Knowing Java is absolutely recommended !
1 year for getting these 4 certifications is impossible due to the following information:
From TIBCO website:
BW611: TIBCO ActiveMatrix BusinessWorksTM 5.x Integration Boot Camp:
Recommended General Experience
One year Enterprise Application Integration development experience, have an understanding of concepts such as distributed computing, adapters, services and canonical data model, exposure to Message Oriented Middleware, Java and other relevant technologies: XML, XPath, HTTP, JMS, SOAP, JDBC and Web Services.
ARC701: Fundamentals of TIBCO Enterprise 3.0 Architecture
Product Specific Experience
Candidates should have at least: Two years experience designing message-based distributed systems using TIBCO products. One year of hands-on experience with TIBCO ActiveMatrix BusinessWorks, TIBCO ActiveMatrix Service Bus and TIBCO ActiveMatrix Service Grid. One year of active experience using TIBCO products delivering successful composite applications and services projects.
Apparently, these two certifications doesn't exists any more:
EMS11: Fundamentals of TIBCO Enterprise Message Service
BPM401: Developing Business Processes with TIBCO Business StudioTM 3.5.x
