I'm glad to see that (a) Tomcat doesn't have a bug and (b) there is an
update to Tiles that works correctly with Tomcat. I suspect the
underlying problem was an edge-case conflict with Tomcat's new
"resources" implementation, which is based upon URLs instead of the
old-style "DirContext" which looked more like a standard filesystem
API. This change can make weird things happen if the library isn't
consistent about the way it loads resources.

Re: Strange JSP compilation issues in tomcat 7 and 8

2015-07-07 Thread paul
Hi Christopher,

I can confirm that in tomcat 8.0.23 the application does not work with or
without ##'s in the file name, however in tomcat 8.0.15 it works without
the hashes.

I compiled a list of my tests and the exceptions that occurred, they are
different in tomcat 7 and tomcat 8:

I have them in an excel spreadsheet if they are of any use to you but I
dont know if attachments are allowed on these emails?

I have managed to get this working now though thankfully and it was
actually down to something quite simple...

I deployed a standard JSP file and this compiled ok so I narrowed it down
to just being a Tiles issue.

My pom used to have version 3.0.3 defined and when I upgraded this to
3.0.5 the issues have gone away in both tomcat 7 and tomcat 8 using java 7
or java 8 and it also work without issue in tomcat 8.0.23.

If only I had tried that first!

Thanks to everyone who replied offering help.

Paul

 I am working on a spring\tiles application which I have been
 deploying to tomcat7 (7.0.32 and 7.0.53) and tomcat8 (8.2.0.23) and
 my war files are built with maven using jdk1.7.0_09.

 In my pom file I declare the final name using the ## syntax
 that I was told before on this mailing list would ensure that when
 deploying to tomcat that I would not get the version name as part of
 the context and so could just use the web app name in the url and in
 the past this has worked ok for me.

 ${finalName}##${project.version}



 So my war file build with a name like mywebapp##0.0.0.war, I
 deploy this with tomcat manager or manually and it deploys ok, no
 errors I can see on deployment.

 However when I try to access any pages I get jsp compilation
 issues, in both versions of tomcat 7 I get this error:

 org.springframework.web.util.NestedServletException: Request
 processing failed; nested exception is
 org.apache.tiles.request.render.CannotRenderException:

 If I deploy the war files without the ## in the name so just
 like mywebapp.war then they deploy and run fine in both versions of
 tomcat7 and tomcat8.

 Does anybody have any idea what could be the problem?



 I have in the past deployed war files with the ## in the web

 cause any issues.

Another thing that you can check is that you do not pack ECJ library or in
the Tomcat lib you do not have two versions for ECJ library.

I've seen problems with libraries that use URIs to load files instead
of using the ClassLoader. The problem is that the WAR filename
contains "#" which is an illegal character in a URL. Due to various
escaping, unescaping, re-escaping, etc. it's possible that a certain
combination can result in a file that can't be loaded due to the
illegal character issue.

Can you confirm that your web application otherwise works properly
without the "##" in the filename?

Re: Strange JSP compilation issues in tomcat 7 and 8

2015-07-06 Thread paul
I was really hoping that there would be something tomcat related in the
WEB-INF\lib folder but nothing, they are all marked as provided in the pom
file.

There was a mistake in my original post, in tomcat 8.0.23 my application
does not work with jdk's 1.7.0_09 or 1.8.0_11 so basically it doesnt work
at all in 8.023 with or without the ## in the war file name.

It seems like tomcat is just unable to compile jsp files in this version.

Is there anything else I can check or do? I have seen some people say they
edited the conf/web.xml for the jsp servlet entry, I tried setting the
params to 1.7 for compilerSourceVM and compilerTargetVM but this had no
effect.

I am pretty stuck as the tomcat page
http://tomcat.apache.org/whichversion.html seems to imply everything is
compatible??

I have seen similar errors on maven based projects, when the jsp api lib was 
put into WEB-INF/lib/. Check your libs in that location. Remove any servlet 
specific libs from there.

Strange JSP compilation issues in tomcat 7 and 8

2015-07-04 Thread paul
I am working on a spring\tiles application which I have been deploying to
tomcat7 (7.0.32 and 7.0.53) and tomcat8 (8.2.0.23) and my war files are
built with maven using jdk1.7.0_09.

In my pom file I declare the final name using the ## syntax that I was
told before on this mailing list would ensure that when deploying to
tomcat that I would not get the version name as part of the context and so
could just use the web app name in the url and in the past this has worked
ok for me.

${finalName}##${project.version}

So my war file build with a name like mywebapp##0.0.0.war, I deploy this
with tomcat manager or manually and it deploys ok, no errors I can see on
deployment.

However when I try to access any pages I get jsp compilation issues, in
both versions of tomcat 7 I get this error:

org.springframework.web.util.NestedServletException: Request processing
failed; nested exception is
org.apache.tiles.request.render.CannotRenderException: ServletException
including path '/WEB-INF/tiles/layout.jsp'.

org.apache.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: 1 in the generated java file
The type java.util.Map$Entry cannot be resolved. It is indirectly
referenced from required .class files

And when deploying to tomcat8 I get this error:

javax.servlet.ServletException: Could not resolve view with name
'base/dashboard/view' in servlet with name 'appServlet'

If I deploy the war files without the ## in the name so just like
mywebapp.war then they deploy and run fine in both versions of tomcat7 and
tomcat8.

Does anybody have any idea what could be the problem?

I have in the past deployed war files with the ## in the web app name
without any issues and whilst they didnt use Spring and Apache Tiles they
did use a lot of jsp's and this didnt cause any issues.

I should also point out that the web app with the problems contains all
the display\front end but the back end which has no jsps or tiles but is
still a spring web app but only provides rest apis for the web front end
to call does not have any issues with the ## in the war file name and I
have not had to change this wars name at all whilst doing this testing.

Its odd in that I can start tomcat with the ## and get an error, stop it,
clean down the work directory and then remove rhe ## from the war name and
restart tomcat and it works now.
