h:outputLink with context path?
Hey,
give it anyway to set an flag in the <h:outputLink> tag to copy the context path automatic on the beginning of the value from outputLink or must I write my own component?
No flag like that... I'm not actually sure what the problem is here though. It definitely sounds like you don't need a custom component though!
What's wrong with just binding the value attribute to your backing bean, and let the bean figure out what your context root is?

After changing the context path, felix console, I can not checkout content via vlt.
Hi everyone,
I have the following issue. After changing the context path, via felix console, I can not checkout the content via vlt. Before that, I could checkout without any problems.
I am using CQ5.5, CRX2.3, context path: /Test
That is what I am trying:
vlt -v --credentials admin:admin co http://localhost:23310/Test/server/crx.default
Connecting via JCR remoting to http://localhost:23310/Test/server
[WARN ] Authentication required to access repository descriptors
[ERROR] checkout: com.day.jcr.vault.vlt.VltException: Unable to mount filesystem
caused by: javax.jcr.ItemNotFoundException: Not Found
caused by: org.apache.jackrabbit.webdav.DavException: Not Found
Other versions I tried:
vlt -v --credentials admin:admin co http://localhost:23310/crx
vlt --credentials admin:admin co http://localhost:23310/Test/server
vlt --credentials admin:admin co http://localhost:23310/Test
vlt --credentials admin:admin co http://localhost:23310/Test/crx
To verify if I could connect to the instance properly I started CRXDE
and try to connect to "http://localhost:23310/Test"
After click the ok button I got that error:

Get the context path with jspx
How can I get the context path using jspx?
with jsp I get using scriptlet
<%=request.getContextPath()%>but it didn't validate with xhtml
thanksI'm really unfamiliar with JSP Documents and I don't know if nesting the tags would be valid. Why don't you use EL in that case?
${pageContext.request.contextPath} will print out the value you need.
P.S. In case it just prints out as is without being evaluated, take a look at these:

Problem with absolute path and context using Tomcat 4
I added the following line to my server.xml:
<Context path="/track" docBase="track" />Now I have used absolute paths(ex: /includes/css/style.css) throughout my code and it worked when I served my application from the ROOT context but when I moved it to the /track - the paths did not include the new root context.
So instead of looking at http://localhost/track/includes/css/style.css it still looks at http://localhost/includes/css/style.css.
Is there any kind of setting I am missing in the web.xml or server.xml? I really would like to be able to use absolute paths relative to the context root.
Please help! Thanks in advance.
-ChrisHi,
I am not sure what exactly you are asking but here is my shot. If one tomcat is serving more than one application then the only way for tomcat to know which application to refer is by looking at the context path. Since you have the context path of /track then it should appear in all of your urls being directed to the server (for both servlet and jsp). Since you have used absolute path in all the cases either you will have to change the absolute path or you will have to define them relative (which is a better idea) to a base dir. Hope it helps.

I'm sure it has something to do with my directory structure, Were using a Tomcat server through Uni so i dont have access to change the context paths or anything like that. Any way to over come this problem would be so much appreciated! if your from Melbourne i'll buy u a beer ;o)
Thanks heaps.

SomethingStupidif you start javac in your directory
public_html>WEB_INF>classes>com
the compiler cannot find the the classes Product and ShoppingItem.
Start the compiler in public_html>WEB_INF>classes:
javac com/*.javaThe path
public_html/WEB_INF/classes
is in your case the classpath. javac uses the current working directory as default classpath. The classpath contains "root points" of package directory trees. -
Finding the context path or docBase in a backing bean - Howto
How should I go about finding the context path or docBase in a backing bean?
Is there anyway to get this from glassfish or jsf? GlassFish proudly displayed it on the Application Server > Applications > Web Applications > page. It puts it there with an EL for example:
${com.sun.aas.instanceRoot}/applications/j2ee-modules/jsf-witaCan and/or should I try to use it in a backing bean? i.e. can I rely on it to stay defined?
Or should I make a property which I can set for my backing work?Is this what you want?

