JSP engine and licenses

We currently have weblogic running both our JSPs and EJBs on 2 clustered servers, with apache web servers on some other machines.
We are considering moving the JSP layer onto the same machines as the web servers, perhaps using tomcat.
Is this practical/sensible? and if so will we need any more WL licenses? im assuming we will have to put some of the WL classes on the web servers although we wont be running WL there.
Thanks,
James

Is JSP Engine compatible and up to date?

I've been looking for a way to compile jsps from the command line so they can be verified during our automated ant builds rather than producing compile errors during testing.
I noticed the jsp engine on the downloads page and it seems to do what I want. However, it seems pretty old. Is it compatible with the lastest versions of tomcat and oc4j?

If you want a media server you're proably better of buying a Mac that doesn't have a screen like the Mac mini.

Oracle JSP engine on Apache

Hi,
We have Apache Web server 1.3.9 and Jserv 1.1b3. On top of this, we have installed Oracle JSP engine. We have put the names of all the required jar files and directories in jserv.properties file. But, when we try to access any jsp files from a browser we are getting following error:
Request URI: /test.jsp
Exception:
oracle.jsp.provider.JspCompileException:
Errors compiling: d:\demos\apache\htdocs\_pages\test.java
Package javax.servlet.jsp not found in import. import javax.servlet.jsp.*;
Any idea why this error is happening.
Thanks in advance,

Apache JServ implements Servlet 2.0 -- this class library doesn't contain the JSP interface classes. The JSP interface classes are contained in the JSWDK 1.0 (or greater) available from Sun. Download and configure Apache to use this class library AFTER the reference to the servlet 2.0 class library. For more information please check out the Documentation section for JSPs on technet. It contains specific information on configuring/installing for Apache.

Very basic questions about JSP server and plug-in.

Hi all,
I am wondering what are other ways to make use of the JSP script on a server running normal Apache without changing it to Tomcat. Is there a plug-in version of JSP for Apache that will enable JSP? I am looking for something like PHP plug-in, which is quite generic. They even have a php.exe that OHTTP (a great shareware Win32 web server) can call to run PHP. Is there such thing along this line with JSP on Win32 or Linux? Thanks!

You need a jsp/servlet engine, and in effect, Tomcat is the "plug-in" you described. Tomcat has basic web server functionality built in, so it can run stand-alone, but it's most commonly used with a robust web server like Apache. You don't have to "change it" to Tomcat - you just configure Apache to forward specific urls (anything ending in *.jsp, for example) to Tomcat.

JDeveloper 3.1 JSP Engine Run-Time error - "NLSFormat undefined"

hi,
I have a JSP/Bean page running through JDeveloper 3.1
It has the "EditForm" bean with (among other fields) a date field in it.
<jsp:useBean class="....EditForm" id = "f1">
<%
f1.initialize(.....);
f1.setFormAction(.....);
f1.addHiddenField("executeQuery","true");
f1.addDateField("List Docs failed on","ReportDate1",null,null,null,null);
f1.addSubmitButton("submit","Submit");
f1.render();
%>
Scenario:
When the JSP page is generated and i enter a date value like (08-SEP-00) and click on the "Submit" button, i get the following error.
Error Name: "Run-Time Error: NLSformat is undefined"
The relevant generated HTML line in the page which has the NLSformat in itis as follows:
<INPUT TYPE="TEXT" NAME="ReportDate1" onchange="this.value = datecheck(this.value,NLSformat);checkForError(this,distribute)"
Is NLSformat something to do with the datefield ? - I was reading thru the OTN docs, does NLSformat need to set up as a startup parameter in the 8i instance? - is that the way the JSP engine picks up the value/definition of the NLSformat variable? - I would really appreciate some replies on this issue.
Thanks,
Balaji

Hello,
Even I am facing the same problem on windows 98. When I try to run my database servlet from Jdeveloper3.0 nothing happens.
In browser .../.../webapprunner.html url gives similar error like the one Flavio is getting. Which version of Jdeveloper can I use on Win 98?

