Configurate Oracle 9.0.2 with Tomcat jakarta-tomcat-5.5.7

Hi all,
After installing Oracle 9.0.2 as a standalone db on my PC, some Java and Jsp classes don't run properly. I get the following error msg:
java.lang.NoClassDefFoundError: javax/xml/transform/Source
I think it may be a problem with path. For Java programs, I now use a bat file to set path to ignore "C:\oracle\ora92\bin;C:\Program Files\Oracle\jre\1.3.1\bin;C:\Program Files\Oracle\jre\1.1.8\bin;" in system's path like this:
set PATH_BAK=%PATH%
set Path=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\Program Files\Executive Software\Diskeeper\;"C:\Program Files\Symantec\Norton Ghost 2003\";C:\j2sdk1.4.2_06\bin;C:\j2sdk1.4.2_06\jre\lib\ext
java %1
SET PATH=%PATH_BAK%
The Java classes run properly with the bat file now. But would there be some better solutions? And how can I run the JSP programs again?
Really appreciate for any suggestion / help. Thanks very much in advance.

The oracle\jre\1.3.1\bin is installed, and used by component of the Oracle Database that are built with Java.
This would be things like the installer, the network config manager, etc.
If you remove it, then chances are these things will still work, but they'll be running on an unknown version of Java (for them anyway).
But give it a go. If you find you have problems running the installer, or the network manager later on, then you can always put the Oracle JRE back into the path to launch the utility you need.
I tend to change mine around as you've done by setting some environment variables ORACLE_JRE=... and then switch the order of them in the PATH as I need. It's sort of self documenting in that way.

    Hi all,
    I have further located the problem -- if remove from path "C:\Program Files\Oracle\jre\1.3.1\bin", the Java classes works again.
    But what problem would occur if it is removed from path permanently? Any suggestion? Thanks very much.

  • Old Oracle Session with Tomcat is not kiiling automatically

    Hi,
    I am facing a problem of increasing inactive oracle sessions with tomcat, Old Oracle sessions with tomcat are visible with new one.
    if somebaody did not restarted tomcat gracefully, then does Oracle keep the session connected or is there any way that whenever any one restarted tomcat abnormally, Oracle session can be killed.
    I had restart the database to kill session.

    Could you please tell me that where do i set this parameter in parameter file or sql net file and what is the recommended value, do you have any document on this.
    Another thing tomcat is in other server machine and my database is in different server machine, killing process in tomcat server machine manually may not kill linux process on oracle database machine and therefore oracle sessions are still there.
    Is it possible?

  • JSP: work with TomCat 5.5.9 and NOT work with TomCat 6.0.16

    Hi all,
    I'm Antony and I have a problem with a .JSP page of my server.
    In my server there are 2 users: "u1" and "u2"; there are 2 TomCat, version 5.5.9 and version 6.0.16. There is Apache WebServer version 2. The 2 TomCat servers have the same configuration files: server.xml and web.xml (in the dir /conf of the main server's root). They not work simultaneously.
    When the user "root" launch the TomCat 5.5.9 all work fine: the server will show correctly the JSP pages of "u1" and the pages of "u2".
    When the user "root" launch the TomCat 6.0.16 the JSP pages of "u1" work fine but the JSP pages of "u2" not work: it seems that there are problems with the path where the server want to search the pages of u2.
    In the server.xml there is this code (for the handle of u2's site):
    <Host name="u2site.com" appBase="/home/u2/public_html/">
      <Alias>www.u2site.com</Alias>
      <Context path="" reloadable="false" docBase="/home/u2/public_html/" debug="0"/>
              <Context path="/manager" debug="0" privileged="true"
                  docBase="/usr/local/jakarta/tomcat/server/webapps/manager">
              </Context>
    </Host>and this code (for the u1's site)
    <Host name="u1site.com" appBase="/home/u1/public_html/">
      <Context path="" reloadable="false" docBase="/home/u1/public_html" debug="1"/>
              <Context path="/manager" debug="0" privileged="true"
                  docBase="/usr/local/jakarta/tomcat/server/webapps/manager">
              </Context>
    </Host>The problems with the JSP pages of u2 are one of the following:
    org.apache.jasper.JasperException: /login2.jsp(4,0) The value for the useBean class attribute com.u2.beans.access.Autenticator is invalid.and this one that appear with the pages that have the inclusion of another JSP page
    /u2page.jsp(3,0) File "/../support/_formatting.jsp" not foundI think that the TomCat know how to find the page that the browser request to Apache WebServer (and that the webserver request to Tomcat by the connector) 'cause for pages that haven't inclusion or call to method in packages all work fine...but the TomCat have problems to locate the pages included or the method located in a JAR (the jars are located in WEB-INF/lib/ of the u2's site).
    How I can resolve this problem with TomCat 6.0.16? I repeat that with TomCat 5.5.9 all work fine...same configuration!
    Any ideas?
    Thank you very much,
    Antony.

