Help needed in jsp
I am having a jsp page.. Now i am displaying a message "Updation success" after this i have to wait for 3 seconds and the page should close automatically
By the way, the word "updation" does not exist AFAIK.Perhaps it's time for a dictionary updation.

I am trying to design a view page that retrieves records from database,as the data may contain tags like<p>,<b> I am using encodeHtmlTag function to display them as it is .but some text needs to be appeared in bold but if i give the same,b. as input while viewing it is displayed as",b>" since i am using encodeHtmlTag it encodes all the tags .How i can solve this issue.?
as a way i tried using "[ " b " ]" as the tag for bold option ,but i am not able to write proper function to recognize that charater and change that tag to ",b>".
can anyone please help me in this.Thanks a Lot.Since I am at my beginning phase of jsp i am not able to I will be more thankful to you if recode my following code so that the bold option works fine with Italics.
with the following code it encodes all the"<" characters so that if i want to make some part of text as bold while retrieving from database its not working how i can achieve this with the following codes.(r34.jsp).
j11.jsp is the index page from which it forwards to next page r34.jsp which is the display page i.e it retrieves data from database and displays them.i need help in this page only.

Help needed in JSP Expression Language
Hi all,
I have been working for JSP Expression Language Sample execution since past 5 days. I am using the application server as "Jboss Server" and web server as "Tomcat".
I have been included the jsp-api.jar file in my lib directory of application server as well as source folder's lib directory.
When i am trying to build the source code, i am getting this build error.
[javac] D:\eclipse\workspace\esolvProject\development\src\com\esolv\taglibs\
web\classes\SetSupport.java:186: cannot resolve symbol
[javac] symbol : method getExpressionEvaluator ()
[javac] location: class javax.servlet.jsp.PageContext
[javac] ExpressionEvaluator evaluator = pageContext.getExpressionEvaluator();
In my jsp-api.jar , there are two classes called,
PageContext and JspContext, Both are abstract classes.
PageContext inherits JspContext class. JspContext class have the method getExpressionEvaluator() , returns ExpressionEvaluator.
PageContextImpl - class . it has been called internally when we are trying to call PageContext class. In PageContextImpl class, there is one comment before, the method's definition. that is
" Since JSP 2.0 "
But we have the JSP 2.0 version. But it won't work.
Please help me ont this.
Thanks in Advance,
Natraj>
If the pblm was due to setting the classpath.
The error should be showed for all files in the jar
file.
why i am getting the error for particular method ?
it is accessing the other methods of same class
'JspContext' . but it is not accessing that method.
Thats my question.
Just check that your .jar file is 2.0 compliant and that you do not have any other jars(for servlet or jsp api) in the classpath.
Probably you have an older version of .jar file in your path. So the errors will appear only for those methods that have been added since 2.0, all other methods would compile fine.
Please tell me the jar files to work out the
expression language. so that i can cross check my
list of jars.Hmmm...I dont use jboss. In tomcat the jar file name is jsp-api.jar. But it would have been the same even for jsp1.1, going by jar file names wouldnt help. Just look at your cp as if with a microscope to identify redundant jars.
cheers,

?? Invalid Cursor State - Help needed in JSP.
OK...here's the problem I have a page that loads the values from a database into input fields so as users could edit and update the data into the respective tables.
But the problem is i get this error which I have never come accross before. So any help clarifying this would be much appreciated.