Webserver/jsp engine call into weblogic ejb container

Which one of these architectures would give the best performance.
          First architecture:
          3 boxes -
          1st box - webserver(IIS or IPlaner) with a JSP engine. (The JSP's
          produce dynamic content.)
          2nd box - weblogic 5.1 hosting EJB's
          3rd box - Oracle or DB2
          The 1st box is used to server up dynamic contect. The JSP's make dynamic
          contect from calls into the EJB container in the 2nd box. The EJB's then
          calls the DB in the 3rd box.
          2nd architecture:
          3 boxes-
          1st box - webserver with weblogic plug-ins for IIS or IPlanet
          2nd box - weblogic 5.1 - hosting JSP pages and EJBs
          3rd box - Oracle or DB2
          The 1st box's webserver just receives the request to JSPs and lets the
          plug-in find the appropriate weblogic instance. The JSPs that are processed
          on the 2nd box make calls into the EJB container on the 2nd box. The EJBs
          then make calls to the DB on the 3rd box.
          thanks

Upgrading Oracle JSP Engine to 1.1.2

I'm trying to upgrade Oracle JSP Engine from 1.1.0.0.0 (which comes with Oracle 8.1.7) to 1.1.2.
I've downloaded new version from OTN and I used loadjava to update classes in the database. Now I'm trying to use ncomp to natively compile classes (like I've read in the Releases Notes) but I'm getting:
error in: FindClassesToNcomp :java.sql.SQLException: ORA-29532: Java call terminated by uncaught Java exception: java.sql.SQLException: java.sql.SQLException: failed to produce status report because of: java.sql.SQLException: got error at insert into jaccelerator$status oracle.jdbc.driver.OracleSQLException: ORA-01401: inserted value too large for column
ORA-06512: at "SYS.JACCELERATOR___FIND_CLASS_LIST", line 0
ORA-06512: at "SYS.JACCELERATOR_FIND_CLASS_LIST", line 1
ORA-06512: at line 1
Any idea??
Thanks in advance.

Welcome to the discussions!
Adding RAM is the quickest and cheapest way to get a performance boost. As mentioned, the apps you use are not universal and will run through the Rosetta translator which is a rather RAM intensive operation.
My suggestion is to get at least 1GB and if it is not too much of a stretch to get 2GB. RAM is relatively inexpensive now and the benefits will be seen immediately.

My JSP engine won't load the new source from my page

My JSP engine won't load the new source from my page, even know I saved it, and I restarted apache, and resaved the files again, no dice! It must be running off of cash, it's not in my browser cash I cleared it out too, what else can I do?

Tomcat checks to see if the JSP has changed since it was last compiled with you request that page... So, if the file is updated, it should recompile it. Are you sure that when you update the page, you're updating the same copy of the page? (the location defined in the server.xml file)

Engine and NSMAdmin client refuse to install/work on DC

Hi,
I have a strange problem setting up Storage Manager 3.0.3 at a customer.
The customer has a server 2008 R2 64 bit DC especially for IDM purposes (IDM Remote Loader, Exchange tools for creating mailboxes and also intended to be the Storage Manager server for the creation of home directories after adding a user to AD by the IDM AD driver).
First i installed the Test environment. I tried to install Storage manage Engine and Admin console on the DC with a user that is member of domain admins, enterprise admins, schema admins.. the lot.
When i tried to logon to the Admin Console, the console gives me an error: authentication failed due to logon rights not being granted to the account. The admin console does NOT start with the rest of the setup and the user does NOT become part of the NSMAdmins group (the group is never created).
Well.. after a week of trying, i blamed the DC and installed in on a member server. It went well, the NSMadmin tool logged in correctly and the setup was continued. NSMAdmin group was created and everybody was happy.
This week i installed the QA environment. (Those are new clean servers) and guess what. EXACTLY the same problem. I did some additional testing by installing the engine and admin console on a member server + DC and tried cross-connecting:
- Connect from NSMAdmin client on member server to DC engine: Failed login, no Setup
- Connect from NSMAdmin client on DC to engine on member server: Failed login, no Setup
- Connect from NSMAdmin client on DC to engine on DC: Failed login, no Setup
- Connect from NSMAdmin client on member server to engine on member server: Success, install continues and asks for the license key etc.
All attempts where done:
- Using the same domain user
- Retried with a cleanly created domain admin user
- On server 2008 R2 64 bit (both DC as member server)
There is a clear relation to this topic:
http://forums.novell.com/novell/nove...ins-group.html
Can anyone tell me what's going on here. It seems that Storage Manager cannot be installed on a DC.

