[Solved]How to retrieve MRE user ID from a jsp page?

I'd like to automate some jobs that requires some jsp coding. Is there a way to retrieve the MRE user ID (&IBIMR_User in webfocus) in JSP?

I know I can pass it through a form or URL from a webfocus page, but that doesn't seem secure enough. Is there a server variable (Tomcat) that can do this?

Thanks.

If you have already logged into MRE or dashboard, there will be a cookie that will have it.

I tried the cookie way, found 3 cookies. But they are long string of numbers. Seems they've been encrypted.

Oh that was an old status. We started using 7.66 a while ago. Can you please elaborate?

There is a javascript library called ibicookie.js.

This exists in ibi_html/javaassist/ibi/html/js.

This should be able to decode the cookie and get the user.

ibicookie.js does not provide an API to decrypt the WF_COOKIE information. However, I have found the java API from here:

/ibi_html/javadoc/wfapi/ibi/webfoc/wfsecurity/WFCredentials.html#method_summary

It seems that's the way to go. Just need sometime to pickup the jsp syntax I've forgotten a while ago.

Sorry for leading you down the garden path. Seems I was remembering Maintains cookie encrypt/decrypt.

So, there's no JavaScript way of retrieving a value from the encrypted MRE cookie?

You have to write and compile a Java program?

I have a case open with Tech Support. They claim

quote:
IBIMR_user is one of the values in the MR cookie.
It is not really encrypted. It is encoded in base64 and there are functions you can call to decode it from Javascipt


Well, I tried several JavaScript functions found on the web and none of them decrypt the MR cookie string to something recognizable.

Francis, I opened a case back in 2012 too. But the kid answered my case was not aware that they had such a java library at all.

Anyway I abandoned the case after a few helpless calls. Then a few months later I found this code buried in some old reports:

-SET &UID=EDIT(GETUSER(USERID),'9999999$$$$$');

It worked for me. Hope this helps...

For the record: In JSP you would have to get the cookie value, decrypt it then tokenize it to get the MR user id.

dhagen, what about in an HTML file? It appears I cannot use JavaScript to decrypt the cookie value - I get different results from three different base 64 decryption functions...

bug, I can't use -SET &UID=EDIT(GETUSER(USERID),'9999999$$$$$'); - I have an HTML file, not a fex.

Francis, you may have to use xmlhttp functionality to call a fex and get the user from the HTML page. You could have it as part of the onload event of th page.

The decrypt is implemented in the web app, and cannot be extended to JS. You would have to do what Waz suggested.

Two problems:

1) The JS solution is what IBI Tech Support suggested I use Frowner
2) I don't want to add another fex to an HTML Composer web page - it performs poorly in our cluster environment - nine different fexes to populate controls seems to choke the cluster server Frowner

Francis,

IF IBI Tech Support suggests a JS solution and you can't get it to work, ask them to give you a working example.
