JAVA Webstart 7


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$ Source)

  at 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?

    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.

    I have now loaded JAVA 6.

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

    • 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.
