Why cannot execute DB operation at client side with dynamic proxy?

I want to execute a DB operation at client side with dynamic proxy. that is bypass EJBs to execute DB operation. And there is a data source in weblogic server, and I get an EJB instance using dynamic proxy, get connection using this instance, then invoke executeQuery method. But it is failed, and throw exception when execute "conn.setAutoCommit(false)" as below:
<Caused by: weblogic.rmi.extensions.RemoteRuntimeException: Unexpected Exception - with nested exception:
[java.rmi.UnmarshalException: Could not unmarshal method ID; nested exception is:
java.rmi.UnmarshalException: Method not found: 'newArrayDataResultSet(Loracle.sql.ARRAY;JILjava.util.Map;)']
at weblogic.jdbc.rmi.internal.ConnectionImpl_weblogic_jdbc_wrapper_PoolConnection_oracle_jdbc_driver_OracleConnection_813_WLStub.setAutoCommit(Unknown Source)
at weblogic.jdbc.rmi.SerialConnection_weblogic_jdbc_rmi_internal_ConnectionImpl_weblogic_jdbc_wrapper_PoolConnection_oracle_jdbc_driver_OracleConnection_813_WLStub.setAutoCommit(Unknown Source)>
but it is no exception and run well using EJB, who can tell me why? if it is a weblogic limitation? and my version of WLS is 8.1 sp3

Hi,
Do you create the connection object on the server and pass it over to the client, we do not allow passing the connection object over the wire.

What kind of hardware is required on client side with OWB 10gR2?

Hi,
What kind of hardware are you using, on client side, with OWb 10gr2?
Currently I'm using a PC having a Pentium 4 1.7Ghz with 1.5 GB Ram but it's extreamly slow.

Hi
For Windows, ensure that the machine has a minimum of 850 MB disk space, 768 MB available memory, and 1GB of page file size, TMP, or swap space.
For Linux, ensure that the machine has a minimum of 1100 MB disk space, 768 MB available memory, and 1GB of page file size, TMP, or swap space.
Are you running an anti-virus? If so, try stopping it and run OWB. This is due to the anti-virus action and OWB being a java based tool...

Merging randomly-named XML data file on client-side with pdf designed in Livecycle 7.0 (and addition

Okay, as a heads up I work for a financial institution and we are converting our legacy "jetforms" to pdf format. I have in my staff for the project, 2 code developers and myself- a form designer. We have currently spent 2 months in trial and error attempting to resolve this problem, please let us know anything you can have. All client-side (internal) machines are running Windows XP and Adobe Reader 7.0.7
The software we use as a financial institution allows our users to export a customer's data file onto their machine which is then renamed to include the member's account number and first and last name for our staff to determine which data file they need more accurately. In legacy jetforms, we have developed a program that pushes the data from the customers file that they select, into the jetform that they want to open and the matching fields in the data file fill in the fields of the jetform. Clean and simple.
Now, i have hit nothing but frustration when attempting to perform the same process with pdfs using a form designed in livecycle designer 7. First, i see no obvious command for opening a pdf and importing a data file using a command line, like pdfmerge or something of the sort in which an xml data file can be specified and a pdf can be specified. I saw something like it using an fdf format and attempted to do this but apparently reader cannot import the data into the pdf that was designed adobe livecycle 7. All i have been seeing is database connections and using javascript inside the form to populate fields based on these database connections, etc. etc. or doing a manual file>import data>etc. which we don't want to have our staff do. We do not have reader extensions enabled, simply because i cannot get an adobe representative to call me and discuss pricing nor see any estimated pricing chart around. I don't know if reader extensions are necessary for this or not but i'm becoming very very frustrated with it.
We don't want a complex server-side data connection binding with dynamic input. No, we just want it where our developers can say "if this data file is selected, and this pdf form is selected run this command" which would be a simple pdfmerge type solution. Is this possible or do i need to stay with jetforms until our software the billion dollar financial institution uses does form building inside its own application? I don't want to fight about who is better, what version to use, etc. I just want the straight up honest truth. If you need to know the pricing that the reader extensions would have to go by, assume there will be 500 client computers that will need to use it.

