Getting HTTP Status 500 error with sun one application server...

Hi,
I am trying to develop a sample application and try to run with sun one application server. I followed the tutorial. My application client is working fine. But my web client is producing the following error. I think we don't need to install Tomcat seperately when we have the application server or do I have to... any suggestions...

You do not need to install Tomcat. SJSAS contains a web container. The error you are seeing could be caused by a few reasons. There are many previous threads on this issue, perhaps you could search the forum. I used the following search term, "Unable to compile class for JSP" ,and got many hits.

Connecting to Oracle 9i with Sun One Web Server 6.1 SP4

I have an application that connects to an Oracle 9i database. When I run iPlanet 4.1, I am able to login to the application and run it. Since I have migrated to Sun One Web Server 6.1 SP4, I have not been able to login. Through some built in error logging, I have been able to determine that my user validation routine is receiving a Null pointer when it trys to connect to the database. I have also determined that my login servlet is executing properly. When I receive the Null pointer error, I am redirected to a failed login page, which is what is supposed to happen in such a case. I believe that I do not have the web server configured properly to connect to the database and I am not sure how to do it! Below is an excerpt from my code where the database connection occurs and the exception is detected. Any help would be appreciated!
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
oracleConnect = DriverManager.getConnection("jdbc:oracle:thin:@" + chost + ":" + cport + ":" + csid ,u,p);
enable = true;
oracleConnect.close();
}catch(java.sql.SQLException e){processError.logError("validateUser Invalue user" + e.getMessage()); enable = false;}
catch(java.io.FileNotFoundException e){processError.logError("validate User error" + e.getMessage());}
catch(java.io.IOException e){processError.logError("evalidateUser rror File Error " + e.getMessage());}
catch(java.lang.NullPointerException e){processError.logError("validateUser error Null Pointer " + e.getMessage());}

You are not using the server's built in JDBC Connection pooling, so there is no special WebServer configuration needed to connect to a database.
If in the other hand, you want to use the built in connection pooling, then refer to this page to see how to create a connection pool
http://docs.sun.com/source/817-1831-10/agjava.html#wp1085593
Samples on how to configure and use JDBC connection pooling can be found in the sample apps

JDK 1.4.2 with Sun One Web Server 6.0 SP5?

In the release notes for 6.0 sp5 I see that latest supported JDK is 1.4.1_01. But I thought versions 1.4.0 and 1.4.1 are considered by Sun to have reached their end of life and now 1.4.2 is the supported one. So, is JDK 1.4.2 (or will it be) supported for 6.0 sp5?
Any experiences?

Specifically, what are you looking for?
Does it work? Yes, I've been able to use 1.4.2 with 6.0. Just need to set the StackGuard as per the Release Notes for earlier (pre-1.4.2) J2SE's.

Sslext NOt working Sun ONE Web Server 6.0?

Hi,
I have implemented the sslext tag for dynamic switching of http to https.
I am using ATG Dynamo Server ONLY in the Development Env. (using the default Web Server of ATG) for testing this and sslext tag works fine using the Plug-In of struts which is in sslext.jar.
but in producation the ATG Dynamo Server 6.0 is configured with Sun ONE Web Server 6.0, as forwarding request throught the Web Server to the App Server.
But here sslext stop working?? any guss why?
Sun ONE Server 6.0 is configured with ATG Dynamo Server 6.0 as Connection Module.
There are three ways a Connection Module can handle requests for files whose MIME type is text/html.
1)You can choose to have the files served by the Sun ONE Web Server,
2)by the Dynamo server,
3)or by the Sun ONE Web Server (but also send requests to Dynamo for logging).
we select the 3rd option.
any Guess why this is happening???
regards
DJ

Since removing the log settings from magnus.conf failed to fix the problem, the log settings are probably not the source of the problem.
Did anything else - e.g. ColdFusion configuration changes - occur at about the same time you changed the log settings?

