I've tried very hard to use this plugin since I didn't want to install WTP, but I couldn't get passed the following error, despite making sure that servlet-api.jar was added to project libraries containing the mentioned class:

java.lang.ClassNotFoundException: javax.servlet.ServletContainerInitializer

It doesn't seem to play very well with Maven projects as well. Is that a known limitation?

Has anyone actually got this to work using eclipse 4.7.1a? I've figured out that it is incompatible with Java9, but with Java8 I still can't get the project/context set up correctly and the devloader doesn't seem to work either.

I've now got launching of tomcat and debugging to work, however cannot use the GUI to edit project settings. I have to manually edit the context.xml and .tomcatplugin metadata files which requires some previous knowlege.

Hello Jérémy Fournier!

I had the same problem on Linux Mint 17 (based on Ubuntu 14.04) and java oracle version "1.8.0_144".

My Solution.

1) Download and unzip "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 8" (first link google in my case)

2) replace both files in the directory $JAVA_HOME/jre/lib/security

3) restart eclipse.

Good luck!

Hi,

I too faced similar issue when dragging and dropping the plugin into eclipse.

The alternative worked for me was:

1. Go to the source forge site (click on "?')

2. Download the version of the tomcat plugin

3. Unzip the file, there should be folders features and plugins

4. Put the files of the folders into their respective folders in the eclipse root directory

5. Restart eclispe.

 

Thanks.

Hi Markus,

Is it possible to launch the tomcat plugin using java code?

If yes, is there any documents that I can refer?

Thanks!

Hi,

I tried to install the plugin on Eclipse Neon (4.6.2). In eclipse.ini I specified vm Java(TM) SE Runtime Environment (build 1.8.0_31-b13) (/home/superx/tools/jdk1.8.0_31/jre/bin/java).
When trying to install the plugin I get the error.
Unable to read repository at http tomcatplugin.sf.net/update/plugins/net.sf.eclipse.tomcat_9.1.2.jar.
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
On the console I saw the following log
org.eclipse.m2e.logback.configuration: Initializing logback
openjdk version "1.8.0_111"
OpenJDK Runtime Environment (IcedTea 3.2.0) (suse-3.1-x86_64)
OpenJDK 64-Bit Server VM (build 25.111-b14, mixed mode)
OpenJdk is needed by my Suse Leap 42.2 installation for LibreOffice, so I can't easily deinstall it.
What can I do?
Thanks for your help

Hi Meikel,

unfortunately this seems to be an issue with the mirror network provided by Sourceforge. Currently it does not seem to be fixed in the near future. Therefore I can only suggest you to try and try again until it has worked. I have seen people getting a successful installation after 20 or more tries. Sorry for inconvenience.

No, noone has implemented a CLI to the tomcat plugin so far. I am not sure if there's a real need for it. If you like to investigate further on this you could post a ticket on sourceforge so we can discuss further there. You could also join us in our IRC channel on freenode: https://webchat.freenode.net/?channels=tomcatplugin
