and need some basic difference in udf function which differe depend on cache parameter that is value,context and queue..

Thanks and Regards

Hi,

Please provide your UDF code as it is in your mapping program.

Thanks,

//write your code here

String a;

char[] chr = a.toCharArray();

String result = "";

for(int i = 0; i < chr.length ; i++) {

if(Character.isLetter(chr<i>)){

result = result + Character.toString(chr<i>);

}

}

//System.out.println(res);

return result.

the purpose of this function is to eliminate special charecters from the string to get a clean string.....

modify the code

if(Character.isLetter(chr <i> )){

result = result + Character.toString(chr [<i>] );

change chr[<i>] instead of chr

[prateek · Accepted solution]

Use this

//write your code here

char[] chr = a.toCharArray();

String result = "";

for(int i = 0; i < chr.length ; i++) {

if(Character.isLetter(chr<i>)){

result = result + Character.toString(chr<i>);

}

}

//System.out.println(res);

return result;

function myudf(String a, Container container)

{

char[] chr = a.toCharArray();

String result = "";

for(int i = 0; i < chr.length ; i++) {

if(Character.isLetter(chr<i>))

result = result + Character.toString(chr<i>);

}

return result;

}

modify the code as chr<i> instead of chr

i met this kind of error before

in my case, the disk is full no free space

if yours is not like this, you can try to restart the XI.

Line n: Identifier expected

*******************************

for eg->

public void tryIt(int a, b URL c)

This type of error will give rise to error messages of the form:

Line n: Identifier expected

bcos type is missing for b.

Simple UDF

**************

Value: expects the individual/multiple values as input parameters

return single output.

Advanced UDF

*****************

2 modes

**********

Context: expects the context as input parameter

Queue: expects the entire queue as input parameter for function.

returns ResultList contains list of values.

no return statement.

Hi Vijay,

/usr/sap/XD1/DVEBMGS00/j2ee/cluster/server0/./temp/classpath_resolver/Map795d7670202511dd9cc700144fad690b/source/com/sap/xi/tf/_MM_ClaimPaid_XI_SAP_.java:1580: <identifier> expected

Please provide the code, so that we can understand where it is expecting identifier.

need some basic difference in udf function which differe depend on cache parameter that is value,context and queue..

Value: expects the individual/multiple values as input parameters

Context: expects the context as input parameter

Queue: expects the entire queue as input parameter for function.

please refer below links to understand what is Context and Queue:
