How to send Oracle rowid to servlet? | Problem with national characters.

Question

There is same possibility how to send rowid to servlet?
I have now definition like this:
<af:image source="/imageservlet?Par1=#{bindings.Col1.inputValue}"/>
But If column contents national characters, servlet methods obtained changed these characters.
My idea is to use not primary key for row, but use oracle rowid. It is simply possible?
Use something like this:
<af:image source="/imageservlet?Rowid=#{bindings.Rowid}"/
Or Do you have ideas how to solve problem with national characters ?
Thanks

Hi,
Although your workaround works.
I think this is a simple encoding problem.
I simply need to make sure all parameters and pages are encoded with a char set which contains the national characters you mentioned.
This is a bit dependent on the exact technology your using, but most can be done via the web.xml:
  <jsp-config>
      <jsp-property-group>
          <url-pattern>*.jsp</url-pattern>
          <page-encoding>UTF-8</page-encoding>
      </jsp-property-group>
  </jsp-config>     This forces all JSP pages to be encoded in UTF-8
Adding the following parameter sometimes helps as well, although I think this one is a bit dated:
You said your using a servlet so your servlet needs a similar block for its pattern
  <context-param>
    <param-name>PARAMETER_ENCODING</param-name>
    <param-value>UTF-8</param-value>
  </context-param>If you want to be 100% sure the encoding is set right make sure thepages contain:
<%@ page contentType="text/html;charset=utf-8"%>Or depending on your view technology the syntax can be a bit different
