Copy Project start error

Copying a new project today made a low-level mistake and recorded it as a warning:

Copied the project, copied the configuration file, modified the service name, launched Tomcat, the error is as follows:

Severe: creation of the naming context failed:  javax.naming.operationnotsupportedexception: context is read  Onlyjavax.naming.namenotfoundexception: name [comp/env/testservice] is not bound  in this Context. Unable to find [comp].at  Org.apache.naming.NamingContext.lookup (namingcontext.java:819) At org.apache.naming.namingcontext.lookup ( namingcontext.java:167) At org.apache.naming.selectorcontext.lookup (selectorcontext.java:156) at  Javax.naming.InitialContext.lookup (initialcontext.java:411) at com.jerehnet.util.dbutil.dbhelper.< Clinit> (dbhelper.java:55) At com.jerehnet.manage.applicationlistener.getcategorymapgift ( applicationlistener.java:82) at com.jerehnet.manage.applicationlistener.contextinitialized ( applicationlistener.java:29) At org.apache.catalina.core.standardcontext.listenerstart ( standardcontext.java:4973) At org.apache.catalina.

The survey only found that the configuration file has errors:

Original:

<service name= "Test" >    <connector port= "1111"      Maxhttpheadersize= "8192"                 maxthreads= "2048"  minsparethreads= " maxsparethreads=" 475 "                enablelookups= "false"  redirectport= "8443"  acceptcount= "              "  connectiontimeout= "20000"  disableuploadtimeout= "true"   uriencoding= "Utf-8"/>     <engine name= "test"  defaulthost= "localhost" >         <realm classname= "Org.apache.catalina.realm.UserDatabaseRealm"  resourcename= " Userdatabase "/>        
 Copy the NEW: 
 
<service name= "Test2" >    <connector port= "1111"      maxhttpheadersize= "8192"                 maxthreads= "2048"  minsparethreads= " maxsparethreads=" 475 "                enablelookups= "false"  redirectPort= " 8443 " acceptcount="                 connectiontimeout= "20000"  disableuploadtimeout= "true"   uriencoding= "Utf-8"/>     <engine name= "test"  defaulthost= "localhost" >         <realm classname= "Org.apache.catalina.realm.UserDatabaseRealm"   Resourcename= "userdatabase"/>        
The error is to modify only the server name
<service name= "Test2" >
Without modification
Engine Name
After adjusting the problem as follows, if you are also this error, you can try to see if this is the problem!
<service name= "Test2" > <connector port= "1111" maxhttpheadersize= "8192" maxthreads= "2048" MinS               parethreads= "maxsparethreads=" 475 "enablelookups=" false "redirectport=" 8443 "acceptcount=" 800 " connectiontimeout= "20000" disableuploadtimeout= "true" uriencoding= "Utf-8"/> <engine name= "Test2" DefaultHo st= "localhost" >
