Bc4j/struts/validator integration
Hi,
I try to integrate the Validator framework (which is included in the standard struts-blank war file) with a standard "struts-based JSP for Business Component", adding the plugin in the struts-config.xml, and the validation.xml/validator-rules.xml in the web application.
I catch the follow:
[INFO] ValidatorPlugIn - -Loading validation rules file from '/WEB-INF/validation.xml'
java.net.ConnectException: Connection refused: connect
void java.net.PlainSocketImpl.socketConnect(java.net.InetAddress, int)
boolean oracle.xml.parser.v2.NonValidatingParser.pushExternalDTD(java.lang.String, java.lang.String)NonValidatingParser.java:521
void oracle.xml.parser.v2.NonValidatingParser.parseDoctypeDecl()NonValidatingParser.java:448
Thanks in advance,
Marco

BC4J/Struts Integration classes
Does anyone know of any documentation on the BC4J classes that are used in Jdeveloper for struts integration?
I have access to the source that came packaged in jdeveloper but I still have questions about the classes BC4JActionMapping,BC4JRequestProcessor,BC4JActionForm,BC4JUtils,BC4JContext, and HTTPContainer.
One of my initial questions is whether I should specify the view object name I'm using in an action in my struts-config.xml file as I do with the application module? Also, when I do this how do I programmatically access it.
I'm also interested in how the BC4J Client Data Model ".cpx" is used and if this needs to be packaged when deploying a bc4j/struts web application.
The postings at Re: re:Using Struts without Datatags <jbo:xxx> by Steven Muench were terrific. A great start for understanding the integration of the two technologies. I would just like more detail on how/why bc4j leverages struts extension points.
Thanks in advance!part 2 of posting:
<action path="/navigateEmpView1" parameter="jboEvent" type="oracle.jbo.html.struts11.actions.NavigationAction">
<set-property property="viewobject" value="EmpView1"/>
<set-property property="application" value="Mypackage1Module"/>
<set-property property="releasemode" value="Stateful"/>
</action>
Since NavigationAction is a Struts DispatchAction (instead of calling the execute method on the action, the method name to execute is passed using a request parameter), you will need to specify the event name on the request with the URL:
/nextEmpView1.do?jboEvent=next
To understand how this work, you need to look at how the BC4JContext is initialized:
The following code is extracted from BC4JrequestProcessor:
BC4JContext context = (BC4JContext)request.getAttribute(BC4JContext.ContextAttrName);
// Instantiate the context and save it on the request
if (context == null)
context = new BC4JContext();
request.setAttribute(BC4JContext.ContextAttrName, context);
if (initPageFromPath(bc4jMapping, request, response))
// First initialize context with the existing mapping values
bc4jMapping.initializeContext(request, response, context);
// Then use request para[i]Long postings are being truncated to ~1 kB at this time. -
We're developing an ADF/Struts app.
We started off with entity object level validation. However, we'd like nice formatable messages so decided to move towards Struts form beans and perform validation there.
Firstly, was this the right thing to do or can we place and format entity object validation errors however we like?
If we did make the right choice we aren't sure how ADF bindings and form beans interact and whether they should be used together.
We ask because of the following:
If we add a getFirstName field onto the form bean, and call the field in the JSP firstName (lower case 'f') then all is well and the form bean operates as expected with no errors.
However, if the field on the JSP is called FirstName (capital 'F') then the getter method is not found:
"No getter method for property FirstName of bean org.apache.struts.taglib.html.BEAN"
ADF bindings give the JSP properties upper case first-letter names by default. We can of course go and rename all of the bindings - but that's time consuming and as nobody has complained of something similar in the forums, we get the impression that we're doing something wrong or that they are rarely used together.
Any help appreciated.
BenThe general rule with validation is never to rely on the UI generation layer to validate your data.
It's reasonable to place validation there, but you should back it up with validation on the EO as well.
If you want to mix Struts validators with ADF bindings then you're best using the Struts Validator framework and the oracle.adf.controller.v2.struts.forms.BindingContainerValidationForm as the type of the Form Bean for that page. That way you can use both ADF bindings and declaritive validations using the validator XML definitions -
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:submit property="submit" value="Show info via Struts" />
</html:form>
</BODY>
</html:html>
I have converted it into the following jsf page

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. -

Can't get Struts validator to work with ADF 10.1.3.36.73 in Jdev 10.1.3.0.4
I am attempting to use the "How to Use the Struts Validator Plug-in with JDeveloper 10g" written by Duncan in a JDeveloper 10.1.3.0.4 application with standard model/ViewController projects. I am using JSP/Struts/ADF technologies.
I have performed the below:
Struts Config:
<form-bean name="surveyDataForm" type="oracle.adf.controller.v2.struts.forms.BindingContainerValidationForm" className="oracle.adf.controller.struts.forms.BindingContainerValidationFormConfig"/>
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
<set-property property="pathnames" value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml"/>
</plug-in>
In the validation.xml:
<!DOCTYPE form-validation
PUBLIC "-//Apache Software Foundation//
DTD Commons Validator Rules
Configuration 1.0//EN"
"http://jakarta.apache.org/
commons/dtds/validator_1_0.dtd">
<form-validations>
<formset>
<form name="surveyDataForm">
<field property="EmpName" depends="required">
<arg0 key="survey.name"/>
</field>
<field property="DateOfService" depends="required">
<arg0 key="survey.service.date"/>
</field>
<field property="ReloContractor" depends="required">
<arg0 key="survey.relo.contract"/>
</field>
</form>
</formset>
</form-validations>
And in my JSP, I have:
<script type="text/javascript">
<html:javascript formName="surveyDataForm"/>
</script>
<html:form action="/survey.do" onsubmit="return validateSurveyDataForm(this)">
(The validation-rules.xml was copied from the JDev install jakarta-struts folder).
I can now see the Javascript showing up in my JSP page, but I don't have a method generated for validateSurveyDataForm or any form like this. I didn't think I had to create this. Also, even without the Javascript, the validator is not called because the JBO errors for required are still showing up. The only thing I have not done is included the modelReference in the Form Bean definition in the struts-config.xml. I'm not sure this will work, or even what to populate this with, as the UIModel.xml is replaced by PageDef.xml and DataBindings.cpx changes.
Anyone have any ideas?
ShayOnly have one network; wireless. On it's own, the MacBook can use wifi to surf the net and Apple TV can watch movie previews from Apple via wifi.
It did work about two months ago. I haven't used it since then for home sharing but have used the Apple TV on its own.
I read the Troubleshooting page on Apple Support. It involves turning various things on and off, which I did -
Problem with struts validator on WLS 8.1
I am having a strange problem, when I run my app in eclipse using weblogic plugin it works fine and I get no exception. As soon as I run it externally in a standalone server I get an ServletException which seem be be because of struts validator classes. I have checked the classpath and it seems to be identical in eclipse and startweblogic.cmd
By the way, this code works fine on WLS 6.0
Root cause of ServletException.

Any pointer to fix this situation will be greatly appreciated.
-SankateGot the solution.
It was an classloader issue and I fixed by modifying the way EAR was getting packaged.
I was including all commons-validation.jar and other commons jars in WEB-INF/lib dir. Some how it worked on WLS 6.0 but was not able to load the jars in WLS 8.1
Move the jars out of lib dir and copy them to app/lib dir and add them to ejb manifest file because ejb jar is loaded before WAR by the classloader. This way when WAR is loaded, all the required jars are already loaded.
I was getting servletexception and was not able to get to the root of exception (i.e. its a NullPointerexception or NoClassDefFoundException etc) so I added a scriplet in the root jsp and caught Throwable, that was I came to know the root of the problem.

Struts validation not working properly
Hi,
I'm using the struts validator to validate my form.. I've followed all the steps required.. I've checked it quite a few times :)
Currently I want to verify if my form fields have any value, so am verifying the required property.. but when I submit an empty form, it doesn't show an error.. but the log shows the following;
Any suggestions what could be missing?

