JSP and Service on EP 6.0 SP7

Hi,
I can't import my service into my JSP, I have the following error :
Error in executing a process for compilation, F:/usr/sap/NW4/JC00/j2ee/cluster/server0/apps/sap.com/irj/servlet_jsp/irj/root/web-inf/portal/portalapps/appli2menu/work/pagelet/_sapportalsjsp_appli2.java:17: '.' expected import ServiceJW; ^ 1 error .
Exception id: 04:52_28/10/04_0033_3928950
I have modified the jsp.addclasspath in the file workplace.proporties (this variable was empty before i assign it) but I have always the same error...
Somebody could help me ?
Best regards,
Denis

Hi, seems like there's some typo in your jsp. Check the .java file listed with a java editor (like eclipse or devstudio.). Maybe you'll find the typo this way faster.
Most often, a multiline page import hampers jsp compilation,
e.g.
<%@page import="java.util.List,
java.util.Map"%>
needs to be
<%@page import="java.util.List,java.util.Map"%>

Tomcat JSP HTTP Services, BlazeDS and AMF Help Understanding This in Cairngorm

Hi
I have an existing Tomcat application using JSPs and a Flex Client that uses HTTPService (Cairngorm). Can we use BlazeDS to access these JSPs over AMF? How might that work in Cairngorm.
Thanks

There may be other ways to do this but here's what I would do:
1) add a results method to the remote object:
src.result="onResult(event.result)";
2) add the callback method: private function onResult(event : * = null)
:void{
if(event is
ArrayCollection)
myData =
ArrayCollection(event);
3) add the variable: private var myData:ArrayCollection;
4) make the dataProvider for the grid use the my data :
dataProvider=""
You can probably avoid all this by adjusting your dataProvider. I am just
not sure what it would be without experimenting. But definitely not what
you have. Maybe just {svc.result}.

Domain Object and Service oriented pattern

We have J2EE based application with following components, we are facing some issues with existing system.
Current System : We have J2EE based application. The following is the flow.
Client Layer [including JSP, Struts ] action classes  Delegates  Session fa�ade [Session bean]  DAO EJBDAO  EJB. We use CMP, xDoclets , JBOSS.
1.     Our Domain objects are heavy. I know they are suppose to be coarse objects but they take more time in loading. Also, we noticed one thing that lot of methods are called during Domain Object creation process and it takes lot of time in loading. Actually, we dont really know what is happening as we are using CMPs.
Question :
-     Any input on what can be done to avoid Domain object excessive loading time.
-     Anyone can share there experiences with Domain objects. Are you facing issues related with performance.
-     We dont use DTO, we pass domain objects between. Do you see any problem in doing that.
2.     Currently, our system was used by one single front end or lets say we have only one client but soon we will have more clients using it.
Question :
-     What should be our design approach. How can we make our system more like service oriented. If the two clients demand different business logic then how it will be handled. Business logic common to all the clients will be handled by which layer and business logic specific to client will be handles by which layer.
-     Please suggest based on our existing infrastructure. We don�t want to use SOAP or cannot make drastic changes to our flow.
We have domain and services in the same package and we are doing the refactoring of code, your inputs will be valuable.
Thanks

What type of logger do you use and what is the loger-level during production?
If it is log4j set the logger to level INFO or WARN.
This might sound trivia but can make a difference between 20seconds and 500 ms.

Communication between jsp and abstractportalcomponent

Hello All
Communication between jsp and abstractPortalComponent.
jsp contains one input text field and one submit button.
when the user clicks on submit button it will call the component and that input value will
display in same jsp page.
how this communication will happen?
Rgrds
Sri

