Hi,

When I create a Tuckey rewrite rule for a servlet that is located under /app (for example /app/helloworld), the rewrite rule is not working.

But when I create another Tuckey rewrite rule for something outside /app, for example a file/image, the rewrite rule works.

I think there is a bug or something that prevents Tuckey rewrite rules to be applied to anything under /app.

I've created an example plugin which demonstrates this weird behavior.

You can find this plugin here: https://github.com/yasindilekci/com.dotcms.tuckey-servlet

Steps to reproduce:

1. Clone repo

2. Build the plugin with gradlew.jar bat (windows)

3. Upload to your dotCMS instance

Visit the page to check if the Hello World Servlet is registered - should be ok

http://demo.dotcms.com/app/helloworld

Now try to visit the Hello World Servlet via the Tuckey rewrite rule, this won't work!

Rule created with addRewriteRule() method

http://demo.dotcms.com/foo/bar/servlet-test

Rule created with NormalRule class, won't work either

http://demo.dotcms.com/foo/bar/2servlet-test

Now use Tuckey rewrite rule to forward to a file (image), this works...

http://demo.dotcms.com/foo/bar/image-forward

Can someone please check why this is happenings?

Thanks.

I think there is a servlet mapped to /app in the default dotCMS web.xml. You will probably need to remove that.

Hi Will,

But wouldn't that not be the Apache Felix servlet (that is bound to /app/*)?

The intention is to forward the request to a servlet that is added by the Dynamic Plugin.

With kind regards,

We would want this to be a forward to prevent an extra request for CSS/JS.

We have been able to use Tuckey rewrite rules to override servlets in the /app/ folder in all latest versions. 2.5.4, 3.5.1, 4.0.1.

There is likely something wrong with your plugin.

Keep in mind after the rewrite, the original URL won’t work anymore.

So if your servlet is registered at “/app/funstuff”, “/app/funstuff” won’t work after mapping it to “/funstuff”.

This has been an issue since about version 3.6, any rule with the to type of "forward" does not work.

github issue: https://github.com/dotCMS/core/issues/9665

For example one of our rules for our blog was:

addRewriteRule("^/blog/([A-Za-z0-9\\-]+)/?$", "/blog/post.htm?urlTitle=$1", "forward", "ContentStreamURLMap");

This is the workaround we were given:

NormalRule rule = new NormalRule();

rule.setName("ContentStreamURLMap");

rule.setFrom("^/blog/([A-Za-z0-9\\-]+)/?$");

SetAttribute cmsFilterUrlMapOverrideAttribute = new SetAttribute();

cmsFilterUrlMapOverrideAttribute.setName("CMS_FILTER_URLMAP_OVERRIDE");

cmsFilterUrlMapOverrideAttribute.setValue("/blog/post.htm?urlTitle=$1");

rule.addSetAttribute(cmsFilterUrlMapOverrideAttribute);

addRewriteRule(rule);

Which does the trick, but obviously, would like forwards to work properly instead of having to pass them through the CMS filter like this.

Good news is that in the upcoming version of dotCMS, Vanity URLs are going to become content and respect regex based rewrite rules. I can confirm that in the latest master this works:

All of ours are type “forward” and they all work in the versions listed. (We have nearly 2 dozen.)

We’ve never had any environments on 3.6 however, but I can confirm it works in 4.0.1.

So, the current limitation on forwarding via tuckey will only apply if you are forwarding to a dotCMS page - not an external path or a struts/spring/servlet path. If you are forwarding to page in dotCMS via tuckey, you will need to set the CMS_FILTER_URLMAP_OVERRIDE value as Chris is doing.

Oh, ok. I don’t think we have any “page” forwards. Mostly servlets.
