This happens when trying to add a mapping.

Thoughts?

mmelby,

Can you please post all the information we request in the Posting Guidelines thread at the top of this forum? That will give us some context so that we can determine if this is an installation issue, a configuration problem, or a bug.

Thanks,
Brian.

Sorry, here is some more information.

The error occurs when viewing the hibernate.cfg.xml with the MyEclipse Hibernate Config Editor. When I select to open the file using this editor I am presented with a popup warning stating "Unsupported Content Type in Editor. To associate file extension with a supported content type, please see Content Type Preferences Page". I click ok and proceed. From the editor I select the "Add..." button under the mappings heading. When selecting this button I get two Exceptions in error log.

Thank you for any help.

mmelby,

The unsupported content type issue is really odd. What is the file name of your configuration file?

Also, is it a valid configuration file? Can you paste the first few lines of your configuration up until the <hibernate-configuration> starting tag here?
Have you added Hibernate capabilites to the project containing the configuration file?

Best,
Brian.

Hi Brian,

The file name is hibernate.cfg.xml. It should be vaild as it was created using the wizard to add hibernate capabilities. Here it is..


<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<!-- Generated by MyEclipse Hibernate Tools. -->
<hibernate-configuration>

Thanks.

mmelby,
If that is the *entire* file, thta is not complete. Did you type that out or copy-paste the entire thing?

Also I just helped a user over a period of a week that was having a similar problem with our HTML/JSP designer and it all turned out to be a problem with XML Buddy interfering with our editors not letting it load the content.

Do you have XML Buddy installed?