Hi Srikanth,
In the JAVA File,
OnSubmit Event,
String inputvalue ;
InputField myInputField = (InputField) getComponentByName("Input_Field_ID");
if (myInputField != null) {
               inputvalue = myInputField.getValueAsDataType().toString();
request.putValue("textvalue", inputvalue);
request is IPORTALCOMPONENTREQUEST Object.
In JSP File,   to retreive the value,
<%
String textstring = (String) ComponentRequest.getValue("textvalue");
%>
In PORTALAPP.XML File,
<component name="component name">
      <component-config>
        <property name="ClassName" value="classname"/>
        <property name="SafetyLevel" value="no_safety"/>
      </component-config>
      <component-profile>
        <property name="tagLib" value="/SERVICE/htmlb/taglib/htmlb.tld"/>
      </component-profile>
    </component>
Using the code above, You can pass and read values between abstract portal component and Jsp Page.
Instead of this, I suggest you to use JSPDYNPAGE Component for Data Exchange.
Check the [Link|http://help.sap.com/saphelp_nw2004s/helpdata/de/ce/e0a341354ca309e10000000a155106/frameset.htm].

Deploying a WAR file containing .jsp and servlets (also uses JNI)

Deploying a WAR file containing .jsp and servlets (also uses JNI) on Windows 2000
We had problems making it initially work on Sun ONE Web Server 6.0 Service Pack 1 because of lack of good iPlanet Web
Server documentation on deploying such files.
This is how we went about it:
1) Make one of the servlet and JSP (must call another Java Class) web application (.war) examples work with iPlanet Web
Server.
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\HelloWorld\HelloWorld.war
and
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
a) Go to your Web Server Administration to deploy the application using GUI Web Application Deploy.
(We usually use command line, we experienced some issues with the GUI version, but maybe it is fixed in the new Web Server
service packs)
From browser, open http://yourserver:8888/
Click on Select a Server:Manage
Click on Virtual Server Class
Click on https-yourserver
Click on the Web Applications Tab
Then, click on Deploy Web Application
Enter the following -
WAR File On: Local
WAR File Path: C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
Application URI: /jakarta
Installation Directory: c:\iPlanet\examples\jakarta-examples
By clicking on OK it deployed the application.
I can verify that it is deployed by selecting "Edit Web Applications" and I see the following entry:
Edit     /jakarta     c:/iPlanet/examples/jakarta-examples
Also, c:/iPlanet/examples/jakarta-examples should have the similar following directory structure ..
- [images]
- [jsp]
- index.html
- [servlets]
- [META-INF]
- [WEB-INF]
- [classes]
- [tlds]
- web.xml
- index.html
I restarted the server and accessed it using the following URL from my IE browser:
http://yourserver/jakarta/index.html
Then I clicked on the JSP Examples and tried some JSP examples.
b) Alternatively, you can also deploy the same example from the command-line.
Make sure C:\iPlanet\Servers\bin\https\httpadmin\bin\ is in your path
wdeploy deploy      -u /jakarta
          -i yourserver
          -v https-yourserver
          -d c:\iplanet\examples\jakarta-examples
          C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
