It looks like laboratory:laboratory actionPerformed has been defined such that it does
not allow <%= %> as an attribute value.
Check the tld for the taglib if true for this tag then what
you did should work, if false then it'll only take a
straight string:
actionPerformed="didThis"

Althought it doesn't look it, this needs a Tag Extra Info (TEI) stuff
included. A tag can't use request time variables unless TEI is used.
Here is the tutorial for this:

To get around this, just use the actual value for
LaboratoryTag.ADD_LABORATORY.
I'm using in my pages taglibs which get parameters during invoking them
on JSP page like:
and during parsing I get error:

Error parsing JSP page /webcomp/admin/add_laboratory.jsp
<%=LaboratoryTag.ADD_LABORATORY%> is a request-time attribute (invalid

That would be the place to start.
Unlike C/C++ where the keyword "static" denotes a private variable, a
static variable in Java is shared among all instances of the class.
This includes instances of subclasses.
So if one instance of a class changes the value of a static variable,

1. A DAO is used to do BMP, and is a regular Java class.
Instead coding JDBC calls directly in your EJB (find, create, store,
remove), you put them in a DAO which you call from your EJB.
2. A DAO can contain multiple SQL statements, including various SELECT,
INSERT, UPDATE, DELETE.

Looks like what you really need is to make these methods static and not
bother with object instance at all.

Following scenario is what I need, but I'll be hapy
to hear more about pooling.
I only know one reason for pooling. It is decreasing

I have class providing some methods. Metho
