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 >");

Issue in converting Struts view to JSF view using struts-faces integration

Hi All,
I am facing a issue in my Sruts to JSF conversion application using struts-faces.jar integration library.
Need expert's help desperately as I am not able to use <s:form> tag in my new jsf page to call a struts action.
I want to call a struts action from my web page designed using JSF,
but it seems impossible without using <s:form> tag from struts-faces integration library.
Please suggest how to resolve this...
I am using WSAD 5.1 IDE with inbuilt Test environment WebSphere server
JSF Version: Sun's RI 1.1
Struts framework: 1.2.6
Struts-Faces Integration Library version: 1.0
I have configured a controller element in struts-config.xml file as has been suggested by different online
documents I studied:
<controller>
<set-property property="processorClass"
value="org.apache.struts.faces.application.FacesRequestProcessor"/>
</controller>
But configuring a controller does not allow my test server to start up properly and due to errors the ActionServlet also becomes unavailable.
If I comment the controller and start the test server it starts fine but then I cannot access the converted jsf page which contains the <s:form action="/xxxxx.do"> tag.
If now I get back to <h:form> tag instead of <s:form> tag with a <h:commandButton action="xxxx.do"/> for form submission in my jsf page, I see the html page generated with all components but now checking the html source generated I see
<form action="/contextName/jspFolder/sameDisplayedPage.jsf"> which is not valid and never gets called successfully.
I think someways I need to use the <s:form> tag with the controller configured properly to use the struts-faces integration library's request processor, to get things working. But HOW???
Following is the error I get if I use the <controller> tag element in struts-config.xml file and start the server.
This error appears on starting the server without accessing any application's jsp web page

Finally if I change my <s:form action="xxxxx.do"> tag to
<h:form>
<h:commandButton id="submit" action="xxxx.do" value="Submit" />
I see the webpage coming up in the browser (no controller element used in struts-config.xml file this time)
But in the html source of this html created from jsf I see
<form id="_id2" method="post" action="/training2/jsp/welcomeF.faces" enctype="application/x-www-form-urlencoded">
here form's action attribute is pointing to the same displayed page with the context name prefixed. I
assume it is because jsf could not resolve the "xxxx.do" action to anything so set it to the same displayed page.
May be I am wrong as usual...
Below is the simple struts jsp page which I need to convert to jsf page as I am converting only the View part of application.
I want to use the same struts beans and application logic at the back-end. At front-end I need UIComponents from JSF to be used.
Following is the struts jsp page

</html:form>

I have converted it into the following jsf page

I am in urgency of course but would not push for immed. response like other, just want some help for sure that is going to
be extremely valuable to me. Anticipating a helping hand...

I've managed to get this working Ok from JDeveloper:
See:
http://www.groundside.com/blog/content/DuncanMills/J2EE+Development/?permalink=573FDB6F8D918B9704907899635CABB1.txt
http://www.groundside.com/blog/content/DuncanMills/J2EE+Development/?permalink=2B04ACE99A6437EDED775F15553D1DED.txt
Basically you just have to fiddle around with Library settings to get this working OK.
As to how useful this is, well that's up to you - I'd not regard Faces + Struts as a must use combination, rather it's a can mix if you really need to. Look at Faces and Faces navigation first and see if that actually gives you enough before you start to look at mixing.

How to create menu bar in jsp page using struts-tles

I have started working with struts-tiles. I want to create menu bar using struts-tiles. please guide me.

I've done this very recently. In fact, tiles has very little to do with the menu itself.
In your layout, define where you want the menu to go.
<tiles:insert attribute="menu" />Now, in the actual file, create your menu structure. This part is up to you. I've used http://www.brainjar.com/ as a starting point for the client side actions.
On my menu page, I call a method on a custom object that returns the menu bar object. Currently, I'm working on putting this menu into some sort of cached object so it doesn't have to rebuild it on every page request.
Perhaps I've misread your post and you're looking to use tiles, in and of itself, to simulate menus? Otherwise, I hope my post helps.

