciated!
Best regards
artOf...

I took the hard way and retrieved the information that I needed as byte array...
The application is functioning now, anyway if anyone has some suggestions
they are all welcome.

Problem in reading/writing byte array in Access database! PLEASE HELP!!

Hi,
I want to store a signature, which is in form of a byte array, in OLE Object field in MS Access database. I want then to retrieve this signature and verify it. The problem is that the retrieved byte array is not identical to the stored (original) one, and therefore, verifying the signature fails! Any help would be much appreciated as I can't proceed in my project without solving this problem. Here is the code to do the above mentioned functionality:
//This part stores the signature (VT) in the table TTPTrans
try
{ con = connect();
ps = con.prepareStatement("UPDATE TTPTrans SET VT = ?, SigVT = ? WHERE TransID = ?");
ps.setBinaryStream(1, new ByteArrayInputStream(vt), vt.length);
ps.setBinaryStream(2, new ByteArrayInputStream(sigvt), sigvt.length);
ps.setString(3, tID);
ps.executeUpdate();
ps.close();
con.close();
catch (Exception e)
{ System.err.println(e.getMessage());
e.printStackTrace();
//This part retrive the signature from the table in the byte array o1:
ResultSet result;
byte[] o1 = null;
byte[] o2 = null;
try
{ con = connect();
Statement statement = con.createStatement();
result = statement.executeQuery("SELECT VT, SigVT" +
" FROM TTPTrans" +
" WHERE TransID = " + "'" +
transID + "'");
while (result.next()) {
o1 = result.getBytes("VT");
o2 = result.getBytes("SigVT");
statement.close();
con.close();
catch(Exception e)
{ System.err.println(e.getMessage());
e.printStackTrace();
}

In the following code, I use a ASN1SDSSSignature class, which is a subclass that I created from the Siganture class, to create and verify an SDSS signature. The ASN1SDSSSignature has two ASN1Integer class variables:
signcryption = token.getSigncryption();
sig.initVerify(ttpCert);
sig.update(receivedVT);
boolean verified = sig.verify(receivedSigVT);
if(!verified)
System.err.println("TTP signatire on received token invalid. ");
notify()
return;
Where receivedVT and receivedSigVT are the byte arrays retrieved from th database. The following exception is thrown when I run the application:
ASN1 type mismatch!
Expected: codec.asn1.ASN1Integer
In: ASN1SDSSSignature
At index 0
Got tag: 4 and Class: 0
I hope this would clarify the situation and thanks in advance for any comments you may post.

GP 2.1.1, A.2 GlobalPlatform on a Java Card, Installation:
Installation
In Section 3.1 - The Method install of the Java Card� 2.1.1 Runtime Environment (JCRE) Specifications,
the parameters passed to the method are defined to be initialization parameters from the contents of the incoming
byte array parameter.
In the definition of the install method of the Class Applet of the Java Card� 2.1.1 Application Programming
Interface, the install parameters to be supplied must be in the format defined by the applet.
This specification expands on this requirement and further defines the content of the install parameters. This
expansion affects both the implementation of an OPEN and the behavior of a Java Card applet developed for a
GlobalPlatform card. It does not affect the definition of the install method of the Class Applet of the Java
Card� 2.1.1 Application Programming Interface specification.
The install parameters shall identify the following data, present in the INSTALL [for install] command (see
Section 9.5.2.3.2 - Data Field for INSTALL [for install]):
� The instance AID,
� The Application Privileges and,
� The Application Specific Parameters.
[While the APDU command contains install parameters representing TLV coded system and application specific parameters, the
application only requires knowledge of the Application Specific Parameters i.e. only LV of the TLV coded structure �C9� are
present as parameters.]
The OPEN is responsible for ensuring that the parameters (bArray, bOffset and bLength) contain the
following information:
The array, bArray, shall contain the following consecutive LV coded data:
_� Length of the instance AID,_
_� The instance AID,_
_� Length of the Application Privileges,_
_� The Application Privileges,_
_� Length of the Application Specific Parameters and,_
_� The Application Specific Parameters._
The byte, bOffset, shall contain an offset within the array pointing to the length of the instance AID.
The byte, bLength, shall contain a length indicating the total length of the above-defined data in the array.
The applet is required to utilize the instance AID as a parameter when invoking the register (byte []
bArray, short bOffset, byte bLength) method of the Class Applet of the Java Card� 2.1.1
Application Programming Interface specification.

