[b]java.lang.OutOfMemoryError.......PLEASE HELP A.S.A.P.!!!!!![/b]
I am currently writing code for a database software using Joins, Collections, Vectors, etc. and when running the code I keep getting a java.lang.OutOfMemoryError. The thing is that I have a parser that parses through different XML files and Java files. It seems as though some of my collections need more space or something else doesn't have enough memory for the parser to pick up everything. It only happens after I add a new constrainable or selectable to the XML file and try and run Queries with that (at least that is where I think the problem is). At this point I have no clue as to what is going on. Could someone please help me out.
Thanks in Advance!This is touching on the obvious but can you refer to your logs and find out where your program is running out of memory. I have a sneaky suspcion your're in a loop with an condition gone horribly wrong.
Based on your system specs, your collections should be able to handle your data. -

Please help with my helper class
Hi,
plz I need some assistance with this:
I have a big table which consist of 200 columns. This table gets fields from different tables. It has records of orders which may have several items and each item can have up to 8 taxes. So i have fields reaping for other order order records. I need to display an order then have a navigation to list items in details, with all its taxes, one by one.
Here is how I have decided to do it in a nutshell. I have decided to get all taxes of a particular item and put in a map with tax_codes as values and tax details arraylist as values. I then add this to an item with its other details. then I add items to a particular order. I have separated orders,items and taxes in their separate beans. Im trying to first the implimentation for each order, item and taxes by displaying them on a JSP. However am currently getting the following error with taxdetails:
java.lang.ClassCastException: OrderItems.ItemTax cannot be cast to java.lang.String

sometimes a tap on the head is needed to really learn and understand :-)You're casting them to the String type while they are of the ItemTax type and you've confirmed it yourself. Likely you misunderstood the concepts behind "casting" and you was expecting some magic that they are automatically converted somehow from the ItemTax type to the String type while the ItemTax class isn't a subclass of the String class :) -
Please Help::How to display a Map with LIsts as Keys and Values using JSTL
Hi,
I need some assistance on how to display a Map in JSP using struts or core JSTL. I have a HashMap which has a List of keys and each key maps to a value of an ArrayList.i.e I have an ArrayList of taxCodes and each taxCode maps to a value of taxDetails which is an ArrayList of details for for that particular taxCode. I have some trouble to display each taxCode then display taxDetails for each taxCode. Here is my code below:
OrderDetails.java

Rendering an error-display - Please help!!
Hi everyone,
I'm about to give up. I use the Orion 1.5.2 appserver for EJB, JSP and servlets. It works great and is the best appserver i've tried so far. Except for one thing:
As it seems, Orion doesn't have a custom error-page. When I invoke 'response.sendError(...)', Internet Explorer receives the status-code and displays its own error-page ("this site could not be reached"). Netscape displays some similiar page, showing the status-code and the attached message. But I want to show a custom error-page, that show more information about the message, and looks good as well. How can I accomplish that? I've looked through the forum and browsed through the documentation of Orion... nothing...
Ohh, and one more thing... Does anyone know how to make orion use another database than HSQL for EJB's? I want to use MySQL with the MySQL J/Connector.
Please help me!
NilleFinally!!!
Thank you very much.
Would it be possible to accomplish something like this:
<error-page>
<error-code>*</error-code>
<location>/error.jsp</location>
</error-page>and the corresponding JSP:
<%
int errorCode = ((Integer)request.getParameter("status-code");
String message = (String)request.getParameter("message");
%>
<HTML>
<HEAD>
<TITLE>Error <%= errorCode %></TITLE>
</HEAD>
<BODY>
Status-code: <%= errorCode %><br>
Cause: <%= message %>
</BODY>
</HTML>So that I have a generic error-page that renders all sendError invokations, and can fetch the status-code and the attached message.
If a ServletException occures and I have a page that handles this exception, can I reach the exception from the error-page? Something like request.getAttribute("exception"), or something like that.
Thank you alot for answering!

WAR cookie example not working. Please help!
Hi,
The cookie example worked fine if I put everything unpackaged under the
public_html/cookie directory. However, when I jarred this directory as
cookie.war and registered it with WLS, I got this exception when trying
to access CookieCounter servlet.
javax.servlet.ServletException: Servlet class: servlets.CookieCounter
could not
be loaded - the requested class wasn't found in the classpath
Also, I was able to get to the hello.html page (my welcome-file) when I
put in this request
http://127.0.0.1:7001/cookie
That means the server was able to extract the cookie.war file and parse
web.xml correctly.
The structure of my cookie.war file is exactly the same as the cookie
directory's.
This is what my cookie.war file looks like
error.jsp
WEB-INF/classes/servlets/CookieCounter.class
WEB-INF/classes/CookieCounter.class
WEB-INF/CookieCounter.java
WEB-INF/web.xml
images/cookie.jpg
hello.html
This is the entry in weblogic.properties
weblogic.httpd.webApp.cookie=c:/weblogic/myserver/public_html/cookie.war
my web.xml is
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application
1.2//EN" "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app>
<!--
<context-param>
<param-name>weblogic.servlet.reloadCheckSecs</param-name>
<param-value>0</param-value>
</context-param>
-->
<servlet>
<servlet-name>CookieCounter</servlet-name>
<servlet-class>servlets.CookieCounter</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>CookieCounter</servlet-name>
<url-pattern>monster</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>hello.html</welcome-file>
</welcome-file-list>
<error-page>
<error-code>404</error-code>
<location>/error.jsp</location>
</error-page>
</web-app>
The problem seems to be that weblogic was able to find
CookieCounter.class under the unpackaged cookie directory but not inside
cookie.war
Please help.
Thanks a lot.
By the way, if you have a war file that works, please send it to me at
[email protected]
I would greatly appreciate it.
Try resetting it:
Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
Next try restoring via itunes. -

if you contact me than I can send the code to you.
Thank you in advance. -
