setVariableData to assign a Invoke Input Variable Collection from java embedding

Question

I am using the below line in JAVA Embedding to assign value to a BPEL Invoke DB adapter input variable.

setVariableData("S2C_insert_InputVariable","TmpInvStoc3Collection","/ns8:TmpInvStoc3Collection/ns8:TmpInvStoc3/ns8:batchid","12345"); 

Now i want to put this statement in a while loop within java and want to repeat this for n iterations. I want to place a loop variable in the collection but I dont know how to do this.

I am looking for something like below.

setVariableData("S2C_insert_InputVariable","TmpInvStoc3Collection","/ns8:TmpInvStoc3Collection/ns8:TmpInvStoc3[$loop_variable]/ns8:batchid","12345");

Please let me know how to achieve this

Answer 1

This is based on the assumption that value is a function of i and cannot be calculated in the BPEL.

String qry = "";
for (int i = 0; i < n; i++)
{
    value = SomeFunctionThatRequiresJavaRatherThanBPEL(i);
    qry = "/ns8:TmpInvStoc3Collection/ns8:TmpInvStoc3[" + i + "]/ns8:batchid";
    setVariableData("S2C_insert_InputVariable","TmpInvStoc3Collection",qry,value);
}

The code could be more efficient but it should do what you want.
