Tomcat doesn't refreshes and still gives me an old error again and
again
Hi Expert,
I am facing this problem - that Tomcat - 9.0.24 doesn't refreshes and it will give ma an error, even after I commented out a line. But, after several cleaning - using Tomcat Directory clean, right-click on the project in Eclipse and do a run maven force update and project built, it will still give me an error that point out to a commented out line.
Can I know if the above indicate a corrupted Tomcat instance or what should I do in order not to have the above problem crop up again and again?
Eclipse
Maven Java EE, JSP, JSTL
OS : Windows10
Tomcat : 9.0.24
Thanks & regards,
Karen

Yes. Eclipse will export a dynamic web project to a WAR file.

I still use Eclipse. I connect to the Tomcat process using remote
debugging and debug my way through Tomcat and/or the web application as
necessary.

Hi Mark,
This is completely new to me. When you said use the "Export" are you referrring to the Export inside Eclipse?
How do you debug without Eclipse then ?
Apart from those times where I've managed to export to the wrong Tomcat
instance (entirely my own fault) I've never had an issue.
As an added bonus it makes it easy to debug into the Tomcat code when I
need to but I accept that that is something a Tomcat developer is going
to want to do rather more frequently than someone developing a web app.

Personally, I gave up on using Tomcat and Eclipse in this way a long
time ago. It is a little more work but I run a completely separate
Tomcat instance and then use the "Export...", "WAR file" option to
deploy the latest version of my webapp to the external Tomcat instance
and then let Tomcat's auto-deploy take care of things.
Apart from those times where I've managed to export to the wrong Tomcat

Re: Tomcat doesn't refreshes and still gives me an old error again

Hi Karen, I´m not sure if it's still valuable to you. But make sure to double click on your tomcat server in eclipse, and check the value od server location field. Should be something like [eclipse workspace location]\.metadata\.plugins\org.eclipse.wst.server.core\tmpX where X is any number starting from 0. Which is basically the path to tomcat work directory people were talking about. From here navigate to wtpwebapps folder. You will see folders which correspond to your web apps[projects in eclipse]. You basically will find the copy content of your WebContent folder from Eclipse project. Eclipse usually copies files from your |Webcontent folder to here right after you make changes and save your project changes. Sometimes it doesn't do this and you end up with a situation like yours. Then you have to manualy copy the specific file you have problems with. I've had this happen to me a few times and the first time it happend it was so frustrating. Hope this helps you

Or just navigate Windows Explorer to the "work" directory and press

Hi Chris,
Just to clarify, so instead of doing the clean, I will have to to to this place - C:\Program Files\Apache\apache-tomcat-9.0.24\webapps\webappname and delete weappname ?
I happened to read this https://stackoverflow.com/questions/763693/where-is-the-work-directory-located-for-a-tomcat-instance-running-in-eclipse
I checked the location when I right-clicked the Tomcat instance, it says meta data, so should I delete the metadata one ? My Tomcat configuration is take control of Tomcat installation.
Kindly advise. And thanks for your help.

Not at all. You are deleting the "work" directory for the application.
Only do this when Tomcat is not running, otherwise it will probably
get very upset. You probably don't need to do this. I was just helping
you translate *NIX-speak into Windows-speak.

You've reached the limit of my knowledge when it comes to Eclipse. I
mostly use Eclipse as a text editor with auto-complete and syntax
checking. I do builds and deployments separately.

Hi Chris,
Just to clarify, so instead of doing the clean, I will have to to to this place - C:\Program Files\Apache\apache-tomcat-9.0.24\webapps\webappname and delete weappname ?
I happened to read this https://stackoverflow.com/questions/763693/where-is-the-work-directory-located-for-a-tomcat-instance-running-in-eclipse
I checked the location when I right-clicked the Tomcat instance, it says meta data, so should I delete the metadata one ? My Tomcat configuration is take control of Tomcat installation.

Do you have a tomcat/work directory? ISTR sometimes having to
rm -rf /var/cache/tomcat/work/Catalina/localhost/{webappname}
Could you let me know how to do it Windows 10 way? Sorry for the trouble cos basically most of my stuff is still using Windows 10....
although it was never obvious why I sometimes had to, but generally
didn't.

Eclipse works the way it works, but what you can use is
https://marketplace.eclipse.org/content/eclipse-tomcat-plugin which is
basically an update of the mighty
http://www.eclipsetotale.com/tomcatPlugin.html
I use a blank dynamic web project, with a standard plugin setup, ie default
output folder ../../WEB-INF/classes. I then fudge the WEB-INF/lib folder
by using a maven task to copy the jars from my war build process. The
devloader is good but I could not find a way to play nicely with maven.
You then use the debugging as part of the plugin.
