I am Moving my application Web-logic to Tomcat7

Question

The below code is working fine while the application is running in weblogic but in tomcat it is giving an error. The main problem is loading java:comp/env/jmx/runtime.

So please let me know what configuration I need to do to run the code in tomcat.

My Code:

    MBeanServer server = (MBeanServer)ctx.lookup("java:comp/env/jmx/runtime");
    // Get the Platform MBean Server
    ObjectName rs = new ObjectName("com.bea:Name=RuntimeService,Type=weblogic.management.mbeanservers.runtime.RuntimeServiceMBean");
    HashMap map = null;
    try
    {
        ObjectName domCfg = (ObjectName) server.getAttribute(rs,"DomainConfiguration");

        ObjectName[] jdbcSysResources =
        (ObjectName[]) server.getAttribute(domCfg, "JDBCSystemResources");

        map = new HashMap();
        for (int i=0 ; i<jdbcSysResources.length ; i++)
        {
            ObjectName jdbcResourceBean = (ObjectName) server.getAttribute(jdbcSysResources[i],"JDBCResource");

            ObjectName driverParamsBean =(ObjectName)server.getAttribute(jdbcResourceBean,"JDBCDriverParams");
            StringBuffer jdbcParams = new StringBuffer();
            ObjectName drvPropertiesBean = (ObjectName)server.getAttribute(driverParamsBean,"Properties");
            ObjectName[] drvProperties = (ObjectName[])server.getAttribute(drvPropertiesBean,"Properties");

            for(int j=0; j<drvProperties.length; j++)
            {
                String propName = (String)server.getAttribute(drvProperties[j],"Name");
                String propVal = (String)server.getAttribute(drvProperties[j],"Value");
                jdbcParams.append(propName).append("=").append(propVal).append(";");
            }
            String strTest = drvProperties.toString();

            ObjectName dsnParams =(ObjectName)server.getAttribute(jdbcResourceBean,"JDBCDataSourceParams"); 
            String[] dsnParamNames = (String[])server.getAttribute(dsnParams,"JNDINames");
            map.put(dsnParamNames[0].toString(),jdbcParams.toString());

Error in tomcat server:-

Tomcat doesn't come with a JNDI broker, unlike Weblogic. To make the code work as is, you'd need to add some JNDI provider.

I'd recommend using DI instead.

spring framework can do either (for example).

Here's an example

It is a legacy application. I cant use DI/Spring here. So please let me know how can I lookup all JNDI in tomcat. – Sudip Biswas Apr 23 '15 at 19:19
