Workflow external tasks and CSSDK

Bowker

TS 6.5
win2003

Using a Perl external app and spawning OS commands to perform operations is quite easy, the external commands (from what I can tell) run as SYSTEM.

I'm now trying to convert those tasks into Java apps and utilize CSSDK to perform specific operations. Unfortunately in order to do anything useful in CSSDK you need to create a CSClient which requires a username, password and role.

Any ideas how I can utilize CSSDK from an externaltask without a Username/Password/Role?

Hi Dan,
Unfortunately this feature is not present in the current CSSDK SOAP client. However, if you are running the CS application on the same box as the TeamSite, you could potentially use the CSSDK's CSLocalFactory instead of the CSSOAPFactory. In this local mode, there is a method called CSLocalFactory.getClientForTrustedUser call that you can use in order to get a CSClient without giving a password (I assume that is your main goal). For this method to work, the Java application needs to be run as a user that has read permissions on the <iw-home>/private/etc/passphrase file, and has to have write permissions on the "temp" location (on Windows, it is the TEMP env variable, and on Unix, it is /tmp).

Please note that this method is not available in versions earlier than TS6.5.

If you do not want to use the local factory, you could achieve the same purpose by running an automated CS application every 24 hours to get a session string for a user you want to run your main CS application as, and store it in a commonly accessible location, and use the session string to get CSClient. I'll give more details that might make it more clear why this is required. A CSClient object is essentially an encapsulation of the session string for a particular user (among other things). The default expiration time for the session string is 24 hours, and can be changed in iw.cfg. Once you obtain a session string for a user, it can be used to obtain CSClient objects any number of times during the 24 hour period without a problem, as long as you do not call CSClient.endSession().

The rationale behind allowing only CSLocalFactory to be able to do logins without password, is similar to the way perl scripts were allowed to use CLTs to do TS jobs.

Hope this helps.
