Business Objects Java

Question

I need help extracting all the file names within a folder in Business Objects. With the code I have now I can get the name of a single file within a folder. I want to get all the file names in that folder. The variable temp is where I enter the name of the file that I want. The variable doc is where the file name is retrieved, and the variable reportname is where I store doc to write to an external spreadsheet.

public class variable {

    private static String expressionEx;
    private static String nameEx;
    private static String nameXE[] = new String[11];
    private static String expressionXE[] = new String[11];
    private static String query;
    public static String reportName;
    private static String reportPath;

Answer 1

If Temp is going to hold the name of a unique folder, then you can use this code. Replace the String query = line with:

IInfoObjects oParents = infoStore.query("select si_id from ci_infoobjects where si_kind = 'folder' and si_name = '" + temp + "'");
if(oParents.size()==0)
    return; // folder name not found

IInfoObject oParent = (IInfoObject)oParents.get(0);

String query = "select SI_NAME, SI_ID from CI_INFOOBJECTS "
        + "where SI_KIND = 'Webi' and si_parentid = " + oParent.getID();

I don't see in the code where you're populating the temp, username, or password variables, but I assume you just left that out of the listing intentionally. Obviously they will need to be defined.

Couple of other things I noticed in your code:

• You are purging the query in each report, but not saving the report afterwards.
• You are storing the report's SQL in an instance variable named query, but you also have a local variable named query in the variable constructor. This could very likely cause a conflict if you need the SQL value for something.
• You have an "empty catch" for SDKException. SDKExceptions can happen for all kinds of reasons, and as it is you will not know why the program failed. You should at least be printing out the exception, or just let it bubble up.
