Designing run time jsp page

hello all,
I want to design a run time jsp page.
how should i do it? using servlet or jsp has this capablity.
please give me advice to achieve it effectivly.
Can yo give me a example also of making runtime controls let say a button or label or textbox on jsp page also.
Thanks in advance.

Your terminology and English is really messed up in this message, so sorry if my answer is wrong. Especially the part "design a run time jsp page" makes really no sense.
If you want to add DOM elements "on the fly", use an ajaxical library like jQuery or adopt an ajaxical JSF component library like RichFaces/Ajax4jsf.

Javahome: C:\ j2sdk1.4.2_03\jre;
path: C:\ j2sdk1.4.2_03\bin
<there are other variables available in path, along with that I have added the j2sdk1.4.2_03\bin in path".
So if u have any way out for it please let me know.

I think you only need to add: c:\j2sdk1.4.2_01
you have specified jre on the end of your path, it is not the jre that is required, but the jdk.
If you are using startup.bat and shutdown.bat (or .sh on Linux) you can amend the files with a text editor (open the startup.bat in notepad), like so:
@echo off
set JAVA_HOME=c:\j2sdk1.4.2_01
if "%OS%" == "Windows_NT" setlocal
I this will start Tomcat with the correct settings, regardless of your environment settings.

Please help. Got TopLink working, but now I can't run a JSP page

I am using JDeveloper 9.0.3.
I got TopLink working successfully. Meaning I can access the DB using my mapped TopLink classes from my java code in JDeveloper.
However, now I can't even run the default .jsp page.
I am getting the error:
Error instantiating application at file:/C:/LBIT/LBIT-oc4j-app.xml: Error parsing data-sources config at file:/C:/LBIT/LBIT-data-sources.xml: Fatal error at line 0 offset 0 in file:/C:/LBIT/LBIT-data-sources.xml: The encoding "windows-1252" is not supported.
If I go change the "LBIT-data-sources.xml" file to "ISO-8859-1," as soon as I run the .jsp page (from JDeveloper) the "LBIT-data-sources.xml" file gets overwritten with a new one that contains the "windows-1252" encoding line again.
What can I do to fix this???
I know someone else has run into this problem!!!
Please help. Thanks so much.
Andy

You could change the encoding by doing the following.
Stop Embedded OC4J Server (Run | Terminate | Embedded OC4J Server)
Tools | Preferences
Select Environment
Change the Encoding to ISO-xxxxx
Click OK
Run your JSP now.
Atleast this should fix encoding generated into data-sources.xml

Problem in running a jsp page on tomcat 5.0

hi....
i made a java class abc.java and then compiled it to get a java class file named abc.class in a package named pkg.
Then i copied this package in the classes folder of the WEB-INF folder in tomcat 5.0.
After that i created a jsp page in which i imported this class file. Now when i run the jsp page on tomcat 5.0 i get an error saying this:

Leads me to believe that you're compiling and targeting a java version that your tomcat installation doesn't support. What version of the JDK are you using?
Good Luck

You're right, that ws another fix I tried. There is no fix fo
rthe issue described, but it still seems like an old issue. My
class paths are short. Here is my jvm.config (pretty standard):
# VM configuration
# Where to find JVM, if {java.home}/jre exists then that JVM
is used
# if not then it must be the path to the JRE itself
java.home=I:/JRun4/jre
# If no java.home is specified a VM is located by looking in
these places in this
# order:
# 1) bin directory for java.dll (windows) or
lib/<ARCH>/libjava.so (unix)
# 2) ../jre
# 3) registry (windows only)
# 4) JAVA_HOME env var plus jre (ie $JAVA_HOME/jre)
# Arguments to VM
java.args=-server -Xmx1000m -Dsun.io.useCanonCaches=false
-XX:MaxPermSize=256m -XX:+UseParallelGC
-Dcoldfusion.rootDir={application.home}/
# commas will be converted to platform specific separator and
the result will be passed
# as -Djava.ext.dirs= to the VM
java.ext.dirs={jre.home}/lib/ext
# where to find shared libraries

in case connecting to oracle database u have to have the drivers or the classes12.zip file in u'r classpath.

