FlatFileItemReader using FixedLengthTokenizer not working
Question
I m doing an example in SpringBatch using a FlatFileItemReader with FixedLengthTokenizer to read from text file and save to an xml file. I got an error :Bean property 'fixedLengthTokenizer' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter? (I will put the hole console log). thank you for any help . config file : spring-batch-context.xml:

in the config spring bach file : spring-batch-context.xml : I changed this :
<property name="fixedLengthTokenizer">
<bean class="org.springframework.batch.item.file.transform.FixedLengthTokenizer">
<property name="names" value="fisrtName,id, phone,lastName ,streetName,age,city, date_of_birth,quantity,sin ,code"></property>
<property name="columns" value="1-4,6-9,10-13,15-18,19-22,23-26,27-31,33-40,45-47,48-53,55-55"></property>
</bean>
</property>
to :
<property name="lineTokenizer">
<bean class="org.springframework.batch.item.file.transform.FixedLengthTokenizer">
<property name="names" value="fisrtName,id, phone,lastName ,streetName,age,city, date_of_birth,quantity,sin ,code"></property>
<property name="columns" value="1-4,6-9,10-13,15-18,19-22,23-26,27-31,33-40,45-47,48-53,55-55"></property>
</bean>
</property>
it's worked fine.
