Running JSP content that is NOT in a jsp file
What I would like to do is this:
I have an application deployed as an ear file. I would like to add JSP
files while the server is running (much like you can do in exploded
format).
Furthermore, I would like to have the JSP content stored in an
external medium, such as a database. As far as I can tell, I cant work
out how to make JSPs run from anything other then a file relative to
the context root (and fixed in the case of an ear).
There must be a weblogic JSP engine class that I can extend/decorate
to read the JSP from another location.
Any ideas?

You're probably better off looking in a different direction, by having your
application use dynamically generated XML along with transformers.

Firefox is displaying content that is not in english
Since Firefox went to 4.0 I'm having content on web pages displayed in some odd language. It's like something is set to something other than English. When I copy and paste the gibberish it paste in english
Sounds like a problem with fonts that do not work or are corrupted. Try to reinstall the font(s) that are used on those web pages.

I am confused why my reply includes content that is not permitted
I tried to reply to this topic:
http://discussions.apple.com/thread.jspa?threadID=2691835&tstart=0
and got the "you have included content in your post that is not permitted":
I can't even quote my reply here (was met with the same warning) and am quite certain I did not violate the terms. This is very upsetting - how can I go about finding out what I did wrong?Thank you, LS; nothing from hosts at this point.
What I said - in different words - was something like the OP might have answered his own question if he set up his messages to be stored on the server; that I only have POP but thought if it was an i... account it may have something to do with those settings and that he could move the messages to a different mailbox to make sure the messages would be available in Mail.
We'll see if this wording will make it; and, yes, I've read the ToU many times, and do not understand why this would not be permitted.
As it is now, the poster's question seems to have been answered with similar suggestions, so mine (which would have been the first reply) is no longer of value; but I'd still like to know which part I violated.
Edit - got the same message; deleted the server name and inserted ... and now it worked? At least one of the replies included the server name (three letters starting with an "a") and were successfully posted.

Internal Server Error while running JSP file (Oracle AS - HP Unix)
Hello Friends,
I have created a JSP file in which I am trying to connect the database using oracle.jdbc.pool directory. But it shows an error message as:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
the path for pool package is:
/appltest/apps/prodora/iAS/oem_webstage/oracle/jdbc/pool
the location of JSP file is:
/appltest/apps/prodcomn/portal/TEST_test/test
What I think is I have to play with the CLASSPATh entries, but dont know how. Please help me in solving this issue...
For your reference the JSP code is:
<%@ page import="java.sql.*, javax.sql.*, oracle.jdbc.pool.*" %>
<jsp:useBean id="ods" class="oracle.jdbc.pool.OracleConnectionCacheImpl" scope="session" />
<%
try
ods.setURL("jdbc:oracle:thin:@test:1546:test");
ods.setUser("kpm_hr");
ods.setPassword("kpm_hr");
Connection conn = ods.getConnection();
Statement stmt = conn.createStatement();
Resultset rset = stmt.executeQuery("select first_name,last_name from kpm_hr.kpm_hr_emp_mst where empcode='P0580'");
rset.next();
out.println(rset.getString(1)+" "+rset.getString(2);
catch(SQLException e)
out.println(e);
Thanks in adavnce,
Ankur
Regards,
Ankur BhatiaJust to verify, which relevant log files have you found?
catch(SQLException e) {
out.println(e);
} Have you search the console log file?
A quick observation reveals that your jsp is just a standalone java program executed inside jsp. Suppose you just run it as a standalone program. Any error then?
Another way going forward is to install oc4j standalone of the same version. It is very easy to install: just download the oc4j-extended.zip and unzip it and run "java -jar oc4j.jar". Put you jsp inside j2ee/home/default-web-app and run. You should see relevant log messages in j2ee/home/log/server.log and j2ee/home/application-deployments/yourApp/application.log.
You should have Jdeveloper of some appropriate version installed. If you have not, install one. It might be not a little bit high learning curve at first, but the rewards are quick and amazing, especially since jdev 10.1.3. (I am speaking from my experience.) Try it with Jdeveloper. -

Problems running jsp files with tags on tomcat 4.0
hi,
i had some jsp1.1 stuff running on tomcat3.3.
last week i moved to tomcat 4.0 , changed the tags to fit jsp1.2 and... everything is wrong now. while trying to run jsp with tags i get an error message (same for all files):
---->
description The server encountered an internal error (Internal Server Error) that prevented it from fulfilling this request.
exception
javax.servlet.ServletException: (class: org/apache/jsp/djsp$jsp, method: _jspService signature: (Ljavax/servlet/http/HttpServletRequest;Ljavax/servlet/http/HttpServletResponse; )V) Incompatible object argument for function call
<-------
the jsp files with no tags and servlets are running ok.
I NEED YOUR HELP!!!cyclid,
i have the same environment setup and the same troubles. after searching the forums, it seems that there are others with the same, if not similar issues, yet no solutions. if you find the solution to this one, could you please post it. i would really appreciate it since i have been on this one for several days with no success. i even tried the helloworld jsp/custom tag examples from a jsp profession book that i have and that won't work.
Anyone out there,
if you have any idea why this problem exists, any solutions, ideas would be appreciated.
thank you,