Hi,
> Can anyone tell me what's going on here. It seems that Storage Manager
> cannot be installed on a DC.
Do you have a forest with multiple domains?
Remember to specify the correct domain at logins and such, I remember
having some problems with that.. some things pointed to the wrong (root)
domain.
Our test environment has NSM on the the DC, in production we run NSM on
separate server.

How to keep the servlet java code the JSP engine generated?

Hello there!
          I am using some JSP in a web application, and would like to take a llok
          at the servlet java files th weblogic JSP engine generated.
          In my weblogic.properties file I have the following line:
          "# Set up WebLogic JSP properties
          weblogic.httpd.register.*.jsp=weblogic.servlet.JSPServlet
          weblogic.httpd.initArgs.*.jsp=\
          pageCheckSeconds=1,\
          compileCommand=F:/VisualCafeEE/bin/sj.exe,\
          workingDir=F:/weblogic/myserver/classfiles,\
          verbose=true,\
          keepgenerated=true"
          However, the only things I can find are the class files compiled from
          the servlet java files.
          Any suggestions?
          Thanks.
          Jeff.


Moerover, if you follow the example web.xml Weblogic provides
          (http://www.weblogic.com/docs51/classdocs/sample_web_xml.html), the parser
          would complaint big time.
          The <servlet> and <context-param> tags have to be switched.

Through the JSP Engine twice

I have XML file and XSL-file, the XSL files returns almost the same XML as before but with JSP-statements added. So when I write
transformer.transform(new StreamSource(�formO.xml�), new StreamResult(out));
the output is indeed an XML-file with <% ... %> statements in between. How do I parse this file again by the JSP-engine to replace the JSP-statements. Is it possible without using temporary files or something?
Greetings,
Raf

Well, I have a JSP-page that looks like this:
<%@ page contentType="text/xml" %>
<%@ page import="javax.xml.transform.TransformerFactory" %>
<%@ page import="javax.xml.transform.Transformer" %>
<%@ page import="javax.xml.transform.stream.StreamSource" %>
<%@ page import="javax.xml.transform.stream.StreamResult" %>
<%@ page import="javax.xml.transform.TransformerException" %>
<%@ page import="javax.xml.transform.TransformerConfigurationException" %>
<%@ page import="java.io.FileOutputStream" %>
<%
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(new StreamSource("DbToXml.xsl"));
transformer.transform(new StreamSource("formO.xml"), new StreamResult(out));
%>
And it returns the next code:
<?xml version="1.0" encoding="iso-8859-1" ?>
- <formO>
<titel>Subsidie aanvraag voor een sociaal woonproject</titel>
- <rubriek>
<titel>Rubriek 1: Algemene gegevens</titel>

