Migration jboss to tomcat - javax.naming.NamingException

We are Migrating Struts 1.2 project from JDK 1.6 to 1.8 and application server jboss5.1 to tomcat 8.0. Database connection is working fine and initial pages are loading and populating some data. But when i do any action(Submit button)it throws an exception javax.naming.NamingException: Cannot create resource instance Same code was working in jboss 5.1 but getting an error in Tomcat 8.

But i am suspecting reason for the error is UserTransaction needs to be defined separately in the context.xml but not sure about it. Please let me know.

UserTransaction ut = (UserTransaction) myCntxt.lookup("java:comp/UserTransaction");

If UserTransaction needs to be defined , Please let me know how to configure in Tomcat server ?

Added database configuration in context.xml under META-INF/context.xml

<Resource name="jdbc/Test1" 
   auth="Container" 
   type="javax.sql.DataSource" 
   maxTotal="100" 
   maxIdle="30" 
   maxWaitMillis="10000" 
   username="xxxxx" 
   password="xxxxx" 
   driverClassName="oracle.jdbc.OracleDriver" 
   url="jdbc:oracle:thin:@xxxx:1527:xxxx" />

<Resource name="jdbc/Test2" 
   auth="Container" 
   type="javax.sql.DataSource" 
   maxTotal="100" 
   maxIdle="30" 
   maxWaitMillis="10000" 
   username="xxxxx" 
   password="xxxxx" 
   driverClassName="oracle.jdbc.OracleDriver" 
   url="jdbc:oracle:thin:@xxxx:1527:xxxx" />

Added data source reference in web.xml under {project}/WEB-INF/web.xml

<resource-ref>
   <description>Oracle Datasource</description>
   <res-ref-name>jdbc/Test1</res-ref-name>
   <res-type>javax.sql.DataSource</res-type>
   <res-auth>Container</res-auth>
</resource-ref>

<resource-ref>
   <description>Oracle Datasource</description>
   <res-ref-name>jdbc/Test2</res-ref-name>
   <res-type>javax.sql.DataSource</res-type>
   <res-auth>Container</res-auth>
</resource-ref>

Sample Code

public static void dbInit(String test1dataSourceReference,String test2dataSourceReference) throws Exception
    {

        Context ctx = new InitialContext();
            tds =(DataSource) ctx.lookup("java:comp/env/" + test1dataSourceReference);
            cds = (DataSource) ctx.lookup("java:comp/env/" + test2dataSourceReference);

    }

Solution

As the TomEE Comparison page indicates Tomcat does not have support for JTA (JSR 907):

You'll either need to remove the JTA code or consider another EE server like Wildfly as a simpler upgrade path.