TDASH 1,943,823 7,153 805 0
Objectives
To show that when serial scans are performed on database built on Solid State Disks (SSD) compared to Magnetic disks (HDD), the performance gain is far less compared to random reads with index scans on SSD compared to HDD
Approach
We want to read the first 100 rows of tdash table randomly into buffer, taking account of wait events and wait times generated. The idea is that on SSD the wait times will be better compared to HDD but not that much given the serial nature of table scans.
The code used
ALTER SESSION SET TRACEFILE_IDENTIFIER = 'test_with_tdash_ssdtester_noindex';
DECLARE
type array is table of tdash%ROWTYPE index by binary_integer;
l_data array;
l_rec tdash%rowtype;

In comparison with no direct path read, there are 1,218,651 db file scattered read waits with total wait time of 3,770 seconds. My understanding is that direct path read can use single or multi-block read into the PGA. However db file scattered reads do multi-block read into multiple discontinuous SGA buffers. So it is possible given the higher number of direct path waits that the optimizer cannot do multi-block reads (contigious buffers within PGA) and hence has to revert to single blocks reads which results in more calls and more waits?.
Appreciate any advise and apologies for being long winded.
Thanks,
MichHi Charles,
I am doing your tests for t1 table using my server.
Just to clarify my environment is:
I did the whole of this test on my server. My server has I7-980 HEX core processor with 24GB of RAM and 1 TB of HDD SATA II for test/scratch backup and archive. The operating system is RHES 5.2 64-bit installed on a 120GB OCZ Vertex 3 Series SATA III 2.5-inch Solid State Drive.
Oracle version installed was 11g Enterprise Edition Release 11.2.0.1.0 -64bit. The binaries were created on HDD. Oracle itself was configured with 16GB of SGA, of which 7.5GB was allocated to Variable Size and 8GB to Database Buffers.
For Oracle tablespaces including SYS, SYSTEM, SYSAUX, TEMPORARY, UNDO and redo logs, I used file systems on 240GB OCZ Vertex 3 Series SATA III 2.5-inch Solid State Drive. With 4K Random Read at 53,500 IOPS and 4K Random Write at 56,000 IOPS (manufacturer’s figures), this drive is probably one of the fastest commodity SSDs using NAND flash memory with Multi-Level Cell (MLC). Now my T1 table created as per your script and has the following rows and blocks (8k block size)
SELECT
NUM_ROWS,
BLOCKS
FROM
USER_TABLES
WHERE
TABLE_NAME='T1';
NUM_ROWS BLOCKS
12000000 178952which is pretty identical to yours.
Then I run the query as brelow
set timing on
ALTER SESSION SET TRACEFILE_IDENTIFIER = 'test_bed_T1';
ALTER SESSION SET EVENTS '10046 TRACE NAME CONTEXT FOREVER, LEVEL 8';
SELECT
COUNT(*)
FROM
T1
WHERE
RN=1;
which gives
COUNT(*)

Read aheads are like quasi logical I/Os and they will be cheaper compared to physical I/O. When there is large buffer cache and read aheads can be done then using buffer cache is a better choice than PGA?

Get context path in a jsp without using a scriptlet
Hi Guys
I am using Scriptlet to get a application context path in a JSP. I want to get the context path with out using an scriptlet in a JSP, is there way to achieve this..?
<%=request.getContextPath() %>/listofvalues.do?method=viewListOfValues thanks in advance.
Regards
Praveen
Edited by: praveen_kumarvr on Jul 3, 2008 8:30 AM${pageContext.request.contextPath}A common practice is to put this value in the <base href> in the HTML head and then use this as the root for all of the relative URL's in the page.

Request context path for portlet has wrong port number
I have a JSF application deployed as a portlet on the WLS_Portlet domain with port 8889. The portlet is being consumed in WebCenter Spaces, which lives in the WLS_Spaces domain with port 8888.
In my code, I am trying to get the request context path:
FacesContext.getCurrentInstance().getExternalContext().getRequestContextPath();
I expect this to return http://host:8889/contextroot (where I am able to access my app resources). Instead, it is returning http://host:8888/contextroot.
Any ideas why this is happening?

