(JRMP) 30 .SH SYNOPSIS 31 .PP 32 \f[CB]rmic\f[R] [\f[I]options\f[R]] 33 \f[I]package\-qualified\-class\-names\f[R] 34 .TP 35 .B \f[I]options\f[R] 36 This represent the command\-line \f[CB]options\f[R] for the\f[CB]rmic\f[R] 37 compiler. 38 See \f[B]Options for the rmic Compiler\f[R]. 39 .RS 40 .RE 41 .TP 42 .B \f[I]package\-qualified\-class\-names\f[R] 43 Class names that include their packages, for example, 44 \f[CB]java.awt.Color\f[R]. 45 .RS 46 .RE 47 .SH DESCRIPTION 48 .PP 49 \f[B]Deprecation Note:\f[R] Support for static generation of Java Remote 50 Method Protocol (JRMP) stubs and skeletons has been deprecated. 51 Oracle recommends that you use dynamically generated JRMP stubs instead, 52 eliminating the need to use this tool for JRMP\-based applications. 53 .PP 54 The \f[CB]rmic\f[R] compiler generates stub and skeleton class files using 55 the JRMP. 56 .PP 57 \f[B]Note:\f[R] 58 .PP 59 The rmic compiler has been updated to remove the \f[CB]\-idl\f[R] and 60 \f[CB]\-iiop\f[R] options and can no longer generate IDL or IIOP stubs and 61 tie classes. 62 .PP 63 JRMP class files are generated from compiled Java programming language 64 classes that are remote object implementation classes. 65 A remote implementation class is a class that implements the interface 66 \f[CB]java.rmi.Remote\f[R]. 67 The class names in the \f[CB]rmic\f[R] command must be for classes that 68 were compiled successfully with the \f[CB]javac\f[R] command and must be 69 fully package qualified. 70 For example, running the \f[CB]rmic\f[R] command on the class file name 71 \f[CB]HelloImpl\f[R] as shown here creates the 72 \f[CB]HelloImpl_Stub.class\f[R] file in the \f[CB]hello\f[R] subdirectory 73 (named for the class\[aq]s package): 74 .RS 75 .PP 76 \f[CB]rmic\ hello.HelloImpl\f[R] 77 .RE 78 .PP 79 A skeleton for a remote object is a JRMP protocol server\-side entity 80 that has a method that dispatches calls to the remote object 81 implementation. 82 .PP 83 A stub is a client\-side proxy for a remote object that\[aq]s 84 responsible for communicating method invocations on remote objects to 85 the server where the actual remote object implementation resides. 86 A client\[aq]s reference to a remote object, therefore, is actually a 87 reference to a local stub. 88 .PP 89 By default, the \f[CB]rmic\f[R] command generates stub classes that use 90 the 1.2 JRMP stub protocol version only, as though the \f[CB]\-v1.2\f[R] 91 option were specified. 92 See \f[B]Options for the rmic Compiler\f[R]. 93 .PP 94 A stub implements only the remote interfaces, and not local interfaces 95 that the remote object also implements. 96 Because a JRMP stub implements the same set of remote interfaces as the 97 remote object, a client can use the Java programming language built\-in 98 operators for casting and type checking. 99 .PP 100 \f[B]Note:\f[R] 101 .PP 102 The rmic compiler does not support reading of class files that have been 103 compiled with the \f[CB]\-\-enable\-preview\f[R] option, nor does it 104 support generation of stub or skeleton classes that have preview 105 features enabled. 106 .SH OPTIONS FOR THE RMIC COMPILER 107 .TP 108 .B \f[CB]\-bootclasspath\f[R] \f[I]path\f[R] 109 Overrides the location of bootstrap class files. 110 .RS 111 .RE 112 .TP 113 .B \f[CB]\-classpath\f[R] \f[I]path\f[R] 114 Specifies the path the \f[CB]rmic\f[R] command uses to look up classes. 115 This option overrides the default or the \f[CB]CLASSPATH\f[R] environment 116 variable when it is set. 117 Directories are separated by colons or semicolons, depending on your 118 operating system. 119 The following is the general format for \f[I]path\f[R]: 120 .RS 121 .IP \[bu] 2 122 \f[B]Oracle Solaris, Linux, and OS X:\f[R] 123

