Field Detail

classLoader

protected java.lang.ClassLoader classLoader
The class loader to use for instantiating application objects. If not specified, the context class loader, or the class loader used to load XMLParser itself, is used, based on the value of the useContextClassLoader variable.

useContextClassLoader

protected boolean useContextClassLoader
Do we want to use the Context ClassLoader when loading classes for instantiating new objects? Default is false.
Constructor Detail

NewTag

public NewTag()
Method Detail

setVar

public void setVar(java.lang.String var)
Sets the name of the variable exported by this tag

setClassName

public void setClassName(java.lang.String className)
Sets the class name of the object to instantiate

getClassLoader

public java.lang.ClassLoader getClassLoader()
Return the class loader to be used for instantiating application objects when required. This is determined based upon the following rules:

setClassLoader

public void setClassLoader(java.lang.ClassLoader classLoader)
Set the class loader to be used for instantiating application objects when required.
Parameters:
classLoader - The new class loader to use, or null to revert to the standard rules

getUseContextClassLoader

public boolean getUseContextClassLoader()
Return the boolean as to whether the context classloader should be used.

setUseContextClassLoader

public void setUseContextClassLoader(boolean use)
Determine whether to use the Context ClassLoader (the one found by calling Thread.currentThread().getContextClassLoader()) to resolve/load classes. If not using Context ClassLoader, then the class-loading defaults to using the calling-class' ClassLoader.
Parameters:
boolean - determines whether to use JellyContext ClassLoader.

doTag

public void doTag(XMLOutput output)
           throws java.lang.Exception
Description copied from interface: Tag
Evaluates this tag after all the tags properties have been initialized.
