Passing a param to a JavaScript in Java using myApp.doScript

You are generally going about this correct. You don't show the code for creating the argSeq so I don't know what is in there.

I created the following script:

name = app.scriptArgs.get("name");
app.consoleout("Hello, " + name);

and then ran it using the following command line:

sampleclient -host localhost:5000 ~/Desktop/test.js name=mike

Each argument should be a name, value pair. I think an array of 2. It looks like to me that the java code is not creating a name for each value.

It should probably be something like this:

String param1[2] = new String({"param1", "TestParam"});
...

There are two ways to access parameters passed to your script.

1) If your script is run by calling RunScript (via SOAP), parameters are stored in app.scriptArgs, and are passed to the script in an array of name/value pairs.
Called using SampleClient:
sampleclient -host localhost:12345 c:\myScript.jsx arg0=5
Accessing params in the script:
var myVal = app.scriptArgs.getValue("arg0");

2) If you are calling your script using doScript (via Scripting or Java), your parameters are accessed using the variable "arguments", and are passed to the script in a flat array.
Called from Java:
VariableType [] vtArgs = new VariableType[1];
vtArgs[0] = VariableTypeUtils.createString("5");
OptVariableTypeSeq argSeq = OptArg.makeVariableTypeSeq(vtArgs);

VariableType returnValue = myApp.doScript(
VariableTypeUtils.createFile("c:\myScript.jsx"),
OptArg.makeScriptLanguageEnum(kScriptLanguageJavascript.value),
argSeq,
OptArg.noUndoModesEnum(),
OptArg.noString());

Accessing params in the script:
var myVal = arguments[0];

Here is a script you can use to test where your parameters are stored (note that arguments is undefined if script is run via SOAP):

var myScriptArgs = "";
// replace "arg0" with the name of your parameter
if (app.scriptArgs.isDefined("arg0")) {
myScriptArgs = "arg0 = " + app.scriptArgs.getValue("arg0");
}
var myArguments = "";
for ( i = 0; i < arguments.length; i++) {
myArguments = myArguments + " arguments[" + i + "] = " + arguments[i];
}

var theResult = "ScriptArgs = " + myScriptArgs + " arguments = " + myArguments;

theResult; // returns value of theResult to caller

When calling a script from Java using doScript, your parameters are sent in an array of values - no names are associated with the parameters. To access the parameters in your script, you access the "arguments" array like this:

var arg0 = arguments[0];
var arg1 = arguments[1];

You probably need to rewrite your script to use the "arguments" array instead of scriptArgs.
