JAVA Webstart 7

Hello

We have PO 7.4 installed and we are unable to open the Integration builder.

It says Application error ->unable to launch application.

The detail error shows the following

nvalidArgumentException[ Invalid arguments supplied: { }]

  at com.sun.javaws.Main.continueInSecureThread(Unknown Source)

  at com.sun.javaws.Main.access$000(Unknown Source)

  at com.sun.javaws.Main$1.run(Unknown Source)

  at java.lang.Thread.run(Unknown Source)

We have installed Java Webstart 7 and I had even tried adding the PI url in the exception list of JWS.

It did not work. Is this error related to JWS or anything else?

Regards

Krish

    Hello Krish,

    There was a known bug in JRE 7 which caused this error. This has been fixed in later JRE updates, so please ensure that you have updated your JRE 7 installation. Refer to the SAP Note 1770625 for more details.

    Alternatively, you can install JRE 6 or JRE 8 and use them when opening ESR / Integration Directory.

    Regards,

    Vadim

    Hi

    I have now loaded JAVA 6.

    But my IE by default goes for JAVA 7 when I click the PI url.

    Regards

    • It will use the default JRE which is configured in your system. If you would like to use alternative JRE (for example, JRE 7 is the default one, and you would like to run JNLP like ESR or Integration Directory using newly installed JRE 6), you can navigate to binaries of JRE 6 (<JRE 6 installation path>\bin\) and call javaws from there providing URL to the called JNLP as an argument for it. For example, you can download JNLP of ESR / Integration Directory from XI start page (/dir) and then use full path to those files as an argument when calling javaws of JRE 6 installation, or you can use URL pointing to their location on the PI system: for ESR - http://<host>:<HTTP port>/rep/start/sso/repository.jnlp, for Integration Directory - http://<host>:<HTTP port>/dir/start/sso/directory.jnlp.
