Hi All,
I'm new to Custom Tags in JSP and I'm facing few issues.Can anyone
please help me out in this regard.
1) I have a custom tag like
<a:emp first="q">
Test
</a:emp>
Now when i include this custom tag in my jsp, the attribute is getting
set and the doStartTag is also getting called. The return variable in
the doStartTag is specified as EVAL_BODY_INCLUDE. Hence now the
doAfterBody is also getting executed and in this method I'm printing
some extra jsp contents and is working fine. But the problem I'm facing
is that Test given in the body of the jsp is also getting printed ,
which i dont want.Can anyone tell me how to stop Test from occuring in
the response stream but want to evaluate the body of the customtag,
which i want to use for formatting..
public int doStartTag() //throws IOException
{
try
{
this.pageContext.getOut().write("Hello world <br>");
}catch(Exception e){};
return this.EVAL_BODY_INCLUDE;
}
public int doAfterBody()
{
try
{
this.pageContext.getOut().write("<br> in do after body tag ");
BodyContent bc = this.getBodyContent();
}catch(Exception e){};
return this.EVAL_PAGE;
}
Output is
Hello wold
Test
in do after body tag
and out put i require is
Hello wold
in do after body tag
The reason being is I will be passing expression as the body and will
use this expression to modify the content of the body
2) Is it like if i call BodyContent bc = this.getBodyContent(); in
the doStartTag and later whatever i write to the out writer will not
come to response stream.
public int doStartTag() //throws IOException
{
try
{
this.pageContext.getOut().write("Hello world <br>");
BodyContent bc = this.getBodyContent();
this.pageContext.getOut().write("after getting body content
<br>");
}catch(Exception e){};
return this.EVAL_BODY_INCLUDE;
}
output is
Hello world
and what i want is
Hello world
after getting body content
Can anyone please give me some insight to this.
Thanks in advance for your time.
