How to recover "Open With" option of exe files on Windows XP

Accidentally or purposely, changing "Open With" option of exe files causes a fatal damages on xp that cannot be recovered. Since, the tools and all other programs are exe files and running them becomes almost impossible for an average experienced user.

Changing "Open With" Option of EXE Files
Open "My Computer" / "Local Disc" (where Windows is installed. e.g. C:) / "Windows"; then, right click on regedit.exe, select "Run As" and uncheck the box of "Protect my computer and data from unauthorized program activity" on the menu, then press OK.

Go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe; then delete all key-value pairs at .exe, OpenWithList and OpenWithProgids.

SoapUI 4.5.0 Project XML File Encoding Problem

Image
I' ve been already using SoapUI Pro 3.6.1 since license expires. Previous migrations to soapUI newer versions had not caused problems but when starting using SoapUI 4.5.0(free) version resulted destroying existing projects. I checked log file ("C:\...\SmartBear\soapUI-4.5.0\bin\soapui.log") and realised that something went wrong about encoding of soapUI project XMLs. Turkish language characters in wsdl files are located in soapUI project XMLs and they are violating cp1254 character convention and causes below exception log. 


java.io.CharConversionException: Malformed UTF-8 character: 0xc5 0x3f at org.apache.xmlbeans.impl.piccolo.xml.UTF8XMLDecoder.decode(UTF8XMLDecoder.java:80) at org.apache.xmlbeans.impl.piccolo.xml.XMLStreamReader$FastStreamDecoder.read(XMLStreamReader.java:762) at org.apache.xmlbeans.impl.piccolo.xml.XMLStreamReader.read(XMLStreamReader.java:162) at org.apache.xmlbeans.impl.piccolo.xml.PiccoloLexer.yy_refill(PiccoloLexer.java:3474) at org.apache.…

iBatis with Spring: "JavaBeansDataExchange could not instantiate result class" Exception

The below exception trace occurs when trying to select records from database to create an instance of an entity or collection of entities. As a result of not providing default constructor on the entity class.

I gave a sample entity implementation that has a constructor with string parameter and commented out default constructor. After running iBatis with Spring's framework, iBatis cannot find the default constructor and print the example stack trace. This is also pointing the basics of entity beans in Java EE, "Entity Beans must have a public default constructor".

Process Builder Demo

Image
In order to create operating system processes (even another java application), running a command, and defining an environment variable; a simple approach is succeeded by using "java.lang.ProcessBuilder" class in Java.

Process process = Runtime.getRuntime().exec("cmd /c java -cp bin B"); BufferedReader inputStream = new BufferedReader(new InputStreamReader(process.getInputStream())); String line; while( (line = inputStream.readLine()) != null) { // inputStream is enabling this thread(main method) // to read "System.out" prints of started process (B.main method) System.out.println("#read from inputStream: " + line); }
The above example illustrates how to start a java application from another one. /c option has vital importance since the rest of the parameters that command line is fed to run them properly. java command must be in environment variables to run B (which consists the "main(String[] args)" method) and -cp is standart java …
