Do you receive a message that the Deploy Tool can not locate some resource?

See Setting a Project Classpath and Setting Classpath Variables.

Use unique EJB JAR names in a project.

When creating a name for an additional property, do not use the following special symbols: slash (/), double backslash (\\), double quotation (“), colon (:), asterisk(*), question mark (?), backslash (\), greater than sign (>), less than sign (<) and vertical slash (|). They will be replaced by a tilde (~).

If you do not specify a schema name, the bean name is set by default.

Create EJB JAR files without enterprise bean class files if you have a number of applications that use common enterprise bean classes and you do not want to deploy these enterprise bean classes a number of times. Do not forget to check the specifics of this operation.

Use unique WAR names.

Use unique Servlet/JSP names in a Web archive.

Use unique listener names in a Web archive.

Use unique filter names in a Web archive.

The mapping you use to add in web xml the servlets and JSPs must be the same as their names.

Load a servlet or JSP from Files to add numerous Web components simultaneously.

Use unique resource adapter names in a project.

Use unique application client JAR names in a project.

If you make an EAR on the Assembler tab, the resulting EAR will be displayed on the Deployer tab.

Make sure the value of the session-timeout is an integer longer than the expected duration of the methods; otherwise, this will lead to system errors.

Only stateful session beans can be passivated.

If the enterprise bean uses the database table only to read from it, select the Read Only checkbox. You can obtain better performance results if you use it.

The application is not started at the end of the deployment process. It is in STOPPED mode.

With the Deploy Tool you can only start the application or application component immediately. If you want to start it at a later time, you will have to use the SAP Visual Administrator, the SAP NetWeaver or another suitable application.

If you can update a single file, consult with the documentation about the constraints.

When you update or redeploy a bean you do not need to redeploy the libraries that it has references to.
