The problem you are facing is caused by the fact that you use double quotes
in both the enclosing tag and the enclosed tag. This way, the parser cannot
determine whether the seconde "-character it encounters matches the first to
close it, or opens a nested attribute value as you intend.
Try to use single quoting (') in your <bean:write > and enjoy the behaviour.
So :
<html:link href="ui.do?Param1=123&Param2=N&Param3=<bean:write name='ampp'
property='AMTRSD00.trDept'/>">
<bean:message key="myLinkText"/>
</html:link>
The bean:message tag is not nested, so there is no need to change this one.

True. That was the first thing I checked but the rtexprvalue is set to
"true" already and it doesn't make any difference:
<tag>
<name>link</name>
<attribute>
<name>href</name>
<required>false</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
Thanks again!

The spec says: rtexprvalue <=> scriptlets

I thought that you can use a custom tag as an attribute value for
another
tag, provided the attribute is designated within the TLD file as being
<rtexprvalue>true</rtexprvalue>.
