Message Mapping activation error-Source code has syntax errors in UDF

[Former Member]

Hi all,

I wrote a small UDF for sum of 2 numbers:

import

udf.*

public String getsum(String a, String b, Container container) throws StreamTransformationException{

int c = Integer.parseInt(a);

int d = Integer.parseInt(b);

int e = packageDemo.getSum(c,d);

return e+"";}

In imported archives, i imported pack.jar

In D:\udf , I have packageDemo.java, packageDemo.class, aii_map_api.jar, pack.jar(has the other 3)

packageDemo.java :-

package udf;

public class packageDemo{

public static int getSum(int a,int b)

{

int c= a+b;

return c;

}}

Did i miss anything?? Icant activate message mapping for 2 errors:-

1.package udf does not exist

2.Function getsum, Line 3:

cannot find symbol symbol : variable packageDemo location: class com.sap.xi.tf._xml_mm_int e = packageDemo.getSum(c,d); ^Note: /usr/sap/P7R/DVEBMGS00/j2ee/cluster/server0/./temp/classpath_resolver/Mapd4214d3099dc11dd9470001d090e4bbe/source/com/sap/xi/tf/_xml_mm_.java uses or overrides a deprecated API.Note: Recompile with -Xlint:deprecation for details.Note: /usr/sap/P7R/DVEBMGS00/j2ee/cluster/server0/./temp/classpath_resolver/Mapd4214d3099dc11dd9470001d090e4bbe/source/com/sap/xi/tf/_xml_mm_.java uses unchecked or unsafe operations.Note: Recompile with -Xlint:unchecked for details.2 errors

Hi ,

Think the error is coming because the content in imported archive is not being taken into message mapping at all...so package, class, method ..nothing is identified.

Can anyone suggest the solution..

Thanks,

Hi,

I think before using the "return" statement you have to convert the integer into string. You are using "return c" where c is a integer.

Why and how are u using StreamTransformationException. Try to run the scenario removing this. And import only the class file as a jar file.

Hi Prateek,

Iam using PI 7.1..In that StreamTransformationException comes default and i also tried importing only the class file as a jar file..but in vain..same error..

Hi,

why do you need the getSum method?

>int e = c + d;
