Can't add server to a moved workspace

Question

I have this workspace downloaded off the web and I try running it on a tomcat server from a fresh installation of Eclipse Ganymede. This particular project came with its own workspace.

When I select Tomcat v6.0 I get a message

Cannot create a server using the selected type

Older tomcat versions are available, though.

I guess I have to recreate some configuration setting. The question is which one? This seems to be some odd error as creating a new dynamic web project lets me configure tomcat for both of them

Solution 1

I had a similar problem, but my solution is a little simpler. The problem was causesd by renaming the original folder that was referenced by the server definition.

Go to Window/Preferences/Server/Runtime Environments, remove the broken reference. Then, click 'Add' to create a new reference, select the appropriate tomcat version, click next and you'll see the incorrect path reference. Fix it. Move on.

Solution 2

I had this same problem on Ubuntu 8.10 with Ganymede and Tomcat6. This appears to be some sort of bug with Eclipse. If you try and create a server, and it barfs, you can't create another tomcat6 server. To correct this problem, do the following:

• close eclipse
• go to the {workspace-directory}/.metadata/.plugins/org.eclipse.core.runtime/.settings directory and remove a file called org.eclipse.wst.server.core.prefs.
• start eclipse
• add your tomcat6 server in the server tab

@id thanks for the solution but something is also hidden in org.eclipse.jst.server.tomcat.core.prefs

So in order to solve the problem

• close eclipse
• go to {workspace-directory}/.metadata/.plugins/org.eclipse.core.runtime/.settings
• remove the files org.eclipse.wst.server.core.prefs and org.eclipse.jst.server.tomcat.core.prefs

Tomcat 5.5

I order to be able to use the tomcat5.5 server you need to have a writeable catalina.policy file as mentioned in

• http://dev.eclipse.org/newslists/news.eclipse.webtools/msg16795.html (= add a READ and WRITE permissions to the files in directory "{$tomcat.home}/conf" (chmod -vR a+rw {$tomcat.home}/conf/*). To be more specific, on the file "catalina.policy". After that, the Tomcat server can be added in the Eclipse servers)
• (dead link) http://webui.sourcelabs.com/eclipse/issues/239179 and to have the tomcat5.5 stopped before entering eclipse and started afterwards.

Tomcat 6

In order to be able to use the tomcat6 server the proper solution is to have a user instance of the tomcat6 server as described in

• /usr/share/doc/tomcat6-common/RUNNING.txt.gz
• RUNNING.txt (on the WEB)

My configuration is Debian/Sid, Eclipse 3.4.1. Ganymede

Solution 4

i finally got mine to work with the default Ubuntu 8.10 tomcat. (the debug command-line on eclipse is a wonderful thing) First i had to make a couple of symbolic links and then change the permissions to a file. (you might want to think twice about changing the permissions depending on your configuration, but if eclipse can't read the file it throws and exception and the gui won't let you continue)

sudo ln -s /etc/tomcat6 /usr/share/tomcat6/conf
sudo ln -s  /etc/tomcat6/policy.d/03catalina.policy /usr/share/tomcat6/conf/catalina.policy
sudo chmod a+r /usr/share/tomcat6/conf/tomcat-users.xml

Solution 5

The error view really is key. There is a lot of detail in there -- if necessary, right-click on the entries and copy their contents into your favorite text editor. One problem that can come up, for instance, is that if you have a server configuration already in place, and one of the configuration XML files is unparseable, the server can't be added. This happened to me this evening -- my <Context> element had a linebreak in it, so it was <C(linebreak)ontext>. This prevented Eclipse from recreating the server configuration.

this question truly saved me a lot of hazzle. (WoT - can't wait).

Try assigning the group tomcat7 to your user's groups as explained here stackoverflow.com/a/15505124/334569

in my case i had to delete org.eclipse.jst.server.tomcat.core, but thanks anyway (running ganymede on vista 32bit)

worked for me on 11.04 Natty Narwhal / Eclipse 3.6 Helios / default OpenJDK / Tomcat 6.0 24

Thanks! That also worked for me, using Eclipse Galileo with Tomcat 6 and Java 6 on Ubuntu 10.10. I'd spent a couple of hours trying to figure this one out. In addition to doing the above, I had Tomcat configured as a service, and also had to stop it from the command line (sudo service tomcat6 stop) in order to prevent a port conflict error when starting up my project from Eclipse.

This was exactly my problem too. I renamed my Tomcat 6.0.33 folder to something else, on purpose, to disable it, while trying to switch to Tomcat 6.0.35. And when I did that rename, I was unable to create a new Tomcat 6.0 server. The fix was to rename it back.

+1 Absolutely the solution I was looking for. Thank you so much!
