help me!

I will take a stab at the dark here, because it looks like a simple example of CMP. But in your weblogic-cmp-rdbms-jar.xml file try removing the quotation marks from this line:
<![CDATA["(= car_name $s_car_name)"]]>
make it
<![CDATA[(= car_name $s_car_name)]]>

Hi
  thanks for your reply,i have try it but failed.

  in my weblogic-cmp-rdbms-jar.xml file i remove the quotation marks from this line:
<![CDATA["(= car_name $s_car_name)"]]>
make it
<![CDATA[(= car_name $s_car_name)]]>
when i use command :
java weblogic.ejbc cartype.jar cartypeEJB.jar
i got exception:

Scanner exception: line(1), no viable alt for char: s
ERROR: Error from ejbc: weblogic.cmp.rdbms.finders.IllegalExpressionException:
While trying to process Finder
        Method Name: findByName
        Parameter Types: (java.lang.String)
        WebLogic Query: (= car_name $s_car_name)
        Finder Expressions: ()
Invalid Identifier in WLQL expression: _car_name

ERROR: ejbc found errors

In my java Client i call findAll() method exception still is:

java.rmi.RemoteException: ; nested exception is:
        weblogic.rmi.ServerError: A RemoteException occurred in the server metho
d
 - with nested exception:
[java.lang.NoSuchMethodError: weblogic.ejb.internal.EJBHomeImpl: method findMeth
odInfo(Ljava/lang/String;)Lweblogic/ejb/internal/MethodInfo; not found]

Any suggestion will be appreciated! thanks

Looks like there were two problems in one line:
make:
<![CDATA["(= car_name $s_car_name)"]]>
this:
<![CDATA[(= car_name $0)]]>

which means car_name = the first parameter.

rich

It's ok ,Thanks!
