Overview
This document is intended to supplement the Kuali Rice 2.1.2 Installation Guide and aid the creation of an embedded rice client application. The information on this page is targeted for the Rice 2.1.2 release.
Running a Rice client application in Embedded Mode means:
- one or more Rice modules - in particular, KEW and KIM - are executing from within the client application
- the client application has direct access to the Rice Standalone Server database
Access to the Rice Database
A Rice client application requires three schemas:
- A schema that backs the Rice Standalone Server - generally referred to as the Rice database. The client application uses this schema to store all KEW transactions and expose services on the KSB registry.
- A Rice-provisioned schema for accessing the Rice database through a role with appropriate permissions (e.g. CRUD on KEW tables, but read-only on KNS tables). Because Rice is "schema-unaware", private synonyms pointing to the objects in the Rice database are created in this schema.
- A schema that backs the Rice client tables. This is generally hosted in the client application's database. It is used primarily for managing local Rice related Quartz jobs and thus, does not require access to any other schema.
Prerequisites
- A database account with access to the Rice database
- Procure the UC Davis-specific JARs for the modules you will be embedding along with any of their associated dependencies using either of the following methods:
- Download JARs and all transitive dependencies from the Kuali Rice website Download
ucd-rice-standalone-server-impl
WAR from Artifactory , selecting the most recent version. This WAR contains all dependencies.Add . - Download JARs for the specific module from this location in the Artifactory , selecting the most recent version.
- Download JARs and all transitive dependencies from the Kuali Rice website Download
- A certificate for the machines hosting the client application that will be connecting to the Rice Standalone Server.
- See Rice Client Application Certificate Requirements for certificate details.
Rice Libraries
In Rice 1.0.x, there were only two main jars, rice-api and rice-impl

. With the modularity work there are more api jars corresponding to service apis and framework components. Additionally, the implementation module has been split (though there is still a shared implementation module as not all components of the Rice implementation have been fully modularized as of the Rice 2.x.x release). This work was done according to the design outlined at the following page: Modularity Design
The libraries and their dependencies required for the modules which your application will be using must be included in your client application. Ideally you only include the modules of rice you are using. In practice, you may need to include them all until rice's modularity work is complete. The only modules rice recommends compiling against are api & framework modules.
Below is a list of the old 1.0.3.3 libraries and their 2.x.x counterparts:

Properties Configuration
We use a simple XML configuration to declare properties as key-value pairs. For example:
Code Block | ||||
---|---|---|---|---|
| ||||
<config>
<param name="datasource.ojb.platform">Oracle9i</param>
<param name="datasource.platform">org.kuali.rice.core.framework.persistence.platform.OraclePlatform</param>
<param name="datasource.url">jdbc:oracle:thin:@ldap://oraldap1.ucdavis.edu:389/rice_test,cn=OracleContext,dc=ucdavis,dc=edu</param>
<param name="datasource.driver.name">oracle.jdbc.driver.OracleDriver</param>
<param name="datasource.pool.validationQuery">select 1 from duak</param>
<param name="datasource.pool.maxWait">30000</param>
<param name="datasource.pool.size">30</param>
<param name="datasource.pool.maxActive">50</param>
<param name="datasource.minIdle">7</param>
<param name="datasource.initialSize">7</param>
<param name="datasource.accessToUnderlyingConnectionAllowed">true</param>
<param name="datasource.username">my_db_user</param>
<param name="datasource.password">my_db_password</param>
<config>