Sun ONE Web Server & Remote User field

Hi,
I look for a tip to my Sun ONE Web Server 6.1 SP2 configuration.
I have:
- OS: Sun Solaris 8
- Apache 1.3 (listen port :80)
- Sun ONE Web Server 6.1 SP2 (listen port :81)
- Weblogic 8.1 SP4 (listen port :8001)
The 3 applications are in the same server.
My first configuration works:
- Apache works with basic authentification by password file (generate with htpasswd) and communicates with Weblogic
- Weblogic listens http requests and work with the remote user id (use method HttpServletRequest.getRemoteUser())
My second configuration doesn't work:
- Apache works with basic authentification by password file (generate with htpasswd) + reverse proxy mode (use VirtuaHost) and communicates with Sun ONE Web Server
- Sun ONE Web Server works with no authentification mode and communicates with Weblogic
- Weblogic listens http requests and works with the remote user id (use method HttpServletRequest.getRemoteUser())
The HttpServletRequest.getRemoteUser() returns null in my second configuration.
How I can configure my Sun ONE Web Server to foward the remote user id ?
Thank you.
Christophe.

Can you send your obj.conf?
I do not have a 6.1 Web Server installed, by guess work try
NameTrans fn="redirect" from="/index.html" url="/"
Also remove find-index or any such SAFs if you have in your obj.conf
PathCheck fn="find-index" index-names="index.html,home.html,index.jsp"Why do you need this?

Sun One Web Server 6.1 SP4 crashes when filters are built with CC ver. 5.6

Hi All
We are using NSAPI interfaces to develop the filter for Sun ONE 6.1 SP4 Web Server. Filter was working perfectly fine when it was built using Sun WorkShop 6.0, CC Compiler ver 5.2.
After we upgarded to Sun WorkShop 9.0, CC Compiler ver. 5.6, it no longer works. The web server crashes with Core. Please see the snippet below. There was however no change of code required for the upgrade.
Please let me know if some specific compiler/linker flags has to be used for building filters with CC Compiler ver. 5.6.

I could trace down the problem to the fact that if I don't use the map file (which is passed to the linker using -M mapfile), the plugin works perfectly fine. Further to this if I comment out the local part of the mapfile, it starts working.
mapfile :
NSAPIPlugin.so {
global:
symbol1;
symbol2;
symbol3;
# local:
Is there is any specific linker flag that I have to pass along with -M mapfile with the sun studio 9. What are possibe consequencies if I go ahead with this workaround of commenting out the local directive.

Integration of Sun One Web Server 6.0 with Sun One App Server 7.0

Is it possible to integrate Sun One Web Server 6.0 with the Sun One App Server 7.0??
Sun One App Server 7.0 comes with the in-built HTTP listener. But we want to know if there is a way by which we can use the Sun One Web Server 6.0 with the App Server 7.0 and not the in-bulit HTTP listener?

As suggested by you, I have used Sun ONE Application Server 7's plugin to connect the Sun ONE Web Server 6.0 with Sun ONE Application Server 7 as per the information given in Sun ONE Application Server 7 Administrator's Guide.
I have added the plugin package to the webserver and added the following into the magnus.conf:
Init fn="load-modules" shlib="C:/iPlanet/Servers/plugins/passthrough/passthrough.dll" funcs="init-passthrough,auth-passthrough,check-passthrough,service-passthrough" NativeThread="no"
Init fn="init-passthrough"
and to the obj.conf
NameTrans fn="assign-name" from="(/A2P2Test|/A2P2Test/*)" name="passthrough"
<Object name="passthrough">
ObjectType fn="force-type" type="magnus-internal/passthrough"
Service type="magnus-internal/passthrough" fn="service-passthrough" servers="http://<application server http listener>"
Error reason="Bad Gateway" fn="send-error" uri="$docroot/badgateway.html"
</Object>
The webserver starts up without any errors but never forwards any requests what might I be doing wrong?

I have been stumped by this error. I have tried several different ways to install this software but I always get the same error. I believe that I have the latest version of the Sun One Web Server and I received no error notifications when I installed it! Any help would be apeciated!
Thanks!!!!!

