Webflow vs. struts

Hi,
I am using portal 4.0 .
I am evaluating whether I can use struts frame work for "page navigation" rather
than "portal webflow". I would like to know how can I design a struts adapter
which will work with weblogic portal 4.0.
Any insight is helpful.
Thanks,
Gita

Hi Subbu,
as I mentioned before, am am aware of the other versions and
yes, I know about the 81 struts support :-)
But we are politically sticked to 4.0... So again, if somebody
has successfully wrapped struts into an older Portal version, any
guideline would be helpful.
Thanks,
Joerg.
Hi Joerg,
FYI, in case you've not already checked out, WLP8.1 supports
struts apps as is without migration. This support is available as
an add-on to WLP8.1 from dev2dev. With this approach, you
can continue to use struts for page navigation, but use WLP for
portlet aggregation.

Hi Raphaël,
I am not sure if you got into contact with Anju, but
nevertheless your adapter is exactly what I was looking
for.
We are migrating a Struts-based application to WLP 4.0
(yes, i know there is 7.0 and 8.1, but we have political
issues here :-) and in order to keep the migration time
as low as possible, the question of wrapping Struts into
Portlets came up.
The high level architecture in your ppt was pretty
straightforeward, so i would like to ask if you could
provide me with some examples for the components
you developed, like the struts-redirect-servlet and the
portlet which does the replacing of the html-part?
We have not started our development yet, so a short
code-insight to get some feeling for the amount of
work necessary would be great!
Thank you!

Hi anju,
I developed such an adapter to wrap your struts-based
application into a portlet without needing to use webflow
mechanism. Please see the attached file that explains
the philosophy.
I f you are interested to go further in in that direction, just tell
me. I will be happy to share technical details with others.

Is struts the preferred way over webflow for portal 7/8?

Hi:
I am a newbie learning more about the portal server product. I notice that
webflow is no longer included the document bundle of portal server 7.1 and 8.1.
Can I safely assume that the trend is to move to struts instead of using webflow?
Also, how does the portlet JSR fit in?
Thanks,
Keith

Problem with control hints and Struts tags

hi all. i'm using jdev 10.1.2 and JSP's. I was trying to set the format mask for a couple of number fields and ran into some trouble because; "JSP 1.2 prevents control hints from being used to set input element's display properties in a Struts input form". Has anyone found a way around this.
thanks

in your code, are you using the name attribute?
that's required:
http://e-docs.bea.com/wlp/docs70/jsp/navigat.htm#999781
there are examples of this tag in use...

RAD7 support for struts

Support for struts in RAD7 is added at the time of installation.But,
if support for struts was not addedat the time of istallation of RAD7(Rational Application Developer) ......, is there any way we to add support for struts,for developing struts applicaiton in RAD 7...?

Hi Ashish,
a brief answer, Portal 7.0 does not have the possibility to make usage of Struts within the Portal Framework.
7.0 has 'WebFlow' as a MVC pattern and you design your processing flow logic with the help of EBCC.
8.1 Platform and specifically Java Page Flow is based on Struts. Here you can make use of Struts Actions by Portlets and Portal applications.
Please see following links for some further information on Java Page Flow and Struts:
http://dev2dev.bea.com/products/wlworkshop81/articles/Dew.jsp
http://dev2dev.bea.com/products/wlworkshop81/articles/Feit.jsp
For your requirement I believe 8.1 would be a better choice.

Seeking solution in WLP for using MVC struts framework

Hi,
We would like to implement Struts like similar solution with Weblogic Portal Server.
I would like to know the possibilities of bringing the Struts framework in WLP
and I also would like to know the contraints in implementing the similar framework
in existing WLP.
Thanks in advance.

Hi Rathnakar,
In this very same newsgroup this subject has risen in september last year.
I include the posting, but admit that I have not tried it so far.

