The only thing that I see that looks funny to me is when you pass the request object into the method using <%=request%>, Im not sure whats going to happen here because that is suppose to print the results. Have you tried simply using <%request%>?

Date loading - Member containing comma in Point-of-View

Hi,
I tried loading date into essbase via planning. My point-of-View contains a member which has comma in it.
When loading it is considering that member as two different members.
Has anyone tried loading data into planning with members having comma.
Eg. Item No.,Start Date,Point-of-View,Data load Cube Name
30103,11-02-2011,"Actual,Version1,Dazzing Infotech, Inc,230"Capex
I have 6 dimensions say.
Dazzing Infotech, Inc is a member in dimension. It has comma which is seperating it as two members.
Error when loading is "Dazzing Infotech" doesn't exist or you do not have access to it.
Has anyone worked on this issue previously.
Thanks

Cross post :- Data loading - Member containing comma taken in point-of-view
Cheers

The deployment problem in JSP using JavaBean

Hi there,
I followed the descriptions in Writing Enterprise Applications with
Java 2 SDK, Enterprise Edition tutorial to build a set of programs to run JSP with JavaBean, and I also followed the steps in creating new WAR file, but some how it wouldn't work after I deployed them. I run the JSP in IE and got a message like this:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 20 in the jsp file: /1bonus.jsp
Generated servlet error:
c:\j2sdkee1.3.1\repository\orbit\web\JSPRoot\$1bonus$jsp.java:63: Class org.apache.jsp.JBonusBean not found.
JBonusBean jbonus = null;
^
I used the deploytool to create the WAR file, and after I added the 1bonus.jsp, I also added JBonusBean into the WAR file. I found 1bonus.jsp was added into the WAR file, but there's no JBonusBean appeared under the WAR file.
Could you please tell me is there anything wrong?
Thanks for your time.
Regards,
Eric

I think you have not imported 'BonusBean' in your jsp. Code this line in your jsp at the top.
<%@page import="BonusBean" %>

Jsp and JavaBean problem

Hi All,
I need UR help
Problem:
I have a javaBean and a jsp page say test.class and test.jsp respectively.
Now the problem is when i run my jsp in web browser with path
http://localhost:8080/mypackage/test.jsp and use test.class in it. It give me an error Class test.class Not Found but when i give the path http://localhost:8080/examples/jsp/parentpackage/mypackage/test.jsp
it works fine.
I am using Tomcat 3.2 and i have already made changes in server.xml for my jsp files thats why i can run my programs with the earlier path but dont know why its giving the error when i use javabean,
Also i have put my javabean class in---parentpackage/mypackage/test.class
Thanks
Amit

Two JSPs using JavaBeans

Hi,
I have a JSPs and JavaBeans question.
There are two JSP files. One.jsp and Two.jsp.
One.jsp include code that use the JavaBeans from Two.jsp:
<%
     if (bl.getDmlOperation() == NcepConstants.UPDATE) {
Two.jsp have:
<jsp:useBean      id="bl"     class="TestsPrivateBean" scope="session"/>
<%@ include file="One.jsp" %>
When I run this code in TOMCAT, it can run in runtime with no problem.
But the company it now moving to use an IDE (Oracle JDeveloper 9i) with require me to build this into one project. When I try to build the project, it shows error in One.jsp as "variable bl not found in class_One".
When I put the <jsp:useBean      id="bl"     class="TestsPrivateBean" scope="session"/> code into Two.jsp, it shows "duplicate found error".
How should I do to fix this?
Thanks
Kenny

It sounds like it's compiling One.jsp independant of Two.jsp, which will cause the first error. Try renaming One.jsp to One.inc or something. That way it doesn't try compiling One.jsp at all (it won't be there).

JScrollPane containing JPanel HELP!

Hi again,
I'll try my luck again!
Ok, I have a JPanel that uses a GridBagLayout with 3 columns and many rows. Each row is of the form:
[JLabel][JTextField][JButton]
Ok. Since I have many of these rows, and my application should be a constant size, I need to somehow make you able to scroll down the list of these labels,textfields and buttons - to the one you want. I have tried making the containing JPanel the viewport of a JScrollPane, however, when I only have a couple of rows of labels, textfields, and buttons, each expands to fit the viewport size - and they turn out looking really dumb.
How can I get it so that the labels, textfields and buttons are only the height of the text in each?
Please please, please, please help me.
sincerely, Edd.

Chenge the weight (x&y) in the GridBagConstraints of the components you don't want to expand to 0.0. Change the fill to GridBagConstraints.NONE.

I have my data.jsp page in WebContent/WEB-INF/ folder. When I just run date.jsp in a browser as: http://localhost:8080/Date/date.jsp, it gets launched into the browser correctly. But when I add a JavaBean "TimeFormatterBean.java" in the Java Resources:src folder and use it in date.jsp page, I get errors as under:-

If anyone could please help me out with this, it would be very helpful
Thanks a lot!

You probably should place TimeFormatterBean inside a package, or maybe you could try importing it , even if it�s in the default package, with something like this <%@ page import="TimeFormatterBean" %> at the top

Are there any Examples of Servlet or JSP load balancers?

Any CASE tools for Java, JSP, and JavaBeans?

For Java, JSP, and JavaBeans can we find something that can help us automate certain tasks?
For example, CASE tools is an acronym for Computer Aided Software Engineering tools. I have a colleague use software to generate robust code for the database layer and with a few clicks of a button after the database is designed he can generate code that would otherwise take an hour or even hours to write and debug and test.
Thanks for your time and help in advance!

The ones I know are MVCase (from Brazil) and Jude (from Japan). Both are free and I haven't fully tested them yet. It may help you.

Could not load execution container: null

Hi,
I am trying to create GPs programatically. The Callable Object type is "Web Pages"
I am able to create a CO of the above type by using:
IGPCallableObjectType wpCoType = coTypeManager.getCallableObjectType("com.sap.gp.url");
I am setting the URL in this fashion:
    pco.setConfigProperty("URL", "www.myUrl.com");
Also I am adding one Input parameteras String in this fashion:
IGPStructureInfo input = callbleObj.getInputParameters();
     IGPAttributeInfo attr = null;
     attr = input.addAttribute("paramName", IGPAttributeInfo.BASE_STRING);
     callbleObj.setInputParameters(input);
When I try to test the CO, it throws this error:
Could not load execution container: null
Ant insight on this?
Thanks,
Apurv.

I have created a CO of type Web Page (com.sap.gp.url) programatically. I am not quite sure what you mean by runtime dependency.
     IGPCallableObjectTypeManager coTypeManager = GPCallableObjectTypeFactory.getCallableObjectTypeManager();
     IGPCallableObjectType wpCoType = coTypeManager.getCallableObjectType("com.sap.gp.url");
     IGPCallableObject callbleObj = gpDesigntimeUpdateManager.createCallableObject(wpCoType , locale, "CO: "actionCO.name, "CO: "actionCO.name +" Description", folder.ID)
     IGPPhysicalCallableObject pco = callbleObj.resovlePhysicalCallableObject();
    // set two result states: complete
    pco.addResultState("COMPLETE", "complete");
    // define an exception
    pco.addProcessException("EXCEPTION", "exception");
    // set configuration property
    pco.setConfigProperty("URL", "http://www.myurl.com");
    pco.setInputViewVisible(true, IGPPhysicalCallableObject.VIEW_VISIBILITY_PURPOSE_ALL);
     //      obtain copy of the input parameter structure of our object
     IGPStructureInfo input = callbleObj.getInputParameters();
     IGPAttributeInfo attr = null;
     attr = input.addAttribute("grails", IGPAttributeInfo.BASE_STRING);
     callbleObj.setInputParameters(input);
     gpDesigntimeUpdateManager.save(callbleObj)
     gpDesigntimeUpdateManager.release(callbleObj);
     gpDesigntimeUpdateManager.activate(callbleObj)

How to improve jsp load time?

