Installation

A good starting point for JSP development is Hello World JSP.

ztemplates is a Filter.

Configuration

(since 1.0.0)

ztemplate scans the classpath at startup for annotated classes. If your application contains many jars this is time-consuming. You may wish to speed things up by providing a filter that only includes jars and classes you need.

Do it as follows to ensure that the default ztemplates classes are included.

The default implementation only scans WEB-INF/lib and WEB-INF/classes.

ZClassPathFilter has changed to ZIClassPathFilter, note the 'I'

If no filter can be found ztemplates prints a warning to the console, so check the console to see if the filter is used or not.

    <context-param>
      <param-name>ZIClassPathFilter</param-name>
      <param-value>com.mycompany.MyClassPathFilter</param-value>
      <description>
      	Restrict classpath scan to jars/classes known to contain ztemplates-relevant classes.
      	Best MyClassPathFilter extends ZDefaultClassPathFilter
      </description>
    </context-param>


public class MyClassPathFilter extends ZDefaultClassPathFilter

{

  @Override

  public boolean acceptClass(String name) throws Exception

  {    

    //include the default ztemplates classes

    if(super.acceptClass(name))

    {

      return true;

    }

    

    //include your own classes here

    return name.startsWith("com.mycompany");

  }

}

The default implementation only scans WEB-INF/lib and WEB-INF/classes. To add more locations override acceptClasspathPart.


public class MyClassPathFilter extends ZDefaultClassPathFilter

{

  @Override

  public boolean acceptClasspathPart(String name) throws Exception

  {    

    //include the defaults

    if(super.acceptClasspathPart(name))

    {

      return true;

    }

    

    //include your own classpath locations here

    return ...;

  }

}