this option to specify a destination directory for the stub, 134 skeleton, and tie files. 135 .RS 136 .IP \[bu] 2 137 \f[B]Oracle Solaris, Linux, and OS X:\f[R] For example, the following 138 command

option isn\[aq]t specified, then the default 158 behavior is as though \f[CB]\-d\f[R] was specified. 159 The package hierarchy of the target class is created in the current 160 directory, and stub/tie/skeleton files are placed within it. 161 .RE 162 .TP 163 .B \f[CB]\-g\f[R] 164 Enables the generation of all debugging information, including local 165 variables. 166 By default, only line number information is generated. 167 .RS 168 .RE 169 .TP 170 .B \f[CB]\-J\f[R]\f[I]argument\f[R] 171 Used with any Java command, the \f[CB]\-J\f[R] option passes the 172 \f[I]argument\f[R] that follows it (no spaces between the \f[CB]\-J\f[R] 173 and the argument) to the Java interpreter. 174 .RS 175 .RE 176 .TP 177 .B \f[CB]\-keep\f[R] or \f[CB]\-keepgenerated\f[R] 178 Retains the generated \f[CB]\&.java\f[R] source files for the stub, 179 skeleton, and tie classes and writes them to the same directory as 180 the\f[CB]\&.class\f[R] files. 181 .RS 182 .RE 183 .TP 184 .B \f[CB]\-nowarn\f[R] 185 Turns off warnings. 186 When the \f[CB]\-nowarn\f[R] options is used, the compiler doesn\[aq]t 187 print warnings. 188 .RS 189 .RE 190 .TP 191 .B \f[CB]\-nowrite\f[R] 192 Doesn\[aq]t write compiled classes to the file system. 193 .RS 194 .RE 195 .TP 196 .B \f[CB]\-vcompat\f[R] (deprecated) 197 Generates stub and skeleton classes that are compatible with both the 198 1.1 and 1.2 JRMP stub protocol versions. 199 This option was the default in releases before 5.0. 200 The generated stub classes use the 1.1 stub protocol version when loaded 201 in a JDK 1.1 virtual machine and use the 1.2 stub protocol version when 202 loaded into a 1.2 (or later) virtual machine. 203 The generated skeleton classes support both 1.1 and 1.2 stub protocol 204 versions. 205 The generated classes are relatively large to support both modes of 206 operation. 207 .RS 208 .PP 209 \f[B]Note:\f[R] 210 .PP 211 This option has been deprecated. 212 See \f[B]Description\f[R]. 213 .RE

\f[CB]\-v1.1\f[R] (deprecated) 222 Generates stub and skeleton classes for the 1.1 JRMP stub protocol 223 version only. 224 The \f[CB]\-v1.1\f[R] option is useful only for generating stub classes 225 that are serialization\-compatible with existing, statically deployed 226 stub classes generated by the \f[CB]rmic\f[R] command from JDK 1.1 that 227 can\[aq]t be upgraded (and dynamic class loading isn\[aq]t being used). 228 .RS 229 .PP 230 \f[B]Note:\f[R] 231 .PP 232 This option has been deprecated. 233 See \f[B]Description\f[R]. 234 .RE 235 .TP 236 .B \f[CB]\-v1.2\f[R] (deprecated) 237 (Default) Generates stub classes for the 1.2 JRMP stub protocol version 238 only. 239 No skeleton classes are generated because skeleton classes aren\[aq]t 240 used with the 1.2 stub protocol version. 241 The generated stub classes don\[aq]t work when they\[aq]re loaded into a 242 JDK 1.1 virtual machine. 243 .RS 244 .PP 245 \f[B]Note:\f[R] 246 .PP 247 This option has been deprecated. 248 See
