How can I instantiate and load a new CachedRowSet object from a non-JDBC so
How can I instantiate and load a new CachedRowSet object from a non-JDBC source?
cheerswebrowset reads whole data;
I would rather need to get data line by line -
Section 10.0 of the javadoc for CachedRowSet has this example.
CachedRowSet crs = new CachedRowSetImpl();
crs.setPageSize(5);
crs.execute(conHandle);
Did they forget to set the command? I assume that is the case. What is not clear is how the connection handle is managed. I think it's safe to assume we close the connection handle. The bigger question is pagination. This makes no sense to me:
To access the next page (chunk of data), an application calls the method nextPage. This method creates a new CachedRowSet object and fills it with the next page of data.I have the saame CachedRowSet object. I assume they mean it repopulates itself?
The data from the first CachedRowSet object will no longer be in memory because it is replaced with the data from the second CachedRowSet object.The data is replaced, NOT the CachedRowSet object, right? Nothing in the example shows the object reference being replaced.
Big question: where is it getting the next page from? That all-important issue is not even discussed. If the CachedRowSet has one page in memory and you call pageNext, WHERE does it get the data? Is it keeping my connection open? If so then I cannot close it, right? Maybe it's keeping the data in a temp file and paging that?
The CachedRowSet documentation is clear as mud. Any clarification would be greatly appreciated.Writing raw Java code with the JDBC API in a JSP file instead of a Java class and having problems with the JDBC API doesn't make it a JSP problem. Get rid of that scriptlet clutter and just put it all nicely in a Java class and test it independently as a Java application using main().
There's a JDBC forum around for problems with the JDBC API. -
Serializing ResultSet using CachedRowSet
Hi all,
I am trying to serialize the retrieved results of a query from one machine to another machine by populating the ResultSet into a CachedRowSet object. According to my understanding CachedRowSet is Serializable an should allow for data serialization over the wire. However, when I try sending the data, I get the following error. I googled the problem online and some people suggested that it is a problem with the version of the OJDBC driver. I have tried ojdbc14 and ojdbc6 for XE 11g but the results are the same. Could anyone give me some suggestion about whether it is possible, and how so?
From my understanding, the Connection should be marked as transient and only the raw data should be transferred. I wonder if Oracle's implementation of CachedRowSet is not supporting serializability or whether I am doing something wrong.
thanks!
Here is the error:

If the below does not answer your question mark it ANSWERED and repost it in the JDBC forum
See CachedRowSet in chap 18 JDBC RowSets in the JDBC Developer's Guide
http://docs.oracle.com/cd/E14072_01/java.112/e10589/jcrowset.htm#i630230
That section includes extensive documentation of this and also includes example serialization code you can adapt.

Hi,
I am Ryan.
In our application, we want to be able to sort a CachedRowSet object. Unfortunately there are no built-in methods to sort a CachedRowSet. At the same time we don't want to rerun the SQL by changing the order by clause, which will be another IO in the DB.
We thought about taking a specific column, creating an array out of it and then use the Arrays.sort method for sorting. Interestingly our requirement is slightly higher. We want to be able to sort more than one column at a given time.
Does anybody know how to accomplish this task? Are there any third part libraries out there to get this done?
Thanks

Deleting a row from a resultSet with nulls
Hello All,
I have stumbled across a bit of a problem when using a cachedRowSet
If I select columns from my database that have null values, and I call deleteRow() I get a
NullPointerException.
at com.sun.rowset.internal.CachedRowSetWriter.deleteOriginalRow
However if I don�t select the null columns in my cachedRowSet. I can delete no worries.
I would of though that the cachedRowSet object could handle nulls but it seems it doesn�t, anyone know any workarounds for this?
NOTE: using JTDS driver would that play a part?If I select columns from my database that have null
values, and I call deleteRow() I get a Does the whole row a null record ?
Please put a sample program so that the problem can be reproduced.

