Maven Eclipse Web Development

need to know spring mvc
need to know how to apply the connection pool
need to know how to use maven in the eclipse
setup in command prompt
add mssql jar to the self repo
need to know how to setup JNDI resources in the servers

Local Development Environment Setup

Prepare Eclipse for Maven
- Install springsource-tool-suite to Eclipse, or
- Download the all-in-one internal installation or get it from another colleague.
(Optional but recommended) Install Maven to your machine.

Maven's Central Repository

https://repo.maven.apache.org/maven2

Internal repository

Includes artifacts not available in the Central Maven Repository:

CrystalReports Java runtime libraries

https://archive.sap.com/documents/docs/DOC-29757

Oracle JDBC driver

http://www.oracle.com/technetwork/apps-tech/jdbc-112010-090769.html

MS SQL Server JDBC driver (Type 4)

https://docs.microsoft.com/en-us/sql/connect/jdbc/microsoft-jdbc-driver-for-sql-server?view=sql-server-2017

Download site for v4.2: https://www.microsoft.com/en-us/download/details.aspx?id=54671

JT400 - IBM Toolbox for Java, which includes the JDBC driver to access CAPSIL data

https://www-03.ibm.com/systems/power/software/i/toolbox/

Build from Command Line

mvn clean package

Skip Test

-Dmaven.test.skip=true

Maven Repo Download Problem

download the cert ⇒:gn16:jssecacerts.zip

then extract and put the file to the $JAVA_HOME/jre/lib/security/ (NOTE: must use JDK and not JRE)

it could resolve the connection and ssl problem between the central repo and local development machine which is behind websense (https://repo.maven.apache.org/maven2)

the cert is generated by the java program ⇒ :gn16:installcert.zip

https://github.com/escline/InstallCert/blob/master/InstallCert.java

/cygdrive/c/temp $ java InstallCert
Usage: java InstallCert <host>[:port] [passphrase]

https://web.liferay.com/web/neil.griffin/blog/-/blogs/fixing-suncertpathbuilderexception-caused-by-maven-downloading-from-self-signed-repository

download the ssl cert from https://repo.maven.apache.org/maven2/

add to the eclipse ssl cert (preference → search ssl)

https://stackoverflow.com/questions/19537396/missing-artifact-com-microsoft-sqlserversqljdbc4jar4-0

add sqljdbc42 to the self repo if the connection to mssql database is required

mvn install:install-file -Dfile=sqljdbc42.jar -DgroupId=com.microsoft.sqlserver -DartifactId=sqljdbc4 -Dversion=4.2 -Dpackaging=jar

Maven Related Issue, i.e. cannot compile, error and etc... need to clean maven or remove local .m2

Using Jetty

need to apply and use the maven jetty plugin

      <!-- jetty-maven-plugin -->
      <plugin>
        <groupId>org.eclipse.jetty</groupId>
        <artifactId>jetty-maven-plugin</artifactId>
        <version>${jetty-maven-plugin.version}</version>
        <configuration>
          <scanIntervalSeconds>5</scanIntervalSeconds>
          <httpConnector>
            <port>9090</port>
          </httpConnector>
          <webApp>
            <contextPath>/codenotfound</contextPath>
          </webApp>
        </configuration>
      </plugin>

download and using jetty-runner

      <!-- jetty-runner -->
      <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-dependency-plugin</artifactId>
          <version>2.3</version>
          <executions>
            <execution>
              <phase>package</phase>
              <goals><goal>copy</goal></goals>
              <configuration>
                <artifactItems>
                  <artifactItem>
                    <groupId>org.eclipse.jetty</groupId>
                    <artifactId>jetty-runner</artifactId>
                    <version>9.3.3.v20150827</version>
                    <destFileName>jetty-runner.jar</destFileName>
                  </artifactItem>
                </artifactItems>
              </configuration>
            </execution>
          </executions>
        </plugin>
