    ArrayList -  java.lang.ArrayIndexOutOfBoundsException

    mie takahashi Newbie

      Hi again...

      I posted error about String[][] a couple of weeks ago, and thank you for processing about this issue.

      This time I am trying to send/receive the ueser defined class with ArrayList variable, and getting the following error:


      12:03:21,093 ERROR [BeanPropertyTarget] Could not convert [Ltest.webservice.Subject; to bean field 'subjectArrayList[0]', type [Ltest.webservice.Subject;

      My JSE is:
      public interface StudentJSE extends Remote{
       Student updateStudent(Student target) throws RemoteException;
       StudentArrayList updateStudentArrayList(StudentArrayList targetList) throws RemoteException;
      
      }
      


      Student class is:
      public class Student implements Serializable {
       Subject[] subjectList;
       String name;
       :
       appropriate setters and getters
      }
      


      StudentArrayList class is:
      public class StudentArrayList implements Serializable {
       List subjecArraytList = new ArrayList();
       String name;
      
       public String getName() {
       return name;
       }
      
       public void setName(String name) {
       this.name = name;
       }
      
       public Subject[] getSubjectArrayList() {
       return(Subject[])this.subjecArraytList.toArray(new Subject[this.subjecArraytList.size()]);
       }
      
       public void setSubjectArrayList(Subject[] subjecArraytList) {
       this.subjecArraytList.clear();
       for(int j=0; j>subjecArraytList.length; j++) {
       this.subjecArraytList.add(subjecArraytList[j]);
       }
       }
      
      }
      
      


      It works fine with Student class. I can get the expected result through
      UpdateStudent method.
      BUT not StudentArrayList class.... UpdateStudentArrayList method terminated with the ArrayIndexOutOfBoundsException.

      I found the bug about ArrayList which is JBWS-383(JBoss doesn't properly
      support JavaBeans with array-type properties).
      Is this bug caused the error I encountered??

      How to solve this problem?
      I will be appreciated any help!!

          Collections are not supported in JAXRPC. You should use arrays.

            Hi Thomas,

            Thank you for your reply.

            I tried the same web-service on AXIS, it woked OK.
            I thought it worked fine with the bean class which has
            setters( parameter:array) and getters(return type: array)
            even if its property is ArrayList(collection type).
            I understand it won't work if I use setters(parameter: ArrayList)
            and getters(return type: ArrayList)....

            In my case, I have the following bean class property:


            List subjecArraytList = new ArrayList();


            And, I have these setter and getter:

            public Subject[] getSubjectArrayList() {
            return(Subject[])this.subjecArraytList.toArray(new Subject[this.subjecArraytList.size()]);
            }

            public void setSubjectArrayList(Subject[] subjecArraytList) {
            this.subjecArraytList.clear();
            for(int j=0; j>subjecArraytList.length; j++) {
            this.subjecArraytList.add(subjecArraytList[j]);
            }
            }


            The only way I can run this service on JBoss is to change ArrayList to Arrays???

            I found the following sun tutorial site:

            http://doc.albanet.ro/java/j2eetutorial14/doc/JAXRPC2.html#wp82023

            It says "This release of JAX-RPC also supports several implementation classes of the java.util.Collection interface".
            It includes ArrayList as well.

            Any advise is greatly appreciated!
