+ <para>
+ In this section, you will learn how to configure the
+ <emphasis role="italics">Upload service</emphasis>
+ that is defined by the
+ <code>org.exoplatform.upload.UploadService</code>
+ class.
+ </para>
+ <para>This can be configured with the following XML code:</para>
+ <informalexample>
+ <programlisting language="XML">
+ <component>
+ <type>org.exoplatform.upload.UploadService</type>
+ <init-params>
+ <value-param>
+ <name>upload.limit.size</name>
+ <description>Maximum size of the file to upload in MB</description>
+ <value>10</value>
+ </value-param>
+ </init-params>
+ </component>
+</programlisting>
+ </informalexample>
+ <para>This code allows uploading files with the default size limit (10MB). The default value unit is in megabytes.</para>
+ <para>This limitation will be used by default by all applications if no application-specific limit is set. Setting a different limit for applications is discussed in a later section.</para>
+ <para>
+ If the value is set to
+ <code>0</code>
+ , the upload size is unlimited.
+ </para>

+ <orderedlist>
+ <listitem>
+ <para>
+ Create an
+ <code>org.exoplatform.webui.form.input.UIUploadInput</code>
+ object type by using one of three following constructors:
+ </para>
+ <itemizedlist>
+ <listitem>
+ <para>The default constructor that allows uploading the file with the size of 10 MB.</para>
+ <informalexample>
+ <programlisting language="Java">
+public UIUploadInput(String name, String bindingExpression, int limitFile)
+</programlisting>
+ </informalexample>
+ </listitem>
+ <listitem>
+ <para>
+ This constructor allows you to customize the size limit of uploaded files by using the
+ <code>limitSize</code>
+ parameter. The default value unit is in megabytes.
+ </para>
+ <informalexample>
+ <programlisting language="Java">
+public UIUploadInput(String name, String bindingExpression,int limitFile, int limitSize)
+</programlisting>
+ </informalexample>
+ </listitem>
+ <listitem>
+ <para>
+ This constructor allows you to customize the size limit and the value unit by using the
+ <code>limitSize</code>
+ and
+ <code>unit</code>
+ parameters respectively.
+
+ In JBoss Portal Platform, you can set the value unit to megabytes (MB), kilobytes (KB) or gigabytes (GB).
+ </para>
+ <informalexample>
+ <programlisting>
+public UIUploadInput(String name, String bindingExpression, int limitFile, int limitSize, UploadUnit unit)
+</programlisting>
+ </informalexample>
+ <para>The following is an example using the third form:</para>
+ <informalexample>
+ <programlisting language="Java">
+PortletRequestContext pcontext = (PortletRequestContext)WebuiRequestContext.getCurrentInstance();
+PortletPreferences portletPref = pcontext.getRequest().getPreferences();
+int limitFile = Integer.parseInt(portletPref.getValue("uploadFileLimit", "1").trim());
+int limitSize = Integer.parseInt(portletPref.getValue("uploadFileSizeLimit", "").trim());
+UploadUnit limitUnit = UploadUnit.valueOf(portletPref.getValue("uploadFileLimitUnit", "MB").trim());
+UIUploadInput uiInput = new UIUploadInput("upload", "upload", limitFile, limitSize, limitUnit);
+</programlisting>
+ </informalexample>
+ </listitem>
+ </itemizedlist>
+ </listitem>
+ <listitem>
+ <para>
+ Obtain the limit from the
+ <code>XML</code>
+ configuration by adding the following code to either
+ <code>portlet.xml</code>
+ or
+ <code>portlet-preferences.xml</code>
+ :
+ </para>
+ <informalexample>
+ <programlisting language="XML">
+<! The number of files are uploaded -->
+ <preference>
+ <name>uploadFileLimit</name>
+ <value>3</value>
+ <read-only>false</read-only>

+ <name>uploadFileSizeLimit</name>
+ <value>300</value>

+<! The unit limit -->
+ <preference>
+ <name>uploadFileLimitUnit</name>
+ <value>KB</value>
+ <read-only>false</read-only>
+ </preference>
+</programlisting>
+ </informalexample>
+ <note>
+ <para>
+ The
+ <code>0</code>
+ value means the upload size is unlimited, and the value unit is set to megabytes.
+ </para>
+ </note>
+ </listitem>
+ <listitem>
+ <para>
+ Use the
+ <code>getUploadDataAsStream()</code>
+ method to get the uploaded data:
+ </para>
+ <informalexample>
+ <programlisting language="Java">
+UIUploadInput input = (UIUploadInput)uiForm.getUIInput("upload");
+InputStream[] inputStreams = input.getUploadDataAsStreams();
+...
+</programlisting>
+ </informalexample>
+ <para>The upload service stores a temporary file on the file system during the upload process. When the upload is finished, the service must be cleaned to:</para>
+ <itemizedlist>
+ <listitem>
+ <para>Delete the temporary file.</para>
+ </listitem>
+ <listitem>
+ <para>Delete the classes used for the upload.</para>
+ </listitem>
+ </itemizedlist>
+ </listitem>
+ <listitem>
+ <para>
+ Use the
+ <code>removeUploadResource(String uploadId)</code>
+ method defined in the upload service to purge the file:
+ </para>
+ <informalexample>
+ <programlisting language="Java">
+UploadService uploadService = uiForm.getApplicationComponent(UploadService.class);
+UIUploadInput uiChild = uiForm.getChild(UIFormUploadInput.class);
+for(String uploadId : uiChild.getUploadIds()) {
+ uploadService.removeUpload(uploadId);
+}
+</programlisting>
+ </informalexample>
+ <note>
+ <para>
+ Ensure the file is saved
+ <emphasis role="italics">before</emphasis>
+ the service is cleaned.
+ </para>
