Problem with JSF: strange exception !
Hello friends :)
i have a web application with JSF1.2 with the next libraries:
- jsf-api-1.2_07.jar (SUN-RI)
- jsf-impl-1.2_07.jar (SUN-RI)
- jsf-facelets-1.1.14.jar
- tomahawk-1.1.6 (apache.myfaces)
I have in my application a custom tag that was developed based on tomahawk-1.1.6 library. This tag displayes
a form that is obtained by web services.
So, when i run the application, i have a index.jsp that redirect to form.jspx (here is the tag) and i can see the form well and in this point it is right, the custom tag works ok. But when i push a bottom to refresh or save the form, and the request arrives to server, it response me with the following exception: (not reach the controller)

I dont understand why this happening. It seems as if the server dont understand the format data request.
I think the custom tag is ok and it is not the problem. Maybe the problem is configuration, but i dont know.
Thank you so much for you help!
This component or custom tag has worked well in others similar projects (somebody told me that).
But, where does it define the component state? what do i need to define it?
It is de custom tag:
*<viaform:formulario clienteHandler="#{formularioPageBean.formularioHandler}"*
* action="#{formularioPageBean.actionFormularioEnd}"*
* actionListener="#{formularioPageBean.actionFormularioRefresh}" />*
Thank you very much

Very big problem with JSF about FORM and "id=" for HTML form's elements and
I have discovered a very big problem with JSF about FORM and "id=" for HTML form's elements and java instruction "request.getParameterNames()".
Suppose you have something like this, to render some datas form a Java Beans :
<h:dataTable value="#{TablesDb2Bean.myDataDb2ListSelection}" var="current" border="2" width="50%" cellpadding="2" cellspacing="2" style="text-align: center">
<h:column>
<f:facet name="header">
<h:outputText value="Name"/>
</f:facet>
<h:outputText id="nameTableDb2" value="#{current.db2_name_table}"/>
</h:column>
</h:dataTable>
Everything works fine...
Suppose you want to get the name/value pairs for id="nameTableDb2" and #{current.db2_name_table} to process them in a servlet. Here is the HTML generated :
<td><span <span class="attribute-name">id=<span class="attribute-value">"j_id_jsp_1715189495_22:0:nameTableDb2">my-table-db2-xxxxx</span></td>
You think you can use the java instructions :
Enumeration NamesParam = request.getParameterNames();
while (NomsParam.hasMoreElements()) {
String NameParam = (String) NamesParam.nextElement();
out.println("<h4>"++NameParam+ "+</h4>);
YOU ARE WRONG : request.getParameterNames() wants the syntax *name="nameTableDb2" but JSF must use id="nameTableDb2" for "<h:outputText"... So, you can't process datas in a FORM generated with JSF in a Servlet ! Perhaps I have made an error, but really, I wonder which ?

Edited by: ungars on Jul 18, 2010 12:45 AMWhile I certainly appreciate ejb's helpful responses, this thread shows up a difference in perspective between how I read the forum and how others do. Author ejb is correct in advising you to stay inside JSF for form processing if form processing is what you want to do.
However, I detect another aspect to this post which reminds me of something Marc Andreesen once said when he was trying to get Netscape off the ground: "there's no such thing as bad HTML."
In this case, I interpret ungar's request as a new feature request. Can I phrase it like this?
"Wouldn't it be nice if I could render my nice form with JSF but, in certain cases, when I REALLY know what I'm doing" just post out to a separate servlet? I know that in this case I'll be missing out on all the nice validation, conversion, l10n, i18n, ajax, portlet and other features provided by JSF".
If this is the case, because it really misses the point of JSF, we don't allow it, but we do have an issue filed for it
https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=127
If you can't wait for it to be fixed, you could decorate the FormRenderer to fix what you want.
I have an example in my JSF book that shows how to do this decoration. http://bit.ly/edburnsjsf2

Problems with JSF and included subviews
Hi everybody,
I' ve got a problem with JSF and included subviews which makes me going
crazy. I've got no clue why my web-pages are represent wrongly. The only
tip I've got is that it must be connected with the kind I do include my JSF-pages.
When I use <%@file="sub.jsp"%> my pages are are represent right. When I use <jsp:include page="Sub.jsp" /> or <c:import url="Sub.jsp" /> ( mark: the usage of flush="true" or flush="false" doesn't matter )
my pages are represent wrongly.
The usage of tags like f:facet or f:verbatim were also included but didn't point to an solution.
I searched the whole Sun Developer Forum and some other web-sites for any solution for my problem but the given hints and clues didn't help. Now I'm trying to post my problem directly in Sun's Forum in hope to get help.
My environment is the following:

