WildFly Error while running application --java.lang.ClassNotFoundException: javax.naming.InitialContext

I'm using JSPs and WildFly 9.0.2.Final with the following conditions:

  1. A JSP file (test.jsp) is accessing Test.java file.

  2. Test.java file is part of testclient.jar and has been deployed as a module.

  3. test.jsp file is part of Test.ear and has been deployed successfully but following error occurred while accessing the Test.java file from test.jsp:

These are the contents of test.jsp file present in test.ear:

<%@page import="com.testmodule.pojo.Test"%>
<% try {
    System.out.println(" Going to call getDbConnection method of 'Test' class. This 'Test' class shall be "
        +" part of testclient.jar. testclient.jar shall be deployed as a module --- module add --name=testclient --resources=~/Downloads/lib/test/testclient.jar");
    System.out.println("This file test.jsp shall be present in test.ear...'jboss-deployment-structure.xml' shall be present in "
        +" in META-INF directory of test.ear with entry as -- <dependencies><module name=\"testclient\" export=\"true\" /> </dependencies>");
    new Test().getDbConnection();
} catch(Exception e){
    e.printStackTrace();
} %>

And these are the contents of Test.java present in testclient.jar:

package com.testmodule.pojo;

import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;

public class Test { 
    public void getDbConnection(){
        try{
            Context context = new InitialContext(new Properties());
        } catch(Exception e){}
    }
}
Solution

  • I think you need to add a dependency to the module: javax.api.

    Try to add

    <dependencies>
    <module name="javax.api"/>
</dependencies>

    to your module.xml