    Hi stevejluke, 'cause in the page "/supporto/_formatting.jsp" there are only the definition of some variables it's normal that the output at the browser it's a blank page.
    The problem it's that Tomcat 6.0.16 cannot know how "navigate" the pages beginning from one...it know where is the "x.jsp" page requested directly by Apache WebServer, where is "y.jsp" request directly by Apache, where is "z.jsp" requested directly by Apache but if "x.jsp" request, includes, "y.jsp" Tomcat cannot know where "y.jsp" is located. There is some file where I can "say" this to Tomcat?
    The page "/mostre/elenco_mostre.jsp" includes directly the "/supporto/_formatting.jsp".
    Another thing: in /mostre/elenco_mostre.jsp there is an inclusion directive for /supporto/_formatting.jsp that is so:
    <%@ include file="../supporto/_formatting.jsp"%>you can see that the included file is "../supporto/_formatting.jsp" and NOT "/../supporto/_formatting.jsp"...the "/" at the begin of the path is included by Tomcat!
    In the catalina.out there are this lines, when the page is called:
    Jul 6, 2008 3:15:00 AM org.apache.catalina.core.StandardWrapperValve invoke
    SEVERE: Servlet.service() for servlet jsp threw exception
    org.apache.jasper.JasperException: /elenco_mostre.jsp(3,0) File "/../supporto/_formatting.jsp" not found

  • Problem with Tomcat 6

    Hi guys,
    I am with a very strange problem with my job here.
    We had a server working with Tomcat 5 and it didn't have problem, but wanted to changed to Tomcat 6.
    So.. we changed and it ran normal and well.
    The problem is when we stress the server with one or more big queries, execptions is showed that didn't show with Tomcat 5:
    java.lang.Exception: [Microsoft][SQLServer 2000 Driver for JDBC]Object has been closed
    Using SQL Server 2000
    java.lang.Exception: The connection is closed.
    Using SQL Server 2005
    java.lang.Exception: I/O Error: socket closed.
    Using SQL Server 2005 with jTDS driver
    It happens with Oracle too.
    Can anybody help me?
    Thanks!

  • Tutorial on using client cert with Tomcat 5

    Hello,
    I'm looking for a tutorial on using client-cert method with tomcat 5.0.28 with jsp pages.
    I want to generate my own certs and keys.
    Is there anything like this on the web ?
    Thanks

    Maybe you could try searching the Tomcat mail archives or post your question to one of their mailing lists.

  • Tomcat 5.5 issues, has anyone got JSF working with tomcat 5.5 yet?

    Hi,
    Firstly I'm wondering if anyone has got JSF 1.1 working with tomcat 5.5 yet.
    I'm trying to move from tomcat 5.0.25 to 5.5.4 and my JSF webapps have not liked the move at all.
    The classpath doesn't seem to be a problem as I have all the .jars that are required in the classpath of tomcat just like before.
    I see the error log in stdout.log (catalina.out on linux) have been reduced to only show the precise error. Or at least is seems at lot easier to read.
    My error is simply
    SEVERE: Error listenerStart
    SEVERE: Context startup failed due to previous errors
    I reverted back to using the examples provided like jsf-guessNumber and the car-demo but neither of these will start-up.
    This issue seems to have occurred to lots of other people previously but I couldn't find a particular fix or direct compatability issue with tomcat.
    Has anyone encountered this before?

