Am I doing this JSP custom tags right ?...

Hi, I am new to JSP Custom Tags and I'd like to know if I am using it correctly. I'd like to converting code#1 into code#2 (code provided below for reference) using JSP custom tags, am I doing it correctly or is there a better way?

Any suggestions or tips would be greatly appreciated!

Thanks, noijet
***** code#1 (Inside a jsp)*****
<%
if(loginBean.isDualLogin()) {
%>

...Some HTML code....

else{
%>
...Some other HTML code....
<%
}
%>

***** code#2 (Inside a jsp) *** Is this correct ? *****
<control:conditional condition="user.isAdmin">
      ...Some HTML code....
</control:conditional>
<control:conditional condition="<%=(!user.isAdmin)%>">
      ...Some other HTML code....
</control:conditional>

***** Java tag handler *****
public int doStartTag() throws JspException {
if(condition) {
return EVAL_BODY_INCLUDE;
}
return SKIP_BODY;
}

Hi jessegivy, thanks for your post, I am new to JSP custom tags, so currently I am practicing with it. This kind of long, thanks in advance for your patience. Basically, from the start, we only had the if statement (code#1) --> then we used a conditional custom tag (code#2) to replace the 'if' statement --> Now, we want to add an else clause (code#1)--> This is why I am trying to use code#2, but I'm just wondering if thats the way it is usually done in JSP custom tag code.

I think:
EVAL_BODY_INCLUDE: Means to evaluate the body
SKIP_BODY: Means to 'done', skip body evaluation.

Thanks so much,
noijet.

Thank you searlas. So if I had to include that else condition to that "if" custom tag already existing, I would do it the way I stated above(code#2)?

Thanks so much,
