WS test returns: null (row:-1, col:-1)

[Former Member]

Hi,

Lately I've been developing web service for SAP Portal. It supposed to return String[][], but instead it gives me a message:

An error has occurred. Maybe the request is not accepted by the server:

null (row:-1, col:-1)

Full Response:

XML structure looks just fine. (text formated for clarity)

Part of Java code that generates String[][] result:

(please notice comment)

String[][] result = new String[resultRows.size()][columnCount];
for (int r=0; r<resultRows.size(); r++) {
String[] tmp = (String[])resultRows.get(r);
for (int c=0; c<tmp.length; c++) {
  if (tmp[c]!=null) {
    result[r][c] = tmp[c]; // if instead of tmp[c] i put here null or String "whatever" - web service returns expected array
  } else {
    result[r][c] = "y";
  }
}

Strange, isn't it? I would appriciate any help.

Hello everyone,

I got this: it turned out one of Strings in tmp[] was built like this:

tmp[c] = "blah" + myChar + "blah".

myChar was not initialized and that was the problem.

Topic closed.
