Problem in sending Soap message with long Japanese strings

Hey All,

I have a client built using VC++ running on Windows which sends Soap messages to a web service deployed on Tomcat that uses Axis.

The client is being localized in Japanese as well.
Here comes the problem:
When user enters a lot of doube-byte Japanese characters in the client UI then error occurs while sending the soap request. The error occurs when Finished() is called. This problem does not occur in following cases:
- if user enters lesser number of characters as input
- in English version.

I am using InitWithComposer() method of SoapSerializer30 to compose the soap since the message may contain attachmetns too. DimeComposer30 is used in this method.

Also, I noticed if I use Init() method instead of InitWithComposer. This problem does not occur

Can somebody tell me where the problem is? The code is also listed below for reference.
Soap toolkit 3.0 is being used and UTF-8 encoding is used in XML.

The error returned is given below.
