Java library management with Maven

Using Maven, the library management is as intuitive as it could ever be.  "DLL hell" headache is over by specifying the version of the library in the project pom.xml file.  Furthermore, all JAR files are managed and stored locally as any requests are made by the project.

Maven configuration is specified in a file called POM, specified in pom.xml.  This XML formatted file specify all that the compiler would need, including the package configuration and libraries.

If you are not using Maven and copying the Complex library JAR file into your project library, the library management is manual.  Which means, you would have the same copy of the JAR files all over the place for whichever project that needs it.  If the library is updated, you would download the updated file for all the projects that use the library.

Supposing you have Complex library and your projects Mandelbrot and Misiurewicz  need that library. Using Maven, incorporating that library is as simple as it could be.  Edit pom.xml and specify dependency in your pom.xml file.  As you compile the project, the Complex library JAR files will be stored and managed locally.

Now you want compile Misiurewicz project that uses Complex library.  Edit your pom.xml file for the project, and the Complex library is available locally without copying the files into the project.

All can be managed by Maven.

Edit pom.xml for generating an excutable JAR.  Specify the main class. Specify jar-with-dependencies and all the necessary JAR files will be included in the generated executable JAR file.

Logging your Maven project with Logback

How do you trace your app?  Well, simple standard output is enough for simple applications.   What if, however, you'd want layered commeting/tracing?  Supposing, say, you do not want lengthy trace info for regular use of your app?  The error reports certainly should be distinguished from debugging info. Logback is a nice package that does the work.  Your app will emit any sort of messages, with proper labels (error, warning, info, debug, trace).  Load the library by editing pom.xml file.   < dependency > < groupId > ch.qos.logback </ groupId > < artifactId > logback-classic </ artifactId > < version > 1.2.2 </ version > </ dependency > The log file should be specified in logback.xml file.  The file should be under src/main/resources.   <? xml version = "1.0" encoding = "UTF-8" ?> <! DOCTYPE logback > < configuration > &

TreeEditor: Customizing Drag and Drop

JTree is a Java GUI component for tree structure.  The tree structure is represented by nodes ( DefaultMutableTreeNode ).  The path or the placement of the node in the tree is represented by TreePath . DefaultMutableTreeNode selectedNode = (DefaultMutableTreeNode) tree.getLastSelectedPathComponent(); Use TransferHandler for drag and drop.  Supposing a class derived from TransferHandler called MenuTransferHandler handles drag and drop, set the TransferHandler as follows: MenuTransferHandler handler = new MenuTransferHandler(); treeEditor . tree .setTransferHandler(handler); The copied new node should be generated at TransferHandler#createTransferable() .  Here shows the function copy() that may come in handy in writing createTransferable() .   copy() should be called recursively. private DefaultMutableTreeNode copy (TreeNode node) { DefaultMutableTreeNode newNode = new DefaultMutableTreeNode(node); if (!node.isLeaf()) { @Supp

Spring Tool Suite

The Spring Framework offers a safe webapp framework with integrated Hibernate style database mapping. With Spring Tool Suite, all the config parameter settings are taken care of. Using STS, you can start out writing the Spring app rıght away. A word of caution, it may demand JVM (32bit version). → Spring Tool Suite The default port number 8080. That can be set by specifying it in src/main/resources/application.properties file. server . port = 8090 Using STS, the database mapping called JPA is as simple as specifying in pom.xml. The mapped class should be specified by annotation. As for HTML pages, Thyme leaf is recommended and instead of JSP. < dependencies > < dependency > < groupId > org.springframework.boot </ groupId > < artifactId > spring-boot-starter-data-jpa </ artifactId > </ dependency > < dependency > < groupId > org.springframework.b