benjaminHello Zhong Li,
many thanks for your post, but it didn't work.
My problem is that the JSF-Components im my included or imported
JSP-Pages does not accept any kind of style or styleClass for
designing. The components take over the informations for colors
but not for alignment.
When I take a look at the generated JAVA-Source in $TOMCAT/WORK/WEBAPP for my sub.jsp ( sub.java )
it seems that the resulting HTML-page would be presented correctly.
But later when I start the application via Firefox or Mozilla the html-sourcecode is totally wrong.
In my example I create a simple grid with 2 rows and 2 columns.
Both columns contains JSF-Outtext-Components and are included with div-tags.
The generated Sub.java shows that the text would be setted in the div-tags. Unfortunately the html-sourcecode represented by my browser shows that jsf-text is not setted in the tags but in the <h:form> tags. The div-tags are neither rounded by <h:form> nor containing the JSF-OutText-Components.
Any clue?
Many thanks Benjamin

Tunneling and problem with unknown host exception
hello! i've got a problem with https. i use jdk 1.5.0, jboss-4.0.4.ga-patch1, soap.
and i'm going crasy.. i've testet my client code at our network and it works fine. but if i want to get jobs from the server of our customer, my client throw an "unknown host exception: firm".
i wonder why it hasn't the full host. the url may look like this: https://firm.sub.com:443/ and while the client connects to the server, i depugged it and the host is correct: firm.sub.
but after the connection, when the client want to get something from the server (when it wants to communicate with the server over soap) it crashs.
my client code looks like this:
private ClientInterfaceEndpoint getClientInterface() throws ServiceException {
QName serviceQName = new QName(DOCSERVER_NAMESPACE, CLIENT_INTERFACE_SERVICENAME);
URL wsdlUrl = getClientInterfaceWsdlUrl();
log.info("*******WSDLURL host: " + wsdlUrl.getHost()); // out: firm.sub

System.setProperties(properties);
return url;
}if it's usefull: the customer use a apache server (not tomcat) where a the server is and the client at another system the jboss.
The customer told me: if i want to connect the client via http i have to tunnel.. maybe i have to tunnel using https too?
have i to generate the endpoint classes a second time, extra for https?
or doesn't soap like host like "firm.sub"?
can anyone help me please?!
sorry, my english isn't very well...sorry, it's not the same error. The output is: Unable to connect to any host due to exception: java.net.socket.exception: java.net.socket.exception: Unregcognized windows socket error: 10106: create.

I am having problem with myfaces tomhawk components in a portal environment
They work fine as a standalone web application
When we make it a portlet, they render properly, but the pagination and links in the calendar components are not working
They submit the page to the server, but does nothingHi,
WLP 9.2 will be using the Sun RI for JSF portlets. We are going to certify with Apache MyFaces post GA.
The Beta drop of WLP 9.2 is coming soon and you will be able to do more around development.
We appreciate you taking the time to review the product and provide feedback.

Hello,
I have a problem with finishing my project which is based on JSF, Hibernate and EJB technologies. The matter is that I�ve built the application which manages a group of reports and assign sections and reports to the single user. I have two types of users, simple users and administrators. Simple user log in to the system and is able to generate reports which were assigned to him by admin. In the system can be more than just a one administrator. The problem is when one administrator is on-line and another log in to the system. Then both of them are working on the same instances of classes. In JSF files I�m working on created session beans which are defined in faces-config file. I�m new in JSF so maybe my attitude to this technology is not correct. If anyone know how to solve my problem please help me �
Regards

The same instance of LoginBean.class is used by both of administrators and this is the problem ...The above statement is wrong. There are two different sessions for the two users. You are probably seeing data because its persisted in the database by one user and when the next user logs in, the application fetches data from the DB and displays it. Its more of a design problem if you do not want the second user to see the data which the first user has entered.Akash,
I think we do not understand each other. My application is really simple. Simple user is able to see some links to reports when log in to the system or not. It depends on administrator which is able, in the form I've mentioned before, to assign the right to see a report by a user or not. I don't know what do you mean by saying "There are two different sessions for the two users".
To explain you what the problem is try to follow such a situation. Let say we have two classes : LoginBean.class and EditForm.class. Based on that classes we create two session beans : loginBean and editForm in faces-config file as follows:
<managed-bean>
<managed-bean-name>
loginBean</managed-bean-name>
<managed-bean-class>
log.LoginBean</managed-bean-class>
<managed-bean-scope>
session</managed-bean-scope>
</managed-bean>
<managed-bean>
<managed-bean-name>
editForm</managed-bean-name>
<managed-bean-class>
log.EditForm</managed-bean-class>
<managed-bean-scope>
session</managed-bean-scope>
</managed-bean> We have also created two JSF files, one login.jsf which include authorization component based on loginBean and second: editForm.jsf which include a SelectOneMenu component to choose a user and a form to assign selected user a report based on editForm bean.
We log in to the system as a administration. We are after authorization and enter the editForm.jsf file. We choose a user from SelectOneMenu component and make some changes in the form. But we do not submit anything and do NOT send it to the database. In this moment another administrator log-in, go to the editForm.jsf file and after that he sees that in his selectOneMenu component a user is chosen and the form is filled with data entered by prevoius administrator.
I'm new in JSF but I've thought that when I create a session bean a new instance of bean ( new instance of class ) is created for all users which try to use it, or maybe I'm doing something wrong or should write some additional code to achieve such a function ... -

