Search ZIP File with Regex - Java NIO Example

2013-02-26T19:24:00.000-08:00

In this example, we will discuss how to use regular expressions to search and find entries inside a ZIP file using a Java program. This post can be considered as an extension to the earlier post on Glob pattern based search on ZIP Files using Java.We will be using the same approach as outlined in the Glob tutorial to do a regex based search. The differences alone will be discussed in this

Search ZIP File -Glob Pattern -Java NIO Example

2013-02-24T18:19:00.000-08:00

In this example, we will describe how to search a ZIP Archive with a Glob / Wild Card pattern, using a Java NIO program. We will read the ZIP File using Zip File System Provider, and use java.nio.file.PathMatcher to match the pattern we want to search with the contents of the ZIP file. This article is built on top of the search ZIP Entries by File Name tutorial. You may wish to refer to the

Search ZIP File using Java - NIO ZPFS Example

2013-02-20T19:43:00.000-08:00

In this tutorial, we will explore the idea of searching a ZIP Archive for a specific file using Java, with an example program. Instead of the traditional java.util.zip ZipEntry approach, we will use NIO and ZPFS (Zip File System) to mount a zip file as a file system. After this we will use the walkFileTree method available in NIO to scan the ZIP file tree and locate the file we want. Sounds

Rename ZIP entries with NIO / ZPFS - Java Example

2013-02-19T16:42:00.001-08:00

In this example, we will discuss how to rename entries inside a ZIP file in Java using Zip File System Provider (ZPFS) implementation. ZPFS concept is linked to Java NIO and you will wonder how easily this task can be accomplished with very less coding. Without ZPFS, you will have to extract the entire archive, work harder to rename individual files and then create another ZIP file completely.

Search Word Document Using Java Example

2013-02-13T20:19:00.000-08:00

In this tutorial, we will examine the possibility to search a Microsoft Word document for a text / pattern, using a Java program. We will use Apache POI to parse the Word document and java.util.Scanner to perform a string search, and report the number of occurrences of the input pattern as the output. This tutorial is targeted for beginners, and you can feel free to extend the code provided

Add Files to Existing ZIP Archive in Java – Example Program

2013-02-11T17:28:00.000-08:00

In this tutorial, we will see how to add a file to an existing ZIP file, using Java, with an example. We will use Java NIO’s new feature ZIP File System Provider to append files to existing files. ZIP File System Provider is capable of treating a ZIP File as a File System. This would mean adding files to an existing archive would be as straight forward as copying a file from your disk to the

Delete Files from ZIP Archive – Java Example

2013-02-10T20:24:00.000-08:00

In this tutorial, we will discuss how to delete files from a ZIP Archive using ZPFS (Zip File System Provider) and Java NIO, with a suitable example. We will provide a step by step guide for deleting entries in a ZIP file. These steps are captured below: Steps to Delete ZIP File Entries through Java Program - ZPFS - NIO Example 1.Define ZIP File System Properties We have discussed

Extract ZIP Files using ZPFS - Java NIO Example

2013-02-06T18:38:00.001-08:00

In the previous post, we discussed how to use ZPFS in Java NIO, to create a new ZIP archive and add some files into it. In this post, we will discuss about extracting files from ZIP Archive using the same technique. At the end of the tutorial, you will realize how easy it is to extract entries from ZIP file using ZPFS. The list of steps involved in extracting files is captured below: Steps

Java NIO ZIP File System Provider Example

2013-02-05T16:12:00.000-08:00

ZIP File System Provider – Java NIO - Introduction In this tutorial, we will discuss how to use ZIP File System Provider (ZFSP) which is capable of treating a ZIP file as a file system in Java and manipulate ZIP files using it with some Java examples. ZFSP can treat a ZIP file like a file system (i.e. a ZIP file can be managed as your C drive for example), and makes addition / deletion /

Extract TAR File PeopleCode Example

2013-02-03T16:53:00.000-08:00

In this tutorial, we will explain how to extract a TAR file in PeopleCode using JTAR Java library. If you are looking to generate a TAR file in PeopleSoft, then you should refer to create TAR file tutorial. You can always run native UNIX commands to extract TAR file before processing them in PeopleCode, however a Java based solution is much cleaner and is independent of the operating system

Oracle LISTAGG Function Example

2013-01-23T01:19:00.001-08:00

Today I read about LISTAGG aggregate / analytic function in Oracle, and thought would write a short blog about this, explaining various methods of using LISTAGG with suitable examples. I’m going to approach this tutorial with really simple examples so that you can understand LISTAGG completely. The tutorial assumes you know some basics of SQL, using aggregate functions and analytic functions.

Create MD5 Hash for File in PeopleCode - Example

2013-01-21T17:10:00.000-08:00

In this tutorial, we will explain how to create a MD5 hash / Checksum for a file in PeopleSoft, with a PeopleCode example. We will utilise java.security.MessageDigest to generate the MD5 hash. You can easily stick this code to an Application Engine program or even a record field event, depending on your requirements. The high level steps involved in creating a MD5 hash are captured below:

Read / Extract ZIP Files - PeopleCode Example

2013-01-20T16:38:00.000-08:00

In this tutorial, we will discuss how to Read / extract a ZIP file in PeopleSoft with a PeopleCode example. If you are looking to ZIP a file in PeopleCode, you should refer to our earlier tutorials. We will be using java.util.zip.ZipInputStream to read a ZIP file in PeopleSoft, and then extract every entry inside the ZIP file to a file on disk using the methods available in Java, extended to

Create ZIP / TAR / .GZ Files in PeopleCode Example

2013-01-16T19:52:00.000-08:00

We have been discussing about manipulating TAR and TAR.GZ files in PeopleSoft at length so far. This discussion would never be complete without providing a tutorial to compress files in ZIP format from PeopleCode. I thought I will write a single code section that will be able to compress a file / set of files in various formats viz tar, tar.gz and zip. It is to be noted that the approach to

Create .tar.gz File in PeopleCode Example

2013-01-15T20:52:00.000-08:00

In this tutorial we will describe how to create a .tar.gz file in PeopleCode, using native Java libraries and JTar. We will be using examples from our tutorials earlier for this, and so make sure you read (strongly recommended) the following tutorials before starting with this one: Create GZIP File in PeopleCode - Explains how to create .gz file in PeopleCode Create TAR File in PeopleCode -

Create TAR File in PeopleCode - Example

2013-01-15T17:53:00.000-08:00

In this tutorial, we will explain how to create a TAR file in a PeopleSoft application by using PeopleCode and Java. There is no native support available in Java to create a TAR file, and to overcome this limitation, we will use JTAR library inside PeopleSoft and generate our TAR file. You should download a copy of JTAR (look into references below )for trying out the example provided in this

Create GZIP File in PeopleCode - Example

2013-01-14T20:30:00.000-08:00

In this tutorial, we will discuss how to create a GZIP file through PeopleCode with an example code. You can compress only single files through GZIP normally and we will utilize the features provided by java.util.zip.GZIPOutputStream class, to achieve the .gz compression. I assume that you have a basic understanding of CreateJavaObject usage in PeopleCode. The different steps we have to write