    Back again,
    Allright well after a little thought I concluded that this issue had to be some to do with the classpath and the changes between the two tomcat versions.
    I had a look at
    http://jakarta.apache.org/tomcat/tomcat-5.5-doc/RELEASE-NOTES.txt
    and noticed that tomcat 5.5 leaves out some important .jar as they are only needed for java 1.4.
    -------------------- EXTRACT ------------------------
    Installing the compatibility package will add the following to the list, which are
    needed when running on J2SE 1.4:
    * jmx.jar (Java Management Extensions API 1.2 or later)
    * xercesImpl.jar (Xerces XML Parser, version 2.6.2 or later)
    --------------------END EXTRACT ------------------------
    Therefore I tried putting xercexImpl.jar back onto the tomcat classpath and JSF works once again.
    Ah what a relief.

  • Has anyone tested ResilientDemo with Tomcat 5.5.9?

    I have followed the Technical Note #007.htm to the letter and still could not get the demo working. Here is what I did:
    1. Start Tomcat
    2. Modify ant.cmd to configure AXIS_HOME and ANT_HOME. (I am using ant-1.6.5 and axis-1_2_1)
    3. Copy the class directory to TOMCAT_HOME/webapps/axis/WEB-INF (I create the axis/WEB-INF directory)
    4. run ant.cmd.
    Here is the error I got:
    Buildfile: build.xml

    javax.mail.internet.MimeMultipart). Attachment support is disabled.

    Has anyone tested the ResilientDemo with Tomcat 5.5.9? Where can I find the missing classes? Thanks.

    They haven't removed these classes (DataHandelr & MimeMultipart) bacause I have them inside activation.jar and mail.jar, which are located at ${tomcat.home}\webapps\axis\WEB-INF\lib, and I get the same error with another example. Where is the trouble? I extracted activation.jar from jaf-1_0_2-upd2.zip, mail.jar from the javamail-1_4.zip (I think both are the latest releases) and use Tomcat 5.5.12. Thanks.

  • Problems configuring XSQL with Tomcat

    Having a lot of trouble getting this to work with tomcat standalone, apache with tomcat, and even apache with resin. (I have successfully gotten this to work with resin as both web and appserver.)
    I have tried to be meticulous in following the directions, but one thing that is throwing me is that I can't find the web.xml file in my xdk distribution (neither in xdk8i nor xdk9i); I've attempted to create the .xsql extension-to-servlet mapping myself in Tomcat's web.xml file, but maybe I got this wrong.
    The main symptom is that my xsql pages are basically being returned to me in the browser. Any help would be appreciated.

    Bacically you need to create yourself, and here is an example:

  • Orcale with Tomcat

    Hi All,
    I am new to Oracle. My application server is Tomcat. But I came to know Oracle is working with its server. Can we integrate Oracle with Tomcat server...? Please come up with a solution. Its very urgent.Any reply will be appreciated..

    Oracle has an integrated PL/SQL appliction server inside the core database. Simplistically, you can call a PL/SQL stored procedure (with parameters) from your web browser. You can upload files directly by calling a PL/SQL stored procedure.
    Even better, with Oracle 10G you do not need a web server like Apache. The httpd daemon resides inside the database.
    This means less software layers. Less hardware needed (like a separate application server platform). Less moving parts that results in less complexity, fewer bugs and exponentially faster development times. (and no, the application server does not scale the data tier - so scalability is also not an issue)
    Or you can use a web-based IDE and run-time system from Oracle using this technology, called Oracle Application Express. It is free. It supports Oracle 9.2 and 10G. It can run on anything from Oracle XE (Express Edition) to Oracle Enterprise RAC (Real Application Clusters).
    I can pretty much guarantee that not knowing Oracle, you can and likely will make a mess of using Oracle from an application tier like Tomcat. There are numerous issues, especially around bind variables and locking and maximizing SQL (and PL/SQL) and minimizing app tier data processing code. I have lost count of how many poorly design and even poorer performing "high-end" commercial web-based applications I have run into for Oracle. Some of these costing serious money (and utterly lacking in peformance and scalability, requiring me to implement hacks on the back-end to work around their flaws)
    Fact: to effectively use Oracle (in any architecture), you need somewhere someone that has solid Oracle experience to ensure that the fundamental Oracle principles are adhered to.
    Using something like Oracle Application Express does a lot of these for you automatically. It handles state, optimistic locking, bind variables, etc. Allowing the developer to simply focus on the web application page design and the processing flow of the application. Very little PL/SQL or Oracle expertise required compared to using another app tier like Tomcat.
    I would suggest that you give serious consideration to using Oracle's Application Express or moving your app tier into PL./SQL (and out of JSP, Java, PHP, Perl, etc).

