@ejb.finder signature="java.util.Collection find(java.lang.String a)"
    query="select object(a) from customer a where a.customerId like like '" + a + "%'"

@jboss.finder-query name="find" 
    query="select object(a) from customer a where a.customerId like '" + a + "%'"

是错误的写法，EJBQL不支持这样写法。写成like ?1就可以了。之后在调用方法的时候人为加一个%

@ejb.bean primkey-field="customerId"

@ejb.pk class="java.lang.String"
