Your problem is in your tag declaration:
<body-content>tagdependent</body-content>
You're specifiyng that your tag contains only text. Change it to:
<body-content>scriptless</body-content>
to allow other tags to be parsed.
Question
I have made a custom tag, to verify some user session state. But, <c:url>
is not working in my custom tag body. JSP:
<a href="<c:url value="/user/logout/"/>">Logout</a> <!-- THIS IS OK! -->
<bs:ifaccount logged="true">
<-- THIS JUST FLUSHES <C:URL VALUE=... TO WEB BROWSER -->
<a href="<c:url value="/user/logout/"/>">Logout</a>
</bs:ifaccount>
Tag declaration:
<tag>
<name>ifaccount</name>
<tag-class>bs.tags.IfLoggedTagHandler</tag-class>
<body-content>tagdependent</body-content>
<attribute>
<name>logged</name>
<type>java.lang.Boolean</type>
<required>true</required>
</attribute>
</tag>
Tag is implemented with SimpleTagSupport & getJspContent().invoke(null)
