<div class="jive-rendered-content"><p><span>Hi, the jbpm web designer can generate task forms for you (see more on this here: and here: </span><a class="jive-link-external-small" href="http://blog.athico.com/2011/07/develop-complex-jbpm-processes-all-in.html" target="_blank">http://blog.athico.com/2011/07/develop-complex-jbpm-processes-all-in.html</a><span>). These task forms (the process task form and a task form for each usertask in your process) are fully executeable and are stored in Guvnor, so you can modify them if needed. </span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>To answer your question, lets say you have a simple process:</p><p><a href="http://i.imgur.com/ZJLLo.png"><span> http://i.imgur.com/ZJLLo.png </span></a> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>where you define two process variables, x and y of type string, if you generate the process forms and view the sources, you will see that to print out</p><p>the value of x and y you could do for example:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>  </p><pre class="jive-pre"><code class="jive-code jive-xml"><span class="jive-xml-tag"><div class="div_checkbox"></span>
   ${x}
<span class="jive-xml-tag"></div></span>
<span class="jive-xml-tag"><div class="div_checkbox"></span>
   ${y}
<span class="jive-xml-tag"></div></span>
</code></pre><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>and if you users to enter in a value of specific process variable or output mapping of your user task you can do for example:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><pre class="jive-pre"><code class="jive-code jive-xml"><span class="jive-xml-tag"><form action="complete" method="POST" enctype="multipart/form-data" onsubmit="return taskFormValidator()"></span>
   <span class="jive-xml-tag"><div class="div_texbox"></span>
      <span class="jive-xml-tag"><input name="x" type="text" class="textbox" id="x" value="" /></span>
   <span class="jive-xml-tag"></div></span>
                           
   <span class="jive-xml-tag"><label for="name"></span>y<span class="jive-xml-tag"></label></span>
   <span class="jive-xml-tag"><div class="div_texbox"></span>
      <span class="jive-xml-tag"><input name="y" type="text" class="textbox" id="y" value="" /></span>
   <span class="jive-xml-tag"></div></span>
                           
   <span class="jive-xml-tag"><div class="button_div"></span>
      <span class="jive-xml-tag"><input name="Submit" type="submit" value="Submit" class="buttons" /></span>
   <span class="jive-xml-tag"></div></span>
<span class="jive-xml-tag"></form></span>
</code></pre><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>the JavaScipt, CSS and markup are not really needed, that's just something designer adds for the look/feel.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Hope this helps.</p></div>
