Solution

1. Learning more 2. Troubleshooting 3. Collecting data

Getting background information on i18n/DBCS
To understand how Java™ supports different languages, see the Java Internationalization description.

Troubleshooting these problems can be focused into two broad areas, Character Output and Character Input:
  • Character Output problems are associated with JavaServer Pages (JSP) that cannot display characters that are either hard coded into the body of a JSP or HTML page, or are pulled from some datasource. An example: The Euro symbol doesn't show up in a JSP on Solaris, or Korean characters show as question marks. These problems are handled initially by creating a simple testcase.

  • Character Input issues are almost always more complex and challenging to solve than Output problems. This type of problem can involve POST values/Request headers, JDBC drivers as well as Database settings and configuration. Test cases are of little to no use since the problem is a complex interaction within the specific environment. For this class of problems, a servlet engine trace and reproduction of the problem is often the best (and only) place to start problem determination.

One type of problem can often be mistaken as a character output problem. When a JSP cannot display characters taken from a database. A testcase will often be inconclusive. This can indicate that the problem is with the data stored in the database. This can be confirmed by checking the data directly.