Restart the web server (I don't think you have to restart, but .. might as well).
2)Deploy your web-application
My Foo.war has the following structure.
You can use jar tf Foo.war to look at the file contents from command line (assuming you have JDK installed and the bin is
in your PATH)
Foo.war
- [META-INF]
- [WEB-INF]
- web.xml
- [classes]
- Bar.class
- MoServlet.class
- [lib]
- ThirdParty.jar
- [natlib]
- extlib.dll
- foo.jsp
Here is our application scenario:
foo.jsp uses a class call Bar (it is not in any package). The Bar java class uses classes from ThirdParty.jar. The
ThirdParty.jar in turn uses JNI to load library extlib.dll. foo.jsp also calls /servlet/Mo as well.
Now to deploy it, do the following:
(a) Make sure that within foo.jsp, you import the Bar class ( I don't know why you have to do it, but if you don't you get
JSP compile error).
<%@page language="java" import="Bar" contentType="text/html"%>
(b) Check web.xml (for Servlets)
Within web.xml, make sure you have the following mappings:
<servlet>
<servlet-name> MoLink </servlet-name>
<servlet-class> MoServlet </servlet-class>
</servlet>
<servlet-mapping>
<servlet-name> MoLink </servlet-name>
<url-pattern> /servlet/Mo </url-pattern>
</servlet-mapping>
(c) Deploy the application
Using command line:
wdeploy deploy      -u /foo
          -i yourserver
          -v https-yourserver
          -d c:\iplanet\examples\foo-dir
          Foo.war
(d) Change web-apps.xml file (for picking up ThirdParty.jar)
It is located in
C:\iPlanet\Servers\https-yourserver\config
You should see something similar to following after successful deployment.
<web-app uri="/foo" dir="C:\iPlanet\examples\foo-dir" enable="true"/>
Change it to look like following to pick up the ThirdParty.jar
<web-app uri="/foo" dir="C:\iPlanet\examples\foo-dir" enable="true">
<class-loader reload-interval="300"
          classpath="C:/iPlanet/examples/foo-dir/WEB-INF/lib/ThirdParty.jar"
          delegate="false"/>
</web-app>
(e) Change jvm12.conf file (for JNI)
It is located in
C:\iPlanet\Servers\https-yourserver\config
Add or uncomment the following lines:
#optional - just helps with instrumenting the jsp and servlet code
jvm.include.CLASSPATH=1
jvm.enableDebug=1
nes.jsp.enabledebug=1
jvm.trace=7
jvm.verboseMode=1
#required for JNI
java.compiler=NONE
jvm.classpath=.;C:\JDK1.3.1\lib\tools.jar;C:/iPlanet/Servers/plugins/servlets/examples/legacy/beans.10/SDKBeans10.jar;
jvm.option=-Xrs
jvm.option=-Xnoagent
# not sure if this is needed for iPlanet web server
jvm.option=-Djava.library.path=C:/iPlanet/examples/foo-dir/natlib/ -Djava.compiler=NONE
(f) Change magnus.conf file (for JNI)
We HAD to change this file in order for ThirdParty.jar file to pick up the native C++ code using JNI. Apparently, the
iPlanet Web Server doesn't pick the Environment Variable Path. Because when we had the directory containing the DLL just
in Path, it didn't work.
Change Extrapath directive:
ExtraPath C:/iPlanet/Servers/bin/https/bin;${NSES_JRE_RUNTIME_LIBPATH}
to
ExtraPath c:/iPlanet/examples/foo-dir/natlib;C:/iPlanet/Servers/bin/https/bin;${NSES_JRE_RUNTIME_LIBPATH}
(g) Apply changes from the Web Server Administration Console and Restart the web server.
You should be able to see the behaviour that you want from your application.
http://yourserver/foo/foo.jsp
Hope this was helpful!!!

