Hi All,

Below is the JAVA code for Adapter Module which I wrote for setting target directory based on source directory information.  The requirement is to read the Folder name where the files are placed and as per that Folder name we need to set the target directo

There are many nice blogs to tell about how to use NWDS for creating modules so not putting that information. Only the code for the Adapter Module I feel will be helpful for PI consultants.

    Hi Ashutosh Upadhyay,

    First of all thanks for sharing. However, your idea is similar that the Amit Srivastava‘s blog Send File to Two Different Locations using Adapter Module. I know there are differences because your module let to send to six locations and Amit’s one two locations.

    Unfortunately, may be is not possible i miss one option to send to N different locations. I have one question for you, Could be possible to do moduleContext.getContextData(“dirpath*”); in order to can generate infinite possible path parameters?

    Regards.

      Hi Inaki,

      It was specific requirement which I achieved with this java code. However we can modify the code ( I still need to code it and test it) by passing a parameter in adapter module to decide how many directories we need to choose and for dirPath we can take an array. Let me check if that logic works well with Adapter Module and then I will confirm it.

    Hi I have not tried it but made this logic I hope this helps. We can take count or number of folders we want and then using the loops we can set the parameters equals to the n.

    So with below code you can take the approach like suppose 3 directories you want to handle then pass count as 3 and then you need to pass parameters as input0, input2, input3.

          int i=0;

        String count = moduleContext.getContextData(“count”);
        int iCount =Integer.parseInt(count);

            String[] input = new String[iCount];

            String[] inputParameters = new String[iCount];

            String str = “”;

        for (i=0;i<iCount;i++){
    str = String.valueOf(i);
    input[i]=”input”+str;
        }
        for (i=0;i<iCount;i++){
    inputParameters[i]=moduleContext.getContextData(input[i]);
        }
