Plase advice

Hi,
You will need to add your class (com.raya.wireless.GeneralDownloadHook) to the CLASSPATH of the OC4J_Wireless instance.
The way I usually do this is:
1) Package your class in a .jar file and copy the .jar file to IAS_HOME\wireless\lib or any other convenient location
2) Add the .jar file as a library entry in IAS_HOME/j2ee/OC4J_Wireless/config/application.xml
For instance:
<library path="d:\oracle\ias902\wireless/lib/GeneralDownloadHook.jar"/>
Hope that helps,
Phil Darringer

How can I find the servlet class name from inside a ServletFilter?

Ive implemented a servlet filter, but need to discover the class name of any servlet class that gets executed.
Ive dug through the spec and cant seem to find any path to do this.
Seems the methods needed to do this have been deprecated. (for security reasons?)
Is there any way to write a ServletFilter to grab this info?
If not, is there any other way to capture every servlet execution in the container, time its execution, and log the class name along with the execution time?
(***WITHOUT*** requiring a classpath over ride of any container provider classes)
Any help is much appreciated. Been banging my head against this for some time now :(

request.getServletPath() returns the part of the URL which refers to the servlet. It isn't the classname of the servlet but it should be a reasonable surrogate. If you log that, then you could write some code which reads your web.xml and uses the servlet-mapping elements to convert it to servlet class names later.

Can't find registered ActiveX class - where's LabVIEW getting this from...?

Hi All
I'm trying to found out from where LabVIEW is getting this particular class from, since it isn't showing up when I open the Active X class browser, and yet somehow seems to be magically registered - I have some invoke nodes and it works fine. Why doesn't it show up in the class browser - shouldn't everything? Where else can I look for it? It's not a standard LV class, but a third party exe I installed. I know the class name (right clicking invoke, browse...). Ideas??

If you have a typelibrary you should probably use the regtlib.exe program instead. Some useful information might be found in this article. Of course if your library comes with an installer, the installer should have done this.

Where Can I Find the JSP Class files on OC4J (Orion server)

I am using Oracle J2EE Container (OC4J 1.0.2.2 aka Orion server) and I need to find the ".class" file generated for each JSP I created. I've looked under the "WEB-INF" directory under the "application" directory and the "persistence" directory under application-deployments and didn't find them. Any help would be appreciated. Thank you.

Tomcat config problem: jsp can't find a bean class

I've been working within a JSP/Javabeans/JDBC/MySQL architecture with Windows XP and Websphere. So far everything works perfectly. Now I need to get the same project and make it run with a Tomcat server.
I've already set the Tomcat server but its not working properly. I have a problem when a jsp tries to access any class inside my project's package.
For example, when I make the next call:
<jsp:useBean id="ctrl" class="myPack.myBean" scope="page"/>
I get an error saying:
Error: 500
Location: /myproj/login.jsp
Internal Servlet Error:
org.apache.jasper.JasperException: Unable to compile C:\Program Files\jakarta-tomcat-3.3.1\work\DEFAULT\myproj\login_1.java:64: Class myPack.myBean not found.
myPack.myBean ctrl = null;
^
I believe that my problem cames when setting the Tomcat environment. So far what I have done is:
* install j2sdk-1.3.1.03
* install jakarta-tomcat-3.3.1
* install mysql-max-3.23.51-win
* set the environment variable JAVA_HOME
* set the environment variable TOMCAT_HOME
* set the environment variable MYSQL_HOME
* add the %JAVA_HOME%\bin to the PATH
* create 'myproj' directory inside TOMCAT_HOME\webapps
* create into 'myproj' the subdirectory WEB-INF\classes and copy into it the jar file with my java classes (myPack.jar).
* copy into TOMCAT_HOME\lib\apps the JDBC driver for MySQL.
* copy my project files (jsp, html, images, etc.) and its structure into 'myproj' directory.
I haven't include anything into the CLASSPATH because so far I've read that Tomcat will automatically include all the classes that are inside the directories TOMCAT_HOME\myproj\WEB-INF\classes and TOMCAT_HOME\lib\apps.
I really don't have a clue about what I'm doing wrong. I'd apreciate if anyone can help me out with this one ;) ... I thank you in advance!

Hi, it's me again!.
Since nobody replied to me I'm replying myself :D
Ok, seriously is just to let you know that I have solved my problem and I would like to tell you how I solved it ... somebody might be doing the same mistake than I was doing and could found this helpful. I just forgot to mention that I was using Tomcat 3.3.
Well, first of all let me tell you that there was nothing wrong with the previous configuration that I post in my first message. Everything is ok except that in the TOMCAT_HOME\webapps\myproj\WEB-INF\classes directory I was putting my classes as a jar file, so I deleted it and instead I put the directory myPack with its unpacked class files. THIS SOLVED MY PROBLEM!!!
First I was trying to do some complicated things editing bat and xml files, but as a matter of fact I found it's quite simple. Furthermore, I was really surprised by the performance of Tomcat. I'm relly happy for that !! ;)
Hope it works for you,
Ernesto

Where Can I Find the JSP Class files on OC4J

Hi,
I am using OC4J 1.0.2.2 and I need to find the ".class" file generated for each JSP I created. I've looked under the "WEB-INF" directory under the "application" directory and the "persistence" directory under application-deployments and didn't find them. Any help would be appreciated. Thank you.

your jsp class are compiled in a file named namejsp.jsp.jspCache in the application-deployments\your app\persistence ...
but this file is not readable.
To hav your jsp like .class you have to delete your directory applications-deployments\your app
and open the file orion-web.xml and add the following:
development="true" under the tag jsp-cahce-dirctory
restart the server and then your jsp are created like .class

OBTAB = MARA
Get CUOBJ and KLART(class type)
KSSK   Table
OBJEK = INOB-CUOBJ
MAFID = 'O'
KLART = INOB-KLART
GET CLIENT
from KLAH with KSSK-CLIENT
Get class no.
Call the function module CLAF_CLASSIFICATION_OF_OBJECTS with the following input parameters

Where can I find IVI-C class compliant header files

I have installed the IVI files from IVI foundation website but the installation only includes all the files for IVI-COM not IVI-C.
I'm looking for the class compliant header files, IVIdmm.h, IVIscope.h, IVIspecana.h etc the ones in the include directory are all for COM, ie IVIdmmTypeLib.h
I asked the question on the IVI foundation forum and they said IVI-C has nothing to do with them it was being maintained by National Instruments.
So does NI have a download for these files?
Solved!
Go to Solution.