I think this might occur if you don't have the patch for SunAlert 46042 installed. There's more information on this critical Solaris security vulnerability, which was reported back in 2002, at http://sunsolve.central.sun.com/search/document.do?assetkey=1-26-46042-1
Can you run the following command to check if you have patch 109326-09 installed and let us know the result?showrev -p | grep 109326If you don't have 109326-09 or higher installed, you should install it as soon as possible. You can follow the link from the SunAlert. Better yet, install the latest Solaris 8 recommended patch cluster from http://sunsolve.sun.com/pub-cgi/show.pl?target=patches/patch-access to make sure your system is fully patched and up to date.

Problem with maxprocs 1 on Sun One Web server 6.1

I am using sun one web server on Unix with maxprocs set to 3.
This means that there are 3 jvms running my application under 1 instance. However I have certain components like an application cache that I would like to share between these 3 processes.
Additionally is there a way to configure the server so that requests from 1 session are served by 1 process only.
I am really stuck here. Have searched in all the documentation, but in vain. Would really help if some one of the Sun Developers could answer this.
Thanks

Elving,
It is great to hear that there is no predefined limit on number of sessions but if that's the case why the webserver always starts with 1000 allowed by default. Are there any potential performance reasons behind it?
I have your link open in my browser for a few days now as a reference because I am experimenting with different Session Managers. I am trying to find a solution for BheegaChicken to be able to accomodate several thousand simultaneous sessions for his application.
We use V6.0SP2 and SP6 and for BheegaChicken's app specifically V6.1SP2...
I have spent some time in the past looking for the answers how to handle higher then 1000 sessions capacity on one instance and that was even before V6.1 was out. I have found the following reco that talks about optimal performance for sites using threads:
http://docs.sun.com/source/816-5690-10/perf6.htm#17580

Multi-Process Mode
You can configure the server to handle requests using multiple processes with multiple threads in each process. This flexibility provides optimal performance for sites using threads, and also provides backward compatibility to sites running legacy applications that are not ready to run in a threaded environment. Because applications on Windows NT generally already take advantage of multi-thread considerations, this feature applies to Unix/Linux platforms.
The advantage of multiple processes is that legacy applications that are not thread-aware or thread safe can be run more effectively in iPlanet Web Server. However, because all the Netscape/iPlanet extensions are built to support a single-process threaded environment, they may not run in the multi-process mode, and the Search plug-ins will fail on startup if the server is in multi-process mode.
In the multi-process mode, the server spawns multiple server processes at startup. Each process contains one or more threads (depending on the configuration) which receive incoming requests. Since each process is completely independent, each one has its own copies of global variables, caches, and other resources. Using multiple processes requires more resources from your system. Also, if you try to install an application which requires shared state, it has to synchronize that state across multiple processes. NSAPI provides no helper functions for implementing cross-process synchronization.
If you are not running any NSAPI in your server, you should use the default settings: one process and many threads. If you are running an application which is not scalable in a threaded environment, you should use a few processes and many threads, for example, 4 or 8 processes and 128 or 512 threads per process.
MaxProcs (Unix/Linux)
Use this directive to set your Unix/Linux server in multi-process mode, which may allow for higher scalability on multi-processor machines. If you set the value to less than 1, it will be ignored and the default value of 1 will be used.
Tuning
You can set the value for MaxProcs by:
Editing the MaxProcs parameter in magnus.conf
Setting or changing the MaxProcs value in the Magnus Editor of the Server Manager
Note You will receive duplicate startup messages when running your server in MaxProcs mode.

If it is not relevant anymore please explane.
I am still interested to understand which of the SessionManagers is recommended by Sun to have optimal performance for sites with high number of sessions and using threads. It is not really obvious from http://docs.sun.com/source/817-6251/pwasessn.html. On top of this that's documented just for V6.1. What about V6.0?
Thank you very much for your cooperation!
