Re: How to start and use ignite in Tomcat

[Andrey Gura]

Hi,

In order to start clint node you should just execute code like this:

Ignition.setClientMode(true);
Ignition.start();

In this case client node with default configuration will be started. Of
course you can provide own IgniteConfiguration programatically:

IgniteConfiguration cfg = new IgniteConfiguration();
cfg.setClientMode(true);
// ... other settings
Ignition.start(cfg);

or using Spring configuration files:

<beans xmlns="http://www.springframework.org/schema/beans";
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
       xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans.xsd";>

    <bean id="ignite.cfg"
class="org.apache.ignite.configuration.IgniteConfiguration">

        <property name="clientMode" value="true"/>

        <!-- Explicitly configure TCP discovery SPI to provide list of
initial nodes. -->
        <property name="discoverySpi">
            <bean
class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
                <property name="ipFinder">
                    <!--
                        Ignite provides several options for automatic
discovery that can be used
                        instead os static IP based discovery. For
information on all options refer
                        to our documentation:
http://apacheignite.readme.io/docs/cluster-config
                    -->
                    <!-- Uncomment static IP finder to enable static-based
discovery of initial nodes. -->
                    <!--<bean
class="org.apache.ignite.spi.discovery.tcp.ipfinder.vm.TcpDiscoveryVmIpFinder">-->
                    <bean
class="org.apache.ignite.spi.discovery.tcp.ipfinder.multicast.TcpDiscoveryMulticastIpFinder">
                        <property name="addresses">
                            <list>
                                <!-- In distributed environment, replace
with actual host IP address. -->
                                <value>127.0.0.1:47500..47509</value>
                            </list>
                        </property>
                    </bean>
                </property>
            </bean>
        </property>
    </bean>

</beans>


If you want use JDBC drievr for connection to Ignite cluster there is no
need to create any client nodes.
