    Seam with tomcat - more trouble than it's worth?

    nubknacker Apr 11, 2009 6:21 PM

      I have been trying to setup seam to run with tomcat all day long simply because it takes jboss as 10 minutes or so to startup on my computer (really crudd HDD). I finally managed to create a new project from within eclipse using jboss tools and I thought everything worked till I tried to hit the database.


      My configuration..


      persistence.xml:


      <?xml version="1.0" encoding="UTF-8"?>
<!-- Persistence deployment descriptor for dev profile -->
<persistence xmlns="http://java.sun.com/xml/ns/persistence" 
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" 
             version="1.0">
             
   <persistence-unit name="seamt1" transaction-type="RESOURCE_LOCAL">
      <provider>org.hibernate.ejb.HibernatePersistence</provider>
      <jta-data-source>java:comp/env/jdbc/TestDB</jta-data-source>
      <properties>
         <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>
         <property name="hibernate.hbm2ddl.auto" value="validate"/>
         <property name="hibernate.show_sql" value="true"/>
         <property name="hibernate.format_sql" value="true"/>
         <!--<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>-->
      </properties>
   </persistence-unit>
    
</persistence>


      I had to replace the jta-data-source to make it work with tomcat.


      My context.xml required for tomcat:



      <Context path="/seamtom" docBase="jboss-seam-jpa" debug="5"
     reloadable="true" crossContext="true">

     <Resource name="jdbc/TestDB" auth="Container"
          type="javax.sql.DataSource" maxActive="100" maxIdle="30"
          maxWait="10000" username="erc" password = "erc"
          driverClassName="com.mysql.jdbc.Driver"
          url="jdbc:mysql://localhost:3306/erc"/>
     
</Context>




      My components.xml:

      I read in a thread on these forums (can't remember the link) that the line


      <transaction:entity-transaction entity-manager="#{entityManager}"/>


      must be added manually to projects created using eclipse. This is where the problem starts. If I comment that line, the server even refuses to show me the default home.seam page, simply returns a redirect loop error. If I uncomment that line, the EntityManager in my entity beans is null.


      What am I doing wrong?


      P.S. Please be gentle. :)
