[jetty-dev] upgrade help

Brian Cox

Hi All,

 

I recently joined a new group doing, for the first time in a long time, Java and I am working with jetty for the first time. My first task has been upgrading the project’s use of jetty 8.1.7 to something more current. I recently grabbed 9.4.4 and seem to be running into one issue after another.

 

So I am going to start with a seriously newbie question. I’ve been grabbing updated versions of related jar files (servlet-api, javax.servlet.jsp, etc) and I have run into NoClassFoundExceptions, IllegalStateExceptions, etc and then today have hit:

 

Problem accessing /jaguar/admin/. Reason:

 

    Server Error

Caused by:

 

javax.servlet.ServletException: org.apache.jasper.JasperException: PWC6033: Error in Javac compilation for JSP

 

PWC6199: Generated servlet error:

package javax.servlet does not exist

 

PWC6199: Generated servlet error:

package javax.servlet.http does not exist

 

...

 

when loading a page.

 

So I’m backing up, starting over to make sure I have the right versions of everything to pair up with jetty 9.4.4.

 

Is there someplace that documents which jars I need to have installed to work with jsp 2.3?

 

Thanks for your help and your patience!

Brian

First question ...

Are you doing an upgrade of a distribution?
or embedded-jetty?

In reply to this post by Brian Cox

Brian,

You should not have to grab updated versions of jars.  If you are doing embedded work , then just use maven and it will resolve dependencies for you or if you want a stand alone server then the jetty-home or jetty-distribution packages come with all the dependencies needed for a base server and the module system downloads compatible jars for any enabled features that needs more.

Note that 8 to 9 was a particularly big change in APIs and configuration, so there may be a bit of work updating an embedded application.     If you are not using maven or a distro, then I suggest removing all org.eclipse.jetty jars and the servlet API and replacing them with the jars from jetty-home.   Then work from there.

cheers

Re: [jetty-dev] upgrade help

Greg (and Joakim earlier),

 

This helped so much, thank you! I was headed down the wrong path with the jetty-all-…-uber.jar, but using the jetty-distribution package was what I should have been using. We are doing embedded work and after taking the cdi*.jar files out of the project and making a couple of tweaks, it looks like things are working much better.

 

Thank you guys for the support!

Brian

Re: [jetty-dev] upgrade help

Brian Cox

Great, I’ll check it out, thanks!

 

One more thing that I have run into. It seems similar to an old bug (https://bugs.eclipse.org/bugs/show_bug.cgi?id=459490) where error-page page tags are being duplicated.

 

In my WEB-INF/web.xml I have:

<error-page>

                              <error-code>404</error-code>

                               <location>/error.do</location>

</error-page>

 

This is not defined anywhere else, including the webdefaults.xml. In fact I have changed the <error-code> and <location> values in web.xml to make sure that what I am using in *only* defined in web.xml.

 

At runtime I get:

Caused by: java.lang.IllegalStateException: Duplicate error-page 404 at /error.do

         at org.eclipse.jetty.webapp.StandardDescriptorProcessor.visitErrorPage(StandardDescriptorProcessor.java:1146)

         ... 41 common frames omitted

 

The only thing I can think of is that web.xml is being read in twice? Is that a possibility? If so, would reading it the second time through overwrite what was read in the first time or would we get this error?

 

Thanks in advance for any help you can offer!

Brian

Did anyone happen to have any insight into these questions below?

 

Ø  The only thing I can think of is that web.xml is being read in twice? Is that a possibility? If so, would reading it the second time through overwrite what was read in the first time or would we get this error

 

I’ll be digging into this issue again today, I appreciate any information you guys might have!

Can't think why.

Any chance you can put together a test webapp that reproduces the problem?