Collection in collection using Struts

I know we can submit the value of value object in collection using the following code.
<logic:iterate id="collection" name="form" property="collection">
<html:hidden indexed="true" name="collection" property="code" />
</logic:iterate>
But how about collection in collection? Is this possible in struts?
Thanks in advance

What you say is indeed the way to use struts.
But I dont want to define in my jsp which fields of the Company object I want to display. I just want to loop through array of Collections and display them on my screen.
I would like to ask the EJB for example getCompanyByName which returns me a array of Collections : (Company a, street 1) , (Company b, street 2)
If I call getCompanyByStreet it returns me (street 1, Company a), (street 2, Company b)
Thanks

Yes, you could try using the multipart handler...
But I have a better idea...
Determine the maximum number of file uploads that the
user can do at one time. I mean, you can't
realistically have the user upload a million files at
one time. So say the max is 20. So you create your
action form class with 20 FormFile fields called file1
to file20.
Then when you dynamically create your page, you
dynamically create the specified number of file fields
and 1 hidden field called "totalFiles" which contains
the number of file fields you created. This should be
an int field in the form bean.
Then when you do your action processing, you just loop
thru the totalFiles... Or well, actually, you may not
need that at all. You could just check all the
FormFile fields and whatever ones aren't null contain
files.But what about UploadActionForm.java[b]
How do i have exact mapping of the HTML form in this file ??

Calling DB from Struts

Hi All,
I would like to access Database from struts without using EJB, Pl. advice which architecture is best
Thanks

Dear dsn29:
There are basically 2 ways to call databases:
1. To call using JDBC directly
2. To call using a database pool connection
Using the 2nd one you can use:
a) Struts own connection pool,
b) the server application server connection pool if it has one,
c) a connection pool implementation ftrom a 3rd party like jakarta db connection pool.
Which one is the better one?
Well depend on how you like to code or deploy. The thing I have noticed is that Jakarta connection pool works very well and it is very independant. The only problem is that you have to define the connection either on tomcat's server.xml or in the META-INF/context.xml.
Using the connection implementation that comes with the server like Sun App Server 8.1 Q12005, is that you have to install the driver in the domain/lib/ext directory, you have to define the connection correctly at the first time (the server must recognize it to show all the drivers parameters) or you will always get a bad ping. And there are several problems with the Sun's implementation that they haven't answer back. For me the connection pool was been a pain in the neck (just search from lorenzosjb username to see). Just look my last: http://forum.java.sun.com/thread.jspa?threadID=612144&tstart=30
Finally, Struts own implementation connection pool you have to configure using the config-struts.xml . Goto to www.wrox.com and download the source code for Professional Struts (James Goodwill and Richard HighTower) and you can purchase this excellent book . The db connection pool is on chapter 11.
You can also go to http://www.objectsource.com/ where you can download a free book called Struts Best Practices that can help you
And you can www.theserverside.com and download Jakarta Struts Live and Servlets and JavaServer Pages: The J2EE Technology Web Tier for free: http://www.theserverside.com/books/addisonwesley/ServletsJSP/index.tss that can help you more.
So now I am also investigating, using Struts db implementation and installing the test web application in several java application servers to see if the implementation is really independant.
You I helped you, and good luck!

Lorenzo

Can we use Struts 1.2.8 with Oracle AS 10.1.2?

Hi all,
May I know whether we can use Struts 1.2.8 under Oracle AS 10.1.2? Does it conflict with any library used by Oracle AS 10.1.2 already?
Thanks and regards,
William

Hi William,
I am using Struts 1.2.8 in Oracle JDeveloper 10.1.2. I face no problems with it. But make sure that yor are not adding the Library called Struts Runtime provided by JDeveloper to your project. Just add the Srtuts 1.2.8 jar files to you Project Additional Classpath or go to Tools --> Manage Libraries and add these Struts 1.2.8 jar files there and use this in your Project Libraries.
Hope it helps,
Cheers,
Aravind.

Question of using Struts for the J2EE pattern

I am now using Struts for the development. I have 3 questions about J2EE
pattern by the use of Struts:
1) How can I use Struts to create the Front Controller? In the book
descibing Front Controller, it is a servlet file which receives the request
and then dispatches to the appropriate view according to the request.
However, in using Struts, should I use the same way? However, I found that
in using Struts, I can call the controller class which subclass
ActionServlet, all the views forwarded are declared in the
struts-config.xml. Am I right in this method?
2) In the project, there is a Front Controller which dispatches the request
to the appropriate view (jsp file). Of course, I use Struts to do this.
However, I expect that the user is impossible for going to the view (jsp
page) directly by typing the address of the jsp file. I hope that the user
can go to the view through the controller only. How can I do this?
3) There is a problem by using browser - when a user browses a site, he can
press the 'back' button to the previous page, and then click the 'forward'
button also. How can I prevent this by using Struts? I found that in some
sites, when the user clicks the 'back' button, an error page displays. How
can I do this? Thanks!
Many Thanks!
Stephen

I'll take a stab at number 2 and number 3.......
2) You could have the controller object place a "flag" in the request that is dispatched to the JSP. Make the JSP check for that flag to ensure that this request came from the controller object. If the request comes from anywhere other than the controlle object, you can display an error page, or you could redirect them back to the controller. You could also use the HTTPSessionObject to place flags for users and have the JSP check there.
3) Keep a log of the user's activities in the HTTPSession. Whenever a page is invoked, have it check to see if the user has already been here, and if it is appropriate for the user to be here again.
Hope this helps!!

How to "Performing an Action on Multiple Selected Records" using Struts-JSP

Hi all:
How to do "Performing an Action on Multiple Selected Records" through using Struts/JSP solution that is original MVC/UIX customizing example by Jheadstart.
I know how to reason by analogy through tutorial guide on
Model and Control layer of MVC , but for View layer that is torment to me !
have any idea ?
thanks a lot .

Ting Rung,
In the table in the JSP page you add a checkbox like this:
<td class="fixed">
<input type="checkbox" name="multiselect" value="<%=index%>"/>
</td>
This will render a checkbox in each row, with index number of that row as value.
When you submit the page the request contains the multiselect parameter when at least one row has the checkbox checked.
You can get the value of the multiselect parameter by calling sessionData.getRequestParameterValues("multiselect") in your action. The value is a string array containing the index numbers of the rows that have the checkboc checked.

Receive POST data from another URL and process using Struts

Hi there
We have a website and as of now we are receiving some data from another URL which is received as an appended part of the URL. My application uses Struts and we process the received data and send back a response.
Now my question is, I have been asked to change this behavior because there are more parameters now which cannot be passed through the URL. I am supposed to get the data from the other URL as POST data (as a form) and I have to create a new Struts action to receive this data, process it and send the response back to the requesting URL.
Please explain me how to do this using some example code snippets.
Thanks a lot

Lookup in XI is used to call the target data storage system and get data from there to your mapping programme.
In XI you can do Lookup in Message Mapping, Java Mapping and in XSLT Mapping. Previously Lookup in XI was system dependent. But now what ever the system are i.e. SAP system or non-sap system(Oracle,MS SQL etc) lookup API are same.
Overview of Lookup
- Lookups are used to identify/request the data from mapping program.
- It interrupt the process and looking for data which was stored in target system.
- It get that data and comeback to process and continue with that data.
Types of Lookups in XI
- JDBC Lookup: JDBC lookup is used for accessing data from database (non SAP).
- RFC Lookup: RFC lookup is used for accessing the SAP Data.
- SOAP Lookup: SOAP lookup is used for accessing data from Webservice
Steps to perform Lookup in Mapping
Import package com.sap.aii.mapping.lookup.*;
Create connection to the target Database system.
// Determine communication channel created in ID
Channel channel = null;
channel = LookupService.getChannel("DB-SYSTEM-NAME","DB-CHANNEL-NAME");
// Get system accessor for the channel.
DataBaseAccessor accessor = null;
accessor = LookupService.getDataBaseAccessor(channel);
Build the Query String.
Getting Result
// Execute Query and get the values.
DataBaseResult resultSet = null;
resultSet = accessor.execute(Query);

Double submit handling using struts tokens

Hi,
I am using struts token to handle double submit.
The way i have implemented is,
wrote a base Action class.
Inside the BaseAction class i have overriden the resetToken method like this,
synchronized public void resetToken(javax.servlet.http.HttpServletRequest request) {
     javax.servlet.http.HttpSession session;
     session = request.getSession(false);
     if (session == null) {
     return;
     session.removeAttribute("org.apache.struts.action.TOKEN");
saveToken(request);
I m calling saveToken inside resetToken for new pages.
So how it would work is first time in my action i would call saveToken which would set token in my jsp page and then in respective actions i would check if isTokenValid(),
and then call resetToken so that i would clear the old on and set the new one for the new jsp page.
Is that the right way i m doing it ?
Please suggest me if there is better way to handle it.
Thanks
Abbyss

You can use isTokenValid(request, true) which will automatically call resetToken() after checking the token.

