Web collaboration and portal vendor Plumtree is hoping to broaden its appeal by extending the use of Java in its portal software.
The company is widening the use of J2EE in managing its software suite to allow application development in both Microsoft .Net or Java environments, and introduce better user interface functionality.
Charlie Abrahams, EMEA managing director at Plumtree, said: "To complete our 'openness', positioning the Java platform is very important.
"We don't have our own operating system or technology stack so we have to be as successful in our interoperability with other vendors as possible."
The launch of a Java version of Plumtree Corporate Portal 5.0J, expected in the third quarter, will enable deployments within Unix environments including Sun Solaris, IBM AIX and Linux using an extended, standards-based Java architecture.
The Java version of the portal product will be closely followed by a completely new product version, called 5.0.3.
This will include support for Windows Server 2003, application servers BEA Weblogic 8.0, IBM WebSphere 5.1 and Apache Tomcat 4.1.30, alongside any products that use WebDAV.
Combined with tighter integration with Office, these features should encourage the use of portals as primary workspaces, where all documents, emails and transactional tasks can be carried out and managed, the company said.
Plumtree will also release version 4.0 of its collaboration server in June or July, featuring increased customisation and the ability to publish documents to project groups in bulk.
The release of content server 6.0, expected in the third quarter, will give developers more control over the look, feel and functionality of portals by using an extended workflow engine or new portal creation wizard, for example.
Plumtree has also deepened integration with Office with the upcoming publication of more application programming interfaces in its Enterprise Web Development kit 8.1.
