Handle Strings in UDF

[Former Member]

Hi Guys,

I have a UDF in my Mapping and in this function I don't know how to read String values out the Inbound Context.

When I write for example

public void HandleString(String[] var1, String[] var2, ResultList result, ResultList result2, ResultList result3, Container container) throws StreamTransformationException{

int pos = var1[0].indexOf("");* there occurs an exception: Exception:java.lang.ArrayIndexOutOfBoundsException: 0

Can you please tell me what I did wrong?.

Thanks already.

Best Regards

Martin

Hello,

Instead of creating your UDF inside the definitions tab in message mapping, try creating it in the functions tab.

Hope this helps,

Hi Mark,

sorry for not telling this information. That is what I am doing.... I write my coding in the functions-tab.

Hello,

int pos = var1[0].indexOf("");* 

Maybe the reason for the error is that you don't have any blank values in var1, that is why when you pass it to an array, it is giving an out of bound exception because pos has a value of -1.

Hope this helps,

Mark

I look for "*" in my String, not for Blank.... my mistake. Sorry.

var1 is one Inbound parameter and in the queue is only one value. But don't know how to read this value.

Converting to Integer doesn't work

Try the below code:

String s = var1[0].toString();

int pos = s.indexOf('*');

Hi Rahul,

thanks for your Reply. But the error still exists.

String s = var1[0].toString();

int pos = s.indexOf('*');

int pos1 = 0;

String sub2 = null;

int length = s.length()-1;

String zspeich1 = null;

String zspeich2 = null;

while(pos != (length-1)){

zspeich1 = s.substring(0, pos);

result.addValue(zspeich1);

pos1 = s.indexOf("*", pos+1);

if (pos1>0)

zspeich2 = s.substring(pos+1, pos1);

result2.addValue(zspeich2);

pos = pos1;

if (pos == (length-1)){

zspeich2 = s.substring(length, length+1);

result2.addValue(zspeich2);

}

}

Here my whole coding. everywhere I use a String method I inserted the "s".

try this

if (var1.length > 0){

//put in here all your code

}

else return "";

Hello Martin,

String sub2 = null;
int length = s.length()-1;
String zspeich1 = null;
String zspeich2 = null;

Can you try using

String sub2 = "";
String zspeich1 = "";
String zspeich2 = "";

Hope this helps,

Mark

Hi Martin, This is incorrect format: >> Public void HandleString(String ] var1, String[ var2, ResultList result, ResultList result2, ResultList result3, Container container) throws StreamTransformationException The Square brackets are incorrect to be present in the statement this way... Is this correct in your PI function library? Regards, Nipun

Hi,

You have to convert input String to integer.

Use the following code:

int pos = Integer.parseInt(var1);

or

int pos = Integer.valueOf(var1);
