java.util.Date / string issue in JSP file

damo.gets · 08-28-2008, 09:17 PM

My texts for JSP/JSTL do not get here until probably Monday, but this is the only project that I've got going on right now. I have a value, currently held in a string, that I need to parse into the standard java.util.Date elements (ie x.date, x.year, x.month, x.hours, x.minutes, x.seconds). The sun documentation is showing me some things that might be useful, but 90% of it is depreciated.

Can someone tell me a quick and simple way to take a string value of the fomatting: "2008-07-11 15:30:00.0" and break it down into a java.util.Date element x with the previously mentioned attributes?

We've got java.util.Date beans defined in this code, but until my documentation gets here (hopefully tomorrow and not Monday), I really don't know how to make any of the beans do what I want with this string.

Anything you can enlighten me on in this situation would be very much appreciated.

TIA

Also, sorry for the multiple posts on my topic, but I've got a little bit more information that may be helpful to show you guys exactly where I'm at right now.

Okay so here's a cut 'n paste of text from a BBS where I was looking for some help with this... It explains a little more thoroughly what I've tried to do to get this working, as well as the point that I don't know nearly enough about JSP/Java interaction yet.

Instantiate a DateFormat object df, then myDate = df.parse(myString)?

Sry, I know that's on the page. 's all I got.

Well after including java.text.Dateformat the following code is not
working
from within the jsp:

Code:

                           <%
                                 inDate = java.text.DateFormat.parse(param.timeIn);
                                 outDate = java.text.DateFormat.parse(param.timeOut);
                            %>

*feels eyelids grow heavy*

Okay my guess at this point is that I have to use a

Code:

<jsp:useBean id="ouah" class="java.text.DateFormat" scope="page" />

to instantiate DateFormat into something that I can use... then it will probably be some sort of

Code:

<jsp:setProperty name="ouah" property=??? value=???>

to invoke the formatting on my string... I don't really have a clue what goes in property, but I can probably find that in the class methods... Now that I think about it it should be "parse" I would assume, and value should have my "${whatever}" holding the string that I want to format.

I do not have a clue if I'm right, though. And if I'm right I don't have a clue on how to access the results unless they'd be ouah.hours, .minutes, etc...

java.text.DateFormat is completely unknown to my tomcat6
java.text.SimpleDateFormat is found, and seems alright until it tries to execute the block of code that my parse testing is in.

tomcat logs vomit this:
ug 28, 2008 4:08:16 PM org.apache.catalina.core.ApplicationDispatcher invoke
SEVERE: Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException: Cannot find any information on property 'parse' in a bean of type 'java.text.SimpleDateFormat'

from my code of:

Code:

<jsp:useBean id="fmtDate" class="java.text.SimpleDateFormat" scope="page" />
. . . .
<%-- debugging --%>
<jsp:setProperty name="fmtDate" property="parse" value="$ (param.timeIn}" />
<%-- done debugging --%>

Hope this gives more of a clue of where I'm at...

TIA for any advice you can give or pointers in the right direction.
