bytearray

问题 I want to send a message to a JMS Queue, and I want to set an object property: tMessage.setObjectProperty("JMS_IBM_MQMD_MsgId", bytes); //bytes is a byte array value But I am getting an exception for this row: tMessage.setObjectProperty("JMS_IBM_MQMD_MsgId", toByteArray((phone+"IBM").toCharArray())); Why cannot I set byte array to this property? I saw some example, and everyone sets bytearray, but I am getting exception: weblogic.jms.common.MessageFormatException: [JMSClientExceptions:055123

问题 I've a byte[] of certificate data and I want to change this byte[] type to Certificate type. How can I achieve this? Now I used CertificateFactory.generateCertificate(InputStream inStream) . byte[] csr = getCSR(cn, ou, org, loc, state, country,email); CertificateFactory cf = CertificateFactory.getInstance("X.509"); ByteArrayInputStream bais = new ByteArrayInputStream(csr); Certificate certificate = cf.generateCertificate(bais); But Error occurred Certificate certificate = cf

问题 I have the following code: var v = [0xFF, 0xFF]; alert((v[0]<<8) | v[1]); And it alerts 65535 (the max short value). How can I treat this byte array as a signed short, and get the signed value of this array. 回答1: Assuming the higher bit is the sign: var sign = v[0] & (1 << 7); var i = ((v[0] & 0x7F) << 8) | v[1]; if (sign) { i = -i; } http://jsfiddle.net/p4TQw/1/ If you use the Two's complement representation: var i = (((v[0] << 8) | v[1]) << 16) >> 16); The 16 bits left shift moves all bits

问题 I want to write byte array to txt file. Firstly I want to see that data in eclipse console and I see that data are true. But when I want to write this data into txt file the problem is manifest itself. Txt file is coming with errors. My code is as follows. FileOutputStream fos; try { fos = new FileOutputStream("/usr/text110.txt"); fos.write(imageInByte); fos.close(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO

问题 How can write content in a byte array to a file and read the byte from file back to byte array without changing the content written before. in java 回答1: There are two methods for exactly this, in Files final Path path myFile = Paths.get("path","to","file"); final byte[] toWrite = ... Files.write(myFile, toWrite, StandardOpenOption.CREATE_NEW); final byte[] read = Files.readAllBytes(myFile); assert Arrays.equals(toWrite, read); 来源： https://stackoverflow.com/questions/29508294/write-content-in

问题 I am trying to get the UserdefinedProperties of an Open Office Writer Document. My questions are first how can i adress the currently open file in the writer? And how can i access the metadata after I told the programmm from which file it should get the data? hopefully someone of you can help me. Thank you very much. 回答1: Check this interface XDocumentProperties Reference< XDocumentInfoSupplier > xDocumentInfoSupplier(xComponent, UNO_QUERY); Reference< XDocumentInfo > xDocumentInfo =

问题 I have an array char input[11] = {'0','2','7', '-','1','1','2', ,'0','0','9','5'}; How do I convert input[0,1,2] to int one = 27 , input[3,4,5,6] to int two = -112 and input[7,8,9,10] to int three = 95 ? thx, JNK 回答1: You can use a combination of strncpy() to extract the character range and atoi() to convert it to an integer (or read this question for more ways to convert a string to an int). int extract(char *input, int from, int length) { char temp[length+1] = { 0 }; strncpy(temp, input

问题 This question already has answers here : How to store a byte array in Javascript (3 answers) Closed 3 years ago . The ByteArray class provides methods and properties to optimize reading, writing, and working with binary data. How to use byte arrays tutorial. I'm looking for a very similar API as the one linked. I'm looking for a class the browser provides not hack or workaround. The linked question does not provide the answer. If it does please provide a link to the documentation. Some one

问题 With reference to my previous question. I have made the program with the following approach: The program first reads 2k of data from the file and stores it into a byte array. Then the data to be added to each packet is also stored in an array and both are added to an array list. The array list is then written to an output stream for the file. The Code is here: File bin=chooser.getSelectedFile(); int filesize=(int)bin.length(); int pcount=filesize/2048; byte[] file=new byte[filesize]; byte[]

问题 I am sending a Byte array which was originally a binary in the database. the processes of sending the byte array is fine, but the problem is how can I handle this byte array. 1) can I handle it using javascript, I mean can I retrieve the byte array and convert it back to its original state. if yes how ? 2) if no what other way I can do that. What I want to do is to make the client side able to download files from the WCF without using a stream, I don't need stream because I know that the