Hi
1. I am using WSAD 5.0
2. I have created a web project it has the following directory struture
Java Source
MyFile.java // This file needs to access the xml in MyData
Web Content
// MyData contains few xml and js files
MyData // POSITION 1
META-INF
WEB-INF
classes
lib
MyData // POSITION 2
MyShow.jsp
3. In the buildpath the source is set to Java Source
**Question 1: Which is the correct POSITION of the Folder 'MyData'?
1. Assuming the folder is placed in POSTION 1
Java file
-- What would be correct relative path access the xml file in MyData
(i tried ../Web Content/MyData/abc.xml,
./Web Content/MyData/abc.xml and
/Web Content/MyData/abc.xml but NOTHING worked)
<I know the ./ is for current directory and ../ is for parent one and / is for the root >
Jsp file
I am ABLE to access the javascript files with path /MyData/abc.js
2. Assuming the folder is placed in POSTION 2
Java file
-- I am ABLE to acces the xml file with the path /MyData/abc.xml
Jsp file
-- The file is NOT ABLE to access the path /WEB-INF/MyData/abc.js (WSAD automatically also creates the same path)
**Question 2: Depending on the position of folder how would i access MyData from JSP or Java file
-- One more important thing is that in WSAD 5.1 the folder created is 'WebContent' instead of 'Web Content' <without space>, Does it has any thing to do with it?
Any help would be highly appreciated, any links which would give my insight on this will also be of immense help
regards
Tarun DhillonI am not sure i understand your problem, however you need to arrange your directories so that they are in a logical order from the context root for your application
for Websphere Developer questions, you should probably try an websphere newsgroup as well. -
Multiple Context Paths Per Web Application
Hi,
We have a Web Application which has a Context Path of "titanadmin". We have some
HTML pages which refer to this within the URLs they contain. We need to move the
functionality in this Web Application to another Web Application with a Context
Path of "gp3admin". We cannot change the URLs in the generated HTML.
So, is it possible for a Web Application to have multiple Context Paths, so that
URLs starting with "/titanadmin/" and "/gp3admin/" both go to the same Web Application.
Thanks,
DaveThere is no hard limit to the number of Web Applications (I managed a WSSv3 farm that had 60+, for example). The issue is memory-related and primarily stems from 32bit systems where it was much easier to get Out Of Memory errors on the IIS Application Pools
when performing a large operation across a 32bit Application Pool (e.g. crawling). However, if you limit each IIS Application Pool to about 10 Web Applications (again, in 32bit land that no longer applies), everything generally works OK given the Web Applications
do not have a very large amount of content.
But, if HNSC is in use, a single Web Application should be sufficient, barring any Web Application-specific settings you might need to make.

Deployment Failure: Context path already in use
I am trying to deploy a webservice using a stateless session EJB, similar to the
"trader" example that comes with weblogic 8.1. I used the "trader" source files
as a blueprint for my implementation... the service builds successfully via ant,
but the following error shows up in the server console:
<Error> <Deployer> <BEA-149201> <Failed to complete the deployment task with ID
6 for the application appsdirwebservice_modelread_ear.
weblogic.management.ApplicationException:
Exception:weblogic.management.ApplicationException: prepare failed for webservice
Module: webservice Error: Context path 'webservice' is already in use by
the module: webservice application: appsdirwebservices_trader.ear
What exactly is the "context path", and what do I have to change in the .properites
or build.xml (or other) files in order to avoid this error?I do not know Contribute 2, but what I do know that in later
versions of the program, this message means that you have another
connection in Contribute pointing to the same webaddress.
Check this by doing the following:
1. in the main menu go to Edit>My Connections
2. check all connections there to find the path you described
3. delete or adjust this connection -
How to set the servlet context path manually in Tomcat web server.
I tested some servlets by putting them in the folder , which the tomcats examples application uses (ie Tomcat 4.1\webapps\examples\WEB-INF\classes\) and it appeared to be working fine.
I was calling the servlet like this : http://localhost:2006/examples/servlet/TestServlet
But when I installed my own WAR file in the server , the servlet is not working now. now the new location of my servlets is : Tomcat 4.1\webapps\MyApp\WEB-INF\classes\
and I'm trying to call the servlet like this : http://localhost:2006/MyApp/servlet/TestServlet
The error , what i'm getting is :
description :The requested resource (/MyApp/servlet/TestServlet) is not available.
Some body please tell where I'm making the mistake ? I believe this may have something to do with the servlet context path setting. If anybody has any idea , how to set the path..will be much appreciated.Thanx for your reply , at first I was not using any web.xml(since not mandatory) but even after using the web.xml file the error is coming . Please have a look into the contents of the web.xml file and let me know if you find any problem...

