I would like to create a GUI that allows a user to view 2 database tables and then drag and drop mappings - mapping the columns from database 1 to the columns in database 2. Does anyone know of an open source project that does something similar, or any relevant tutorials?

Thanks for that, the fourth link has just what I need.

Hi Does anyone know of any java code that can be used to perform a calculation on a string. e.g "(10*2)+3" - The code would return 23 as a double.

Thanks for any help

If I don't open a new window how would I get the servlet to redirect to the screen which has the button that the user has just clicked on?

<a href='/app/downloadReports.do?ctrl=publishedReportList&action=DownloadXml¶m=0' target='_blank' title='Download Report XML'>
<img vspace='0' align='absmiddle' border='0' src='images/auditlogicon/contract.gif'>
</a>

I am using the following code inside a Servlet to allow users to click on a button to download (open/save) an XML file - This works fine. However when the user clicks the download button a new browser window is opened. Is there anyway using Servlets to close this window? I thought about changing the content type then writing out some JavaScript to close the browser, however I don�t think this is possible.

Any help would be greatly appreciated

response.setContentType( "text/xml" );
response.setHeader( "Content Disposition", "attachment;filename=downloadXML.xml" );

//send the data
response.getOutputStream().println( xmlDataString );
response.getOutputStream().flush();
