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.

    Good to know that we can create a shortcut , I was typing the whole path of javaws every time and used to download the repository/directory.jnlp files to open the same ….time saving tip..thanks for sharing this tip.

    Hi Daniel – This alternative solution can also be used to avoid issues with changes in java 8 security settings.

    May be you can add the tag java8 or change the title to working with multiple version of java so that it can be easily found

    Thank you

    On our system Java 6 has been removed completely and replaced by Java 7. I don’t have admin rights so cannot download 6. Is there any workaround for me as I cannot access IB or ESB of SAP PI?

    Thank you in advance. All help greatly appreciated! 🙂