</web-app>
one more thing I would like to tell you here. I was just looking into the configuration of Iplanet web server..I found that , there are options to set the servlet container path (like : - Prefix: /servlet
Servlet Directory: /ecomm/iplanet/nes60/product/docs/container )
so from here I came to know that "container " is the folder where we should put our servlets and it has URI as "servlet" but yet I'm not able to find any option in the Tomcat Web server to set the servlet container to any different directory.
If you have any idea please let me know. -
Hi all.
I have a strange problem, that I hope some of you can help me with.
First of all let me explain my setup:
1. I have a faces page, that in an action method does a redirect to a different server.
2. That server then redirects back to a Servlet on my application server.
3. The Servlet then forwards to one of my own faces pages. (same context)
4. Page is displayed, BUT the form tag is now rendered like this:
<form id="form1" method="post" action="/app/servlet/testpage.jsp">
should have looked like this:
<form id="form1" method="post" action="/app/testpage.jsp">
Somehow the Servlet (context?) is added to the context path???
More info:
The way I do the forward in step 3, is like this:
LifecycleFactory lFactory = (LifecycleFactory) FactoryFinder
.getFactory(FactoryFinder.LIFECYCLE_FACTORY);
Lifecycle lifecycle = lFactory
.getLifecycle(LifecycleFactory.DEFAULT_LIFECYCLE);
FacesContextFactory fcFactory = (FacesContextFactory) FactoryFinder
.getFactory(FactoryFinder.FACES_CONTEXT_FACTORY);
FacesContext facesContext = fcFactory.getFacesContext(
getServletContext(), request, response, lifecycle);
Application application = facesContext.getApplication();
ViewHandler viewHandler = application.getViewHandler();
String viewId = "";
UIViewRoot view = viewHandler.createView(facesContext, viewId);
facesContext.setViewRoot(view);
String outcome = "ok";
NavigationHandler navigationHandler = application
.getNavigationHandler();
navigationHandler.handleNavigation(facesContext, null, outcome);
lifecycle.render(facesContext);Guess that's might be a cause to the problem?
Have tried a plain servlet forward (and then no additional context is added..., BUT causes lots of other problems)
request.getRequestDispatcher("xxx").forward(request, response);Will really appreciate some input on this.
Thanks in advance.
Edited by: mikfu on Jan 5, 2009 9:44 PMHi - me again.
Can anybody tell me is this should be the expected behaviour for such a setup?
I tried another setup, where I redirect to a page within the same application context, and is still getting same problem.
Thanks. -
GeneralException Node(( Context path of node ): cannot bind or add element,
Hello all,
Stack trace :
GeneralException Node((<Context path of node>): cannot bind or add element, because it is already bound to a node
I am trying to upload data from excel file in web dynpro context.In the process, when I create and add an element to the node which I want to populate with excel data, it throws the above mentioned exception.
Any idea as to wht is causing the problem ?Hi,
GeneralException Node((<Context path of node>): cannot bind or add element, because it is already bound to a node
It seems that its a mapped node, try to bind or addelements at the source.
Ex: If this node is mapped from controller to view try to add elements in contoller instead of doing in view.
