Hi,
when i am trying to pass env reference as INOUT parameter to java method from esql ,I am getting below java reference error.
BIP3202E: (com.xxx.xx.test.getData, 1.1) : An error occurred when trying to resolve the Java class or method 'com.xxx.xx.test.DataUtil.getData' which is referred to by the routine 'getData'.
if i pass env reference as IN parameter it works fine for me. but as i want to store some data in env in java method,i have to pass as INOUT.
Please help me to understand what i am missing here . 
SET stat= getData("test",envRef);
ESQL Function
---------------------
CREATE FUNCTION getData(IN test CHARACTER,INOUT envRef REFERENCE)
RETURNS CHARACTER
LANGUAGE JAVA
EXTERNAL NAME "com.xxx.xx.test.DataUtil.getData";
--Java Method
public static String getData(String test,MbElement envRef){
try {
return "OK";
} catch (Exception mbExp) {
return mbExp.getMessage();
}
}
}
Thanks in advance!! |

Why do you need to pass the parameter as INOUT ? You are not changing the pointer. You are changing the tree structure beneath the pointer.
Just pass the parameter as IN and see what the change does to the structure...
