Deploying Web Flow on JBoss / Wildfly
Two modules need to be configured for JBoss / Wildfly:
- Web Flow - the main Web Flow application
- Next Step - a backend service for Web Flow which manages operation steps and authentication methods
Optionally Web Flow Client application and TPP Engine application can be also configured.
JBoss Deployment Descriptor
Web Flow contains the following configuration in jboss-deployment-structure.xml file for JBoss / Wildfly:
<?xml version="1.0"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.3">
<deployment>
<exclude-subsystems>
<!-- disable the logging subsystem because the application manages its own logging independently -->
<subsystem name="logging" />
</exclude-subsystems>
<dependencies>
<module name="com.wultra.powerauth.webflow.conf" />
</dependencies>
<local-last value="true" />
</deployment>
</jboss-deployment-structure>
Similarly, Next Step contains the following configuration in jboss-deployment-structure.xml file for JBoss / Wildfly:
<?xml version="1.0"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.3">
<deployment>
<exclude-subsystems>
<!-- disable the logging subsystem because the application manages its own logging independently -->
<subsystem name="logging" />
</exclude-subsystems>
<dependencies>
<module name="com.wultra.powerauth.nextstep.conf" />
</dependencies>
<local-last value="true" />
</deployment>
</jboss-deployment-structure>
Optionally, TPP engine contains the following configuration in jboss-deployment-structure.xml file for JBoss / Wildfly:
<?xml version="1.0"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.3">
<deployment>
<exclude-subsystems>
<!-- disable the logging subsystem because the application manages its own logging independently -->
<subsystem name="logging" />
</exclude-subsystems>
<dependencies>
<module name="com.wultra.powerauth.tpp-engine.conf" />
</dependencies>
<local-last value="true" />
</deployment>
</jboss-deployment-structure>
Optionally, Web Flow Client contains the following configuration in jboss-deployment-structure.xml file for JBoss / Wildfly:
<?xml version="1.0"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.3">
<deployment>
<exclude-subsystems>
<!-- disable the resource-adapters subsystem to prevent the application's HSQLDB driver
from being included in application server JDBC drivers -->
<subsystem name="resource-adapters" />
<!-- disable the logging subsystem because the application manages its own logging independently -->
<subsystem name="logging" />
</exclude-subsystems>
<dependencies>
<module name="com.wultra.powerauth.webflow-client.conf" />
</dependencies>
<local-last value="true" />
</deployment>
</jboss-deployment-structure>
The deployment descriptor requires configuration of the com.wultra.powerauth.webflow.conf and com.wultra.powerauth.nextstep.conf modules.
Optionally configure also the com.wultra.powerauth.tpp-engine.conf and com.wultra.powerauth.webflow-client.conf modules.
JBoss Module for Web Flow Configuration
Create a new module in PATH_TO_JBOSS/modules/system/layers/base/com/wultra/powerauth/webflow/conf/main and PATH_TO_JBOSS/modules/system/layers/base/com/wultra/powerauth/nextstep/conf/main .
The files described below should be added into this folder.
Main Module Configuration
The module.xml configuration is used for module registration. It also adds resources from the module folder to classpath.
Web Flow module configuration:
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="com.wultra.powerauth.webflow.conf">
<resources>
<resource-root path="." />
</resources>
</module>
Web Flow Client module configuration:
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="com.wultra.powerauth.webflow-client.conf">
<resources>
<resource-root path="." />
</resources>
</module>
Next Step module configuration:
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="com.wultra.powerauth.nextstep.conf">
<resources>
<resource-root path="." />
</resources>
</module>
Logging Configuration
Use the logback.xml file to configure logging, for example:
<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="30 seconds">
<property name="LOG_FILE_DIR" value="/var/log/powerauth" />
<property name="LOG_FILE_NAME" value="webflow" />
<property name="INSTANCE_ID" value="${jboss.server.name}" />
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${LOG_FILE_DIR}/${LOG_FILE_NAME}-${INSTANCE_ID}.log</file>
<immediateFlush>true</immediateFlush>
<rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<fileNamePattern>${LOG_FILE_DIR}/${LOG_FILE_NAME}-${INSTANCE_ID}-%d{yyyy-MM-dd}-%i.log</fileNamePattern>
<maxFileSize>10MB</maxFileSize>
<maxHistory>5</maxHistory>
<totalSizeCap>100MB</totalSizeCap>
</rollingPolicy>
<encoder>
<charset>UTF-8</charset>
<pattern>%d{ISO8601} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<logger name="com.wultra" level="INFO" />
<logger name="io.getlime" level="INFO" />
<root level="INFO">
<appender-ref ref="FILE" />
</root>
</configuration>
For Next Step you can use the same configuration, just change the variable LOG_FILE_NAME.
Application Configuration
The application-ext.properties file is used to override default configuration properties, for example:
# Database Configuration
spring.datasource.jndi-name=java:/jdbc/powerauth
# PowerAuth Client configuration
powerauth.service.url=http://[host]:[port]/powerauth-java-server/rest
Mind that you should specify spring.datasource.jndi-name to use the application server datasource (its declaration is out of the scope of this guideline).
When configure spring.datasource.url, the hikari connection pool is used.
Spring Boot running on WildFly or JBoos initializes JtaTransactionManager.
Web Flow Spring application uses the ext Spring profile which activates overriding of default properties by application-ext.properties.
You need to configure separate application-ext.properties files for Web Flow and Next Step in each module.
