How To Import Library Into Jdeveloper



You can create new files of various types from scratch or open existing ones. When opening existing files, you can import them, along with their file structure, into an existing project or build a completely new project around them.




how to import library into jdeveloper



You should not use this procedure to import an EAR file that you simply wish to deploy using JDeveloper. To do this, create a new application and project, then copy your EAR file into the project directory (or add its location to the project's content). The EAR file will then appear in the Applications window under the project's Application Sources node. From here, you can deploy the file by right-clicking it and choosing Deploy to.


External library definitions are persisted within their own stand-alone library definition file (that is, the .library file). As such, external libraries can be checked into source control, referenced by any number of projects, and can be shared among all users in a team environment in the same way that java source files are. Since external libraries have their own unique URL, adding an external library to a project adds that URL to the project.


The first thing you need in order to build your ADF View project with Maven is to load all of the required libraries into your Maven repository. Luckily, there is already a tool written that will extract all of the library definitions from JDeveloper, generate the corresponding POM files for them, and generate shell scripts to simplify the importing of the JAR files and library definitions. The tool is called maven-adf and can be downloaded from the google code site at -adf/.


In this first part, you can see how to import the JDeveloper libraries that are required to build an ADF project into a Maven repository. In the next part we will look at what it takes to build the WAR file for an ADF project, followed by an EAR project to package one or more WAR files for deployment, and lastly a demonstration of a full working solution built from a Jenkins server and deploying the resulting artifacts to a Nexus repository.


Hi Andrejus,if i understand the second approach is the best to use in jdev 11gR2So I tried to upgrade a project migrated from 11.1.1.5 and dataControls detail are visible butwhen i rebuild the viewControl project i see that i lost all java classes references let me explain.. in to my class bean i see all class packages imported without apparent errors,but when i compile the view control the compiler-log tell me many Error type "package does not exist"you think that I need to include the adf library jars in the classpath of my view control project, even if they are presents in the project model?(i inform you that project model.jpr is present in my view Control project property dependencies)thank you for your timeGio


After that if dependency jar file is not already in your Maven local repository you need to execute Maven install goal in order for maven to download the jar and JDeveloper can see it in the local filesystem. After that you can add an import and write code to java files using the classes from downloaded library/framework jar.


I am now experiencing the same issue though for JDeveloper. The simplier question is how to import external jar files into your project. There is an additionalstep that just importing the jar files into the library. For JDeveloper, you are required to assign the Library (which contains the jar files) to the project.


A couple of things to bear in mind when creating this connection; first, if you intend to deploy the ADF application to a proper application server (rather than the embedded WebLogic Server within JDeveloper), you'll need to package up the Presentation Server credentials using migrateSecurityStore.py and then import them into that application server's credential store, so that the application can then refer to them when trying to connect to OBIEE (see this presentation from last year's Openworld for the process for JDeveloper/OBIEE 11.1.1.5). Second, you may well have SSL set up on your OBIEE server, and if that's the case you'd need to generate an SSL certificate from the OBIEE side, then import that into the environment that'll be running your application, with details of what's involved here in the OBIEE 11.1.1.6 Developers Guide manual. But now, we'll go for a simple unencrypted connection using the BIImpersonateUser to initially connect, and then the application's logged-in user credentials used to browse the Presentation Services catalog.


Users will get an oracle.toplink.workbench.external.meta.ExternalClassNotFoundException error if they try to import new classes (.java) into a project with the TopLink technology selected, and subsequently attempt to map these classes by selecting the "add descriptor" button under the TopLink node in the Structure pane. In order to eliminate this error, users should compile the classes once before mapping them the first time.

When running the application via JDeveloper (in our example application by right clicking default.jsf in the ViewController project, and selecting Run), we see that the task flow that comes directly from the ViewController project (the table on the left of the screen), behaves as expected. However, when personalizing the table from the task flow that comes from the imported library (so from the ViewControllerLibrary project), we see the following warning in the log files.


This application consists of the default Model and ViewController projects. Also, we added a ViewControllerLibrary project. This ViewControllerLibraryproject is imported as a library by the ViewController project.


However, this method was not a published public method, so I decided that it would be better to take a copy and put it into my own library. As it happens, over the last few years I have been building up a small library of OA Framework classes designed to make OAF development easier and more efficient. This libarry is called the OA Framework Toolkit; it is open source and can be downloaded from SourceForge. The OAF Toolkit has classes for all different aspects of OAF development; this particular method I added to the WebBeanUtil class in the com.oaframework.toolkit.util package: 2ff7e9595c
