Hello,

I have exactly the same error.

I have integrated jbpm 5.4.0.Final in my application and started to run very simple process. As soon as I created a new Gateway (my first one). it gets impossible to me to deploy my war application.

I'musing 5.5.0.Final of drools-spring.

I have extracted drools-spring-1.7.0.xsd Schema Definition file so I can point to it yith xml code as followis:
<beans xmlns=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans"
       xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance http://www.w3.org/2001/XMLSchema-instance"
       xmlns:jbpm=" http://drools.org/schema/drools-spring http://drools.org/schema/drools-spring"
       xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans 
                            http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
                            http://drools.org/schema/drools-spring http://drools.org/schema/drools-spring 
*classpath:drools-spring-1.7.0.xsd*">    
    <!-- JPBM Entity Manager Factory -->
    <bean id="jbpmEMF" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="persistenceUnitName" value="org.jbpm.persistence.jta"/>
    </bean>

Still I get the exception, whever my unique process includes a Gateway:
DEBUG 351014[RMICallHandler-6](TypeConverterDelegate.java:226) - *No String constructor found on type [org.drools.builder.ResourceType]*
