IPlanet WebServer Hangs on JSP file change

Hello,
I am using IPlanetWebServer-Enterprise/4.1SP5 and the server just hangs when there is a JSP file changed after the first successfull load. Looking at ther errors log, I can see that it is doing:
compileJSP(): invoking Java compiler, file =/.....
When the first time its successful, it follows that compilsJSP() with
For JSP Compilation : JDKLocation-/usr/java/, fork_java_c=no,enable_debug=yes
Is there a fix for this problem?? Please help
Thanks

I did all of the 3 things that you told me in the context.properties file.
The same behavior is still happening....here is the sequence
1) start the server from scratch
2) load the jsp file (ok)
3) change the jsp file with emacs
4) reload the jsp file (ok, see the changes)
5) change ths jsp file with emacs again
6) reload the jsp file (HANGS, browser is just waiting for reply)

Iplanet webserver 4.1 JSP problem

Hi I am using iplanet webserver 4.1, whenever i change my jsp file, i have to restart my webserver instance otherwise ia gm getting error..is ther any way i can prevent to restart the webserver?

this is the script.
mv /logs/https-`uname -a`-443/access /logs/https-`uname -a`-443/access.yesterday
compress /logs/https-`uname -a`-443/access.yesterday
/opt/netscape/server4/https-`uname -a`-443/restart
the moving and compressing works properly but the restart command doesn't actually kill the and restart the httpd process, and doesn't create the access or error log.
The restart is a graceful restart will not ask for password, the same setting was working fine for a long time. it suddenly started to give this problem.
the webserver is working fine(taking requests ,etc) except that the log files are not being written.
i did a truss and the data collected is above i see that it is giving error #91 ERESTART many times
there is another server with same settings which is working fine the only difference is that its patch level is lower.

Where to place my java bean files in iplanet Webserver 6.0

Hi,
I have installed SunOne iPlanet webserver 6.0 (Not Application Server). I have written very simple jsp program, that will instance a java bean (not EJB).and say Hello world. I have written test.jsp I have placed under c:\iplanet\servers\docs (root webdirectory). Where do i need to place helloBean.java file in iplanet webserver 6.0. Even i have created WEB-INF\classes & WEB-INF\lib folder under c:\iplanet\servers\docs I have created a .war file, that also put in classpath of iplanet. Finally i am getting here message that, helloBean.not found, when i see the error log file. Do i need to create jar / war file to do this simple program ?
Please answer me, i am very much interest on this.
Thank a lot
Regards
- Thilip

c:/iplanet/servers/docs/firstBean
But i am getter error msg that firstBean.databaseBean class not found.

Delete or change JSP files

Hi Guys,
when I delete a JSP file in web, I've still access to the deleted file with InternetExplorer. When I change and save a JSP file the InternetExplorer shows the old version.
How can it be? How can I delete or Change the file correctly?
The other discusions brought me no solution.
http://scn.sap.com/thread/1772196 I don't have autorization for this solution.
I'm using MII 14.0 SP4 Patch 2.
Regards,
Matthias

Hi Mathias,
You can try using "Publish" option on right click of the parent folder of the JSP page or on the WEB folder of your project. The reason you are still able to access deleted file is that the file is still on the server and a publish would re-copy the contents under the folder on to the server.
Same is the reason for you not being able to see the changes that you do in JSP page. Try "Publish" after any changes to web resources.
Hope this helps!

Ria

Tomcat doesn't pick up the changes to jsp files

My original problem was JAR locking. I changed context.xml files both in conf\ and my application.
jakarta-tomcat-5.5.9\conf\context.xml
<Context reloadable="true" antiResourceLocking="true" antiJARLocking="true">
 <WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>myApplication\META-INF\context.xml
<Context reloadable="true" antiResourceLocking="true" antiJARLocking="true">
 <WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>Now I can undeploy without having jarLocking problem.
But now tomcat doesn't pick up the changes to jsp files automatically!!!
I have to undeploy/deploy even I just change jsp files!
What's wrong?

You can't do anything except speak in a different accent. Apple would have to add specific support for different accents in a future iOS update.

Unable to change .jsp file at runtime using weblogic 8.1 server

Hello all,
I'm running weblogic 8.1 and the development environment is workshop.
I have several .jsp files in the application.
when the server is running and I try to change the .jsp file and access it throw the browser, I'm getting compilation errors and when I copy the original file again everything is OK.
I'm gessing the problem occurs due to the date of the new .jsp file(if I compile the .jsp file it creates a new servlet with newer date then the file generate when compiling the application before running the server).
Your advice will be welcome.

