  • Migrating Forms to Java or ADF, the truth and no FUD

    - by Grant Ronald
    The question about migrating Forms to Java (or ADF or APEX) comes up time and time again.  I wanted to pull some core information together in a single blog post to address this question. The first question I always ask is "WHY" - Forms may still be a viable option for you so "if it ain't broke don't fix it".  Bottom line is whatever anyone tells you, its going to be a considerable effort and cost to migrate from Forms to something else so the business is going to want to know WHY you spend all those hard earned dollars switching from something that might have been serving you quite adequately. Second point, if you are going to switch, I would encourage you NOT to look at building a Forms clone.  So many times I see people trying to build an ADF application and EXACTLY mimic the Forms model - ADF is NOT a Forms clone.  You should be building to the sweet spot of your target technology, not your 20 year old client/server technology.  This is also the chance for the business to embrace change, so maybe look at new processes, channels and technology options that weren't available when you first developed your Forms applications. To help you understand what is involved, I've put together a number of resources. Thinking about migration of Forms to Java, ADF or APEX, read this to prepare yourself Oracle Forms to ADF: When, Why and How - this gives you an overview of our vision, directly from Oracle Product Management Redeveloping a Forms Application with Oracle JDeveloper and Oracle ADF.  This is a conference session from myself and Lynn Munsinger on how ADF can be used in a Forms migration/rewrite As someone who manages both Forms and ADF Product Management teams, I've a foot in either camp and am happy to see you use either tool.  However, I want you to be able to make an informed decision.  My hope is that there information sources will help you do that.

  • Security Alert for CVE-2010-0886 and CVE-2010-0887 Released

    - by eric.maurice
    Hi, this is Eric Maurice again! Oracle just released a Security Alert to announce the availability of fixes for two vulnerabilities (CVE-2010-0886 and CVE-2010-0887) affecting Oracle Java SE and Oracle Java For Business. Both vulnerabilities only affect Java when running in a 32-bit web browser. These vulnerabilities are not present in Java running on servers or standalone Java desktop applications and do not impact any Oracle server based software. The first vulnerability (CVE-2010-0886) affects the Java Deployment Toolkit (version 6 update 10 through 19) on Windows only. The second vulnerability (CVE-2010-0887) affects the Java Plug-in (version 6 update 18 and 19) on Windows, Solaris and Linux. Both vulnerabilities may allow an attacker to run commands on the user's system with the privileges of the user, whose system may have become compromised by visiting a malicious web site. Oracle rated the severity of both vulnerabilities with a CVSS Base Score of 10.0 because many Windows users grant themselves administrative privileges. However, on other platforms, or for Windows users with limited privileges, the CVSS Base Score is only 7.5, because a successful exploitation of these vulnerabilities cannot result in a full compromise of the affected system. Users can quickly determine if they are running vulnerable versions of Java by pointing their browser to http://www.java.com/en/download/help/testvm.xml. Java SE users can visit http://www.java.com and download the most recent release of Java SE to address these vulnerabilities. Because of the criticality of these vulnerabilities, and the publicity they received as a result of their disclosure before the availability of a fix, Oracle recommends that all customers and Java users update their Java installation to the most recent version (6 update 20). For More Information: The advisory for the Security Alert for CVE-2010-0886 and CVE-2010-0887 is located at http://www.oracle.com/technology/deploy/security/alerts/alert-cve-2010-0886.html

  • Sorting XML generated by Castor

    - by Java Guy
    Hello, I am using Castor for XML Binding.. We need to sort the XML based on two different fields. Is there way we can specify the sort order in castor while marshalling? Which will be a better approach to do this sorting, if castor don't have this feature.

  • JavaCC: Please give me links to "real" examples.

    - by java.is.for.desktop
    Hello, everyone! I know that there are many examples of JavaCC parsers here, but they all do nothing. They just accept a string, or produce parsing errors. What I need is a few examples of real parsers, which actually do something during parsing. (Such as building a DOM tree during parsing an XML string). Please help! ;)

  • Edit Contact code worked in 1.6 but doesn't work on Droid 2.1?

