3. Porting Solaris to LinuxJava belongs to this category-general Linux technology-Linux programming and kernel information. The following is a detailed description. If the application only uses standard language components and standard libraries, and does not have to run under SolarisS on the iSCSI processor, porting is easier. For example, Java applications generally fall into this category. On the other hand, if the application does not use the POSI
