Custom Tag for Logging?
I would think that there must be a weblogic custom tag that I can use in my jsp
to access the weblog.log file - but I can't find any info on it. How should I
be logging from within jsp's?
Thanks,
Dave
You can use the NonCatalogLogger class:
http://e-docs.bea.com/wls/docs61////javadocs/weblogic/logging/NonCatalogLogger.html
It's pretty easy to wrap this class in a little wrapper class or custom
tag.
Hope that helps,
Nils

Hi,
I am trying to develop a custom tag for Marquee in JSF, my usecase is to display a value from managed bean(Dynamically). please find the code below and guide me where i have made mistake
regards
Sandeep
Component class:
package customtags;

private Object[] _state = null;
private String value;
public String getValue() {
if (null != this.value) {
return this.value;

Can i use Custom Tags for Database retrieval (as per MVC pattern)?
In our project we are dealing with database, and i've used the Cutom Tags for database retrieval (as per the Article from Mr Faisal Khan) and it is working fine. But i have a doubt if it affects the performance in any way . I wanted to know if its recommendable to use Custom Tags for the DB retrieval as per MVC Pattern or shall i create a intermediate bean and then call the bean in custom tag.
Thanks
PrakashPutting database code in your JSPs certainly couples your view to the database. That's usually not good.
If it's a simple app, it might be justified.
When you start having lots of pages and complex business logic it becomes less attractive. - MOD -

Problem creating custom tags for site that has no outside internet connecti
I've created a set of custom tags that work fine until we install our app at the customer site. The customer site has no outside Internet access, and so the DOCTYPE is failing since it references the web-jsptaglibrary_1_1.dtd located on Sun's site.
I tried copying the dtd locally and got it to work, but the solution sucks because this web-jsptaglibrary_1_1.dtd file is referenced in both my taglib.tld file AND the web-jsptaglibrary_1_1.dtd itself. Soooo....I can put in a URL that references it on the local machine, e.g.,
In the taglib.tld file:
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.// DTD JSP Tag Library 1.1//EN"
"http://ClientAAA/web-jsptaglibrary_1_1.dtd">
In the web-jsptaglibrary_1_1.dtd file:
<!ATTLIST taglib id ID #IMPLIED
xmlns CDATA #FIXED
"http://ClientAAA/AdProduction/web-jsptaglibrary_1_1.dtd"
>
but that means for every client that uses this app (and we have several) I have to change that URL inside both these files.
I tried simply changing it to the relative "web-jsptaglibrary_1_1.dtd", e.g.,
taglib.tld:
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.// DTD JSP Tag Library 1.1//EN"
"web-jsptaglibrary_1_1.dtd">
web-jsptaglibrary_1_1.dtd:
<!ATTLIST taglib id ID #IMPLIED
xmlns CDATA #FIXED
"web-jsptaglibrary_1_1.dtd"
>
but then it is requiring me to put the dtd in both my web app root directory AND my jakarta/bin directory. I get the following error:
XML parsing error on file ../vtaglib.tld: java.io.FileNotFoundException: D:\jakarta\jakarta-tomcat-4.1.29\bin\web-jsptaglibrary_1_1.dtd (The system cannot find the file specified)
It seems like I must be missing something here. This shouldn't be this hard. And it seems funny that to use custom tags, you have to have Internet access in the first place.
Help!!! :)
Thanks.Yeah, I think it's a bit ridiculous that in order to make all the tag library examples and instructions work, you have to have access to the Internet. I haven't seen a single example on how to make it work if there is no Internet access. That's very limiting. And I've tried all sorts of other ways of doing it, such as
<!DOCTYPE taglib SYSTEM "web-jsptaglibrary_1_1.dtd">
but even then it won't work because I get an error message saying:
XML parsing error on file /assets/../vtaglib.tld: java.io.FileNotFoundException: D:\jakarta\jakarta-tomcat-4.1.29\bin\web-jsptaglibrary_1_1.dtd (The system cannot find the file specified)
I just don't think I should have to place this file in the bin directory. There has to be another way. Do I need to modify the dtd somehow? Cuz the dtd has the following line...is this messing it up??
<!ATTLIST taglib id ID #IMPLIED xmlns CDATA #FIXED "web-jsptaglibrary_1_1.dtd">
I sure could use some help. -
I am a bit of an organization freak. I have been using J. River Media Center to play songs, but now that I have an iPod, I am disgruntled because when I copy the songs to my iPod, the images do not come over, and half the songs don't play.
I am trying to use iTunes now, but I cannot seem to figure out how to show custom tags. For example, in Media Center, I invented new tags that did not exist to allow me to categorize my tracks in different ways. I made a Mood tag, a Principal Instrument tag, a How Discovered tag, a Country tag, a Status tag, a Fave tag, etc. iTunes does not seem to have a way to show these tags or allow me to create them. Am I missing something?
[email protected]But why not? It is a no-brainer. Why not provide people with the convenience of creating their own tags? I think I shall stay with Media Center just for this reason.
I know I can put tags in the Grouping or Comments field, but this is really a visual inconvenience when you have many tags. For example, I have a song that I want to tag with Piano, Norway, Faves and Upbeat for the purpose of creating separate playlists. I know I can set the smart playlist to say, "Grouping contains Piano" or "Grouping contains Faves", but visually this is an inconvenience, and when you have tons of songs you want to categorize in many different ways, it is more convenient to be able to create separate tags entirely. -
How to create a custom tag for a custom converter
In Jdeveloper 11g, I have a project where I have created a custom converter class that impements the javax.faces.convert.Converter class. I have registered the converter with an id in the faces-config.xml file of the project, and the converter works fine by using the <f:converter type="myconverter"> tag. However, the custom converter has a field which I would like to set from the tag itself. Hence, I would like to add an attribute to <f:converter> tag if possible or create a custom tag that has the attribute.
I have done some reserach and I found that a custom tag can be implemented: I need to create a class which extends from the ConverterTag class or javax.faces.webapp.ConverterElTag class, which I did, but I also need to create ".tld" (tag library) file which defines the tag itself.
The part about creating the ".tld" file and registring the new tag is what I'm not sure how to do.
Does someone know how to do this?
thank youHi frank,
that's a good document, and it explains how to make a custom converter. I already created the custom converter, it converts a number to any currency pattern. I know java already has a currency converter, but it doesn't support Rupee currency format, and I need that format.
My converter works, but I would like to pass the pattern of the format through an attribute in a tag. Since f:converter doesn't seem to support that, I created a custom tag which uses my converter, and it enables me to pass a pattern to the converter.
All of that works, but I need to be able to pass the pattern as an EL expression, and it's not evaluating the expression before passing it to the converter. It just passes the whole expression as a string. I'm thinking It may be something I'm doing wrong.
this is the tag library definition file:

