What is the relationship between isomorphicDir(javascript variable) and servlet mapping url(web.xml)

[justpdh]

i using SmartClient v11 and i will use SmartClient v12

i change isomorphicDir for test

<script>var isomorphicDir="./isomorphic-12/";</script>

and I met an error.




I want to keep the existing folder(isomorphic v11 directory)

and

I want to create a new directoryisomorphic v12 directory)

and

I want to use servelet mapping url '/isomorphic/IDACall'


I hope your response

Hi justpdh,

I'd not change the isomorphicDir at all.
You are not running the application twice at the same time in 11 and 12, correct? This would not work, because you'd have v11 and v12 versions of many basic JAR files.

Then just keep a copy of that old directory the old war file. Would that solve your use case?

Or you could deploy old and new as two separate applications under separate URLs in your Tomcat / Application server.

Dear Blama

Then just keep a copy of that old directory the old war file. Would that solve your use case?
>> yes. I solved already with maven build

In your reply I got what I wanted.

so,
i changed all servlet mappings of web.xml. /isomorphic/ --> /isomorphic-12/

It works!


There is one more question..

Can I use all modules of SmartClient when I change the address to '/isomorphic-12/'?


Thank you.

Hi,

I don't know this, but don't think there is a problem. Only important thing is not to have duplicate JARs (e.g. isomorphic_core.jar) in one project.
Also, JARs in use and JS code should/must match.

Still, I don't get why you want to change this.

Dear Blama

This is for rollback when a compatibility issue occurs

Is it the wrong way?

Hi,

assuming nothing in the DB changes, you can just keep your old war file and roll it out if necessary, can't you?

Also, you could offer that old war as 2nd application under a different URL. Then you have a fallback, that is already live (of course, the user would have to enter a different URL, but you could also redirect from the default URL in that emergency case).
