XSQLRequest problem.

Question

Hi,
I'm having some problems with the XSQLRequest.process() method and would appreciate any help.
I have an .xsql file that excepts a parameter called moltid and returns the needed xml. When I call this page from a regular html form I get the correct xml document back.
The problem comes when I try to request this document in a java serlvet. I create the request and a Hashtable containing the moltid parameter to pass to the page, make the request to process and get back an xml document that appears as if the parameter was not passed to it. The following is a section of my code:
// get the moltid
moltid = request.getParameter("moltid");
// Construct the URL of the XSQL Page
URL pageUrl = new URL("http://129.43.26.68/xml/mt_xml.xsql");
// Construct a new XSQL Page request
XSQLRequest xsqlRequest = new XSQLRequest(pageUrl);
// create a hashtable to hold the moltid parameter
Hashtable xsqlParams = new Hashtable(1);
xsqlParams.put("moltid", moltid);
// make the request passing the parameter to the page
xsqlRequest.process(xsqlParams, out, out);
After making this request this is the document I get back:
<?xml version="1.0" ?>
- <target>
<moltid />
<cell-line-data />
</target>
Needless to say there should be data associated with <moltid> and <cell-line-data>. It seems as if the moltid parameter in the Hashtable is not getting passed to the .xsql page.
Can anybody help?
Thanks,
Chris.

What role is your additional servlet playing in this picture? Wouldn't you get the result your looking for by letting the XSQL Servlet handle the request directly?
What platform and exact JVM are you using?<HR></BLOCKQUOTE>
Platform is win2000. JVM is the jdk1.2.2 from Sun.
In trying to get this to work I've discovered that it really does seem to be something with passing the Hashtable containing the parameters. I got it to work if I create the URL to include the parameter such as in the following code:
// Construct the URL of the XSQL Page
URL pageUrl = new URL("http://129.43.26.68/xml/mt_xml.xsql?moltid=" + moltid);
// Construct a new XSQL Page request
XSQLRequest xsqlRequest = new XSQLRequest(pageUrl);
// make the request passing the parameter to the page
xsqlRequest.process();
It's when I try to use the Hashtable to pass the parameters as in my previous post that it doesn't seem to work.
I'm not quite certain I understand your question about the role of my servlet. My servlet asks for an XML doc thru the url and then will parse the data in the XML to manipulate it the way I need it displayed. The XSQL Servlet just passes the data back, correct? I'm sure I could do other things using XSL, etc., but I wanted to try certain things where I take the data from the XML and build various objects to use and display the data.
Again any help would be appreciated at understanding why I can't seem to use the Hashtable way.
Thanks,
Chris.
