Sequence diagram tool on ubuntu

Web is amazing, I was trying to find some good tool to create sequence diagrams on ubuntu as my writing is awful and fortunately landed onto  http://www.websequencediagrams.com/ All you need to do is write some text in the left pane like UI->Jersey:Invoke Rest api Jersey->Spring:Spawn a transaction and it would generate an image for you in right pane. Kudos to the guy who created it.

Spring query timeout or transaction timeout

If you are using spring to manage transactions then you can specify default transaction timeout using     <bean id="transactionManager"         class="org.springframework.jdbc.datasource.DataSourceTransactionManager">         <property name="dataSource" ref="dataSource" />         <property name="defaultTimeout" value="30" /> <!--30 sec--->                  </bean> or you can override the timeout in the annotation     @Transactional(readOnly = false, timeout=30) or if you are doing it programatic transactions then you can do DataSourceTransactionManager transactionManager = new DataSourceTransactionManager(dataSource); transactionManager.setDefaultTimeout(30);  or you can override the timeout for one particular transaction TransactionTemplate transactionTemplate = new TransactionTemplate(); transactionTemplate.setTimeout(30);
