Problem with length attribute included for array elements

Hello Support Team,

 

My application need to handle the XML file reading generated from .NET as well as Java platform. The XML file is uniform for both the platforms.

 

I developed a java file for performing the reading and writing XML file using java. My java file is having 2 array elements. When I wrote the java object to XML file, I observed that "lenth" attribute is automatically included for the array elements. I am able to read this file correctly using java. But when I tried to read a ".NET" generated xml file using my same java program, I am getting "ArrayIndexOutOfBoundsException". When reviewed the code, found that "length" attribute is missing for array elements. When I explicitly added this attribute for the corresponding elements. the problem was solved. The same problem I also encountered when I deleted the "length" attribute from java generated xml file.

 

So can anybody help me out how to resolve this issue? I need to read the .NET generated XML file without making any explicit changes i.e. without adding "length" attribute for array elements.

 

Thanks in advance.

Regards,

Vijay

Hi,

 

Yes, you have a number of options. One is to remove the length attribute from within the Strategy, the other is to use a list instead of an array. This does not have a length= attribute. Note, without the length attribute you can not deserialize an array properly, it may seem like a usless attribute, but its used to deserialize complex object graphs where the array must exist before the object it references.
