i have configured datasource in apache software foundation\tomcat 5.5\conf as:

  <globalnamingresources>     <environment       name="simplevalue"       type="java.lang.integer"       value="30"/>     <resource       name="jdbc/paymentsdb"       type="javax.sql.datasource"       maxactive="20"       maxidle="10"       username="root"       maxwait="20000"       validationquery="select=1"       driverclassname="com.mysql.jdbc.driver"       password="root"       url="jdbc\:mysql\://devserver\:3306/payhub"/>     <resource       auth="container"       description="user database can updated , saved"       name="userdatabase"       type="org.apache.catalina.userdatabase"       factory="org.apache.catalina.users.memoryuserdatabasefactory"       pathname="conf/tomcat-users.xml"/>   </globalnamingresources> 

and added apache software foundation\tomcat 5.5\conf\ context.xml page , added webinf\web.xml

 <resource-ref>    <description>paymentsdatabase</description>    <res-ref-name>jdbc/paymentsdb</res-ref-name>    <res-type>javax.sql.datasource</res-type>    <res-auth>container</res-auth> </resource-ref> 

i using spring framework,hybernate+jpa . please let me know, problem be?

i not recommend putting in global config tomcat. there's no guarantee you'll have access it. better put in meta-inf/context.xml.

you didn't show spring config jndi data source. please include that.

nested exception javax.naming.namenotfoundexception: name java:comp not bound in context

shouldn't java:comp/env?
