Re: TransformerException: Java constructor replace matching JavaScript argument types is ambiguous

This is a tricky quirk of Javascript in Java. Since strOut is a Java object, var input = strOut.toString(); means that "input" is also a Java string, not a Javascript string. Javascript strings have a replace that takes a regex function (/regex/) as a parameter, however Java strings take two string parameters in the replaceAll method:

Code:

input = input.replaceAll("[^A-Za-z0-9\+\/\=]", "");

You might have to modify the regex a bit as I'm not sure that Javascript and Java share the same regex structure.

(Just a note - I used replaceAll vs replace. Replace is a valid function, but it only operates on characters, not strings. ReplaceAll will take a string that CAN be a regex. See: http://java.sun.com/j2se/1.5.0/docs/...ng/String.html for more info)

Re: TransformerException: Java constructor replace

Problem: Java, Javascript String replace
I am trying to replace all instances of ' with ''.

In the preprocessor, JavaScript replace with regular expression works fine.

However, when I try to do the same in Destinations tab, Database Writer,and Javascript, it doesn't like it. It says suggested constructor(char, char) etc - error mentioned in the thread (above).

If I try with value.toString().replaceAll("is", "are"), replaceAll is not recognized.
Error message below:

[2008-10-06 15:44:36,864] ERROR (org.mule.impl.DefaultComponentExceptionStrategy:9 5): Caught exception in Exception Strategy for: 505150d3-0b9f-4ef8-bc55-83cf0f25f5fa: org.mozilla.javascript.EcmaError: TypeError: Cannot find function replaceAll. (a1267cb7-8b1e-4447-b725-35a6c972d32a#1138)
org.mozilla.javascript.EcmaError: TypeError: Cannot find function replaceAll. (a1267cb7-8b1e-4447-b725-35a6c972d32a#1138

I can do simple replace, but that will replace only the first instance. I am confused as to which method Mirth is looking for. If I try replaceAll (java) it doesn't recognize the funtion. If i just do replace with regular expression (javascript), it insists on using java.lang.String.

I'd appreciate your help.

Thanks.

I'm in the same situation... Trying to replace single quotes (') with non-obstructive characters (´):

Code:

$('c16').replace(/\'/g, "´")

But getting this error:

Code:

ERROR MESSAGE:	Error writing to database: 
org.mozilla.javascript.EvaluatorException: The choice of Java constructor replace matching JavaScript argument types (function,string) is ambiguous; candidate constructors are: 
    class java.lang.String replace(char,char)
    class java.lang.String replace(java.lang.CharSequence,java.lang.CharSequence) (bf36fa83-590f-4365-929f-c222598fafab#168)

Just wanted to share. I had a the same issue and figured this out if you want to use the '.replace' the way you where trying too cast the java string into a javascript string:

instead of:

Code:

var input = strOut.toString();

use:

Code:

var input = new String(strOut);

The .toString() is primarily for e4x to take an XML node and print its value.

Hope this helps you or anyone in the future.

@peisima

We do replacement of all charaters like this:

We have an array with the characters to be replaced called repArray.

var myMessage = message.toString();

for ( i = 0; i < repArray.length; i++ ) {
var idx = myMessage.indexOf( repArray[i][0] );

while ( idx > -1 ) {
myMessage = myMessage.replace( repArray[i][0], repArray[i][1] );
idx = myMessage.indexOf( repArray[i][0] );
}

}

message = myMessage;

If you do a .toString() on an xml element it will return the value of the element. If the value is XML it will return the xml in string form
