Vista unzip performance, PNG files and more

I) Unzip speed.

I found an easy work around for my unzip issue; it's called PODP (Plain Old Dos Promt). Thanks to C. Spieler, I can execute unzip from the command line.
C:\Users\erajkovi\Downloads>unzip sqldeveloper-1.1.2.2579-no-jre.zip -d \opt
II) Screen capture and files size.

This may just be a fact: PNG is far from giving you a compression level that is comparable to JPEG on Windows Vista, using Paint. I have done a screen capture of my full desktop screen (1280x1024) and save it in PNG, as I was becoming acoustate to use open formats. The bottom line:

I must be doing something wrong...

III) SQL Developer Migration Workbench Early Adopter for public evaluation is out !!!

png vs jpg

Nothing wrong here. PNG is the successor to GIF and not JPG.

JPG->photos
PNG-> cartoon like drawings

Thanks for the correction - I was misslead by the statement that PNG are good for Windows screenshoot.

Changing the version of JDK used by JDeveloper

I have recently learned a quick and lazy way to change the version of the JDK used to run JDeveloper 10g R3. I am sure there is an option somewhere in the configuration screen to do the same, which I couldn't find... While JDeveloper is not running, locate the embedded JDK on disk and rename (or delete) that directory. For me, it was C:\opt\jdev\jdk. Once it's done, restart and you will by asked to locate the version of the JDK you want to use. It's another step to get going with JAVA on Vista. -ecco

Connection reset from a WCF Web Service

Here is an error message you may see, when calling WCF Web Services from java: IOException retrieving the response: java.net.SocketException: Connection reset As it may not be obvious the first time you see it, this may save you some time. One reason for this behaviour is when the WCF endpint is expecting to see wsa:Action SOAP header in the request. To find out if you are facing this case, you have to look inside the WSDL, and search for the policy that describes the contract for your endpoint. <wsp:Policy wsu:Id="CustomBinding_Echo1_policy">   <wsp:ExactlyOne>     <wsp:All>       <wsaw:UsingAddressing/>     </wsp:All>   </wsp:ExactlyOne> </wsp:Policy> To make this a concrete example, here is a sample WSDL . To find the policy, you will need to follow the import as the policy are not always advertized in the top-level document. Here is how the import looks:   <wsdl:import namespace="http://example.org/" location="h

There is a challenge that is hard to overcome at first; making sense of error messages. You can always Google with the text of the error, “unexpected null value for literal data” and hope to be lucky . If you are using Oracle Application Server 10.1.3.0, here is the explaination for the message and two ways out. The Exception: unexpected null value for literal data at oracle.j2ee.ws.common.util.exception.JAXRPCExceptionBase.<init>(JAXRPCExceptionBase.java:52) at oracle.j2ee.ws.common.encoding.SerializationException.<init>(SerializationException.java:26) ... The relevant schema: <complexType name="Customer"> <sequence> <element name="address" type="tns:Address"/> <element name="firstName" type="string"/> <element name="lastName" type="string"/> </sequence> </complexType> A sample code that will cause this exception: public void testServ() throw
