Cannot create a session after the response has been committed (Tomcat 6)
I'm getting a rather annoying error when I try to open a pretty basic JSP page.
I'm rather new to the whole JSP scene, so I'm following the example found on pages 287 and onwards in "JSF in Action - Manning" in case anyone wanted to check my code against the source.
I've searched for about 4 hours now, coming back to this site a couple of times, once reading about writeouts and stuff. But I'm not really sure this is the issue in this case and if it is, where exactly the problem lies.
I've already fixed a number of errors I got (jtsl.jar and standard.jar missing etc...) but this particular problem is driving me (and my co-workers for that matter :-) ) up the wall.
Anyone willing to help me out here?

When searching for this error, this was the first page google gave me. I found the answer and just in case anyone else stumbles in here with the same question I thought I'd share my findings.
Unfortunately, if your problem is the same as mine, you're going to feel pretty silly. I was navigating to the wrong page. If MyFaces(when running tomcat) tries to resolve to a page that doesn't exist, the error given above is what happens.
In my case I accidentally put my .jsp page into the wrong directory and ended up banging my head against the wall for an hour figuring that out. Hope this helps someone.

Error: WEB3010: Cannot create a session after the response has been committ
Hi,
I am seeking more information on that error. You know how to explain to me what she is, which the possible causes, if somebody already had some problem where that mistake happened.
Please, if somebody has some information he send me.
Thanks
DenisCommitting a response involves sending headers/data back to the client. When a web application session is created, the session ID needs to be sent back to the client. This is done either via a Set-Cookie header or is encoded in the URLs returned to the client. When response has been committed before the session is created, there is no way for the session ID to be sent back to the client, hence the error.
To correct the error, either increase the size of the output buffer or page buffer (if it is a JSP) or remove any calls that may be flushing data (thereby committing the response) to the client. -
Tiles- Cannot forward after response has been committed Error
I am trying to use following approach for my tiles implementation but i am getting error like
java.lang.IllegalStateException: Cannot forward after response has been committed.
I have gone thorugh the other posts regarding the same error but not helping me.
Any clues greatly appreciated.
Thanks,
Sachin
"I haven't found a way to directly dispatch to a tiles definition, but you can eliminate the need for multiple "wrapper" JSPs by creating a single "tilesDispatch" JSP that is able to dispatch to different tiles definitions, and establishing a convention for mapping URLs to that JSP, and identifying the tiles definition you want to load.
For example, you could use the following convention to identify a tiles definition:
/tiles/defName
where "defName" is the name of the tiles definition (from tiles.xml) that you want to use. The code for the tilesDispatch.jsp would be as follows:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="t" uri="http://jakarta.apache.org/struts/tags-tiles" %>
<%
String tilePath = request.getRequestURI();
int slashIndex = tilePath.lastIndexOf('/');
if (slashIndex >= 0) {
tilePath = tilePath.substring(slashIndex+1);
%>
<t:insert definition="<%=tilePath%>" flush="false"/>
The scriptlet code takes the request URL (e.g. /tiles/defName), strips off everything up to and including the final slash (e.g. defName), then the tiles "t:insert" tag is used to look up and insert the corresponding tiles definition.
In order to map all URLs of the form /tiles/* to the tilesDispatch.jsp, you would need to add the following to your web.xml:
<servlet>
<servlet-name>tilesDispatch</servlet-name>
<jsp-file>tilesDispatch.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>tilesDispatch</servlet-name>
<url-pattern>/tiles/*</url-pattern>
</servlet-mapping>
Note: You may need to insert a slash before tilesDispatch.jsp in the <jsp-file> element. I am using pre-compiled JSPs, so my configuration is a little different. So if <jsp-file>tilesDispatch.jsp</jsp-file> doesn't work, try <jsp-file>/tilesDispatch.jsp</jsp-file>.
Once you have this set up, you can refer to tiles definitions using the /tiles/defName convention in your faces-config.xml. For example, if you have two tiles definitions in your tiles.xml file: tile1 and tile2, you could have something like the following in faces-config.xml:
<navigation-rule>
<from-view-id>/tiles/tile1</from-view-id>
<navigation-case>
<from-outcome>success</from-outcome>
<to-view-id>/tiles/tile2</to-view-id>
</navigation-case>
</navigation-rule>
Note that when I have used this convention, I also have used the prefix mapping for JSF. That is, when linking to a JSF page, based on a tiles definition, from a non-JSF page, the URL would be as follows:
/faces/tiles/defName
In this case, the Faces servlet is initially invoked, which sets up the JSF environment. Then the /faces prefix is stripped off, and the remaining URL (/tiles/defName) is routed to the tilesDispatch.jsp, which strips off the /tiles/ prefix, and inserts the "defName" definition.
We are currently using this approach in a number of web apps, and it is working very reliably. I hope this helps.Hi gimbal2,

