Fixing 1 property on nodes in content
First of all locate all of the data I need :-
path=/content/catalogs/XXX/v1/master/collections
1_property=sling:resourceType
1_property.value=commerce/components/section
2_property=@target/pageInformation
2_property.operation=exists
2_property.value=true
p.limit=-1
p.hits=selective
p.properties=jcr:path target/pageInformation
This gives me a JSON output. Put the JSON output in a file and transform the file :
perl -pe 's/},{/\n/g' < raw_data.json > raw_data.txt
I now have line separators. Edit the raw_data.txt and remove the first line, relating to "success" of the query.
Run the following Perl program to generate curl commands which will put the data on to the target CQ instance :-
#!/usr/bin/perl
sub trim($)
{
my $string = shift;
$string =~ s/^\s+//;
$string =~ s/\s+$//;
return $string;
}
open (FILE, 'raw_data.txt');
while (<FILE>)
{
chomp;
($jcr_path_data, $page_information_data) = split("\",\"");
($rubbish1, $target_path) = split("\":\"", $jcr_path_data);
($rubbish2, $page_information) = split("\":\"", $page_information_data);
$target_path =~ s/"//g;
$page_information =~ s/"//g;
if ($page_information =~ /^''''''''/)
{
$page_information =~ s/^''''''''/''''en''''/;
}
$TARGET_HOST="localhost:4502";
$TARGET_USER="admin";
$TARGET_PASS="admin";
$CURL_CMD = "/usr/bin/curl -u \"" . $TARGET_USER . ":" . $TARGET_PASS . "\" -F \"_charset_=UTF-8\" -F \"pageInformation=" . $page_information . "\" \"http://" . $TARGET_HOST . "$target_path/target\"";
print ($CURL_CMD) . "\n";
#system($CURL_CMD);
print "\n"; print "\n";
}
Redirect the output of this to a separate file & then execute that file. This way we have a record of the commands that were executed.
Note, that the form field name "_charset_=UTF-8" allows you to post accented characters. This way you can use curl to HTTP POST data in the correct charset to Apache Sling. See the "Character Encoding" section of : Apache Sling - Request Parameter Handling in Sling

Reading Cookies & Encrypting data
Below is a little bit of code to loop through cookie data.
It also adds a cookie whose data has been encrypted by CQ. And, decrypts it too.
<%@ include file="/libs/foundation/global.jsp" %><%
%><%@ page contentType="text/html; charset=utf-8"%><%
%><%@ page import="org.apache.commons.lang.StringUtils"%><%
%><%@ page import="javax.servlet.http.Cookie"%><%
%><%@ page import="com.adobe.granite.crypto.CryptoSupport"%><%
%>
<h1>Cookie example</h1>
<%
CryptoSupport cryptoSupport = sling.getService(com.adobe.granite.crypto.CryptoSupport.class);
// Create an encrypted string of the data.
String str1 = cryptoSupport.protect("Helloooo");
// Base 64 encode the encrypted string so that only permitted Cookie data is stored.
Cookie ck1 = new Cookie ("testCookie", java.net.URLEncoder.encode(str1));
// Additional protection - only send the cookie over HTTPS
//ck1.setSecure(true);
// Additional protection - do not let JavaScript access this Cookie
//ck1.setHttpOnly(true);
slingResponse.addCookie(ck1);
// List out all of the Cookies, including decrypting our special Cookie.
Cookie[] cookies = slingRequest.getCookies();
if (cookies != null)
{
for (Cookie ck : cookies)
{
if ("testCookie".equals(ck.getName()))
{
%><p> <strong><%= ck.getName() %></strong> == <%= cryptoSupport.unprotect(java.net.URLDecoder.decode(ck.getValue())) %></p><%
}
else

How to use a Maven project to create a content package for CQ
-->
How to use a Maven project to create a content package for CQ (or more specifically Sling)
This articles
describes how to get hold of an example Maven project for creating a content
package; how to use it to install a content package; and, a little bit of
explanation of the POM provided.
Here are some important summary items.
- Use the Maven archetype facility to download the sample.
- The “packaging” directive must be set to “bundle”.
- Use <Sling-Initial-Content> to define the content nodes to be installed.
- See: sling.apache.org/site/content-loading-jcrcontentloader.html
Downloading the sample Maven project

