what don't you use External task for that?

It is an external Task. Starting with 6.7.1 you can use a URL in addition to the traditional External Task Scripts
as a "command" Attribute Value. This feature allows you to run custom Servlets on your TeamSite server host or
on a remote host. Executed Class normally implements "CSURLExternalTask" Interface.

Is this the correct syntax?Can anybody please help me out with the exact syntax.A sample might be of great help.

In the External task, put the following in command:

$IW-HOME/tools/java/bin/java -cp classpath package.classname

Replace the

classpath

with your class path, replace the

package.classname

with your package and class name.

It may seems a minor thing - but most programming languages do not allow hyphens in their variable names, so

$IW-HOME

is really the same as

$IW

plus the string

"-HOME"

. I assume you actually meant

$IW_HOME

(underscore, not hyphen) which is a TeamSite System Variable (p. 65 WFM 1.0.1.0 manual)

1. I think it should be $IW_SERVER (and not $IW-SERVER) if at all - or just use your server name or localhost.
2. It should be ClassName and not className.

You can pass variables/params with something like this: $IW_SERVER/iw-cc/urlexternaltask?param1=value1. Alternatively you can set job/task level variables and retrieve them in your Java class.

Hi, vpatel
It's great that it works now.
I switch to the URL task, and define URL http://servername/iw-cc/ urlexternaltask where servername is the local host on which the workflow is being run. Then add the value ClassName as a variable to the urltask
Now it can call execute method automatically.
thx for your continuous help and concerning.
