If Java is not installed on your system, or if you are using a third-party version of Java, you may encounter trouble running Web Client Pro. In order to correct this, follow the directions below to install Java on your operating system.
To install Java on Windows:
- Navigate to http://java.com/en/download/.
- Click Free Java Download to download the Java Runtime Environment.
- Follow the prompts to complete Java installation.
- Restart the browser, and then log in to Serv-U to start Web Client Pro.
Mac OS X
Oracle does not maintain the Java Runtime Environment on the Macintosh operating system. To install the Java Runtime Environment or to update it, use the Apple Menu > System Update menu in the Finder.
Installing Java on Linux can be complicated because most distributions ship with a third party JRE called "IcedTea", which functions differently than the Oracle JRE.
To install the official Java Runtime Environment:
- Navigate to http://java.com/en/download/linux_manual.jsp.
- Download the
Linux (Self-Extracting File)for x86-based kernels or
Linux x64for x86_64 kernels.
- Create the directory
/usr/java/, and then move the JRE into the directory.
chmod a+x jre%VER%.binto change permissions on the JRE file to allow execution.
./JRE~.binto extract the JRE to the file system.
- In 64-bit Linux, type
sudo rm /usr/lib64/mozilla/plugins/libjavaplugin.soto remove the IcedTea Java plugin, which is not supported by Web Client Pro. In 32-bit Linux, type
sudo rm /usr/lib/mozilla/plugins/libjavaplugin.so.
sudo ln -s /usr/java/jre%VER%/lib/amd64/libnpjp2.so /usr/lib64/mozilla/plugins/(or
/usr/lib/for 32-bit Linux) to allow the plugin to load in your browsers.
If SELinux is enabled, it must be configured to allow "execstack", required by Oracle Java. To do this, type
sudo setsebool -P allow_execstack 1.
