Finally understand how to succesfully add a Postgis Layer...

Hi, as you may have guessed from the post title I'm tring to add a Postgis Layer to Geomajas.

I tried to use Hibernate but, tell me if I'm wrong, I have to define also a java class with the structure of the postgis table, so at the moment I've decided to try to use geotools layer.

I checked that the geotools plugin dependency was in my pom.xml OK  (as supposed)

I added the dependency indicated in the how to, so:

<!-- GeoTools layers dependencies -->
<dependency>
   <groupId>org.postgis</groupId>
   <artifactId>postgis-jdbc</artifactId>
   <version>1.1.6</version>
</dependency>
<dependency>
   <groupId>postgresql</groupId>
   <artifactId>postgresql</artifactId>
   <version>8.1-407.jdbc3</version>
</dependency>
<dependency>
   <groupId>org.geotools</groupId>
   <artifactId>gt-postgis</artifactId>
</dependency>

I edited web.xml to point to the configuration file for the example with geotools

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            <!-- framework context -->
            classpath:org/geomajas/spring/geomajasContext.xml
            WEB-INF/example/geotools/applicationContext.xml
            WEB-INF/example/geotools/layerRoads.xml
            WEB-INF/example/geotools/layerOsm.xml
        </param-value>
    </context-param>

Then I edited the layerRoads.xml and the ApplicationContext.xml files following the structure of my spatial table that is called "italy_street"

I edited the Application.java file with the correct name for the application, the MainMap and the OverviewMap that are different from the ones in the default sample

In layerRoads.xml I edited the name of the fields for the id field, and the geometry field and one or two more attributes.

    <bean class="org.geomajas.configuration.FeatureInfo" name="layerRoadsFeatureInfo">
        <property name="dataSourceName" value="italy_street" />
        <property name="identifier">
            <bean class="org.geomajas.configuration.PrimitiveAttributeInfo">
                <property name="label" value="gid" />

                <property name="editable" value="true" />
            </bean>
        </property>
        <property name="attributes">
            <list>
                <bean class="org.geomajas.configuration.PrimitiveAttributeInfo">
                    <property name="label" value="Type" />
                    <property name="name" value="type" />
                    <property name="editable" value="true" />
                    <property name="identifying" value="true" />
                    <property name="type" value="STRING" />
                    <property name="validator">
                        <bean class="org.geomajas.configuration.validation.ValidatorInfo">
                            <property name="toolTip" value="i18n:road.label.Tooltip" />
                        </bean>
                    </property>
                </bean>
                <bean class="org.geomajas.configuration.PrimitiveAttributeInfo">
                    <property name="label" value="Nome" />

                    <property name="type" value="STRING" />
                </bean>
            </list>
        </property>
    </bean>
    <bean name="layerRoadsInfo" class="org.geomajas.configuration.VectorLayerInfo">
        <property name="layerType" value="MULTILINESTRING" />
        <property name="crs" value="EPSG:4326" />
        <property name="maxExtent">
            <bean class="org.geomajas.geometry.Bbox">
                <property name="x" value="6.6149087" />
                <property name="y" value="36.6527781" />
                <property name="width" value="11.8976246" />
                <property name="height" value="10.4424119" />
            </bean>
        </property>
        <property name="featureInfo" ref="layerRoadsFeatureInfo" />
        <property name="namedStyleInfos">
            <list>
                <ref bean="layerRoadsStyleInfo" />
            </list>
        </property>
    </bean>

In ApplicationContext.xml I edited the appDataSource, that is the connection to postgres, as follow:

    <bean name="appDatastore" class="org.geomajas.layer.geotools.DataStoreFactory" factory-method="create">
        <constructor-arg>
            <map>
                <entry key="host" value="localhost" />
                <entry key="schema" value="public" />
                <entry key="user" value="username" />
                <entry key="passwd" value="****" />
                <entry key="database" value="ggis" />
                <entry key="port" value="5432" />
                <entry key="dbtype" value="postgis" />
            </map>
        </constructor-arg>
    </bean>

If I leave the connection like this I get the following errors:

If I leave the appDataSource without the parameter "host" I can deploy the application, it loads but when I zoom in where there is my postgis layer I get the following errors:
