Where to set the classpath for custom classes in jsp

Hi,
we have created our custom classes in and ported in contentDB and that classes are internally using some jar files. Previously we have set the classpath of all the jar files provided in CDB devkit in the orion-web.xml but if are opening the explorer.jsp or any other jspx of contentDB we are getting the classcastexception and page is not opening.
Is there any problem in setting the classpath. Please if any one knows abt this, reply as soon as possible.
thanks,
swapna soni.

I think it is Oracle 10g Release 2... since when I click the top OAS link in the Enterprise Manager Console, it took me to 'Enterprise Manager 10g Grid Control Release 2' this page.
And...10g Application Server Control Release 10.1.2.0.1, I think 2.0.1 means Release 2.
Thanks and let me know if you need something else.

Setting the CLASSPATH for the derby.jdbc embedded class

I am new to Java and am trying to connect a simple (hello world simple) terminal app to a javadb embedded database - I am using the classFor to load the jdbc - but when I run my app I get an error saying the class can't be found. I think I just need to add the jdbc to my classpath. I've tried using
export CLASSPATH=...
but I still get the same error.

Thank you SO much for your response! I have tried the following (this is where I found the derby.jar):
javac -cp /usr/lib/jvm/java-6-sun-1.6.0.07/db/lib/derby.jar test.java
But I am still getting the same error:
java.lang.ClassNotFoundException: org.apache.derby.jdbc.EmbeddedDriver
Here is my code - so far it doesn't really do anything, I just want to get it connected, then I'll start adding some simple db code and go from there:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.Statement;
class HelloDave
    public static void main(String[] args)
        try
            Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
        catch (Exception e)
            e.printStackTrace();
        System.out.println("Hello, Dave");
}

How to set a classpath for referring classes

I am using windows vista.....I had assigned classpath for Variable name and given address of class in variable type ..even then compiler does not recognize class path..........

Thanks but it is not what I am really asking or I may didnt understand..
The program is working ok through JCreator.. My problem is when I create an Installation file and then run it..
the program is being created just fine but when it has to load the jdic then it blocks...
This is something that must be done through variables right?
If you ever used Install4J there are 2 columns where you declare variables..
The first column is for Variable name and the second one is Variable Value..
Sorry for buthering you with all this but this is the first time that I am dealing with jar files!
Thanks again !

Hi Timo,
My jdev version is 10.1.3.3.0, this is for R12. By PR i mean to say process request and PFR process form request in the controller.
In the Process request of the controller, i am finding the checkbox bean and assigning the firepartialaction for it.
Later in the process form request for the fired event, i am trying to handle the rendered property of the messagetextinput. Is this a right approach?
my code below
public void processRequest(OAPageContext oapagecontext, OAWebBean oawebbean)
super.processRequest(oapagecontext, oawebbean);
OAApplicationModule oaapplicationmodule = oapagecontext.getApplicationModule(oawebbean);
OAMessageCheckBoxBean oamessagecheckboxbean = (OAMessageCheckBoxBean)oawebbean.findChildRecursive("X_FLAG");
if(oamessagecheckboxbean != null)
oapagecontext.writeDiagnostics(this, "Message check box Bean found:", 1);
FirePartialAction firepartialaction = new FirePartialAction("change");
oamessagecheckboxbean.setAttributeValue(PRIMARY_CLIENT_ACTION_ATTR, firepartialaction);
oamessagecheckboxbean.setFireActionForSubmit("change", null, null, true);
oapagecontext.writeDiagnostics(this, "setting fire event", 1);
public void processFormRequest(OAPageContext oapagecontext, OAWebBean oawebbean)
super.processFormRequest(oapagecontext, oawebbean);
oapagecontext.writeDiagnostics(this, "Inside Process Form Request", 1);
if("change".equals(oapagecontext.getParameter(OAWebBeanConstants.EVENT_PARAM)))
OAMessageTextInputBean bean = (OAMessageTextInputBean)oawebbean.findChildRecursive("X_NUMBER");
if(bean!=null){
bean.setRendered(Boolean.TRUE);}

Can anybody tell me how to solve the problem. Thanks a lot.

You will have to create the servlet mapping in the Web.xml file
<servlet>
             <servlet-name>FirstServlet</servlet-name>
             <servlet-class>FirstServlet</servlet-class>
    </servlet>
<servlet-mapping>
        <servlet-name>FirstServlet</servlet-name>
        <url-pattern>/servlet/FirstServlet</url-pattern>
    </servlet-mapping>

How do I set the classpath for IWS?

I'm using iPlanet Web Server 6.0 and I have a JSP that imports a class, ClassX. I place classX in the ClasseCache directory, which works. But when ClassX imports javax.jms.* (found in a jar file) there is a run time error because j2ee.jar doesn't seem to be found by IWS. How do I get IWS to look in j2ee.jar for these jms classes?

It is never advisable to store large data sets in the session. But it will depend on a lot of factors:
1. How costly is the query retrieving the data from the database?
If it's a complex query with lots of joins and stuff, then it will be better to store it in the session as processing the query each time will take a lot of time and will decrease performance. On the other hand if the query is simple then it's advisable not to store it in the session, and fetch it each time.
2. Are there chances for the data to become stale within a session?
In this case storing the data is session will mean holding the stale data till the user session lasts which is not right.
3. How many data sets does the session already holds?
If there are large no. of data sets already present in the session, then it's strictly not advisable to store the data in the session.
4. Does the server employ some kind of caching mechanism?
Using session cache can definitely improve performance.
You will have to figure out, what is the best way analyzing all the factors and which would be best in the situation. As per my knowledge, session is the only place where session specific data can be stored.
Also, another thing, if the data set retrieved is some kind of data to be displayed in reports, then it would be better to use a pagination query, which will retrieve only the specific no. of rows at a time. A navigation provided in the UI will retrieve the next/previous data set to display.

Does weblogic.Deployer set the CLASSPATH?

Hi,
I need to deploy an application with the weblogicDeployer utility. Does it automatically
set the CLASSPATH, as is done with the Admin console? Or do I need to set the
CLASSPATH explicitly?
Thanks,
-Ami

ah. weblogic.Deployer and the console use the same underlying API to
our Deployment subsystem. There shouldn't be any difference in
application behavior (eg classpath).

Setting the Classpath of a VM launched using JDI

I using VirtualMachineManager to get a LauchingConnector and fire off a new VM.
It seems that there should be some way of me setting the classpath for this new VM.
In general I'd like a list of the options that I can put in that argument map.

In J2SE 5.0, jdb has a new option that will list the available connectors and the arguments that can be passed to them EG:
jdb -listconnectors
Available connectors are:
Connector: com.sun.jdi.CommandLineLaunch Transport: dt_socket
description: Launches target using Sun Java VM command line and attaches to it
Argument: home Default value: /net/foo/p/jdk/1.5.0/jre
description: Home directory of the SDK or runtime environment used to launch the application
Argument: options (no default)
description: Launched VM options
Required Argument: main (no default)
description: Main class and arguments, or if -jar is an option, the main jar file and arguments
Argument: suspend Default value: true
description: All threads will be suspended before execution of main
Required Argument: quote Default value: "
description: Character used to combine space-delimited text into a single command line argument
Required Argument: vmexec Default value: java
description: Name of the Java VM launcher
This means that you would want to put "-classpath ......" into the 'options' argument.
Hope this helps

How to set the Classpath of the Manifest to use jars which are included?

Hi,
I want to set the classpath for jars which are included in another jar, wihich I want to execute. At the moment I unzip them and include them afterwards, but there should be a more handy way to do this.
Please post an example of a Classpath declaration for the Manifest, assuming the jars are at the top level of the archive.
If it shouldn't be possible do that, please explain me why.
Perhaps it might be diffuclt for java to decide if a classpath location starts with the current-dir or the current-jar, but I assume that there is a special syntax to sort out such probems.
Thanks a lot in advance.
Greetings Michael

Java's classloader doe not support jars within jars. There are some 3rd part solutions, one is "one jar" at sourceforge. Search for others.

TabStripLayout-View: Where to set the text?

Hello,
I am using a view of the kind TabStrip. For your understanding> Not a normal view with a tabstrip. It is a view similar to Gridlayout, just TabStripLayout.
I can not find where to set the text for the individual tabs, e.g. TAB1, TAB2 etc.
Does anzbodz know?
Regards Thank Mario

I assume you are using a TabStrip layout of a viewset. The tab 'captions' are set in the properties for the viewset. In the explorer outline, expand Windows and click on the ViewSet and in the properties for the ViewSet it will have the captions listed for the tabs and you can change the text there.
Be aware that the tab strip layout for viewsets is a bit limited. As far as I can tell the navigation plugs between views do not work. There are other forum questions/answers on how to use a normal TabStrip element rather than a viewset to get around this.

Setting the CLASSPATH from the JVM by a class

Hy experts
I have an application thats searching a jar file and have to access classes from this jar file.
There are two ways to do this:
1.
Loading the jar file byte by byte and create the classes to load them into memory. This is the hard way.
2.
Setting the CLASSPATH variable in the running program! Thats the easy way! May how does it works?
Is there any possiblity to set the classpath in a running application or only in the shell?
Thanks for help
konrad

the classpath is readin when you run the JVM ie issue the 'java' command, the environment cant be altered to update a new classpath. However, why not just put the files you wish to load at runtime within the current classpath you've setup. If you use the System.loadLibrary(), you should be able to pick up the classes you wish to readin at run time via this approach.
good luck
