    <p>I'm very new to using Velocity. I am trying to use it to generate an HTML form. I am working in Eclipse. The following jars are in my classpath:</p> <pre><code>velocity-dep-1.5.jar commons-collections.jar commons-lang.jar log4j-1.2.8.jar ant.jar </code></pre> <p>I am running an ant build file to build my project, but I don't see the HTML being generated. Is there something I'm missing in order to get it to actually generate the HTML file? The tutorial I was following only has two files that I based mine off of. It worked for the author, but perhaps there is something else that I don't realize being new to using velocity. I have included my code and build script to make it easier to see if I'm missing something. Thank you very much!</p> <p>I have the template code for my form here (<code>form.vm</code>):</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;title&gt; My Form &lt;/title&gt; &lt;/head&gt; &lt;body&gt; #if ($fieldErrors) #foreach ($error in $fieldErrors) $error&lt;br&gt; #end #end #if ($actionErrors) #foreach ($error in $actionErrors) $error&lt;br&gt; #end #end &lt;form name="edit" action="edit.action" method="post"&gt; &lt;table&gt; &lt;tr&gt;&lt;td&gt;Testing&lt;/td&gt;&lt;td&gt;123&lt;/td&gt;&lt;/tr&gt; #foreach($map in $radioList) #formRowRadio("method" $method "true" $selected)&lt;br/&gt; #end &lt;/table&gt; &lt;table&gt; #foreach($map in $textList) #formRowText($label $label $value) #end &lt;tr&gt;&lt;td&gt;&amp;nbsp;&lt;/td&gt;&lt;td&gt;&lt;input type="submit" name="submit" value="submit"&gt;&lt;/td&gt;&lt;/tr&gt; &lt;/table&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>Here is the java code I have to go along with that (<code>formDemo.java</code>)</p> <pre><code>import java.io.StringWriter; import java.util.ArrayList; import java.util.HashMap; import java.util.Map; import org.apache.velocity.VelocityContext; import org.apache.velocity.app.Velocity; import org.apache.velocity.Template; public class formDemo { public static void main ( String[] args ) throws Exception { Velocity.init(); ArrayList radioList = new ArrayList(); Map map = new HashMap(); map.put("method", "Yes"); map.put("selected", false); radioList.add(map); map = new HashMap(); map.put("method", "No"); map.put("selected", false); radioList.add(map); /* * add the list to a VelocityContext */ VelocityContext context = new VelocityContext(); context.put("radios", radioList); ArrayList textList = new ArrayList(); map = new HashMap(); map.put("label", "FirstName"); map.put("value", ""); textList.add(map); map = new HashMap(); map.put("label", "LastName"); map.put("value", ""); textList.add(map); context.put("textfields", textList); Template template = Velocity.getTemplate("form.vm"); StringWriter writer = new StringWriter(); template.merge(context, writer); } } </code></pre> <p>Build script (<code>build.xml</code>)</p> <pre><code>&lt;?xml version='1.0' encoding='UTF-8'?&gt; &lt;project name="velocityTemplate" default="jar" basedir="."&gt; &lt;property name='cls' location='${basedir}/classes'/&gt; &lt;property name='dat' location='${basedir}/data'/&gt; &lt;property name='gen' location='${basedir}/gen'/&gt; &lt;property name='lib' location='${basedir}/lib'/&gt; &lt;property name='src' location='${basedir}/src'/&gt; &lt;property name='tmp' location='${basedir}/templates'/&gt; &lt;path id='project.classpath'&gt; &lt;pathelement location='${cls}'/&gt; &lt;fileset dir='${lib}' includes='*.jar'/&gt; &lt;/path&gt; &lt;target name='clean' description='Clean.'&gt; &lt;delete dir='${cls}'/&gt; &lt;delete dir='${gen}'/&gt; &lt;/target&gt; &lt;target name='comp' description='Compile the source.'&gt; &lt;mkdir dir='${cls}'/&gt; &lt;javac srcdir='${src}' destdir='${cls}' classpathref='project.classpath' fork='true'/&gt; &lt;/target&gt; &lt;target name='jar' depends='comp' description='JAR the application.'&gt; &lt;jar destfile='${ant.project.name}.jar' update='false' filesonly='true' index='true'&gt; &lt;fileset dir='${cls}'/&gt; &lt;fileset dir='${src}'/&gt; &lt;/jar&gt; &lt;/target&gt; &lt;target name='run' depends='jar' description='Run the application.'&gt; &lt;path id='velocityTemplate.classpath'&gt; &lt;pathelement location='${ant.project.name}.jar'/&gt; &lt;fileset dir='${lib}' includes='*.jar'/&gt; &lt;/path&gt; &lt;taskdef classpathref='velocityTemplate.classpath'/&gt; &lt;mkdir dir='${gen}'/&gt; &lt;enumerator outputPath='${gen}' inputPath='${dat}' templateFile='${tmp}/form.vm'/&gt; &lt;/target&gt; &lt;target name='form' description='Creates form'&gt; &lt;path id='velocityTemplate.classpath'&gt; &lt;pathelement location='${basedir}/velocityTemplate.jar'/&gt; &lt;pathelement location='${lib}/velocity-dep-1.5.jar'/&gt; &lt;/path&gt; &lt;taskdef classpathref='velocityTemplate.classpath'/&gt; &lt;velocityTemplate outputPath='${basedir}/src' templateFile='${basedir}/form.vm'/&gt; &lt;/target&gt; &lt;/project&gt; </code></pre>

CO**Update:** I removed the target `<jar>` from my build script and modified the target `<run>` to just have `<java classname='my.classname.formDemo' classpathref='project.classpath fork='true'>` and everywhere I had `velocityTemplate.classpath`, I changed to `project.classpath`. additionally, I modified `Velocity.getTemplate()` in `formDemo.java` to contain the full path name to my template. Once I made these changes it worked. My HTML is messed up, but at least now it generates the HTML file. Note: I had been using a macro for the #formRowRadio and #formRowText, but I took that out too.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