Hi,
This is the first time I post message on the forum. The problem is that when I run the JSP files with Tomcat 4.0.1. It give the error messages. But I have put the class files under the root, such as ...\WEB-INF\classes, however, it doesn't work. Also I have set the classpath for tomcat. Is there any step I have missed?
Please give me some solution as the problem has annoyed me for a long time.
The error message is:

Here's the deal. Every Java class is in a package. If it is not declared the it is the default package but the default package is based on the directory it is in.
The DBSession class is in WEB-INF/classes and the jsp gets compiled into a class file that is placed in a different directory. Since the two class files are in different directories they are in different default packages. Thus the import.
Most people don't run into this because they put their tags into packages and import the packages.
To make everybody happy, put your tag in a package, recompile it and then import the package. -
why i can't run my jsp file? but some of them can be run ?
i use tomcat.
this is my snippet code :
<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*" errorPage="" %>

</html>i can't run above jsp file. why ?
am i being hacked ? i use IE 5 althought sometime i use netscape 6 or Opera 7.
i try to run another jsp file, it's succeed but with above simple jsp file, it can't.
but when i tried to run it on another computer, it runs.
HELP ME!Once again, I HAVE SAVE IT!. and i make sure that the
file name didn't mistake.
but when i run it, the link doesn't have any link to
anywhere.Maybe your link is incorrect.
>
the other step i take, save as the file to another
name and then run it again, but it still the same.
the change i have made is useless.
Just for this file (suppose we call it trouble.jsp).
for another jsp file, when i run it, it works.
but, for this trouble.jsp, i found it very weird.Weird won't help anybody fix your problem.
>
I'll repeat once again, i have save it and make sure
the name is correct, the path is correct when i run
it.Then everything's fine, I guess.
Yes, sometime we make mistake and let other people get
the blame.
but, for this, i found it weird.The machine is only doing what you told it to do, and what you told it is quite incorrect. There's nothing weird about it.
>
according to me, i have set my tomcat very well.Maybe you aren't the best judge.
from the start i use it, it works fine and give me
result the way i expected.Then why are you posting anything here? Sounds like you know everything and that all is well. -
Can't run jsp files in Jdeveloper
I have some existing jsp files and when I compile these files, Oracle9i Jdeveloper keeps telling me "Error: JSP files must reside in the server root directory or a subdirectory beneath it".
I originally think that's because of "import" and I got rid of all "import ....", and the same error message still insists.
Please help, thanks!:-).Hi All!
I have just downloaded jdeveloper 9.0.3.3 - and I have run into a similar issue...
1. I created workspace by selecting new workspace from wizard
2. I created a new project -- from existing (previously tested using Resin server) code -- and, I select the "copy files to project directory" checkbox in the "wizard" dialog
3. when I rebuild the project in jdev9033, for each jsp file name I get this message, i.e.,
"Error: JSP files must reside in the server root directory or a subdirectory beneath it"
what does this mean for me do?? (btw - I am using the default server that is integrated within Jdeveloper)
In my working "existing code", my jsp files are loosely located under my "myProject" folder (which also contains the "WEB-INF" and "src" folders.
Where, in my existing code, does JDeveloper expect to my the JSP files to be?....In a "JSP" folder?.... Or, where - within my new workspace/project - should I copy these JSP files in order to make this error message go away??
Thanks for you help!! -
Can't find the imported java class when run .jsp file
Hi,
I want to run a jsp web application using tomcat. I put all my .jsp files under "TOMCAT_HOME/webapps/junmin" directory, and put all .class files under "TOMCAT_HOME/webapps/junmin/WEB-INF/classes" directory. I set up TOMCAT_HOME AND JAVA_HOME already. But when I type in the address like below:
http://db1.acad.emich.edu:8080/junmin/login.jsp
The IE will give me error msg indicating that it can't find all the .class files which I imported them in login.jsp file.
So, does anyone know that if I miss some configuration in order to let the .jsp file recognize the .class files. Thanks a lot!
Sincerely, JunminHa, this might be the reason.
Can I add sth like this:
<Context path="/junmin" docbase="junmin" debug=0 reloadable=true>
</Context>
But in my local computer, I didn't add this <Context> either. It works well.
Thanks a lot! I will ask the administrator to try this.
And will write down the reason.
Sincerely, Junmin -
How to list files that are NOT in a .jar file?
Is it possible to list files (resources, .gif/.jpg files, etc.) that are NOT included in the jar but are still to be considered part of the application somewhere in the jnlp-file?
My applications requires lots of icons which I have put into .gif files. So far I kept them in individual files next to the .jar file and that worked fine.
JWS now seems to support only stuff that is included in (a) .jar-file(s). That in itself woul not be much of a problem, however, when I include my .gif files into the .jar files they seem to get corrupted by the jar-signing process (at least that what's the code says, which can suddenly not handle these images any more).My previous seem to have been non-sense. The .gif file were not corrupted, but rather they were not found at all. They actually must NOT be included in the .jar file, or else they are not found. Strange enough, the .properties-file seemingly HAS to be in the .jar file to be found.
This is something I'll probably never fully understand with java: which file-types it searches where...
