I'm using Alfresco Community v5.2.0 to store some files (pdf, jpg/png essentially).
I'm creating a web app to retrieve this files.
I'm trying to create a grid of files from a specific folder in my application.
But when i'm retrieving the list of a specific folders with their thumbnails, the resolution of the thumbnail is very low (100x75).
How to configure Alfresco to generate a larger thumbnail ?
I tried to override the settings in :
C:\alfresco-community\tomcat\webapps\alfresco\cmisfs\stylesheets\
thumbnails.xsl
But this didn't work..
I'm using Alfresco on my computer (windows), with REST API call.
Where can i configure this resolution ?
Thanks in advance,

Ok I found a way to ovveride the thumbnail definition :
I created a file
thumbnail-service-context.xml
in
[AlfrescoRootFolder]\tomcat\shared\classes\alfresco\extension\
In this file I wrote :
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<!-- Slingshot Document Library image thumbnail options -->
<!-- Note that this will auto-register with parent="baseThumbnailDefinition" in the future -->
<bean id="thumbnailDefinitionDoclib" class="org.alfresco.repo.thumbnail.ThumbnailDefinition">
<property name="name" value="doclib" />
<property name="mimetype" value="image/png"/>
<property name="transformationOptions">
<bean parent="defaultImageTransformationOptions">
<property name="resizeOptions">
<bean parent="defaultImageResizeOptions">
<property name="width" value="900"/>
<property name="height" value="900"/>
<property name="allowEnlargement" value="false" />
</bean>
</property>
</bean>
</property>
<property name="placeHolderResourcePath" value="alfresco/thumbnail/thumbnail_placeholder_doclib.png" />
<property name="mimeAwarePlaceHolderResourcePath" value="alfresco/thumbnail/thumbnail_placeholder_doclib{0}.png" />
<property name="runAs" value="System"/>
<property name="failureHandlingOptions" ref="standardFailureOptions"/>
</bean>
</beans>
And now I can retrieve a thumbnail by calling :
/alfresco/api/-default-/public/alfresco/versions/1/nodes/{idDocAlfresco}/renditions/doclib/content

