I've replaced the XML-block concerning the DeploymentManager with the
contents of jetty-deploy.xml and jetty-plus.xml and now I get Webapps
again. Hurray ;-)

But in the process I had to solve a problem where I'm not sure
if it's a PEBKAC or actually a bug in Jetty:

From the plus-xml:

  


  

  org.eclipse.jetty.plus.webapp.EnvConfiguration
  org.eclipse.jetty.plus.webapp.PlusConfiguration

  

  

I've used a different ID, hence the different reference at the beginning.
When I use that in my configuration I get a ClassCastException:

18:17:03.394+0200 [main] WARN   - unable to start HTTP-server with config file 
etc\admin.xml

I've spent most of the day finding the reason of the problem on my side but
the longer I looked the more it appears to me that XmlConfiguration chooses
the wrong method in Configurations. Instead of add(String[]) it seems to
try to call add(Configuration).

I've solved it by changing the configuration to call the method
XmlConfiguration is using anyway.

Re: [jetty-users] Webapps not loading after migration from 9.4 to 10.0

2022-04-27 Thread Joakim Erdfelt 
We maintain an example project of getting Embedded Jetty and JSP working
together at https://github.com/jetty-project/embedded-jetty-jsp

There's Jetty 9, Jetty 10, and Jetty 11 versions (see the branches with the
appropriate names).

Then there's also the general cookbook for Embedded Jetty that might help
you with specific topics as well.

https://github.com/jetty-project/embedded-jetty-cookbook

As for your specific concerns, you are likely not initializing the JSP
layer properly (see first link above to jsp examples), and/or are still
using older Configuration (class/object) techniques (see second link above
to cookbook examples).

[jetty-users] Webapps not loading after migration from 9.4 to 10.0

2022-04-27 Thread Lothar Kimmeringer 

Hi,

we have an appliation that uses Jetty in an embedded way since "the
begin of the world" (the configuration files have had a DTD-declaration
for Jetty 6... ;-)

I'm in the process of migrating from 9.4 to 10.0 and after going the
simple way by replacing the 9.4-jars with the jars of 10.0 the server
is starting up, programmatically added servlets are executed but
WARs loaded by the DeploymentManager lead to errors. I assume that
this simple approach is the reason. When starting up the following
messages show up:

Starting HTTP-server 'Main Server'

I'm wondering about the claim that JettyJspServlet and ELContextCleaner can't be
found. Both are in the classpath and can be found in the class starting the 
server
(checked with Class.forName).

What's the best way to embed Jetty 10? Resources online I've found only
cover Jetty up to version 9. The online documentation (Operation
and Programming don't mention Embedding at all - at least in the TOC).

Re: [jetty-users] webapps

2019-11-25 Thread Greg Wilkins 
The order is determined by the scanner mechanism which has a map iterator.
The order is thus indeterminate.

If an order is needed, then you probably need to replace the deployer with
a fixed XML that adds each of your webapps in order.

Hi,

is the a way to specify the order in which the applications in webapps 
should be started? Or is there a build in order which i don't know about?
