Eclipse javaw.exe hanging at startup (49% cpu), regardless of task - eclipse

It was hanging on refreshing workspacing, specifically refreshing files in /target/classes in a project. I renamed that folder and now it hanging on the next progress item: Initializing Java Tooling.
I a unable to start elcipse. If clicking on expanding one of the projects in project view, it stops responding and javaw.exe needs to be killed.
This is on Windows XP
This is Eclipse Indigo

This may help
In your eclipse,
1) Go to Help
2) Click Eclipse marketplace
3) search - optimizer
install "optimizer for eclipse"

This works (the first AND second method)

Eclipse makes window explorer go slow

I started using eclipse today. I downloades from the page, this version Eclipse IDE for Enterprise Java and Web Developers, and suddenly, after using eclipse windows explorer starts going slow, it takes like 5 minutes to load a folder, and even if i close eclispe this problem is still there. I can't uninstall and reinstall because it was a zip archive not an executable. If i restart the computer, everything goes perfect, but afer i open eclipse one i can't even make right click on the desktop to creat a file, because it gets stuck.
No idea how to solve it. Any tips?

Eclipse Mars will not open (Windows 7)

When I attempt to open Eclipse Mars, absolutely nothing happens. I don't get prompted to select my workspace or anything.
I've seen people run into this problem after update from Luna to Mars but I've been using Mars for a while now and this only just started happening today.
I've removed any software and undone any updates that could have potentially caused this to happen but it's still occurring.
What could cause this to happen?
Kill if there is any existing process of eclipse.exe and javaw.exe from background using task manager and try to run eclipse as administrator.
It could be due to lack of permission.
Check the YOUR_WORKSPACE_PATH/.metadata/.log file for exceptions. Moreover, I would add the system property -Dosgi.clean=true to the eclipse.ini file (this property enforces the cleanup of the OSGi cache).

Eclipse hangs on startup, but second eclipse instance works

I use Eclipse Java EE IDE Kepler for Web Developers with pydev.
The first instance of Eclipse hangs on startup while loading a workspace.
If i start eclipse again, a coexist second instance of eclipse works fine.
I used different workspaces, the problem is independent from the used workspace.
Thanks
I think that the best approach would be identifying the stack you have when it hangs and then reporting a bug (probably in Eclipse: https://bugs.eclipse.org/ but it may be in PyDev: https://sw-brainwy.rhcloud.com/tracker/PyDev depending on the trace).
On http://pydev.org/faq.html#PyDevFAQ-HowdoIReportaBUG%3F there's info on how to get information on a halting condition.

eclipse tomcat 7.0

I'm trying to set up an Apache Tomcat 7.0 server in Eclipse, but I can't get the wizard to let me create it. My NEXT button won't highlight after I select Tomcat v7.0 like so:
I don't have the same problem trying to create any other version of Tomcat, just v7.0:
Info about my system:
-I've had it up and running previously, but had to go through a reboot with my system, Eclipse was untouched as it was on a different HDD
-I've reinstalled Tomcat 7.0 twice, once to the drive containing this particular Eclipse Workspace, and once to my main OS drive, both to no avail.
Can anyone tell me what I did wrong here or what's going on here?
Thank you very much.
In your eclipse menu go to
window > server > runtime environments > hit add > select tomcat 7 > hit next
press browse and navigate to the installation directory
and finish. Will solve this issue.
Close Eclipse
In {workspace-directory}/.metadata/.plugins/org.eclipse.core.runtime/.settings delete the following two files:
org.eclipse.wst.server.core.prefs
org.eclipse.jst.server.tomcat.core.prefs
Restart Eclipse
1.Close Eclipse
2.In {workspace-directory}/.metadata/.plugins/org.eclipse.core.runtime/.settings. delete the following two files:
org.eclipse.wst.server.core.prefs
org.eclipse.jst.server.tomcat.core.prefs
3.Restart Eclipse

errors on eclipse startup (WebDev + JBoss Tools + Tomcat)

i'm running into following errors everytime i start eclipse. If i move my project to a new workspace, everything works fine for the duration of one session - as soon as i open eclipse for the next time, the same thing is popping up again.
I tried various suggestions i found in other posts (closing/reopening project, validation, cleaning,etc.) without success. Here is my stacktrace from the last session (its too long to post it directly in here:))
The main symptom is that Tomcat doesnt start - it is stuck at 7%.
Thank you guys in advance, your help is highly appreciated!! If you need anything else, just leave me a comment and i i'll post it!
Your Eclipse environment is seriously messed up. Perhaps you installed plugins the wrong way or you used the wrong Eclipse or plugin version.
Trash everything. Delete the Eclipse program folder altogether. You can keep your workspace folder, but you should delete its .metadata folder. Now download a fresh copy of Eclipse for Java EE (note, with the EE!), extract it and then integrate Tomcat again the usual way by the Servers view. Note that you don't need any additional plugins for this step.
JBoss Tools should be installed via Help > Install New Software. You should specify the JBoss Tools update site matching the exact Eclipse version. Currently it's Indigo SR2, so you should specify http://download.jboss.org/jbosstools/updates/indigo/SR2/ as URL.
