Error while installing SAP JCO connector in Eclipse

Hi All,

I’m getting the following error while installing SAP JCO connector in Eclipse IDE 3.5.2.

Installation Procedure:

1. Download the Eclipse.
2. Install the import wizard for the JCO plug-in connectors (from  http://rcer.sf.net/update-site).
3. Importing the SAP Java connector by specifying the JCO libraries from the SAP market place (sapjco3-NTintel-3.0.10.zip).
4. Install the SAP R/3 connector SDK (from http://rcer.sf.net/update-site ).

So I’m facing the issue in the last step #4 while installing the SAP R/3 connector SDK.

Error:

Cannot complete the install because one or more required items could not be found.

Software being installed: SAP R/3 Connector SDK 0.1.0.201104252054 (net.sf.rcer.sdk.feature.group 0.1.0.201104252054)

Missing requirement: SAP R/3 Connector SDK 0.1.0.201104252054 (net.sf.rcer.sdk.feature.group 0.1.0.201104252054) requires 'org.eclipse.xtext.ui 0.0.0' but it could not be found

I have attached the error screen shot.

Please help.
