How Do I Specify uri in JSP taglib Directive to Point to the Jar File

I put the trail-taglib-0.2.jar file in the MyApplication/WEB-INF/lib directory.
Because the .tld is included in the trail-taglib-0.2.jar, I added the following In the MyApplication/WEB-INF/web.xml file:
< filter >
< filter-name > trailFilter < /filter-name >
< filter-class > org.osjava.taglib.trail.OriginalRequestFilter < /filter-class >
< /filter >
< filter-mapping >
< filter-name > trailFilter < /filter-name >
< url-pattern > *.do < url-pattern >
< filter-mapping > How do I specify the uri in my JSP @taglib to point to the jar file? I think I did not get the path right:
< %@ taglib prefix="trail" uri="trail-taglib-0.2" % >

Your advices have been very good. Problems get solved one at a time.
1. Now, the taglib.tld in the WEB-INF directory can be found; however, another problem occurred: XML parsing error on file /WEB-INF/taglib.tld: (line 11, col 17): Element type "display-name" must be declared.
2. no matter where I insert the filter and its mapping in the web.xml file,
<filter>
   <filter-name>trailFilter</filter-name>
   <filter-class>org.osjava.taglib.trail.OriginalRequestFilter</filter-class>
</filter>
<filter-mapping>
   <filter-name>trailFilter</filter-name>
   <url-pattern>*.do</url-pattern>
</filter-mapping>The server cannot find the Struts tag libraries. If I remove the filter tag and its mapping, the server does not complain anymore. I checked the DTD, the filter tag and its mapping tag should be before the servlet tag and servlet mapping tag. But, it does not work.
Here is the taglib.tld:

How to call class file from jsp without creating packages

i m using tomcat 5.5
i stored my class file into WEB-INF\Class directory
how to call that class file. from my jsp page.
i got some error.
i used package concept,that works fine.Then use packages.
As of Java1.4, you can no longer import classes from the default package (no package declared) into classes that are packaged.
All Tomcat classes are in packages, including the compiled JSP.
Therefore: Your classes need to be in a package inorder to be imported and used by the JSP.
Why the problem? If you know it works with packages, why try not to use them?

How to send information from HTML page to JSP without reloading HTML page?

Hello,
Is it possible to send information(row number selected by user) from HTML page to JSP without reloading HTML page?
Thanks.
Oleg.

Yes, you can do this with framesets and a hidden frame.
You need a bit of JavaScritp in the "visible" frame that
sets the location of the hidden frame to the JSP.
Add the user's choice as a parameter to the JSP URL.

In chrome I'm getting green double underline hyperlinks to ads. How can I get rid of this without adding more junk to the computer?

I have both safari and chrome, because I'm used to chrome. The only extension I have is Google docs. I started getting green double underline hyperlinks to ads. How can I get rid of this without adding more junk to the computer? People suggest programs to do it, but how do I know they won't make it worse?
Is someone from Apple here and can answer?
Thanks!

You may have installed the "VSearch" trojan. Remove it as follows.
Malware is always changing to get around the defenses against it. These instructions are valid as of now, as far as I know. They won't necessarily be valid in the future. Anyone finding this comment a few days or more after it was posted should look for more recent discussions or start a new one.
Back up all data before proceeding.
Step 1
From the Safari menu bar, select
          Safari ▹ Preferences... ▹ Extensions
Uninstall any extensions you don't know you need, including any that have the word "Spigot," "Trovi," or "Conduit" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
Reset the home page and default search engine in all the browsers, if it was changed.
Step 2
Triple-click anywhere in the line below on this page to select it:
/Library/LaunchAgents/com.vsearch.agent.plist
Right-click or control-click the line and select
          Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item named "com.vsearch.agent.plist" selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.
Repeat with each of these lines:
/Library/LaunchDaemons/com.vsearch.daemon.plist
/Library/LaunchDaemons/com.vsearch.helper.plist
Restart the computer and empty the Trash. Then delete the following items in the same way:
/Library/Application Support/VSearch
/System/Library/Frameworks/VSearch.framework
~/Library/Internet Plug-Ins/ConduitNPAPIPlugin.plugin
Some of these items may be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.
The problem may have started when you downloaded and ran an application called "MPlayerX." That's the name of a legitimate free movie player, but the name is also used fraudulently to distribute VSearch. If there is an item with that name in the Applications folder, delete it, and if you wish, replace it with the genuine article from mplayerx.org.
This trojan is often found on illegal websites that traffic in pirated content such as movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow.
You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the Internet criminal behind VSearch has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing has not done so, even though it's aware of the problem. This failure of oversight has compromised both Gatekeeper and the Developer ID program. You can't rely on Gatekeeper alone to protect you from harmful software.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

Thank you. I used to be able to Export from Quark to Acrobat without any problems when I was using Acrobat 7. Just changed to Acrobat 8 and have this problem. My 8.5x11 pages become 33x44 inches when exported to Acrobat 8. 400% increase in size. I don't know why. I tried Printing my Quark file to Adobe PDF and that worked. Thank you for your help.

As a student, you might be able to get Office for Mac from the college bookstore at a substantial discount. Otherwise, I think your best option for documents that need to be shared with Office users is to get one of the free Office clones such as LibreOffice.

How do I get rid of the new "status bar" at the bottom of the page where the web address pops up?

On the left hand side of the page in the bottom corner, the web address pops up every time a new page is loading. What if I don't want that? How do I disable it?

miss.bev.brown, Right-click on a toolbar, then click on teh "Add-on bar" entry to de-select it.
If the add-on bar keeps coming back, you will have an add-on that is causing this. One that does this is the McAfee Site Advisor, disabling or uninstalling it stops that from happening.

How do I save a PDF as an excel file when the PDF is horizontal. Adobe tries to rotate the page, but the data is entered in an horizontal format.

Thanks for the quick reply. I figured out how to get the desired results by using tagging. For anyone who may reference this post in the future, I went to "Customize" in the top right corner of Adobe, then selected "Create new tool set...", looked under "accessiblity and found the "tag" option. Hit ok, tag is added to the toolbar. Then I highlighted the dataset in the PDF that was relevant to the output format, then clicked "tag", saved as spreadsheet. Sorry I can't provide more details on how tagging works or if there's a more elegant solution available, but I'm sure one's out there.

Be precise.
It is not Pages '09 that is broken.

There are improvements, we shall see how useful, but in less than a minute I have already discovered bugs.

My emails are appearing along the top of the page in the tool bar area? how do i get rid of this and back to the regular email page

I opened my Mozilla yesterday and noticed my email page format was different then after a second, I noticed all my emails were now appearing along the top of the page in the tool bar area below "Fine Edit View Go ...etc" I'm not sure what happened. PLEASE help me I'm sure it's probably an easy fix, however I don't know how to fix it :)~ Also they are oldest email first, and since I normally save them for 45 days before deleting, I cant seem to get to the most recent email first. Ugh.
Truly appreciate your help.

This is what happens when you continually open messages in tabs but never close them. Pretty soon all you have are message tabs showing and you have pushed the Inbox off the screen.
Get in the habit of closing message tabs after you read them.
To get out of your situation now, right click one of the tabs and select Close Other Tabs. Then use the x to close the last one.
