Set the network security in the EC2 configuration to allow MongoDb traffic through to your DB box, the default is 27017.
In case anyone comes by (because I did) I was stuck on this same problem of mongodb connecting on local but not on my ec2 server.. for hours.. here is the solution and it's very simple.
When you created the MongoDB cluster, you added your computer's IP address to the white list. You need to grab EC2 Instance's 'IPv4 Public IP' and add that to to the white list as well.

I'm getting this exception in production. Things are quiet for weeks at a time and then we get a "rash" of them all of a sudden:
Caused by: org.springframework.jdbc.CannotGetJdbcConnectionException:
Failed to obtain JDBC Connection; nested exception is
java.sql.SQLTransientConnectionException: HikariPool-1 - Connection is
not available, request timed out after 1031ms.
STEPS TAKEN TO INVESTIGATE THE PROBLEM:
This symptom has well-known possible causes, which I have checked:
JdbcTemplate is being used correctly, checked: Spring jdbctemplate is it required to close the connection
Using try-with-resource to ensure Connections are closed, checked: Hikari Pool Connection is not available Error
Database server can support the load, checked (server not busy at all, checked top and pg_activity and netstat -- really not much is going on): Hikari connection pool, Connection is not available
What else could be causing this?

I am new to camel and I am attempting to write an app that bridges Websphere MQ and Active MQ on JBoss EAP 7. The app deploys successfully works, I can drop messages on the Websphere queue, and it gets picked up by Active MQ. However I see error messages in the log showing it is attempting to use a connection after it is open.

Its a simple app, trying to determine what I'm missing.
I found this JBossDeveloper bug "JBEAP-2344: UserTransaction commit(), rollback() closes connection in Websphere MQ 7.5" which looks like it describes your issue and has comments pointing to documentation update "JBEAP-3535: Documentation: Add note about connection close on commit() and rollback() to Deploy the WebSphere MQ Resource Adapter subchapter".
Could you please add a note, that setting tracking="false", solves
problem with WebSphere MQ 7.5 and 8, where method commit() or
rollback() on UserTransaction closes any JMS connections which was
part of this transaction. This part is related to documenting known
limitation of WebSphere MQ in
JBEAP-3142.
I am using Activiti Explorer version 5.17, I want to send mail by using Mail Task but it not work.

When i run process, nothing is display in console, and it not work.
Thanks for any help. :)
I tried something but in the version 5.18(I'm not sure if can be applicable on your version), try to configure those thing on activiti-custom-context.xml(placed in activiti-explorer\WEB-INF\classes). Also you can configure your db connection, for example.
First uncomment the beans and then fill your db information in the bean with the id "dataSource".
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/database" />
<property name="username" value="user" />
<property name="password" value="password" />
<property name="defaultAutoCommit" value="false" />
</bean>
To configure the email add some properties to the bean with the id "processEngineConfiguration"
<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
<property name="dataSource" ref="dataSource" />
<property name="transactionManager" ref="transactionManager" />
<property name="databaseSchemaUpdate" value="true" />
<property name="jobExecutorActivate" value="true" />
<property name="enableDatabaseEventLogging" value="true" />
<property name="customFormTypes">
<list>
<bean class="org.activiti.explorer.form.UserFormType"/>
<bean class="org.activiti.explorer.form.ProcessDefinitionFormType"/>
<bean class="org.activiti.explorer.form.MonthFormType"/>
</list>
</property>
<property name="mailServerUseTLS" value="true" /><!--This is important if you use Gmail as your hoster -->
<property name="mailServerHost" value="smtp.gmail.com" />
<property name="mailServerPort" value="587" />
<property name="mailServerUsername" value="my#host.com" />

I'm using Eclipse with Maven, in myBatis-config.xml I have the following codes. The H2 part of the code works as I can connect to H2 with my program and access the database. The Oracle part of my code doesn't work. I'm using ORACLE DATABASE XE 11.2, application express with a workspace: test, username: name, password: 123. When I run a testing class in Eclipse, I could pass the H2 tests, but when I run the same test using oracle instead, it gets an error. "Error selecting key or setting result to parameter object.

Hello reading the documentation from the official site of MyBatis I could obtain the following information:
In case of using the multi-db feature you will need to inform the databaseIdProvider property in the following way:

NOTE Since 1.3.0, configuration property has been added. It can be specified a Configuration instance directly without MyBatis XML configuration file. For example:

I was trying to share My in-memory jobRepository to the jobExplorer. But it throws an error as,
Nested exception is
org.springframework.beans.ConversionNotSupportedException:
Failed to convert property value of type '$Proxy1 implementing
org.springframework.batch.core.repository.JobRepository,org.
springframework.aop.SpringProxy,org.springframework.aop.framework.Advised'
to required type
Even i tried putting '&' sign before jobRepository when passing to jobExplorer for sharing.But attempt end in vain.
I am using Spring Batch 2.2.1
Is the dependency for jobExplorer is only database not in-memory?
Definition is,
<bean id="jobRepository"
class="com.test.repository.BatchRepositoryFactoryBean">
<property name="cache" ref="cache" />
<property name="transactionManager" ref="transactionManager" />
</bean>
<bean id="jobOperator" class="test.batch.LauncherTest.TestBatchOperator">
<property name="jobExplorer" ref="jobExplorer" />
<property name="jobRepository" ref="jobRepository" />
<property name="jobRegistry" ref="jobRegistry" />
<property name="jobLauncher" ref="jobLauncher" />
</bean>
<bean id="jobExplorer" class="test.batch.LauncherTest.TestBatchExplorerFactoryBean">
<property name="repositoryFactory" ref="&jobRepository" />
</bean>
<bean id="transactionManager"
class="org.springframework.batch.support.transaction.ResourcelessTransactionManager" />
<bean id="jobLauncher" class="com.scb.smartbatch.core.BatchLauncher">
<property name="jobRepository" ref="jobRepository" />
</bean>
<!-- To store Batch details -->
<bean id="jobRegistry" class="com.scb.smartbatch.repository.SmartBatchRegistry" />
<bean id="jobRegistryBeanPostProcessor"
class="org.springframework.batch.core.configuration.support.JobRegistryBeanPostProcessor">
<property name="jobRegistry" ref="jobRegistry" />
</bean>
<!--Runtime cache of batch executions -->
<bean id="cache" class="com.scb.cache.TCRuntimeCache" />
thanks for your valuable inputs.
But I used '&' before the job repository reference, which allowed me to use it for my job explorer as a shared resource.
problem solved.
kudos.
Usually you have to wire interface instead of implementation.
Else, probably, you have to add <aop:config proxy-target-class="true"> to create CGLIB-based proxy instead of standard Java-based proxy.
Read Spring official documentation about that