Character Encoding for JSPs and HTML forms

After having read loads of postings on character encoding problems I'm still puzzled about the following problem:
I have an instance (A) of WL 8.1 SP3 on a WinXP machine and another instance (B) of WL 8.1 without any SP on a Win2K machine. The underlying Windows locale is english(US) in both cases.
The same application deployed as a war file to these instances does not behave in the same way when it comes to displaying non-Latin1-characters like the Euro symbol: Whereas (A) shows and accepts these characters as request-parameters, (B) does not.
Since the war file is the same (weblogic.xml, jsps and everything), the reason for this must either be the service-pack-level or some other configuration setting I overlooked.
Any hints are appreciated!

Try this:
Prefrences -> Content -> Fonts & Color -> Advanced
At the bottom, choose your Encoding.

JSP and Tomcat Problem

Folks,
My apologies if this is off-topic for this forum, but I've been having this problem using Tomcat and JSP. I'm fairly new to Java.
Basically, I'm writing a webapp that uses servlets and JSP together. The servlet and backend classes all compile fine. Now, basic frontend page is called Console.jsp, and one of the commands that it runs is <%@ page import="DJUser">
Here's the problem: Console.jsp is in $CATALINA_HOME/webapp/
DJUser (and the rest of the classes I'm using) are in $CATALINA_HOME/webapp/WEB-INF/classes
When I attempt to run Console.jsp I get this error:
exception
org.apache.jasper.JasperException: Unable to compile class for JSP
Generated servlet error:

I've been scouring the web for a while, and I can't really find anything on this. I'd appreciate any help you could give me.
Thanks!
Dylan

Put the DJUser java file in a package (say com.myClasses) and recompile. Then put the DJUser class file under the WEB-INF/classes directory in the proper package structure (WEB-INF/classes/com/myClasses/DJUser). Stop and restart the server to pick up the new classes. Make sure to change the jsp import statement ( <%@ page import="com.myClasses.DJUser">)

Help on JSP and Beans!

Hi! I am new to JSP and I need help on how to utilize java bean on JSP. I have gone through this forum, I found similar question but did not find any answer that could solve my question. Tons of thanks to anyone who could help me out!
I have a java bean class called Bean1, which I put under /ROOT/WEB-INF/classes/, and a JSP file that utilizes class Bean1, saved under /ROOT/, which should be a correct way indicated by several posts I found in this forum. But when I try to compile the JSP file over TOMCAT4.1 over http://localhost:8080/beanexample1.jsp, it throws me a lot of error messages (see below). I've been struggling for so long. Any help is greatly apprecitated! Thanks!

you need to put your bean in a package. do this by
making a sub directory under the classes directory,
let's say you call it "mybeans".
so copy Bean1.java to
/ROOT/WEB-INF/classes/Bean1.java
add the line "package mybeans;"
to the top of the Bean1.java file,
and then compile it there.
the standard way to use the bean in your jsp file is like this:
<jsp:useBean id="thisbean" scope="page" class="mybeans.Bean1" />
this <jsp:usebean> tag instantiates the bean for you.
then refer to it by its id:
thisbean.myMethod();
thisbean.setProperty();
I have a java bean class called Bean1, which I put
under /ROOT/WEB-INF/classes/, and a JSP file that
utilizes class Bean1, saved under /ROOT/, which should
be a correct way indicated by several posts I found in
this forum. But when I try to compile the JSP file
over TOMCAT4.1 over
http://localhost:8080/beanexample1.jsp, it throws me a
lot of error messages (see below). I've been
struggling for so long. Any help is greatly
apprecitated! Thanks!

Basic jsp and servlet question (JSP Model 2)

Hi
I want to make an website where i use JSP Model 2 architecture. However I got a basic question
1. I need to separate business logic from presentation with the use of jsp and servlets. Meaning I want no html code in the servlet. Can you give a simple example of how this can be done? If I map my implementation of httpServlet to a jsp page in web.xml and override doPost() and doGet(). The calls to the jsp page comes to the servlet as it should. I want to process some methods (calling sessionbeans or similar which in turn calls entitybeans) and then show the jsp page.
How do I show the jsp page without mixing html in the servlet as I've done below:
doGet(HttpServletRequest req, HttpServletResponse res)
PrintWriter p = response.getWriter();
p.print("<html><body>Hello world</body></html>"); //I dont want to do //this, I want to display the JSP site
doPost(HttpServletRequest req, HttpServletResponse res)
//doSomething
}Message was edited by:

You should treat your servlet class much like a controller, where you can then use JSP as the view. The way you achieve this is to use the forward() method in RequestDispatcher.
Say you've got a servlet class org.yoursite.controller.YourController:
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
//Set some value for use in the JSP file associated wth me
req.setAttribute("greeting", "Hello world!");
//Done with our business logic, off we go to the JSP file
ServletContext app = getServletContext();
    RequestDispatcher disp;
    disp = app.getRequestDispatcher("/some/jsp/file.jsp);
    disp.forward(req, resp);
}Now in your JSP file:
<h1>Example</h1>
<div>
I just want to say <%= request.getAttribute("greeting") %>
</div>Going to that servlet now executes business logic and then points to the JSP file for the view. You can forward from servlet to servlet too if needs be. The string you pass to forward() is whatever would be in the URI of the request so any <servlet-mapping> configurations in web.xml are used ;)
There is some pretty in-depth documentation on the J2EE blueprints website, namely service-to-worker and front-controller patterns. I dare say if you're looking for this sort of code you'll want to look at the composite view pattern too (also on blueprints).

