JavaURLContextFactory ERROR when execute REST service

[Ramesh Udari1]

Hi,

We have a coomman code which actually connects external database by using datasoure concept. When we call this code from JIRA customized Services (configured in jira adminstrotor), this code executes without any issues and connect to database, but where as when we call same code from REST service which gives ------Root exception is java.lang.ClassNotFoundException: org.apache.naming.java.javaURLContextFactory. error and not able to connect database.

Both services (Rest and jira service) are implemented as plugin type 2 plugins.

Below is the JNDI look up code:

public static void setupDataSource(String dataSourceName) {
		Context envCtx;
		try {
			
			envCtx = (Context) new InitialContext().lookup("java:comp/env");
			
			// Look up our data source
			if(dataSourceName != null && dataSourceName.equalsIgnoreCase(getProperty("database"))) {
				
dsForDW = (DataSource) envCtx.lookup("jdbc/"+dataSourceName);
				
			} 
			  
		} catch (NamingException e) {
			logger.error("Problem Occured in getting Datasource",e);
		}
	}

As @Radu Dumitriuexplained

There are some things that you should be aware. From REST annotated classes, it will give you error (Classloader on the generated proxy is wrong)

To get do the lookup use

ClassLoader origCL = Thread.currentThread().getContextClassLoader();
try {
Thread.currentThread().setContextClassLoader(ComponentManager.class.getClassLoader());
//::TODO:: do lookup here
} finally {
Thread.currentThread().setContextClassLoader(origCL);
}

Hi Boris,

Thanks for your response, where should we add above code ?

In the setupDataSource method before doing the lookup. Probably you should have separate method for loading the datasource from REST
