Assuming your project directory is something like this C:\dev\projects\YourProjectName\__source
for example (it can be anything).

You shouldn't get an exception for TLD if you have lib and tld folders under WEB-INF like
this:

C:\dev\projects\YourProjectName\__source\WEB-INF\lib\    
jstl.jar (assuming you are using JSTL1.1 or higher)

C:\dev\projects\YourProjectName\__source\WEB-INF\tld\ 
(If you are using JSTL version lower than 1.1 then you need to explicitly place the tld files
here, otherwise there's no need to specify tld files here)

C:\dev\projects\YourProjectName\__source\WEB-INF\classes\
(Your compiled class files)

And hence your project root folder is where all source files are present:
C:/dev/projects/YourProjectName/__source

<Context docBase="C:/dev/projects/YourProjectName/__source"
         privileged="false" antiResourceLocking="false" antiJARLocking="false" crossContext="false"
reloadable="true" cachingAllowed="false">
</Context>

Note that this kind of setup is ideal for the development environment only.

You will no longer need to deploy or undeploy your application as long as you are working
on the development environment. 
Manually remove projects and WAR files that are under C:\dev\apache-tomcat-5.5.12\webapps\
 (just one time)
The only time you'll need to use ANT in development environment is when you want to compile
your Java files.

Deploying and undeploying should only be reserved when deploying to staging or production
environments. 

For example you can have something like for staging and production:
C:\dev\projects\YourProjectName\__source\   - This is also your project root folder

C:\dev\projects\YourProjectName\01build\  (Optional intermediate build files with JSPC precompile,
extra white space compression etc)

C:\dev\projects\YourProjectName\02build\ (Preview of files that will be packaged into the
WAR file)

C:\dev\projects\YourProjectName\dist\YourProjectName.war (to be uploaded to qa, staging or
production environments)

Be careful not to undeploy your projects source folder, there's no need.
~~~~~~~~~~~~~~~

If you were originally deploying to Tomcat's webapps folder to see changes in your JSPs etc,
you'll need to modify your ANT script to not do this anymore.

Hi !

Yes, it does work !! This plus my discovery of yesterday (Eclipse's working
sets) et voila ! My productivity increases. But just three things to add :



2006/12/2, Rashmi Rubdi <dev_subscriptions@yahoo.com>:

Then inside the above context XML file define your context for example:
<Context docBase="C:/dev/projects/YourProjectName/__source"
        privileged="false" antiResourceLocking="false"
antiJARLocking="false" crossContext="false" reloadable="true"
cachingAllowed="false">
</Context>


For me, I must give the project root to the docBase attribute. Otherwise, it
throws exceptions saying my taglibs are not found. Maybe it's because my
sourceFolder is in a sub-folder of my project root while my libFolder is
under /WEB-INF/libs (WEB-INF itself being under the root).


***
Now re-start Tomcat and make some changes to your JSP file and you can
simply refresh your browser to see the changes, no need to perform ANT or
other deploy to webapps to see your changes.
***

Yes, all is fine, except that if I undeploy my webapp for a reason or
another, the webapp.xml gets erased by Tomcat. Not a real concern !





***
The simplest thing to do, if all you're after is to be able to see
changes to JSPs quickly, without any compiling, redeploying, etc, is
just to put the JSP files directly in a folder in $TOMCAT_HOME/
webapps, and edit them there.

That's not so easy when you use Eclipse. Because of its workspaces and
all...

Anyway, thank you two from a new Tomcat / JSP user !

It's even simpler to simply keep your source files in your original project