Weblogic 10 jaas and login.jsp and web.xml/weblogic.xml security constaints

Hello,
I struggled through and got the examples.security.jaas.SampleCallbackHandler.java and examples.common.utils.ExampleUtils.java/ExampleConstants.java into eclipse where they compile. A bean I made can call SambleCallbackHandler like such:
mybean.logmein(username,password,url). I can then do a mybean.getStatus() or even a mybean.returnCode(). It does seem to correctly identlify that it is authenticating me (I see in stdout logs that it shows success or failures. The problem I have is I do not know how to apply this weblogic and web.xml/weblogic.xml so that if authentication works it redirects me to the page requiring the authentication. In web.xml I have the following set up:
<security-role>
     <role-name>Admins</role-name>
</security-role>
<login-config>
     <auth-method>FORM</auth-method>
     <realm-name>default</realm-name>
     <form-login-config>
          <form-login-page>/login.jsp</form-login-page>
          <form-error-page>/badlogin.html</form-error-page>
     </form-login-config>
</login-config>
<security-constraint>
     <web-resource-collection>
          <web-resource-name>empower</web-resource-name>
          <description>These pages are only accessible by authorized users.</description>
          <url-pattern>/admin/*</url-pattern>
          <http-method>GET</http-method>
          <http-method>POST</http-method>
     </web-resource-collection>
<auth-constraint>
<description>These are the roles who have access</description>
<role-name>Administrators</role-name>
</auth-constraint>
     <user-data-constraint>
     <description>This is how the user data must be transmitted</description>
     <transport-guarantee>NONE</transport-guarantee>
     </user-data-constraint>
</security-constraint>
My weblogic.xml has:
<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:wls="http://www.bea.com/ns/weblogic/90" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic-web-app.xsd">
<wls:security-role-assignment>
<wls:role-name>Admins</wls:role-name>
<wls:principal-name>Administrators</wls:principal-name>
<wls:principal-name>dashap</wls:principal-name>
</wls:security-role-assignment>
</wls:weblogic-web-app>
With this set up, if I try to go to a page in /admin folder in my application, it correctly pops up the login page. The jaas in the bean is doing a loginContext.login(), which I thought does authentication too, but it never goes back to the /admin page I was going to that needed the authentication. With jaas, can I not use the web.xml FORM security option? Do I Need to use j_security in the login.jsp's form's action= option and j_username and j_password for the input type names? How do I use j_username/j_password things if I am using jaas? I could just ignore using the web.xml security stuff and put something in the pages that need authentication, but it would be easier if I could use jaas with the security featurs without doing all that. Note that my code above is using a realm called default just because that was what was in the example I got from the web. Does that need to be something else?

Hi John,
I would like magic of course. However, in this case I want something special: my authentication provider uses special means and contents of headers, cookies and service from external identity management systems to determine the user's identity.
I do not want the application to present the login dialog! I want to derive the identity and the fact that the user is logged in from whatever the authentication provider returns in terms of Subject.
Ideally, the flow is something like:
- user accesses an unprotected resource - resource is shown, no interaction with authentication provider
- user presses a link or button that takes him/her to a protected resource
- the authentication provider is contacted to work with the identity asserter to establish the identity of the current user and create a subject object for this user
- the application can access the subject and principals
- ADF Security recognizes the identity and the roles (based on the principals) and coordinates access based on this.
the authentication method is client certificate. presumably this prompts WebLogic/OPS to use an identity asserter to work with custom headers and cookies ("... when you configure a web application to use CLIENT-CERT authentication. In this case, WebLogic can perform identity assertion based on values from request headers and cookies. If the header name or cookie name matches the active token type for the provider, the value is passed to the provider."). No login form should be presented to the user, as all information required to perform the authentication is already available.
I am trying to understand what I must do to have the ADF application adopt the subject set by the authentication provider - if anything?!
If you more ideas to share - I would love to hear them.
best regards,
Lucas

What's wrong with this ? Have you an idea ?
thanks in advance

Looks like the JSP compiler is failing when trying to figure-out (parse) one of your jsp tags. Try checking
line 73 column 59 in liste_diff.jsp, and see what might be wrong.
Good Luck.

