How do i include jsp code in tags? See example

Like the topic says; How do I include ordinary jsp code in tags? (In my case liferay tags, but it could as well be html-tags)

Example:

<liferay-ui:panel id="panel-c4" title="Service Bulletins" collapsible="true"
extended="<% if (noService==false) {
                  out.print("false");
                  }
               %>">
Test panel
</liferay-ui:panel>

In the example i just want to insert "false" so the expression looks like the following:

<liferay-ui:panel id="panel-c4" title="Service Bulletins" collapsible="true"
extended="false">
Test panel
</liferay-ui:panel>

This gives me a jasperException.. I´m used to PHP where this kind of code-includes are daily meat.

Can someone please point me in the right direction?

Thanks in advance!

You can have (I'm using ELs, as they are much cleaner):

  1. If variable noService is a boolean:

    <c:set var="isExtended"><%=noService ? "true" : "false" %></c:set>;

<liferay-ui:panel id="panel-c4" title="Service Bulletins" collapsible="true"
        extended="${isExtended}">
    Test panel
</liferay-ui:panel>

  2. If variable noService is a String:

    <c:set var="isExtended"><%="false".equals(noService) ? "false" : "true" %></c:set>

<liferay-ui:panel id="panel-c4" title="Service Bulletins" collapsible="true"
        extended="${isExtended}">
    Test panel
</liferay-ui:panel>

You can also do this.

<liferay-ui:panel id="panel-c4" title="Service Bulletins" collapsible="true"
extended="<%=String.valueOf(noService)%>">

<liferay-ui:panel id="panel-c4" title="Service Bulletins" collapsible="true"
    extended="${noService}">
    Test panel
</liferay-ui:panel>

noService must be set in request e.g.:

java:

...

    request.setAttribute("noService", false);
