I just received the update for Java 7 on a client laptop. I have an idea that update of software is a good thing it keeps the system updated and hopefully have fewer security problems. It seems to be a recurring issue with the Java platform.
I wanted to start my development with SAP PI and the Integration Builder tools. So I was looking forward to see how it would perform. I have seen the Java 7 update on a terminal server on another client. Here there java 7 was unable to start the Enterprise Service Builder or Integration Builder.
On my client laptop I was able to start both tools on the PI 7.31 systems. It did take quite a long time and when they finally started they were using 300mb. In Java 6 they only took up 200mb when they started. If you have 4 windows open then it is the difference in using the swap file or not.
My challenges are that I was not able to start the java 7 version always and it took forever to start, if it did decide to start. So I had to find a way to use the Java 6 WS to run the tools.
The easiest was to use a Windows Shortcut to manage and start the tools. So I created a shortcut for each system and then in the target I had the following information
"C:\Program Files\Java\jdk1.6.0_35\jre\bin\javaws.exe" http://server:54000/rep/start/sso/repository.jnlp
C:\Program Files\Java\jdk1.6.0_35\jre\bin\javaws.exe" http://server:54000/dir/start/sso/directory.jnlp
The javaws needs to be updated to where you are locating your java 6 WS and the server url should be updated to point to your server.
Then I could just copy the shortcuts for PID, PIT and PIP, and just changed the server and port. I now have 6 shortcuts to start the PI tools with. The single sign on does not work, but I can manage to enter my password when starting the Swing tools.
