Running Multiple Eclipse J2EE Workspaces with multi-instance JBoss configuration


In my previous article I had explained how to configure JBoss for multi instance run. (If you have not configured your JBoss, please read to my previous article)


While running your Java project on JBoss through eclipse, we first need to create a server in eclipse which should point to your multi-instance configured JBoss.
* Then in its properties it will ask for few things like - runtime environment, Launch configuration details, server properties like JNDI port, HTTP port, server configuration.
* So as shown in above screen shot, fill in your proper values.
a. For HTTP port, JNDI port - refer to your binding xml file.
b. For server configuration, put name of your server configuration folder like node1, node2, all, minimal, etc.


**server configuration value is important because it will decide where to publish your jar/war/ear of current project (I mean in which server configuration directory).
**If you put this value wrong, then it will publish your project to some other JBoss instance.


There is one more way to edit these values,
go to your project workspace directory - then to 
<Project_workspace_directory>\.metadata\.plugins\org.eclipse.wst.server.core\servers.xml


and edit values like jndi port, port, serverConfig, start-timeout, stop-timeout, etc.




e.g. Server configuration folders would look like -


Now click on "open launch configuration", and in program and VM arguments, put values like - 
//In Program Arguments - 
-c default
-b 0.0.0.0
-Djboss.messaging.ServerPeerID=0

//In VM arguments (add this to existing arguments(optional-not required)) - 
-org.jboss.logging.Log4jService.catchSystemOut=false


which would appear like -


So now if I have opened one more eclipse workspace and I want to run this project on different JBoss instance then its server properties would look like


and its launch configuration would be like - 


Now consider if I open my third workspace, and if I want to run this project on another different JBoss instance then, its server properties and its launch configuration would look like - 



That's it.
In my next article, I will explain how to run (i.e.create, start and stop) each JBoss instance as a separate windows service. Before that please read my previous article How to run JBoss as windows service.


So, Have a Happy life and coding too :-)

How to install / Configure Mantis For Apache-PHP-PostgreSQL combination

How to install / Configure Mantis For Apache-PHP-PostgreSQL combination  → I wanted to write this blog a long back, but better late than never. Three years back I was working on a project where we had used Mantis Bug Tracker for managing our bugs list, for that, I had to install it on a server from where our teams could access it to log the software bugs and update the fixes. Important learnings - with new php versions, I faced few issues with postgresql configs, then while setting up database instance for mantis I faced few issues with postgres port configs and how to give it on mantis config files, database user grant problem. I had to set up everything from scratch so learned a lot. (Note - mantisbt  →  mantis bug tracker) Why I have written this post  →  at that time I could not find any resource on web which would give me good tutorial on how to install mantisbt on Apache and PostgreSQL. So I wanted to put it on web so others could some of thei...

Modified ExtJS LOVCombo (List of Values) ux plugin - with select all, deselect all, text filter, bubble up and bubble down of selection

Image
Here is one interesting modification to LOVCombo ux plugin in ExtJS 3.4. The original ExtJS ux Lovcombo i.e.Ext.ux.form.LovCombo plugin was developed by Jozef Sakáloš and can be still found at  http://lovcombo.extjs.eu/ . In Ext 4.x onwards, similar modifications can be applied to combo-box through plugin property. Following modification to Ext.ux.form.LovCombo, enables it to have "Select All", "Deselect All", "Text Filtering on values", "bubbling up and down of selection events". Its just a toolbar added in xtemplate of combo-box's dropdown list, and this toolbar has all these buttons, filter text-fields, etc. Here is how it looks like - It has five features - 1) Select All / Deselect All checkbox - to check/uncheck all values and its not part of your data, so selection / deselection logic is separate from user's data. 2) Text Filter - In case of long lists, this will be handy, to filter out values and select /deselec...

Twin Trigger and Twin Trigger Combobox in ExtJS,  How to give qtip / quicktip / tooltip to Twin Trigger Field In ExtJS, there is a class Ext.form.TwinTriggerField (though its an abstract class) which is used to create objects of TwinTrigger, and can be extended to form n-trigger field.  Depending upon the requirement it can be easily, modified. Basically DateField and ComboBox are the examples of single trigger Textfield. Simple TwinTriggerField  Here is sample code how to use basic TwinTriggerField (which is basically a Textfield with two triggers/buttons which can be assigned different handlers) - new Ext.form.TwinTriggerField({ id : 'twintrigger', fieldLabel : "TwinTrigger", //Custom icon-classes for triggers trigger1Class : 'x-form-clear-trigger', //trigger2Class : 'customTriggerIcon', //Enable Key events over textfield enableKeyEvents : true, //Separate Trigger handlers onTrigger1Click : function(fie...
