# How Do I: Enable the forkPreRenderTimeout Attribute?

The attribute forkPreRenderTimeout takes an integer value and sets the timeout value, in seconds, for the forked preRender phase. This attribute is applied only if forkPreRender=”true”. At this time, forkPreRenderTimeout is not supported by either the WebLogic Workshop interface or the WebLogic Portal Administration Portal, so you need to add the attribute manually to the .portlet file.

Timeouts for preRender forking can be enabled on these portlet types:

- JSP
- Page Flow
- JSR 168
- WSRP (Consumer portlets only)

At this time, forkPreRenderTimeout is not supported by either the WebLogic Workshop interface or the WebLogic Portal Administration Portal. Instead, you need to implement it at the code level in the .portlet file. This topic describes how to enable the forkPreRender attribute for each portlet type.

## JSP Portlet

To enable forkPreRenderTimeout on a JSP portlet:

1. Open the .portlet file for the specific portlet in any editor and locate the <netuix:javaPortlet> element.
2. Add the attribute forkPreRender=true within that element, as shown in the following code snippet:

    <?xml version="1.0" encoding="UTF-8"?>
       <portal:root xmlns:netuix="http://www.bea.com/servers/netuix/xsd/controls/netuix/1.0.0"
          xmlns:portal="http://www.bea.com/servers/netuix/xsd/portal/support/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/servers/netuix/xsd/portal/support/1.0.0
          portal-support-1_0_0.xsd">
          <netuix:portlet backingFile="com.bea.backing.jspBacking" definitionLabel="portlet_2"
             forkPreRender="true" forkRender="true" forkRenderTimeout="20" forkPreRenderTimeout="20" forkable="true"
             title="jspPortlet">
                <netuix:titlebar>
                   <netuix:maximize/>
                   <netuix:minimize/>
                </netuix:titlebar>
                <netuix:content>
                   <netuix:jspContent contentUri="/portlets/jspPortlets/jspPortlet.jsp"/>
                </netuix:content>
          </netuix:portlet>
       </portal:root>

## Page Flow Portlet

To enable forkPreRenderTimeout on a Page Flow portlet:

1. Open the .portlet file for the specific portlet in any editor and locate the <netuix:javaPortlet> element.
2. Add the attribute forkPreRender=true within that element, as shown in the following code snippet:

    <?xml version="1.0" encoding="UTF-8"?>
    <portal:root xmlns:netuix="http://www.bea.com/servers/netuix/xsd/controls/netuix/1.0.0"
       xmlns:portal="http://www.bea.com/servers/netuix/xsd/portal/support/1.0.0"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/servers/netuix/xsd/portal/support/1.0.0
       portal-support-1_0_0.xsd">
       <netuix:portlet backingFile="com.bea.backing.pfBacking" definitionLabel="portlet_1"
          forkPreRender="true" forkRender="true" forkRenderTimeout="20" forkPreRenderTimeout="30" forkable="true"
          title="PfTest1Controller">
             <netuix:titlebar>
                <netuix:maximize/>
                <netuix:minimize/>
             </netuix:titlebar>
             <netuix:content>
                <netuix:pageflowContent contentUri="/portlets/pfPortlets/pfTest1/pfTest1/PfTest1Controller.jpf"/>
             </netuix:content>
       </netuix:portlet>
    </portal:root>

## JSR 168

To enable forkPreRenderTimeout on a JSR168 portlet:

1. Open the .portlet file for the specific portlet in any editor and locate the <netuix:javaPortlet> element.
2. Add the attribute forkPreRender=true within that element, as shown in the following code snippet:

    <?xml version="1.0" encoding="UTF-8"?>
       <portal:root xmlns:netuix="http://www.bea.com/servers/netuix/xsd/controls/netuix/1.0.0"
          xmlns:portal="http://www.bea.com/servers/netuix/xsd/portal/support/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/servers/netuix/xsd/portal/support/1.0.0
          portal-support-1_0_0.xsd">
       <netuix:javaPortlet backingFile="com.bea.backing.javaBacking" definitionLabel="javaPortlet_1"
          forkPreRender="true" forkPreRenderTimeout="30" forkRender="false" forkRenderTimeout="20"
          forkable="true" title="Java Portlet"/>
    </portal:root>

## WSRP Consumer Portlet

To enable forkPreRenderTimeout on a WSRP Consumer portlet:

1. Open the .portlet file for the specific portlet in any editor and locate the <netuix:javaPortlet> element.
2. Add the attribute forkPreRender=true within that element, as shown in the following code snippet:

    <?xml version="1.0" encoding="UTF-8"?>
       <portal:root xmlns:netuix="http://www.bea.com/servers/netuix/xsd/controls/netuix/1.0.0"
          xmlns:portal="http://www.bea.com/servers/netuix/xsd/portal/support/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/servers/netuix/xsd/portal/support/1.0.0    portal-support-1_0_0.xsd">
          <netuix:proxyPortlet backingFile="com.bea.backing.wsrpConsumerBacking" cacheExpires="300"
             definitionLabel="portlet_1_1" description="" doesUrlTemplateProcessing="true"
             forkPreRender="true" forkPreRenderTimeout="20" forkRender="true" forkRenderTimeout="20"
             forkable="true" groupId="producerWA" portletHandle="portlet_1" producerHandle="wsrpProducer"
