Forte with JSP?

hi all
i'm using FORTE 4.0 to work with java, and i'd like to use it also with JSP, but i have a little problem... jsp page's graphical design....
so i thought it's impossible to use it as a stand alone jsp editor, don't you?
please, send me your opinion
thanx
sandro

You can try to create a HTML layout using any GUI editor, like dreamweaver, frontpage, etc. Then paste the html code on Forte's source editor. Insert/modify codes where necessary. It helps a lot for those with little knowledge of HTML. Hope that helps.

SQL query with JSP and WML-parameters

Hey,
Could you help me?
I'm trying to do the following. WML deck card 1 send parameter to same WML deck's card help. I try to read the parameter with JSP in card help by putting the parameter to SQL query, but it doesn't work. I can read the parameter with WML in card help. I can also print the value of the parameter with JSP if I generate WML with JSP.
/*parameter sending from card 1 to card help*/
out.println("<go href='#helpcard'>");
out.println("<setvar name='valittukurssi' value='$(valittukurssi)'/>");
/*parameter read with WML in card help */
<p>Valitse kurssi.
$valittukurssi</p>
/'parameter read with JSP by generating WML with JSP*/
out.println("<p>$valittukurssi</p>");
/* SQL query with JSP */
ResultSet uudettulokset = uusilause.executeQuery("select * from kurssi where lyhenne='$valittukurssi'");
Thanks,
Rampe

You're problem is easy to fix. You're confusing WML variables with JSP variables. See below:
>
/*parameter sending from card 1 to card help*/
out.println("<go href='#helpcard'>");
out.println("<setvar name='valittukurssi'
value='$(valittukurssi)'/>");
Above you set a var that will work on the phone, not in JSP.
/*parameter read with WML in card help */
<p>Valitse kurssi.
$valittukurssi</p>
Yes the above does display the parameter, because it is a client side WML var, but you cannot use this variable in the JSP code (that's why your SWL fails).
/'parameter read with JSP by generating WML with
JSP*/
out.println("<p>$valittukurssi</p>");Here's you're problem, the above line is EXACTLY the same as the one before it. When the container parses through this JSP code it translates the above line to:
<p>$valittukurssi</p> on the WML page and the CLIENT uses it's local variable to display it.
What you need and want is to have a variable that can be used in JSP code and output to your WML page. Here's how it's done:
out.println("<go href='#helpcard'>");
String some_name = "valittukurssi";
out.println("<setvar name='"+some_name+"'
value='$("+some_name+")'/>");
//note that you may have to escape the ( and ) with a \
//so we displayed the variable above into the WML page, now we can use it in the SQL query:
/* SQL query with JSP */
ResultSet uudettulokset =
uusilause.executeQuery("select * from kurssi where
lyhenne='"+some_name+"'");//the end of the command is: " ' " ) ;

Create a new directory in server with JSP

Hi,
How can I create a directory in server with JSP.
File dir = new File("a");
dir.mkdir();
does not work. what do I do?
best regards,

Hi
Check the following things.
1. What is the path where you are creating the directory.
2. Do you permissions to create file in that directory.
3. do a delete on that filename if that exists just to be sure. isdeleted = filedir.delete(). Check the boolean flag isdeleted too.
Thanx and Regards

Running other server-side applications with JSP

Hi,
I'd like to know, if is possible run with JSP (Servlet, or JavaBean) other application, which support COM. I used something like this in JavaScript:
application=new ActiveXObject("excel.application");
and I had all possibilities of its API. I'd like to use excel as data source for user-friendly data input.
Thanks for all suggestions

Hi,
I don't realy understand your question.
If your javascript work using activeX, this code is executed on the client side (like the excel application and the excel file).
You can, with a JSP, generate the html page that contain the script.
Where is the problem ?

How can I create a Login-page with jsp???

Hello,
I have to create a page with JSP code on the Netweaver Developer Studio.
But I do not know how I do it.
Can anyone tell me what to write in the portalapp.xml?
An example would be very helpful.
Thank you
Greetings