"Raphaël Faudou" <[email protected]> wrote in message
news:<[email protected]>...
I have not seen any official document on this integration but I personnaly
developped
a struts-portal adapter that allows a struts-based webapp to run as a
portlet
in the BEA portal.
The idea is to redirect the displaying
nstruction -requestDispatcher.forward(request,
response) - toward the portal webflow servlet with the appropriate
parameters
(portletName, pageName, event).
Remark : If you use struts 1.1, this adapter is very simple because you only
have
to inherit the RequestProcessor class and redefine the "doForward" method.
Then, you have two design solutions :
1) you model a simplified webflow with only presentation nodes and
transitions
that match what your navigation as specified in your struts-config.xml.
In this case, logic is handled by Struts framework and presentation is
handled
by the portal webflow servlet.
2) you dont' want to use portal webflow and you have to bypass it by
developing
another adapter at the portal side.
In this case, logic and presentation are handled by th Struts framework and
the
portal adapter only displays the next page in the appropriate portlet.
Conclusion : you can deploy a struts-based application in the BEA portal
after
developing one or two adapters that can be generic.
Good luck

Using a variable in Struts config, to redirect

In the struts-config file,
to redirect to a different site, I can use
redirect="true"
and mention full path, in my <forward path=
variable.
1. Is there a better way to do it?
2. Since I have to do it in multiple places, is it possible to use a variable? I mean, something like this
<forward
name="success"
path="URL/abc.html" />
Where URL is a variable name that the site path? This way, I can reuse the variable to redirect to other pages too (xyz.html, for example)

Hi there,
I don't know...is there only one URL you are using ore are there more than one? Because if it's the same path everytime you can try using this:
<forward
name="success"
path="./abc.html" />
./ // This is the shortcut for the directory you are currently using.
../ // This is the shortcut for the directory above the one you are currently using.This code should do it. If not, try to create a var named for example "vpath" and put it like this:
<forward
name="success"
path=vpath+"abc.html" />Try and tell if it worked ;)

J2EE Struts - Database connection failed - help???:(

Hello,
I have built a little web application and it works without any problems. In the next step I tried to add a database connection but I have already worked on it for at least one day and I could not fix the problem with the database connection.
I downloaded the MySQL Server 5.0 and installed it, furthermore I have downloaded the jdbc driver mysql-connector-java-3.1.11.zip and extracted it to the MySQL Server 5.0 directory. Furthermore I have added under system settings - system - etended - system variables the whole path to the driver -> C:\Programme\MySQL\MySQL Server 5.0\mysql-connector-java-3.1.11\mysql-connector-java-3.1.11-bin.jar to the CLASSPATH systemvariable.
Then I have startet the SQL Server 5.0 with mysqld --console from the command line.
Furthermore I have added under Project-Properties-Java Build Path - Libraries - Add External JARs in Eclipse the mysql-connector-java-3.1.11-bin.jar to my Struts WebProject.
To test the whole thing I have added to the existing test-database from mysql a table named owner and wanted to test the database connection in the Action-class with the following statements - I quote the whole execute method of the OwnerAction class:
public ActionForward execute(
                 ActionMapping mapping,
                 ActionForm form,
                 HttpServletRequest request,
                 HttpServletResponse response)
                 throws Exception {
               OwnerForm ownerForm = (OwnerForm) form;
               String greet = ownerForm.getGreet();
               String name = ownerForm.getName();
               request.setAttribute("name", name);
               request.setAttribute("greet", greet);
               String address = ownerForm.getAddress();
               String email = ownerForm.getEmail();
               int tel = ownerForm.getTel();
               Connection conn = null;
               Statement stmt = null;
               ResultSet rs = null;
               DriverManager.registerDriver(new org.gjt.mm.mysql.Driver());
               conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","sa");
               try {
                     //conn = dataSource.getConnection();
                     stmt = conn.createStatement();
                     int id = 0;
                     rs = stmt.executeQuery("select max(id) as counter from owner");
                     while(rs.next()){
                        id = rs.getInt("counter");
                     id += 1;
                     stmt.executeUpdate("insert into owner values("+id+", '"+greet+"', '"+name+"', '"+email+"', '"+address+"', "+tel+")");
                     rs.close();
                     stmt.close();
                     conn.close();
                  catch(SQLException e){
                     throw new SQLException("database error");
                  // Forward control to the specified success target
                  return (mapping.findForward("success"));
      }But when I execute the WebApplication and the Action will be called the following error message appears in the browser:

