Constructor Detail

Method Detail

getTemplateClasspath

public abstract java.lang.String getTemplateClasspath()

Return path to Velocity template to render this tag

---

prepareContext

public abstract void prepareContext(org.apache.velocity.VelocityContext ctx)

Prepare context for execution

---

release

public void release()

Release any resources we might have acquired.

---

doStartTag

public int doStartTag(java.io.PrintWriter pw)
               throws javax.servlet.jsp.JspException

Evaluate any tags inside us. This will also allow us to have child tags send us messages.

Overrides:

doStartTag in class HybridTag

---

doEndTag

public int doEndTag(java.io.PrintWriter pw)
             throws javax.servlet.jsp.JspException

Check all all the public properties that must be set by now, either by tag arguments or tag children.

Overrides:

doEndTag in class HybridTag

---

doStandaloneTest

public java.lang.String doStandaloneTest(java.util.Map inMap)
                                  throws java.lang.Exception

---

getVelocityContext

private static org.apache.velocity.VelocityContext getVelocityContext()
                                                               throws java.lang.Exception

---

getVelocityClasspathResource

protected static java.lang.String getVelocityClasspathResource(java.lang.String inClasspathString)

Velocity wants classpath resources to not have a leading slash. This is contrary to how one would normally load a resource off the classpath (e.g. SampleTag.class.getResourceAsStream("/extag/resources/test.html")
