[jboss-user] [Snowdrop] - Re: TransactionManager and UserTransaction

Andreas Panagiotidis [https://community.jboss.org/people/apanag] created the discussion "Re: TransactionManager and UserTransaction" To view the discussion, visit: https://community.jboss.org/message/746024#746024 -------------------------------------------------------------- It's exactly like this, I  had the same problem with Spring and JBoss 4.2. Exception Caused by: org.springframework.transaction.TransactionSystemException: JTA TransactionManager is not available at JNDI location [java:/TransactionManager]; nested exception is org.springframework.jndi.TypeMismatchNamingException: *Object* of type [class org.jboss.tm.*TxManager*] available at JNDI location [java:/TransactionManager] *is not assignable* to [*javax.transaction.TransactionManager*] My application had added in the EAR its own JTA library, thus this one was used instead of the jta that comes from JBoss. I use maven, so excluding the JTA artifacts in my pom solved the problem. <dependency>     <groupId>org.hibernate</groupId>     <artifactId>hibernate-validator</artifactId>     <exclusions>      ...          <exclusion>              <groupId>javax.transaction</groupId>              <artifactId>jta</artifactId>           </exclusion>     </exclusions> </dependency> <dependency>     <groupId>org.quartz-scheduler</groupId>     <artifactId>quartz</artifactId>     <version>1.8.4</version>     <exclusions>          <exclusion>              <artifactId>slf4j-api</artifactId>              <groupId>org.slf4j</groupId>          </exclusion>          <exclusion>               <groupId>javax.transaction</groupId>               <artifactId>jta</artifactId>                 </exclusion>          </exclusions> </dependency> -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/746024#746024] Start a new discussion in Snowdrop at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
