ERROR!!

You have to define your gvSIG platform properties, 

by creating the file: ${user.home}/.gvsig.platform.properties

with the following content:

native_platform=linux

native_distribution=all

native_compiler=gcc4

native_arch=i386

native_libraryType=dynamic

export native_classifier=${native_platform}-${native_distribution}-${native_compiler}-${native_arch}-${native_libraryType}

Replace the fifth initial variables values with the ones appropiate 

to your platform.

If you use maven in the command line, you can use the previous file also

to define the MAVEN_OPTS environment variable, by adding to your 

.bash_rc file something like this:

if [ -f "${HOME}/.gvsig.platform.properties" ]

then

    . ${HOME}/.gvsig.platform.properties

    export MAVEN_OPTS="-Xmx256M -XX:MaxPermSize=64m -Dnative-classifier=${native_classifier}"

else

    export MAVEN_OPTS="-Xmx256M -XX:MaxPermSize=64m"

fi

It will work if you use the bash shell. In any other case or platform, you'll

have to define your MAVEN_OPTS environment variable and set the 

"native-classifier" parameter directly.

The first time you checkout the current project to a new workspace, 

you have to prepare it to be able to work easily with maven from

eclipse itself.

Perform the following steps:

1.- Launch the *prepare-workspace.xml* ant build file. 

    You can do it by loading the file into the ant view, 

    and running the default task, or right-clicking the 

    file from the package explorer or the navigator and

    select the option: *Run as > Ant build*. 

2.- Restart eclipse.

3.- Import the subprojects of the project you have just checked out.

Those steps are only needed once per workspace.     

Put into this folder the resources needed by your classes.

This folder is added to the classpath, so you can load any resources 

through the ClassLoader.

By default, in this folder you can find an example of log4j configuration,

prepared to log messages through the console, so logging works when you

run your classes.

<?xml version="1.0" encoding="ISO-8859-1" ?>

<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<!-- 

Log4J configuration file for unit tests execution.

 -->

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

	<!-- Appender configuration to show logging messages through the console -->

	<!--
