Hello Guys,
I am having problems running my application via the Jbuilder in-built Tomcat. I have an XML parser jar file which contains class org.w3c.dom.Node
and when Jbuilder-Tomcat is run the Jar file (named parser.jar) get loaded as verified by my debug message.
I have even added the jar file to my classpath and path via control panel.
NOTE: Jar file resides in C:\<project-dir>\App-Root\Web-inf\lib\parser.jar.
And JBuilder 7 is configured to deploy the pplication from that location.
Please, help....
But, i keep getting the error below after logging into the application.
root cause
java.lang.NoClassDefFoundError: org/w3c/dom/Node
at org.apache.jasper.compiler.TldLocationsCache.processWebDotXml(
at org.apache.jasper.compiler.TldLocationsCache.init(

falls over.
Please, how do i escape single quote in a java.lang.String ....
Code will also be appreciated

Hello, i built a web site, with a navigation frame with some buttons.
Each buttons opens a frame on the right using :
<A class="contact" href="contactView.html" target="homePage">Contact</A></strong>
How do i make sure all users see the current version of each web page and not a browser cached version. Especially, after a page has been updated on the server.
Any code or reference will be appreciated.
I have Tomcat 4.1.27 and Apache 2.0installed and
working independently on a windows NTinstallation. I have followed
a web resources in attempt to install mod_jk
Success did not follow, but at least I am now getting error messages
in $CATALINA_HOME/logs/mod_jk.log

Of course Tomcat is started - but if it's listening on the right ports
or not is not clear to me.
Please Help

Hello, i am having problems Linking Apache and Tomcat with mod_jk. i can only request for JSPs in Tomcat via Apache
using the localhost and not actual machine name, after finishing my set up, using Apache 2.0 and Tomcat 4.1.E.g. http://localhost:8088/webAppRoot/jsp/xyz.jsp, if i use the actual host name say
http://U608st23:8088/webAppRoot/jsp/xyz.jsp, it falls over.Where
webAppRoot/jsp/xyz.jsp resides on Tomcat.
But,http://U608st23:8088 works on Apache as a standalone , loading the Apache home page.
Note: Listen U608st23:8088 was added to the httpd.conf.
In my server.xml i had:
<Listener className="org.apache.ajp.tomcat4.config.ApacheConfig"
append="true" />
Immediately following the <Server port="8005" ...> tag near the top of the file.

Then in <Tomcat-Home> /conf/jk/ has the following lines:
worker.list=ajp13, ajp14
Please, help!!!
Note: I could request for all JSPs on Tomcat via Apache using localhost, but not actual machine name.

Hello, i got this exception after running a query and populating JSP with result of query. The same screen works OK before. Are there practical/exact causes of this exception and definite ways of guiding against them. Because i am not flushing the output stream as far as i know.

Hello guys,
I am populating my Hashtable using numeric key from 1 to X, due to an inconsistent sequence in number. I need to display the records in order on screen and this is not possible 'cos the hashtable randomly arranges it's elements. So, is there a way of arranging the objects in a hasttable using it's numeric keys. All ideas are welcomed.

My original image of Jpeg format does not show on my web page, but after converting it to a .Gif image(using an image format converter) it shows. What do U think is responsible for this. Cheers.
Sorry, that was a typo

The image was referenced correctly. i have other images in the same webpage being displayed with a similar path.
