Can we have the REST web services or any Pega features can trigger Windows SCP command to send a product jar from Windows to Linux.

Pega 7.1.9 and later ship with native one-way SFTP support. As you planned to use SCP, your Linux machine's SSH service probably already supports SFTP, which is an extension to SSH, just like SCP.
SFTP achieves the same goal as SCP - transferring file data over a secure channel.
The SFTP call would be made using the "Connect-FTP" method in an Activity, which you could run as part of a REST Service call or any other procedure in your Pega application.
If you're not ready to upgrade, we do provide a guide for attempting to build your own SFTP solution in Pega (https://docs-previous.pega.com/configuring-custom-sftp-and-ftps-implementations-pega-applications) but this is much more difficult than using the out-of-the-box feature in later versions of Pega 7.

Hi HOULJ,
Thank you for your response.We have started implementing custom FTP Secure (FTPS) steps in the article provided above.
The java code mentioned doesnt say anything about the destination path into which the file should be copied.Please help.

The method cd() under ChannelSftp should help.

public void cd(String path) throws SftpException

HI Team,
Thank you for the recommendations.
We could find connect-FTP method @ PEGA 718.It does mean we could avoid using the java code and importing the commons apache jar file ?
In addition,we are facing the following FTP server error (Service reply :SSH-2.0-OpenSSH_6.7 ).PFA for the screenshots.

Please review my first response to your post.
SFTP is an officially supported protocol for Connect-FTP in Pega 7.1.9 and later. Pega 7.1.8 only supports the non-compatible "FTP" and "FTPS" protocols. If you would like the out-of-the-box SFTP support, you should upgrade to the newest Pega release.
The response you are getting is expected. The server is saying "I am an SSH server" when you are trying to open a connection to it. SFTP is an extension to SSH.

Hi Team,
While trying to save an Activity with a java step (Custom SFTP implementation),the below mentioned compilation error has been observed.
Test compilation failed: ----------
1. ERROR in \Rule_Obj_Activity_Rule_Obj_Activity_Devops_SFTP_Action_20180214T212531_769_GMT.java (at line 157)
String localFile = tools.getParamValue("D:\PEGA_TEMP\DEVOPS\PegaRULES_Extract_Marker.txt");
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Invalid escape sequence (valid ones are \b \t \n \f \r \" \' \\ )
----------
1 problem (1 error)
Compile failed.
jsch-0.1.54 version downloaded from SourceForge has been installed in our lib path : D:\Apache\Tomcat\7.0.57\lib and the compiler/defaultPaths has been added followed by a restart.
Please find the attachment for additional details regarding the java code and the activity.

Could you explain what you're attempting to do with this line:
String localFile = tools.getParamValue("D:\PEGA_TEMP\DEVOPS\PegaRULES_Extract_Marker.txt");
I do not understand why you would do tools.getParamValue here. That gets a value off of the current Parameter Page, using some key that is already on the Map.
If you just want to set the path, use forward slashes ('/') or escape your backslashes ("\\").
String localFile = "D:/Temp/MyFile.txt"
OR
String localFile = "D:\\Temp\\MyFile.txt"
Update: after reviewing your document I see that you have used "getParamValue" when defining every String variable. This is incorrect, and you will get null/empty values for every one of those Strings.

I reviewed your doc file with the code in it.
There are multiple errors including these erroneous '*' characters.
The first step is to remove those. You may stop getting compilation errors after that.

Followed up your recommendations,but still facing the following error "com.jcraft cannot be resolved to a type".
Please find the attachment for the latest java code along with the error messages.

I have placed the jsch-0.1.54.jar (downloaded from sourceforge) in to the lib path (D:\Apache\Tomcat\7.0.57\lib) of our tomcat server followed by a restart.In addition, I have added a DSS compiler/defaultPaths as well.
Not sure what else to be taken care to import the above mentioned library properly.

sure.Could you please provide some specifications about the database server path into which the library should be imported.
