how to set hidden field value to a session attribute ?
hi friends!!
im new to struts and im developing a web application using struts and jsp.
in one scenario,i want to set the value of a string variable of a formbean to a session attribute through jsp.bcoz form bean is populated only when formdata is submitted,i wrote a hidden field in the jsp. i dont know how to set the value of a hidden field to a session attribute.
i wrote this in my jsp
<html:html>
<html:form>
<!-- some code for uploading here -->
<html:hidden property="albumId" value="<%= session.getAttribute("albId")"
%>
<html:submit>Upload Files</html:submit>
</html:form>
</html:html>
in a previous Action class, i set a session attribute to the string albId, and now, i want to send it to a form bean.
the jsp above returnd a compilation error.my appln server is apache tomcat 5.5.9
the error is like this
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 57 in the jsp file: /PicUploadForm.jsp
Generated servlet error:
The method setValue(String, Object) in the type TagSupport is not applicable for the arguments (Object)
please suggest how to send my session attribute value into the formbean.

It works on any container that supports JSP 2.0 (which
yours does).
If your container *doesn't* support JSP 2.0 you can
use the html-el tags.

JSP 2.0 is your friend (as is documentation).
