Running Java standlone app and spring xsd error message

When running java spring based standalone application, you might get an exception that spring is not able to validate the spring beans xsd file. This might due to the fact that your computer is behind a proxy and the java application does not have access to the proxy server. 

Assuming that you have a proxy server for internet configured with host as http.myproxy.net and port 9876 then run the java application with the below options will allow the application to launch

java -Dhttp.proxyHost=http.myproxy.net -Dhttp.proxyPort=9876 -Dhttp.proxyUser=someUserName -Dhttp.proxyPassword=somePassword -jar some-jar-to-run.jar

puttycm opens putty in separate window instead of tab

PuttyCm is a good utility to open mutiple putty sessions in the same window across tabs. However there are certain problems when instead of opening in a new tab the putty session opens in a new window which is cumbersome and annoying.

There are three ways to fix this problem:
1) Timeout option
2) Windows compatibility option
3) Windows registry settings

For "Timeout option"
Tools -> Options -> Select the check-box “Enable additional timing for PuTTY capture (ms)” -> set the value to 500 ms. Try even with value of 10,000ms (~10 secs)

If that does not work then try the above with "Windows compatibility option" as indicated by this blog post

• Right-click the executable file and go to Compatibility tab.
• Choose compatibility for Windows (as per your operating system).
• Toward the bottom of the Compatibility tab, tick "Run this program as an administrator".

If both the above solutions do not work then its possible that you do not have local admin priviledges. As each time puttycm tries to open a session in a new tab then it makes an entry in the windows registry. Check with your administrator if you have local admin rights granted. Once its granted puttyCm will open new sessions in a new tab.

Android scrollview hiding top content in layout

Based on the screen layout in your Android application, some of the text in a TextView widget may not be visible i.e looks like its hidden/scrolled off at the top of the screen.

In the definition of the TextView in your layout xml, check to see if the below tag is present. This layout_gravity attribute is the problem why some of the text is not visible. Removing it from the TextView definition will display all data in the TextView widget.

android:layout_gravity="center_horizontal|center_vertical"

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ScrollView
        android:id="@+id/scrollView1"
        android:layout_width="match_parent"
        android:layout_height="0dip"
        android:layout_weight="1.04"
        android:fillViewport="true"
        android:keepScreenOn="true"
        android:scrollbarStyle="insideInset"
        android:scrollbars="vertical"
        android:visibility="visible" >

        <TextView
            android:id="@+id/detailsText"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            <!--android:layout_gravity="center_horizontal|center_vertical" -->      android:layout_marginTop="30dip" />
    </ScrollView>
