I actually did that to create a web commerce solution for my organization. In essence all I really did was take the jsp files and put them in different directories. Then added entries in the portlet.xml and liferay-portlet.xml files.

Of course I had to change some of the code in the jsp pages and create new references in the jsp files.

I split the portlet into the following portlets:

- browse
- cart
- catalogsearch
- check
- item
- navigation
- quickcart
- quickorderpad
- quickitemadd
- paidinvoices
- openinvoices

I created a directory for each portlet that I created. Then I put the jsp page in that directory with the name of view.jsp. If I had to initialize any variables (which was in the init.jsp in the shopping portlet) I created a new init.jsp. Of course I had to add entries in the web.xml file as well. Then I created an entry in portlet.xml and liferay-portlet.xml.

It was basically trial and error to see what errors I received while trying to use each component.

For example:
Checkout:
I still have a checkout_first.jsp, checkout_second.jsp and a checkout_third.jsp. But my main page is view.jsp and I have an init.jsp page.

The init.jsp page has the following:

<%@ include file="/html/portlet/webstore/init.jsp" %>

<portlet:defineObjects />

<liferay-theme:defineObjects />

<%
PortalPreferences portalPrefs = PortletPreferencesFactoryUtil.getPortalPreferences(request);

StorefrontPreferences storefrontPrefs = StorefrontPreferences.getInstance(company.getCompanyId(), portletGroupId.longValue());

Currency currency = Currency.getInstance(storefrontPrefs.getCurrencyId());

NumberFormat currencyFormat = NumberFormat.getCurrencyInstance(locale);

currencyFormat.setCurrency(currency);

DateFormat dateFormatDateTime = DateFormats.getDateTime(locale, timeZone);

NumberFormat doubleFormat = NumberFormat.getNumberInstance(locale);

doubleFormat.setMaximumFractionDigits(2);
doubleFormat.setMinimumFractionDigits(2);

NumberFormat percentFormat = NumberFormat.getPercentInstance(locale);

NumberFormat taxFormat = NumberFormat.getPercentInstance(locale);

taxFormat.setMinimumFractionDigits(3);

WindowState windowState = null;
PortletMode portletMode = null;

if (renderRequest != null) {
windowState = renderRequest.getWindowState();
portletMode = renderRequest.getPortletMode();
}
else if (resourceRequest != null) {
windowState = resourceRequest.getWindowState();
portletMode = resourceRequest.getPortletMode();
}

String currentURL = PortalUtil.getCurrentURL(request);
%>

They would have to be altered at least a little bit (depending on how you are going to group them). Each portlet would have to be stand alone.

At a minimum:
So you would have to make sure that each portlet has it's own initialization (basically replacing the init.jsp's role or duplicate the same init.jsp in each portlet). You would have to remove the references to the pages that you are splitting into new portlet. So if you wanted the checkout to be a separate portlet then you wouldn't want the other portlets to try to load the checkout function inside of it.

I keep like portlets in the same war file. So I like to organization the portlets in their own directory. I think I got that format from Liferay's source code.

html/portlet/cart
html/portlet/browse
etc.

Your java classes need to be in the docroot\WEB-INF\src directory (if you are using the plugin environment), while your jsp files should be somewhere under docroot (Not under the WEB-INF directory).

How comfortable are you with writing java applications.

Do you like using an ide or are you a text source code editor?

And which development environment are you using.

You add a reference to the jar files in Liferay. In the plugin sdk there is a file called app.server.username.properties. That files tells the development environment where all of the liferay files are. So you don't have to import the classes into your project.

What where the portlets that you wanted to split the shopping portlet into?

Catalog
Checkout
?

Hello Albert,

Did you use ext enviornment to break shopping portlet in multiple portlets?
Did you create your own action classes or used the exsisiting ones for the portlets?

I am little confused in how exsisting shopping portlet should be divided in terms of enviornment.Since this is an exsisting portlet, it should be done in ext env.


thanks