From your post it sounds like you are Central Pro (a product for which I am by no means an expert), but you say you want to upgrade to a newer product from your "legacy" one. Is there a reason for this? Have your requirements change so that it no longer fits them? Central is still in the current Adobe roster and as far as I know there is no plans to get rid of it any time soon, so if it does everything you want I don't see why you would want to change.
There is no product in the LiveCycle suite that merges xml data into a form from the command line. LiveCycle (with the exception of Designer) is a suite of server products, so the closest you would come is LiveCycle Forms (merge the xml and create a fillable PDF) or LiveCycle Print (merge the xml and print the form).
Hope this helps somewhat.

User form: to execute some operation at server side for a command click

jurajsiska Apr 11, 2006 7:56 AM
I'm creating a customer user form. I want to do some thing at server side when a command is clicked, but don't want to save any modified value until user clicks "Save" button. There is property for command display class, named "command", but it just gives you opportunity to execute some pre-defined command, Save, Recalcuate, or Cance. How can I achieve this by customizing the event handler for command click?

I just figured out a way myself. Create a hidden field in your user form, use the java script to set hidden field to some value for the "onclick" property of BUTTON, and to check this hidden value in the properties command of BUTTON to know if it's coming from click or refres/recalculate. Of course you need to reset the hidden value in the expression of command property.
Hope it's helpful for somebody having the same situation,

How to execute jsp script at client side

i have a web page developed in jsp. i need to capture the client machines ip address and MAC address. i got ip address. how to get MAC address who are all accessing that page

Yeah, there's no javascript that'll do it either. I saw a bunch of posts from php guys trying to do the same thing. It's just not part of TCP/IP. There are apps that will give you the MAC based on an IP in a local network. That's all I've seen available.

Hi,
Does anyone can help me with my applet. It must get the current page and print it in landscape out over at the user side (local printer).
Here some sample of my source to help....
// JavaScript part
function print(){
var myURL = document.location.href;
alert(myURL);
testApplet.print(myURL);
// Applet part
public class MyClass extends Applet implements Pageable, Printable {

Paper sheet = new Paper();
sheet.setImageableArea(0,0,landscape.getImageableWidth()+ (landscape.getImageableX()*2),landscape.getImageableHeight()+(landscape.getImageableY()*2));
landscape.setPaper(sheet);
landscape.setOrientation(PageFormat.LANDSCAPE);
JTextPane txt = new JTextPane();
txt.setPage(myURL);
// this method initialise the parameters for the printing

I have printers define and they worked well. Also, I have use the same code but without the Applet (calliing it from the main and with a static url) and it work perfectly. I'm pretty sure it's the Applet who's causing trouble.
Anyone has any idea or sample to help me?
Thanks

It has to do with the JS call to the print method. I got around it by calling my printData() method in a separate thread...
try something like this:
============================
public void jsPrintData()
if ( isPrinting )
return;
isPrinting = true;
Thread runner = new Thread()
public void run()
printData();
runner.start();

Why cannot iTunes sync movies from iPhoto taken with iPhone

I take little movies with iPhone. (5Mb)
iPhoto copies then to the Mac with the Photos.
Movie plays in iPhoto.
In iTunes I say Sync event and tick include videos on. The movies are not copied back to the iPhone.
Checked in iPhoto, event says 18 items (17 are photos one is the movie MOV04391.MPG)
In iTunes > Photos tab. the event only shows 17 items.
Thanks in anticipation...

Try launching iPhoto while holding Option, to create an alternate iPhoto library that you can test with. You can always switch back to the original iPhoto library launching iPhoto while holding Option again.
If it works in the new test library, you'll probably want to switch back to the main library and then rebuild it by holding down the Command and Option keys when launching iPhoto.
Also, when you email photos from the iPhone you should see an option to email as actual size, along with the compressed options.

Limiting bandwidth on client side with Camera.setQuality() inconsistent?