One thing I have forgotten - I have also copied the mysql-connector-java-3.1.11-bin.jar in the WebRoot\WEB-INF\lib directory of my EasyStruts WebApplication.

URGENT! Need help to portalize a Strut JSP App for Portal!

Hi,
I have create a little application using Strut ADF. This application only have one page. Can someone tell me how to portalize this in order to deployed it in Portal. I have create my DataSource in OEM and the only thing left is to portalize this jsp.
I have read the "How to create a Struts Portlet" but I don't understand it.
Please help me deployed this app to Portal. Is there any tutorial about this?
Thank you!

try this article
http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/articles/pdkstruts/portletize-your-app.html
You will also need to download the relevant tag library for the pdk-struts extensions.
You can also download the java portlet wizard as an add-in for jdeveloper. This makes the creation of the files (for example provider.xml) required by portal easier.

}Sorry for this stupid question, but how can i avoid this exception while using struts TagLibs?
I tried to face the jsp with another action, but this does not change anything.
Thank you in advance

New to Struts - logic:if error - am I not properly defining a bean?

I am going through what are for the most part simple Struts examples and tutorials on my company's Intranet. The example below should be testing against the pre-defined <logic:if> and <logic:or> statement values and spitting out either the 'one or more conditions are true' or 'none of the conditions are true' depending.
That said, I am getting an error with the following block of code (at line 11) just before the first logic:if statement and I am hoping for help in determining where I have gone astray.
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib uri="/tlds/marketmaker.tld" prefix="abc" %>
<%@ taglib uri="/tlds/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/tlds/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/tlds/struts-html.tld" prefix="html" %>
<%@ taglib uri="/tlds/jdo.tld" prefix="jdo" %>
<%@ taglib uri="/tlds/string.tld" prefix="str" %>
<abc:page>
     <h3>logic:if</h3>
       <logic:if name="calendarBean" property="month" op="equal" value="March">
       <logic:or name="calendarBean" property="year" op="lessEqual" value="2012"/> 
       <logic:or name="calendarBean" property="day" op="equal" value="Friday"/>
         <logic:then>
            <p>At least one condition above is true.</p>
          </logic:then>
          <logic:else>
            <p>None of the conditions are true.</p>
          </logic:else>
       </logic:if>
</abc:page>Again, the error is at line 11, occurring at or just before the <logic:if> statement. I presume it is because a bean must be properly defined.
I tried the following variations of <bean:define> and keep coming up with the same error.
<bean:define id="calendarBean" name="myCalendarBean" value="March" />
<bean:define id="calendarBean" name="calendarBean" value="March" />
<bean:define id="calendarBean" name="calendarBean"/>
<bean:define id="calendarBean" name="myCalendarBean"/>
<bean:define id="myCalendarBean" name="calendarBean"/>
<bean:define id="calendarBean" value=""/>
<bean:define id="calendarBean" value="false"/>
<bean:define id="calendarBean"/>Am I right about defining a bean first? If yes, what am I doing incorrectly in the aforementioned <bean:define> declarations listed above?
If you see something entirely different (and wrong) please do let me know.

