How i can solved this trouble?
Thanks.

one question... Is just redploying ¿? If you restart Glashfish it persist the problem??
Look at this: EclipseLink + JPA Guice Persist and Redeployments ....
And this: https://bugs.eclipse.org/bugs/show_bug.cgi?id=326552

Seems you have two different JARs containing same classes within the classpath

It looks to me like you are using Hibernate 3.x. If this is the case, I would make sure you are on version 3.6.10+ of Hibernate core. Older versions may not have the necessary class definition that the spring framework is looking for. The following link shows Hibernate 3.6.10 has the class definition you are missing: http://tool.oschina.net/uploads/apidocs/hibernate-3.6.10/org/hibernate/QueryTimeoutException.html

I've got the same error when saving de object. Well It's weird but apparently hibernate doesn't understand 0 (zero) as a value for #Id columns. I was trying to save a referenced object and its #Id value was 0. So I changed the id value to 1 and it worked =S

To hide/unhide a button in the first row of a table

I have a table that is created using an old JSF component library called Woodstock. I want to show a button just in the first row.
.jsf file:
<webuijsf:form id="reportlist">
<webuijsf:table id="table4" title="#{msg.reports_table_header}">
<webuijsf:tableRowGroup selected="#{user$recentreports.selectedState}" binding="#{user$recentreports.tableRowGroup}" id="tableRowGroup4"rows="15" sourceData="#{user$recentreports.reportList}" sourceVar="currentRow">
<webuijsf:tableColumn id="column12" binding="#{user$recentreports.column12}" onClick="setTimeout('initAllRows()', 0)" selectId="#{user$recentreports.selectedCheckBox}">
<webuijsf:checkbox id="selectedCheckBox" binding="#{user$recentreports.selectedCheckBox}" />
<webuijsf:button binding="#{user$recentreports.deleteSelectedButton}" actionExpression="#{user$recentreports.deleteButton2_action}" id="deleteSelectedButton" text="#{msg.report_delete_selected}"/>
</webuijsf:tableColumn>
.java file:
after some getter/setter methods of the UI elements I have the setter method of the column12:
public void setColumn12(TableColumn column12){
System.out.println("setTableColumn12");//works fine
buttonTest=Integer.parseInt(tableRowGroup.getRowKey().getRowId());//nullpointer exception comes here
System.out.println("buttonTest"+ buttonTest);// this never shows up
this.column12=column12;
}
I want to get the row key and set my button's visible property to false. But I can not, I am getting

exception. What am I doing wrong? What is the right way to do it?

In which line is the error? As this is a NullPointException you are passing null somehwere as argument or trying to invoke a method on null.

JSF app creates record with all null fields in MYSQL db [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.

...
You've a bug in a new Comparator() {} anonymous class somewhere in the findRange() method of the entitybeans.jpa.MovieFacade class. It's attempting to access/invoke something which is null. Something like
Collections.sort(somelist, new Comparator() { // line 61
#Override
public void compare(Object o1, Object o2) {
// ...
something.doSomething(); // line 65, something is null here!
// ...
}
});
To fix this, you need to check if it is not null before accessing/invoking it. Something like:
if (something != null) {
something.doSomething(); // something is guaranteed not null here.
}
That's all which can be answered based on the information given as far.

Any ideas why I am getting this?

Here's the relevant bit
java.lang.NullPointerException
at org.apache.jsp.student_jsp._jspService(student_jsp.java from :65)
(the remnant of your question is actually irrelevant, I was so kind to remove the monster servlet code and all INFO messages from your original question to minimize noise).
This exception and trace indicates that you're using old fashioned scriptlets (those <% %> things) in student.jsp file instead of taglibs and EL (which is null-safe). Your culprit is in line 65 of the compiled class file of the JSP file. You can find this class file in servletcontainer's work folder. You need to trackback this to the code in the JSP file itself. It'll look something like this:
<%= someBean.getSomeProperty(); %>
The NullPointerException indicates that someBean is null. Fix it. The ideal fix would be to avoid scriptlets to all extent. E.g.
${someBean.someProperty}
This will never throw NPE whenever ${someBean} is null.
As per the other stacktrace:
org.hibernate.hql.ast.QuerySyntaxException: student is not mapped [from student]
This means that the entity student is nowhere mapped. This is usually supposed to be the short class name of the entity. Since the normal Java convention dictates that the classnames ought to start with uppercase, I'll bet that it's actually called Student and not student. You need to fix it accordingly in your HQL query.
If that is not the case, then you simply need to add it to your Hibernate mapping.

Invert your string comparisons. Call equals() on the constant value. This will help avoid NullPointerExceptions.
Here is an example:
if ("student".equalsIgnoreCase(view))
If hibernateSession.createQuery() returns null, you will get a NullPointerException

If it does turn out to be one of your string comparisons, then you might like to adopt a safer strategy
if ("student".equalsIgnoreCase(view)) { ... }
else if ("course".equalsIgnoreCase(view)) { ... }
// etc
You get to avoid the null check, and you're protected from NPEs
