Before developing an application with dm Server, it is essential to install dm Server, the Eclipse Integrated Development Environment (IDE), the Eclipse-based dm Server Tools, and a build system integrated with Eclipse. The present document uses Apache Maven and the Eclipse plugin Q for Eclipse to integrate the IDE with the build system.
Before proceeding, ensure that a Java™ Standard Edition Development Kit
for Java 5 or later is installed and that the JAVA_HOME environment variable is set to the correct value.
To verify this, issue the command "%JAVA_HOME%"\bin\java -version from
a command prompt on Windows or $JAVA_HOME/bin/java -version from a terminal window on UNIX and ensure that
the command completes successfully and reports
a Java version 1.5 (denoting Java 5) or greater.
Also issue the
command "%JAVA_HOME%"\bin\jar to ensure that there is a means of extracting files from zip archives.
If the jar command is
unavailable, download and install a suitable zip program such as 7zip,
gzip, or WinZip. This is most relevant for Windows
operating systems where the inbuilt zip extraction utility may mishandle long pathnames.