How to use Custom Tags for Theme and Base Map Definitions
In Mapviewer documentation I've found the following new feature:
The XML definition of a theme or base map now supports application-specific
attribute tags. You can use the Custom Tags option in the theme definition in Map
Builder to specify tags and their values, which can be interpreted by your application
but are ignored by MapViewer itself.
I'm able to define a custom tag in Mapbuilder, but how can I use it in my Application?
Thanks.As he said, you have to use as Platform service to create adapter in OIM.
tcUserOperationsIntf service = Platform.getService(Thor.API.Operations.tcUserOperationsIntf.class);
HashMap<String,String> searchmap=new HashMap<String,String>();
searchmap.put("Users.User ID", userID);
tcResultSet searchset=service.findAllUsers(searchmap); -
Using Customized page for logging in
Hi all,
I am trying to use an html page for logging into Sun Identity manager.
Actually we have an html page, on which we have a section in which the user can enter the credentials.
Now when he clicks the submit button, then the user should be able to login SIM.
I thought that in backend we can pass the values entered in html page to user/login.jsp.
But i am not getting in which attributes, we should get these values on user/login.jsp because i think,in backend it also calls some form and i am unable to get which form it is calling.
Any pointers can be helpful.
Thanksi dont thik its possible use a separate html page for login.you can customise the login page(bit difficult but you can do it there are some css and .properties files are associated with that)

Custom tag for selecting BW images
I wish LR had a filter button to select the images converted to grayscale via Treatment command or 'V' button. For now I have to flag 'em either by star rating (and keep in mind not to do that with color photos) or color tagging.
>ps Do you also have to use such a user name? I'm sure you're a perfectly nice bloke but take an instant dislike to your virtual self for parading such beliefs in this forum. It would be great if you could have a neutral user name.
Also it might avoid OT, and in appropriate comments form other users, such as the one with 666 in his user name.