Core Data Source Configuration
Kuali Rice uses Java Open Transaction Manager, so we declare the appropriate beans.
Code Block | ||||
---|---|---|---|---|
| ||||
<bean id="jotm" class="org.springframework.transaction.jta.JotmFactoryBean">
<property name="defaultTimeout" value="${transaction.timeout}"/>
</bean>
|
We must declare three data sources:
- A transactional data source where the local client application's Rice tables are located. This is required by JOTM.
Code Block title classpath:edu/ucdavis/myapp/config/application-data.xml borderStyle solid <bean id="dataSource" class="org.kuali.rice.core.framework.persistence.jdbc.datasource.XAPoolDataSource"> <property name="transactionManager" ref="jotm" /> <property name="driverClassName" value="${datasource.driver.name}" /> <property name="url" value="${datasource.url}" /> <property name="maxSize" value="${datasource.pool.size}" /> <property name="minSize" value="${datasource.initialSize}" /> <property name="maxWait" value="${datasource.pool.maxWait}" /> <property name="validationQuery" value="${datasource.pool.validationQuery}" /> <property name="username" value="${datasource.username}" /> <property name="password" value="${datasource.password}" /> </bean>
- A non-transactional data source pointing to those same Rice tables. This is required by Quartz.
Code Block title classpath:edu/ucdavis/myapp/config/application-data.xml borderStyle solid <bean id="nonTransactionalDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="url" value="${datasource.url}"/> <property name="username" value="${datasource.username}"/> <property name="password" value="${datasource.password}"/> <property name="driverClassName" value="${datasource.driver.name}" /> <property name="initialSize" value="${datasource.initialSize}" /> <property name="minIdle" value="${datasource.minIdle}" /> <property name="maxActive" value="${datasource.maxActive}" /> <property name="maxWait" value="${datasource.maxWait}" /> <property name="validationQuery" value="${datasource.validationQuery}" /> <property name="testOnBorrow" value="${datasource.testOnBorrow}" /> <property name="testOnReturn" value="${datasource.testOnReturn}" /> <property name="testWhileIdle" value="${datasource.testWhileIdle}" /> <property name="accessToUnderlyingConnectionAllowed" value="${datasource.accessToUnderlyingConnectionAllowed}" /> </bean>
Tip To take advantage of pooling capabilities,
testOnBorrow
should be set totrue
. - A transactional data source pointing to the database of the Rice Standalone Server.
Code Block title classpath:edu/ucdavis/myapp/config/application-data.xml borderStyle solid <bean id="standaloneDataSource" class="org.kuali.rice.core.framework.persistence.jdbc.datasource.XAPoolDataSource"> <property name="transactionManager" ref="jotm" /> <property name="driverClassName" value="${standalone.datasource.driver.name}" /> <property name="url" value="${standalone.datasource.url}" /> <property name="maxSize" value="${standalone.datasource.pool.size}" /> <property name="minSize" value="${standalone.datasource.initialSize}" /> <property name="maxWait" value="${standalone.datasource.pool.maxWait}" /> <property name="validationQuery" value="${standalone.datasource.pool.validationQuery}" /> <property name="username" value="${standalone.datasource.username}" /> <property name="password" value="${standalone.datasource.password}" /> </bean>
KEW Service Configuration
As of 1.0.1.1-UCD-SR1d, Rice applications will no longer encrypt workflow document content. This is accomplished by disabling encryption using the out-of-the-box non-encryption implementation (org.kuali.rice.core.impl.encryption.NoEncryptionEncryptionServiceImpl
). It is instantiated by declaring classpath:edu/ucdavis/kuali/rice/kew/config/ucd-kew-service.xml
in the Spring context.
Consequently, the encryption.key
property is no longer required.
KRAD Service Configuration
- Maintenance Document Encryption
- As of 1.0.1.1-UCD-SR1d, Rice applications will no longer encrypt maintenance document content.
- This is accomplished by disabling encryption using the out-of-the-box non-encryption implementation (
org.kuali.rice.core.impl.encryption.NoEncryptionEncryptionServiceImpl
). - Disable encryption by declaring the
classpath:edu/ucdavis/kuali/rice/krad/config/ucd-krad-service.xml
Spring file (see UCD Spring Bean Configuration). - Remove (or comment out) references to the
encryption.key
property (e.g. in rice-config.xml, kc-config.xml, embedded-client-config.xml, etc.).
UCD Spring Bean Configuration
Declare the UCD-implemented Rice services:
Code Block | ||||
---|---|---|---|---|
| ||||
<param name="rice.kr.additionalSpringFiles">classpath:edu/ucdavis/kuali/rice/krad/config/ucd-krad-service.xml</param>
<param name="rice.kew.additionalSpringFiles">classpath:edu/ucdavis/kuali/rice/kew/config/ucd-kew-service.xml</param>
|
- If you're using Spring's
ContextLoaderListener
, declare them inweb.xml
<exclusion>Code Block title src/main/webapp/WEB-INF/web.xml borderStyle solid <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value> ... classpath:edu/ucdavis/kuali/rice/kim/config/ucd-krad-service.xml classpath:edu/ucdavis/kuali/rice/kew/config/ucd-kew-service.xml
... </param-value> </context-param>
CoreConfigurer Bean Configuration
Finally, we declare the coreConfigurer
bean and inject all of the core data source beans.
Code Block | ||||
---|---|---|---|---|
| ||||
|
...
<bean id="coreConfigurer" class="org.kuali.rice.core.impl.config.module.CoreConfigurer"> <property name="dataSource" ref="dataSource" /> <property name="nonTransactionalDataSource" ref="nonTransactionalDataSource" /> <property |
...
name="serverDataSource" ref="standaloneDataSource"/> <property name="transactionManager" ref="jotm" /> <property name="userTransaction" ref="jotm" /> < |
...
/bean>
<bean id="ksbConfigurer" class="org.kuali.rice.ksb.messaging.config.KSBConfigurer" />
<bean id="kradConfigurer" class="org.kuali.rice.krad.config.KRADConfigurer" />
<bean id="coreServiceConfigurer" class="org.kuali.rice.coreservice.impl.config.CoreServiceConfigurer" />
<bean id="kimConfigurer" class="org.kuali.rice.kim.config.KIMConfigurer" />
<bean id="kewConfigurer" class="org.kuali.rice.kew.config.KEWConfigurer" />
<bean id="kenConfigurer" class="org.kuali.rice.ken.impl.config.KENConfigurer" />
<bean id="edlConfigurer" class="org.kuali.rice.edl.impl.config.EDLConfigurer" />
<bean id="krmsConfigurer" class="org.kuali.rice.krms.config.KRMSConfigurer" />
<bean id="locationConfigurer" class="org.kuali.rice.location.impl.config.LocationConfigurer" />