Hi everyone --
Got a question for all of you.
I have a form in a JSP, which does a (Oracle 9i) db lookup on 13 fields and populates the drop-down boxes. The load time for the JSP is slooooww.
These are my options for speeding up the load time (I think):
1. When the web/app server starts the application, have it do all the db lookups and store the resultsets...somewhere. Maybe have some dblistener thread that periodically checks for updates to the db. Then, when someone actually requests the JSP, all the JSP has to do is read the pre-populated drop-down boxes and load.
2. Wait until someone requests the JSP and store all the resultsets as cookies for the session. The resultsets will be good for the home JSP and its sister. This doesn't really solve the problem, since the initial load will still be slow.
3. Combine all the lookup statements into one huge statement, and store the results somewhere. This method queries the db only once, and the drop-down boxes can be populated from one query (instead of 13 separate connections and queries).
All of these ideas seem mediocre to me, and they don't address the fact that the results of the queries change contantly. What I need is a
way to make the JSP load quickly and with the most current information.
Does anyone have any ideas? Which of my suggestions is rather boneheaded?
Thanks for any advice,
-Kwj

It's still not perfect, but it's better at least.
I'm querying 4 different tables overall, and I have a Db class that the jsp instantiates.
from home.jsp:
Db d = new Db();
ResultSet [] all = d.getAll();
<body>
%>
<tr><td align=right>Correspondence ID: </td><td><select>
<option label=""></option>
<%
    rs = all [1];
    while(rs.next()){
%>
        <option><%=rs.getString("sak_correspondence")%></option>
<%
%>
</select></td>
</body>
[\code]
from Db.java:public ResultSet [] getAll() throws SQLException
ResultSet [] all = new ResultSet [4];
all [0] = con.prepareStatement
("select nam_category from doco.corr_category " +
"order by nam_category asc").executeQuery();
all [1] = con.prepareStatement
("select sak_correspondence, dte_received, dte_response_due, " +
"dte_sent, file_path, id_outref, subject " +
"from doco.correspondence").executeQuery();
all [2] = con.prepareStatement
("select nam from doco.corr_type order by nam asc").executeQuery();
all [3] = con.prepareStatement
("select nam_subcategory from doco.corr_subcategory " +
"order by nam_subcategory asc").executeQuery();
return all;
}//getAll()

JSP, JavaBeans and iPlanet 4.1- Unable to load JavaBean

I get the following error when trying to access a JavaBean from a JSP page. I have tried just about everything including using the <@page import /> in the JSP page.
I can get it to run perfectly in Tomcat 3.2 but it must run in iPlanet 4.1. I think the solution should be fairly simple I just can't find it.
Any help would be greatly appreciated.
Thanks.
The exception is as follows (thrown on running the generatePage.jsp linked from index.jsp).

To solve this problem you have to:
include <@page import /> tags importing the JavaBean to be used.
In the classpath of iPlanet include the directory in which your JavaBeans are placed.
Also in the classpath of iPlanet include the root directory of you web site containing the JSP's. this should then solve the problem.

How can I load javaBeans in jsp without restart WL?

hi,
          Restart WL every time I modify my bean really drive me crazy!
          Following the manual, I set up my servletclasspath and put all the beans
          I use in my jsp under that directory, I find out something strange:
          if my beans' scope is page and if I modify the jsp page as well every
          time I modify the beans, I can autoload the fresh new beans without
          restarting;
          if my beans' scope is larger than page( such as session), then even I
          modify the jsp, instead of the fresh new beans I get the following
          exception:
          java.lang.ClassCastException: com.aa.mybean at

          who knows how to autoload the new session scope javabeans in a jsp page
          without restarting WL?
          thanks in advance...


That makes sense. If the session contains an instance of an old class, and
          you cast it to the new class, then you should get a class cast exception.
          One way around this is to use interfaces that are (for development) in one
          of the outer class paths (system or weblogic, I can't remember which) ...
          the only time you mention the class name is to new it. Then you cast the
          contents of the session attributes to those interfaces. The interfaces can
          not change without restarting the server, but the implementations can.
