My Postfix is running and its configuration is the default.
Also, port 25 is in listening status
And I'm able to connect using telnet localhost 25
Source code is at https://bitbucket.org/saavedrah_/javamail/src/master/
Thank you
In my build.gradle I had a reference to these two libraries
implementation 'javax.mail:javax.mail-api:1.6.2'
implementation 'javax.mail:mail:1.5.0-b01'
when removing the javax.mail-api reference the mail was sent without any problem.
Thank you
I am trying to follow SQS example from this repo https://github.com/jonyfs/spring-boot-jms-sqs.
I have upgraded Spring boot to 2.1.0-RELEASE and cloud dependency to Greenwich.M1. The code is working fine, producing messages and consuming it
But I keep getting below exception. I have tried with different dependencies combinations and adding clientconfiguration also.

Bad file descriptor are usually thrown when you use a closed socket. Typically AWS SDK will automatically retry connection errors like this, which is why you're not seeing any actual impact - on the retry it uses a fresh connection.
If they're happening once in a while, just ignore them. If they happen frequently, try playing with your connection settings in the ClientConfiguration to see what reduces them.
I also strongly suggest validating that you don't have some sort of classpath conflict where there are multiple versions of the same classes on your classpath - "interesting" things can happen at runtime due to how the classloader chooses which one to use.

I tried reinstall all IDE (with removing cache, setting in Library dir), but it doesn't help me.
Any ideas?
p.s ssh work fine with this server in console, i have this problem only in IDE, and only with sftp protocol.
I found solution in this ticket youtrack.jetbrains.com/issue/WI-12925#comment=27-580440
It's the same problem with known_hosts file.
Solution:
Try to backup and remove .ssh/known_hosts file, and recreate it adding hosts when needed.
I'm trying to implement the RMI Compute PI tutorial found on the Sun/Oracle website here. The server is located on an Amazon windows EC2 Server. The client is located on my personal computer at home. Just to keep things simple, I have disabled the firewall on the server and open all the port on the EC2 security group. I can ping the machine, have access to files, etc... My aim is just to have a basic RMI program worked on AWS. I will oversee security issues later.
Lauching the server is not a problem. And it's correctly bound to the RMI Registry. I'm using the following command to launch it :
java -Djava.security.manager -Djava.security.policy=C:\AWSTest\security.policy -Djava.rmi.server.codebase=file:/C:/AWS/Sources/sun-rmi-tutorial-server/bin/ file:/C:/AWS/Sources/sun-rmi-tutorial-common/bin/ -classpath C:\AWS\Sources\sun-rmi-tutorial-server\bin;C:\AWS\Sources\sun-rmi-tutorial-common\bin engine.ComputeEngine ec2-XX-XX-XX-XXX.ap-southeast-1.compute.amazonaws.com
The RMI registry is started on the server side.
I have declared a new security manager on the server side System.setSecurityManager(new RMISecurityManager())
I'm using a security.policy file where I'm granted all permission.
When I'm launching the client side, on my local computer, I'm ending with an UnmarshalException:
ComputePi exception: error unmarshalling return; nested exception is:
java.lang.ClassNotFoundException: engine.ComputeEngine_Stub

Do you have any suggestions of what is wrong ? Why can't the client find the correct Stub ? I'm using Eclipse Juno, Genady RMI Plugin and Java 1.7.0_07.
Thanks for your help
EDIT 1 :
The Java workspace is organized around 3 projects : the Client side, the Server Side and a Common project where both the server and the client share classes.
I can read the remote registry from my local computer. The RMI plugin can connect remotely to the server and inspect the registry.
If instead of making 3 projects I put all the classes under the same project, everything is working fine... But I notice that no stubs where generated (or needed).
If, on the client side, I'm putting a reference in the classpath to the server classes (everything being build locally), i have a connection timeout error instead of the unmarshalling error.

I compile it before running on freeBSD. I think that JVM installed normally.
The same file runs on windows. Can anyone help?
