CannotResolveClassException while trying to transform xml string into java object - mule

I am trying to develop a mule flow which takes a xml in the form of a string from a JMS queue and converts it into a POJO. I am using JAXB annotations to define the mappings between the xml and the class attributes. Below is the sample xml that is received on the JMS queue as a string.
<FCUBS_NOTIFICATION xmlns="http://fcubs.ofss.com/notify/NOTIF_UP_TRANSACTION">
<FCUBS_NOTIF_HEADER>
<MSGID>9132820000357947</MSGID>
</FCUBS_NOTIF_HEADER>
</FCUBS_NOTIFICATION>
My POJO class is as below:
package com.bean;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
#XmlRootElement(name="FCUBS_NOTIFICATION")
public class Notification {
private String MSGID;
public String getMSGID() {
return MSGID;
}
#XmlElement(name="MSGID")
public void setMSGID(String mSGID) {
MSGID = mSGID;
}
}
I have a jaxb.index file in the com.bean package consisting of only one bean
Notification
My mule flow config file is as below:

Thanks in advance.

The serialization/deserialization in the xml-to-object-transformer is done through XStream, so JAXB won't matter at that point.
You would need an alias:
<mulexml:xml-to-object-transformer returnClass="com.bean.Notification" doc:name="XML to Object">
<mulexml:alias name="FCUBS_NOTIFICATION" class="com.bean.Notification"/>
</mulexml:xml-to-object-transformer>

Add new line to custom Exception message in Anypoint Studio Mule

I am using Anypoint Studio 6.1 and Mule 3.8.1 and want to return an Exception message with the "\n" returned as a new line. I am trying to use System.getProperty("line.separator") but the "\n" still appear in the message as text and not a new line.
How can I get this to work?

Looks like you need to escape the newline character. Also, use single quotes (') instead of double quotes (") inside MEL expression.

Mule rounding issue with JSON to object transformer

I have a JSON to object transformer that follows the datamapper in a Mule 3.6 workflow and found that the JSON to object transformer removes trailing zero in decimal fields so 11.00 becomes 11.0.
How can I prevent the JSON to Object transformer from dropping the last decimal place if it is a zero and enforce 2 decimal places so it will return 11.00 as this is a requirement?
An example flow showing the problem:
<?xml version="1.0" encoding="UTF-8"?>

<logger level="INFO" doc:name="Logger"/>
</flow>
</mule>
The test.csv file looks like this:
DeptID,Dept,Staff
5LL/A,Human Resources,4.00
You could create your own custom function that rounds your data, that can be used by datamapper. First add a configuration on your flow, to extend the expression language.
<configuration doc:name="Configuration">
<expression-language autoResolveVariables="true">
<import name="dataformatter" class="com.utils.DataFormatter" />
<global-functions >
def (value, places) { return dataformatter.round(value, places) }
</global-functions>
</expression-language>
</configuration>
//package com.utils.DataFormatter
public static double round(double value, int places) {
if (places < 0) throw new IllegalArgumentException();
BigDecimal bd = new BigDecimal(value);
bd = bd.setScale(places, RoundingMode.HALF_UP);
return bd.doubleValue();
}
From that code you could directly call the function and round it properly.
Hope this helps.

Passing a Mule payload object to Drools rule

I'm tying to build a mule flow which get data from a db, builds an object and then fires a drools rule. My problem is initialFacts-ref="#[payload.MapObject]" cannot be resolved. On deployment I'm getting 'No bean named '#[payload.MapObject]' is defined' How can I get the payload object into the rule as a fact?

initialFacts-ref refers to an existing Spring bean so you can't use a MEL expression as you try to. It is used for loading initial facts so that's why it's static.
In your case, it seems you just want to process the current message in a rule, not provide an initial set of facts to the rules engine. In this case, there's nothing to do. The current message payload is passed to Drools so you can access it directly.

How do you validate outbound properties using MUnit XML?

I am setting some outbound properties in the message prior to sending the payload to a JMS queue, and I wanted to test that those properties are properly set in the message prior to sending it out to the JMS queue.
I thought about using an MUnit Spy before the JMS Outbound Endpoint, but the spy is only capable of validating the session properties, invocation properties, and the payload. Is there another way that I can achieve this using MUnit XML?
I created a mini mule project to illustrate the issue further. The code is provided below. Essentially it is just a flow that calls a sub-flow that sets outbound properties in a mule message, and the MUnit has a spy that asserts that the outbound properties are set in the mule message after the sub-flow is called. However, the MUnit Spy doesn't seem to have access to the mule outbound properties. I would like to know if there is another way around this at this time. I know that the docs specify that the spy is only capable of validating session and invocation properties, and the payload at this time. Any suggestion is welcome.

Don't use 'Spy' for this, it has some limitations. Take a look to the documentation:
https://docs.mulesoft.com/mule-user-guide/v/3.7/the-spy-message-processor#defining-spy-actions
You could simply add the asserts after the flow ref.

You need to add an alias in the mulexml:xml-to-object-transformer:
<mulexml:alias name="CUSTOMER" class="com.abc.dto.CUSTOMER" />
Also there's no reason to go all caps with the class name so rename your class and alias it:
