How to call another action from Struts dispatch action?

Hi all,
there is a method in dispatch action that needs data from another chained action. How should other action determine which method in dispatch action will receive response and how should these data be returned from called action? Called action does not have associated form bean
thanks,

Not sure, why are there then "chained actions" is struts practice? Struts allows action without form bean to be configured and the action is a class?

Dispatch Action

Hi how to use DispatchAction in struts

Hi,
Whenever working with dispatch action, while specifying its button name or link name specify an attribute called "property", give some logical name for this attribute and in struts-config.xml, the same attribute with logical name should be used. so when ever u send multiple requests with in a same page , it gets processed, do not forget to implement ur methods with same execute() signature.

In Web Logic Server Due to HTML file tag the action of struts is not called

Hi All
I have a problem as under:-
There is a HTML page which contains several fields including a file input tag of HTML and i write enctype = "multipart/form-data" in the form tag
I am calling a struts Action from this form, then it is not reaching to that action of struts.
If I remove this file tag and enctype = "multipart/form-data" then it reaches to the struts action.
I am facing this problem in Weblogic server 8.1 but i can easily deploy this same code on Tomcat 5.0
Please help me out from this problem..
Thanks...

Struts input forward using dispatch action

I have a insert jsp and another update jsp but one action with the dispatch concept named daction.In case of errors i forward using input forward(), but in config file i have can specify only one path in
<action input ="/insert.jsp"/>
but in case for the update error to pass to update.jsp how to handle...........

request.getRequestDispatcher("reqresAction.action").forward(request, response);It's right.
But I believe you forgot about a tag like <dispatcher>FORWARD</dispatcher> in your <filter-mapping>(web.xml).
I use a rediration from servlet to action and it works fine.

Passing value from JSP to Action in Struts

Hi,
I am populating JSP page with rows retrieved from the database and
represented as a List of Beans in forEach loop:
<c:forEach var="list" items="${OperationsForm.OperationsList}">
<c:choose>
<c:when test="${list.isCompleted =='Y'}" >
<td width="100">Completed</td>
<td width="100"> </td>
</c:when>
<c:otherwise>
<td width="100">Pending</td>
<td width="100"><input type="image" onclick="
rowId=value; form.action='action.do?command=notify'"
value="${list.OperationId}" />
</td>
</c:otherwise>
</c:choose>
</tr>
</c:forEach>
Have hidden field: html:hidden property="rowId" value="-1"/>
User is clicking the button corresponding to one of the rows
and I need to pass the value of that rowId to the Action class, so it does
something in the database [action completed]
Now how do I pass it , is that the right way of doing it with calling
request.getSession().getAttribute(rowId) in the Action class ?
As of now I am getting Javascript error "Object doesn't support this
property or method", complaining about rowId=value;
Using Struts 1.3
Please help !
TIA,
Oleg.

So what you are saying is that I should add rowId here:
<input type="image" onclick="form.action='action.do?command=notify&rowId='
${list.OperationId}"/> , correct ?
I am not sure that it will work, especially with Struts tag.
I will probably try something like:
<html:submit onclick="form.action='action.do?command=notify'" value="${list.OperationId}">
I am relatively new to Struts, so now sure what will work or not and how to do it better. How do I catch the submitted value in the Action in either of these 2 cases, via action.getSession().getProperty("rowId") /
action.getSession().getProperty("submit") ?
I would probably do it as a URL rather than changing the action of the form.I will have to create a new action anyway to process that row [which is sending user e-mail regarding that row data/event].
Is the id the only thing you have to pass in?
Or do you need other values from the screen?Selected rowId is probably the only thing I care about, can access values from the Form in Action.
Thank you,
Oleg.

Query regarding Declarative exceptions in struts

Hi all,
I am using decalartive exceptions in struts,
My struts-config.xml is as follows -
<action
path="/tryexception"
<exception
type="hansen.playground.MyException1"
key ="errors.exception1"
handler="hansen.playground.MyHandler"
path="/error.jsp"/>
</action>
Currently i am displaying the error message in my error.jsp page by getting the value from the session.
The code is as follows -
<%@ page language="java" %>
<%@ page import="java.util.*" %>
<%@ page import="java.io.*" %>
<%@ page import="org.apache.struts.*" %>
<%
Enumeration paramNames = request.getAttributeNames();
while (paramNames.hasMoreElements()) {
String name = (String) paramNames.nextElement();
     if (name.equals("errorMessage")){
          Object values = request.getAttribute(name);
          out.println("<br> " + name + ":" + values);
%>
This works fine and the error message is diplayed.
My question is there any other way to display the error message in the jsp page without getting it from the session.
Any suggestions will be appreciated
Thanks,

You could simply POST the data as opposed to using GET. Though it doesn't encode/ encrypt the data, but simply adds the parameters into the body of the request. If someone were to look at your requests, they'd be able to see this data.
As for actually hiding it through encryption, you could get JavaScript libraries to do this on form submit but I doubt you'd need that much security. You could also try base64 encoding for a simpler approach.