at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684)I had a similar problem upgrading from struts 1.1 to 1.2.7. The method signatures in FieldChecks changed to include a Validator object:
1.1
validateRequired(java.lang.Object bean, org.apache.commons.validator.ValidatorAction va, org.apache.commons.validator.Field field, ActionErrors errors, javax.servlet.http.HttpServletRequest request)
1.2.7
validateRequired(java.lang.Object bean, org.apache.commons.validator.ValidatorAction va, org.apache.commons.validator.Field field, ActionMessages errors, org.apache.commons.validator.Validator validator, javax.servlet.http.HttpServletRequest request)
After I added org.apache.commons.validator.Validator to the methodParams attribute of validator in validator-rules.xml I no longer got the error (which was a NoSuchMethodException... I had to look at the ValidatorAction code to find that out, for some reason it wasn't in the stack trace). -
As far as I can tell I can't see anything wrong with my validation on struts, but if I put nothing into a required field it doesn't report an error. Any ideas? Below is the offending code:
First Validation.xml
<form-validation>
<formset>
<form name="User">
<field property="email"
depends="required,email">
<arg0 key="user.email"/>
</field>
</form>
</formset>
</form-validation>Next my struts-config.xml:
<form-bean name="User" type="org.apache.struts.validator.DynaValidatorForm">
<form-property name="userName" type="java.lang.String"/>
<form-property name="password" type="java.lang.String"/>
<form-property name="firstName" type="java.lang.String"/>
<form-property name="lastName" type="java.lang.String"/>
<form-property name="email" type="java.lang.String"/>
</form-bean>next the jsp code:
<html:form action="/profile?action=save">
<html:errors/><BR><BR>
<tr>
<td align="left" valign="top"><font face="Arial, Helvetica" size="2">Email:</font></td>
<td></td>
<td align="left"><html:text property="email" size="35" maxlength="255" /><br><font size="1"><i>(Your name @ your company web site address)</i></font></td>
</tr>
</form>And my Action code:
else if (action.equals("save")){
errors = form.validate(mapping, request);
if ((errors == null) || (errors.isEmpty())){
//Save Item goes here
return (mapping.findForward("Profile"));
else {
saveErrors(request, errors);
return (mapping.findForward("show"));
}And my validator-rules.xml (it is the default one that comes with struts, but I included it just in case)

