684 IBM Eserver i5 and iSeries System Handbook

Compatibility

򐂰 IBM Toolbox for Java no longer ships the x4j400.jar (IBM XML parser). We

recommend that you use one of the following JAXP-compliant XML parsers

for your applications:

– The XML parser that is built into JDK 1.4 and higher

– The Apache Xerces XML parser available from:

http://xml.apache.org/

– One of the XML parsers that ship on OS/400 under

/QIBM/ProdData/OS400/xml/lib

򐂰 IBM Toolbox for Java no longer supports running in the default JVM in

Netscape Navigator or Microsoft Internet Explorer. For applets that use IBM

Toolbox for Java classes to run in a browser, install a plug-in such as the Sun

Java 2 Runtime Environment (JRE) 1.3.0 plug-in.

򐂰 The classes that were in data400.jar are now in jt400.jar.

򐂰 The getObject() methods for ResultSet and CallableStatement now return

Integer objects when the SQLType is SMALLINT. Previously, these methods

returned Short objects. If you use readObject to read SMALLINT columns,

you must alter your Java application to accommodate the new type of

returned object.

򐂰 Different error reporting when throwing data truncation errors results in

warnings that do not cause your application to fail.

򐂰 You cannot use this release of IBM Toolbox for Java to deserialize some

objects that you serialized using releases prior to V5R1.

򐂰 If you are using SSL to encrypt data flowing between the client and the server,

you must use one of the following options:

– Java Secure Socket Extension (JSSE)

– SSL objects delivered in a V5R1 or later version of iSeries Client

Encryption licensed program 5722-CE2 or 5722-CE3. This release of IBM

Toolbox for Java does not work with V4R5 and earlier versions of iSeries

Client Encryption.

򐂰 To use all the IBM Toolbox for Java classes, use the Java 2 Platform Standard

Edition (J2SE). Using the vaccess classes or the Graphical Toolbox requires

using the Swing package, which comes with J2SE. Using PDML requires that

you run version 1.4 or later of the JRE.