Reflection problems with null pointer exception
I am having a problem with reflection. I keep getting a NullPointerException and can't figure out why.
It is happening when I call this:
ResponseObject result = (ResponseObject)method.invoke(classInstance, argArray);
I can't figure out what the problem is. I had this reflection working, and then I made some changes to how the argument array was created. In the end, the argarray is the same.
Any ideas?Also, the API for the method class says that a
NullPointerException is thrown if the object in the
first argument is null. I have tested for this, and
it is not null.does it? read again, because giving 'null' as the first argument is perfectly legal. how else would you reflectively invoke a static method, since you might not have an actual instance of the class to pass -
CPU utilization problem with JSF
Hi,
I am using MyFaces 1.1.4 and tomahawk 1.1.3.
I am using EJB 2.0 and weblogic server 9.2
I have a problem with the performance of my application. The response time for 500 concurrent users is arnd 10sec. However, the CPU utilization normally hits *95-97%.*
I have disabled all the logging to reduce the file IO. Also, all the code has been optimised. Still the problem exists. Now, I cannot think of any way to overcome this. My project is getting delayed because of this.
Request you all to pls help.
Regards,
Milan.What type of server or servers are you using. I am assuming which I hate to do is that your EJB's are for CRUD and you a connection pool. Have tried to optimize the DB connection pool's ?.

Problem with JSF AJAX portlets
I am seeing the following issues with JSF portlets
1) When you AJAX enable the portlet, they will not work. There are some javascript errors on the component we are using. They work fine if we don't AJAX enable them
2) I had 2 portlets. 1 JSF and 1 pageflow portlet. If I click on a link in pageflow portlet and after the page gets refreshed, nothing will work in JSF potlet. Again javacript errors
If we had only 1 portlet on the page, JSF portlet works fine
Do you think the prototype javacript library used in the portal causing any issues?I tried with <naming:namingContainer> immediatly after the f:view tag , but still getting same errors
I am psoting the generated html and javascript error

Problem with JSF 1.2 and Tomcat 6
Hello guys,
I have here:
Tomcat 6.0.10
JSF 1.2_04_b10_p01
I followed these steps without success:
http://forum.java.sun.com/thread.jspa?threadID=787962
http://forum.java.sun.com/thread.jspa?threadID=5156242
Here what I did:
1) Removed the following line in $TOMCAT_HOME/conf/server.xml
<Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />2) Add the following lines to $TOMCAT_HOME/conf/web.xml
<context-param>
<param-name>com.sun.faces.expressionFactory</param-name>
<param-value>org.apache.el.ExpressionFactoryImpl</param-value>
</context-param>3) Add the following libs to $TOMCAT_HOME/lib
jsf-api.jar
jsf-impl.jar
jstl-1.2.jar
4) Add the following lines to $MYAPP/WEB-INF/web.xml
<listener>
<listener-class>
com.sun.faces.config.ConfigureListener
</listener-class>
</listener>
<listener>
<listener-class>
com.sun.faces.application.WebappLifecycleListener
</listener-class>
</listener>And here is "the final product":

Thank you.Thank you for the answer rlubke,
Well this happened because I had compiled the project with the jstl-1.1
The workaround to make jsf 1.2 run on tomcat 6 really works.
But now I have a problem because the JNDI tree in tomcat is read-only ( ro )
and I need to bind a object in the JNDI so an exception happens:
WARNING: Ocorreu um erro inexperado:
javax.naming.NamingException: Context is read only
at org.apache.naming.NamingContext.checkWritable(NamingContext.java:903)
at org.apache.naming.NamingContext.bind(NamingContext.java:831)

at org.apache.naming.SelectorContext.bind(SelectorContext.java:171)
at javax.naming.InitialContext.bind(InitialContext.java:400)Here is the code:
try{
Context newContext = new InitialContext();
newContext.bind( dataSourceWrappedID, wrappedDs );
newContext.close();
}catch(NameAlreadyBoundException nabe){
// ok no problem..
}catch(NamingException ne){
if ( log.isWarnEnabled() ){
log.warn("Ocorreu um erro inexperado:", ne);
}You know how to make the JNDI tree in tomcat read-write ?
Thank you a ton. :-) -