After successful bandwidthCheck() limiting bandwidth to setQuality(75000, 100)
leads to the desired result of publishing the stream with max bitrate of 75000 byte/s.
On other locations the same setting results in publishing the stream with max bitrate of
approx. 13107 byte/s. If I change bandwidth to setQuality(400000, 100) i am reaching the desired
bandwidth limit of 75000 byte/s.
Stream is published with h264Settings.setProfileLevel(H264Profile.MAIN, H264Level.LEVEL_5_1).
Any clues?
These behaviour only occurs with outStream.videoStreamSettings = h264Settings;
If videoStreamSettings is not set to h264Settings all things are doing well as expected.

ACE30 - PING to VIP and Client side SVI not working

Hi Guys,
Having setup the ACE30 based on the configuration guides, I've been able to get basic load balancing working, probes, stickness etc. However in testing connectivty, I've noticed that from the real server on the backend I cannot seem to PING:
1. The VIP for the web service that the server is a part of
2. The Client side SVI
I'd like this to work to ensure full connectivity.
I've applied ACLs to the Client side SVI (on the ACE) to allow this in both directions, and also removed any ACLs attached to the client side SVI on the MSFC where the subnet is actually homed. However I just cannot seem to PING the Client side SVI on the ACE, or the VIP. Trying to understand if this is normal behavior.
Have inserted my config below for completeness.

To ping your VIP of the webserver, you should apple the service-policy input command on VLAN 186 too. Currently the VIP only listens on VLAN 11. For the SVI i think that was forbidden by security reason, but i cant remember anymore. Maybe you just need to put the management policy on the interface VLAN 186. If it dont work, then my first guess was right

Cannot execute RSA1

Hi everyone,
I have an URGENT issue, cannot execute RSA1.
Already modify WE20 with the missing entry (BWDCLNT700, LS) but in table RSBASIDOC I dont see it.
When I execute RSA1 display the same error and delete from WE20 the new entry.
Please help me to solve this!!!
<b>Entry in inbound table already exists
Message no. E0412
Diagnosis
Inbound parameters already exist in the partner profile under the following key:
/BWDCLNT700/LS//RSSEND////
This relates to the key fields in table EDP21:
SNDPRN Partner number
SNDPRT Partner type
SNDPFC Partner function
MESTYP Message type
MESCOD Message code
MESFCT Message function
TEST Test indicator
Procedure
Please check the EDI partner profile.</b>

Hello All,
HERE THE RELEVENT ANSWER:
I found solution for this error.
1. Go to WE20 and check whether Partner profile T90CLNT090 exist in LS type,if not just add Parnter profile with same and save.
Partner profile Name: T90CLNT090
TYPE: LS
Give:
Ty: US
User: User Name
Lang: EN
and Save.
2. Again re-click on Partner Profile: T90CLNT090
you will see ,there will be some entries in Inbound & out Bound Tabs.
Delete the following from outbound:
1.RSRQST
Delete the following from inbound.
1.RSINFO
2.RSSEND
and save your partner profile.
3. now execute - RSA1, it will ask to active Workbench. Just activate it . it will work now.... Cheers.
Regards,
K.Ramesh
Note: Please give some points ,if it solves your problem.

Webservice without client side interface

Is there a way to call a webservice from the client side with out having any jar or interface used in the client side?
Can you recommend me some good links on this?
Thanks

The most flexible client invocation method is DII (Dynamic Invocation Interface). With this approach your client needs just the standard JAX-RPC JARs from the JWSDP, but it doesn't need any runtime classes generated by WSDL to Java mapping tools.
The following link has some DII examples as well as comparisons with the other types of client invocations:

Chart Control printing at the client side

Hi,
I have multiple chart controls (in VS2010) on an aspx page, which also show their relevant detaild data in a table on the same page. I could not found yet an appropriate solution for printing such a page with chart control and other data.
In fact I was able to print the chart alone at the client side, but only by sending it directly to the printer, this method is unable to show print preview dialog to the client.
Then i started thinking in another direction, and came with the idea to export my desired controls into a pdf file which then can be shown in the browser (which resolves browser independance), for that i used nReco (the dll which comes with dot net) pdf converter
which can convert the whole html page into the pdf file (by passing the url of the page) and then opens/saves in the browser to print.
But when i pass it (to one of the the funtion in nreco) a container means a div or a panel control which holds the chart control and other normal controls then it gives me the error that unable to convert to pdf.
Tis may be due to the relative path of the chart control image.
I am stuck in this situtation, My original requirement is to show the the print preview to the user at client side with all printing options. It would be very convenient if the desired control can be exprted to pdf.
And I don't want to use any ohter third party control (for print preview at client side) which needs to be installed on the client machine.
Thanks.
Code Sample:
using NReco.PdfGenerator;
on Load
Chart1.Series[0].Points.DataBind(datatbl.Rows, "ColHeading", "colName", string.Empty);
On Print
HtmlToPdfConverter nRecohtmltoPdfObj = new HtmlToPdfConverter();
nRecohtmltoPdfObj.Orientation = PageOrientation.Portrait;
StringBuilder sb = new StringBuilder();
StringWriter tw = new StringWriter(sb);
HtmlTextWriter hw = new HtmlTextWriter(tw);
ChartPanel1.RenderControl(hw);
string temp =
"<html><head><style>td,th{line-height:20px;} tr { page-break-inside: avoid }</style><script>function subst() {var vars={};var x=document.location.search.substring(1).split('&');for(var i in x) {var z=x[i].split('=',2);vars[z[0]]
= unescape(z[1]);}" +
"var x=['frompage','topage','page','webpage','section','subsection','subsubsection'];for(var i in x) {var y = document.getElementsByClassName(x[i]);" +
"for(var j=0; j<y.length; ++j) y[j].textContent = vars[x[i]];}}</script></head><body onload=\"subst()\">"
+ sb.ToString()
+ "</body></html>";
nRecohtmltoPdfObj.GeneratePdf(temp);
Please suggest a batter way out.

Is this question hard to answer? or I am going to the wrong direction since I am new about Java EE/EJB.
Can anyone give me some answer?

How to implement a persistent HTTP connection on client side...

Sorry for the inconvenience everyone, but I could really use some help here since I am a total newbie to Java programming
I am trying to implement a persistent HTTP connection on the client side with request pipelining. The way I understand it is that client requests will be sent to the server, which will reply to them back to back, and then the client will read them accordingly. But when I read the server responses, I get only the reply for the first request, and nothing further, when I actually expect it to give me as many responses as the number of requests I ussued. Here is a sample code illustrating what I am trying to do.
====================
import java.io.*;
import java.net.*;
import java.util.*;
public class HttpClient {
public static String host = "www.somehost.com";
public static int port = 80;
public static String pathname = "/download.asp";
public static String protocol = "http";
public static ArrayList list;
public static void main(String[] args) {
Parser parser = new Parser();
list = parser.getIDs();
try {
Socket socket = new Socket(host, port);
InputStream from_server = socket.getInputStream();
PrintWriter to_server = new PrintWriter(socket.getOutputStream());
OutputStream to_file;
to_file = new FileOutputStream("HTTP_response.txt", true);
for(int i = 0; i < 3; i++)
String s = (String)parser.getIDs().get(i);
String filename = "/download.asp?id=" + s;
to_server.print("GET " + filename + "\n\n");
to_server.flush(); // Send it right now!
//This response gives only only the response to the first
//request,....
byte[] buffer = new byte[4096];
int bytes_read;
while((bytes_read = from_server.read(buffer)) != -1)
to_file.write(buffer, 0, bytes_read);
to_file.close();
socket.close();
catch (Exception e) {
System.err.println(e);
System.err.println("Usage: java HttpClient <URL> [<filename>]");
}

There are many things wrong with your code. Learn the HTTP protocol and you'll know what I mean.
Here's a hint - you'r missing headers in your code.
Some servers do not support keep-alive connections, nor do you request a keep-alive connection.
Connection: keep-alive
Use that header field and see what happends. Also, in your while-loop, you actually close the output file and the socket. Don't you think it may be hard for the server to respond to a client that closed the connection on it?
1. You don't know HTTP
2. You don't seem to know Java
3. You don't seem to understand basic programming logic
