Recommending ESAPI?


(I just posted this on the SC-L mailing list and ESAPI users list)

Following the recent thread on Java 6 security and ESAPI, I just would like to ask the following clarifications: 

1) For an existing web application currently using a MVC framework (like Spring or Struts) are we today (9th Jan 2009) officially recommending that this web application development team adds OWASP's ESAPI.jar to the list of 'external' APIs (i.e. libs) they use, support and maintain?

2) When adopting the OWASP ESAPI's J2EE implementation, is ESAPI.jar ALL they need to add? or are there other dependencies (i.e. jars) that also need to be added, supported and maintained? (for example on the 'Dependencies' section of the ESAPI Java EE page (i.e. Tab) it seems to imply that there are other *.jars needed)

3) Where can I find detailed information about each of the 9 Security Controls that ESAPI.jar currently supports: 1) Authentication, 2) Access control, 3) Input validation, 4) Output encoding/escaping, 5) Cryptography, 6) Error handling and logging, 7) Communication security, 8) HTTP security and 9) Security configuration? (I took this list of controls from the Introduction to ESAPI pdf)

4) When adopting EASPI.jar, are we recommending that the developers should adopt or retrofit their existing code on the areas affected by those 9 Security Controls? (i.e. code related to: Authentication, Access control, Input validation, Output encoding/escaping, Cryptography, Error handling and logging, Communication security, HTTP security and Security configuration) 

5) Should we recommend the adoption of ALL 9 Security Controls? or are there some controls that are not ready today (9 Jan 2009) for production environments and should not be recommended? (for example is the 'Authentication' control as mature as the 'Error handling and logging' control?)

6) Are there commercial (i.e. paid) support services available for the companies who want to add ESAPI.jar to they application?

7) What is the version of ESAPI.jar that we should recommend? the version 1.4 (which looks like a stable release) or the version 2.0 rc4 (which looks like it is a Release Candidate)

8) Where can I find the documentation of where and how ESAPI should be used? More importantly, where can I find the information of how it CAN NOT or SHOULD NOT be used (i.e. the cases where even when the EASPI.jar are used, the application is still vulnerable)

9) if there list of companies that have currently added ESAPI.jar to their applications and have deployed it? (i.e. real world usage of EASPI)

10) Has the recommended ESAPI.jar (1.4 or 2.0 rc4) been through a security review? and if so where can I read its report?

11) when Jim says "... you can build a new secure app without an ESAPI. But libs like OWASP ESAPI will get you there faster and cheaper....",  do we have peer-reviewed data that suports this claim? 

12) Is there a roadmap or how-to for companies that wish to adopt ESAPI.jar on an a) new application or b) existing real-world application'?

13) What about the current implementations of ESAPI for the other languages. Are we also recommending their use?

14) If a development team decides to use (for example) Spring and ESAPI together in their (new or existing) application, what are the recommended 'parts' from each of those APIs (Spring and EASPI) that the developers should be using? (for example: a) use Encoding from ESAPI, b) use Authentication from Spring, c) use Authorization from ESAPI, d) use Error Handling from Spring, e) use Logging from ESAPI, etc...)

Thanks