Single DB Engine and multiple DB Instances approach

Hi Tech Arch gurus,
Need some advice from all of you. We are currently planning to install SAP training systems to latest versions.
We are getting recommendations to goahead with Dedicated host for Oracle Installation where we have Single DB Engine and multiple DB Instances for all different 7 SAP Servers (ECC6, CRM7, BI/NW7.3, SOLMAN7.01, SRM7, EP/NW7.3, PI7.1).
Certain things that need to be clarified before we go ahead with this:
1.     How complex/simple is this approach ?
2.     If there are some issues noticed in the future (Performance issues etc) in this landscape , how much effort will be required to migrate out a DB instance for an SAP product to another machine. We would be having both ABAP and Java stack for our systems.
3.     We would later plan for adding some more systems into the landscape like SAP MDM, SAP CE, SAP BPC etc. If we add all these systems with a single DB engine, would there be performance issues etc. (We are operating under assumption that underlying hardware of the DB engine will be powerful enough)
Can you please provide some expert guidance on this approach?
Your response would be much appreciated.
Thanks,
MD

As a consultant I never dared to do different from what SAP says in guides or notes, at least when it comes to PRD systems.
For QA and Test Systems, discussions might be needed with the customer, depending on how important these systems are,
and for sandboxes I already did some stuff, that will even scare some Oracle guys
As Stefan says, the technical setup is not that complicate at all.
But I never had to fight for a support call in a non-supported Environment, so I can't say.
I always decided to be on the safe side.
If you have your Oracle License directly from Oracle you might disscuss such special support issues with these guys.
The problem is: If you get a call, and the first level support guy from SAP spots the non-supported environment, it MIGHT be possible that you need to escalate and may be pay for the support, but I suppose they will not let your system die
May be some of the SAP moderator guys can throw a comment in on this.

Deploying the JSPs, Servlets and Java class files

Hello All,
I'm very new to the Oracle 9i AS. We are using Version 1.0.2.2.
How do we deploy the JSPs, Servlets, and Java class files (simple class files, not EJBs)?
plese give us the procedure and stpes how to deply or the links for the same.
Thanks,
Santhosh.

Hi
I guess u r running apache-jserv as servlet engine for your jsp and servlets. If its so, jsp files can be run without any additonal configuration by putting the jsp file under document root or any subdirectory and for running servlets u have to add classpath entries for your servlet in jserv.properties file.
To make sure that your servlet engine is working, try
http://servername:port/servlet/IsItWorking, if u get success msg that means servlet engine is working fine.
Hope this will help

Kumaran

Can the servlet/jsp engine be brought down

Hello,
          Can the servlet/jsp engine be scheduled for a "in-house patch" not affecting
          the EJB Container? That means the jsp/servlet engine is brought down.
          (HotDeploy is a development feature). Does any version of WebLogic provide
          any way to do this?
          It is a single VM and I suppose that this is not possible. Just thinking out
          loud!!
          Thanks
          Gaurav


Sorry, but there's no way to apply a hot-patch to the server. Good idea, but
          very tricky to implement!
          If you were using a cluster with session-replication, you can cycle the
          servers one at a time. The other servers will pick up where the
          downed-server was working. You can then apply the patch, and bring up the
          server again. Give it a few minutes (an hour to be safe!) to replicate from
          the running server, then cycle the other server safely.

What is the difference between Mobile Engine and MI?

hi all,
i want to know the difference between Mobile Engine and MI and also what are the main advantages included in MI instead of ME.

Hi Anusha,
ME had MicroITS as UI.
MI has JSP and AWT as UI programming.
From the above discussion its clear that JSP is the best option for programming.
PS: AWT was depricated by SUNMicro.
I just thought of sharing the history of MI.
just to share to you a "history" of mobile projects in SAP.
the current MI was actually a merged project from two mobile
projects - the old Mobile Engine and the unheard Mobile
Development Framework (MDF). when these projects were
restructured, the ME was extended with some functionalities
such as the SmartSync which was actually the replication
technology used in MDF. MDF client was based on C++ and
uses the CEDB as the database. it was not chosen to be
the client due to its platform-dependency. MDF was already
a working product when the restructuring happened. and there
were some client functionalities like xml based GUI and
metadata/logic definition that the current MI client doesn't
have.
Hope this is helpful.
Close the thread if your done with your clarification.
Cheers,
Karthick