Struts: getting multiple selected values from a select element

Hi Friends,
I am a total newbie with struts,I have manage to run a simple login script,
Now I was wonderingif there is a select box and user has the ability to select multiple values from it how do I get those values in the *Form class
my select tag looks like this
<html:select property="listboxValue" mulitple="mulitple">
...options--
</html:select>
in the ****Form extends ActionForm{....I have setter and getters for getting the value from select box as below
public void setListboxValue(String value){
this.listboxValue = value;
and the getter is
public String getListboxValue(){
return this.listboxValue ;
please never mind the missing brackets and such.
What I was hoping to get to work was something like this
public void setListboxValue(String[] value){
this.listboxValue = value;
but that does not work...If I have the an array being passed,it seems like this method is no even envoked
Please guide me
Thanks

I'm having trouble to get in the ActionForm all the selected values in my multiple select. I select all the values by setting to true the selected attribute of all the options in a javascript function. In the ActionForm the variable is String[]. I'm not getting any ClassCastException, but I only receive the first value selected (String array with just one element).
Select definition:
<html:select name="detalleConsultaForm" property="destinatarios" multiple="true" size="8" >
Javascript function:
function validalistarelacion(campo)
{ if (campo.length < 1)
alert("Campo sin valores");
campo.select();
return false;
for (var i = 0; i < campo.length; i++)
campo.options.selected = true;
return true;
ActionForm:
String[] destinatarios;
public String[] getDestinatarios() {
return destinatarios;
public void setDestinatarios(String[] destinatarios) {
this.destinatarios = destinatarios;
What I get:
2006-03-30 12:54:19,899 [ExecuteThread: '10' for queue: 'weblogic.kernel.Default'] DEBUG BeanUtils - setProperty(es.tme.apl.mante

How can I get the context-parm from a web.xml file using struts?

Hello:
I need get the context-param from the web.xml file of my web project using struts. I want configurate the jdbc datasource connection pooling here. For example:
<context-param>
<param-name>datasource</param-name>
<param-value>jdbc/formacion</param-value>
<description>Jdbc datasource</description>
</context-param>
and then from any Action class get this parameter.
Similar using a simple server can be:
/** Initiates new XServlet */
public void init(ServletConfig config) throws ServletException {
          for (Enumeration e = config.getInitParameterNames(); e.hasMoreElements();) {
               System.out.println(e.nextElement());
          super.init(config);
          String str = config.getInitParameter("datasource");
          System.out.println(str);
     public void doPost(HttpServletRequest req, HttpServletResponse res)
          throws ServletException, IOException {
          // res.setContentType( );
          System.out.println("Got post request in XServlet");
          PrintWriter out = res.getWriter();
          out.println("nada");
          out.flush();
          out.close();
but only this works for init-params, if I use
<servlet>
     <servlet-name>MyServlet</servlet-name>
     <display-name>MyServlet</display-name>
     <servlet-class>myExamples.servlet.MyServlet</servlet-class>
     <init-param>
     <param-name>datasource</param-name>
     <param-value>jdbc/formacion</param-value>
</init-param>
</servlet>
inside my web.xml. I need something similar, but using struts inside the action class for that I can get the context-params and call my database.
Thank you

To get context parameters from your web.xml file you can simply get the ActionServlet object from an implementing action object class. In the perform (or execute) method make the following call.
ServletContext context = getServlet().getServletContext();
String tempContextVar =
context.getInitParameter("<your context param >");

Values from JSP to Struts Action Class

Dear All,
Am working on a small struts project, i want to get values from JSP in the Action class, i tried with sending variables using request through URL, it works fine, any other way is there to send the values from JSP to action class. Am not having any input fields in the JSP.I have links.
Thanks,
vyrav.

I have a dispatch action for that am calling the action like this viewfiles.do?parameter=edit, and i have to send a variable ID from the same page, so am doing like this through java script, viewfiles.do?parameter=edit&id=10. Am able to get the id in the dispatch action edit, but when i start tomcat with security manager its not calling the action itself and its giving accesscontrol exception, but when i directly type viewfiles.do in URL its calling the action.
I dont know wats the problem, tomcat security manager not allowing this. Please help me.
Thanks,
vyrav.