How to run a jsp page

hello to all of u
i m bit comfortable with SERVLET and please tell me that how to run a JSP page.i m using TOMCAT.
someplace it is written that " write the program ,save under the root of tomcat i.e in my system it is tomcat 4.1 and to store in tomcat4.1\helloworld.jsp ,,, and then after start the server write in the url --:
http://localhost:8080/hello.jsp.
but it is giving error while running.please tell me the procedure.
thank you
bye

Why oh WHY do you want to fiddle with the server.xml file?
You don't need to.
Under tomcat is a directory called "Webapps"
This is where you put your web applications.
You will see there is an existing one there called ROOT - which funnily enough is the root one used for Tomcat.
If you put your hello.jsp in the ROOT directory, http://localhost:8080/hello.jsp will work.
However it is not recommended to use the ROOT directory. Make your own one.
Create a new directory in the "Webapps" directory eg "test"
Put your jsps in here.
under test create a directory called "WEB-INF"
Copy the web.xml file from [TOMCAT_HOME]/webapps/ROOT/web-inf into the new web-inf directory.
Now go to http://localhost:8080/test/hello.jsp

Error when run a jsp page in tomcat

I carefully follow all instruction to install and config j2sdk1.4.2 and Apache Tomcat/5.0.28. After completing, I can run all sample applications about JSP and Servlet in Tomcat manager. I also test my own servlet application and it also works.
But I fail to run a very simple jsp page. Although I already set environment variables such as CATALINA_HOME, JAVA_HOME, CLASSPATH as directed but it seem to not be able to compile jsp page.
( I can compile other java classes in command line. )
Below is the error i receive . This error takes me lots of time to consider.
I look for your help ( please describe as clear as goog ). Thanks a lot.

If you are sure you've installed the JDK (as opposed to just a JRE, which doesn't come with the compilation tools that are required to compile JSPs), then your JAVA_HOME is probably set incorrectly. Ensure JAVA_HOME is pointing to the JDK directory, and not to the JRE directory.

StackOverflowError - when trying to run a JSP Page in JDeveloper

I don't see any errors or warnings in the Structure. I am going through the Veeva Vacations example from the WebCenter Demos and Samples page (http://www.oracle.com/technology/products/webcenter/owcs_10132_demos.html). There is nothing complex about the page it just contains an ADF Read-only table based on a Database table. I was able to run it successfully and then another time I ran it I got that error. It seems to me as though it is a memory issue as opposed to a page error. I am just not sure where to look to allocate more memory.

Java compilation and running within jsp page

hi,
i need of a jsp page that has a textarea in which the java coding are entered and this coding is compiled and executed. The execution result is printed.
Please guide me.

I don't think you can invoke java compiler or run time environment at client side (browser). Even if you use applet, i think you will not be able to do it at client side. Moreover, though java virtual machine will be available in your target user's browser, but you should not expect a java compiler in users machine.
I have seen exam sites where they have added java code compilation and execution ability. To achieve this you can do:
1. In your JSP page use text area where user can edit java code.
2. Provide two buttons - 'Compile' and 'Run'.
3. On click of 'Compile' send the code to server side. In server machine create a file in a temporary location in disk and save the code content received from client.
4. Invoke 'javac' command (as a separate process) to compile the java class created in step 3. This process will give you error/output back which you can send back to user.
5. In case of 'Run' you must first invoke above mentioned 'Compile' service and then another service ('Run') to actually run you java class. You can build 'Run' service in similar way.
Here you challenge would be managing multiple client requests (to compile and run java class) at the same time.

Hi,
Check this conditions as I haven't checked the queries ......make sure that these two conditions are not getting into picture after you make the changes to the query.
1) When we are making restricted key figures we cant use same variable to restrict to two different Characteristics in the same RKF.
2)Once a Variable used to restrict a characteristic in one RKF you cannot use it to restrict it other characteristic in other key figures i.e. You can use it to restrict that particular characteristic only in other key figures.
Hope it helps

Does your jar file include the libraries that you are "importing" into your code?
