You can use script in several locations of lsc.xml:

  • <mainIdentifier>

  • <conditions>

  • <dataset>

Supported scripting language are:

  • Javascript (JVM interpretor) (js:)

  • Javascript (Rhino interpretor) (rjs:), also with debugger (rdjs:)

  • Groovy (gr:)

LSC objects

You have access to LSC objects in script:

  • srcBean: source entry

  • dstBean: destination entry


Some variables are provided by LSC and can be used in script:

  • nocreate: dry run flag for create

  • noupdate: dry run flag for update

  • nodelete: dry run flag for delete

  • nomodrdn: dry run flag for modrdn

External files

You can load an external file and use functions inside your LSC script, thanks to <scriptInclude> markup.

For example, at the end of a task definition, insert:






You can add several files, by adding other <string> values

The file test.js must be in the configuration directory, else you should set the relative path (for example ../test.js) if the file is in another location.

Dummy example:

function test() {
        return "test-->";

Then this method can be used in a dataset, for example:



If the extension is .js, it is assumed to be a javascript file. It the extension is .groovy, .gvy .gy or .gsh, it is assumed to be a groovy file.


You can launch Rhino debugger by using rdjs: instead of rjs: or js:. This will open this window:



Launch LSC in a single thread (option -t 1) to avoid multiple debug windows.