Next my struts-config.xml:That's all? What about an <action-mappings> section
which specifies the action URIs and whether or not
validation is turned on for specific ones?Whoops, sorry I forgot to put my action, although you just made me figure out the answer. I forgot I have 2 versions of the bean, one called Profile and one Called User, and I was trying to test the validation on the Profile bean while I was specifying the User bean :) -
Inconsistent Form Behavior on Failed Struts Validation
So I'm working on a strange bug regarding an Edit User form for an application, where some fields revert to their default and some fields do not.
We have a form for editing users in our system, with most of the usual information inputted in text boxes (login, first name, last name, password, password confirmation). We also have three possible levels of 'admin' - none, admin, and superadmin. These are chosen via radio buttons. There are also a couple of checkboxes (like 'user is active'). Overall, it's a fairly simple form.
When the form is submitted, we do struts validation. We've set up the validation via comment annotation in our Java code, like so:
* @struts.validator type="minlength"
* arg1value="${var:minlength}"
* @struts.validator-var name="minlength" value="8"
* @struts.validator type="maxlength"
* arg2value="${var:maxlength}"
* @struts.validator-var name="maxlength" value="50"
public void setPassword1(String string) {
password1 = string;
}All of the fields in our form are set from user properties, so they're initialized by the values in the user object. For example, if we had user John Smith, an admin, with login 'jsmith,' we'd have the first name and last name fields initialized to John and Smith, and the radio buttons for Admin set to 'admin.' For reference, here's the EditUser.jsp code for the radio buttons, based off of the selectedAdminRole property:
<div class="InputElement">
<label for="selectedAdminRole"><bean:message key="userForm.adminType"/></label>
<html:radio styleId="selectedAdminRole" property="selectedAdminRole" value="None"
disabled="${userForm.loggedInUser.admin and userForm.userId == userForm.loggedInUser.id}">None</html:radio>
<html:radio property="selectedAdminRole" value="Admin"
disabled="${userForm.loggedInUser.admin and userForm.userId == userForm.loggedInUser.id}">Admin</html:radio>
<c:if test="${userForm.loggedInUser.superAdmin}">
<html:radio property="selectedAdminRole" value="SuperAdmin">Super</html:radio>
</c:if>
</div>As you can see above, the struts validator requires passwords to be at least 8 characters long. So if the user tries to change their password to something with less than that, they'll fail validation and they'll end up back on the form with the validation errors in red at the top of the page. However, the form data that they've edited will be preserved. So if John had tried to change his first name to 'Fred,' he'd still see 'Fred' in the First Name text field, even though it wouldn't actually get saved to the user object until he submitted the form with no errors. This works with radio buttons too - if John had tried to set his admin status down to 'none' from 'admin,' the radio button 'none' would still be checked. Basically, it preserves all your progress on the form until you navigate away.
Unfortunately, it does NOT do this when you create a new user. Creating a new user uses the same form, and since there's no user object to get the fields from, they all get initialized to blank - except for one of the checkboxes ('user is active') and the radio buttons for admin (starts with 'none' checked). Now, if the user fills out the form and hits submit, but fails the struts validation, it preserves all the form data in the text fields, but reverts the checkboxes and the radio buttons to their default state.
This leads to the following problem: say I'm trying to create a new admin, Jane Smith. I fill out the whole form, check the 'admin' button, and then enter a four-letter password. I submit, and the form fails struts validation and throws me back to the page with an error message informing me that passwords need to be at least 8 characters. I look over the form again - the login field is still 'janesmith,' the first name field is still 'Jane,' the last name field is still 'Smith,' everything looks fine except I screwed up the password. I enter an 8 letter password and resubmit. Jane then logs in and complains that she's not an admin, because I didn't notice that the 'admin' button had reset itself to the default of 'none' when I failed validation.
My question is, why does it reset the radio buttons and checkboxes - but not the text fields - on failed validation when a new user is being created, but resets nothing at all when an existing user is being edited? I'd like it to reset none of the information when a new user is being created, but I cannot figure out the reason for this inconsistent behavior.
If anyone can help me figure out how to get this working so that nothing gets reset - or at least explain to me the reason for this inconsistent behavior - I would be very grateful. I will also try to provide any additional information I can if this isn't enough.So what you are saying is that radio and checkboxes don't retain their state when validation fails?
Checkboxes are always troublesome because of their design. If not selected, they don't submit any value - so you have to specifically unset them.
My first instinct would be to look at the formbean which you are populating from, and see what (if anything) modifies its values.
- for originally loading the new user page is it an action or JSP? Does it apply any default values to the form?
- check the "input" page you redirect to when validation fails. Is it an action or a JSP?
- is the same form being uses on the newUser jsp and whatever action you are submitting it to?
- is there a form reset() method?
My theory is that the "input" page you are redirecting to when validation fails is an action, and it sets some values on the form prior to loading.
But thats just a guess at this point. Its hard to debug this without a working example. Its been a while since I worked with struts, and never with annotations providing the validation.
Suggestion for debugging: dump the contents of the form bean at strategic points in the process to see that the values are what you think they should be.
- running the save action
- just after validation
- on the jsp page.
Hope this helps some,

Can I use Struts Validator Plugin's html:javascript tag?
Hi:
Is it possible to incorporate the client-side validation using Struts Validator
Plugin's tag <html:javascript>?
i.e.
1) Insert the following tag to A.jsp and define a taglib:
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<html:javascript formName="aForm" staticJavascript="true"/>
2) Define validation.xml as follows:
<form-validation>
<formset>
<form name="aForm">
<field property="aField"
depends="required">
<msg name="required" key="FieldMissingError"/>
</field>
</form>
</formset>
</form-validation>
3) Insert the onSubmit event in aForm:
<netui:form action="SubmitAForm" style="border-width:1px;" onSubmit="validateAForm(this)">Instead of writing something like this -
<p class="logos">Logo1<a href="...></a></p>
<p class="logos">Logo2<a href="...></a></p>
<p class="logos">Logo3<a href="...></a></p>
<p class="logos">Logo4<a href="...></a></p>
<p class="logos">Logo5<a href="...></a></p>
<p class="logos">Logo6<a href="...></a></p>
Why not have something like this -
<div id="logodiv">
<p>Logo1<a href="...></a></p>
<p>Logo2<a href="...></a></p>
<p>Logo3<a href="...></a></p>
<p>Logo4<a href="...></a></p>
<p>Logo5<a href="...></a></p>
<p>Logo6<a href="...></a></p>
</div>
with CSS like this -
#logodiv p { ... } -