Hi Robert,
Take a look at the SAP Note "[1553921 - Is there a utility that would help in writing database logon code?"|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_bi/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333533353333333933323331%7D.do]
The utility provided in above SAp Note will generate the logon code for your existing report, update the logon information of the target database in the code.
Also search for the sample application 'change database at runtime' in top right corner search box.
Hope it helps,

My JSP file does not reflec the change of a Bean

My test environment: Win 2000, JDK 1.3.1, OC4J(standalone)
My problem:
In servlet, the change of a Strng value is reflected at the next refresh of a browser.
But, when a jsp file call a bean's getXXX(return a String value) method, and if the String value of that bean is changed, the next refresh or visit to that jsp file does not reflect the change of that bean.
For example:
1) TestClass.java
public class TestClass {
private String txt;
public class TestClass {
txt = "Test"; ----- (g
public String getTxt() {
return txt;
2) test.jsp
<html><body>
<h2>
<% TestClass test = new TestClass(); --(h
out.print(test.getTxt()); %> --(i
</h2>
</body></html>
In my first vistit to "http://localhost:8888/test.jsp" the brower shows "Test" String, but after I change the txt value to "Test1"((g) the brower does not reflect the change.
I found that if I use <jsp:useBean id="test" class="TestClass" /> instead of (h-(i line, the brower reflects the change of the bean.
Why does this occur?
Thaks in advance.
PS) In some cases(Not above example), I get the java.lang.ClassCastException.
So Each time I change a Servlet or a Bean, I restart OC4J.
null

SangKyu,
<jsp:useBean > has a property called scope, which defaults to "page".
So the bean gets reset everytime you reload the page.
Can I suggest that you set it to "session"?
The following syntax card I have found userful:

Where do I deploy my jar and jsp files in iplanet server directory ?

I am new to iPlanet webserver , we are using version 6.
can anyone give me brief explanation to this. Thanks.

Hi,
Please follow the below steps for running JSP & Servlet in iWS6.0
What Does the Server Need to Run JSP.
iPlanet Web Server 6.0 includes the Java Runtime Environment (JRE) but not the Java Development
Kit (JDK) due to licensing restrictions.
The server can run servlets and precompiled JSPs using the JRE, but you need the JDK to develop
new JSPs or to deploy uncompiled JSPs.
Configuring JRE/JDK Paths.
 To specify the path to the JDK.
1.Switch to the Web Server Administration Server.
2.Click the "Global Settings" tab and select "Configure JDK/JRE Paths".
3.Specify the path to your JDK. This is the path up to the level where the bin, lib, etc.
directories exist.
Java Server Pages
Ensure that JSP are enabled.
Test JSP :
Open a browser and access your servlet with the following URL :
http://hostname:port_number/jsp/Helloworld.jsp
 Using Servlet Pages 
Access the Administration Server
1. Simply start a browser and type the following URL in your browser :
http://hostname.domain-name:administration_port
2. You will be prompted for you administrator User ID and Password. Enter
the correct information.
3. In order for Servlet to execute properly, there must be a designated Servlet directory.
By default, "Servlet" is defined within your document root.
 Test Servlet 
Open a browser and access your servlet with the following URL :
http://hostname:port_number/servlet/HelloworldServlet
For deploy Webapplications, I hope the below link will help you.

Hi,
Is your web server forwarding all requests to Application server (web logic). If so you need ti have those files in the app server doc root.
give more details like what you are using passthrough or reverse proxy for request forwarding to Weblogic from Webserver.
thx

Accessing my own class members from the JSP file

Hi,
I have created a class by name simple.java.and the package structure is like sridhar.source.useful.In this package i placed my file simple.java.
Now i import this file with the import statement in JSP like
<%@ import = "sridhar.source.useful.*" %>
Now from the JSP file i want to execute some of the methods in simple.java.
I tried this one by importing the simple.java in my JSP file,but i am getting some errors:
variables that i have declared in Java files are not defined.
The JSP is not importing the class simple.java
I am executing my JSP in weblogic6.1(webserver is IPlanet)
shall i need to set any classpath for this in the weblogic shell script??
pls clarify me if any configuration is to be made or not??
regards

For JSP with IPlanet/weblogic and imported custom classes:
Put your class / package in the correct folder. $path is any path you want....
Ex: package foo, class foorbar must be
$path/foo/foobar.class
All classes must be .class, not .jar.
Weblogic/IPlanet must be configured to have the CLASSPATH
$path/
(do not include foo/foobar!)
The JSP has
<%@ import "foo.*" %>
Your class may now be used just like the other imported classes. Say you have an object Foobar with a constructor, you can just say
Foobar myFoo = new Foobar();
I do this with my classes, so if you have any questions, just ask.

Webserver in seperate exe file??