StreamCorruptedException from Stateless Session bean to java class
Hi all,
We have 2 servers, a ColdFusion App server which contains suns jdk 1.4.2 and websphere appserver using Ibm jdk, 1.4.2. On Server 1, we have a standalone java class which does a stateless session bean lookup and requests a service from it. On server 2(websphere), we have a stateless session bean deployed which connects to a database using a jndi lookup, executes a query and returns back a CachedRowSet object (which populates the ResultSet from the above query.) In some cases, session bean returns back an array of objects or String objects or just plain int values.
When the java class on server 1 invokes the methods returning CachedRowSet, we are getting a StreamCorruptedException, whereas on the server side, there is no exception. everything gets executed fine on websphere. This is the case only for CachedRowSet and not for other return types(as mentioned earlier the session bean returns an array of object in some cases which the java class on server 1 is successfully able to use).
This is what the piece of code look like on server 1:
// First gets a StatelessSessionBean using suns InitialContextFactory
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
env.put(Context.PROVIDER_URL,"iiop://localhost:2809");
System.out.println("Creating initial context");
Context ctx = new InitialContext(env);
System.out.println("Initial context created.");
Object homeObj = ctx.lookup("cell/nodes/localhost/servers/server1/ejb/SSBHome");
SSBHome eHome = (SSBHome)PortableRemoteObject.narrow(homeObj,SSBHome.class);
System.out.println("Got Home");
SSB eBean = eHome.create();
CachedRowSet crs = eBean.getAccts(param1, param2);
//This is the line of code which throws the exception.
The stacktrace shoows as follows:
Got Home

Again, everything seems to work fine on websphere server.
Any Clue of why this is happening?
All suggestions are greatly appreciated.

The solution mentioned above is not the right solution.
The above given code works fine irrespective of having corbaloc in the url, if you are working in the IBMs jvm.
It fails if you are working in suns jvm.
Anyone with any idea whats missing here.
Thanks a lot for any suggestion/ideas

Dataprovider: javax.faces.el.PropertyNotFoundException
Hi!!!
When I link a textField with a dataprovider field, it works well. OK. After I close the IDE, studio creator, and open again the IDE. When the IDE shows me the textField it tells me this:
javax.faces.el.PropertyNotFoundException: javax.faces.el.PropertyNotFoundException: Field 'APELLIDO1' not found in DataProvider.
I don't understand why it gives me that error. I go to link again the textField, and I can't see the dataprovider fields.
Why???
ByeeeeHi!!!
This problem is like a bug.
When I reopen the IDE, I can see that the cachedRowset property of the Dataproviders is empty. So the textField give me a error. But if I open the SessionBean, where are the Datarpovider and cachedRowset declared, the cachedRowset property becames in a valid cachedRowset object and the textField error disappear, and the project runs well.
What can I do to resolve this problem???
Thanksssss -
I have the following JSP for CachedRowSet :
It works okey for the first time but when I click on next it is giving me : The environment is WebSphere 3.5 on AS400
Note: A servlet gathers the regular resultset , populates the CachedRowSet with it and then puts the CachedRowset in to the session and sendRedirects the request to this jsp...
Any ideas greatly appriciated...
Thanks

END OF JSP CODEI think the problem lies in how you use <jsp:useBean>.
On first entry to this page, I assume that the CachedRowSet has been populated and stored as a session attribute with key "crsItemResults".
For this first time through, the session context will not contain an attribute "crsItems" and so the <jsp:useBean name= "crsItems"....> will do the following:
1. Instantiate a CachedRowSet object with default constructor, define a local variable "crsItems" and assign it as the reference to the new CachedRowSet.
2. Add a session attribute with key "crsItems" and value = the new (and empty) CachedRowSet instance.
3. Perform the initialization code inside the <jsp:useBean> tag.
crsItems = (CachedRowSet) session.getAttribute("crsItemResults");
Retrieves the pre-populated CachedRowSet from the session context and assigns the reference to local variable crsItems.
session.removeAttribute("crsItemResults");
Remove the original session attribute.
At the end of this code, the local variable "crsItems" refers to the populated CachedRowSet but the session attribute "crsItems" refers to an empty CachedRowSet.
On the second time through, the "crsItems" session attribute is retrieved and local variable "crsItems" references the empty CachedRowSet. The original data is no longer available which results in your error.
It's a long-winded theory but I hope it helps. Fixing the problem should be easy - either save the original CachedRowSet with session attribute key "crsItems" and remove the init code or add a line in the init code to re-save the "crsItems" attribute. -
Returning the result of a database query to a client
glassfish
JAX-WS 2.0
NetBeans 5.5
Is it possible to send a CachedRowSet object to a client?
I get an error when i try to do so. (I can't deploy the web service method that returns the CachedRowSet)
Is there a better way to return the result of database query to a client?
I'd appreciate any suggestions or sample code.Hi!
The result of this query will be the max ID of users' IDs.
Let say we have:
String sql="select max(users.id) from users";
Statement st = ctx.conn.createStatement();
ResultSet rs = st.executeQuery(sql);
rs.next();
So you can get the max Id in the following way:
int maxId=rs.getInt("id");