As you can see in the example:
The portalapp.xml file (deployment descriptor) provides configuration information for your application, and defines the components and services in your application. For each component and service, you specify the implementing Java class and configuration information.
For more information on the format of the portalapp.xml, see Deployment Descriptor (portalapp.xml).
<application>
    <application-config>
        <property name="SharingReference" value="com.sap.portal.navigation.service, com.sap.portal.navigation.api_mimeservice, com.sap.portal.navigation.helperservice"/>
        <property name="Vendor" value="MY_COMPANY"/>
        <property name="SecurityArea" value="PERMISSION"/>
    </application-config>
    <components>
        <component name="SimpleNavigationExample">
            <component-config>
                <property name="ClassName" value="MY_CLASS"/>
                <property name="SecurityZone" value="no_safety"/>
            </component-config>
            <component-profile/>
        </component>
    </components>
    <services/>
</application>
You can only update in this example, your class name and other details:
<property name="Vendor" value="sap.com"/>
<property name="SecurityArea" value="MyCompany"/>
<property name="ClassName" value="LOGINCLASS"/>
<property name="SecurityZone" value="no_safety"/>
Modify this portalapp.xml file as follows:
       1.      NAVIGATION SERVICE, so you must add references to the following portal applications that define these services:
        com.sap.portal.navigation.service
        com.sap.portal.navigation.api_mimeservice
        com.sap.portal.navigation.helperservice
       2.      In the <application-config> section, create the following properties that help to define the security zone for all components and services in this application:
○     Vendor: String identifying the company or organization that provided the application, for example, sap.com.
○     SecurityArea: String identifying the security area for the application, for example, NetWeaver.portal.
       3.      In the <component-config> section for the mySiteMap component, create the property SecurityZone to define the specific security zone for the component.
For Permission, check this document:

Help me!! How to use JavaScript with JSP ??

I am using JDeveloper and I created a screen in JSP which uses a bean for database connectivity and retriving info onto the page.
The page has a ListBox where list items are populated from the database.My requirement is

I tried to use 'JavaScript' for triggering the event with 'onChange' event of the ListBox.But the event is not getting invoked. I think JavaScript is not working with JSP.
Please help me with how to Use javaScript with JSP or any other alternative where I can meet my requirement.

I have also gone through the 'readme' but I don't know how to extract .jar file.

When someone selects say the State of Pennsylvania. then we have an On change event that runs a Javascript to go get all the cities in Pennsylvania.
Proble we are having is that inorder for the Javascript to work , we currently have to send all the valid data.
Do you know of any way to dynamically query the the Oracle database in Javascript

Excel with JSP

Thanks a lot...

There is a example in Marty Hal;l's book"Core Servlets and JSP pages".

Use of Threads with JSP's

Can you use threads in a web application that uses JSP's plus Servlets and Beans ?
We have a JRUN 3.1 application using JSPs, Servlets and Beans. Shortly after we went live it became apparent that any 2 users using the same object experienced problems as one object was overwriting another. In a panic the problem was solved by whacking SYNCHRONISED on all objects.
Now we want to write another application, are there strategies for using Threads with JSPs?
Would this be part of the webserver configuration or would the application be coded in a certain way ?
Please can you give me a simplistic answer or point me to some documentation that gives a simple overview.
Thanks Steve

INSERT statement with JSP

          I can do the insert if I code the values of the variables in the statement,
          but when I try to use variables to do the insert it tries to insert the
          variable name and not the value of the variable into the table.
          Thanks,

Why JavaBeans with JSP

Hi,
I know its an easy question and probably a silly one to ask, but still please take time to answer this. Why do we use JavaBeans with JSP to make use of reusable code. Cant we use simple classes for this?
Thanks in advance

Hi,
JavaBeans technology is the component architecture for the Java 2 Platform, Standard Edition (J2SE). Components (JavaBeans) are reusable software programs that you can develop and assemble easily to create sophisticated applications. By using Java beans, JSP allows you to keep much more of your code separate from the html than other html embedded languages. Java beans basically let you keep all the logic of your page (like the code to connect to a database, manipulate data etc�) in a separate file known as a Java bean. Then from within your html page - all you do is use one tag to 'use' the bean, and then a few other short tags to send data to and from the bean.
the website http://java.sun.com/products/jsp/html/jsptut.html is a good start, simple and easy understand.
Good luck!

SQL problem with JSP

In sql statements with JSP. Heres the deal:
Access database:
Tablename: EVENT
FieldName: event_id
DataType: Number
I want to compare the event_id to an integer variable called "var" in a WHERE clause in an SQL statement through a JSP.
String query = "SELECT * FROM EVENT WHERE EVENT.event_id = 'var' ";
It says "Data type mismatch in criteria expression."
Any Suggestions? I thought this should be straight forward! am i missing something?

if i am reading correctly "var" is an int variable correct? If this is the case then the following will work;
String query = "SELECT * FROM EVENT WHERE EVENT.event_id = " + Interger.toString(var) ;
Hope that helps ( and i hope i read your problem correctly)