Thanks for the help guys..I really appreciate it. -
Hi,
I have a variable declared in one of the JSP files. How can I access that variable from another JSP page?
For ex:
jsp1.jsp
<%
String hello = "Hello world!";
%>
jsp2.jsp
<h3>The string is <%= hello %></h3>
I know this code wont work. But how can I fix it?
Please let me know your solutions as soon as possible.
Thank you,
RajeshThanx a lot.
I did understand how to use session to store a java object. Actually, I wanted to use primitive data types... well, I could work around that.
But, could you please explain what you mean by storing in the application context?
Thanks a lot,

Thanks inadvance
Regards
ChintanThere is a general feeling that scriptlets in JSP pages are a bad thing.
They can make the page difficult to follow and understand.
The syntax used above was from the JSTL - JSP Standard Template Library : http://java.sun.com/products/jsp/jstl/
The JSTL tags provide a lot of functionality that previously was done in scriptlets.
eg Looping, conditional branching, formatting, XML handling.
Benefits: You don't have to constantly switch between java and html with <% %> tags. The code ends up looking much nicer.
Also it is aimed at page authors, who don't necessarily understand java, but will understand using tags like this.
Myself, I like it because of the first reason - it just makes the page so much easier to read when everything is in tags, as opposed to constantly switching from java to html and back - particularly with braces.
You have to agree:
<c:if test="${params.choice == 'yes'}">
You said YES!
</c:if>looks much better than
<% if (request.getParameter("choice").equals("yes")){ %>
You said YES!
<% } %>Cheers,

Help needed to run JSTL 1.1 in Tomcat 6.0.16
Hi All,Help needed to run JSTL 1.1 in Tomcat 6.0.16. I am trying to run the example given in http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html The example tries to connect to MySQL database from JSP using JSTL and JNDI Datasource.I am running the example using Eclipse 3.4.2 using Sysdeo plugin to start and stop Tomcat server from Eclipse IDE.
My web.xml file has <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
</web-app>
and test.jsp has proper taglib directives
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
I have placed the jstl.jar and standard.jarof the jakarta-taglibs-standard-1.1.2.zip under E:\Deepa\workspace\DBTest\WebContent\WEB-INF\lib directory also placedcontext.xml file under E:\Deepa\workspace\DBTest\WebContent\META-INF and the content of context.xml is as below

username="deepa" password="mysql" driverClassName="com.mysql.jdbc.Driver"

</Context>
Now while running the example, Eclipse creates one DBTest.xml file under C:\Program Files\Apache Software Foundation\Tomcat 6.0\conf\Catalina\localhost
which has the following line:
<Context path="/DBTest" reloadable="true" docBase="E:\Deepa\workspace\DBTest" workDir="E:\Deepa\workspace\DBTest\work" />
I am getting the following error when running http://localhost/DBTest/WebContent/test.jsp

what is the problem with my code?
When running the same example, by creating a local server in Eclipse(creating new Server connection pointing to same Tomcat 6.0 installation) it runs fine without any error.Hi evnafets,
Wow, very helpful information, great insight into working of Eclipse. Thanks a lot.
I have one more question. I have a context.xml file under {color:#0000ff}E:\Deepa\workspace\DBTest\WebContent\META-INF{color} folder and that has the Resource element to connect to MySQL database:
{code{color:#000000}}{color}<Context path="/DBTest" docBase="DBTest" debug="5" reloadable="true" crossContext="true">
<Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000" username="deepa" password="mysql" driverClassName="com.mysql.jdbc.Driver"
{color:#0000ff}url="jdbc:mysql://localhost:3306/javatest?autoReconnect=true"/>{color}
{color:#0000ff}</Context>{color}As usual when running application in local Tomcat server of Eclipse, this data source works fine. But when I run the application on Tomcat, by starting Sysdeo plugin from Eclipse, the DBTest.xml file created in C:\Tomcat 6.0\conf\Catalina\localhost has the context entry as<Context path="/DBTest" reloadable="true" docBase="E:\Deepa\workspace\DBTest\WebContent" workDir="E:\Deepa\workspace\DBTest\work">
</Context>The<Resource> element I have specified in the context.xml of \WebContent\META-INF folder is not taken into account by Tomcat and it gives the following error:May 21, 2009 5:20:04 AM org.apache.catalina.core.StandardWrapperValve invoke

So to overcome this error I had to place the <Resource> element in DBTest.xml under C:\Tomcat 6.0\conf\Catalina\localhost {color:#000000}and then it works fine. {color}{color:#ff0000}*Why is the context.xml file in META-INF not considered by Tomcat server using Sysdeo Plugin?*

Hi
I am using the following code which i got form the forum for rpinting an HTML file.