Problem with string constructor when using byte array as parameter

I am creating a string using constructor and passing byte array as parameter.This byte array i am getting from MessageDigest's digest() method,i.e. a hash value.
The problem is when i iterate through byte array i can able to print all the values in byte array.But when i construct a string from that byte array and printing that string ,that is printing some unknown characters.
I don't know whether i need to pass charsequence to the constructor and the type of charsequence.Can anybody help me?
Thanks in advance

Is there some problem today? I'm getting this sort of thing all over.
I already told you and so did Kayaman. Don't. String is not a holder for binary data. You have to Base-64 encode it. If you don't you cannot reconstruct the original binary digest value, so putting it into a database is completely utterly and entirely pointless.
Is that clear enough?

Display an object of Image type or Byte Array

Hi, lets say i got an image stored in the Image format or byte[]. How can i make it display the image on the screen by taking the values in byte array or Image field?

Thanks rahul,
The thing is, i am generating a chart in a servlet
and setting the image in the form of a byte [] to the
view bean ( which is binded to the jsp, springs
framework ). The servlet would return the view bean
to the jsp and in the jsp, i am suppose to print this
byte array so as to give me the image..
I hope this makes sense.. pls help me ou!Well letme see if i got tht right or not,
you are trying to call Your MODEL (Business layer / Spring Container) from a servlet and you are expressing that logic in form of chart (Image) and trying to save it as a byte array in a view bean and you want to print /display that as an image in a jsp (After Servlet fwd / redirect action) which includes other data using a ViewBean.
If this is the case...
As the forwaded JSP can include both image and Textual (hypertext too)..we can try a work around hear...Lets dedicate a Servlet which retreives byte [] from a view bean and gives us an image output. hear is an example and this could be a way.
Prior to that i'm trying to make few assumptions here....
1).The chart image which we are trying to express would of format JPEG.
2).we are trying to take help of<img> tag to display the image from the image generating servlet.
here is my approach....

    }Note: Through ImageServlet is a Servlet i would categorise it under presentation layer rather to be a part of Controller and added to it all this could be easily relaced by a reporting(BI) server like JasperServer,Pentaho,Actuate................
Hope the stated implementation had given some idea to you....
However,If you want to further look into similar implementations take a look at
http://www.swiftchart.com/exampleapp.htm#e5
which i believe to be a wonderful tutor for such implementations...
However, there are many simple (Open) solutions to the stated problem.. if you are Using MyFaces along with spring... i would recommend usage of JSF Chart Tag which is very simple to use all it requires need is to write a chart Object generating methos inside our backing bean.
For further reference have a look at the below links
http://www.jroller.com/page/cagataycivici?entry=acegi_jsf_components_hit_the
http://jsf-comp.sourceforge.net/components/chartcreator/index.html
NOTE:I've tried it personally using MyFaces it was working gr8 but i had a hardtime on deploying my appln on a Portal Server(Liferay).If you find a workaround i'd be glad to know about it.
& there are many BI Open Source Server Appls that can take care of this work too.(Maintainace wud be a tough ask when we go for this)
For, the design perspective had i've been ur PM i wud have choose BI Server if it was corporate web appln on which we work on.
Hope this might be of some help :)