    - by user225405
    Hi All, I had some fairly simple code in my app to invoke Edit Contact activity on a known good contact index that worked in Android 1.6 but is broken for me now in Android 2.1 on the Droid. I built a sample activity/app 'EdCon' to show this: package com.jbh; import android.app.Activity; import android.content.Intent; import android.net.Uri; import android.os.Bundle; public class EdCon extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // Build an intent to edit a known good contact index Intent i; i = new Intent(Intent.ACTION_EDIT); i.setData(Uri.parse("content://contacts/people/10")); startActivity(i); } } When I run this on my G1 running 1.6 it works as expected i.e. brings up the Edit Contact screen for the known index and then I can hit BACK to return to "Hello World, EdCon". When I run this on the Droid under 2.1 I get the following: 05-07 15:35:57.787: INFO/ActivityManager(1013): Starting activity: Intent { act=android.intent.action.MAIN

  • Problem in implementing IAlertUpdateHandler interface

    - by TheVillageIdiot
    I've implemented IAlertUpdateHandler interface in a class and used it for handling creation and updating of alerts. The code is fired but it goes into endless loop by calling itself again and again. Actually I want to suppress email notification so I'm calling a.Update(false); but this again calls PreUpdate or PostUpdate method and there is StackOverFlowException :( I've tried returning true/false from both the methods but nothing is helping.

  • Reasonable technological solutions to create CRM using .NET eventually Java

    - by user1825608
    My background(If it's too long, just skip it please ; ) ): I am Java programmer(because of demand): mostly teacher for other students, worked on few thesis for others, but during my journey I discovered that .NET and Microsoft's tools are on at least two levels higher than Java and its tools so I want to learn more about them. I programmed little bit on Windows Phone(NFC Tags, TCP Clients, guitar tuner using internal microphone, simple RSS), used WPF, integrated WPF with Windows Forms, Apple Bonjour(.NET), I have expierience with IP cameras and with unusal problems, I learn Android, but I don't like it at all. Problem: I was asked by my friend to create CRM for small new company. There will maximum 20 workers in the company working at computers in few cities in the country(Poland). They just want to store contracts with the clients and client's data. I am not sure what exacly they do but probably sell apartments so there will be at most few thousands of contracts to store in far future. Now I am totally new to CRM but I want to learn. I have few questions: Should the data be stored on a server in the company's building running 24/7 or cloud. If cloud which one? Should I use ASPX or WPF. I read one topic about it but as far as I know aspx sites can be viewed from every device with internet browser: tablets, phones(Android, WP, iOS) and computers at the same time- so the job is done once and for all(Am I right?), I don't know nothing about aspx. Can WPF be also used in manner that does not need to port it for other platforms?

  • C#: standard Windows menu bars in Windows Forms

    - by BoltClock
    I noticed that adding a MenuStrip (from the VS Toolbox) to my form design doesn't yield a menu bar like many native Windows applications. Instead I get a menu bar like VS's own. None of the style settings for MenuStrip appear to mimic the much more common native menu bar. Is there a way to add a menu bar to my Windows Forms application that looks the same as the one you see in Notepad, Task Manager, Windows Explorer and others? (Preferably with the designer, but I wouldn't mind adding it programmatically either.)

  • Job queue manager with RPC interface

    - by admr
    I need a job queue manager that I can control over the Internet. It should be able to execute and stop processes, check on their status (ideally notice and execute some code when a process exits), respond to commands and also be able to report back to a server. Background: I have a GWT application that allows to create jobs to execute on a cloud instance (currently EC2). I want to push a "job packet" (data for a process to operate on etc) to S3, start a Linux EC2 instance (or use one that's already running), and tell a job manager on the instance to execute that job (possibly parallel to other jobs). It should then pull the "job packet" from S3, run a process that operates on that data and report back to the server that is running the server part of my GWT application with some information (e.g. exit code, stdout, stderr). If I have to write e.g. stdour/err to a file from the process and read that file, that's OK too. I would really like the manager to be "close" to the processes it runs, meaning I want to avoid using something like Runtime.exec from the JDK. It seems like I would have to do that if I used Quartz for example. I'm fine with the calls in both directions being asynchronous. I'm fine with any reasonable technology for the calls as long as I can easily build an interface for that in my GWT server side (e.g. HTTP requests to a servlet over SSL would be nice and trivial). The job manager does not need to have a very sophisticated queueing system. Running several processes either sequentially or in parallel should be fine. Determining how much compute time a process received during its lifetime would be nice (AFAIK, this might be challenging). I did not yet find any existing software that does this, including http://java-source.net/open-source/job-schedulers. I suspect I might have to build an RPC interface (with authentication etc, of course) around a job manager; maybe use something like Apache Commons Exec. In that case, I would prefer Java or Python for the job manager part. I would be happy to hear suggestions for either the former or latter scenario!