Thanks
RamRam,
I have had printing problems too a year and a half ago. I used all printing apis of java and I still find that it is something java lacks. Now basically you can try autosense. To check whether your printer is capable of printing the docflavor use this PrintServiceLookup.lookupPrintServices(flavor, aset); . If it lists the printer then he can print the document otherwise he can't. I guess that is why you get the error.

Help whit dinamyc jsp events ^^
Hello:
hummmm! need help in create jsp (xml, xsl, xslt or whatever) whit dinamic html components events like checkbox, i.e:
When i click in a checkbox or radio button, the action (event) must make me generate dinamyc html code like show fields or forms (not hide forms or tables, just generate tables or forms whit the checkbox or radio button actions). But i wan�t use javascript just JSP, XML, XSL or whatever.

Help Needed With A Java Installation
Hello,
I'm beyond being a novice with regards to Java. To be quite honest, I don't have the time right now to learn the language, nor do I have the need for anything other than what I am about to ask. I say this upfront to avoid unfriendly comments from people who may criticize my "laziness", NOT to sound disrespectful to those who post or answer questions in this forum.
With that said, here's my question...
I have a Sun/Cobalt RaQ4i server. I'd like to run a few free license Java games that I found on a website. The problem is, RaQ appliances do not ship with Java installed. I've been looking for some way to get it on my server for a few days now, with little luck. I've searched the Java help forums, the Sun/Cobalt forums and a few other help sites such as www.raqzone.com. (...which is why laziness is in quotes up there.) I did find this page... "http://developer.cobalt.com/java/java.raq.php". I have now installed both, the package and the update, on the server. However, the applet still does not run. I don't need the JSP feature, as my site is done in ASP. I don't know what a servlet is, but thought it might be similar to an applet, and would do the trick. *?* Apparently, I was wrong. Can ANYONE tell me what I need to do to get the desired results when I try to run a Java applet on my Cobalt RaQ?? I'd also be willing to be a fee to have it installed... correctly, of course! :)
Thanks in advance for any directions or guidance,
-Daniel
[email protected]Assuming you're running Solaris, you can download the Java Runtime Environment (JRE) from http://java.sun.com/
One of the provided programs is appletviewer, which you will be able to use to run applets if they are on your local machine. I'm not entirely sure about Solaris, but the JRE may also install the Java Plugin to your browser so you can view applets in the browser.
Apologies if this was already mentioned in the link you provided - registration/login is required, so I didn't read it.
I hope you have more luck with your applets,