File validator-rules.xml
The validator-rules.xml file is default validator-rules.xml file.
Iam using the two java file for ActionForm and Action
ActionForm file
package struts1;
import org.apache.struts.validator.ValidatorForm;
public class bean1 extends ValidatorForm
private String username=null;
private String password=null;
private int number=0;
public void setUsername(String username)
this.username=username;
public String getUsername()
return username;
public void setPassword(String password)

this.number=number;
public int getNumber()
return number;
Action class:
package struts1;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.apache.struts.action.Action;

uname=form.getUsername();
pword=form.getPassword();
num=form.getNumber();
session.setAttribute("uname",uname);
session.setAttribute("word",pword);
session.setAttribute("num",""+num);
catch(Exception e)
return mapping.findForward(target);
In two.jsp file Iam just getting the session value and displaying the result.
The Action and ActionForm are used inside the struts1 file which is placed inside the classes folder.
The Two file is also compiled successful.
When executing the one.jsp file is displayed but when clicking the submit button it giving the error as servlet action is not available.
So Iam try to change some coding in the Action Class
In the execute method I changed ValidatorForm instead of ActionForm.
but it giving the same error.
The same error is displayed when Iam trying the DynaValidatorForm
instead of struts bean class i.e ActionForm.
If any one knows what is the problem in the program please give some instrutction to correct the error or give some simple example program for practice.

Hi folks,
How would I achieve a polling functionality? One of our applications is setup with the 10gR2 version which comes with BC4J and Struts(Struts was a personal choice). I understand we have an af:poll tag with jsf which helps us to achieve the polling functionality. My query is how would I go about doing the same thing through Struts and BC4j. We don't have JSF, so its kind of tricky.
My actual requirement is as follows:-
I basically need to call an oracle report from java. I do this by having a custom implementation of the rwservlet. The oracle report generates a PDF file locally. Which I then need to store on my Database as a BLOB.
I know how to call the report.
I know where the pdf is located.
I know how to store and retrieve the pdf from the DB through Struts.
My only issues is in instructing my application from the report side to pick up the pdf file when the report is complete. I was thinking in these lines:-
Rather than passing the instruction from the report side,in my struts action class i would set up some polling mechanism(which i don't know how to) that would tell me to look for the report in 2 minutes(which is how long the report takes to be generated), then pick it up and store it onto the DB.
Since i "lose control" of the handle after redirecting to a different servlet for the report call, I don't see another alternative other than polling.
Is there an alternative approach i can adopt to achieve the above functionality?
If not, is it possible to poll through BC4J/Struts (as against ADF/JSF)?
If not, please help :) .
Cheers,
KThere is another danger related to this security hole:
Struts suggests to locate JSPs below the WEB-INF directory to protect them from direct access. A JSP located here cannot be accessed directly but only using the appropriate action.
One common approach implement security in a struts framework is to perform the required checks in actions. A user not logged in might for example been forwarded to the login screen instead of the requested page.
If an Application relies on this fact and assumes that it is not possible to call a JSP located in WEB-INF without using the appropriate actions, this bug here opens another hole:
The "currentPath" Parameter allows a user to call any JSP on your Web-Server! Simply modify the URL to look like this:
navigate.do?amId=...&jboViewObject=...¤tPath=WEB-INF\path\to\any\page.jsp
and you are in!

Hi
i have a question and was looking forward for your help...
during struts validation we use depends="int"
so our purpose is to accept values which are pure integers and remaing should be rejected by validator.....but then if we put some text say "abc" it simply gets converted to 0 and validator accepts it and shows no error
So how can validator classes help us to get around this....that is when ever user inserts something that's not a proper number validator should alarm with an errorI've found a solution that works for me:
1. In the form in each jsp of the multi-page form, add:
<netui:hidden dataSource="{actionForm.page}"/>
2. Add a page="<pageno>" attribute to each field element in the validations xml
file, where validation is performed when <pageno> is <= to the current page number.
3. In each action method add:
form.setPage(<pageno>)
where <pageno> is appropriate to the page that this action will forward to. You
will need to initialise page to 1 in the begin() method.
