Setup RxTx jar and .so for Ubuntu

The former post describe how to "Install RXTX on Ubuntu". It simple download the files to your system, but Java not know where is it! To work with installed RxTx, you have to setup Build Path to compile the code, and copy the binaries (.so files) to java library path.

Setup Java Build Path in NetBeans:

If build path not set correctly, error of "package gnu.io does not exist" will be thrown.

"package gnu.io does not exist" thrown without Build Path set

- Right click your project, select Properties.

Setup project properties

- Select Libraries in Categories, Compiler tab and click Add JAR/Folder button.

Add JAR/Folder

- Browse to select RXTXcomm.jar, should be in /usr/share/java folder, and click OK to accept.

Add RXTXcomm.jar

- Click OK again to finish. It should be compiled without error.

Copy the binaries (.so files) to java library path:

Without corresponding .so files in java library path, you will get error of "UnsatisfiedLinkError: no rxtxSerial in java.library.path" in run time, like this:

java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path thrown while loading gnu.io.RXTXCommDriver
Exception in thread "main" java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1878)
at java.lang.Runtime.loadLibrary0(Runtime.java:849)

at serialtest.SerialTest.initialize(SerialTest.java:41)
at serialtest.SerialTest.main(SerialTest.java:109)

UnsatisfiedLinkError

- Refer to the post "Get property of java library path" to know where is the library folder.

- Copy the binaries librxtxSerial.so and librxtxParallel.so (should be in /usr/lib/jni/) to one of the library folder (for example: /opt/java/jre/lib/i386/).

$sudo cp /usr/lib/jni/librxtxSerial.so /opt/java/jre/lib/i386/librxtxSerial.so
$sudo cp /usr/lib/jni/librxtxParallel.so /opt/java/jre/lib/i386/librxtxParallel.so

Install RXTX on Ubuntu

RXTX is a full implementation of the Java CommAPI from Sun. It contains native libraries providing serial and parallel communication for the Java Development Toolkit.

A easy way to install RXTX on Ubuntu is using Synaptic Package Manager (Synaptic Package Manager is available in Ubuntu Software Center).

Simple search rxtx in Synaptic Package Manager, and mark to install

Install RxTx on Ubuntu with Synaptic Package Manager

The jars will be installed in /usr/share/java folder.

- Alternatively, you can use the command in Terminal:
$sudo apt-get install librxtx-java

Remark: It copy the files only. To make it work with Java, you have to "Setup RxTx jar and .so for Ubuntu".

Oracle official release Security Alert for US-CERT Alert, and update available.

Oracle released Security Alert for CVE-2013-0422 (US-CERT Alert TA13-010A - Oracle Java 7 Security Manager Bypass Vulnerability) and another vulnerability affecting Java running in web browsers. These vulnerabilities are not applicable to Java running on servers, standalone Java desktop applications or embedded Java applications. They also do not affect Oracle server-based software.

The fixes in this Alert include a change to the default Java Security Level setting from "Medium" to "High". With the "High" setting, the user is always prompted before any unsigned Java applet or Java Web Start application is run.

These vulnerabilities may be remotely exploitable without authentication, i.e., they may be exploited over a network without the need for a username and password. To be successfully exploited, an unsuspecting user running an affected release in a browser will need to visit a malicious web page that leverages these vulnerabilities. Successful exploits can impact the availability, integrity, and confidentiality of the user's system.

Due to the severity of these vulnerabilities, the public disclosure of technical details and the reported exploitation of CVE-2013-0422 "in the wild," Oracle strongly recommends that customers apply the updates provided by this Security Alert as soon as possible.