Incoming calls not using Bluetooth / Music tracks repeating

I've been having a problematic issue with Bluetooth since upgrading to iOS 7. I have my iPhone 5 paired with my 2013 Hyundai Elantra's Bluetooth system.
Outbound calls use Bluetooth just fine, as does Siri, but any incoming calls all use my iPhone's headset by default. I have to manually switch the phone's output back to my car's bluetooth in order to talk using my car's hands-free system... which really defeats the purpose of hands-free.
I'll note that this is happening both when my iPhone is plugged in via USB and listening to music on the car's stereo, as well as when the iPhone is simply idle in my pocket. I have not tested what happens when the car is playing my iPhone's music via Bluetooth (the audio quality is sub-par to a direct connection and doesn't display the artist/track/album on the console when playing via Bluetooth - ergo I rarely use it)
Secondly, I am having another issue, this time with playing music. I don't believe it's related to the above Bluetooth issue, but it may be related to my car.
Like I said above, I often use my Elanta's USB port to directly plug in my iPhone so I can a) listen to music on the car's stereo and b) skip tracks with the wheel-mounted controls. This all worked flawlessly with iOS 6.
Now, if I skip a track with my car's controls, the Music app will repeat that next track... over and over. When the song is completed, it will attempt to move on to the next song, then immediately backtrack and start playing the previous song again (you can tell so by watching the Music app. The album art will swipe over, then quickly swipe back). I have to manually skip forward to play a new song... Highly irritating.
I'll also note that skipping songs via the wheel-mounted controls is considerably slower than it was with iOS 6. It's definitely a couple seconds after I press a button before the next song starts to play. It used to be near-immediate.
Anyone else having either of these issues? Hopefully it's something Apple picks up on and fixes soon!

Don't know if you got this yet, but I came here looking for answer. Since I just found one, figured I'd pass it on for others:
You have to set your phone's incoming calls to "headset" under accessibility. (Silly, I know, considering, if you hook up a bluetooth, it should automatically default there, but no ...) This walks you through:

Cannot receive calls when using Edge network for data?

Hi,
This afternoon someone was trying to reach me urgently and all her calls to my iPhone went straight into my voicemail. My phone never rang and never showed missed calls.
I spoke to Aaron at Apple, thinking there might be a problem with my phone, and he told me that when the Edge network is in use, then the phone will not ring and calls will be routed straight to voicemail.
Is this really expected behavior? I was not aware of it.
iPhone 8GB

This has nothing to do with EDGE all other phones will notify you and pause the connection. i posted about this 2 days ago but the thread got deleted.
here is a video that proves this, the noise is from the GSM but the user is clearly on the edge network.
http://youtube.com/watch?v=NMm2AY-_TTY
this is from Tier 2 suport at Apple.
Everyone having this issue should call 1-800-MY iPhon. Ask to speak to Tier II support, the person you get may try to help, and may need to give you a case number. You'll probably have to wait a while on hold.
I just spent an hour on the phone with Tier I & II. The tier I guy started by saying that when you use EDGE it will always go to voicemail. I told him, I was on a user forum & some people said they don't have the issue. He then tested it on his phone & experienced the direct to v-mail issue. We talked about how this was a real problem & how both of our nokia phones didn't have this issue (he actually had the E-61 also). He gave me a case number & transferred my to tier II. The tier II guy told me that this was a software issue. That a pop-up needs to be designed into the software to allow the user the option to disconnect the data connection & accept the voice call, or not. I told him that I'd read on a user forum that some users get voice calls while using EDGE. He said that if they are using you tube the call will automatically interrupt & switch out of you tube. We then tested this on my iPhone & it worked (i.e. the call interupted you tube). He said the software currently decides to disconnect data or send calls to voice mail during EDGE transmissions based on what the user is doing. Phone calls take priority over you tube & widgets (stock & weather)but safari and e-mail take priority over phone calls. He said the thought was, it would be more annoying to users to be in the middle of sending an e-mail and having mail disconnected for a phone call, than having the call go to voicemail. The ideal solution is to have a choice (like other phones allow) but right now the iPhone software does not have a pop-up designed allowing the user to accept the call or keep the data connection. (He seemed to be familiar with this on other phones while being tethered to a macbook to use their data connections & getting voice calls during downloads).
He said he was submitting this to the engineering group & said the more people that call tier II about this & submit it as an issue via online feedback, the higher priority it will get to be addressed in the first software update. So if you want to see this fixed start calling and submitting the issue http://www.apple.com/feedback/iphone.html in as much detail as possible (specifically say that other existing phones Nokia S60s etc. have this function).
and here is a thread that is discussing this serious problem. note it is now many pages long.

When I call someone using FaceTime from my mac, they can see me but no hear me. Is there something I need to do to make this happen? I also have an iPad 2 and FaceTime works great on it if I call somebody. Why no sound from my mac FaceTime using a mac pro

When I call someone using FaceTime from my mac, they can see me but not hear me. Is there something I need to do to make this happen? I also have an iPad 2 and FaceTime works great on it if I call somebody. Why no sound from my mac FaceTime using a mac pro and isight camera, mike combo.
If I use google it works. If I use Ichat, it works. If I use skype it works.

This sounds like something similar to https://discussions.apple.com/thread/3388112?start=105&tstart=0.
Try turning down the speak volume (System Preferences->Sound->Output->Output Volume) or the microphone gain (System Preferences->Sound->Input->Input Volume). Do this on both sides of the call.
