I am working on a requirement where I want to query the data and want to do the object mapping for the retrieved result using Solrj. For this, I am referring to the official document at *https://lucene.apache.org/solr/guide/7_6/using-solrj.html#java-object-binding <https://lucene.apache.org/solr/guide/7_6/using-solrj.html#java-object-binding>.* I set-up the necessary class files and the collections. With the help of this document, I can create the documents in the Solr DB, but it is not working for fetching and mapping the fields to the Java POJO class. To do the mapping, I used @Field annotation. Details are as below: *1)* Solrj version: 7.6.0 *2)* The line of code which is not working: *List<Employee> employees = response.getBeans(Employee.class);* *3)* Exception stack trace: *Caused by: java.lang.IllegalArgumentException: Can not set java.lang.String field demo.apache.solr.vo.Employee.name <http://demo.apache.solr.vo.Employee.name> to java.util.ArrayList* * at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(Unknown Source)* * at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(Unknown Source)* * at sun.reflect.UnsafeObjectFieldAccessorImpl.set(Unknown Source)* * at java.lang.reflect.Field.set(Unknown Source)* *4)* Collection was created using *solr.cmd create -c employees -s 2 -rf 2* Please find the attached source code files. Also, I attached the stack trace file. Can you please help me on how to resolve them? Regards, Swapnil Katkar -- Hello, Regards, Swapnil Katkar
