using tag
I am using struts 1.1
I using logic equal tag to check whether a page context attribute value equals to some value .
here is my code
<bean:define id="test" value="0"/>
<logic:equal name="test" value="0">
<bean:define id="test1" value="2" />
</logic:equal>
<logic:equal name="test" value="1">
<bean:define id="test1" value="3" />
</logic:equal>
So only one logic equal will be true but not both . But when I call this jsp in the browser I get
jsp exception
OracleJSP: oracle.jsp.parse.JspParseException: Line # 220,
<bean:define id="test1" value="3" />
Error: Tag attempted to define a bean which already exists: test1
Why should I get this error when only one condition is true?
Thanks & Regards

To understand why this is a problem, look at the source of the Java
servlet that's generated. Remember that the JSP is translated statically
into Java, and then the resulting Java is compiled and run.
Try this instead:
<bean:define id="test1">
<logic:equal name="test" value="0">2</logic:equal>
<logic:equal name="test" value="1">3</logic:equal>
</bean:define>

Well, if I have a problem I usually remove all the stuff that works so I can
isolate the problem.
That way you would have only the code you posted in the JSP (the error would
not be at line 220) so you could post the whole JSP.
And then we could see if you defined the logic taglib at the beginning of
the file as you defined the bean.
This is just a wild guess of course (because we just see a small piece of
the code), but maybe if the <logic> taglibs are not defined then they become
just html code so the bean test1 ends up in being defined twice.
By the way I love this guessing game :-D, please tell me if this was the
problem...

What about the very first line of your code?
