ArrayList - java.lang.ArrayIndexOutOfBoundsException

[takahashi]

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!