Creating a Materialized View Log After the Data has been instered
Hi,
I am trying to create a method of replication from Oracle to MySQL using the Materialized View Log table.
This has been done before and works quite well, the only problem is that I am trying to impliment the log after the table has been created and populated and wish to push all the existing data through the log file...
Does anyone know if it is possible to refresh the Materialized View Log and not a Materialized View.
The way the replication is intended to work is:
Oracle> Data inserted into table
Oracle> writes the vector data to the MVL
Script> Monitors the MVL and can see the changes being made to the Oracle Table
Script> Updates MySQL with the data and removes the rows from the MVL
MySQL is then used with other unix systems
Currently we export the data from the table using Triggers and a cronjob running every x minute to check for changes in the TriggerTables
Many thanks for your time on this, I have been checking for almost a whole working day and not found the answer to this problem.Thats what I thought, the MVL will only read data that has changed since it was created and wont have the option to load in all the data as though it was made before the table was created.
From what I have read, the MVL is quicker than a Trigger and I have some free code that prooved to work from a MVL using it as a reference to know what records to update. There is not that much to a MVL, a record ID and type of update, New, Update or Delete.
I think what I will have to do is work on a the same principle for the MVL but use a Trigger as this way we can do a full reload if required at any point.
Many thanks for your help. -
I am running safari 7.0.6 with IOS 10.9.4. after the mac has been asleep and I log on I cannot open safari as it appears to have crashed. the workaround to this is to reboot the IOS and log back in after which safari will open. Any ideas on how to resolve this?
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter the name of the crashed application or process. For example, if iTunes crashed, you would enter "iTunes" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Select the messages from the time of the last crash, if any. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
☞ The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ User Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of crash reports. The name of each report starts with the name of the process, and ends with ".crash". Select the most recent report related to the process in question. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a crash, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful. -
Is there a way to see what font was used originally, after the type has been converted to outlines?
Hi all, I would really like to know if there is any way to find out what font was used originally in an Illustrator document, after the type has been converted to outlines? The reason for this is I need to update some wording in a couple of old logos I had made and I have NO idea what font I had used...for the life of me I just cannot remember. Because this was so urgent for one of my projects I had to do a search online via "WhatTheFont" to see what font it could be (which I then didn't seem to have in my library!), and repurchase it. I am 99% sure I HAVE the font - or something VERY close - but under a different name.
Normally I keep a much better record of fonts used but there have been times occasionally in the past when I have done something in a hurry and changed the type to outlines without keeping the original, or keeping detailed notes at least. The fact that I did NOT keep notes on a few projects I have done in the past has made me want to kick myself because now I need to revisit one of those again..grrr:)
Can anyone offer any advice? I appreciate your help as always:)

Why does my Elements 12 ask me to enter Program Key after the product has been used and registered
I have had Elememts 12 for several months ... when I bought it ...I downloaded the program and registered it ... now ... every once in a while the program asks me to enter the Key number as if I never registered it ... also sometimes I get a message about my 30 day trial ...
I purchased Elements 12 not the Premier addition .... the disk Elements 12 comes with a trial version of Premier ... I did not install the 30 day trial version .... maybe t is Adobe trying to sell me the Premier addition ... I will pay more attention the next time the message comes up ... after reading some of the posts, I think that is what is happening ... I will have to wait ... someone wrote that they had the same problem and after a while, the message stopped appearing .... as I indicated .... I will look more carefully the next time I see the message...

