As part of opentaps 1.4, we are introducing Java actions for the ofbiz screen widget based on [https://issues.apache.org/jira/browse/OFBIZ-44 OFBIZ-44]. This allows you to write the data preparation logic of a screen in Java instead of scripting languages.

To use this feature, in your screen widget XML, use the <tt>java</tt> directive to invoke your Java class and method:
<pre>
<screen name="findAndListInvoices">
<section>
<actions>
<java location="com.opensourcestrategies.financials.invoice.InvoiceActions" invoke="findInvoices"/>
</actions>
</pre>

Your Java method must be a static method which accepts a Map of the context as a parameter:
<pre>
public static void findInvoices(Map<String, Object> context) throws GeneralException, ParseException {
</pre>

The context contains environment variables as well as parameters for your screen. Opentaps has an <tt>org.opentaps.foundation.action.ActionContext</tt> which takes the Map and allows you to obtain environment variables from it and put values back into the context for your screen:
<pre>
final ActionContext ac = new ActionContext(context);
// ... for example
String invoiceTypeId = ac.getString("invoiceTypeId");
// ... for example
ac.put("processingStatuses", processingStatusList);
</pre>
