Maven Proxy Settings don't work!?

Maven Proxy Settings don't work!?

Tried lot of settings.xml alterations and still maven cant update its repository?? Try this

Step

1. Download  : Cntlm Authentication Proxy from here 
2.Install and Configure it with your proxy details.
3. Run it like this cntlm.exe -v -a NTLMv2 -c cntlm.ini
4. Now configure back your settings.xml under .m2 like

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
<localRepository />
<interactiveMode />
<usePluginRegistry />
<offline />
<pluginGroups />
<servers />
<mirrors />
<proxies>
<proxy>
<id>myproxy</id>
<active>true</active>
<protocol>http</protocol>
<host>localhost</host>
<port>3128</port>
</proxy>
</proxies>
<profiles />
<activeProfiles />
</settings>

Thats it now you can run your maven commands from console or update the user settings in eclipse to make maven fetch the required jars or reindex them.

Happy Coding..!

Solved : No configuration found for the specified action

Solved : No configuration found for the specified action 

Issue: Warning : No configuration found for the specified action on struts 2 action call..

Fix : Check your struts.xml and action mapping and map it with your jsp form submission

for example,

Action mapping 

<action name="login" method="login"

class="com.tcs.ecmui.action.CredentialWatcher">

<result name="success" type="redirect">getAllPages</result>

<result name="error">/resources/jsp/login.jsp</result>

</action>

..

.. 

<package name="readNode" extends="struts-default,json-default" namespace="/">

</package>

Jsp

<s:form action="login" method="POST">

<s:textfield name="user" label="User" />

<br>

<s:password name="password

Problematic Code :

<s:form action="/login" method="POST">

<s:textfield name="user" label="User" />

<br>

<s:password

or

<s:form action="/login.action" method="POST">

<s:textfield name="user" label="User" />

<br>

<s:password

Struts 2 Rest Convention Plugin Configuration Example

Struts 2 Rest Convention Plugin Configuration Example

I was playing around with Struts 2.3.8 and I really liked it the way apache has bundled it with lots of plugins that can help developers shrink their coding efforts hugely.

I was trying with conventions plugin and a simple struts action. The action was not loading saying there is no mapping found.. After couple of tries I could make it work.. Posting the same if some one might find it helpful in saving time..

Action

    @Result(name="success", type="redirectAction", params = {"actionName" , "authentication"})
})

Manually Start PostgreSQL Windows

Start PostgreSQL in Windows

Download and install/extract the postgre server

Create a data folder under pgsql as
C:\softwares\installed\pgsql\data

Open command prompt and Navigate to the extracted/installed folder,

For Example
C:\softwares\installed\pgsql\bin

and type the following command



pg_ctl -D C:\softwares\installed\pgsql\data -l logfile start

finally,
type initdb.exe C:\softwares\installed\pgsql\data for initializing the database

Javascript for loop Example

Javascript for loop Example

for(var i=0; i<=10; i++){
    alert("Counter is at "+i);
}

What to note??
From java only a small but confusing difference :

In Javascript it is :

for(var i=0;

Where as in java it is something like for(int i=0; ......... Being a java developer you will be tempted to use int i instead of a var declaration..

Example..

for(var i=0; i<=arr.length; i++){
var property = arr[i].split("=");
var propertyName = property[0];
var propertyVal = property[1];
        //... continue custom logic
 }

Alfresco - view state cannot be reconstructed

Alfresco - view state cannot be reconstructed 

This is a very familiar exception for Alfresco users,

Cause:

There are a lot of reasons for this exception and is noticed in Alfresco Explorer. The causes for this vary from
1. User session expiry, 
2. applying amp file, 
3. UI customizations
4. Wrong configs etc.

As per Alfresco, this is a message/exception "specially for developers". And for those who wants the details needs to refer the system logs on where it went wrong.. However few of the issues causing these has been fixed in 4.1x version of Alfresco.

By Alfresco SDK

From Alfresco Explorer

Hover the content

Hovering the content item in Alfresco displays its target url embedded with a servlet with its node id. Check lower left corner of your browser.. (I use google Chrome!?). Copy the target url and paste it in a notepad to make it how you want..

The same can be found in download link of the content and few of the other actions associated with it

Node Browser

Click on the Administration Console button in your Alfresco Explorer on which you can find Node Browser option.

Selecting the corresponding stores, you will be listed with contents(or Alfresco nodes) along with their node details.

Alfresco Share

Hover works with Share too but only has got a slightly different url mix up. Copy the target url and paste it in a notepad to make it how you want..

The same can be found in download link of the content and few of the other actions associated with it

Navigate to the desired content to get its detail.

Javascript API

Scriptnode holds a property “id” for storing the node id of an alfresco node.

 var name1 = userhome.properties.id

 var name2 = userhome.properties["id"];

 var name3 = userhome.properties["cm:id"];

 var name4 = userhome.properties["{http://www.alfresco.org/model/content/1.0}id"];

Any many API calls returns such nodes which can be iterated and accessed like above.

Query

var newquery = "PATH:\""+ result3 + "//*\" AND @cm\\:name:\"" +model.node.name +"\"";

model.result = newquery;

var nodes = search.luceneSearch(newquery);

Alfresco SDK

The class NodeRef holds the detail of nodes. Many SDK calls returns NodeRef or its array as response. Iterate over it and fetch the node.id

for (NodeRef node : nodes)

{..}

Why???(Solution)

Just wrap it with the right DTD something like below,

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE properties[
<!ELEMENT node (name, id, path, icon16, icon32, isFolder, title, description, author, size, creator, created, modifier, modified, editinline, encoding, mimetype, content, extranetId, templateId, docstatus, containerId)>
