Set file permission in Java
Prior to Java 6, there is no good solution at the Java level to provide file permission management. You need to implement your own native methods or call the Runtime.exec() to invoke the system routine such as chmod in LInux. Since Java 6, Java introduces a set of methods which can be used to set the file permission at Java level. These methods include: File.setReadable(boolean); File.setWritable(boolean); FIle.setExecutable(boolean); File.setReadable(boolean, boolean); File.setWritable(bo...

Generating CSR using Java
A CSR(Certificate Signing Request) is a kind of request generated by an application and is to be sent to a Certificate Authority to create a signed certificate which can be distributed. It usually contains certificate information such as subject name, public key info and signature info. In Java, keytool can be used to generate a certificate request with option -certreq. But sometimes if an application wants to create a CSR programmatically, keytool will not do a favor, instead you should u...

Different types of keystore in Java -- BKS
BKS is a keystore format provided by the popular third party Java cryptographic library provider -- BouncyCastle. It is a keystore similar to the JKS provided by Oracle JDK. Before starting to use BKS, the BouncyCastle provider has to be downloaded and installed. To download the provider, please go to BouncyCastle download page. The provider can be installed by adding an entry in the java.security file. security.provider.N=org.bouncycastle.jce.provider.BouncyCastleProvider N means the pr...

A HTTPS client and HTTPS server demo in Java
In this post, I will create a HTTPS server and HTTPS client demo which can establish HTTPS communication between a server and a client using Java. This should be very useful when we want to test our understanding about SSL communication. We will use both a detailed SSL client and a simple HttpsURLConnection as the HTTPS client. Before creating the actual HTTPS server and HTTPS client, we first need to generate the keystore and truststore to be used by the server and client. To generate the keyst...
Java code to retrieve Bing background image path
When Microsoft presented their search engine Bing, this new design gave us some surprise, especially its background images, they are very beautiful and it will change every day. But unfortunately we cannot save the image onto our PC by right clicking the mouse. After some research on its source code, I found a feasible but not so sophisticated way to achieve this, we can retrieve the image path from the source code and then use this path we can download the image. This is just to sh...

The difference between System.load and System.loadLibrary in Java
When writing code using native library in Java, normally the first step is loading some native library. static{   System.load("D:" + File.separator + "Hello.dll"); } JDK provides two ways to load libraries: System.load(String filename) System.loadLibrary(String libname) This post will try to explain the differences of these two ways. According to Java Doc on System.load(), it has below description. Loads the native library specified by the filename argument. The filename a...

The latest on Java-on-Java: the Oracle experiment that is gaining momentum
What is Project Metropolis? The not so hush-hush Project Metropolis is all set to implement Java on itself – popularly known in the developer community as Java-on-Java. Oracle has released updates on its progress, and they are very encouraging. The project will focus on building a JIT (just in time) compiler that is written in Java. It is being touted as the experimental clone of JDK (Java Development Kit) 10. Work on ‘ahead of time’ compiling and Graal compiler is also i...
