java - 如何在java中将字符串转换为CCSID 37

Question

我想将 java 字符串“HelloWorld”转换为 CCSID 37 数字。但我在java中找不到任何API来做到这一点。

CCSID37

Answer 1

你可以这样尝试:

String.getBytes(System.getProperty("com.ibm.cics.jvmserver.local.ccsid"))
String(bytes, System.getProperty("com.ibm.cics.jvmserver.local.ccsid"))

The JCICS API uses the code page that is specified in the CICS region and not the underlying JVM. So if the JVM uses a different file encoding, your application must handle different code pages. To help you determine which code page CICS is using, CICS provides several Java properties:

• The com.ibm.cics.jvmserver.supplied.ccsid property returns the code page that is specified for the CICS region. By default, the JCICS API uses this code page for its character encoding. However, this value
  can be overridden in the JVM server configuration.
• The com.ibm.cics.jvmserver.override.ccsid property returns the value of an override in the JVM profile. The value is a code page that the JCICS API uses for its character encoding, instead of the code page that is used by the CICS region.
• The com.ibm.cics.jvmserver.local.ccsid property returns the code page that the JCICS API is using for character encoding in the JVM server.
