Method Details

setOutputStreamAccessAllowed

public void setOutputStreamAccessAllowed(boolean outputStreamAccessAllowed)

Set whether getOutputStream() access is allowed.

Default is true.

isOutputStreamAccessAllowed

public boolean isOutputStreamAccessAllowed()

Return whether getOutputStream() access is allowed.

setWriterAccessAllowed

public void setWriterAccessAllowed(boolean writerAccessAllowed)

Set whether getWriter() access is allowed.

Default is true.

isWriterAccessAllowed

public boolean isWriterAccessAllowed()

Return whether getOutputStream() access is allowed.

setDefaultCharacterEncoding

public void setDefaultCharacterEncoding(String characterEncoding)

Set the default character encoding for the response.

If this method is not invoked, ISO-8859-1 will be used as the default character encoding.

If the character encoding for the response has not already been explicitly set via setCharacterEncoding(String) or setContentType(String), the character encoding for the response will be set to the supplied default character encoding.

Parameters:

characterEncoding - the default character encoding

Since:

5.3.10

See Also:

• setCharacterEncoding(String)
• setContentType(String)

isCharset

public boolean isCharset()

Determine whether the character encoding has been explicitly set through HttpServletResponse methods or through a charset parameter on the Content-Type.

If false, getCharacterEncoding() will return the default character encoding.
