I want to be able to create a variable in a custom tag and make this
variable available in the JSP the tag was called from.
To do this I added the following line to the doStartTag (or doEndTag) method
in the custom tag.
pageContext.setAttribute("myvariable", myvariable,
PageContext.APPLICATION_SCOPE);
I then created a TagExtraInfo class that looked similar to the following
(this class was added to the tld file):
public class myTEI extends TagExtraInfo
{
public VariableInfo[] getVariableInfo(TagData data)
{
String name = data.getAttributeString("name");
String type = data.getAttributeString("type);
VariableInfo[] scriptvars = new VariableInfo[1];
scriptvars[0] = new
VariableInfo(name,type,true,VariableInfo.AT_BEGIN);
return scriptvars;
}
}
The problem with this is that in getVariableInfo the values of name and
type are null.
Can anyone tell me if the problem is with the line of code where I add the
variable to the pageContext or with the TEI class and how I can fix this?
Thanks,
Catharine
