Issue in install package :

       We got app managed package installation failed error like "Missing Organization Feature: CommonPortal null" ,  and we received the below error mail 

"Your request to install package "********" was unsuccessful. None of the data or setup information in your salesforce.comorganization was affected.
If your install continues to fail, contact Salesforce CRM Support through your normal channels and provide the following information.

Organization: *****************

User: *************

Package: ***********

Problem:
1.  Missing Organization Feature: CommonPortalnull"

Solution:

       After  done the much analysis (create number of packages in personal org and change the code snippets) , came to know that the issue is due to "IsportalEnabled" standard field in User object.
       
       The issue has been resolved after we removed the field (IsportalEnabled) reference from the all the components. After that we able to install the package in customer orgs.

      Else  on workaround is, the "Common portal" license need to enable at client level to resolve the issue. (setup->customize->Customer Portal->Settings->Enable).

Regular Expression Powerfull sample in java

 We can use regular expression and to do large set of works as simple and single line code .

In this example i will show you how the regular expression play a vital stage .
I want to read a file and insert a new line (\n) at every 100 th character in that file content and write those changes in another file.

Normally what i did first is written a code to read file line by line and written a sample piece of code to read position and insert the new line in that particular position then written in new file.

Instead for write separate function i write an replaceAll with regular expression.

The sample code given below,

package com.shinnedhawks;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;

public class REPower {
    public static void main(String[] args) {
        new REPower().replace();
    }

    public void replace() {
        String oldFileName = "abc.txt";
        String tmpFileName = "abcnew.txt";

        BufferedReader br = null;
        BufferedWriter bw = null;
        try {
            br = new BufferedReader(new FileReader(oldFileName));
            bw = new BufferedWriter(new FileWriter(tmpFileName));
            String line;
            while ((line = br.readLine()) != null) {
                line = line.replaceAll("(.{100})", "$1\n"); // Here is the code it simplefied that largest code in single
                bw.write(line);
            }
        } catch (Exception e) {
            return;
        } finally {
            try {
                if(br != null)
                    br.close();
            } catch (IOException e) {
                // handle code
            }
            try {
                if(bw != null)
                    bw.close();
            } catch (IOException e) {
                // handle code
            }
        }
        // Once everything is complete, delete old file..
        File oldFile = new File(oldFileName);
        oldFile.delete();

        // And rename tmp file's name to old file name
        File newFile = new File(tmpFileName);
        newFile.renameTo(oldFile);

    }
}
