Can JSP pages run in a Palm OS PDA

Has anyone been able to run it? How though?

Just remember that the JSP is going to render HTML output (usually) when you access them. Provided the PDA browser can render the HTML your fine. As mentioned, applets may be out of the question so might other extras. If your developing for PDA browsers I would recommend using plain HTML with little enhancements (javascript, plugins etc) as possible or use straight XHTML which is usually better suited to PDA's.
You can also tell what type of device is requesting the page through the header fields (request.getHeader(String headerName)) and take action based on that value.

How can JSP pages be in WEB-INF?

Hi, I read in a tutorial that anything in the WEB-INF folder is basically private to the outside world, meaning they cannot access it.
I also read that JSP pages should be kept in the main folder of your application and any subfolders, but out of WEB-INF (which is for libraries, classes, and xml files).
However, another tutorial has instructed me to put some JSP pages in the main application folder, and some results JSP pages in a subfolder of WEB-INF, and it still works!
How is that so? The WEB-INF JSP pages are being accessed through a forward tag in my struts-config.xml file.

users can't directly access WEB-INF, but your app can.
just change the URL to point to the protected JSPs

Hi Raul
A better option would be to switch to Reports 9i because it natively supports Reports JSP tags. Your JSP then becomes seamless. And much more...
With 6i, you can look at using Reports Servlet.

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

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.

Can I create multiple instances of realplayer plug-in in one jsp page?

I want to play meny video files in one jsp web page, these video files are to be played with the embeded plug-in of realplayer, each plug-in was linked(use its SRC property) a different video file. But, to my surprise, when I press the play button, every player played the same video file,not its specified file.
I have no idea why it did so and what can I do?
Whether can I create multiple instances of realplayer plug-in in one jsp page, that is to say, each instance is independent of others?
thanks in advance!

Generally speaking, Internet Explorer tries not to launch multiple versions of a plug-in. So what's happening is that you load the first video clip, and then before it has a chance to play, you load the second video clip into the same window. (It's like changing songs in WMA.)
In some cases - this may not work for Real Player, but it's worth trying - if you spawn a new window through a hypertext link and then launch the plug-in in that window, IE will treat it separately. Otherwise, you could not, for example, run two Macromedia Flash applications from different web sites at the same time.
Keep in mind that only one program can access the soundcard at a time, so Real Player may purposely "pause" or "cancel" other video streams until the active one finishes. If you were using the desktop version, selecting another video by any means aborts the currently running video (i.e., RP won't let you create a separate instance of it).
The easiest solution is to create a wrapper JSP file that takes the name of the video clip, and plays it. Call that JSP and specify that it should be opened in a new window via the TARGET keyword in the anchor tag. Then hopefully RP itself won't block a second window from running.

How can I stop the execution on a JSP page and start it again

Hi
I am making a program that simulates how to manage transactions when accessing a database by using locks. I have run into a problem and I hope someone has the time to help me.
When a user does an update the transaction commits and releases its locks when the program executes
<%stmt.executeUpdate("commit!"); %>
I need to put a break in to stop the program executing this statement, to illustrate the lock is set correctly.
I have tried to put in an alert box but this does not prevent the rest of the java code being executed.
I have tried to use prompt boxes, JavaScript functions, but these functions cannot have any java code in them.
I have tried using the java.swing JOptionPane boxes but this didn?t work either
I have tried to get input from the user but I don?t know how to retrieve this data on the same page. (As far as I know you have to use submit and even refresh the page or retrieve it on the next page).
Does anyone know how I can stop the execution on a JSP page and start it again (on same page)
Mette

I already have another client (Tomcat jsp application) running and it throws a SQLException correctly when I don�t put in a commit=true statement and don't close the database connection.
But the problem is how to get the code above to stop to illustrate I have set this lock.
I have tried to use the JOptionPane but because my program is running in a web browser I cannot use the JOptionPane dialog box.
I have tired using an alert box but it executes the commit statement before the alert box is dispayed. So this does not work
While (i < 2)
if( i==1)
%>alert(�The transactions commits when you press Ok�); <% //what it to stop execution here
else
stmt.executeUpdate(�commit�);
I am not using threads so I cannot use the sleep function.
I am using mysql and have already configured it to detect deadlocks and how long to wait for locks.
Thanks for your help
Mette

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

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.

Method oadbtransaction not found while running jsp page

Hi all,
We are trying to use the below method in jsp, but when are trying its giving error as the method OADBTransaction is not found in corresponding directory, can you please let us know from where we need to download this method from server so that we can run the jsp page from local directory.
Thanks in advance.
AppsContext context = ((OADBTransactionImpl)getOADBTransaction()).getAppsContext();
Regards
Deb

Deb,
To get the object of AppsContext we use following code in jsp
import      = "oracle.apps.fnd.common.WebAppsContext"
WebAppsContext wctx = null;
int userId = 0;
try {
              if (Utils.isAppsContextAvailable()) {
                  wctx = Utils.getAppsContext();
                  userId = wctx.getUserId();
catch (Exception e) {}Regards,

Taglib repeating in jsp page in TOMCAT. (Can this be Tag pool issue? )

Hi,
We have an application and it is running fine on one servlet container "ServletExec". We are migrating our application to Tomcat and some weird things happenned.
In one of my JSP pages say page " A ", I have included another small JSP say " B "which just created a table with one row and various columns.
Now the columns are created in a taglib. And I am using that taglib inside that page " B".
Now this is working fine in ServletExec.
But in tomcat when I refersh page A or come to this page dfrom some other page, there are multiple instance of tables from page B are rendered.
SO every time I refresh a new entry added to already existing table.
Can any one please help?
I looked in some documents and found that this may be because of some Tag pooling in Tomcat newer versions. Is that right?
If yes how can I remove this tag pooling in my taglib java class?
Any help is highly appreciated.
Thanks

Hi
try disabling the tag pooling and check the page.
To disable the tag pooling in Tomcat
make enablePooling = false for the jsp servlet declaration in
$TOMCAT_HOME/conf/web.xml

How can I make the jsp pages not displayed by using the navigation class?

I'm right now implementing a function on my program GUI . It's like whenever I click "STOP THE SERVER" button on the main page, I need those jsp pages relates to the server running to be not displayed, even by directly type in the URL(that's just stay in the main page), How can I do that? I heard that a navigation class might do it, but I'm not sure how. It might be great if some experts could help me!! Thanx a million !!