JSP and CMP EJB 2.0

          Hi there,
          I having a problem every time I try to EJBHome.create( ...) a new
          CMP EJB 2.0 via a JavaBean
          called from an JSP or directly from the JSP.
          However, I successfully can retrieved EJBHome.findByPrimaryKey("myKey")
          from both the
          JavaBean and JSP.
          Could you help me figure out why .create does not work ?

Sorry but I have forgotten to precise that I have also developped a EJB CMP 1.1 where the bean class is not abstract and I have the same error when the JSP page calls this EJB
(for the EJB CMP 2.0 the bean class is declared abstract)

Jsp and corba :help !!!

Hi,
i am working about a web application which is willing to extend, so we want to fix in the cleanest way, the architecture. we think for example about CORBA, have you got a better idea, could you send me some addresses where i could find very clear examples about applications using jsp and corba or something else!
thank you very much if you can help me
cris

Hi bx1,
here iam giving you some example jsp with corba it will help you

Interesting single sigon application project using jsp and servlet....Help.

A customer login's to my website using Enterprise login. I am supposed to have a link on my website to this other website(that also uses our Enterprise login details but hosted by other vendor/company on their server), and when I click this link the customes should automatically get logged in to this other website and get a welcome page(instead of login page).
Below are the sequence of steps that the other website wants me to perform to get to his welcome page(i.e bypass his login page).
FYI, I am planning to build a jsp page with a link to this other website. Can some body tell me how should I build the application(i.e) how jsp and servlets be build to interact to perform these operations. Any hep is greatly appreciated.
1.When a user clicks on to other website link(available on my website), the browser generates an HTTP GET request to the Other website's session servlet. User's name is one of the parameters of this request.
2.Other website receives the HTTP request and generates a unique session identifier for this user. An HTTP response to the end-user is then sent. The user's name and the session identifier are passed back as parameters in the redirect URL.
3.The browser sends the HTTP request (GET) to the Verification Service that was specified in the redirect message. The parameters (user name and/or session id) will be passed as URL parameters.
4.The Verification Service(of other website) authenticates the user. A redirect URL to it's sigon servlet(with parameter's User id and key) is then sent back to the user's browser.
5.The end-user's browser will perform the redirect (performing an HTTP get operation to Other website's signon servlet with the username and the digest key).
6.The other website will check if the parameter's passed is the same as the one passed earlier, if the user is who he says he is then he is redirected to the main page of the application.
7.The browser will then redirect the user to Other website's main page (welcome.jsp).
There seems's to be many calls to this other website that needs to be performed behind the scenes once a user clicks the link on my website.
Please suggest and help me out.........

Why are you trying to build a whole federated single sign on framework from scratch when you can just use/buy an existing and proven solution instead? There are a lot of security implication and trust issues involved for this so unless you already understand all of those I'd advise you not to re-invent the wheel. There are a lot of products available that do this. Try searching for '<vendor name> Access Manager' or OpenSSO.

JSP and compiling

How do I get weblogic server not to compile the jsp at all and just use the class file that I generated from the JSP?


          There is a bug that was fixed in 6.1 SP3 related to the jsp dependency checker
          that was causing jsps to be recompiled when not necessary (i.e. when you'd already
          shipped a valid class file).
          The trouble with setting a working directory as described below is it tends to
          break badly when you want to release the same app across different OS - we develop
          on NT but run on Solaris, and D:\ means nothing there!
          So your best bet for jsp joy is to have your buildsystem precompile all the jsps,
          and upgrade to SP3 if you're still on 6.1