  • virtual memory commited

    - by vinu
    After a server bounce happens, and after around 40-45 days time period, we receive continuous “Committed Virtual Memory” alerts which indicates the usage of swap space in the magnitude of 4GB This also causes the application to perform very slowly and experience a number of stalled transactions. Server Setup: 4 Tomcat Servers (version 7.0.22) that are load balanced (not clustered) by 2 Apache Servers. And the Apache servers themselves supply static content and routing to these 4 tomcat servers. Java Runtime Version: java version "1.6.0_30" Java(TM) SE Runtime Environment (build 1.6.0_30-b12) Java HotSpot(TM) 64-Bit Server VM (build 20.5-b03, mixed mode Memory Startup Parameters: MEMORY_OPTIONS="-Xms1024m -Xmx1024m -Xss192k -XX:MaxGCPauseMillis=500 -XX:+HeapDumpOnOutOfMemoryError -XX:MaxPermSize=256m -XX:+CMSClassUnloadingEnabled" Monitoring – Wily monitoring is available in all the production servers that monitors key server parameters and sends out configurable alert emails based on pre defined settings. Note: Each of the servers also has two other separate tomcat domains that run different applications Investigated area: There is no Heap Memory Leak and the GC is running fine without any issues over any period of time The current busy thread count corresponds directly to the application usage – weekends and nights have lesser no. of threads compared to business hours ThreadLocal uses a WeakReference internally. If the ThreadLocal is not strongly referenced, it will be garbage-collected, even though various threads have values stored via that ThreadLocal. Additionally, ThreadLocal values are actually stored in the Thread; if a thread dies, all of the values associated with that thread through a ThreadLocal are collected. If you have a ThreadLocal as a final class member, that's a strong reference, and it cannot be collected until the class is unloaded. But this is how any class member works, and isn't considered a memory leak. The cited problem only comes into play when the value stored in a ThreadLocal strongly references that ThreadLocal—sort of a circular reference. In this case, the value (a SimpleDateFormat), has no backwards reference to the ThreadLocal. There's no memory leak in this code. Can anyone please let me know what could be the cause of this and what to be monitored?

  • Recommendations for a C++ polymorphic, seekable, binary I/O interface

    - by Trevor Robinson
    I've been using std::istream and ostream as a polymorphic interface for random-access binary I/O in C++, but it seems suboptimal in numerous ways: 64-bit seeks are non-portable and error-prone due to streampos/streamoff limitations; currently using boost/iostreams/positioning.hpp as a workaround, but it requires vigilance Missing operations such as truncating or extending a file (ala POSIX ftruncate) Inconsistency between concrete implementations; e.g. stringstream has independent get/put positions whereas filestream does not Inconsistency between platform implementations; e.g. behavior of seeking pass the end of a file or usage of failbit/badbit on errors Don't need all the formatting facilities of stream or possibly even the buffering of streambuf streambuf error reporting (i.e. exceptions vs. returning an error indicator) is supposedly implementation-dependent in practice I like the simplified interface provided by the Boost.Iostreams Device concept, but it's provided as function templates rather than a polymorphic class. (There is a device class, but it's not polymorphic and is just an implementation helper class not necessarily used by the supplied device implementations.) I'm primarily using large disk files, but I really want polymorphism so I can easily substitute alternate implementations (e.g. use stringstream instead of fstream for unit tests) without all the complexity and compile-time coupling of deep template instantiation. Does anyone have any recommendations of a standard approach to this? It seems like a common situation, so I don't want to invent my own interfaces unnecessarily. As an example, something like java.nio.FileChannel seems ideal. My best solution so far is to put a thin polymorphic layer on top of Boost.Iostreams devices. For example: class my_istream { public: virtual std::streampos seek(stream_offset off, std::ios_base::seekdir way) = 0; virtual std::streamsize read(char* s, std::streamsize n) = 0; virtual void close() = 0; }; template <class T> class boost_istream : public my_istream { public: boost_istream(const T& device) : m_device(device) { } virtual std::streampos seek(stream_offset off, std::ios_base::seekdir way) { return boost::iostreams::seek(m_device, off, way); } virtual std::streamsize read(char* s, std::streamsize n) { return boost::iostreams::read(m_device, s, n); } virtual void close() { boost::iostreams::close(m_device); } private: T m_device; };

    Read on before you say this is a duplicate, it's not. (as far as I could see) I want to get the county code in php from the client. Yes I know you can do this using external sites or with the likes of "geoip_record_by_name" but I don't want to be dependent on an external site, and I can't install "pear" for php as im using shard Dreamhost hosting. I thought I could just do something like this: $output = shell_exec('whois '.$ip.' -H | grep country | awk \'{print $2}\''); echo "<pre>$output</pre>"; But dreamhost seems to have an old version of whois (4.7.5), so I get this error on allot of IPs: Unknown AS number or IP network. Please upgrade this program. So unless someone knows how to get a binary of a newer version of whois onto dreamhost im stuck. Or is there another way I could get the country code from the client who is loading the page?