This is my spring-servlet.xml file. I am new to spring MVC. Do we need to define bean for HelloWorld.Controller. If i don't define will it work?
<bean id="viewResolver" class=" org.springframework.web.servlet.view. InternalResourceViewResolver" >
<property name="prefix">
<value>/WEB-INF/jsp/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
<bean name="/welcome.htm" class="com.vaannila.HelloWorldController" >
<property name="message" value="Hello World!" />
</bean>
</beans>
If i don't give this bean definition
<bean name="/welcome.htm" class="com.vaannila.HelloWorldController" >
<property name="message" value="Hello World!" />
</bean>
MyApplication should work or not? I am new to spring MVC. In few tutorial this code is there and in few its not there. Please explain.
Yes, you will need to define the bean (way to create instance of class) for all the Controller/Service/Dao/Components class you want to use and set relevant properties.
I would recommend you to use Annotation based configuration (spring boot) as it eases all this process. You can find lot of tutorials on getting stated with spring boot. Here is one such good tutorial https://www.mkyong.com/spring-boot/spring-boot-hello-world-example-jsp/
When I learnt about web scripts, the tutorials said to leave the Web Scripts folder alone and instead to add my web script to the Web Scripts Extensions folder. My understanding is that this is so that I do not pollute Alfresco's out-of-the-box web scripts, and upgrading will be easier.
Why is there no equivalent extensions folder for the Scripts folder?
Or is my understanding of the reason for the Web Scripts vs Web Scripts Extensions folders wrong?
Extension folders provide a way to override default behavior. You can put your code there if you like, but doing so makes it more difficult to override it. I will use the repository as an example. Similiar logic applies to share.
Have a look at alfresco/WEB-INF/classes/alfresco/web-scripts-application-context.xml. It reads:
<bean name="webscripts.store.repo.extension" parent="webscripts.repostore">
<property name="store"><value>workspace://SpacesStore</value></property>
<property name="path"><value>/${spaces.company_home.childname}/${spaces.dictionary.childname}/cm:extensionwebscripts</value></property>
</bean>
<bean name="webscripts.store.repo" parent="webscripts.repostore">
<property name="mustExist"><value>true</value></property>
<property name="store"><value>workspace://SpacesStore</value></property>
<property name="path"><value>/${spaces.company_home.childname}/${spaces.dictionary.childname}/cm:webscripts</value></property>
</bean>
<bean id="webscripts.repoclasspathstore" class="org.alfresco.repo.web.scripts.RepoClassPathStore" abstract="true" />
<bean id="webscripts.store" parent="webscripts.repoclasspathstore">
<property name="mustExist"><value>false</value></property>
<property name="classPath"><value>webscripts</value></property>
</bean>
<bean id="webscripts.store.alfresco" parent="webscripts.repoclasspathstore">
<property name="mustExist"><value>false</value></property>
<property name="classPath"><value>alfresco/webscripts</value></property>
</bean>
<bean id="webscripts.store.client" parent="webscripts.repoclasspathstore">
<property name="mustExist"><value>true</value></property>
<property name="classPath"><value>alfresco/templates/webscripts</value></property>
</bean>
<bean id="webscripts.store.client.extension" parent="webscripts.classpathstore">
<property name="classPath"><value>alfresco/extension/templates/webscripts</value></property>
</bean>
<bean id="webscripts.searchpath" class="org.springframework.extensions.webscripts.SearchPath">
<property name="searchPath">
<list>
<ref bean="webscripts.store.repo.extension" />
<ref bean="webscripts.store.repo" />
<ref bean="webscripts.store.client.extension" />
<ref bean="webscripts.store.client" />
<ref bean="webscripts.store.alfresco" />
<ref bean="webscripts.store" />
</list>
</property>
</bean>
The searchPath property of webscripts.searchpath shows the search order. Search terminates as soon as it has a match. As you can see, it is no problem to put custom code in non extension locations as long as their path is unique.
I personally only put override webscripts in extension locations.
You can create a folder under Scripts called Extension and put all your script in that. Or just create different folders under Scripts for each function or project, it doesn't matter. They get picked up by Alfresco.
I am using Spring MVC + FreeMarker integration. As I am new to FreeMarker i am not able to find out a way to configure FreeMarker labels from properties file.
Kindly help me out on this.
Thanks.
You can use, 'ResourceBundleMessageSource', message source for this.
<bean id="messageSource"
class="org.springframework.context.support.ResourceBundleMessageSource"
<property name="basename" value="classpath:messages/messages" />
<property name="defaultEncoding" value="UTF-8"/>
/>
Define the locale resolver,
<bean id="localeResolver"
class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
<property name="defaultLocale" value="en" />
</bean>
Define localeChangeInterceptor which detects the language parameter from the user session and call locale resolve. And register the interceptor in handler Mappings.
<bean id="localeChangeInterceptor"
class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="lang" />
</bean>
class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" >
<property name="interceptors">
<list>
<ref bean="localeChangeInterceptor" />
</list>
</property>
</bean>
Property files need to be defined like,
messages_en.properties
messages_ar.properties
inside the messages folder path.
'ReloadableResourceBundleMessageSource' can be used if the language property files frequently changes. That means you don't have to restart the application in each language file change.
You need to import spring macro,
<#import "/spring.ftl" as spring/>
and
messages can be accessed inside a .ftl as follows.
<#spring.message "customMessageKey"/>
I'm using Alfresco ECM to transform TIFF to PDF using the Tiger OCR library ()

When I import a TIFF file into the Company Home folder I now expect that content to be transformed into a PDF. Now am I right in assuming that the transformation is automatic or do I need to invoke a rule on the space ?
Also, I have set the logging on the transformation to DEBUG and this is what I see in Alfresco logs
DEBUG [util.exec.RuntimeExec]

Seems like its searching for a target of text/plain when I really need it to transform to PDF. What am I missing here ? Pls help
The only transform that'll be run automatically is the one to text plain, which is used for the full text indexing.
If you're using Share, then Share will try to do two more transformations for you. Firstly, it'll try to generate a thumbnail (via the rendition service) when you view the folder with your file in it. For this to work, you'd normally define a transformer from your new mime type to image/jpeg. Additionally, when you view the document details in Share, it'll try to give you a web preview.
If you'd like to have a PDF version of your document generated when you upload it, then you'll want to define a rule. You could do this with a transform content rule, or you could write a script to use the Rendition Service if you wanted a lot of control over it.
i have a properties folder and inside of ti contains my jdbc.properties file.
the problem is that i am unable to load it succesfuly as it always complains that it cannot locate the file.
i have the file currently sitting in the roo directopry fo WEB-INF. when i build and compile my spring mvc it does throw any exceptions but as soon as i load the beans from my code using new ClassPathXmlApplicationContext it fails and says it cannot locate my properties file??
here is how my beans look like:
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations"> <list> <value>/properties/jdbc.properties</value>
</list> </property> </bean>
<bean id="dataSource1" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${database.driver}" /> <property
name="url" value="${database.url}" /> <property name="username" value="${database.user}"
/> <property name="password" value="${database.password}" /> </bean>
here is a pic of my project structure at present:
You can put the properties files in root of classpath. And use like below.
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations"> <list> <value>classpath:jdbc.properties</value>
</list> </property> </bean>
