Beginners needs help!

Hi and Welcome to the community :) First of all, a basic knowledge of all the technologies you mentioned is "good to have" but not a must to create Mashups with the WSO2 Mashup Server. If you can write basic Javascript, you know how to write Mashups using the WSO2 Mashup Server. You can find introductory to advanced tutorials at http://wso2.org/library/mashup Since you seem to be interested in Data Service Mashups, I think http://wso2.org/library/tutorials/exposing-legacy-data-services-using-wso2-mashup-server would be helpful. As far as Database connections are concerned, all you need is a type 4 JDBC driver to connect to your database of choice. For Postgre, one can be found at http://jdbc.postgresql.org/ . Just drop it in the /lib directory of your Mashup Server installation and you are good to go. Let us know how things progress. Cheers, Tyrell

Thank you, I manage to connect to postgresql using the Generic RDMS and postgresql jdbc type 4. Thank again for the reply

How to use postgresql database when creating a dataservice???? In a drop down list there are only 2 types (derby and mysql)... how can I select postgre???? Thanks in advance...

You can add it to the Data Service's XML declaration at the very beginning. There's a part where JDBC information is given. Tyrell
