8.3.1. Initial Setup of Web Project¶
The following is procedures of initial setup of the web project:
- Generate web project
- Confirm communications of the web project
8.3.1.1. Overview of the generated project¶
The overview of the project generated by this procedure is as follows.
| Item | Description |
|---|---|
| Project type | Maven project |
| Project composition | Single project composition |
| DB used | H2 Database Engine (embedded in the application) |
| Built-in adapter | Routing adapter (for details, see Routing Adapter) |
| What is included in the generated project? | The following is included in the generated project:
|
For relationship with other projects and directories, see Maven Archetype Configuration.
8.3.1.2. Create blank project¶
Generate a blank project using the archetypes provided by Nablarch.
8.3.1.2.1. Execute the mvn command¶
Use Maven Archetype Plugin(external site) to generate a blank project.
Change the current directory to the directory where the blank project (can be any directory) is to be created, and place the following file.
After placing the file, specify the necessary parameters in the arguments and execute the bat file.
generateWebProject.bat 5u22 <<groupId>> <<artifactId>> <<version>> <<package(optional)>>
The parameters configured in the above command are as follows. To change the version of nablarch, change 5u22.
| Input item | Description | Configuration example |
|---|---|---|
| groupId | Group ID (normally, enter the package name) | com.example |
| artifactId | Artifact ID | myapp-web |
| version | Version number | 0.1.0 |
| package | Package (normally the same as group ID) | com.example |
Important
Item groupId and package are mapped to the Java package name. Use lowercase letters, numbers, and dots for these input values, and do not use hyphens.
If the command ends normally, a blank project is created under the current directory.
8.3.1.3. Communication confirmation¶
8.3.1.3.1. Automated test¶
The following unit tests are included in the project generated from the archetype.
| Unit test classes | Test content |
|---|---|
| SampleActionRequestTest | Use Nablarch testing framework to check if the screen is visible. |
Execute the unit test and confirm that the blank project was successfully generated.
Execute the following command.
cd myapp-web
mvn test
Tip
“clean” and “test” of Maven used here are Built-in Lifecycle of Maven.
For information on other lifecycles that exist, see Built-in Lifecycle Bindings (external site).
If the execution is successful, the log given below will be output to the console.
(omitted)
[INFO] -----------------------< com.example:myapp-web >------------------------
[INFO] Building myapp-web 0.1.0
[INFO] --------------------------------[ war ]---------------------------------

8.3.1.3.2. Launch confirmation¶
The following screen is included in the generated project.
| Class used for screen display | Details |
|---|---|
| SampleAction | Confirm communications of Nablarch functions commonly used when implementing web applications. |
Confirm that the blank project has been successfully generated by displaying the screen on the browser.
If the current directory is not yet moved to the generated project, move the directory.
cd myapp-web
Execute the following command to build the web application.
mvn compile
Execute the following command to start the application for communication confirmation on the web module.
mvn waitt:run
Tip
“waitt:run” of Maven used in the above command example is a specification to use the run goal of the waitt maven plugin.
For information on the waitt maven plugin, see waitt maven plugin (external site).
The browser will automatically start up if the launch is successful and the communication confirmation screen will be displayed. Read the contents of the displayed page and confirm that the launch was successful.
Check the log to make sure that an error has not occurred.
8.3.1.3.3. If the communication confirmation fails for some reason¶
If the communication confirmation fails for some unknown reason, the correct procedure may not have been followed in some part.
If the reason is not known, try again from Create blank project.
8.3.1.4. Supplementary information (web.xml)¶
Although <resource-ref> element has to be defined in web.xml to obtain a connection through JNDI, web.xml is shared instead of being separated for each environment for ease of management.
When acquiring the connection through JNDI only in the production environment, <resource-ref> element definition is not required as a setting for the development environment of the local PC, and unless the code that uses the definition is written in the application, <resource-ref> elements are not used. Therefore, a problem does not occur during the operation of the application in the development environment of the local PC.
Tip
Custom server.xml cannot be loaded in Tomcat, which is launched by waitt maven plugin. When running the application using the waitt maven plugin, JNDI cannot be used even if the element <resource-ref> is defined in web.xml.
8.3.1.5. Supplementary notes¶
For information on the method of confirming the data of H2 and tools included in the blank project, see Initial Setup Procedure Supplementary Information.
