 # How to call Java from SQL Server 2019 preview
 
-CTP 2.2 introduces an additional approach for calling Java from SQL Server 2019 preview. Depending on your operating system, you can adopt the following approaches:
-
-* Use the existing approach, **sp_execute_external_script**, for SQL Server on Windows or Linux.
-* Currently Windows-only in this CTP: [upload compiled Java code to an external library](#create-external-library). 
-
-## Use a system stored procedure (sp_execute_external_script)
-
 When using the [Java language extension](extension-java.md), the [sp_execute_external_script](https://docs.microsoft.com/sql/relational-databases/system-stored-procedures/sp-execute-external-script-transact-sql) system stored procedure is the interface used to call the Java runtime. Permissions on the database apply to Java code execution.
 
 This article explains implementation details for Java classes and methods that execute on SQL Server. Once you are familiar with these details, review the [Java sample](java-first-sample.md) as your next step.

-## Use DDL (CREATE EXTERNAL LIBRARY)
-
-In CTP 2.2 on Windows only, you can create an external library for compiled Java code in a jar, uploaded along with any dependencies into a database. Use the [CREATE EXTERNAL LIBRARY (Transact-SQL)](../../t-sql/statements/create-external-library-transact-sql.md) statement to upload your code:
-
-```sql
-CREATE EXTERNAL LIBRARY myJar
-FROM (CONTENT = '<local path to .jar file>') 
-WITH (LANGUAGE = 'Java'); 
-GO
-```
-
-Using an external library eliminates the classpath requirement, as well as the necessity of setting permissions on each folder in the path. You can simply call the Java class, and SQL Server will automatically have access to your classes in the library. 
-
-```sql
-EXEC sp_execute_external_script
-  @language = N'Java'
-, @script = N'MyPackage.MyCLass.myMethod'
-, @input_data_1 = N'SELECT * FROM MYTABLE'
-with result sets ((column1 int))
-```
-
-> [!Note]
-> Jar files are recommended over individual .class files. It's common practice in Java, which makes the overall experience easier.

 | Release | Feature update |
 |---------|----------------|
-| CTP 2.2 | On Windows only, Java code can be now accessed in an external library using the [CREATE EXTERNAL LIBRARY (Transact-SQL)](../t-sql/statements/create-external-library-transact-sql.md) statement. Equivalent functionality will be available on Linux in an upcoming CTP. Learn more: [How to call Java from SQL Server](java/howto-call-java-from-sql.md). |
 | CTP 2.0 | Linux platform support for R and Python machine learning. Get started with [Install SQL Server Machine Learning Services on Linux](../linux/sql-server-linux-setup-machine-learning.md). |
 |   | [Java language extension](java/extension-java.md) on both Windows and Linux is new in SQL Server 2019 preview. You can make compiled Java code available to SQL Server by assigning permissions and setting the path. Client apps with access SQL Server can use data and run your code by calling [sp_execute_external_script](https://docs.microsoft.com/sql/relational-databases/system-stored-procedures/sp-execute-external-script-transact-sql), the same procedure used for R and Python integration on SQL Server. | 
 |  | The [sp_execute_external_script](https://docs.microsoft.com/sql/relational-databases/system-stored-procedures/sp-execute-external-script-transact-sql) introduces two new parameters that enable you to easily generate multiple models from partitioned data. Learn more in this tutorial, [Create partition-based models in R](tutorials/r-tutorial-create-models-per-partition.md). |

 ### Scalar UDF inlining (CTP 2.1)
 
 Scalar UDF inlining automatically transforms scalar user-defined functions (UDF) into relational expressions and embeds them in the calling SQL query, thereby improving the performance of workloads that leverage scalar UDFs. Scalar UDF inlining facilitates cost-based optimization of operations inside UDFs, and results in efficient plans that are set-oriented and parallel as opposed to inefficient, iterative, serial execution plans. This feature is enabled by default under database compatibility level 150.
