13.5.1 About the ojvmtc Tool

The ojvmtc tool enables you to resolve all external references, prior to running the loadjava tool. The ojvmtc tool allows the specification of a classpath that specifies the JARs, classes, or directories to be used to resolve class references. When an external reference cannot be resolved, this tool either produces a list of unresolved references or generated stub classes to allow resolution of the references, depending on the options specified. Generated stub classes throw a java.lang.ClassNotfoundException if it is referenced at runtime.

The syntax is:

ojvmtc [-help ] [-bootclasspath] [-server connect_string] [-jar jar_name] [-list] -classpath jar1:path2:jar2  

For example:

ojvmtc -bootclasspath $JAVA_HOME/jre/lib/rt.jar -classpath classdir/lib1.jar:classdir/lib2.jar -jar set.jar app.jar

The preceding example uses rt.jar, classdir/lib1.jar, and classdir/lib2.jar to resolve references in app.jar. All the classes examined are added to set.jar, except for those found in rt.jar.

Another example is:

ojvmtc -server thin:HR/@localhost:5521:orcl -classpath jar1:jar2 -list app2.jar

The preceding example uses classes found in the server specified by the connection string as well as jar1 and jar2 to resolve app2.jar. Any missing references are displayed to stdout.

13.5.2 Arguments of ojvmtc Command

Table 13-1 summarizes the arguments of this command.

Table 13-1 ojvmtc Argument Summary

Argument Description


Uses the specified JARs and classes for the closure set.


Uses the specified classes for closure, but does not include them in the closure set.

-server connect_string

Connects to the server using visible classes in the same manner as -bootclasspath.

connect_string thin|OCI

Connects to the server using thin or Oracle Call Interface (OCI) specific driver.

If you use thin driver, the syntax is as follows:


If you use OCI driver, the syntax is as follows:

oci:user/passwd@(connect descriptor)

-jar jar_name

Writes each class of the closure set to a JAR and generates stubs for missing classes


Lists the missing classes.
