Hippo Hello World with JSP; File not found

[tora...@gmail.com]

I'm running through the Hippo CMS Hello World tutorial. The tutorial uses FreeMarker, but I'm unfamiliar with FreeMarker so I thought I would be able to just copy the example using jsp instead. After adding a "home.jsp" file to the webfiles under \bootstrap\webfiles\src\main\resources\site\jsp\home.jsp I've then created a template node, a page node, and added the page to the sitemap under root. When I try to view the site at localhost:8080/site/ I get a blank page followed by the following error in the command line: javax.servlet.ServletException: File [/jsp/home.jsp] not found.

I'm sure this is a stupidly simple issue but I'm new to Hippo and don't even know where to start.

Hi,

Probably the template is configured this way by default in that example:

/hst:hst/hst:configurations/myhippoproject/hst:templates
+ homepage [hst:template]
- hst:renderpath = "webfile:/freemarker/home/home.ftl"

Template path in webfiles (webfile: URIs) are actually template pages
stored in Hippo JCR Repository, not file system. Therefore, it (Hippo
webfiles) cannot support JSP pages. You can use only .ftl templates with
webfiles.

You can use jsp pages instead like the following:
- Create home.jsp and put in site/src/main/webapp/WEB-INF/jsp/home.jsp.
- And change the hst:renderpath property like this:

/hst:hst/hst:configurations/myhippoproject/hst:templates
+ homepage [hst:template]
- hst:renderpath = "jsp/home.jsp"

Then it will find the jsp template in the file system at
/WEB-INF/jsp/home.jsp instead.

HTH,

Woonsan

Thank you. So since webfiles can't automatically update jsp files I will have to rebuild and restart hippo every time I make a change to them? Is there a way to update a file without rebuilding everything? That process takes a good couple minutes on my system and I won't be able to develop efficiently if I have to do that every time I change a single character in a file.

That is why webfiles are so handy. But you can achieve the same with jsps, see [1] for how to set up your project in Eclipse in such a way that you don't have to rebuild and restart so often. Another way is to use a tool like JRebel that achieves the same. This is a licensed tool though.

Thank you for the reply. I've gone back through the developing with eclipse tutorial and have a Tomcat server running, and everything works alright until eclipse tries to publish the changes. I get a list of errors indicating a bunch of files that it's trying to delete to rewrite and it "Could not delete":

Publishing failed with multiple errors

If I may ask for help one last time that'd be great!

Hi,

I recon we should document this more explicitly in [1], but when using web files, only FreeMarker templates are supported. If you want to use JSP, you'll have to store the templates under the site.war's WEB-INF folder, and re-deploy if you want to change your templates.

cheers

I apologize if this ends up getting posted twice. I'm working my way through the Hippo CMS Hello World tutorial. The tutorial uses FreeMarker but I'm unfamiliar with that so I'm trying to copy it using JSP instead. 

I've added a home.jsp file to the webfiles under \bootstrap\webfiles\src\main\resources\site\jsp\home.jsp. I then created a template node pointing to webfile:/jsp/home.jsp, created a page node pointing to the template, and then created a node called root to the sitemap pointing to the page.

After saving the changes I then try to view the site, but receive a blank page and the following error in the command line: javax.servlet.ServletException: File [/jsp/home.jsp] not found

I'm sure there is a stupidly simple solution, but being new to Hippo I don't even know where to begin looking. Thanks for any help!

Or use JRebel or Springloaded to reload the templates withoud doing a deployment.

Or use Eclipse with Tomcat as described on:
