mvn tomcat:deploy "Cannot invoke Tomcat manager"

[cnordenfelt]

Following the tutorial I get to the step where to deploy the first time. When executing mvn tomcat:deploy I get the error "Cannot invoke Tomcat manager", which origins form org.apache.maven.plugin.MojoExecutionException: Cannot invoke Tomcat manager. My guess it has to do with the role and user I specified in tomcat-users.xml (which I have done according to the tutorial).

Now, the thing is I have several Tomcat instances and, me being a maven novice, I can't figure out which one is being used by mvn tomcat:deploy. I suspect I did not change the correct tomcat-users.xml (the one I changed was in ../SpringSource tc Server v6.0-config/, I also tried the one included with sts 2.3).

Hi, Carl

On my installation, I only keep one tomcat running and let it use 8080 port. I also have following settings in my [Tomcat directory]/conf/tomcat-users.xml

<tomcat-users>
<role rolename="manager"/>
<user username="admin" password="" roles="manager"/>
</tomcat-users>

Hope it helps.

BTW, you may want to redownload the roo addon zip from springsurf.org and reinstall it.

1) Download http://www.springsurf.org/downloads/...-roo-addon.zip

2) Startup Roo and remove existing surf addon

>> addon uninstall *surf*.zip

3) Reinstall surf addon using the zip file you just download

>> addon install file:/[Path-to-your-zip-file]

Thanks!

This was a really stupid mistake by me. I assumed that mvn tomcat:deploy started tomcat as well. It works fine if I manually start tomcat before i deploy.

I have a similar problem. I have successfully managed to deploy the webapp the first time, but once I've made changes and tried to deploy again, it says...

I tried, mvn tomcat:redeploy, which seemed to be successful, but resulted in

HTTP Status 404 - /community/

type Status report

message /community/

description The requested resource (/community/) is not available.
Apache Tomcat/6.0.20

For the second time, you might want to try

mvn tomcat:redeploy

Yong

[ajmillar]

Tried that, that results in the 404 message. See bottom of my last post.

And for some reason, it resets the changes back to the main template.

For example. I made changes as per the tutorial to

C:\sprinf-surf-sandbox\community\src\main\webapp\WEB-INF\webscripts\footer\footer.get.js

To give a different footer. I deployed it initially using mvn tomcat:deploy and it deployed successfully to the tomcat server.

However when going back into the same file, it has reverted back to the original file.

[ajmillar]

Getting the following message in the tomcat logs when trying mvn tomcat:redeploy

[TomcatAspectJWeavingClassLoader@1ca2b38] warning javax.* types are not being wo

Are you using a clean installation of Tomcat 6? Can you try to clean up tomcat temp, work directory and remove the deployed webapp (both war file and expanded directory) from webapps directory?

Yong

[ajmillar]

Yes, it was a clean version of tomcat.

Cleaning things up helps, but I don't want to have to do that everytime I want to deploy changes.

On the flip side, doing it via STS seems to work nicely.
