Dear Sir,
When I tried to write Excel file using XLS template, there are some warning
messages with collections in the console as the followings though I was able
to see the expected Excel output. Because of huge amount of warning message
with collection value retrieval, the application log file size are
unexpectedly big as we have to write excel file for thousands of records.
Please provide us the advice how we can achieve to avoid these warning
messages. Thanks in advance. The followings are the warning messages.

The followings are sample object models, test case and jxls syntax.
public class User {
private String username;
private List<PhoneNumber> phoneNumbers;
public List<PhoneNumber> getPhoneNumbers() {
return phoneNumbers;
}
}
public class PhoneNumber {
public String ext;
public String value;
}
*JXLS syntax*
<jx:forEach items="${memberList}" var="member">
${member.getPhoneNumbers().get(0).value}
</jx:forEach>
Thanks in advance.
Best regards,
may
