StreamBase Client — starts the StreamBase Client, Java implementation
jsbc runs a Java implementation of the StreamBase client utility, which lets you send requests to a running StreamBase Server (sbd). For example, the jsbc list streams command requests the server to list available streams.
With a few exceptions, the jsbc command has the same options as the sbc command, as described in sbc. The exceptions are:
- No space after -u or -p
For jsbc, there must be no space between
-uand the following URI, and no space between
-pand the following port number:
jsbc -usb://localhost:10000 listConnections jsbc -p9900 listConnections
When communicating over an SSL connection, substitute
- -J option supported
The jsbc command accepts the
-Joption, but sbc does not.
Specifies a system property setting or other JVM argument to be passed to the JVM that runs this jsbc command. Use this option to specify temporary settings that affect only the current invocation of jsbc. You must specify multiple
-Joptions to specify multiple JVM arguments.
A space between the
-Jand its argument is optional. Use the full option syntax for
jvm-optionthat you would use at the Java command line, including the initial hyphen. For example, specify
-J-Dstreambase.log-level=2to increase the log level for this invocation of jsbc.
jvm-optionargument might require surrounding quotes, depending on the characters it contains and the shell you are using. However, do not use quotes to escape the spaces between separate JVM arguments; instead use separate
-Joptions. For example:
To use jsbc to communicate over SSL connections, you need to configure access to the local trustStore for command-line Java utilities in this manner, substituting actual filenames and passwords (line breaks added for readability):
jsbc -J-Djavax.net.ssl.trustStore=C:/Temp/client.keystore -J-Djavax.net.ssl.trustStorePassword=cl123abc -J-Djavax.net.ssl.keyStore=C:/Temp/client.keystore -J-Djavax.net.ssl.keyStorePassword=cl123abc -usbs://localhost:10002;user=bob;password=secret deq OUT
- Use sbs instead of sb in URI when running with a proxy server
For example, the following command connects to a proxy using Encrypted StreamBase Network Protocol over
jsbc -u"sbs://proxyhost:port;user=theuser;password=123abc" enq InputStream
- No arguments for -h and --help
Unlike the sbc command, this jsbc command's
--helpoptions do not take subcommand arguments.
The jsbc command accepts the same subcommands as the sbc command. However, note that sbc does not support Encrypted StreamBase Network Protocol. See sbc.
Optional. Contains the URI for a StreamBase Server instance. Use this variable to set a default StreamBase URI for StreamBase commands that take the
-uoption. If set, commands use the URI in this variable, overriding their built-in default URI, which is
sb://localhost:10000.If this variable is set, you must use the
-uoption to communicate with any server other than the one specified in this variable. See the sburi page in the Reference Guide for more on StreamBase URIs.
Optional. If set to any value, StreamBase programs assign a terminal window title to match the name of the executable being run. By default terminal titles are not affected. Applies to jsbc dequeue and jsbc enqueue only.