Anatomy of the POM
The above section
showed how to get the example maven project for a CQ (more specifically a
Sling) content package.
Now follows an
analysis of the produced POM.
Standard first 3
lines :-
<?xml version="1.0" encoding="ISO-8859-1"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
Now, our project specific information (NB, this
appears in Felix bundles).
<groupId>com.mkalugin.cq5</groupId>
<artifactId>test-wibble</artifactId>
NB, Packaging is specified as "bunlde",
this will be an OSGi bundle (not a CRX package).
<packaging>bundle</packaging>
<version>1.0-SNAPSHOT</version>
<name>test-wibble</name>
<description>com.mkalugin.cq5 - test-wibble</description>
Now comes the maven-bundle-plugin definition -
this does the work of creating an OSGi Sling bundle with instructions of how to
install (or uninstall if you with) the content nodes.
<build>
<plugins>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<version>2.3.7</version>
Now comes the details of the content nodes and
what we want to do with them.
<configuration>
<instructions>
<Sling-Nodetypes>
SLING-INF/nodetypes/nodetypes.cnd
</Sling-Nodetypes>
<Sling-Initial-Content>
SLING-INF/scripts;overwrite:=true;uninstall:=true;path:=/apps/my/node,
SLING-INF/content;overwrite:=true;uninstall:=true;path:=/content
</Sling-Initial-Content>
</instructions>
</configuration>
</plugin>
</plugins>
</build>
An autoInstallBundle profile is given by default
showing how the produced bundle can be loaded & installed in to Felix.
This is documented at : http://sling.apache.org/site/content-loading-jcrcontentloader.html
<profiles>
<profile>
<id>autoInstallBundle</id>
<build>
<plugins>
<plugin>
<groupId>org.apache.sling</groupId>

A detailed analysis of a Maven POM for an Adobe CQ5 OSGi Bundle
This article describes everything about the
Maven POM which is used to build an OSGi Bundle for CQ5.
Define project specific attributes:
The properties section defines some variable which we use further on within the POM.
This following section of profiles defines
some Quality Assurrance processes which can be optionally used within the
project:
Important summary items
- The “packaging” directive must be set to “bundle”.
- Look at the bundles listed in Felix and make sure that your dependency list specifies the correct version numbers.
- Version numbers are becoming mandatory, so always specify them.
- The encoding for source & target files can be set in a global <encoding> property & will apply throughout your build.
- Use profiles to define different installation locations (not shown here).
POM.xml
The POM first line, complete with name-spaces :-
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd">
Tell Maven which model version of the
POM this is:
<modelVersion>4.0.0</modelVersion>
Define project specific attributes:
<groupId>com.day.cq5.lily</groupId>
<artifactId>lily-cq5-core</artifactId>
<version>0.0.2-SNAPSHOT</version>
<name>CQ5 Lily Core</name>
<description>Contains the blah blah.</description>
The packaging definition is very
important!! This tells maven about the
output format that it must produce (in order to produce an OSGi bundle, we need the
maven-bundle-plugin):
<packaging>bundle</packaging>
The properties section defines some variable which we use further on within the POM.
<properties>
<encoding>utf-8</encoding>
<devserver>http://localhost:4502/system/console/install</devserver>
<devuser>admin</devuser>
<devpassword>admin</devpassword>
</properties>
Next, we tell Maven to use our local CQ5
instance as a repository of dependencies (an Archiva repository). You need to install the CQ Archiva servlet (see dev.day.com).
<repositories>
<repository>
<id>localinstance</id>
<name>CQ 5.x localinstance</name>
<url>http://localhost:4502/maven/repository</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>localinstance</id>
<name>CQ 5.x localinstance</name>
<url>http://localhost:4502/maven/repository</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</pluginRepository>
</pluginRepositories>
The above is optional – if you have access to a
full repository, then maybe use that instead.
This could be defined in settings.xml but is kept here so that it is
visible to this project.
We now take a look at the build definition
for the OSGi bundle.
This is driven by the defined plugin
definitions which have goals that default to the default Maven life cycle
phases.
The compiler plugin controls the javac
compilation. Note that java 1.5 is used
by default therefore, here we have specified the use of Java 1.6.
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.5.1</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
The bundle plugin controls the packaging
of the output in to an OSGi bundle. The
key element here is the Export-Package element which defines the package that
we want to expose in OSGi. There are
lots of additional items that can be specified here to avoid clashes with other
classes loaded by the class-loader.
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>2.3.7</version>
<extensions>true</extensions>
<configuration>
<instructions>
<Export-Package>
com.day.cq5.lily.util.*;
version=${project.version}
</Export-Package>
</instructions>
</configuration>
</plugin>
The sling plugin is used to install the
bundle in to the local CQ instance.
Note, it would probably be better to define this configuration within a
profile definition so that the bundle could be installed on other CQ5 instances
(such as SIT or UAT environments):
<plugin>
<groupId>org.apache.sling</groupId>
<artifactId>maven-sling-plugin</artifactId>
<version>2.1.0</version>
<executions>
<execution>
<id>install-bundle</id>
<goals>
<goal>install</goal>
</goals>
</execution>
</executions>
<configuration>
<slingUrl>${devserver}</slingUrl>
<user>${devuser}</user>
<password>${devpassword}</password>
</configuration>
</plugin>
</plugins>
</build>
The following section defines the Java
bundles that our code is dependent upon.
Note that there are some commented out dependencies which are not
required in the demonstration package but, which you will probably need at some
time or other.
<dependencies>
<dependency>
<groupId>com.day.cq.wcm</groupId>
<artifactId>cq-wcm-api</artifactId>
<version>5.5.0</version>
