Hi,
Can any body give, what makes the difference between adapter and package.
An adapter allows you to connect to a resource (i.e. JDBC database, applications like SAP, etc.) without writing your own specialized code to do so. In the webMethods 6.x and IS 4.x worlds, the adapter code is stored in a package - the package is simply a way to group similar code in one place for easy maintenance and deployment.
In the webMethods Enterprise 4.x and 5.x worlds, there is no concept of “package”. Adapters still exist, with basically the same definition as above, but they are not all stored in a single package structure. Instead, you usually have a separate installation program that is run for each adapter.
