Symlinks to index JSP files.
Hi all,
I'm having some trouble with tomcat and symbolic links. I am working with
OSX and I use a local instance of Tomcat to do some testing before
deploying my site elsewhere.
What I want to do: I'd like to create a small script which will stop
tomcat, clear out old deployment folders, rebuild my project, copy the
resulting WAR file to the webapps folder, restart tomcat, wait for
deployment to finish, and finally replace a JSP file with a symbolic link
to the corresponding file that is in my workspace.
Why I want to do this: I'd like to be able to quickly rebuild and redeploy
my WAR and also edit my JSP files and see those changes by simply
refreshing the already-open page.
My problem: I have all of the above steps working so far. However, as soon
as I swap out the real index.JSP with a link to the one in my workspace, I
can no longer load the page, I get a 404 error instead.
What I have tried: I have found questions like mine asked many times and
usually the solution is to hunt down a "context.xml" file and add a tag
into that file, 'allowLinking="true"'. I have tried to add this tag into
"<tomcat home>/libexec/conf/context.xml", "<tomcat
home>/libexec/conf/Catalina/localhost/context.xml" (created this one) and
also "<tomcat home>/libexec/webapps/appname/META-INF/context.xml". After
multiple restarts, none of those seem to change any functionality that I
can see.
By trial and error, I have eventually found that if I follow these steps, I
can get the link to work for a little while...
Deploy the WAR
Load the page (It works)
Move index_bs.jsp to index_bs.jsp.bak (in the webapp directory)
Load the page (404, as expected)
Create a symbolic link from index_bs.jsp to index_bs.jsp.bak
Load the page (It works!)
Edit index_bs.jsp.bak, save
Load the page (404 again)
This seems very strange to me. Obviously I've reached a point where
symbolic linking works somewhat, but as soon as I edit the original file
(my main goal here) the link stops working as expected. Does anyone know
what I'm doing wrong here? I must be missing something...
Some information about my setup:
OSX 10.10.5
Tomcat 8.0.28 installed with my username running brew brew to
"/usr/local/Cellar/tomcat/8.0.28/"
"/usr/local/Cellar/tomcat/8.0.28/libexec/webapps/hue-web-1.0-SNAPSHOT.war"
deployed successfully to
"/usr/local/Cellar/tomcat/8.0.28/libexec/webapps/hue-web-1.0-SNAPSHOT/"
Target file is
"/Users/uid/mygithub/hue-stuff/hue-web/src/main/webapp/index_bs.jsp"

There are lots of folks who prefer IntelliJ, and many who feel that
Eclipse is a steaming pile of garbage compared to IntelliJ. So, my
guess is that this is possible in IJ -- you just need to figure out
how it works.
This list might not be the best place to ask, unfortunately.

Thanks Mark,
Regretfully, my favorite IDE right now is IntelliJ (I use the free one) but
it seems pretty obvious that it's not the right choice for developing this
kind of application, as it doesn't have any explicit support for this kind
of development at all. I might just have to buckle down and stat using
netbeans or eclipse and convince others to as well.
I know how to write scripts and create complicated build/run actions in
IntelliJ, but things definitely take on the order of seconds when I would
prefer they were instant. I will take a look at Takari and see if it can
help me.

I use Maven exclusively (migrated from Ant about 2 years ago). I've
never had the update problem with NetBeans and a NetBeans-controlled
Tomcat.
For Eclipse, I think there used to be issues. I run Mars.1 (just to
make sure that my pom.xml changes play nicely with Eclipe), and just
tried a small project.
Changes to index.jsp are reflected after a browser refresh.
Changes to CSS are reflected after a browser refresh.
My Eclipse setup for Tomcat uses the defaults, so if you take over a
locally installed Tomcat (rather than running out of
workspace/.metadata), your mileage may vary.
For NetBeans, I have compile-on-save turned on. This means that when I
save a Java file, only that file gets recompiled and added to
target/artifactId/WEB-INF/classes. Tomcat detects this and reloads the
web application automatically.
I don't know if this happens in Eclipse or not. I suppose that I could
test.
If you need / want incremental builds with Maven, you should check out
the Takari Maven Lifecycle plugin
(https://github.com/takari/takari-lifecycle). I haven't yet, but there
are lots of features that look promising (including incremental builds
for resource changes).
. . . . just my two cents

This is one of my big problems with Maven: it doesn't seem to really
be geared towards /development/. I'm sure it's great for end-to-end
builds, but for a simple "update my local deployment with that
2-character change I just did" doesn't seem to be on the menu.

For me, ant is integrated into my IDE. When I want to publish changes
to my locally-running dev environment, I just click a button and it's
done in a few ms. Tomcat reloads the resource and I'm good to go.

Re: Symlinks to index JSP files.
Posted by gmc filter <gm...@gmail.com>.
Chris, I am specifically trying to avoid rebuilding the project each time I
make small changes in jsp/html/whatever files, if that is what you are
suggesting. Now that you mention this, I doubt any maven plugin can achieve
what I'm trying to do either.
That did give me an idea though. I suppose I could write a script which
simply overwrites the deployed file with a copy from my workspace... I
would have to run this script each time I want to review my changes, which
is disappointing, but I guess it will work for now.

If Maven doesn't know how to copy one file from one place to another,
I'm still comfortable with my decision to completely ignore its
existence as a build tool.
With ant, it's as simple as (paraphrasing):
<copy toDir="${deploy.dir}">
<fileset dir="${jsp.source.dir}" includes="**/*.jsp" />
</copy>

Christopher,
I am currently using Maven to build my project and compile it into a WAR
file.
Does Maven have some plugin that can help me achieve what I am trying to do?

If you need an IDE-independent build process (which I highly recommend),
consider something like Apache ant (similar to UNIX "make" but way
better for the Java world) or even Maven, if you don't mind the overhead.
Using symlinks with Tomcat is sometimes problematic, though I can't
explain why it's actually failing for your specific case... I would have
expected that to work.

Yes, usage of IDEs can be controversial in teams. I cannot help with the
symlink issue, I just have the alternative approach to use an IDE to
support that JSP editing workflow.

Christoph,
I have a little experience with the way eclipse does this and I have gotten
it to work nicely, but to be honest I would like to keep my solution IDE
independent. There is little to no consensus among my peers about which IDE
is preferable and if I can provide a solution that will work for everyone,
that would be best.

e.g. eclipse provides good support for such a workflow. You would not need
symlinks then...
