Java Desktop API broken on windows?

809103Jul 31 2011 — edited Nov 14 2011
From what I can tell no-one has actually been able to get this API to work properly..

Desktop dtop = Desktop.getDesktop();
dtop.open(new File("/test.mp3"));

always results in the error:
Exception in thread "main" java.io.IOException: Failed to open file:/D:/TMP/test.mp3. Error message: Unspecified error

at sun.awt.windows.WDesktopPeer.ShellExecute(Unknown Source)
at sun.awt.windows.WDesktopPeer.open(Unknown Source)

at com.test.Test.<init>(Test.java:50)
at com.test.Test.main(Test.java:103)
ERROR: JDWP Unable to get JNI 1.2 environment, jvm->GetEnv() return code = -2
JDWP exit error AGENT_ERROR_NO_JNI_ENV(183): [../../../src/share/back/util.c:820]

I've tried using browse, as well no luck.
and yes (I can open the file directly, and yet..its is associated, and I've run the process as admin -- yes this on a windows 7 x64 machine).

its works fine for .txt files.

I have seen various postings on bugs related to this..but mysteriously those bugs have 'vanished' from the system.

Regarding writing to Oracle, start by reading the https://oracle.github.io/node-oracledb/doc/api.html
Consuming "a web service" can be done with the http module which is part of Node.js. Check out the manual and doc like https://nodejs.org/en/knowledge/HTTP/clients/how-to-create-a-HTTP-request/

Why nodejs and not use only PL/SQL? Far fewer moving parts.

i am not sure on how pl/sql works , Appreciate if you can post some links. All i want is to read the url and insert data into Oracle table.

Oracle has the UTL_HTTP package API and the HttpUriType advance datatype (oo class).
Sample code provided in manual and you can also look at https://community.oracle.com/tech/developers/discussion/comment/10450611/#Comment_10450611 and as for the oo class:

SQL> select httpuritype( 'http://google.com' ).getClob() as "HTML" from dual;

HTML
-------------------------------------------------------------------------------
<!doctype html><html itemscope="" itemtype="http://schema.org/WebPage" lang="en
-ZA"><head><meta content="text/html; charset=UTF-8" http-equiv="Content-Type">
..snipped..

In PL/SQL use:

clobVariable := new HttpUriType(urlVariable).getClob();