  • Charting library for Blackberry devices (native)

    - by dozerbull
    Does anyone know of a library to display charts and graphs natively on blackberry devices ? There are quite a few javascript (Flot...) charting libraries but I'd rather use something similar to Coreplot on iPhone if it is possible. I didn't find anything on top of SVG (JSR 226) or open GL ES (JSR 239) so any help is appreciated. Ideally, I'd like to be able to: draw Bar Charts (both vertical and horizontal) draw Stacked bar charts draw Pie charts drill-down one level on each bar or pie section to get corresponding information

  • Query column and everything subordinate (hard to describe, non native speaker, PLS let me explain)

    - by MAD9
    A few weeks ago, I asked a question about how to generate hierarchical XML from a table, that has a parentID column. It all works fine. The point is, according to the hierarchy, I also want to query a table. I'll give you an example: Thats the table with the codes: ID CODE NAME PARENTID 1 ROOT IndustryCode NULL 2 IND Industry 1 3 CON Consulting 1 4 FIN Finance 1 5 PHARM Pharmaceuticals 2 6 AUTO Automotive 2 7 STRAT Strategy 3 8 IMPL Implementation 3 9 CFIN Corporate Finance 4 10 CMRKT Capital Markets 9 From which I generate (for displaying in a TreeViewControl) this XML: <record key="1" parentkey="" Code="ROOT" Name="IndustryCode"> <record key="2" parentkey="1" Code="IND" Name="Industry"> <record key="5" parentkey="2" Code="PHARM" Name="Pharmaceuticals" /> <record key="6" parentkey="2" Code="AUTO" Name="Automotive" /> </record> <record key="3" parentkey="1" Code="CON" Name="Consulting"> <record key="7" parentkey="3" Code="STRAT" Name="Strategy" /> <record key="8" parentkey="3" Code="IMPL" Name="Implementation" /> </record> <record key="4" parentkey="1" Code="FIN" Name="Finance"> <record key="9" parentkey="4" Code="CFIN" Name="Corporate Finance"> <record key="10" parentkey="9" Code="CMRKT" Name="Capital Markets" /> </record> </record> </record> As you can see, some codes are subordinate to others, for example AUTO << IND << ROOT What I want (and have absolutely no idea how to realise or even, where to start) is to be able to query another table (where one column is this certain code of course) for a code and get all records with the specific code and all subordinate codes For example: I query the other table for "IndustryCode = IND[ustry]" and get (of course) the records containing "IND", but also AUTO[motive] and PHARM[aceutical] (= all subordinates) Its an SQL Express Server 2008 with Advanced Services.

  • iPhone Human Interface Guidelines question

    - by Kyle
    iPhone Human Interface Guidelines -- Do they apply for OpenGL games? GL games typically have custom buttons, custom lists, etc. Take the Quake player list for example, if ported, it wouldnt be a typical UI list object. Does this mean the reviewer in question would reject anything that wasn't using standard UI? Or, is there an exception for games.

  • Access violation when running native C++ application that uses a /clr built DLL

    - by doobop
    I'm reorganzing a legacy mixed (managed and unmanaged DLLs) application so that the main application segment is unmanaged MFC and that will call a C++ DLL compiled with /clr flag that will bridge the communication between the managed (C# DLLs) and unmanaged code. Unfortuantely, my changed have resulted in an Access violation that occurs before the application InitInstance() is called. This makes it very difficult to debug. The only information I get is the following stack trace. > 64006108() ntdll.dll!_ZwCreateMutant@16() + 0xc bytes kernel32.dll!_CreateMutexW@12() + 0x7a bytes So, here are some sceanrios I've tried. - Turned on Exceptions-Win32 Exceptions-c0000005 Access Violation to break when Thrown. Still the most detail I get is from the above stack trace. I've tried the application with F10, but it fails before any breakpoints are hit and fails with the above stack trace. - I've stubbed out the bridge DLL so that it only has one method that returns a bool and that method is coded to just return false (no C# code called). bool DllPassthrough::IsFailed() { return false; } If the stubbed out DLL is compiled with the /clr flag, the application fails. If it is compiled without the /clr flag, the application runs. - I've created a stub MFC application using the Visual Studio wizard for multidocument applications and call DllPassthrough::IsFailed(). This succeeds even with the /clr flag used to compile the DLL. - I've tried doing a manual LoadLibrary on winmm.lib as outlined in the following note Access violation when using c++/cli. The application still fails. So, my questions are how to solve the problem? Any hints, strategies, or previous incidents. And, failing that, how can I get more information on what code segment or library is causing the access exception? If I try more involved workarounds like doing LoadLibrary calls, I'd like to narrow it to the failing libraries. Thanks. BTW, we are using Visual Studio 2008 and the project is being built against the .NET 2.0 framework for the managed sections.