Strange issue with POF: byte array with the value 94

This is a somewhat strange issue we’ve managed to reduce to this test case. We’ve also seen similar issues with chars and shorts as well. It’s only a problem if the byte value inside the byte array is equal to 94! A value of 93, 95, etc, seems to be ok.
Given the below class, the byte values both in the array and the single byte value are wrong when deserializing. The value inside the byte array isn’t what we put in (get [75] instead of [94]) and the single byte value is null (not 114).
Pof object code:
package com.test;
import java.io.IOException;
import java.util.Arrays;
import com.tangosol.io.pof.PofReader;
import com.tangosol.io.pof.PofWriter;
import com.tangosol.io.pof.PortableObject;
public class PofObject1 implements PortableObject {
     private byte[] byteArray;
     private byte byteValue;
     public void setValues() {
          byteArray = new byte[] {94};
          byteValue = 114;
     @Override
     public void readExternal(PofReader reader) throws IOException {
          Object byteArray = reader.readObjectArray(0, null);
          Object byteValue = reader.readObject(1);
          System.out.println(Arrays.toString((Object[])byteArray));
          System.out.println(byteValue);
          if (byteValue == null) throw new IOException("byteValue is null!");
     @Override
     public void writeExternal(PofWriter writer) throws IOException {
          writer.writeObject(0, byteArray);
          writer.writeObject(1, byteValue);
Using writer.writeObjectArray(0, byteArray); instead of writer.writeObject(0, byteArray); doesn't help. In this case byteArray would be of type Object[] (as accessed through reflection).
This is simply put in to a distributed cache and then fetched back. No EPs, listeners or stuff like that involved:
     public static void main(String... args) throws Exception {
          NamedCache cache = CacheFactory.getCache("my-cache");
          PofObject1 o = new PofObject1();
          o.setValues();
          cache.put("key1", o);
          cache.get("key1");
Only tried it with Coherecne 3.7.1.3.
Cache config file:

Hi,
POF uses certain byte values as an optimization to represent well known values of certain Object types - e.g. boolean True and False, some very small numbers, null etc... When you do read/write Object instead of using the correct method I suspect POF gets confused over the type and value that the field should be.
There are a number of cases where POF does not know what the type is - Numbers would be one of these, for example if I stored a long of value 10 on deserialization POF would not know if that was an int, long double etc... so you have to use the correct method to get it back. Collections are another - If you serialize a Set all POF knows is that you have serialized some sort of Collection so unless you are specific when deserializing you will get back a List.

Display byte array image or ole object in Section through dynamic code?

To Start I am a Complete Newbe to Crystal Reports. I have taken over a project originally written in VS2003 asp.net using SQL Server 2005 and older version of Crytal Reports. I have moved project to VS2010 and Cryatal Reports 10 still using SQL Server 2005. Have multiple reports (14 to be exact) that display data currently being pulled from database suing a dataset, each report has from 4 to 14 Sections. I have modified database table with two new fields. Field1 contains string data with full path to a scanned document (pdf or jpeg). Field2 holds a byte array of the actual image of the scanned document. I have tested the database and it does infact contain the byte array and can display the image via VB.net code. I can make the report display the scanned image using ole object.
Now my real question: I need to add a new Section and it should display either the byte array of the scanned image or the actual scanned image (pdf or jpeg) . How can I have it do either of these options via code dynamicly while application is running?

First; only CRVS2010 is supported on VS2010. You can download CRVS2010 from here;
SAP Crystal Reports, developer version for Microsoft Visual Studio: Updates & Runtime Downloads
Developer Help files are here:
Report Application Server .NET API Guide http://help.sap.com/businessobject/product_guides/sapCRVS2010/en/xi4_rassdk_net_api_en.zip

SAP Crystal Reports .NET SDK Developer Guide http://help.sap.com/businessobject/product_guides/sapCRVS2010/en/crnet_dg_2010_en.zip
To add the images, you have a number of options re. how to. You even have two SDKs that y ou can use (RAS and CR).
Perhaps the best place to start is with KB [1296803 - How to add an image to a report using the Crystal Reports .NET InProc RAS SDK|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_bi/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333233393336333833303333%7D.do]. The KB describes how to add images to a report using the InProc RAS SDK, but also references other KBs that use CR SDK.

Hi VS,
I think I haven't explained it clearly.
I have used the file upload component to get the data from a file.. and of course with a context attribute of binary type. I have to assign this byte[] to the web service model method parameter. But to my fascination, the webdynpro application crashes on start throwing the above mentioned exception.
Any Idea??
thanks

Byte[] Arrays in CMP Entity bean

Hello
One of my fields for a CMP Entity beans is a byte[] Array. When i do a
home.create(primarykey, byteData)
i get an exception saying - "Trying to insert a null in a non-nullable column"
My data is not a null at that point. If i change the byte[] array to a string, it works fine. Does anybody have any suggestions. I am using JBOSS appserver.
thanks
Dash

thanks for you reply. i was using cmp with ejb2.0, wherein i do not have to do anything under postcreate(), implementation is handled by the container i guess. But, coming to my problem: I figured out why i got that error. i had a table by the same name with a differnt data type. JBOSS did not report to me saying that the TABLE already exists.
thanks
