Eclipse: Install Plug Ins

If one can connect to internet, it is easy to install Eclipse Plug Ins.
Go to "Help" --> "Install New Software" --> enter url in "Work With"

But what to do when it is not possible to connect to Internet from Eclipse?

two ways:
(1) find the plug in Zip, download it to local, then use
"Help" --> "Install New Software" --> click on "Add" beside "Work With",
click on "Archive" , select the zip file from your local disk, then Open it.


(2) find the internet proxy which can be used to access internet.
Or use Fiddler (IE browser web debugging tool) to find the proxy Fiddler is using and configure in Eclipse to use it to access the plug in web sites.

Eclipse View Installation Detail

To view installation detail for Eclipse, go to "Help"-->"About Eclipse Platform" --> Click on button "Installation Details".  --> click on "Configuration"

Use SVN with Eclipse

Subversion (SVN) is a popular replacement for CVS, offering improved performance (courtesy of intelligent local caching and a database back end), easy and fast branching, and an answer to every one of the shortcomings that people often run into while using CVS.

Weblogic wldeploy:Exclusive access to the edit lock

I have encountered this issue lately.
When deploying an application in weblogic, I received error:  The following solution resolved the issue.
Original post from:
http://adfhowto.blogspot.ca/2011/07/troubleshooting-domain-edit-lock-is.html

Error

[Deployer:149163]The domain edit lock is owned by another session in non-exclusive mode - this deployment operation requires exclusive access to the edit lock and hence cannot proceed. If you are using "Automatically Aquire Lock and Activate Changes" in the console, then the lock will expire shortly so retry this operation.

Solution

Actually what Deployer is trying to tell you is that it tried to deployed but another user has Lock and Edit the domain . More regarding Lock and Edit in this related post.

In other not to fail but exist gracefully leaving you deployment to be applied when the Lock is released, then use nonexclusivelock option.

Using this option you ll get the following message, if another user has avquire the lock and the script will not fail:
[wldeploy] Operation is pending and will be activated or cancelled when the ongoing edit session is activated or cancelled. 


In case if you use a wldeploy ant task, here is an example script

<project name="deploy" default="deploy">
<property file="deploy.properties" />

<!-- Setting TaskDefinition -->
<taskdef name="wldeploy" classname="weblogic.ant.taskdefs.management.WLDeploy">
    <classpath>
        <pathelement location="${wldeploy.home}/weblogic.jar"/>
    </classpath>
</taskdef>
<!-- Deploying Applications  -->
<target name="deploy">
<wldeploy action="deploy"
          name="${deploy.name}"
          source="${deploy.source.path}/${deploy.source.ear}"
          verbose="true"
          adminurl="${connection.protocol}://${wls.hostname}:${wls.port}" 
          targets="${deploy.target}"
          upload="true"
          user="${wls.username}"
          password="${wls.password}"

view the content of a keystore

The following commands allows you to see how many entries are in a keystore:

E:\>keytool -list -keystore E:\SSL_Cert\TempKeyStore.jks

Enter keystore password:

Keystore type: JKS

Keystore provider: SUN

Your keystore contains 3 entries

Java Keytool Commands for Checking

If you need to check the information within a certificate, or Java keystore, use these commands.

• Check a stand-alone certificate keytool -printcert -v -file mydomain.crt
  
• Check which certificates are in a Java keystore keytool -list -v -keystore keystore.jks
  
• Check a particular keystore entry using an alias keytool -list -v -keystore keystore.jks -alias mydomain
  

For more detailed info on keystore and import keys, refer to:

Kill a process in windows with PID

taskkill /im myprocess.exe /f

The "/f" is for "force". If you know the PID, then you can specify that, as in:

taskkill /pid 1234 /f

Lots of other options are possible, just type taskkill /? for all of them. The "/t" option kills a process and any child processes; that may be useful to you.