I am trying to get through all your recent replies to go back to your post numbered 8.
1. Go to Control Panel/Programs and determine if you have Premiere Elements 12 and Photoshop Elements 12 installed.
2. When you have gotten the try out dialog, what program is mentioned in the dialogs - Premiere Elements 12 or Photoshop Elements 12?
3. The fundamental question is what did you purchase
a Photoshop Elements 12
b. Premiere Elements 12
c. Photoshop Elements 12 and Premiere Elements 12
From what you wrote it sounds like Photoshop Elements 12. Premiere Elements 12 seems to have come along as a tryout.
4. If Premiere Elements 12 is a tryout, after 30 days from first install of it, you should not be able to use it without a purchased serial number specific for Premiere Elements 12.
5. If you have no interest in Premiere Elements 12 tryout, uninstall it if it is installed. If it is not installed, then it is not the cause of your trial messages. But, I offer you this thought. Are these really License This Product/Continue Trial messages or are they really promotional dialogs (ads) put on your computer by Adobe who knows you have Photoshop Elements 12 and are trying to get you interested in Premiere Elements as well?
Please review and consider.
Thanks.

Add On...All my encountered with tryout pop ups have been as described and restricted to purchase Photoshop Elements 12 and Premiere Elements 12 purchased as bundle.

Why my home wifi connection ipad2 enter the password after the password has been wrong? Password is the phone able to connect after the connection is ipad2 has been an error?
Hello joe2616,
Thanks for using Apple Support Communities.
To troubleshoot this issue where your Wi-Fi network is dropping, please follow the directions outlined below.
Symptom: The network connection drops unexpectedly
Your Mac may not not stay connected to your Wi-Fi network reliably.
Your Mac may stop accessing the Internet during use.
Solution
Use these steps if your computer disconnects from its Wi-Fi network unexpectedly.
Check your range to the Wi-Fi router and reduce the effect of interference.
If your computer is too far from your Wi-Fi router or your environment has too much Wi-Fi interference, then your computer may not detect the Wi-Fi network properly. The easiest way to check for range limits with your Wi-Fi network is to move your computer or your Wi-Fi router closer together and make sure that there are no obstructions (such as walls, cabinets, and so forth) between the router and your computer.See Potential sources of wireless interference for more information about interference and solutions.
Try connecting to a different Wi-Fi network. If your computer works fine when connected to a different Wi-Fi network, then the issue may be related to your network router or ISP. In that case, contact the manufacturer of your router or your ISP.

Cannot save ... The file has been changed by another application.
Hi,
This is to report a wierd behavior when pages is auto saving documents.
An error pops up "Cannot save ... The file has been changed by another application."
Clicking "save anyways" seems to save the document OK, but still this is very anoying.
Saving the document manually (from the menu) isn't showing any error message.
Can someone help with a hint as of when this will be fixed or is there a workaround?
Thank you in advance,
Best Regards,
Michel.
Pages version 5.0.1 (1478) on OS X 10.9The phrase "by another application" makes it pretty clear that it is not Pages (or, in your case, Keynote).
What seems to be happening is that between the time that Pages opens a document, or saves it and the next time that it attempts to save it, something updates the document's file on the hard drive. Pages, recognizing that the file contains changes for which it is not responsible, presents this alert so you can decide whether you want to overwrite those changes. The usual suspects are backup and synchronization applications, like iCloud, which may not recognize the "Open" flag on the file, but I think it can also be triggered by AppleScripts, Automator workflows and Services, if they perform a "Save" action on the file. -
Where is the Document Number of a Journal after the Journal has been deleted in GL?
hi, guys,
can anyone tell me where is the Document Number going after the journal has been deleted in GL? can it be reused by another journal? or it is killed and dead in database?

EjwThey possibly still exist on the hard drive if you haven't overwritten that space already.
Your only hope is to try a file recovery program like Data Rescue 3 or some sort like that.
