Is there an UML editor for Eclipse? An Eclipse Modelling project-based UML editor can be installed from the Eclipse update site "Modelling > UML2 Tools SDK". See Creating UML 2 diagrams with Eclipse UML2 Tools - Tutorial for an introduction.

How do I debug Eclipse? How can I see what plug-ins are being started? Why aren't the plug-ins I installed showing up in the UI? How do I start the OSGi console?

Debugging OSGi Bundle Loading Issues There are a few flags you can pass to Eclipse on the commandline or in your eclipse.ini file that might help: -consolelog - log everything in workspace/.metadata/.log to the console where you launched Eclipse as well -debug - more verbose console output -console - start the Equinox OSGi console to interact with OSGi directly -noexit - when Eclipse closes, keep the OSGi console running until you type 'exit' or hit CTRL-C so you can keep debugging See Where Is My Bundle? for an overview of how to use the OSGi console for diagnosing problems.

Debugging Eclipse Using Eclipse You can also debug an Eclipse instance from another instance through remote debugging: Start the instance to be debugged with "-vmargs -Xdebug -agentlib:jdwp=transport=dt_socket,server=y,address=8000". You should see a message like "Listening for transport dt_socket at address: 8000" Open Run → Debug Configurations... and create a Remote Java Application configuration with connection type "Socket Attach" and connecting to the client at port 8000. Set the project to a bundle project with the right dependencies for the bundles that you are trying to debug. Launch the configuration. The JDWP agent supports other useful arguments, like "suspend=n" so that the process does not suspend. For more details, see Oracle's Java Debug Wire Protocol (JDWP) connection docs.

I just installed Eclipse on my 64-bit system, but it does not start. What is the problem? Make sure that you have downloaded the 64-bit version of Eclipse (it should have x86_64 somewhere in its name) and have installed a 64-bit JVM. Likewise, if you run a 32-bit JVM, then you should use the 32-bit version of Eclipse.

When I start Eclipse it says "Workspace in use or cannot be created, choose a different one.", what should I do? There are a couple of things you can try. Delete the workspace/.metadata/.lock file. Check your running processes to make sure there aren't any remaining Java or Eclipse processes running. When in doubt, restart your computer. :) Try starting Eclipse on a different workspace (from the workspace selection dialog, or by using a command line argument like -data /home/user/tmp-workspace), then switch back to your original workspace.

How do I uninstall a plug-in? You can view your list of installed software by checking your installation details from about dialog. Help > About > Installation Details

Eclipse seems to be hanging on startup. How can I find out why? If none of the solutions outlined in this section reveal the problem, then you can try debugging an Eclipse instance as a debug target from another Eclipse instance. This is surprisingly easy: Start Eclipse in a "new" blank workspace (e.g., C:\TEMP\WS, or /tmp) Create a new Debug configuration: Run -> Debug Configurations; then click on "Eclipse Applications" and select the New Launch Configuration. If you believe it's something about a particular workspace, then set the workspace to your normal workspace. If you believe the hang is caused by a particular plugin, disable the plugin and verify. Launch and then see. Using this approach, you can break with the debugger to see where hangs are occurring. You can also change the selection of plugins that the instance is launched with.

I was working on a project and doing something or other does not work. Where should I start? Try refreshing your projects. Try cleaning your your projects using the menu item Project/Clean to trigger a rebuild. Try closing/reopening your projects. Try restarting Eclipse.

4.2 Where are Eclipse's log files located?

Where are Eclipse's log files located? <workspace>/.metadata/.log You can view this workspace log as a view if you have PDE installed on your computer (which you would if you have downloaded the Eclipse SDK). You can open that view via Window -> Show View -> Other -> PDE Runtime -> Error Log. <eclipse install>/configuration/<sometimestamp>.log <eclipse install>/configuration/org.eclipse.update/install.log

Session ID Name Fingerprinting

Session ID Properties

Session ID Entropy

must be unpredictable (random enough) to prevent guessing attacks

good PRNG (Pseudo Random Number Generator) must be used

must provide at least 64 bits of entropy

Session ID Content (or Value)

content (or value) must be meaningless

identifier on the client side

meaning and business or application logic associated to the session ID must be stored on the server side

session objects or in a session management database or repository

create cryptographically strong session IDs through the usage of cryptographic hash functions such as SHA1 (160 bits).

Session Management Implementation

defines the exchange mechanism that will be used between the user and the web application to share and continuously exchange the session ID

token expiration date and time

This is one of the reasons why cookies (RFCs 2109 & 2965 & 6265 [1]) are one of the most extensively used session ID exchange mechanisms, offering advanced capabilities not available in other methods

Transport Layer Security

use an encrypted HTTPS (SSL/TLS) connection for the entire web session

process where the user credentials are exchanged.

“Secure” cookie attribute

must be used to ensure the session ID is only exchanged through an encrypted channel

never switch a given session from HTTP to HTTPS, or viceversa

should not mix encrypted and unencrypted contents (HTML pages, images, CSS, Javascript files, etc) on the same host (or even domain - see the “domain” cookie attribute)

should not offer public unencrypted contents and private encrypted contents from the same host

www.example.com over HTTP (unencrypted) for the public contents

secure.example.com over HTTPS (encrypted) for the private and sensitive contents (where sessions exist)

only has port TCP/80 open

only has port TCP/443 open

“HTTP Strict Transport Security (HSTS)” (previously called STS) to enforce HTTPS connections.

Secure Attribute

instructs web browsers to only send the cookie through an encrypted HTTPS (SSL/TLS) connection

HttpOnly Attribute

instructs web browsers not to allow scripts (e.g. JavaScript or VBscript) an ability to access the cookies via the DOM document.cookie object

Domain and Path Attributes

instructs web browsers to only send the cookie to the specified domain and all subdomains

instructs web browsers to only send the cookie to the specified directory or subdirectories (or paths or resources) within the web application

vulnerabilities in www.example.com might allow an attacker to get access to the session IDs from secure.example.com

Expire and Max-Age Attributes

it will be considered a

and will be stored on disk by the web browser based until the expiration time

use non-persistent cookies for session management purposes, so that the session ID does not remain on the web client cache for long periods of time, from where an attacker can obtain it.