I think someone at the ivi foundation is lying but of course NI has them.

Where can I find documentation for class HttpJspBase?

Is it part of package javax.servlet.jsp?

Is it part of package javax.servlet.jsp?No. HttpJspBase is Tomcat specific, not part of the standard servlet or JSP packages. See http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jasper/docs/api/org/apache/jasper/runtime/HttpJspBase.html for documentation.

Can't find class because of try catch block ?!

Hello,
I'm using the JNI to use a java library from my c++ code.
JNI can't find the "Comverse10" class below, but when i put the try catch block in createMessage in comment, FindClass succeeds ?!
Unfortunatly i need the code inside the try block ;-)
I tried a few things, but none of them worked:
- let createMessage throw the exception (public void createMessage throws ElementAlreadyExistsException ), so there isn't a try catch block in createMessage => result: the same
- make a "wrapper" class Comverse that has a Comverse10 object as attribute and just calls the corresponding Comverse10.function. Result: Comvers could be found, but not constructed (NewObject failed).
Can someone tell me what is going on ?!
Thank you,
Pieter.

public class Comverse10 {
MultimediaMessage message;
/** Creates a new instance of Comverse10 */
public Comverse10() {

text1.setColor(Color.blue);
SimpleSlide slide1 = new SimpleSlide();

I would guess that the real problem is that that the
exception you are catching is not in the class path
that you are defining.Thanks jschell, that was indeed the case.
I don't have the docs, but I would guess that
FindClass() only returns null if an exception is
thrown. And you are not checking for the exception.
Which would tell you the problem.Ok, i'll remember that. But what with exceptions thrown in my java code, the documents say
// jthrowable ExceptionOccurred(JNIEnv *env);
// Determines if an exception is being thrown. The exception stays being thrown until either the native code calls ExceptionClear(), or the Java code handles the exception
so, what if the java code throws an exception and catches it, will i be able to see that in my c++ code with ExceptionOccurred ?
or
should the java method be declared to throw the exception (and not catch it inside the method)
Again, thank you for your help, it's greatly appreciated !

Can't find "Delegate Class Name" for JDBC Helper Service

Hi,
I downloaded WLServer 6.1 with sp1 and WLPortal 4.0, installed them on Solaris 7 using default DB cloudscape -- everything was fine. Now, I'm trying to configure database to Oracle 8.1.7.
In "Configure the JDBC Helper Service" section of document "Configuring WebLogic Portal for Oracle Databases" (http://e-docs.bea.com/wlp/docs40/deploygd/oraclnew.htm), step 2 requires to enter value of "com.bea.p13n.util.jdbc.internal.OracleJDriverJdbcHelperDelegate" to "Delegate Class Name". But, I can't find this "Delegate Class Name" variable. The available varialbles on the Configuration tab on my screen are: Maximum Number of Retries, Maximum Wait Time (milliseconds), Use CLOBs for Read?, Use CLOBs for Write?. And the Configuration tab is the only available tag for JDBC Helper Service. Did I download a different version from other people? I downloaded it within 3 months.
Can anyone help?
Thanks in advance,
Jane

Thanks Steve.
I had my own jndi.properties file that's why it was working with ejb bean I created in the AM and not with the sdo web service.
I didn't know I had to add the jndi properties to the connection.xml maybe you can update the documentation.

Compiler can't find other classes

I've got this bad problem that's been bugging me all weekend, and I can't work out how to fix it. A few months ago I was able to write classes that use other classes I've defined no problem. I just started using my compiler again, and now when I want to use different classes I've written, the compiler says that it can't find the other class:
D:\uni\2005 Sem2\cse12ipj\assignment\HabitatModule.java:12: cannot find symbol
symbol: class Module
public class HabitatModule extends Module
^
1 error
Tool completed with exit code 1
I've compiled the Module class and it doesn't have any errors. I'm guessing that there's something wrong with the classpath variable. Is that right? I'm using java 5.0.

This is the base class. It compiles fine.
public abstract class Module
private char type;
private String axisCode;
private Module moduleList;
abstract int getSpareCapacity();
When I compile this next class, the compiler on my PC says that the class Module can't be found:
D:\uni\2005 Sem2\cse12ipj\assignment\Habitat.java:12: cannot find symbol
symbol: class Module
public class Habitat extends Module
^
1 error
Tool completed with exit code 1
public class Habitat extends Module
private class Person
private String name;
private int id;
private String speciality;
private int maxPeople;
private int nrPeople;
private char subType;
private Person personList;
private String purpose;
public Habitat(int maxPeople, char subType, String purpose)
this.maxPeople = maxPeople;
nrPeople = 0;
this.subType = subType;
this.purpose = purpose;
public int getSpareCapacity()
return maxPeople - nrPeople;
If I compile it on any other machine, it's fine. I was looking on the web, and the CLASSPATH doesn't have to be changed for classes in the same directory.
