As far as I can see, most of that code is redundant; removing all the
noise, this would be completely equivalent:
package com.axis.tag;
import java.util.Properties;
import com.axis.utils.PropertyLoader;
public class MyAnchorTag extends AnchorTag {
@Override
public int doStartTag() throws JspException {
Properties props =
PropertyLoader.loadPropertiesBundle("resources/permissionParameter");
String permission = props.getProperty("permission");
System.out.println(" Method :" + permission);
if(permission == null){
return super.doStartTag();
}
return SKIP_BODY;
}
}
And that doesn't seem to relate in any way to the question you're
asking. In particular, it doesn't use or access the href attribute in
any way, nor does it attempt to use the method Musachy mentioned.
So, what do you actually want to do, and how is it not working?
