passing variable to actionLink

[RidgewayM]

Hi All,
I'm new to JSP. Can anyone tell me how to pass the dirname variable below into the actionLink tag?

<% String dirname="google.com";%>

<a:actionLink href="

http://www."

+ <%= dirname %> target="new" value="click Here" />

Thanks in advance for any help

<a:actionLink href="[URL unfurl="true"]http://www.<%=[/URL] dirname %>" target="new" value="click Here" />

Cheers,
Dian

Thanks for your reply, Dian.

I tried your suggestion but all I get is

http://www.<%=

dirname%> in the hyperlink. ActionLink is a custom tag that obviously behaves differently than expected. I'm going to try and use <c:set>

Argh, didn't notice the actionLink thingie. With JSTL would be something like

<c:set var="dirname" value="[URL unfurl="true"]www.google.es">[/URL]
<a:actionLink href="[URL unfurl="true"]http://${dirname}"[/URL] target="new" value="click Here" />

Cheers,

thanks for your help, Dian, but it looks like I'll have to abandon the actionLink idea and go back to straight html in the jsp page. When I put the ${dirname} in the actionLink as you suggested, I get

http://${dirname}

in the hyperlink on the page.

Thanks again.

What about a # instead of $?

<c:set var="dirname" value="[URL unfurl="true"]http://www.google.es">[/URL]
<a:actionLink href="#{dirname}" target="new" value="click Here" />

Hi Dian,
I tried your suggestion

for:
<a:actionLink href="#{dirname}" target="new" value="click Here" />

the page returns the alfresco login url

for:

<a:actionLink href="

http://#{dirname}"

target="new" value="click Here" />

the page returns

http:///

Looks to me like actionLinks do not handle dynamic variables

Well, at least it looks like the variable is being recognized, despite of the lack of value. The difference between # and $ has to do with when the it's rendered, as shown here

Maybe it's worth to try a scope change, as shown here with something like

<c:set var="dirname" value="[URL unfurl="true"]http://www.google.es"[/URL] scope="session">
<a:actionLink href="#{dirname}" target="new" value="click Here" />

Cheers,
Dian
