A manifest file

The manifest file specifies the names of the deployment descriptor files that a JAR file contains. The m option of the jar command incorporates the manifest file into the default manifest of the JAR. Starting with Informix 14.10, the manifest file can also specify a properties file used to describe automated registration. See Automatic Deployment (Enhanced Class Deployment )

The following example shows the manifest file, manifest.txt, for a JAR with two deployment descriptors: 
Name: deploy1.txt
SQLJDeploymentDescriptor: TRUE

Name: deploy2.txt
SQLJDeploymentDescriptor: TRUE
The following example shows the jar command that incorporates manifest.txt into a JAR file: 
jar cvmf manifest.txt admin.jar deploy*.txt *.class