help needed for writing query
i have the following tables(with data) as mentioned below
FK*-foregin key (SUBJECTS)
FK**-foregin key (COMBINATION)
1)SUBJECTS(table name)
SUB_ID(NUMBER) SUB_CODE(VARCHAR2) SUB_NAME (VARCHAR2)
2 02 Computer Science
3 03 Physics
4 04 Chemistry
5 05 Mathematics
7 07 Commerce
8 08 Computer Applications
9 09 Biology
2)COMBINATION
COMB_ID(NUMBER) COMB_NAME(VARCHAR2) SUB_ID1(NUMBER(FK*)) SUB_ID2(NUMBER(FK*)) SUB_ID3(NUMBER(FK*)) SUBJ_ID4(NUMBER(FK*))
383 S1 9 4 2 3
384 S2 4 2 5 3
---------I actually designed the ABOVE table also like this
3) a)COMBINATION
COMB_ID(NUMBER) COMB_NAME(VARCHAR2)
383 S1
384 S2
b)COMBINATION_DET
COMBDET_ID(NUMBER) COMB_ID(FK**) SUB_ID(FK*)
1 383 9
2 383 4
3 383 2
4 383 3
5 384 4
6 384 2
7 384 5
8 384 3
Business rule: a combination consists of a maximum of 4 subjects (must contain)
and the user is less relevant to a COMB_NAME(name of combinations) but user need
the subjects contained in combinations
i need the following output
COMB_ID COMB_NAME SUBJECT1 SUBJECT2 SUBJECT3 SUBJECT4
383 S1 Biology Chemistry Computer Science Physics
384 S2 Chemistry Computer Science Mathematics Physics
or even this is enough(what i actually needed)
COMB_ID subjects
383 Biology,Chemistry,Computer Science,Physics
384 Chemistry,Computer Science,Mathematics,Physics
you can use any of the COMBINATION table(either (2) or (3))
and i want to know
1)which design is good in this case
(i think SUB_ID1,SUB_ID2,SUB_ID3,SUB_ID4 is not a
good method to link with same table but if 4 subjects only(and must) comes
detail table is not neccessary )
now i am achieving the result by program-coding in C# after getting the rows from oracle
i am using oracle 9i (also ODP.NET)
i want to know how can i get the result in the stored procedure itsef.
2)how it could be designed in any other way.
any help/suggestion is welcome
thanks for your time --PradeeshWell I forgot the table-alias, here now with:
SELECT C.COMB_ID
, C.COMB_NAME
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID1) AS SUBJECT_NAME1
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID2) AS SUBJECT_NAME2
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID3) AS SUBJECT_NAME3
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID4) AS SUBJECT_NAME4
FROM COMBINATION C;
As you need exactly 4 subjects, the columns-solution is just fine I would say. -

Hi all help needed I have a canon 40D. I am thinking of buying a canon 6D.
But not sure that my lenses will work.
I have a 170mm/ 500mm APO Sigma.
A 10/20 ex Sigma HSM IF.
And a 180 APO Sigma Macro or do I have to scrap them and buy others.
ALL Help will be greatly received. Yours BRODIEIn short, I love it. I was going to buy the 5DMark III. After playing with it for a while at my local Fry's store where they put 5DMII, 5DMIII and 6D next to each other, using the same 24-105L lens, I decided to get the 6D and pocket the different for lens later.
I'm upgrading from the 30D. So I think you'll love it. It's a great camera. I have used 5DMII extensively before (borrowing from a close friend).
Funny thing is at first I don't really care about the GPS and Wifi much. I thought they're just marketing-gimmick. But once you have it, it is actually really fun and helpful. For example, I can place the 6D on a long "monopod", then use the app on the phone to control the camera to get some unique perspective on some scenes. It's fun and great. GPS is also nice for travel guy like me.

Help needed! Raid degraded again!
Hi!
Help needed! I hava made bootable RAID with two S-ATAII 250Gb HDD and its not working! Every now and then at bootup I get a message RAID -> DEGRADED... Must be seventh time! Rebuild takes its own time!
What am I doing wrong!
T: Ekku
K8N Neo4 Ultra
AMD 64 4200+
2 Gb RAM
2 x 250 Gb HDD (Maxtor)
nVidia RAID (in mb)
P.S. I wery SORRY with my poor language!I'm going to blame the nVRAID because I've seen issues with it in the past. If your motherboard has another non-nVidia RAID solution, use that instead. Using the nVidia SATA ports as BASE or JBOD is fine and dandy but RAIDing always had issues. It's not even a driver issue I think it's just instability. Latest drivers and even boxed drivers never helped. Granted, some will report success with their rig. But on a professional level I've seen nForce issues on different motherboards and different hard drives that had RAID disaster stories.
Good luck and if you don't have another RAID solution, my suggestion would be to buy a dedicated RAID controller card.

I feel a bann comming up.
Have you tryed Google ? really.. your question is inrelevant. No need to reply indeed.
Why do you come here asking this question anyway ? is it becouse you have a MSI gfx card ? and the adapter has nothing to do with this ?
You think you can come in here yelling.. thinking we have to put up with it and accept your style of posting. This is not a MSI tech center.. it's a user to user center.. Your question has nothing to do with MSI relavant things anyway's.
