How to load a jira core api class dynamically?

Hello Atlassian Team,

I am unmarshaling a json string element containing the following fully qualified class name:

com.atlassian.jira.workflow.function.issue.UpdateIssueStatusFunction

I am trying to obtain the Class object for this class using the following line of code

Class.forName("com.atlassian.jira.workflow.function.issue.UpdateIssueStatusFunction");

When I run this code, I am getting ClassNotFoundException. We then realized that the class was not getting loaded. In order to load the class, I had to run the following lines of code:

log.warn(String.valueOf(UpdateIssueStatusFunction.class));

Class.forName("com.atlassian.jira.workflow.function.issue.UpdateIssueStatusFunction");

This line loaded the class and then I was able to obtain the Class object that I needed.

Now coming to the question.

Could you please tell me how to load the class using a classLoader (or something similar) when I want to generalize the above line of code as following:

Class.forName(name); // name is a string which receives a value at runtime.

?

Hello Jobin,

Thank you for your solutions. I was able to figure out the class in JIRA core API that can dynamically load classes given the name of the class as a string. The following code was able to load the class that I needed dynamically.

ClassLoaderUtils.loadClass(name, <this-class-name>.class.getClassLoader());