  • Oracle Workflow 2.6 with Oracle 8.1.7 for linux

    Is Oracle Workflow Server 2.6 available for Linux as a
    standalone product against an Oracle 8.1.7 database?
    Oracle Workflow does not seem to be included in the Integration
    Server option with the 8.1.7 installation.
    I've only found the Oracle Workflow Server included with the 9i
    database. Will this work with 8.1.7 as well or does it require
    9i db?
    Thanks in advance for your help,

  • Oracle 10g R2 installation with ASM+RAC

    Gurus,
    Need some suggestuon on Oracle 10g R2 installation with ASM and RAC option.
    We have found many documents on the Oracle, HP, HP-Oracle CTC and third party web sites, but nothing that is specific to this particular combination of separate
    ORACLE_HOMEs, ASM and 10g RAC CRS. It is unclear for me from the documentation how this combination of ASM and 10.2g RAC may best be installed.
    The high level steps i got after reading lot of docs as follows - but i am not sure whether these are correct or not. if they are correct, can any one share their experience/notes please?
    1) Install CRS
    2) Install RDBMS for ASM HOME - create separater oracle home for ASM instance using OUI
    3) Install RDBMS for RAC Database Home - create separater oracle home for RAC database using OUI
    4) Create ASM database using DBCA -
    5) Use dbca to create database.

    Oracle provides 'paint by numbers' tutorials called 'Oracle By Example'. (Go to OTN, check under the Training tab)
    They have one for a Windows based ASM/RAC that you might want to review. Not your specific environment, but the steps will be dag-nabbed close.
    I recommend walking the path (http://otn.oracle.com >> training:OBE >> Database 10g Release 1:VMWare:Installation

  • How to create a new Oracle OSB project automaticaly with script without IDE

    Hello,
    I want to create automatically an "Oracle service bus project" and an "Oracle service bus configuration project" with scripts (ANT or Maven or ...) without using IDE, without using workshop or Eclipse. I want to create automatically (ANT or Maven) just a skeleton of an OSB project witch i can use after in workshop.
    I want to create 1 "Oracle service bus configuration project" with many "Oracle service bus project" automatically (ANT or Maven or scripts) witch i can use after in workshop. How to create a new Oracle OSB project automaticaly with script without IDE ? How can i do this ?
    I'm using Oracle service bus 10.3.1
    Thank you for your help.

    Thank you for your response,
    I do not want to just create the services (proxy services and business services) but I want to create a template for 40 OSB project with the same scripts ANT/Maven.
    Template="Oracle service bus configuration project" + "Oracle service bus project" + services of 40 OSB projects
    The goal is that I have more than 40 projects to create and just the name of the projects that changes (when I say the name of the project ie the name of the OSB project, the name of proxy services and the name of business services ).
    So I want to give my script (ANT/Maven) the name of 40 OSB project and the script must generate the skeleton of the 40 projects at once time and after generation of skeleton of the 40 project, I will import them in the workshop to add manually mapping and routing and other things that differs from one project to another.
    So i want to generate automatically a skeletons of 40 OSB projects using a script (ANT / Maven) and I give to the script juste the names of the 40 projects.
    I want to create a "Oracle service bus configuration project" and "Oracle service bus project" automatically of 40 OSB projects (ANT or Maven or scripts) witch i can use after in workshop.
    I want to create one 'template' of all 40 projects in the same time, with the same directory structure (Transforlation, Business services, proxy services, WSDL .....) and all 40 project have the same transport, just the names of projects and services witch changes and i can give to the script all names of projects and services and i can give also all WSDL.

    Tarik