Regarding Connection Pooling in Struts

Hi All,
I m using Struts for my web application. Now I want to use the Connection Pooling for my applicaiton.
I m using JBoss, and Oracle 10gXE.
My question are :
1. Do I need to use Oracle Specific Connection Pooling or commons DBCP & Pool.
2. Do I need to JNDI to bind my data source using mydatasource.xml in deploy folder of JBoss or
define the datasource in struts-config.xml of my application.
Which will be the efficient way?
Presently I m defining my datasource in struts-config.xml. like :
<data-sources>
     <data-source type="org.apache.commons.dbcp.BasicDataSource" key="msgds">
          <set-property property="description" value="OracleXE Data Source" />
          <set-property property="driverClassName" value="oracle.jdbc.OracleDriver" />
          <set-property property="url" value="jdbc:oracle:thin:@192.168.1.8:1521:XE" />
          <set-property property="minCount" value="2" />
          <set-property property="maxCount" value="50" />
          <set-property property="maxWait" value="5000" />
          <set-property property="username" value="ashish" />
          <set-property property="password" value="ashish" />
          <set-property property="autoCommit" value="true" />
          <set-property property="readOnly" value="false" />
     </data-source>
</data-sources>
3. How can i change it to an mydatasource.xml for JNDI. If is it like this,what is the error:
     <datasources>
       <local-tx-datasource>
         <jndi-name>msgds</jndi-name>
         <connection-url>jdbc:oracle:thin:@192.168.1.8:1521/XE</connection-url>
         <driver-class>oracle.jdbc.OracleDriver</driver-class>
         <user-name>ashish</user-name>
          <password>ashish</password>
         <min-pool-size>5</min-pool-size>
         <max-pool-size>100</max-pool-size>
       </local-tx-datasource>
     </datasources>Please if somebody have idea of it, plz help. If U have code for this plz send it to me.
If u don't want to publish you can send it to my email id: [email protected].

Just make sure all the JARS are in the classpath. BTW I use Iplanet but does that matter much ? Configure the Struts-config file for the datasource by adding the below tag text.
<data-sources>
     <data-source type="org.apache.commons.dbcp.BasicDataSource" key="DBSTR">
          <set-property property="description" value="OracleXE Data Source" />
          <set-property property="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
          <set-property property="url" value="jdbc:oracle:thin:@155.136.118.169:1521:DBSID" />
          <set-property property="minCount" value="2" />
          <set-property property="maxCount" value="10" />
          <set-property property="maxWait" value="10000" />
          <set-property property="username" value="USER" />
          <set-property property="password" value="PASSWORD" />
          <set-property property="autoCommit" value="false" />
          <set-property property="readOnly" value="false" />
     </data-source>
and then access from your action or servlet by executing the below java code.
dataSource = getDataSource(request,"DBSTR");
conn = dataSource.getConnection();
stmt = conn.createStatement();
rs = stmt.executeQuery("select object_name from user_objects");
while ( rs.next() ) {
tmp = tmp + ": " + rs.getString("object_name");
Piece of cake.

BUG? Data Action on Struts changing to Data page when i reload Jdev????

Hi All,
i'm using jdev 10.1.2, adf bc's, struts, jsp's.
I have a data action on my struts page which is bound to a method in the app module. I created a class for this data action which overrides the initialMethodParameters() method and gets the arguments for the method in the app module.
it all works perfectly fine, until i come into work the next day, load up JDev and the data action has now turned into a data page. if i dbl click on it i get the create page dialog, instead of the data action class. obviously when i try run this data action, i get cannot display this page error.
I'm assuming/hoping that this is a bug. can anyone shed any light??
Thanks in advance,
Liz

Hi,
did you open this in the same version of JDeveloper 10.1.2? I remember that there was a change in Struts between JDeveloper versions

Servlet and Actions - Apache Struts !

Hi,
i defined an ActionServlet in the web.xml and some "Actions" in the struts-config.xml.
If all the requests are managed by the servlet defined in the web.xml, in case i had a lot of requests would it be better defined more ActionServlet in the web.xml which refers to different struts-config.xml ?
I think that having more servlet is much better to manage the load of the entire application.
Any suggestions ?
Cheers.
Stefano

No need creating more than one ActionServlet : Servlets are Threads so each request made by a client is handled by a different Thread!

Regarding google map with struts

Hi,
Iam developing small application for connecting to google map by using struts and hibernate,Am taking two parameters country and location by using these two parameters how can i connect to google map?

What does a typical "location" look like? Is it an address? A town name? And I can assume country is a 2-digit ISO code for a country?
You could try something as basic as:
URL url = new URL("http://maps.google.com/maps?q=" + location + ",+" + country);
and see if that works.
