I have downloaded the TIBCO Business Studio from the TIBCO official website . After Installing the application, when i opened the start menu, there were two options
1.Studio for analysts
2.Studio for designers
I opened the 2nd option i.e. studio for designers,and then i choosed the new->BPM for developers.
A interface was opened , but i found that the palette panel was not having the components like JDBC,JAVA,MAIL,etc.., that are usually found in the TIBCO designer.