hello!
i have a question regarding the tag flag in rman. is it possible to create a tag that looks like weekly_2009_46 (46 is the week of the year)? if i use the command
backup as compressed backupset tag=weekly_YYYY_WW database;
the tag is weekly_YYYY_WW, but should be weekly_2009_46.
any ideas? thx!
best regards,
christianIf it is required to have the week component in the TAG, then you could use the following process to capture that and pass it to the rman commands:
E:\>type yw.sql
set pages 0
select to_char(sysdate, 'yyyy_iw') from dual;
exit
E:\>type yw.cmd
@echo off
for /f %%i in ('sqlplus -s / as sysdba @yw.sql') do @set yw=%%i
echo backup datafile 4 tag 'weekly_%yw%';
exit
) | rman target /

Simple example of a custom annotation for log
Please help me write me my custom annotations. I like to use them to provide log ,security etc . I did not find articles where I can write my annotation to change the behaviour. Suppoe I decare annotation on a method , I want jvm to call code in my annotation where I can control the behaviour of the method similar to aop stuff ,
here is what i need
MyClass {
@MyCustomAnnotation
void myMethod(){
}now I want MyCustomAnnotation to log that this method is begin called can I do this ?I can think of only one way to do something like this, and it's messy:
Let's say your code looks like this:
public class MyClass
@MyLogging
public void myMethod(String arg)
}Have your @MyLogging annotation processing generate a new Class source that extends your original class and overrides the methods that you've annotated with code that looks something like this:
public class MyClassGenerated extends MyClass
Log log = ... // create a logger
@Override
public void myMethod(String arg)
log.info("myMethod called");
super.myMethod(arg);
}Now you'll have to change your code to use MyClassGenerated instead of MyClass, which presents its own problems... you may be able to add in some kind of factory mechanism or something to make that work easier. -
Custom tag lib with output parameter
Hi,
I need a tag libray that gives me a specific element of a Vector.
Here there is the line I have in my jsp.
<ct:partizione tronco="${contenitoreCentralineTronco}" indice="index" partizione="tmpPartizione"/>
...-contenitoreCentralineTronco is an Object that contains a Vector of other specif objects.
-indice is the vector index of the specif instance I need.
-partizione should be the output instance.
This is part of my tld file:
<tag>
<name>partizione</name>
<tagclass>ss.aspi.classi.centraline.grafica.tagSupport.Partizione</tagclass>
<bodycontent>empty</bodycontent>
<info>Estrae una partizione da un vettore di partizioni dato l'indice</info>
<attribute>
<name>tronco</name>
<required>true</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
<attribute>
<name>indice</name>
<required>true</required>
</attribute>
<attribute>
<name>partizione</name>
<required>false</required>
</attribute>
</tag>
...this is part of the class called by the tag:
private ContenitoreTroncoBean tronco;
private Integer indice;
private ContenitorePartizioneBean partizione;
public int doStartTag() throws JspException {
try {
Vector<ContenitorePartizioneBean> partizioni = tronco.getPartizioniBean();
partizione = partizioni.get(indice);
}catch (Exception e) {
log.error("Errore nell'estrazione della Partizione "+indice);
e.printStackTrace();
return TagSupport.SKIP_BODY;
//All getter and setter functionsWhen I run the application I get this exception:
jsp.error.beans.property.conversion
looking deeper in the class code jenerated from the jsp, I noted that the problem refers to the third attribute of the tag <ct:partizione>.
It seems It trys to set the attribute "partizione" with the value "tmpPartizione", but partizioni should be an output attribut non input. The varible tmpPartizione doesn't exist... the tag should create it.
I realized I didn't get how I should create a tag with output parameters.
Anyone can explane me it?
Thanks.One suggestion: Take a closer look at the EL (expression language)
It has an excellent syntax for accessing collections/maps
${contenitoreCentralineTronco[index]} would exactly what you want, without having to write a custom tag for it.
If you REALLY want to do this as a custom tag, then you need to treat the input attribute as a String (the name of the variable you are going to create?) Right now your tag declares the attribute partizione as being of type ContenitorePartizioneBean which is probably the cause of the problem - you are passing it a String.