Hi Guys
So - I'm developing a piece of software that aqquires data from a USB board - this has been working well for years, everybody is happy..
Now I want to publish the results to users via the NI web server.. Using the web publishing tool I have created a html doc from a sub VI within the main application with the front panel I wish to publish, and that displays various values updated every 5 seconds..(the monitor function, NOT remote control).. I quickly realized that when a number of browsers are looking at the VI my main application starts to hang - have not been able to fully understand why, but I guess the NI core waits for each request to be shipped.. not really a problem since I'm not doing a VI to be published on facebook with +1.000.000 viewers - but since it potentially stalls the entire application, I risk that my measurement is disrupted, which is a no go, since the measurement may be in the field somewhere, and not next to a guy at an office desk.. Thus - I moved the call to the sub-VI into an external call using a static VI reference and the front panel open / Run methods and the "wait untill Done" flag set to false.
This too is working very well and inside the development system I can now "sabotage" the application with multiple hits on the "refresh" button of a browser without stalling the application.. now problems arise - part because I do not have a full working knowledge of how the runtime engine operates, i guess - but... when I build this program into an exe, I can again stall the program by hitting the "refresh" button fast.... I assume that the runtime engine treats everything called from within the exe file in one thread??
Questions:
Is there a way (in a labVIEW .EXE file) to call a VI from another VI that totally separates them from each other so that if 'mainprogram' calls 'webserver', and 'webserver' hangs for some reason, this does not cause 'mainprogram' to equally hang? Could I for instance change the execution system of the VI with all 'webserver' related contant in the "execution" options?
If not - I guess building two exe files 'mainprogram' & 'webserver' and then launch 'webserver' using system exec from 'mainprogram' will prove a solution.
however - this means that now passing of data is no longer possible - in 2010 using lv8.6, what is the best means to move data back and forth between two seperate exe files? Ideally I would send a cluster of refnum's of the indicators from 'mainprogram' then read the values of these in 'webserver' and update the display here - but is the reference addresses from one exe, anything worth in the other exe (two seperate address spaces etc)?
Should I learn to use datasockets - or would a TCP approach be the best? We are not talking massive amounts of data - in the area of 15 value and string controls + 2 graphs with less than 1000 points. Remember that this should only be done locally between two exe files on the same computer, to I would prefer to keep this as simple as possible - something like a pipe used in Unix code.
Last but not least - is there a way to run 'webserver' as some sort of service, so that the user will avoid having a window open he does not need, or a minimized 'webserver' window in the taskbar?
many questions - and yes I know that I can read all about datasockets and TCP in the forum halls - and I'm doing it, but I would prefer to not waste too many days brushing up on new stuff not needed because my plan is wack from the start..
Thank you for your help.

this is my question regarding the .exe files.
what if i whant to make my project available for every one, not only for those that already have jre instaled, and someone that doesn't know or doesn't want to install jre want's to benefit from it????
what do u have to answer to that??
a serious answer please..!!

Hi,
First thing are you seeing any request coming to weblogic server? if not then,
What configuration you have added in server.xml and virtual server instance object conf file for weblogic integration.
It is pretty straight forward,
1. add weblogic plugin libproxy_61.so in plugin/weblogic directory on webserver.
2. add WLS cluster server/ standalone server information in server.xml
3. in object file create a new object of type="magnus-internal/directory" add WL specific configuration and then add condition to select WLS object created or make it default object for handling all request.
Thanks,
Ranjan

WLS 5.1/iPlanet 4.1 and JSP

Hello!
We are using Weblogic 5.1 and Netscape's iPlanet as a proxy server. Both
the machines are running of seperate NT boxes with static IP addresses.
All the changes which need to made on iPlanet side (i.e. copying
proxy36.dll, modificatiopn of mime types file, changes to the obj.conf
file etc.) have been made. Howver I am still not able to get the JSP
forwarded to Weblogic to get them serviced.
When I try to execute a JSP, I get the "Internal Server Error". On
analyzing the
error message sin the log files for iPlanet it reports that it is not
able to connect to
Weblogic.
In order to fix this porblem I just copies the proxy36.dll for Weblogic
version
4.5.1 and copied it in the required iPlanet directory. This seems to
have fixed
the problem of getting the JSP serviced by Weblogic, but I am wary about
the solution.
Am I doing something wrong or is there a new files availabel for
download. I checked
the website for BEA and did not find any answers.
I had this evironment set up pretty quickly when using Weblogic 4.5.1.
Any ideas? Anything I might have overlooked. I have pretty much follwed
all the instructions specified by Weblogic to set up Netscape as a proxy
server.
Any help in resolving this problem would be greatly appreciated.
Thanks.
Vijay R

I have the same setup but it's on one NT box and works OK. Make sure you have the proxy36.dll from Weblogic 5.1 Service Pack 6. Release notes say you MUST have SP6 proxy file to work with iPlanet 4.1
