title: Set Ehcache timeout when using JTA
body: <p>I have hooked Ehcache into my JTA transaction manager (provided by Atomikos) using the setting <code>cacheConfiguration.setTransactionalMode("xa");</code>, and am receiving the following error approximately 15 seconds after my application starts up:</p>
  
  <pre><code>Caused by: net.sf.ehcache.transaction.TransactionTimeoutException: transaction [0] timed out

  <p>When my app starts for the first time it performs some initial set up within a single transaction which takes approximately 60 seconds to complete. Consequently I need to increase the 15-second timeout to be a bigger value, but cannot find where this is controlled. From looking at the Ehcache documentation it seems this should be controlled by JTA, but I've already set the default timeout for UserTransaction and TransactionManager:</p>
  
  <pre><code>@Bean
  public UserTransaction userTransaction() throws SystemException {
  
      UserTransactionImp uti = new UserTransactionImp();
      uti.setTransactionTimeout(120000);
  
      return uti;
  }
  
  @Bean(initMethod = "init", destroyMethod = "close")
  public TransactionManager transactionManager() throws SystemException {
  
      UserTransactionManager utm = new UserTransactionManager();
      utm.setForceShutdown(false);
      utm.setTransactionTimeout(120000);
  
      return utm;
  }
  </code></pre>
  
  <p>Any pointers would be appreciated.</p>