Obtaining CachedRowSet from web service in Axis
Hi,
I could not find any method to pass a CachedRowSet query result from server side of the web service to the client. I want the transleted type also be a resultset.
Does anyone know the basic solution?
I am using Axis and Tomcat as server.Write a method that puts that values into an array and send that. If you look at the Axis Users Guide (http://ws.apache.org/axis/java/user-guide.html) the advice is 'The most reliable way to send aggregate objects is to use arrays".

Get database result as a type of complex object
Hi,
I would like to make a query and send the results with web service to the client by a user defined object type. I send the servis and client code below. My query works fine but I got all array elements of my object equal to null. I could not understand the reason.
Could you look and help me to solve it please?
Server Code:

// create CachedRowSet and output data to object data
try
crs = new CachedRowSetImpl();
crs = iface.getRowSet();
if(crs != null)
while (crs.next())
counter++;
int j = 1;
int i = 0;

Thank You!!!I really wonder, how ur code got compiled ...
Try removing this four lines from ur clinet side code:
String ad[]=new String[10];
String soyad[]=new String[10];
String eposta[]=new String[10];
String card[]=new String[10];Now
your all get methods return String...but u are assigning that string to
array of strings like :
ad = obje_return.getisim(i);
soyad = obje_return.getsoyisim(i);
eposta = obje_return.getemail(i);
card = obje_return.getkart(i);instead write it like this:
String ad = obje_return.getisim(i);
String soyad = obje_return.getsoyisim(i);
String eposta = obje_return.getemail(i);
String card = obje_return.getkart(i);If above thing doesnt work ....
I am very sure problem is not with webservice..its between jumbling of string/int and arrays of respective...
because when u define new array of objects(in ur case: array of Strings), all newborn strings are initlialized to null. -
Reading a modified data column in a cachedrowset
I am using the tutorial
http://developers.sun.com/jscreator/learning/tutorials/2/inserts_updates_deletes.html
as a base of learning.
I want to detect the edited changes to any row/column data in a cachedrowset displayed in a table.
I have put all the fields of the table in a virtual form and set the "submitonchange" attribute of each element.
When my server function "textField1_processValueChange()" is executed the value that I get from the element via the code ...
CachedRowSetDataProvider cdp = tripDataProvider;
try {
RowKey rk = cdp.getCursorRow();
FieldKey fk = cdp.getFieldKey("DEPDATE");
Date d1 = (Date)cdp.getValue(fk);
is the original value of the field, not the new value.
What do I have to do to get the edited value?
thanks
jim murrayThe processValueChange method passes a ValueChangeEvent object as a parameter.
Try using ValueChangeEvent's getNewValue method to get the edited value. The return value is an Object so you'd have to cast it to the appropriate object type.
NOTE: I have not tried this, so I don't know if it will work. -
Tag Library to display CachedRowSet contents?
i am not a strong proponent of OR mapping. I think relational data should be treated as just data. Too much hard work to map data to objects.
Is there a tag library that I can use to iterate through the contents of a CachedRowSet?
I want to be able to iterate through it using a tag such as
<c:forEach var="row" items="${rowset.rows}">
<tr>
<c:forEach var="column" items="${row}">
<td><c:out value="${column.value}"/></td>
</c:forEach>
</tr>
