overloaded setter methods

["Anusuri, Vijay M" <vi...@bankofamerica.com>]

 
Hi,  
 
I have two overloaded setter methods in DTO: one with Long Wrapper
parameter and another with long primitive.   This has been working fine
for several months.  But it stopped working recently and complaining
that "The error happened while setting a property on the result object".
I know what is happening here . Now  IBatis is started using setter
method with primitive long parameter.  Earlier It used use Long Wrapper
setter method.  What is the reason for this behavior?
 
 

Setter methods in DTO

  /**
   * @param parentAnalysisId The parentAnalysisId to set.
   */
  public void setParentAnalysisId(Long parentAnalysisId) {
    this.parentAnalysisId = parentAnalysisId;
  }

 

  /**
   * @param parentAnalysisId The parentAnalysisId to set.
   */
  public void setParentAnalysisId(long parentAnalysisId) {
    this.parentAnalysisId = new Long(parentAnalysisId);
  }

 

 
Thanks,
Vijay

Overloaded setter methods is a violation of the JavaBeans specification.  I
recommend you don't do it.  I also recommend you upgrade to JDK 1.5 if
possible, which will avoid the need for this entirely.

Even if you don't upgrade, overloading for this reason is a bad idea
IMHO....Java sucks for not having autoboxing until now, but dealing with it
using ad-hoc polypmorphism is probably not the best idea.  Honestly I'd
recommend just picking either the primitives or the object wrappers and
using them consistently.
