Camunda - why is process engine not getting created?

I am trying to integrate the BPMN tool : camunda in my app . I have been using the camunda docs here : https://docs.camunda.org/stable/guides/getting-started-guides/spring-framework/#set-up/application-context for that purpose .
I have added the application context related information as it has been mentioned in there :
<bean id="dataSource" class="org.springframework.jdbc.datasource.TransactionAwareDataSourceProxy">
<property name="targetDataSource">
<bean class="org.springframework.jdbc.datasource.SimpleDriverDataSource">
<property name="driverClass" value="org.h2.Driver" />
<property name="url"
value="jdbc:h2:mem:process-engine;DB_CLOSE_DELAY=1000" />
<property name="username" value="sa" />
<property name="password" value="" />
</bean>
</property>
</bean>
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="processEngineConfiguration" class="org.camunda.bpm.engine.spring.SpringProcessEngineConfiguration">

<property name="dataSource" ref="dataSource" />
<property name="transactionManager" ref="transactionManager" />
<property name="databaseSchemaUpdate" value="true" />
<property name="jobExecutorActivate" value="false" />
</bean>
<bean id="processEngine" class="org.camunda.bpm.engine.spring.ProcessEngineFactoryBean">
<property name="processEngineConfiguration" ref="processEngineConfiguration" />
</bean>
<bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService" />
<bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService" />
<bean id="taskService" factory-bean="processEngine" factory-method="getTaskService" />
<bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService" />
<bean id="managementService" factory-bean="processEngine" factory-method="getManagementService" />
But during build I am getting this error :
Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'processEngine': FactoryBean threw exception on object creation; nested exception is org.camunda.bpm.engine.ProcessEngineException: Error while building ibatis SqlSessionFactory: Cause: org.xml.sax.SAXParseException; lineNumber: 95; columnNumber: 12; The content of element type "if" must match "(include|trim|where|set|foreach|choose|if)".

at org.springframework.beans.factory.support.FactoryBeanRegistrySupport.getObjectFromFactoryBean(FactoryBeanRegistrySupport.java:103) ~[spring-beans.jar:4.3.4.RELEASE]
Can someone please let me know what mistake I am making here ?
Any help will be greatly appreciated .

Camunda 7.3.0 uses mybatis 3.2.8 as per the project BOM.
You are using mybatis 3.2.2 which possibly causes a dependency version mismatch. Try updating your project mybatis dependencies to match the ones in your Camunda version.

Migrating Spring XML based app from Jboss to Tomcat to deploy in pcf

add redeliveryPolicy to Websphere MQ message

I have a Websphere MQ and a java app receiveng messages from it. I want to make redelivering system if any exceptions is thrown .
Is there a way to add redeliveryDelay in my configuration spring xml?
here's my spring configuration:

Spring Integration Atomikos transaction issue

I'm trying to integrate Atomikos transaction manager into a Spring Integration program that forwards JMS from ActiveMQ to a WebMethods ESB.
The spring integration part only retrieves JMs from local ActiveMQ broker and sends them to a distant ESB broker.
When I test the nominal case, JMS is sent well and passes through the ESB and is dispatched to the subscribers then.
When I test the case where ESB sending fails, I have an issue : the JMS is never published back. I suppose it's a transaction issue because the transaction should have been rolled back when program tried to publish on ESB broker but it seems not.
Here's my spring config :
<bean id="transactionManager"
class="org.springframework.transaction.jta.JtaTransactionManager">
<property name="transactionManager" ref="AtomikosTransactionManager" />
<property name="userTransaction" ref="AtomikosUserTransaction" />

Source and Destination are both encapsulated in XA connection factories and transactionManager handles the two transactions. Any idea what's missing ?
